Instructions

1. Prepare the oven

Preheat your oven to 375°F (190°C). Lightly grease a 9 x 13-inch baking dish and set it aside.

2. Brown the beef

Heat the olive oil in a large skillet over medium-high heat.

Add the ground beef and cook for about 5–7 minutes, breaking it into small pieces as it browns. Once there’s no pink left, drain away any excess fat if necessary.

3. Add the vegetables

Stir in the diced onion along with the red, green, and yellow bell peppers.

Cook everything together for about 4–5 minutes. You want the vegetables to soften slightly while still keeping some texture.

At this point, the skillet should already smell wonderfully savory and sweet.

4. Add the garlic

Stir in the minced garlic and cook for around 30 seconds.

You’ll know it’s ready as soon as that warm garlic aroma starts filling the kitchen.

5. Build the tomato sauce

Add the tomato paste, diced tomatoes, tomato sauce, and beef broth.

Stir well so the tomato paste melts into the sauce and everything becomes rich and evenly combined.

6. Season everything

Sprinkle in the smoked paprika, Italian seasoning, cumin, garlic powder, salt, and black pepper.

Lower the heat slightly and allow the mixture to simmer for 5–7 minutes.

The sauce should thicken a little and cling nicely to the beef and vegetables.

7. Stir in the rice

Add the cooked rice directly to the skillet.

Gently stir until every grain is coated with the beefy tomato sauce and the colorful peppers are evenly scattered throughout.

8. Start layering

Spread half of the beef and rice mixture into your prepared baking dish.

Sprinkle half of the cheddar cheese and half of the mozzarella over the top.

9. Add the second layer

Spoon the remaining beef and rice mixture over the cheese.

Finish with the rest of the cheddar and mozzarella, spreading it evenly from edge to edge.

10. Bake

Place the casserole in the oven and bake uncovered for 20–25 minutes.

You’re looking for a hot, bubbling casserole with beautifully melted cheese covering the surface.

11. Make the top golden

For an extra tempting finish, switch the oven to broil for 1–2 minutes.

Keep a close eye on it — cheese can go from golden and bubbly to too dark very quickly.

12. Rest and serve

Remove the casserole from the oven and let it rest for about 5 minutes.

This gives everything a chance to settle and makes serving much easier.

Sprinkle fresh chopped parsley over the top just before bringing it to the table.

Presentation

This casserole already looks inviting with its colorful peppers and golden melted cheese, so it doesn’t need much decoration.

A generous sprinkle of fresh parsley gives it a bright finishing touch. You can also serve each portion with a little extra shredded cheese or freshly cracked black pepper.

For a balanced meal, pair it with a crisp green salad, roasted vegetables, or warm bread for soaking up any tomato sauce left on the plate.

If you’re serving it straight from the baking dish, place the casserole in the center of the table while it’s still warm and bubbling. That cozy, family-style presentation suits this recipe perfectly.
