- 2 cloves garlic, minced
- 1 can (15 oz) diced tomatoes, drained
- 1 can (15 oz) tomato sauce
- 1 cup beef broth
- 1 tbsp Worcestershire sauce
- 1 tsp dried oregano
- 1 tsp dried basil
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
- 1 1/2 cups shredded cheddar cheese, divided
For Serving:
- Optional: Fresh parsley, chopped green onions
- Suggested Accompaniments: Green salad, garlic bread
- Suggested Pairings: Red wine (e.g., Merlot), iced tea
- Suggested Aesthetic: Serve in a white ceramic baking dish
- Suggested Equipment: Large skillet, 9×13-inch baking dish, mixing bowl, knife, cutting board, measuring cups/spoons, spatula
Step-by-Step Process
- Preheat Oven: Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch white ceramic baking dish.
- Cook Beef and Vegetables: In a large skillet over medium heat, cook ground beef and onion until beef is browned and cooked through, about 5–7 minutes. Drain excess fat. Add garlic and diced bell peppers, cooking for 3–4 minutes until peppers soften.
- Prepare Filling: Stir in uncooked rice, diced tomatoes, tomato sauce, beef broth, Worcestershire sauce, oregano, basil, salt, and pepper. Bring to a simmer and cook for 2–3 minutes. Taste the filling and adjust with a pinch of salt or extra oregano for balanced flavor. Remove from heat.
- Assemble Casserole: Transfer the mixture to the prepared baking dish. Stir in 1 cup of shredded cheddar cheese. Sprinkle the remaining 1/2 cup of cheese on top.
- Bake: Cover with foil and bake for 60–65 minutes, until rice is tender and liquid is absorbed. Remove foil and bake for an additional 5–10 minutes until cheese is bubbly and golden.
- Serve: Let the casserole rest for 5 minutes. Serve warm in the white ceramic baking dish, garnished with fresh parsley or green onions, alongside green salad, garlic bread, red wine, or iced tea.
Tips for Better Stuffed Pepper Casserole
- Dice bell peppers uniformly for even cooking and texture.
- Taste the filling before baking to balance savory, tangy, and herbaceous flavors; adjust cautiously.
- Drain excess fat from the beef to prevent a greasy casserole.
- Use long-grain rice for the best texture; rinse rice beforehand to reduce stickiness.
- Present in a white ceramic baking dish to highlight the colorful peppers and bubbly cheese.
- Make ahead: Prepare filling up to 1 day in advance; store in the fridge, assemble, and bake fresh.
- For a crispier cheese topping, broil for 1–2 minutes at the end, watching closely to avoid burning.
- Enhance aesthetic: Garnish with chopped parsley or green onions in a white ceramic dish for a vibrant, homestyle look.
