Introduction

This French Onion Broccoli Cheese Casserole is a comforting and flavorful dish that combines tender broccoli with creamy cheeses and savory French onion soup. Topped with crispy fried onions and crunchy crackers, it’s perfect as a hearty side or a satisfying vegetarian main.

Ingredients

• 4 cups fresh or frozen broccoli florets (steamed or blanched)
• 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)
• 1 cup crispy fried onions (divided)

Instructions

1. Step 1: Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Step 2: Prepare the broccoli. If using fresh broccoli, blanch it in boiling water for 2 minutes, then drain well. If using frozen, thaw and drain any excess moisture.
3. Step 3: In a large bowl, combine the French onion soup, sour cream, cheddar cheese, mozzarella cheese, garlic powder, black pepper, and salt. Stir in the prepared broccoli until evenly coated.
4. Step 4: Transfer the mixture to the prepared baking dish and spread it out evenly.
5. Step 5: Sprinkle half of the crispy fried onions and the crushed Ritz crackers (if using) evenly over the top.
6. Step 6: Bake uncovered for 25 minutes, until the casserole is bubbly and golden brown.
7. Step 7: Remove from the oven, sprinkle the remaining crispy fried onions on top, and bake for an additional 5 minutes until they are crisp and golden.
8. Step 8: Serve warm and enjoy the creamy, cheesy, and crunchy goodness.

Tips & Variations

• For extra flavor, add a handful of cooked, crumbled bacon to the mixture before baking.
• Use gluten-free crackers and fried onions to make this dish gluten-free.
• Swap out mozzarella for Monterey Jack or pepper jack for a different cheese twist.
• Fresh broccoli gives a better texture, but frozen works well in a pinch—just make sure to drain thoroughly.
• Add chopped green onions or chives as a fresh garnish before serving for extra color and flavor.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the entire dish covered with foil in a 350°F oven until heated through. The crispy onion topping may lose some crunch after reheating.

FAQs

Can I make this casserole ahead of time?

Yes, you can assemble the casserole a day ahead, cover it with foil, and refrigerate. Bake it just before serving, adding a few extra minutes to the cooking time if baking from cold.

Can I use a different type of soup instead of French onion?

French onion soup adds a unique savory flavor, but you can substitute with cream of mushroom or cream of celery soup for a different taste.
