Stuffed bell peppers with ground beef are hollowed-out peppers filled with a seasoned mixture of browned beef, rice, and tomatoes, then baked until tender and topped with melted cheese. They’re a complete, one-dish dinner that takes about an hour from start to finish and works well for meal prep since they reheat easily.
The first time I made stuffed bell peppers, I was cooking for my in-laws on a Sunday afternoon and wanted something that looked impressive without much fuss. I rushed the rice and used it straight off the stove, and the filling turned out watery and loose by the time the peppers came out of the oven. That mistake taught me the single biggest lesson in this recipe, and I’ll walk you through exactly what fixed it.
Since then, I’ve made this dish more than a dozen times, tweaking the ratio of rice to beef and testing different bake times to get peppers that are soft but not mushy. What makes this version different is the covered-then-uncovered baking method, which keeps the peppers from drying out while still letting the cheese on top get properly melted and golden.
This recipe is for anyone who wants a filling, protein-packed dinner using basic pantry ingredients and about 10 minutes of hands-on prep. No special equipment or advanced techniques required, just a skillet, a baking dish, and an oven.
It also holds up well as leftovers, which is one of the reasons I keep coming back to it. The peppers stay intact instead of collapsing, and the filling actually tastes better the next day once the seasoning has had time to settle in.

Before You Get Started
- Use day-old rice, not fresh. In my testing, rice cooked the same day releases extra moisture into the filling as it sits, which is exactly what made my first batch watery. Rice made a day ahead and refrigerated holds its texture much better.
- Choose peppers that stand upright on their own. Bell peppers with a flat bottom sit flat in the baking dish without tipping. If yours are rounded, slice a thin sliver off the bottom (without cutting through) so they stay stable while baking.
- Ground beef with 85% lean works best. Anything leaner tends to taste dry once baked, while fattier blends leave excess grease pooling in the peppers. Drain the fat after browning either way.
- Don’t skip the water in the baking dish. Adding a small amount of water to the bottom of the dish creates steam that keeps the peppers from drying out or scorching on the bottom during the covered bake.
- Swap the rice for cooked quinoa or cauliflower rice if you want a lighter version. Both work, though cauliflower rice will make the filling slightly softer since it holds more moisture.
- Taste the filling before stuffing the peppers. Since the peppers themselves are unseasoned, this is your only chance to adjust salt and seasoning before everything goes into the oven.
- Watch for the beef to release a deep, browned smell before adding the next ingredient. If it still smells mostly like raw meat, give it another minute or two before moving on to the rice and tomatoes.
Ingredients
- 6 large bell peppers (any color), tops sliced off, seeds and membranes removed
- 1 tablespoon olive oil
- 1 small yellow onion, diced
- 2 garlic cloves, minced
- 1 pound (450g) ground beef, 85% lean
- 1 cup cooked white rice (preferably day-old)
- 1 can (14.5 oz) diced tomatoes, drained
- ½ cup tomato sauce
- 1 teaspoon Italian seasoning
- ½ teaspoon salt, plus more to taste
- ¼ teaspoon black pepper
- 1 cup shredded mozzarella or cheddar cheese
- ¼ cup water (for the baking dish)
- Fresh parsley or basil, chopped, for garnish (optional)
Instructions
Step 1: Prep the Bell Peppers
Preheat the oven to 375°F (190°C). Slice the top off each bell pepper, about half an inch down, and scoop out the seeds and membranes with a spoon.
If a pepper wobbles when you stand it up, slice a thin piece off the bottom to create a flat base, being careful not to cut all the way through (the first time I skipped this step, two peppers tipped over mid-bake and spilled filling into the dish).
Step 2: Cook the Beef and Aromatics
Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook for 4 minutes, stirring occasionally, until soft and translucent.
Add the minced garlic and cook for 1 minute until fragrant. Next, add the ground beef, breaking it apart with a spatula, and cook for 5 minutes until fully browned with no pink remaining. Drain any excess fat from the skillet.
You’ll know the beef is ready when it stops sizzling loudly and starts to smell rich and toasty rather than raw. That shift in smell and sound is a more reliable cue than the clock, especially if your stove runs hotter or cooler than average.
Step 3: Build the Filling
Stir the cooked rice, drained diced tomatoes, tomato sauce, Italian seasoning, salt, and pepper into the beef mixture. Simmer for 4 minutes, stirring occasionally, until the mixture thickens slightly and no longer looks watery.
In my testing, this simmering step is what separates a filling that holds together from one that turns soupy once it’s baked inside the pepper. Taste and adjust the seasoning here, since this is your last chance before assembly.
Step 4: Stuff the Peppers
Spoon the beef and rice mixture into each hollowed pepper, packing it gently as you go so there are no large air pockets. Mound the filling slightly above the rim of each pepper.
Arrange the stuffed peppers upright in a baking dish and pour ¼ cup of water into the bottom of the dish, around the peppers, not over them.
Step 5: Bake the Peppers
Cover the baking dish tightly with foil and bake for 20 minutes. This traps steam and keeps the pepper walls from drying out while the inside cooks through.
Remove the foil, sprinkle the shredded cheese evenly over each pepper, and bake uncovered for 5 to10 minutes more, until the cheese is melted and the peppers are tender when pierced with a fork (I learned to check with a fork after a batch where the peppers looked done on top but were still firm at the base).
Step 6: Rest and Serve
Let the peppers rest for 5 minutes before serving. This gives the filling time to firm up slightly, which makes it much easier to cut into and keeps the first bite from being scalding hot.
Garnish with chopped parsley or basil if you like, then serve warm.
How To Make Stuffed Bell Peppers (Quick Reference)
- Preheat the oven to 375°F (190°C) and hollow out 6 bell peppers.
- Sauté onion 4 minutes, then garlic 1 minute.
- Brown ground beef 5 minutes drain fat.
- Stir in rice, tomatoes, tomato sauce, and seasoning; simmer for 4 minutes.
- Stuff peppers with the filling and stand them in a dish with ¼ cup water.
- Bake covered for 20 minutes, then uncovered with cheese 5–10 minutes.
- Rest 5 minutes, garnish, and serve.
Tips for Best Results
- Let the filling cool slightly before stuffing if you’re short on peppers and need to spoon it in carefully. Piping-hot filling can make thin pepper walls harder to handle without tearing.
- Use a mix of bell pepper colors (red, yellow, orange) for a naturally sweeter flavor, since red and yellow peppers are less bitter than green ones when baked.
- Don’t overfill the skillet when browning the beef. In my early attempts, crowding the pan meant the beef steamed instead of browning, which left the filling pale and less flavorful.
- Check doneness with a fork, not just a timer. Oven performance varies, and I’ve had peppers need an extra 5 minutes on days I used thicker-walled peppers.
- Freeze extras before baking, not after, for the best texture. Assembled, unbaked stuffed peppers freeze well and can go straight from freezer to oven with about 15 extra minutes of bake time.
- Line the baking dish with a bit of extra tomato sauce if you like a saucier result. I started doing this after noticing the bottoms of the peppers tasted a little plain compared to the filling on top.

Storage & Reheating
- Refrigerator: Store cooled stuffed peppers in an airtight container for up to 4 days.
- Freezer: Wrap baked peppers individually and freeze for up to 3 months.
- Reheating from the fridge: Microwave on high for 2 to 3 minutes, or bake covered at 350°F (175°C) for 15 minutes.
- Reheating from frozen: Thaw overnight in the refrigerator, then reheat using either method above; add 5 extra minutes if reheating straight from frozen without thawing.
FAQs
Do you have to cook the rice before stuffing the peppers?
Yes, use fully cooked rice. Raw rice won’t have enough time or liquid to cook through during baking, and it will stay hard even after the peppers are tender. Day-old cooked rice works best for a firmer filling.
Why are my stuffed peppers watery?
Watery filling usually comes from using freshly cooked rice or skipping the simmer step that thickens the beef and tomato mixture. Draining the diced tomatoes and simmering the filling for a few minutes before stuffing helps prevent this.
Do you need to boil the peppers before stuffing them?
No, boiling isn’t necessary with this method. Baking the peppers covered for 30 minutes with a bit of water in the dish is enough to make them tender without a separate boiling step.
Can you make stuffed bell peppers ahead of time?
Yes. Assemble the peppers up to a day ahead, cover, and refrigerate unbaked. When ready to cook, bake as directed, adding about 5 extra minutes since the dish will start out cold.
What sides go well with stuffed bell peppers?
A simple green salad, garlic bread, or steamed vegetables all pair well since the peppers are already a complete meal with protein, grain, and vegetables. Light, fresh sides balance the richness of the beef and cheese.
