- 1 cup breadcrumbs or crushed crackers for topping

Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or casserole dish.
2. Cook the Ground Beef Mixture
- In a large skillet over medium heat, cook the ground beef until browned.
- Add chopped onions, garlic, and diced bell peppers. Cook until vegetables are softened (about 5 minutes).
- Season with salt, pepper, and paprika or chili powder.
- Stir in drained diced tomatoes and cooked rice or pasta (if using). Cook for 2–3 more minutes to combine flavors. Remove from heat.
3. Prepare the Creamy Layer
- In a separate bowl, mix sour cream (or cream of mushroom soup), milk, and Worcestershire sauce until smooth.
- Fold in 1 cup of shredded cheese.
4. Assemble the Casserole
- Spread the ground beef mixture evenly in the prepared baking dish.
- Pour the creamy cheese mixture over the beef layer and spread evenly.
- Sprinkle the remaining 1 cup of cheese on top.
5. Add the Topping
- In a small bowl, mix breadcrumbs or crushed crackers with melted butter.
- Sprinkle evenly over the cheese layer for a golden, crunchy topping.
6. Bake
Bake in the preheated oven for 25–30 minutes, or until cheese is melted, bubbly, and the topping is golden brown.
7. Serve
Allow the casserole to cool slightly for 5 minutes. Serve hot, garnished with fresh parsley or green onions if desired.
Tips for the Perfect Ground Beef Casserole
- Use 80/20 ground beef: Ensures a juicy, flavorful base.
- Cook vegetables first: Adds sweetness and depth to the filling.
- Don’t overcook: Bake just until bubbly to avoid drying out.
- Customize your toppings: Use crushed tortilla chips or fried onions for variety.
- Let it rest: Helps the layers set, making it easier to slice and serve.
Variations
1. Cheesy Taco Casserole
Add taco seasoning to the beef mixture, layer with salsa, and top with cheddar cheese for a Mexican-inspired twist.
2. Italian Ground Beef Casserole
Add cooked pasta, marinara sauce, and mozzarella cheese for a lasagna-like version.
3. Vegetable-Packed Casserole
Add zucchini, mushrooms, or spinach for extra nutrition and flavor.
