- 1 can (14.5 oz / 411 g) diced tomatoes, with juice
- 1 cup (240 ml) beef broth
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tsp paprika
- 1/2 tsp dried thyme
- 1/2 tsp dried oregano
- 1/2 tsp sugar (optional)
- 1/4 tsp crushed red pepper flakes (optional)
- 1 cup cooked rice, egg noodles, or cubed cooked potatoes (optional)
For the Cheese and Topping:
- 2 cups (200 g) shredded cheddar cheese
- 1/2 cup (60 g) breadcrumbs (optional)
- 2 tbsp butter, melted (if using breadcrumbs)

Instructions
Step 1: Preheat Oven and Prepare Dish
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish thoroughly with butter or non-stick spray. Set aside while you prepare the beef mixture.
Step 2: Cook the Ground Beef
Place a large skillet over medium-high heat. Add the ground beef and break it into small pieces with a wooden spoon. Cook for 6–8 minutes, stirring frequently, until no pink remains and the beef is fully browned. Drain excess fat carefully into a heatproof container to prevent a greasy casserole.
Step 3: Sauté Onions and Garlic
In the same skillet, add the finely chopped onion. Sauté for 2–3 minutes until translucent and fragrant. Add the minced garlic and cook for an additional 1-2 minutes, stirring constantly to prevent burning.
Step 4: Cook the Bell Peppers
Add the diced red and green bell peppers to the skillet. Continue cooking for 3–4 minutes until the peppers are slightly softened but still retain some texture. Stir frequently to ensure even cooking.
Step 5: Combine Beef and Vegetables
Return the cooked beef to the skillet if removed. Stir to combine with the sautéed onions, garlic, and bell peppers.
Step 6: Add Seasonings and Liquids
Pour in the diced tomatoes with juice and beef broth. Add salt, black pepper, paprika, thyme, oregano, sugar, and red pepper flakes. If using, add Worcestershire sauce, soy sauce, smoked paprika, or cayenne pepper. Stir well to incorporate all ingredients.
Step 7: Simmer the Mixture
Reduce the heat to medium-low and let the mixture simmer for 5–10 minutes, stirring occasionally. This allows the flavors to meld and the liquid to reduce slightly, creating a thicker, richer base.
Step 8: Add Optional Hearty Ingredients
If desired, fold in cooked rice, egg noodles, or cubed cooked potatoes. Mix until all ingredients are evenly distributed. Taste the mixture and adjust seasonings as needed.
Step 9: Transfer to Baking Dish
Pour the beef and vegetable mixture into the prepared baking dish. Use a spatula to spread it evenly, ensuring that the mixture reaches all corners of the dish.
Step 10: Add Cheese Topping
Sprinkle the shredded cheddar cheese evenly over the top of the mixture. Make sure the cheese covers the entire surface for even melting.
Step 11: Add Breadcrumb Topping (Optional)
If using breadcrumbs, combine them with melted butter in a small bowl. Sprinkle the breadcrumb mixture evenly over the cheese layer. This will create a golden, crunchy topping when baked.
Step 12: Bake the Casserole
Place the baking dish in the preheated oven. Bake for 20–25 minutes, until the cheese is melted, bubbly, and lightly golden. If using breadcrumbs, check that the topping is lightly browned but not burned.
Step 13: Rest and Garnish
Remove the casserole from the oven and allow it to rest for 5–10 minutes. This helps the flavors settle and makes it easier to serve. Garnish with freshly chopped parsley if desired.
Step 14: Serve
Cut the casserole into squares and serve warm. Pair with a fresh salad, steamed vegetables, or crusty bread for a complete meal.
Additional Notes
- Vegetable Variations: You can substitute bell peppers with zucchini, mushrooms, or carrots.
- Cheese Options: Mix cheddar with mozzarella or Monterey Jack for a gooier texture.
- Spicy Version: Add more red pepper flakes or a chopped jalapeño for heat.
- Make-Ahead: Assemble the casserole in advance and refrigerate. Bake for 25–30 minutes before serving.
- Freezer-Friendly: Freeze before baking in a tightly covered dish for up to 2 months. Bake directly from frozen, adding 10–15 minutes to baking time.
