Classic Gluten Free Stuffed Peppers
Gluten free stuffed peppers are the kind of dinner that feels like a hug on a busy weeknight. They come out of the oven tender, savory, and topped with a golden cap of cheese.

Every bell pepper holds a generous mix of seasoned beef, tomato rice, and melted mozzarella. You get a complete meal in one colorful package, and no one at the table will miss the gluten.
Why These Stuffed Peppers Work
The rice soaks up the tomato sauce and beef juices as it bakes, so each bite stays moist without turning mushy. It’s that simple absorption that makes the filling taste like it simmered for hours.
The cheese on top gets a quick broil at the end, leaving the mozzarella bubbly with crisp, browned edges. That contrast between the soft pepper and the slightly chewy cheese crust is what keeps everyone going back for seconds.
Ingredients

- 4 large bell peppers (any color): choose ones with flat bottoms so they stand up straight
- 1 tbsp olive oil: for sautéing
- 1 yellow onion, diced: medium dice so it blends into the filling
- 1 lb ground beef: 85% lean keeps it moist without excess grease
- 2 garlic cloves, minced: adds depth without overpowering
- 1 cup cooked white rice: chilled or fresh; short or medium grain works best
- 1 cup tomato sauce: check that yours is labeled gluten free
- 1 tsp Italian seasoning: a dried blend of oregano, basil, thyme
- ½ tsp salt: plus more for the blanching water
- ¼ tsp black pepper
- ½ cup shredded mozzarella: part-skim melts into a nice stretchy cap
- Fresh basil and extra tomato sauce for serving: optional but brightens everything up
Variations / Substitutions
- Swap the protein: ground turkey works just as well; use the same weight and brown it the same way
- Make it low carb: replace the rice with finely riced cauliflower, and reduce the tomato sauce to ¾ cup to keep the filling from getting too wet
- Change the cheese: provolone or fontina melt beautifully and add a sharper bite
- Skip the dairy: use your favorite plant-based mozzarella shreds; they still get melty under the broiler
- Herb it up: stir a handful of chopped fresh parsley or basil into the filling for a fresher note

How to Make Gluten Free Stuffed Peppers
Step 1: Blanch the Peppers

Preheat your oven to 375°F (190°C) and bring a large pot of salted water to a boil. While the water heats, slice the tops off the 4 bell peppers and scoop out the seeds and white membranes. Drop the peppers and their tops into the boiling water and cook them for 3 minutes, just until they turn a brighter green and soften slightly.
The peppers should still hold their shape easily but feel a little pliable when you lift them. Drain them upside down on a clean kitchen towel so no water pools inside while you move on to the filling.
Step 2: Brown the Beef

Heat the 1 tbsp olive oil in a large skillet over medium-high heat. Add the diced onion and cook, stirring, for about 4 minutes until it looks translucent. Crumble in the 1 lb ground beef and cook, breaking it up with a spoon, for 6 to 8 minutes until no pink remains.
You want the meat to get some browned, crusty bits, not just grey, because those toasted spots bring a deeper savory flavor to every bite. Stir in the minced garlic during the last minute so it softens without burning.
Step 3: Mix the Filling

Reduce the heat under the skillet to low. Stir in the 1 cup cooked rice, 1 cup tomato sauce, 1 tsp Italian seasoning, ½ tsp salt, and black pepper. Let everything cook together for 2 minutes, stirring often, until the sauce is warm and the filling looks evenly coated.
The rice should absorb some of the tomato juices but the mixture should still feel moist, not dry. Taste the filling now and add a pinch more salt if it seems at all bland, because the peppers will soak up some salt as they bake.
Step 4: Stuff the Peppers

Set the drained peppers upright in a baking dish that holds them snugly. Spoon the beef mixture into each pepper, pressing it down gently so it fills every corner. Use all the filling, mounding it a little above the rim if you need to.
They will look generously stuffed, and the filling should peek out just above the pepper edge. If there is any leftover tomato sauce, spoon a tablespoon over the top of each pepper for extra moisture during baking.
Step 5: Bake and Melt the Cheese

Cover the dish loosely with foil and bake in the preheated oven for 25 minutes. Remove the foil, sprinkle the ½ cup shredded mozzarella over the top of each pepper, then switch the oven to broil. Broil for 2 to 3 minutes, watching closely, until the cheese is bubbly and the edges turn golden brown.
The mozzarella should melt into a creamy cap with a few dark spots from the broiler, and a fork should slide through the pepper wall with no resistance. Pull the dish out as soon as the cheese looks irresistible so it doesn’t burn.
Step 6: Plate and Spoon Over the Sauce

Using a spatula, gently lift each pepper onto a plate or shallow bowl and set the pepper top alongside. Spoon any pan juices or extra warm tomato sauce around the base and scatter fresh chopped basil over everything.
The basil adds a bright pop that cuts through the richness, and the sauce pooled on the plate is perfect for dragging each bite through. Serve hot, with forks and a spoon for that extra sauce.
A Few Things That Help
- Pick peppers that stand up: At the store, set each one down and choose the four with the flattest bottoms. They will sit tall in the dish instead of tipping and spilling.
- Don’t overstuff on the first pass: Press the filling in gently and then add a little more on top if there’s room. Packing it too tight can crack the softened pepper.
- Use freshly cooked rice: Day-old rice can be dry and clumpy, and it won’t absorb the tomato sauce as well in the oven. Just-cooked rice stirred into the filling stays softer.
- Keep the broiler close at hand: The cheese can go from golden to burnt in seconds once the broiler is on. Stand right there and pull the dish as soon as those brown spots appear.
Blanch the peppers just enough to soften them without losing their shape. The bake time stays the same regardless of size.
| Pepper Size | Blanch Time |
|---|---|
| Small | 2 mins |
| Medium | 3 mins |
| Large | 4 mins |
Storing Leftover Peppers
- Refrigerate: Cooled peppers keep well in an airtight container for up to 4 days. The flavor actually deepens overnight.
- Reheating: A quick zap in the microwave works, but for the best texture, cover with foil and warm them in a 350°F oven for 12 to 15 minutes until heated through.
What to Serve With Gluten Free Stuffed Peppers
A simple green salad with a sharp vinaigrette cuts through the richness of the beef and cheese nicely. If you want something to mop up the extra tomato sauce, a few slices of toasted gluten free bread brushed with garlic oil are just the thing.
Frequently Asked Questions
Can I use uncooked rice in the filling?
No, the rice needs to be fully cooked before you mix it in because it won’t cook through inside the pepper during the bake time.
Can I freeze stuffed peppers?
Yes, assemble the peppers without baking them, wrap tightly, and freeze. Bake straight from frozen, covered with foil, at 375°F for about 40 minutes, then add cheese and broil as usual.
Do I have to use green bell peppers?
No, any color works. Red, yellow, or orange peppers are a little sweeter and their walls tend to be slightly thinner, so you may shave a minute off the blanching.
Is this recipe low carb?
Not as written with rice, but you can swap in riced cauliflower and reduce the tomato sauce to ¾ cup to keep it much lower in carbs.
