Ingredients (Serves 4–6)
For the Casserole:
- 1 pound ground beef (80/20 or 85/15): A slightly fatty blend ensures juicy, flavorful results. Ground turkey or chicken can be substituted for a lighter option.
- 1 medium yellow or white onion: Diced finely to add a sweet, savory backbone to the dish.
- 1 green bell pepper: Diced into bite-sized pieces for a slightly earthy, mildly sweet flavor.
- 1 red bell pepper: Diced to add vibrant color and a touch of sweetness. Feel free to mix in yellow or orange peppers for variety.
- 1 (14.5 oz) can diced tomatoes: Fire-roasted or regular diced tomatoes add a tangy, juicy element. Do not drain, as the liquid enhances the dish’s texture.
- 1 cup cooked white rice: Long-grain rice like jasmine or basmati works well. Brown rice or quinoa can be used for a nuttier flavor or added nutrition.
- 1 cup shredded cheddar cheese: Sharp cheddar provides bold flavor, but a Mexican blend, mozzarella, or pepper jack can add a fun twist.
- 1 teaspoon garlic powder: Adds a subtle, savory depth without the need for fresh garlic.
- Kosher salt and freshly ground black pepper: Adjust to taste to enhance the dish’s flavors.
Optional Add-Ins:
- 1 teaspoon smoked paprika or chili powder: For a smoky or slightly spicy kick.
- ½ cup corn kernels or black beans: To add texture and a touch of sweetness or earthiness.
- Fresh herbs like parsley or cilantro: For a garnish that adds freshness and visual appeal.
Equipment Needed
- A large skillet (preferably cast iron or nonstick) for cooking the beef and vegetables
- A 9×13-inch baking dish, greased
- A wooden spoon or spatula for stirring
- An oven preheated to 350°F (175°C)
- Measuring cups and spoons
- A colander for draining (if needed)
Preparation Instructions
- Prepare the Oven and Baking Dish
Preheat your oven to 350°F (175°C, or 160°C for fan ovens). Lightly grease a 9×13-inch baking dish with cooking spray, olive oil, or butter to prevent sticking. This ensures easy serving and cleanup. - Cook the Ground Beef
Heat a large skillet over medium heat. Add the ground beef, breaking it up with a wooden spoon or spatula. Cook for 6–8 minutes, stirring occasionally, until the beef is browned and no longer pink. If using a fattier blend, drain excess grease from the skillet using a colander or carefully tilt the pan to remove the fat, leaving about a tablespoon for flavor. Set the beef aside in the skillet or a separate bowl. - Sauté the Vegetables
In the same skillet, add the diced onion, green bell pepper, and red bell pepper. Cook over medium heat for 5–7 minutes, stirring occasionally, until the vegetables are tender and the onions are translucent. The peppers should soften but retain a slight bite for texture. If you like a bit more caramelization, cook for an additional 2–3 minutes until the edges of the peppers begin to brown slightly. - Combine the Filling
Return the cooked ground beef to the skillet with the vegetables. Stir in the can of diced tomatoes (including the liquid), cooked rice, garlic powder, and a generous pinch of salt and black pepper. For extra flavor, consider adding optional spices like smoked paprika or chili powder at this stage. Stir well to combine and let the mixture simmer for 4–5 minutes, allowing the flavors to meld and the tomatoes to release their juices, creating a cohesive filling. Taste and adjust seasoning as needed. - Assemble the Casserole
Transfer the beef and vegetable mixture to the greased 9×13-inch baking dish, spreading it evenly with a spatula. Sprinkle the shredded cheddar cheese evenly over the top, ensuring every bite has a cheesy, golden finish. For a cheesier casserole, feel free to add an extra ¼–½ cup of cheese. - Bake to Perfection
Place the baking dish in the preheated oven and bake for 25–30 minutes, or until the cheese is melted, bubbly, and slightly golden in spots. The casserole should be heated through, with the flavors fully melded. If you prefer a more browned cheese topping, switch the oven to broil for the final 1–2 minutes, watching closely to avoid burning. - Serve and Enjoy
Remove the casserole from the oven and let it rest for 5 minutes to set, making it easier to serve. Spoon generous portions onto plates, ensuring each serving has a mix of the hearty filling and cheesy topping. Garnish with fresh parsley or cilantro for a pop of color, if desired. Serve with your favorite sides, such as a crisp green salad, garlic bread, or steamed broccoli, to round out the meal.
Serving Suggestions
- Classic Pairings: Serve over a bed of fluffy mashed potatoes or alongside crusty garlic bread to soak up the flavorful juices. A side of roasted or steamed vegetables, like zucchini or green beans, adds a fresh contrast.
- Salad Option: Pair with a simple garden salad dressed with a tangy vinaigrette to balance the richness of the casserole.
- Drinks: Enjoy with a refreshing iced tea, a light red wine like Merlot, or a sparkling water with a lemon twist for a non-alcoholic option.
- Leftovers: This casserole reheats beautifully, making it great for meal prep. Store leftovers in an airtight container in the fridge for up to 3 days and reheat in the microwave or oven until warmed through.
Tips for Success
- Rice Preparation: Use day-old rice for the best texture, as it absorbs the flavors without becoming mushy. If cooking rice fresh, let it cool slightly before adding to the mixture.
- Pepper Variations: Mix and match bell peppers (green, red, yellow, or orange) to add color and flavor variety. For a spicier twist, include a diced jalapeño or a pinch of red pepper flakes.
- Cheese Options: Swap cheddar for mozzarella, Monterey Jack, or a Mexican blend for different flavor profiles. For a gourmet touch, sprinkle a little Parmesan over the top before baking.
- Make Ahead: Assemble the casserole up to a day in advance, cover tightly, and refrigerate. When ready to bake, let it sit at room temperature for 20 minutes, then bake as directed, adding 5–10 minutes if needed.
- Freezing: Freeze the unbaked or baked casserole in a freezer-safe dish for up to 3 months. Thaw overnight in the fridge before baking or reheating. If baking from frozen, cover with foil and add 15–20 minutes to the baking time.
- Flavor Boosters: Add a tablespoon of Worcestershire sauce or a splash of soy sauce to the beef mixture for extra umami. Fresh herbs like thyme or oregano can also enhance the dish’s aroma.
