How to make Broccoli Cheese Casserole

Making Broccoli Cheese Casserole is simple and straightforward. Just follow these steps, and you will have a delicious dish ready in no time!

Ingredients

4 cups fresh broccoli florets (or frozen, thawed and drained)
½ medium onion, finely chopped
2 cloves garlic, minced
1 tablespoon olive oil
1 (10.5 oz) can condensed cream of mushroom or cream of chicken soup
½ cup sour cream
½ cup mayonnaise
1 ½ cups shredded cheddar cheese, divided
¼ teaspoon black pepper
¼ teaspoon salt
½ teaspoon paprika (optional)
½ cup crushed Ritz crackers or breadcrumbs
2 tablespoons melted butter

Directions

Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch or similar-sized baking dish to prevent sticking.
Steam or blanch the broccoli florets until just crisp-tender. It will take around 2–3 minutes for fresh broccoli. Once done, drain well and set aside to remove any excess moisture.
In a skillet, heat the olive oil over medium heat. Add the finely chopped onion and sauté for about 3–4 minutes until softened. Add the minced garlic and sauté for an additional 30 seconds to release its wonderful aroma.
In a large mixing bowl, combine the condensed cream of mushroom or chicken soup, sour cream, mayonnaise, the sautéed onion and garlic, 1 cup of the shredded cheddar cheese, salt, pepper, and paprika if you are using it. Stir well to blend all the ingredients smoothly.
Fold the cooked broccoli into the creamy mixture, making sure all pieces of broccoli are evenly coated.
Transfer the broccoli mixture into the prepared baking dish. Evenly sprinkle the remaining ½ cup of shredded cheddar cheese on top.
In a small bowl, mix the crushed Ritz crackers or breadcrumbs with the melted butter until well combined. Then, sprinkle this buttery topping evenly over the cheese layer.
Place the casserole in the preheated oven and bake uncovered for 25–30 minutes, or until the casserole is bubbly and the topping is golden brown and crisp.
Once baked, remove the casserole from the oven and let it rest for 5 minutes before serving. This helps the dish set slightly and improves the flavor.

Nutritional benefits

This Broccoli Cheese Casserole not only delights the taste buds but also offers various nutritional benefits. Broccoli is a nutrient powerhouse rich in vitamins C and K, fiber, and antioxidants. It supports immune function and bone health while promoting good digestion due to its fiber content.

The cheese adds protein and calcium to your meal, which are important for maintaining strong bones and muscles. While mayonnaise and sour cream contribute to the richness and creaminess, they also provide some fats which can help with the absorption of fat-soluble vitamins from the broccoli.

In moderation, this casserole can fit into a balanced diet, especially if served alongside lean proteins and whole grains.

What to Serve With Broccoli Cheese Casserole

This Broccoli Cheese Casserole pairs wonderfully with several side dishes and proteins. Consider serving it alongside:

Grilled Chicken: The light flavors of grilled chicken complement the creaminess of the casserole.
Pork Chops: Juicy pork chops provide delicious protein that matches the richness of the casserole.
Salad: A fresh green salad can balance the meal and add a crunch. Toss in some cherry tomatoes, cucumbers, and a light vinaigrette.
Rice: Fluffy rice, whether white or brown, serves as a great side to soak up the cheesy goodness.

How to store Broccoli Cheese Casserole

If you want to keep it longer, consider freezing it. Make sure to place it in a freezer-safe container or wrap it well with plastic wrap and aluminum foil. Thaw in the fridge overnight before reheating. To reheat, simply pop it in the oven at 350°F (175°C) until warmed through.

Tips and Mistakes to Avoid

Don’t Overcook Broccoli: Make sure you don’t overcook the broccoli, as it can become mushy and lose its vibrant color. A crisp-tender texture is ideal.
Proper Mixing: Ensure that all ingredients are mixed well to avoid pockets of dry ingredients in the casserole.
Adjust Taste Early: Before baking, taste the mixture and adjust seasoning if necessary. It’s easier to tweak before cooking.
Watch the Topping: Keep an eye on the topping to avoid burning. If it browns too quickly, cover it with foil.

Add Chicken or Tuna: Mix in shredded cooked chicken or canned tuna for added protein and heartiness.
Different Cheeses: Experiment with different types of cheese like mozzarella, pepper jack, or gouda for a flavor twist.
Vegetable Mix-Ins: Consider adding other vegetables like cauliflower, carrots, or bell peppers to enhance nutritional content.
