Ingredients You’ll Need
The beauty of this Creamy Broccoli Casserole Recipe lies in its simplicity.

The pantry staples like garlic and onion powder quietly boost the flavor, while the buttery cracker topping gives it that irresistible crunch.
- 4 cups fresh broccoli florets (or frozen, thawed and drained): Choose fresh for the best texture or thawed frozen for convenience.
- 1 tablespoon olive oil (if using fresh broccoli): Helps gently soften the broccoli when steaming or sautéing.
- 1 (10.5 oz) can cream of mushroom soup (or cream of chicken soup): Creates the creamy base that brings everything together.
- 1/2 cup sour cream: Adds tanginess and richness to the sauce.
- 1 cup shredded cheddar cheese, divided: Provides cheesy flavor and melty texture.
- 1/4 cup grated Parmesan cheese: Gives a sharp, nutty punch to the overall flavor.
- 1/4 cup milk: Thins the sauce just enough for a smooth consistency.
- 1/2 teaspoon garlic powder: Infuses subtle, aromatic depth.
- 1/2 teaspoon onion powder: Enhances savory notes without overpowering.
- Salt and pepper, to taste: Balances and brightens the flavors.
- 1 cup crushed buttery crackers (such as Ritz): Essential for that golden, crunchy topping.
- 2 tablespoons melted butter (for topping): Binds the cracker crumbs and adds richness.
How to Make Creamy Broccoli Casserole Recipe
Step 1: Prepare the Broccoli
If you’re working with fresh broccoli, start by steaming or blanching the florets just until they turn tender but stay vibrantly green—about 5 to 6 minutes. This quick cooking keeps them crisp-tender, which provides a fantastic texture contrast. For frozen broccoli, make sure to fully thaw and drain it so the casserole won’t turn watery. This step sets a great foundation for the whole dish.
Step 2: Make the Creamy Sauce
In a large bowl, mix together the cream of mushroom soup, sour cream, milk, garlic powder, onion powder, and the grated Parmesan cheese. Stir everything until the sauce feels silky and well blended. Then fold in half of the shredded cheddar cheese, which enriches the sauce with a smooth, cheesy undertone that makes the casserole so irresistible.
Step 3: Combine with Broccoli
Gently toss the cooked broccoli into your creamy sauce until every floret is beautifully coated. This ensures you get a perfect balance of sauce to broccoli in every bite. Then season the mixture with salt and pepper to enhance the flavors and bring the casserole to life.
Step 4: Assemble the Casserole
Transfer your broccoli mixture to a greased 9×13-inch baking dish, smoothing the top evenly with a spatula. Taking a moment to spread it out ensures it bakes consistently for that beautiful, even texture we all love in a casserole.
Step 5: Prepare the Topping
Combine the crushed buttery crackers with melted butter in a small bowl, mixing until the crumbs are well coated. Sprinkle this crumbly, buttery topping generously over the broccoli mixture. Then, sprinkle the remaining cheddar cheese over the cracker topping for an extra cheesy, golden finish that will make your casserole irresistible.
Step 6: Bake
Pop the casserole into a preheated oven at 350°F (175°C) and bake for 25 to 30 minutes. You’ll know it’s ready when the top turns a gorgeous golden brown and the edges bubble invitingly. This baking step melds all the flavors and textures into one harmonious dish.
Step 7: Serve
Let the casserole rest for a few minutes after it comes out of the oven to set slightly—that way, it holds together better when you scoop it. Then dig in and savor the creamy, cheesy, crunchy goodness all in one dish.

Freezing
You can freeze this casserole before baking by assembling it in a freezer-safe dish, covering tightly with foil or plastic wrap. Freeze for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator, then bake as directed, adding a few extra minutes to the baking time if needed.
Reheating
To reheat, place portions in an oven-safe dish and bake at 350°F (175°C) until warmed through, which usually takes about 15 to 20 minutes. For microwave reheating, cover loosely and heat in 1-minute increments, stirring midway to heat evenly without drying out.
FAQs
Can I use cream of chicken soup instead of cream of mushroom?
Absolutely! Using cream of chicken soup adds a milder flavor and is a great alternative if you prefer a non-vegetarian option in your Creamy Broccoli Casserole Recipe.
Is there a way to make this casserole gluten-free?
Yes, you can substitute the buttery crackers with gluten-free crackers or crushed gluten-free cornflakes. Just be sure to check that your soup and other ingredients are gluten-free as well.
Can I add other vegetables to this casserole?
Definitely! Feel free to mix in vegetables like cauliflower, carrots, or mushrooms to add variety and extra nutrients—just steam them along with your broccoli before combining with the sauce.
How can I make this casserole less rich?
To lighten it up, try using reduced-fat sour cream and cheese, and swap whole milk for a lower-fat version. You can also reduce the amount of cheese slightly without sacrificing too much flavor.
What is the best way to get the topping extra crispy?
Using melted butter to coat the cracker crumbs helps achieve that perfect golden crunch. For an even crispier top, you can broil the casserole for the last 2-3 minutes, but watch closely to avoid burning.
