Ingredients: 6 medium bell peppers, any color, tops cut off and seeded (or halved lengthwise); 1 to 1½ lb ground beef (chuck), or 8 oz ground beef + 8 oz Italian sausage; 1 small yellow onion, diced; 2 to 8 cloves garlic, minced; 2 cups (410 g) cooked white rice (cooked method), OR ½ cup long grain white rice uncooked + 1¼ cups water + one 14.5 oz can petite diced tomatoes with their juice (raw rice method); ¼ tsp to 2½ tsp salt (see Ingredient notes); ¼ tsp black pepper; ½ tsp Italian seasoning, or 2 tsp dried oregano + ¼ tsp crushed red pepper; 1 tbsp Worcestershire sauce (optional); 1 cup (90 g) Pecorino Romano, grated (optional, in the filling); ¼ cup fresh parsley and ¼ cup fresh basil, minced (optional); 2½ to 4 cups marinara sauce, divided; ½ to 1 cup shredded mozzarella

My mother-in-law set a pan of stuffed peppers on the table the first fall I spent with her family, and I remember thinking they looked impossibly tidy for something that feeds six people. I’ve been making stuffed peppers on Sunday nights ever since, and they’ve become the meal my kids ask for by name when the weather turns.

The thing that trips most people up is the sauce underneath. It keeps the pepper bottoms from scorching and turns into the glossy, tomatoey pool you spoon over everything at the table.

Skip it and you’ll know.

I used to put the cheese on before the foil went on. Thirty-five minutes under foil and it came out oily and sad.

Cheese goes on for the last stretch only.

How do you make stuffed peppers so the rice cooks through and the pepper gets tender?

Bake covered with foil first, which traps steam and softens the pepper walls. If you use raw rice, add the full 1¼ cups of water to the filling or the rice won’t hydrate. The doneness cue is the pepper itself: a fork should slide into the side wall with no resistance.

The Method, in Plain English

Pouring some of the marinara under the peppers before baking creates a steaming layer that stops the bottoms from scorching and keeps the filling moist all the way through.
Baking covered at 350°F for 35 minutes (Spend With Pennies) traps steam inside the dish, which is what softens the pepper walls. The foil comes off only at the end so the cheese can brown without weeping oil.
Adding 1¼ cups of water directly to the filling when using raw rice gives the grains enough liquid to fully hydrate inside a sealed dish, since the pepper and sauce alone won’t supply it.

The first time I skipped the water with raw rice, I pulled the peppers out looking perfect and bit into crunchy filling. You can’t fix undercooked rice inside a finished pepper, so I don’t skip it anymore.

Reasons to Make These Stuffed Peppers

One baking dish, minimal cleanup, and the whole thing goes into the oven while you help with homework.
Works with what’s already in your pantry: a jar of marinara, a bag of rice, a pound of ground beef.
Freezer friendly assembled and uncooked, so you can make a double batch and save half for a busy week.
The filling is flexible enough to swap proteins or add cheese without changing the method at all.

Ingredients for Stuffed Peppers

6 medium bell peppers, any color, tops cut off and seeded (or halved lengthwise)
1 to 1½ lb ground beef (chuck), or 8 oz ground beef + 8 oz Italian sausage
1 small yellow onion, diced
2 to 8 cloves garlic, minced
2 cups (410 g) cooked white rice (cooked method), OR ½ cup long grain white rice uncooked + 1¼ cups water + one 14.5 oz can petite diced tomatoes with their juice (raw rice method)
¼ tsp to 2½ tsp salt (see Ingredient notes)
¼ tsp black pepper
½ tsp Italian seasoning, or 2 tsp dried oregano + ¼ tsp crushed red pepper
1 tbsp Worcestershire sauce (optional)
1 cup (90 g) Pecorino Romano, grated (optional, in the filling)
¼ cup fresh parsley and ¼ cup fresh basil, minced (optional)
2½ to 4 cups marinara sauce, divided
½ to 1 cup shredded mozzarella

A Few Notes on the Ingredients

Bell peppers vary a lot in size, and that matters here. Larger peppers hold more filling and stand up straighter in the dish.

Any color works, though red and yellow are sweeter and make the finished dish look a little brighter. If you halve them lengthwise instead of cutting the tops off, they cook faster and you get more sauce contact on the cut face.

Salt is the trickiest call in this recipe. The range runs from ¼ tsp all the way to 2½ tsp, and the difference comes down to what else is in your filling.

If you’re using Italian sausage, it brings its own salt and fat, so you need very little added. If you’re adding Pecorino Romano, that’s another salt source.

Taste the filling before it goes into the peppers and adjust from there.

For the marinara, use a sauce you’d eat straight from the jar. It’s doing double duty as the braising liquid under the peppers and the finishing sauce on top, so a thin or bland one will show.

How I Make It

Heat the oven and prep the dish. Preheat your oven to 350°F. Pour enough marinara into the bottom of a baking dish to coat it in a thin, even layer, enough that the peppers will sit in sauce rather than on bare ceramic. Set aside.
Cook the meat and aromatics. In a large skillet over medium-high heat, brown the ground beef (and sausage if using), breaking it up as it cooks, until no pink remains and the fat has rendered out, about 8 to 10 minutes. Add the diced onion and cook, stirring, until it turns translucent and soft at the edges, about 3 to 4 more minutes. Add the garlic and cook until fragrant, about 1 minute.
Build the filling. Remove the skillet from the heat. Stir in the cooked rice (or the raw rice, water, and diced tomatoes if using the raw method), Worcestershire sauce if using, Italian seasoning, salt, pepper, Pecorino Romano if using, and fresh herbs if using. The mixture should look thick and well combined, not soupy.
Fill the peppers. Pack the filling firmly into each pepper, pressing it down so there are no air pockets. Set the filled peppers upright and touching in the prepared baking dish, or lay halved peppers cut side up. Spoon the remaining marinara over the top of each one, enough to cover the filling.
Bake covered. Cover the dish tightly with aluminum foil and bake at 350°F for 35 minutes. At this point the peppers should be starting to soften but won’t be done yet. Don’t pull the foil early: that steam is what tenderizes the walls.
Add the cheese and finish uncovered. Remove the foil, scatter the shredded mozzarella over the top of each pepper, and return the dish to the oven uncovered. Bake for 10 to 12 more minutes, until the cheese is melted and golden in spots and a fork slides into the side wall of a pepper with no resistance.
Rest and serve. Pull the dish from the oven and let it sit for 5 minutes before serving. Spoon the sauce from the bottom of the dish over each pepper at the table. The USDA recommends cooking ground beef to an internal temperature of 160°F, and by the time the pepper is fork-tender, the filling is well past that mark.

Tips

If you’re using Italian sausage in place of half the beef, start with ¼ tsp of salt in the filling and taste before adding more. Sausage carries its own salt and seasoning, and it’s easy to over-salt without realizing it.
Pecorino Romano inside the filling acts as a salt source as much as a cheese. If you add it, hold back on the salt until you’ve tasted the filling, then adjust.
You can assemble the stuffed peppers completely uncooked, cover the dish tightly, and freeze them. Thaw overnight in the refrigerator and add roughly 15 minutes to the covered bake time to account for the cold start.
Halving the peppers lengthwise instead of stuffing them upright shortens the bake and gives you more surface area for the sauce to cling to. It’s a real structural difference, and I reach for that method on weeknights when I’m in a hurry.
Don’t skip the water if you go the raw rice route. Half a cup of dry rice needs that full 1¼ cups of liquid to hydrate properly, and the pepper and sauce alone won’t supply enough.

Storage and Make-Ahead

Leftover stuffed peppers keep well in an airtight container in the refrigerator for up to 4 days. The rice will keep absorbing the sauce as they sit, so add a splash of extra marinara or water to the container before you seal it.

To reheat, cover loosely and warm in a 350°F oven until heated through, or microwave covered on medium power. Either way, a little added liquid keeps them from drying out.

These freeze well assembled and uncooked. Once baked, they can also be frozen, though the pepper texture softens further on reheating.

For best results, freeze them before baking.

Rounding Out the Meal

A simple green salad with vinaigrette cuts through the richness of the meat and cheese and takes about five minutes to put together.
Crusty bread or dinner rolls are worth having on the table to soak up the marinara pooled at the bottom of the dish.
Steamed or roasted broccoli works well alongside because it doesn’t compete with the filling and gives the plate some color.
Garlic bread doubles down on the Italian flavors already in the filling and is the thing my kids always ask for first.

Tools You’ll Need

A baking dish large enough to hold 6 peppers upright and touching, about 9×13 inches. The peppers need to lean on each other a little or they’ll tip.
A large skillet for browning the meat and building the filling. Wide and heavy-bottomed is better than a small saucepan here because you need room to stir.
Aluminum foil for the covered bake. A tight seal is what creates the steam that softens the peppers, so press it down firmly around the edges of the dish.
A sharp chef’s knife for cutting the pepper tops cleanly and dicing the onion without tearing it.

Frequently Asked Questions

Can I make stuffed peppers ahead of time? Yes. Assemble them completely, cover the dish, and refrigerate overnight. Bake them straight from the fridge and add a few extra minutes to the covered bake time since they’re starting cold.

Do I need to pre-cook the peppers before stuffing them? Neither of the recipes I worked from calls for blanching or pre-cooking the peppers first. The covered bake at 350°F does the work. If your peppers are on the larger side and still feel firm after the covered stretch, give them another 5 minutes with the foil back on before adding the cheese.

Can I use brown rice instead of white? Brown rice takes significantly longer to cook than white and won’t fully hydrate inside the pepper during a standard bake. Stick with white rice, either cooked ahead or long grain white uncooked with the added water.

Why are my stuffed peppers watery? The most common reason is too much liquid in the filling or a very thin marinara. Make sure your cooked rice isn’t wet when you add it, and use a marinara with some body to it. The sauce under the peppers is supposed to be there; the filling itself should be thick.
