How to Make Creamy Broccoli Casserole Recipe
Step 1: Prepare the Oven and Broccoli
Start by preheating your oven to 350°F (175°C). Lightly grease a 2-quart baking dish so nothing sticks and cleanup stays easy. Steam or blanch the broccoli florets until they are just tender—about 3 to 4 minutes—which keeps them perfectly crisp and vibrant in color. Drain the broccoli well and set it aside while you move to the next step.
Step 2: Sauté Onion and Garlic
In a skillet over medium heat, melt 1 tablespoon of butter. Add the chopped onion and cook gently until it becomes soft and translucent, around 5 minutes. This allows the onions to develop a lovely sweetness that balances the dish. Throw in the minced garlic next and cook it just for a minute, enough to release its aroma without burning it.
Step 3: Mix the Creamy Sauce
In a large mixing bowl, combine your sautéed onions and garlic with the cream of mushroom soup, sour cream, shredded cheddar cheese, salt, black pepper, and paprika. Stir everything until it forms a smooth, creamy mixture ready to envelop the broccoli. This sauce is what makes the casserole irresistibly luscious and full of flavor.
Step 4: Combine Broccoli and Cream Mixture
Gently fold the steamed broccoli into your cream sauce until every floret is well coated. Be careful not to mash the broccoli; you want those nice little pieces intact so they deliver texture in every bite. Then pour this mixture into your prepared baking dish and spread it evenly.
Step 5: Prepare the Topping and Bake
Take a small bowl and mix the crushed buttery crackers or breadcrumbs with 2 tablespoons of melted butter. This topping will add a golden, crispy layer that contrasts beautifully with the creamy casserole underneath. Sprinkle the topping evenly over the broccoli mixture. Pop your dish into the oven and bake for 25 to 30 minutes, until it’s bubbling around the edges and the top is a gorgeous golden brown.
Step 6: Cool Slightly and Serve
Once baked, let your casserole cool for a few minutes before serving. This helps everything settle, making it easier to scoop out perfect portions without the sauce running away. Now you’re ready to enjoy every bite of this comforting Creamy Broccoli Casserole Recipe!

Garnishes
Fresh herbs like chopped parsley or chives add a pop of color and a fresh aroma, brightening the creamy richness of the casserole. A sprinkle of extra shredded cheddar cheese or a light dusting of smoked paprika can also make the dish look even more inviting on your plate.

Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers to an airtight container and store them in the refrigerator. Your Creamy Broccoli Casserole Recipe will stay fresh and delicious for up to 3 days, making it easy to enjoy multiple meals without extra cooking.
Freezing
This casserole freezes wonderfully. Simply assemble it in a freezer-safe dish but do not bake before freezing. Wrap tightly in plastic wrap and aluminum foil, then freeze for up to 2 months. When you’re ready, bake from frozen, adding a little extra baking time to ensure it’s heated through and bubbly.
Reheating
To reheat leftovers, warm the casserole in the oven at 350°F (175°C) until heated through and the topping crisps back up, about 15 to 20 minutes. Avoid the microwave if possible to keep the crunchy topping intact and the casserole creamy and delicious.
FAQs
Can I use frozen broccoli for this casserole?
Yes, frozen broccoli can be used if fresh isn’t available. Just be sure to thaw and drain it well to prevent excess moisture from making the casserole watery.
What can I substitute for the cream of mushroom soup?
If you’re not a fan of mushroom, cream of chicken soup works great and provides the same creamy texture with a slightly different flavor.
Is this casserole vegetarian-friendly?
Absolutely! This recipe uses vegetarian ingredients and is perfect for meat-free meals, but always double-check soup labels if you want to be certain about animal products.
Can I add protein to make this a main dish?
Yes, adding shredded rotisserie chicken or cooked rice before baking gives it extra heartiness and transforms it from a side into a satisfying main course.
How do I get the topping extra crispy?
Make sure to mix the crushed crackers or breadcrumbs with melted butter thoroughly, and avoid covering the casserole during baking. A quick burst under the broiler at the end can also help achieve a golden, crispy finish.
