Preparation
Step 1: Cook Beef and Veggies

- Simmer for 5–7 minutes to let flavors blend.
Step 3: Combine with Rice
- Add cooked rice to the skillet mixture and stir until evenly combined.
Step 4: Assemble the Casserole
- Preheat oven to 375°F (190°C).
- Spread half of the mixture into a greased 9×13-inch baking dish.
- Sprinkle with 1 cup mozzarella cheese.
- Add the rest of the mixture and top with remaining mozzarella and cheddar.
Step 5: Bake
- Bake uncovered for 25–30 minutes, until hot and bubbly with melted golden cheese.
Step 6: Serve
- Let casserole rest 5 minutes before serving. Garnish with fresh parsley if desired.
Variations
- Low-Carb Option: Replace rice with cauliflower rice.
- Mexican Style: Add taco seasoning and use pepper jack cheese. Serve with sour cream and salsa.
- Vegetarian Version: Skip beef and double the peppers, mushrooms, or zucchini.
- Cheesy Twist: Mix in cream cheese for a creamier texture.
Cooking Notes
- Cook rice slightly firm so it doesn’t get mushy when baked.

Serving Suggestions
- Pair with a green salad or roasted vegetables.
- Serve with garlic bread or dinner rolls to soak up the sauce.
- Add a dollop of sour cream or Greek yogurt on top for creaminess.
