In just 35 minutes, you can make colorful stuffed peppers that are full of protein.
Stuffed peppers always sound like a great idea, but then you remember that they usually take 90 minutes and make a mess in every pot in your kitchen. Not these. These Quick Vegetarian Stuffed Peppers are colorful enough to get kids to eat their vegetables and are ready in 35 minutes. They use mostly pantry staples.
The secret is? We’re not playing with raw peppers that take a long time to get soft. We partially cook them while the filling is being made, and then everything cooks all the way through in the oven. Also, the beans and quinoa make these meals really filling, not the kind of vegetarian dinner where you need a snack in an hour.

- 35 minutes total—for prep and baking

Why This Recipe Works for Real Weeknights
On a Tuesday, with only 20 minutes to go before soccer practice pickup, I made stuffed peppers for the first time. My kids were starving, I had promised them something “healthy and homemade,” and I was staring at four bell peppers wondering why traditional recipes take 90 minutes for what is basically rice in a vegetable.
That night, I found the shortcut that changed everything: par-cook the peppers in the microwave while you make the filling on the stovetop. Both parts are ready at the same time; you put them together, bake for 15 minutes just to get everything hot and bubbly with cheese, and dinner is ready. You don’t have to wait for the raw peppers to slowly soften while the filling cools down.
I tried this recipe more than 20 times with different grains, vegetables, and cooking methods. I finally settled on this combination because:
Why quinoa is better than rice: Quinoa cooks faster (15 minutes for quinoa vs. 45 minutes for brown rice), has all nine essential amino acids, and is lighter, which kids like better than rice fillings that are heavy and sticky. Plus, microwave quinoa packets that are already cooked cut down on prep time to almost nothing.
Why par-cooking is important: When you steam peppers in the microwave, the water breaks down the cell walls, making them perfectly tender without the 45 minutes in the oven that traditional recipes call for. The peppers stay bright and have the right amount of spice.
Why adding black beans is so smart: Black beans turn this from a “side dish in a pepper” into a real main course that fills you up. When you add quinoa, you get a full amino acid profile that keeps everyone happy until breakfast.
Setting honest expectations: These peppers cook the fastest when you use pre-cooked quinoa and frozen vegetables that have already been diced. If you’re making quinoa from scratch and cutting everything up yourself, add 15 to 20 minutes to the time. It all depends on your evening; both ways work.
Things You Will Need
For the Peppers
4 big bell peppers of any color
When you cook red, orange, and yellow peppers, they taste sweeter. Green peppers taste a little more bitter and earthy. Red and yellow are usually the best colors for kids. Pick peppers that stand up straight. This will make it easier to fill and bake them.
For the Filling of Quinoa and Vegetables
One 8.5 oz packet of pre-cooked quinoa or 1½ cups of cooked quinoa
You can find pre-cooked microwave quinoa packets in the rice aisle. They save you 15 minutes. If you’re cooking from scratch, use 1 cup of water and ½ cup of dry quinoa. Let it simmer for 15 minutes.
1 can (15 oz) of black beans, drained and rinsed
It gives you protein, fiber, and a hearty texture. About 40% of the sodium in canned beans is removed by rinsing them.
1 can (14.5 oz) diced tomatoes with green chiles (or just plain diced tomatoes)
The green chile version adds a little flavor without a lot of heat, making it great for families. If you want it to be less spicy, plain diced tomatoes will work.
1 cup of corn kernels, either fresh, frozen, or canned
Kids love the sweetness it adds and the beautiful color contrast.
1 small onion, chopped up (about ¾ cup)
You can use either yellow or white onion. Use ½ cup of frozen diced onion to speed up the prep.
Three minced cloves of garlic
1 teaspoon of cumin
1 teaspoon of chili powder
½ teaspoon of smoked paprika
Add salt and pepper to taste.
1 tablespoon of olive oil
To Top
1½ cups shredded Mexican cheese blend (or cheddar)
For vegans, use your favorite dairy-free cheese shreds.
Optional toppings: fresh cilantro, sour cream, avocado slices, and hot sauce
What You Need
Important:
- A big baking dish that can go in the oven (9×13 inches is perfect)
- A big frying pan or skillet
- Bowl or dish that can go in the microwave (to cook the peppers halfway)
- A cutting board and a sharp knife
- Cups and spoons for measuring
Helpful but Not Required:
- A packet of pre-cooked quinoa (saves a lot of time)
- Frozen chopped onions (saves time in the kitchen)
Instructions in Steps
Step 1: Preheat and prepare the peppers (5 minutes)
Set your oven to 400°F.
Cut each bell pepper in half lengthwise, starting at the stem. Take out the white membrane and seeds from each half. You should have eight “boats” of pepper.
Put the cut sides of the pepper halves down in a dish that can go in the microwave. Put 2 tablespoons of water in the dish. Use plastic wrap or a damp paper towel to loosely cover.
Put the peppers in the microwave on high for 4 to 5 minutes, or until they are a little soft but still hold their shape. They should be flexible but not mushy.
Why this works: Microwaving peppers for a short time makes them soft and ready to eat much faster than cooking them in the oven. The steam gets through the cell walls and makes them softer all over.
While the peppers are in the microwave, start making the filling!
Step 2: Cook the Aromatics (3 Minutes)
Put a lot of olive oil in a big skillet over medium-high heat.
Add the chopped onion and cook for 2–3 minutes, or until it is soft and clear. The onions should smell sweet, not like they are still raw.
Put in some minced garlic, cumin, chili powder, and smoked paprika. For 30 seconds, stir constantly until it smells good. The spices should bloom in the oil, and you’ll be able to smell them come to life.
Step 3: Make the Filling (5 Minutes)
Put the drained black beans, diced tomatoes (with their juice), and corn in the pan with the aromatics.
Mix everything together and let it cook for 3 to 4 minutes. The liquid from the tomatoes should thicken, and the mixture should get thicker.
Add the cooked quinoa and mix until everything is well mixed and hot.
Add a lot of salt and pepper. Taste the filling; it should be flavorful and well-seasoned on its own.
Take it off the heat and mix in half a cup of the shredded cheese. This makes the filling richer and helps it stick together.
Step 4: Put together the stuffed peppers (3 minutes)
To prepare your baking dish, lightly grease it or spray it with cooking spray.
Place the pepper halves that have been partially cooked with the cut sides up in the dish. They should fit well.
Spread the quinoa vegetable filling evenly among the eight pepper halves, making a small mound in each one. Don’t worry about being exact; it’s best to give big portions!
Divide the rest of the shredded cheese evenly and put it on top of each stuffed pepper.
Step 5: Bake for 15 Minutes, or Until Bubbly
Put the baking dish in the oven that has been preheated to 400°F.
Put the cheese in the oven for 12 to 15 minutes, or until it is melted, bubbly, and starting to turn golden brown in some places.
Visual cue for doneness: The cheese should look like a pizza ad, with the filling bubbling underneath and the edges slightly browned.
Step 6: Let it rest for 5 minutes and then serve.
Take the stuffed peppers out of the oven and let them sit for five minutes before serving. This lets the filling set a little and keeps mouths from getting burned!
Serve hot with fresh cilantro, a dollop of sour cream, avocado slices, or your favorite hot sauce on top.
Serving suggestion: These are big enough to be a meal on their own, but a simple side salad or some crusty bread goes well with them.
Pro Tips for Making the Best Stuffed Peppers
Pick the Right Peppers: Look for peppers with flat bottoms that will stand up straight (or lie flat when you cut them in half). When peppers are wobbly, they fall over and spill their filling.
Don’t Skip the Par-Cook: It takes more than 45 minutes for raw peppers to get soft in the oven. This is a weeknight recipe because of the microwave par-cook.
Season Generously: The filling should taste a little too salty before you put it in the peppers. The flavors come together as it bakes and the cheese melts.
Use Quinoa That Has Already Been Cooked: This isn’t cheating; it’s smart cooking on a weeknight. Microwave quinoa packets are just as healthy as homemade ones and take 15 minutes less time.
Tips for storing and making ahead
Put Together Ahead of Time:
Get everything ready up to Step 4 (put together but not baked). Wrap tightly in foil or plastic wrap and put in the fridge for up to two days. When you’re ready to eat, bake them at 400°F for 20 to 25 minutes. If they’re cold, add 5 to 10 minutes.
Storing in the fridge:
You can keep baked stuffed peppers in an airtight container for up to four days. You can reheat it in the oven at 350°F for 15 minutes or in the microwave for 2 to 3 minutes.
Storing in the Freezer:
You can freeze unbaked peppers that have been put together for up to three months. Put it in the fridge overnight to thaw, then bake it as directed, adding 5 minutes. OR bake from frozen at 375°F for 35 to 40 minutes.
Plan for Meal Prep:
Make the filling on Sunday and keep it separate from the peppers. On weeknights, cook the peppers halfway, fill them, and bake them fresh. The filling can be kept in the fridge for five days.
Tasty Changes
Mediterranean Style: Instead of black beans, use chickpeas; instead of Mexican blend, use diced tomatoes with basil; and instead of Mexican blend, use crumbled feta cheese. Top with fresh mint.
Tex-Mex Loaded: Put cooked ground turkey or beef in the filling, top it with jalapeño slices, and serve it with guacamole and more salsa.
Italian Inspired: Instead of diced tomatoes, use marinara sauce. Add Italian seasoning, use mozzarella cheese, and top with fresh basil.
Low-Carb Option: Instead of quinoa, use riced cauliflower and double the black beans for protein.
Mild for Kids: Leave out the chili powder and green chiles, use plain diced tomatoes, and add more cheese to make it more appealing to kids.

Questions That Are Often Asked
Can I make stuffed peppers ahead of time?
Of course! You can put the stuffed peppers together completely (with the cheese topping) and store them in the fridge for up to two days. When you’re ready to eat, bake them at 400°F for 20 to 25 minutes, adding 5 to 10 minutes because they’re starting cold. You can also freeze stuffed peppers that haven’t been baked for up to three months.
What is the best way to cook quinoa quickly?
The fastest choice is pre-cooked microwave quinoa packets, which you can find in the rice aisle. You only need to cook them for 90 seconds. If you’re making it from scratch, rinse ½ cup of dry quinoa and mix it with 1 cup of water. Bring the water to a boil, then lower the heat and cover the pot. Cook for 15 minutes, or until the water is gone.
Can I use other vegetables in the filling?
Yes! This filling can be used in a lot of different ways. You could also try adding diced zucchini, spinach, mushrooms, or shredded carrots. Add any other vegetables and sauté them with the onions. To keep the peppers from getting too full, keep the total volume about the same.
How can I make this recipe vegan?
You can leave out the cheese or use your favorite vegan cheese shreds (Violife and Daiya melt well). The only thing that needs to be changed is that the filling is already vegan. Is there another grain I can use instead of quinoa?
Yes! You can use cooked brown rice, farro, or cauliflower rice. If you’re using a grain that takes longer to cook than quinoa, change the cooking time. Another great shortcut is to buy pre-cooked microwave rice pouches.
My kids don’t like food that is spicy. What can I do to make this less strong?
Instead of tomatoes with green chiles, use plain diced tomatoes. Don’t use chili powder, and cut the cumin down to 1/2 teaspoon. The cheese, corn, beans, and peppers all add a lot of flavor without any heat.
Can I use the Instant Pot or slow cooker to cook these?
Instant Pot: Put the stuffed peppers on the trivet with 1 cup of water underneath. Cook under pressure on high for 5 minutes, then let the pressure out quickly. Add cheese and broil until it melts.
Slow Cooker: Put the stuffed peppers in the slow cooker, add ¼ cup of water to the bottom, cover, and cook on low for 3–4 hours or high for 1.5–2 hours. Put the cheese in the last 15 minutes.
How many stuffed peppers should I give each person?
Two stuffed pepper halves make a filling main dish for adults. One to one and a half halves is usually enough for kids or people who don’t eat much. The protein from quinoa and beans makes the filling very filling.
What sides go well with stuffed peppers?
A simple green salad, crusty bread, Spanish rice, or black beans and rice all go well together. The stuffed peppers are filling enough on their own for a light meal.
