Stuffed roasted red peppers are the kind of easy dinner recipe that makes a simple weeknight feel a little special.
Sweet red peppers become tender and caramelized in the oven, while a savory rice-and-vegetable filling gets tucked inside and covered with bubbly golden cheese.
The result is colorful, comforting, satisfying and surprisingly simple.
I built this version around what makes stuffed bell peppers so appealing: a hearty filling, plenty of roasted vegetable flavor and that irresistible melted-cheese finish.
It also takes a few smart ideas that repeatedly show up in popular stuffed pepper recipes—cooked rice for reliable texture, vegetables for extra flavor, herbs for freshness and a little moisture in the baking dish—then brings them together into one streamlined dinner.
And there is a very good reason to use red peppers here.
They become naturally sweet as they roast, creating a delicious contrast with savory garlic, tomatoes, herbs, rice and cheese.
Why These Stuffed Roasted Red Peppers Work
The secret is layering flavor rather than throwing everything into a pepper and hoping for the best.
First, the red peppers get a head start in the oven.
That softens their thick walls and begins developing their natural sweetness.
Meanwhile, onion and garlic are gently cooked with herbs before the rice, tomatoes and greens are folded through.
That small extra step makes a huge difference.
You get a filling that tastes seasoned throughout instead of cheese simply covering an under-seasoned center.
The rice adds satisfying substance.
The vegetables add texture.
The sun-dried tomatoes bring concentrated savory-sweet flavor.
Mozzarella melts into the filling and creates that gorgeous golden topping everyone reaches for first.
This is why these vegetarian stuffed peppers feel like a proper dinner rather than a vegetable side dish.
The technique also gives you flexibility.
You can use leftover cooked rice, swap in quinoa, add chickpeas or white beans, or turn the recipe into a more Mediterranean-style meal with feta and extra herbs.

Ingredients
- 4 large red bell peppers
- 2 cups cooked long-grain or brown rice
- 1 tablespoon extra-virgin olive oil
- 1 small yellow onion, finely diced
- 3 garlic cloves, minced
- ½ cup chopped sun-dried tomatoes
- 1 cup baby spinach, roughly chopped
- ¼ cup fresh parsley, chopped
- 2 tablespoons fresh basil, chopped
- 1 teaspoon dried oregano
- ½ teaspoon smoked paprika
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
- ¼ teaspoon red pepper flakes, optional
- 1 cup shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- ⅓ cup vegetable broth or water
How To Make Them
Start by heating your oven to 375°F.
Slice the peppers in half lengthwise and remove the seeds and white membranes.
Place them cut-side up in a lightly oiled baking dish.
Pour the vegetable broth or water around the peppers.
This creates gentle steam underneath while they roast, helping them become tender without drying out.
Cover loosely with foil and bake for 10–12 minutes.
While the peppers are getting their head start, heat olive oil in a skillet over medium heat.
Add the onion and cook for about 4–5 minutes, until softened.
Add the garlic, oregano, smoked paprika and red pepper flakes.
Cook for about 30 seconds.
You want the garlic fragrant.
You do not want it browned.
Add the chopped sun-dried tomatoes and spinach.
Cook until the spinach wilts and the mixture looks fairly dry.
That last detail matters.
Too much moisture can make the filling soggy.
Stir in the cooked rice.
Season with salt and black pepper.
Remove the skillet from the heat.
Fold in the parsley, basil, ½ cup mozzarella and Parmesan.
Taste the filling.
This is your chance to adjust the seasoning before it disappears inside the peppers.
Remove the partially roasted peppers from the oven.
Spoon the filling generously into each pepper half.
Do not be shy here.
A slightly heaped filling gives you those beautiful, abundant stuffed bell peppers people expect from a cozy dinner recipe.
Sprinkle the remaining mozzarella over the top.
Return the uncovered baking dish to the oven.
Bake for 20–25 minutes, until the peppers are tender and the cheese is bubbling and golden.
For an extra-crispy cheese topping, switch to broil for 1–2 minutes at the end.
Watch carefully.
Cheese goes from gorgeous to burnt remarkably fast.
Let the peppers rest for about five minutes.
Finish with fresh parsley and a little cracked black pepper.
Then serve.
What Makes The Flavor So Good?
The red pepper is doing more work than you might think.
Roasting brings out its natural sweetness and softens the texture without making it collapse.
That sweetness balances the salty Parmesan and mozzarella.
Sun-dried tomatoes provide concentrated tomato flavor, while garlic and oregano create a savory backbone.
The spinach adds earthy freshness.
Smoked paprika gives the rice filling a subtle warmth that makes the whole dish taste deeper.
It is a simple combination.
But simple does not mean boring.
That is the beauty of a really good stuffed peppers recipe.
Every forkful gives you soft roasted pepper, seasoned rice, vegetables and melted cheese together.
Pro Tips For Better Stuffed Peppers
Use red peppers of similar size.
They will cook more evenly, which means nobody gets a perfectly tender pepper while another is still stubbornly firm.
Use cooked rice.
This keeps the recipe predictable and eliminates the risk of undercooked rice soaking up all the liquid inside your peppers.
Keep the filling fairly dry.
Cook excess moisture out of the spinach and tomatoes before adding the rice.
This gives you a hearty filling rather than a watery one.
Do not skip the pre-bake.
Starting the peppers before stuffing them gives them a head start toward that soft, roasted texture.
It is especially useful when making large easy stuffed bell peppers.
Broil at the end.
A quick blast of high heat creates those irresistible browned cheese spots without requiring you to overcook the peppers.
Easy Variations To Try
Want a more filling dinner?
Add 1 cup drained chickpeas or white beans to the rice mixture.
For a Mexican stuffed peppers twist, replace the oregano with cumin and chili powder, add black beans and corn, then finish with Monterey Jack.
For Italian stuffed peppers, add chopped basil, extra Parmesan and a little marinara around the base of the peppers.
You can also make chicken stuffed peppers by adding finely diced cooked chicken.
Prefer a lower-carb option?
Swap the rice for cauliflower rice and add extra mushrooms or spinach.
And for a creamy variation, stir a few tablespoons of softened cream cheese into the warm filling before stuffing.
There is plenty of room to make this recipe your own.
What To Serve With Stuffed Roasted Red Peppers
These peppers are filling enough to serve as the main event.
I love pairing them with a crisp green salad dressed with lemon and olive oil.
Roasted broccoli works beautifully too.
For a heartier dinner, add crusty garlic bread and a simple tomato salad.
They also make an excellent meal-prep option.
Store cooled peppers in an airtight container in the refrigerator for up to 4 days.
Reheat in a 350°F oven until hot, or microwave individual portions.
The cheese may not be quite as crisp after reheating, but the filling stays wonderfully comforting.
