• 2 cloves garlic, minced: Boosts flavor with aromatic warmth.
• 1 can (15 oz) diced tomatoes, drained: Adds tangy, juicy notes without excess liquid.
• 1 cup (240ml) beef or chicken broth: Keeps the casserole moist and infuses flavor.
• 1 tbsp tomato paste: Intensifies tomato flavor for a rich base.
• 1 tsp Italian seasoning: Blends herbs for a balanced, savory taste.
• ½ tsp smoked paprika: Adds a subtle smoky depth.
• 1 ½ cups (150g) shredded cheddar cheese, divided: Melts into gooey, golden perfection.
• 1 tbsp olive oil: For sautéing, ensuring even cooking.

Step-by-Step Instructions

Save

1. Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish to prevent sticking.
2. Cook the rice. In a medium saucepan, cook rice according to package instructions, using broth instead of water for extra flavor. Set aside.
3. Sauté the beef and veggies. Heat olive oil in a large skillet over medium heat. Add ground beef, breaking it apart, and cook until browned, about 5-7 minutes. Drain excess fat. Add onion, garlic, and diced bell peppers, cooking until softened, about 5 minutes.
4. Add seasonings and tomatoes. Stir in tomato paste, diced tomatoes, Italian seasoning, smoked paprika, salt, and pepper. Cook for 2 minutes until fragrant, letting the flavors meld.
5. Combine ingredients. In a large bowl, mix the cooked rice, beef-vegetable mixture, and 1 cup of shredded cheese. Stir until evenly combined.
6. Assemble the casserole. Spread the mixture evenly in the prepared baking dish. Sprinkle the remaining ½ cup cheese on top for a golden, bubbly finish.
7. Bake. Cover with foil and bake for 25 minutes. Remove foil and bake for an additional 10-15 minutes, until the cheese is melted and slightly browned.
8. Garnish and serve. Let the casserole rest for 5 minutes, then sprinkle with fresh parsley for a pop of color.

Tips for Success

• Rinse the rice: This prevents a gummy texture and ensures fluffy grains.
• Don’t overcook the peppers: Sauté until just softened to maintain their vibrant crunch.
• Use lean beef: This reduces grease and keeps the casserole light.
• Check cheese browning: If browning too quickly, cover loosely with foil during the final bake.
• Let it rest: Resting before serving helps the casserole set for easier slicing.

Serving Suggestions

Save

Storage Tips

• Room temperature: Keep covered at room temperature for up to 2 hours after baking.
• Refrigeration: Store in an airtight container in the fridge for up to 4 days. Reheat in the oven or microwave until warmed through.

FAQs

Can I use ground turkey instead of beef?
Yes, ground turkey works well and makes a lighter dish. Adjust seasoning to taste.

Can I make this vegetarian?
Swap beef for lentils or plant-based meat and use vegetable broth for a hearty vegetarian version.

What other cheeses can I use?
Try mozzarella for stretchy texture or Monterey Jack for a milder flavor.

Can I prep this casserole ahead?
Assemble up to a day in advance, refrigerate, and bake when ready. Add 5-10 minutes to baking time.

Why is my casserole watery?
Ensure tomatoes are well-drained and don’t skip rinsing the rice to avoid excess liquid.
