- 1 can (10.5 oz) condensed cream of mushroom soup: Creamy binder that adds earthiness and comfort.
- 1/2 cup sour cream: Brings tanginess and a velvety texture.
- 1/2 teaspoon garlic powder: Adds a subtle aromatic warmth enhancing all flavors.

How to Make Broccoli Cheese Casserole Recipe
Step 1: Prepare the Broccoli
Start by steaming or blanching your broccoli for 3 to 4 minutes until just tender. This keeps the florets bright green and prevents them from becoming mushy during baking. Drain well so the final casserole isn’t watery.
Step 2: Sauté the Onions
While the broccoli is cooking, melt the butter in a skillet over medium heat and gently sauté the chopped onions for about 3 to 4 minutes until they’re soft and fragrant. This step enhances the sweetness and adds a beautiful base flavor to your casserole.
Step 3: Mix the Sauce
In a large mixing bowl, combine the cooked onions, cream of mushroom soup, sour cream, garlic powder, black pepper, and 1 cup of the shredded cheddar cheese. Stir it well to create a creamy, flavorful sauce that will coat every bite of broccoli perfectly.
Step 4: Combine and Transfer
Add the steamed broccoli to the sauce mixture and stir gently to ensure every floret is covered generously with the cheesy mixture. Then, pour everything into your greased 9×9-inch baking dish, spreading evenly.
Step 5: Add Topping and Bake
Sprinkle the remaining 1/2 cup of cheddar cheese over the top, followed by the crushed buttery crackers. This topping will bake to a golden, crispy finish that’s simply irresistible. Pop the dish into a preheated 350°F oven and bake for 25 to 30 minutes until bubbly and golden.
How to Serve Broccoli Cheese Casserole Recipe

Garnishes
For a finishing touch, sprinkle freshly chopped parsley or chives on top of the casserole before serving. This not only adds a splash of fresh color but also a subtle herbal note that brightens up the rich flavors.
Side Dishes
This broccoli cheese casserole pairs wonderfully with roasted meats like turkey, chicken, or pork. It also complements lighter mains such as grilled fish or a simple quinoa salad, making it extremely versatile at any dining table.
Creative Ways to Present
Try serving this casserole in individual ramekins for a charming, personalized touch during dinner parties. You can also turn it into a one-pan meal by stirring in cooked rice or shredded rotisserie chicken before baking, giving you a hearty, complete dish all in one.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors actually develop further, making for an even tastier meal the next day.
Freezing
Broccoli cheese casserole freezes well uncooked. Assemble the dish as directed, cover tightly with foil, and freeze for up to 2 months. When ready to enjoy, bake straight from frozen (add extra baking time) for a convenient, make-ahead option.
Reheating
To reheat, place servings in a microwave-safe dish and cover loosely, heating in short intervals until warmed through. For best texture, reheat leftovers in a conventional oven at 350°F for about 15 minutes to re-crisp the cracker topping.
FAQs
Can I use frozen broccoli instead of fresh?
Absolutely! Just be sure to thaw and drain it well to avoid excess moisture, which can make the casserole soggy. Frozen broccoli works well and offers year-round convenience with little difference in taste.
What can I substitute for cream of mushroom soup?
You can swap in cream of chicken or cream of celery soup if you prefer, or if you want a milder flavor. Also, homemade mushroom soup can be used to reduce preservatives and customize the taste.
Is this casserole suitable for vegetarians?
Yes! This Broccoli Cheese Casserole Recipe is perfect for vegetarians as it contains no meat. Just double-check your soup label to ensure there are no animal-based ingredients included.
Can I add more cheese?
Definitely! Feel free to increase the cheddar cheese quantity or incorporate different types like mozzarella or Monterey Jack for an extra cheesy variation that melts beautifully.
How do I make this recipe gluten-free?
Simply replace the buttery crackers topping with gluten-free crackers or crushed gluten-free cereal. Also, be sure the condensed soup you choose is gluten-free, as some brands may contain wheat.
