Ingredients
- 1 pound ground beef (85/15 lean-to-fat ratio recommended)
- 1 small yellow onion, finely diced
- 4 large bell peppers (mixed red, yellow, and green), chopped
- 2 cloves garlic, minced
- 1 cup long-grain white rice (uncooked)
- 2 cups low-sodium beef broth
- 1 can (14.5 oz) diced tomatoes, drained (reserve 1/4 cup juice)
- 1 tablespoon Worcestershire sauce
- 1 teaspoon Italian seasoning
- 1/2 teaspoon smoked paprika
- Salt and freshly cracked black pepper to taste
- 1 1/2 cups sharp cheddar cheese, freshly grated
- 1/2 cup mozzarella cheese
Instructions
1. Preheat oven to 375°F and grease a 9×13-inch baking dish. Prepare the bell peppers by coring, deseeding, and dicing into bite-sized pieces.
2. Heat a large skillet over medium-high heat. Add ground beef and onion together, cooking for 6–8 minutes until beef is browned and onions softened. Stir in garlic during the last minute.
3. Add uncooked rice to the skillet and stir to coat in fat. Pour in beef broth, diced tomatoes (reserving 1/4 cup juice), Worcestershire sauce, Italian seasoning, and smoked paprika. Season with salt and pepper.
4. Fold in chopped bell peppers and stir to evenly combine. Transfer mixture to prepared baking dish and spread evenly.
5. Cover tightly with aluminum foil and bake for 45 minutes. Remove foil and check rice doneness. If needed, add reserved tomato juice and bake 5 minutes more.
6. Top with cheddar and mozzarella cheeses. Bake uncovered for another 10 minutes until cheese is melted and golden.
7. Let casserole rest for 5 minutes before serving to allow flavors to settle.
Notes
You can substitute ground beef with ground turkey, chicken, or plant-based crumbles for a lighter or vegetarian version.
Jasmine or basmati rice both work beautifully in this dish.
To prevent a soupy texture, be sure to let the casserole rest before serving.
Make ahead tip: Prepare the mixture a day in advance and bake when ready.
