These stuffed bell peppers are filled with seasoned ground beef, tender rice, tomatoes and melted cheese. The colourful pepper halves hold the filling neatly and turn sweet and tender as they bake.
Cooking the beef mixture before filling the peppers ensures that every component is properly seasoned and thoroughly cooked. Briefly pre-baking the empty peppers prevents them remaining unpleasantly firm after the filling becomes hot.
This straightforward dinner can be assembled ahead, adjusted with different meats or grains and reheated successfully. Serve the peppers alone for a complete meal or add salad, roasted vegetables or homemade dinner rolls.

Ingredient Notes
Bell peppers: Red, orange and yellow peppers are sweeter, while green peppers have a stronger, slightly bitter flavour. Choose peppers that are firm and large enough to hold the filling.
Ground beef: Lean ground beef provides savoury flavour without producing excessive grease. Drain the skillet when necessary.
Rice: Use fully cooked rice. Leftover chilled rice works well because the grains remain separate when folded into the filling.
Diced tomatoes: Drain them before adding so the filling does not become watery.
Tomato sauce: Some sauce is mixed into the beef and some is spread beneath the peppers to help keep them moist.
Worcestershire sauce: Adds savoury depth. Check the label if preparing a strictly gluten-free meal.
Cheese: Cheddar provides a stronger flavour, while mozzarella produces a milder, stretchier topping. A combination of both also works.
Which Bell Peppers Are Best for Stuffing?
Any bell pepper colour can be used.
Red Bell Peppers
Red peppers are mature, sweet and colourful. Their sweetness balances the savoury beef filling.
Yellow and Orange Bell Peppers
These varieties are also sweet and create a bright presentation.
Green Bell Peppers
Green peppers have a firmer texture and a more pronounced flavour. They are a classic choice for stuffed peppers but may taste less sweet.
Using several colours makes the finished dish particularly attractive for family meals and entertaining.
Choose peppers with smooth skin, firm walls and no soft spots.
Should You Cook Bell Peppers Before Stuffing Them?
Briefly pre-cooking the peppers produces a more consistently tender result.
This recipe pre-bakes the empty pepper halves for approximately 15 minutes. They continue cooking after the filling and cheese are added.
If you prefer very firm peppers, you can reduce the initial cooking time. Completely skipping this stage can leave the peppers noticeably crisp.
How to Cut Peppers for Stuffing
Wash and dry the peppers.
Cut each pepper in half lengthways through the stem. Remove the seeds and pale inner membranes.
Leaving the stem attached creates an attractive shape, but the stem should not be eaten.
Alternatively, slice off the top and stand each pepper upright. Whole upright peppers need more filling and usually require a longer baking time.
Halved peppers cook faster and are easier to serve.
How to Make Stuffed Bell Peppers
Step 1: Prepare the Oven and Dish
Preheat the oven to 375°F.
Spread ½ cup of the tomato sauce across the bottom of a 9 × 13-inch baking dish.
The sauce helps prevent sticking and provides additional moisture.
Step 2: Prepare the Peppers
Cut the peppers in half lengthways.
Remove the seeds and pale membranes.
Arrange the eight pepper halves cut-side upwards in the prepared baking dish.
Brush the exposed edges lightly with a small amount of olive oil.
Step 3: Pre-Bake the Peppers
Cover the baking dish with aluminium foil.
Bake the empty pepper halves for approximately 15 minutes.
Remove them from the oven and carefully pour away any water that has collected inside.
Step 4: Brown the Ground Beef
While the peppers bake, heat the remaining olive oil in a large skillet over medium-high heat.
Add the ground beef and chopped onion.
Cook for approximately 6–8 minutes, breaking the beef into small pieces, until the meat is browned and the onion is soft.
Drain excess fat when necessary.
Step 5: Season the Filling
Add the minced garlic, Italian seasoning, paprika, salt and black pepper.
Cook for approximately 30 seconds, stirring continuously.
Add the tomato paste and cook for another minute. Briefly cooking tomato paste deepens its flavour.
Step 6: Add the Tomatoes and Sauce
Stir in the drained diced tomatoes, remaining ½ cup tomato sauce and Worcestershire sauce.
Simmer for approximately 3–4 minutes, until the mixture thickens slightly.
Step 7: Add the Rice and Cheese
Reduce the heat to low.
Fold the cooked rice into the beef mixture.
Add ½ cup of the shredded cheese and stir until it begins to melt.
Taste the filling and adjust the seasoning before stuffing the peppers.
Step 8: Fill the Peppers
Divide the beef-and-rice mixture evenly between the eight pepper halves.
Press the filling gently into each pepper without compacting it excessively.
Sprinkle the remaining cup of cheese over the tops.
Step 9: Bake
Cover the dish loosely with aluminium foil.
Bake at 375°F for 15 minutes.
Remove the foil and continue baking for another 10–15 minutes, until the cheese has melted and the peppers are tender.
If desired, broil for approximately one minute to create golden spots on the cheese.
Step 10: Rest and Serve
Allow the stuffed peppers to rest for approximately five minutes.
Garnish with chopped parsley and serve with some of the tomato sauce from the bottom of the dish.
Tips for Perfect Stuffed Peppers
Choose Similarly Sized Peppers
Peppers of a similar size cook at approximately the same rate and hold similar amounts of filling.
Drain the Tomatoes
Excess tomato liquid can make the filling watery and collect inside the peppers.
Use Cooked Rice
Raw rice needs additional liquid and cooking time. It should not be substituted directly in this recipe.
Pre-Cook the Peppers
The filling is already cooked before assembly. Pre-baking gives the peppers enough time to become tender.
Season the Filling Before Stuffing
Taste the cooked beef-and-rice mixture before dividing it between the peppers.
Avoid Overfilling
Mound the filling gently but leave enough room for the cheese topping.
Cover During the First Baking Stage
Foil traps moisture and helps the peppers soften without drying out the filling.
How Do You Know When Stuffed Peppers Are Done?
The peppers are ready when:
- The cheese is completely melted.
- The filling is bubbling gently around the edges.
- A small knife enters the pepper wall easily.
- The centre of the filling is thoroughly hot.
- The peppers are tender but still hold their shape.
The beef is fully cooked before assembly, so the final baking stage primarily heats the filling and softens the peppers.
Why Are My Stuffed Peppers Watery?
Common causes include:
- Not draining canned tomatoes.
- Using very wet freshly cooked rice.
- Adding excessive tomato sauce.
- Not pouring water out after pre-baking.
- Using frozen vegetables without removing excess moisture.
- Covering the peppers for the complete baking time.
Some liquid from the peppers is normal. Allow the dish to rest before serving.
Why Are My Peppers Still Hard?
The peppers may be particularly thick, the pre-baking stage may have been shortened or the casserole may not have remained covered long enough.
Cover the dish and continue baking in 5–10-minute intervals until the peppers reach the desired tenderness.
Why Is the Filling Dry?
A dry filling can result from:
- Using very lean beef without enough sauce.
- Omitting the diced tomatoes.
- Adding too much rice.
- Baking the peppers uncovered for too long.
- Reheating without additional sauce.
- Overcooking the beef during the initial browning stage.
Add a small amount of tomato sauce or beef broth if the mixture looks dry before stuffing.
Stuffed Bell Pepper Variations
Italian Stuffed Peppers
Use mild Italian sausage instead of ground beef.
Add Italian seasoning, mozzarella and parmesan.
Mexican-Inspired Stuffed Peppers
Replace the Italian seasoning with taco seasoning.
Add black beans and corn, then top with cheddar or a Mexican cheese blend.
Serve with salsa, avocado and sour cream.
Turkey Stuffed Peppers
Replace the beef with ground turkey.
Because turkey is lean, add a small amount of additional olive oil if the filling appears dry.
Chicken Stuffed Peppers
Use ground chicken and season it generously. Cook it until it reaches 165°F before filling the peppers.
Vegetarian Stuffed Peppers
Replace the beef with a combination of black beans, cooked lentils, mushrooms or additional vegetables.
Quinoa Stuffed Peppers
Replace the rice with an equal quantity of cooked quinoa.
Cauliflower Rice Stuffed Peppers
Use cooked cauliflower rice for a lower-carbohydrate variation.
Cook away its excess moisture before adding it to the filling.
Spicy Stuffed Peppers
Add crushed red pepper flakes, cayenne pepper or diced jalapeño to the beef mixture.
Pizza Stuffed Peppers
Use marinara sauce, mozzarella and Italian sausage. Add sliced olives or pepperoni when desired.
What to Serve With Stuffed Peppers
Stuffed peppers already contain protein, vegetables and rice, but you can serve them with:
- A simple green salad.
- Garlic bread.
- Homemade dinner rolls.
- Roasted green beans.
- Steamed broccoli.
- Garlic parmesan Brussels sprouts.
- Air fryer zucchini fries.
- Honey-glazed carrots.
- Roasted asparagus.
- Creamy mashed potatoes.
Can You Make Stuffed Peppers Ahead?
Yes.
Prepare and pre-bake the pepper halves.
Cook the filling and allow it to cool.
Fill the peppers, add the cheese and cover the dish tightly.
Refrigerate for up to 24 hours.
Remove the dish from the refrigerator while the oven preheats. Bake the peppers covered for approximately 20–25 minutes, then uncover and continue cooking until the cheese melts and the centres are thoroughly hot.
Cold assembled peppers may require approximately 10 additional minutes.
How to Store Leftovers
Allow the stuffed peppers to cool promptly.
Transfer them to an airtight container or cover the baking dish securely.
Refrigerate within two hours and use within 3–4 days.
Store the peppers in a single layer when possible to protect the cheese topping.
How to Reheat Stuffed Peppers
In the Oven
Place the peppers in an oven-safe baking dish.
Add a small spoonful of tomato sauce or water to the bottom.
Cover and reheat at 350°F for approximately 15–20 minutes, or until thoroughly hot.
In the Microwave
Place one pepper half on a microwave-safe plate.
Cover loosely and heat in short intervals until the centre is hot.
Heating time will depend on the size and density of the filling.
In the Air Fryer
Place one or two pepper halves in the air-fryer basket.
Reheat at approximately 325°F until hot. Check frequently so the cheese does not become overly brown.
Can You Freeze Stuffed Peppers?
Yes.
Allow the cooked peppers to cool completely.
Wrap each pepper individually or arrange them in a freezer-safe container.
Freeze for up to three months.
Thaw overnight in the refrigerator before reheating.
The peppers may become slightly softer after freezing, but the flavour should remain good.
For the best appearance, add a small quantity of fresh cheese during reheating.
Frequently Asked Questions
Should I boil peppers before stuffing them?
Boiling is not necessary. Pre-baking the pepper halves for approximately 15 minutes softens them without making them waterlogged.
Can I use uncooked rice?
No. Use fully cooked rice in this recipe. Raw rice requires additional liquid and a different baking time.
Can I use leftover rice?
Yes. Leftover rice is ideal as long as it was refrigerated promptly and stored safely.
Can I make stuffed peppers without rice?
Yes. Replace the rice with cooked quinoa, cauliflower rice, lentils or additional vegetables.
Can I use ground turkey?
Yes. Cook the turkey thoroughly before filling the peppers. Add a little olive oil if the mixture appears dry.
Which colour pepper is sweetest?
Red peppers are generally the sweetest, followed by orange and yellow peppers. Green peppers have a stronger, slightly bitter flavour.
Can I use whole peppers instead of halves?
Yes. Remove the tops and seeds, then stand the whole peppers upright in the baking dish. They will require more filling and may need additional baking time.
Are stuffed bell peppers gluten-free?
The main ingredients can be gluten-free, but check the Worcestershire sauce, tomato products, seasonings and cheese labels if preparing the meal for someone with coeliac disease.
How many stuffed peppers does this recipe make?
The recipe uses four peppers cut into halves, producing eight portions.
Can I prepare them without cheese?
Yes. Omit the cheese or use a suitable dairy-free alternative. The filling will still hold together.
