Introduction
This Cheesy Ground Beef and Bell Pepper Casserole is a delicious, hearty, and comforting one-dish meal inspired by the beautiful casserole in your photo. It combines seasoned ground beef, colorful bell peppers, tomatoes, onions, herbs, and plenty of melted cheese.
The beef is cooked until nicely browned and flavorful, while the peppers add sweetness, color, and a little crunch.

- 2 tablespoons tomato paste
- ½ cup beef broth or water
- 1 teaspoon paprika
- 1 teaspoon cumin
- 1 teaspoon dried oregano
- ½ teaspoon chili powder
- ½ teaspoon black pepper

- ½ teaspoon onion powder
- 1 teaspoon Italian seasoning
- 1 tablespoon fresh parsley, chopped
For the Cheese Topping
- 200 g shredded mozzarella

🧅 Step 1: Prepare the Vegetables
Wash the bell peppers thoroughly.
Remove the seeds and white membranes.
Cut the red, green, and yellow peppers into small pieces.
Dice the onion.
Mince the garlic.
Using several colors of bell pepper makes the finished casserole look beautiful and also gives it a mixture of slightly different flavors.
🥩 Step 2: Brown the Ground Beef
Heat a large skillet over medium-high heat.
Add the olive oil.
Place the ground beef into the hot skillet.
Break it apart using a wooden spoon or spatula.
Cook for approximately 6–8 minutes, stirring occasionally, until the beef is browned and cooked through.
If there is a large amount of excess fat, carefully drain some of it.
Leave a little for flavor.
🧄 Step 3: Add Onion and Garlic
Add the diced onion to the browned beef.
Cook for approximately 3–4 minutes, stirring occasionally.
The onion should become soft and translucent.
Add the minced garlic.
Cook for another 30–60 seconds.
Be careful not to burn the garlic.
At this stage, the kitchen should already smell wonderfully savory.
🌶️ Step 4: Add the Bell Peppers
Add the chopped red, green, and yellow bell peppers.
Stir everything together.
Cook for approximately 5–7 minutes.
The peppers should soften slightly while still maintaining some texture.
You don’t want them completely mushy because they will continue cooking in the oven.
🍅 Step 5: Build the Tomato Sauce
Add the tomato paste.
Stir it into the beef and vegetables.
Cook for about one minute.
Then add the crushed tomatoes and beef broth.
Add:
- Paprika
- Cumin
- Oregano
- Chili powder
- Black pepper
- Salt
- Garlic powder
- Onion powder
- Italian seasoning
Mix thoroughly.
Bring everything to a gentle simmer.
🔥 Step 6: Simmer the Beef Mixture
Reduce the heat to medium-low.
Allow the mixture to simmer for approximately 10–15 minutes.
Stir occasionally.
The sauce should become thicker and coat the beef and vegetables.
Taste the mixture.
If necessary, adjust the seasoning.
For a sweeter sauce, you can add a tiny amount of sugar.
For more heat, add chili flakes or a little hot sauce.
For extra freshness, add chopped parsley near the end.
🧀 Step 7: Prepare the Casserole Dish
Preheat your oven to:
200°C / 400°F
Lightly grease a large oven-safe casserole dish with olive oil.
Transfer the cooked beef and pepper mixture into the dish.
Spread it evenly using a spatula.
Make sure the mixture reaches the corners and edges.
🧀 Step 8: Add the Cheese
Now comes the best part!
Sprinkle the mozzarella evenly over the beef mixture.
Add the cheddar.
Finish with Parmesan.
Try to distribute the cheese evenly so every serving gets a delicious cheesy topping.
For an attractive golden crust, sprinkle a small amount of paprika over the cheese.
🔥 Step 9: Bake
Place the casserole into the preheated oven.
Bake uncovered for approximately 15–20 minutes.
The cheese should melt completely and begin bubbling.
For an even more golden top, turn on the oven’s grill/broiler function for the final 1–3 minutes.
Watch it carefully because the cheese can brown quickly.
Remove the casserole when the top is golden and bubbling.
🌿 Step 10: Rest and Garnish
Allow the casserole to rest for about 5–10 minutes.
This gives the sauce a chance to settle and makes it easier to serve.
Sprinkle freshly chopped parsley over the top.
You can also add a few thin slices of fresh bell pepper for decoration.
Serve while warm.
🍽️ What to Serve With It
This casserole is very versatile.
🍚 With Rice
Serve it over steamed white rice, brown rice, or basmati rice.
The rice absorbs the tomato sauce and makes the meal extra filling.
🍝 With Pasta
Spoon the cheesy beef mixture over cooked pasta.
Short pasta shapes such as penne, fusilli, or shells work especially well.
🥔 With Potatoes
Serve it with roasted or mashed potatoes.
The combination of potatoes, beef, peppers, tomato sauce, and melted cheese makes a very comforting dinner.
🥖 With Bread
Warm crusty bread is one of the easiest options.
Use the bread to scoop up the flavorful sauce.
🥦 Add More Vegetables
You can easily increase the vegetables in this casserole.
Try adding:
- Zucchini
- Mushrooms
- Corn
- Carrots
- Spinach
- Broccoli
- Green beans
Mushrooms are particularly delicious with ground beef.
Simply slice them and cook them with the peppers.
🌶️ Spicy Version
If you enjoy spicy food, make a hotter version by adding:
- ½ teaspoon cayenne pepper
- 1 teaspoon chili flakes
- Fresh chopped chili
- Hot paprika
- A little hot sauce
Add the spicy ingredients gradually and taste as you go.
🧀 Extra-Cheesy Version
For an extremely cheesy casserole, use a combination of:
- Mozzarella
- Cheddar
- Parmesan
- Monterey Jack
Mozzarella gives you the stretchy melted cheese.
Cheddar provides a stronger flavor.
Parmesan adds a salty, nutty taste.
The combination creates a rich and flavorful topping.
🥩 Alternative Meat Options
Ground beef is perfect for this recipe, but you can also use:
Ground Turkey
A mild alternative that works well with the peppers and tomato sauce.
Ground Chicken
Use the same seasonings and make sure the chicken is cooked thoroughly.
Beef and Lamb
A mixture of ground beef and lamb gives the casserole a richer flavor.
🍳 Breakfast Variation
You can even transform leftovers into a breakfast.
Warm a portion of the beef and pepper mixture in a skillet.
Make a small space in the mixture and add an egg.
Cover the pan and cook until the egg reaches your preferred level of doneness.
Add a little cheese on top.
Serve with toast.
🥑 Fresh Toppings
After baking, you can add fresh toppings for contrast.
Try:
- Chopped parsley
- Cilantro
- Green onions
- Avocado
- Fresh tomatoes
- Sour cream
- Plain yogurt
A spoonful of cool yogurt or sour cream works especially well with the warm, spicy beef.
👨🍳 Chef’s Tips
Don’t skip browning the beef
Browning creates deeper flavor than simply boiling the meat in tomato sauce.
Cook the peppers before baking
This allows them to soften while still retaining some texture.
Don’t make the sauce too watery
A thick beef mixture works better in a casserole because the cheese stays on top.
Use freshly shredded cheese
Freshly shredded cheese generally melts more smoothly.
Rest before serving
Five to ten minutes makes the casserole easier to portion.
Don’t burn the cheese
If using the grill/broiler, stay nearby and watch carefully.
🥘 Make-Ahead Method
This casserole is excellent for preparing ahead of time.
Cook the beef, vegetables, and sauce.
Transfer the mixture to the baking dish.
Allow it to cool appropriately, then cover and refrigerate.
When ready to bake, add the cheese topping and bake until thoroughly hot and bubbling.
This makes it convenient for busy days when you want dinner prepared ahead of time.
🧊 Storage
Store leftovers in an airtight container in the refrigerator.
Reheat until thoroughly hot.
You can reheat individual portions in the microwave or reheat a larger amount in the oven.
If reheating in the oven, covering the dish can help prevent the top from becoming too dry.
❄️ Freezing
The cooked beef and vegetable mixture can also be frozen.
For best results, freeze it in a suitable airtight freezer container.
Thaw it safely in the refrigerator before reheating and adding fresh cheese if desired.
