Ingredients
Scale
Broccoli
- 4 cups fresh or frozen broccoli florets (steamed or blanched)
Cheese Mixture
- 1 can (10.5 oz) condensed French onion soup
- 1 cup sour cream
- 1 cup shredded cheddar cheese
- ½ cup shredded mozzarella cheese
- 1 teaspoon garlic powder
- ½ teaspoon black pepper
- ½ teaspoon salt (adjust to taste)
Toppings
- 1 cup crispy fried onions (divided)
- ½ cup crushed Ritz crackers (optional, for extra crunch)
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to prevent sticking.
- Prepare Broccoli: If using fresh broccoli, blanch it in boiling water for 2 minutes to soften, then drain thoroughly. If using frozen broccoli, thaw completely and drain any excess moisture to avoid a watery casserole.
- Mix Ingredients: In a large bowl, combine condensed French onion soup, sour cream, shredded cheddar cheese, shredded mozzarella cheese, garlic powder, black pepper, and salt. Stir the mixture well until evenly blended, then fold in the prepared broccoli until all florets are coated.
- Assemble: Transfer the broccoli and cheese mixture to your greased baking dish and spread it out evenly to form a uniform layer.
- Top It Off: Sprinkle half of the crispy fried onions evenly over the top of the casserole. If you like extra crunch and flavor, add the optional crushed Ritz crackers as well.
- Bake: Place the casserole in the preheated oven and bake for 25 minutes until the mixture is bubbly and the top is golden brown.
- Final Touch: Remove the casserole from the oven, sprinkle the remaining crispy fried onions on top, and return it to the oven for an additional 5 minutes. This step ensures the topping is extra crisp and delicious.
- Serve: Let the casserole cool for a few minutes before serving warm. Enjoy the creamy, cheesy, and crunchy textures that make this dish so comforting and satisfying.
Notes
- You can substitute the broccoli with cauliflower or a mix of green vegetables for variety.
- Adjust salt and pepper to taste, especially if your French onion soup is salty.
- For a gluten-free version, replace the crispy fried onions and Ritz crackers with gluten-free alternatives.
- This casserole reheats well and can be stored covered in the refrigerator for up to 3 days.
- To make it lower fat, use reduced-fat sour cream and cheeses.
