There’s a special kind of magic that happens when humble broccoli meets a rich, creamy cheese sauce, all capped with a buttery, golden cracker crust. It’s the kind of dish that quiets a busy dinner table, where the only sounds are satisfied murmurs and the gentle scrape of spoons against plates. As a chef who has spent years in high-pressure kitchens, I’ve come to appreciate the profound comfort of a perfectly executed casserole.
This one is my weeknight hero—a recipe that delivers restaurant-quality flavor with straightforward, reliable techniques. It’s creamy without being gloppy, crisp on top without being dry, and deeply satisfying in a way that only true comfort food can be. Let’s make it.
This isn’t just another casserole. It’s a carefully tested formula designed for maximum payoff with minimal fuss. Here’s why it will become a regular in your rotation:
- From-Scratch Flavor: By making a simple roux-based cheese sauce instead of using canned soup, we build layers of flavor you can actually taste. The sharp cheddar, Dijon, and aromatics create a complex, grown-up sauce that still pleases kids.
- Perfect Broccoli Texture: The crucial step of blanching the broccoli before baking ensures it emerges tender-crisp and vibrant green, not waterlogged or mushy. It’s a professional technique that makes all the difference.
- The Ultimate Topping: The combination of buttery Ritz crackers and extra cheese bakes into an irresistible, shatteringly crisp crust that provides the perfect textural contrast to the creamy filling.
- Meal-Planning Friendly: This casserole assembles quickly, can be prepped ahead, and reheats beautifully. It’s the answer for busy nights, potlucks, or when you need to deliver a meal to a friend.
- Endlessly Adaptable: The base recipe is a fantastic canvas. I’ll show you how to easily customize it with different proteins, cheeses, and vegetables to suit what you have on hand.
Ingredients You’ll Need
- Let’s gather our ingredients—this is where simple pantry staples transform into something truly special. Using quality components here pays off in flavor. Trust me, the block of cheddar you shred yourself melts far more smoothly than pre-shredded cheese (which contains anti-caking agents). For the broccoli, fresh florets are ideal, but a bag of frozen, thawed broccoli works perfectly in a pinch. The Ritz crackers are non-negotiable for their buttery flavor and ideal crushability, but I’ll give you great alternatives below.
- Broccoli Florets: The star of the show. We’ll blanch them to lock in color and perfect texture.
- Unsalted Butter: Divided for the sauce and the topping. Using unsalted lets you control the seasoning.
- Yellow Onion & Garlic: The aromatic foundation. Finely dicing the onion ensures it melts into the sauce.
- All-Purpose Flour: This is our thickening agent for the roux, creating the base of a silky, stable cheese sauce.
- Whole Milk & Broth: Whole milk gives the sauce richness, while broth (chicken or vegetable) adds a savory depth. Warm them slightly before adding to prevent the sauce from seizing.
- Dijon Mustard & Paprika: These are my secret flavor amplifiers. Dijon adds a subtle tang that brightens the cheese, and paprika gives warmth and color.
- Sharp Cheddar Cheese: Please shred it yourself from a block. The flavor is superior, and it melts into a smooth, creamy sauce without any grittiness.
- Ritz Crackers: They create the iconic, buttery, crispy topping. Crush them by hand for the best texture.

Kitchen Equipment Needed
You don’t need any specialty gear for this recipe. A 9×13 inch baking dish is the perfect size. A large saucepan or Dutch oven is ideal for making the cheese sauce, and a large pot for blanching the broccoli.
A good whisk is essential for creating a lump-free roux. That’s really it. If you don’t have a Dutch oven, any sturdy pot will do.
For crushing the crackers, a zip-top bag and a rolling pin (or even a can) work perfectly.
How to Make Broccoli & Cheese Cracker Casserole Recipe
Step 1: Blanch the Broccoli
Bring a large pot of well-salted water to a rolling boil—it should taste like the sea. This seasons the broccoli from within. Add your florets and cook for just 3-4 minutes.
You’re not cooking them through, just taking the raw edge off. The moment they turn bright green, drain them and immediately shock them in a bowl of ice water. This stops the cooking instantly, preserving that beautiful color and perfect tender-crisp bite.
Believe me, this step is what separates a great casserole from a mediocre, mushy one. Drain them thoroughly again; excess water will thin your sauce.
Step 2: Build the Flavor Base (The Roux)
In your large saucepan, melt 2 tablespoons of butter over medium heat. Add the diced onion and cook, stirring occasionally, until it’s soft and translucent—about 5 minutes. Now add the garlic and cook for just 60 seconds until fragrant; any longer and it risks burning.
Sprinkle the flour over the onions and garlic. This is your roux. Cook, stirring constantly, for a full 2 minutes.
This cooks out the raw flour taste and gives your sauce a nutty, toasted foundation. It should look like a wet, pale sand.
Step 3: Create the Cheese Sauce
Here’s where the magic happens. Gradually pour in your slightly warmed milk and broth while whisking constantly. A gradual pour and steady whisking are the keys to a smooth, lump-free sauce.
Bring the mixture to a gentle simmer. It will thicken noticeably as it heats, enough to coat the back of a spoon. Remove the pot from the heat.
Now, whisk in the Dijon, paprika, nutmeg, salt, and pepper. The residual heat is perfect for melting the cheese. Stir in 2 cups of the shredded cheddar until the sauce is velvety and smooth.
Take a taste and adjust the seasoning—this is your last chance before baking.
Step 4: Assemble the Casserole
Gently fold your perfectly blanched and drained broccoli florets into the luxurious cheese sauce. You want every floret to be generously coated. Pour this mixture into your greased baking dish and spread it into a beautiful, even layer.
Now for the fun part: the topping. Melt the last tablespoon of butter and mix it with the crushed Ritz crackers and the remaining 1/2 cup of cheese. Sprinkle this over the casserole in an even, tempting layer.
Tip from me: use your fingers for the topping to create clumps and varying sizes for maximum crispiness.
Step 5: Bake, Rest, and Serve
Slide the casserole into your preheated 375°F oven. Bake for 25-30 minutes. You’re looking for the filling to be bubbly vigorously around the edges and that gorgeous cracker topping to be a deep, golden brown.
Once out of the oven, this is critical: let it rest on the counter for 5-10 minutes. This allows the sauce to set slightly so you get clean, beautiful servings instead of a cheesy lava flow. Step back and admire your work, then dish it up.
A few insights from my years in the kitchen will guarantee your success every single time.
- The Roux Rule: Don’t rush the roux. Cooking the flour and butter for a full 2 minutes is essential. If it’s undercooked, your sauce will taste faintly of raw flour. If you see it darkening beyond a pale blonde, your heat is too high.
- Cheese Science: Always shred your own cheese from a block. Pre-shredded cheese is coated in potato starch or cellulose to prevent clumping, which can make your sauce grainy or prevent it from melting smoothly. Sharp cheddar has less moisture than mild, making for a richer, more stable sauce.
- Shocking Success: The ice bath for the broccoli isn’t just for color. It halts the enzymatic cooking process, ensuring the florets stay firm and don’t turn to mush during their second cook in the oven.
- Resting is Part of Cooking: That 10-minute rest after baking is non-negotiable. It allows the proteins in the cheese and the starch in the sauce to relax and re-bond, transforming a loose filling into a sliceable, scoopable masterpiece.
Recipe Variations
- This recipe is wonderfully adaptable. Here are some of my favorite tested twists.
- Protein Power: Add 2 cups of diced cooked chicken, ham, or shredded rotisserie chicken to the filling for a complete one-dish meal. For a vegetarian protein boost, stir in a can of drained, rinsed white beans or chickpeas.
- Cheese Swap: Try using a combination of cheeses. Gruyère adds a nutty sophistication, Monterey Jack brings excellent melt, and a few tablespoons of grated Parmesan in the topping adds a salty punch.
- Gluten-Free & Low-Carb: For a gluten-free version, use a 1:1 gluten-free flour blend for the roux and crushed gluten-free crackers or pork rinds for the topping. For lower carb, replace the crackers with crushed pork rinds or a mixture of almond flour and grated Parmesan.
- Vegetable Medley: While broccoli is classic, this sauce is fantastic with other vegetables. Try it with cauliflower, a mix of broccoli and carrots, or even with sautéed mushrooms and spinach.
- Spicy Kick: Add a pinch of cayenne pepper to the sauce or mix a 1/4 teaspoon of smoked paprika and a dash of hot sauce into the filling for a gentle warmth.
What to Serve With This Recipe
This casserole is rich and satisfying, so I love to pair it with lighter, acidic sides to create balance. A simple mixed green salad with a bright lemon vinaigrette is perfect. For a heartier meal, it pairs beautifully with roasted chicken breasts or pan-seared sausages.
If you’re serving it for a holiday or potluck, it’s a stellar side to baked ham or roast turkey. Beverage-wise, a crisp apple cider, a light lager, or a dry unoaked Chardonnay all work wonderfully to cut through the richness.
Storage & Make-Ahead Instructions
- This casserole is a meal-prepper’s dream.
- Refrigeration: Cool the baked casserole completely, then cover tightly with plastic wrap or transfer to an airtight container. It will keep in the refrigerator for 3-4 days.
- Freezing: For best results, freeze before baking. Assemble the casserole right up to the point of adding the topping. Wrap the entire dish tightly in a layer of plastic wrap and then a layer of foil. Freeze for up to 2 months. Thaw overnight in the refrigerator, add the topping, and bake as directed, adding 5-10 minutes to the bake time.
- Reheating: Reheat individual portions in the microwave until hot. For larger amounts, cover with foil and reheat in a 350°F oven for 15-20 minutes. For a crisp topping, remove the foil for the last 5 minutes.
- Make-Ahead: You can assemble the entire casserole (with topping) up to 24 hours in advance. Cover and refrigerate. When ready to bake, you may need to add 5-8 minutes to the baking time since it’s starting from cold.
Frequently Asked Questions
Q: Can I use frozen broccoli without thawing it first?
A: I don’t recommend it. Frozen broccoli releases a significant amount of water as it bakes, which can make your casserole soupy. If using frozen, thaw it completely and press it in a clean kitchen towel to remove as much excess moisture as possible.
Q: My cheese sauce seems grainy. What happened?
A: Graininess usually occurs from overheating the cheese or using pre-shredded cheese. Always remove the sauce from the heat before stirring in the cheese. The residual heat is enough to melt it smoothly.
Also, ensure you’re shredding your own cheese from a block.
Q: Can I make this casserole ahead and bake it later?
A: Absolutely. Follow the instructions through assembly (including adding the topping), cover tightly, and refrigerate for up to 24 hours. You may need to add 5-8 extra minutes to the bake time since it will be going into the oven cold.
Q: What can I use instead of Ritz crackers?
A: Buttery crackers like Club crackers, Town House, or even crushed saltines work well. For a different twist, try using panko breadcrumbs tossed with melted butter and a little Parmesan cheese.
Q: How do I know when the casserole is done baking?
A: Look for three signs: 1) The filling should be bubbling actively around the edges, 2) The center should be hot (an instant-read thermometer should read 165°F), and 3) The cracker topping should be a uniform golden brown.
Q: Is it necessary to blanch the broccoli? Can’t I just use it raw?
A: You can use raw broccoli, but the texture and color won’t be as good. Raw broccoli takes much longer to cook in the oven, often resulting in a watery casserole and potentially overcooked edges before the center is done. Blanching ensures even, perfect tenderness.
Q: Can I make this recipe gluten-free?
A: Yes, successfully. Use a certified gluten-free 1:1 flour blend for the roux and substitute the Ritz crackers with crushed gluten-free crackers or a mixture of gluten-free panko and Parmesan cheese.
Q: The topping got too dark before the casserole was bubbly. How do I prevent this?
A: If you notice the topping browning too quickly, loosely tent the casserole with a piece of aluminum foil for the remainder of the baking time. This will shield the topping while allowing the heat to penetrate and bubble the filling.

Easy Broccoli & Cheese Cracker Casserole
Equipment
- 9×13 inch baking dish
- Large pot
- Large saucepan or Dutch oven
- Whisk
- Mixing bowls
- Colander
Ingredients
- 1 lb broccoli florets fresh or frozen (thawed if frozen)
- 3 tbsp unsalted butter divided
- 1/2 cup yellow onion finely diced
- 2 cloves garlic minced
- 3 tbsp all-purpose flour
- 1 1/2 cups whole milk warmed slightly
- 1 cup chicken or vegetable broth
- 1 tsp Dijon mustard
- 1/2 tsp paprika
- 1/4 tsp ground nutmeg optional but recommended
- 2 1/2 cups sharp cheddar cheese shredded, divided
- 1 cup Ritz crackers crushed (about 1 sleeve)
- Kosher salt and black pepper to taste
Instructions
- Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish. Bring a large pot of salted water to a boil. Add the broccoli florets and cook for 3-4 minutes until bright green and just tender-crisp. Immediately drain and plunge into a bowl of ice water to stop the cooking. Drain well and set aside. This blanching step is key for perfect texture.
- In a large saucepan or Dutch oven, melt 2 tablespoons of butter over medium heat. Add the diced onion and cook for 4-5 minutes until softened. Add the garlic and cook for 1 more minute until fragrant. Sprinkle the flour over the onions and garlic, and cook, stirring constantly, for 2 minutes to make a roux. This cooks out the raw flour taste.
- Gradually whisk in the warm milk and broth, ensuring no lumps form. Bring the mixture to a simmer, whisking frequently, until it thickens enough to coat the back of a spoon, about 3-4 minutes. Remove from heat. Whisk in the Dijon mustard, paprika, nutmeg, 1/2 teaspoon of salt, and 1/4 teaspoon of pepper.
- Stir in 2 cups of the shredded cheddar cheese until melted and smooth. Gently fold in the blanched and drained broccoli florets until evenly coated. Pour the cheesy broccoli mixture into your prepared baking dish and spread it into an even layer.
- In a small bowl, melt the remaining 1 tablespoon of butter. Mix it with the crushed Ritz crackers and the remaining 1/2 cup of shredded cheddar. Sprinkle this topping evenly over the casserole. Bake for 25-30 minutes, until the filling is bubbly around the edges and the topping is deeply golden brown. Let it rest for 5-10 minutes before serving to allow it to set.
