Variations & Substitutions

Broccoli florets. I recommend using fresh broccoli florets since they have a richer flavor, firmer texture, and less moisture than frozen ones. If using frozen broccoli florets, dry with a paper towel after steaming to remove excess moisture. Cream of mushroom soup. I used a can of condensed cream of mushroom soup for this recipe, but if you’re not a fan of mushroom, cream of broccoli, cream of celery, or even coconut milk can be used instead. Cheddar cheese. The best cheese for this recipe is sharp cheddar cheese. But as an alternative, you can use Colby Jack, Gruyere, Monterey Jack, or mozzarella for a creamy cheese sauce. You can also use vegan cheese alternatives. Season with salt, black pepper, and garlic powder as desired!

📖 How to make broccoli cheese casserole recipe

Step 1: Preheat the oven to 400°F. Grease or spray a square baking dish (8 inch) with nonstick cooking spray and set it aside. Step 3: Transfer the broccoli to a prepared baking dish. Pour the cream of mushroom soup over the broccoli. Toss and stir to coat if desired. Microwave the broccoli for 3-4 minutes until it becomes crisp-tender. Drain the broccoli by placing it in a colander. Step 4:Top the broccoli mixture with cheese and bake for 15-20 minutes, or until the cheese melts and becomes lightly golden brown.

👩🏽‍🍳 Tips for the best broccoli cheese casserole

Making this 3-ingredient broccoli cheese casserole is a piece of cake, but make sure to follow these tips to make them perfect each time! ⭐ Be careful to not overcook the broccoli, as it will continue to cook during the casserole baking. Check the consistency with a fork every minute to make sure they are tender but still firm and crisp.

After steaming the florets, place them in an ice bath to quickly cool them to stop them from continuing to cook. This will prevent them from becoming too soft or soggy in the casserole, and help preserve the color. Sprinkle breadcrumbs or crushed ritz crackers on top before baking for a nice crunch. Mix cheddar with other cheeses like Gruyere for a nuanced flavor profile. Sprinkle fresh herbs like parsley or chives to your casserole right before serving.
