If you think meatless dinners can't be hearty, these Vegetarian Quinoa Stuffed Peppers are about to prove you wrong. Tender bell peppers get loaded up with a savory, nutrient-dense mixture of quinoa, black beans, and corn, then topped with melty cheese and baked until everything is bubbling and gorgeous. It's a genuinely satisfying easy weeknight meal that even confirmed meat eaters will ask for seconds on.
This version swaps in quinoa where our classic Ground Beef Stuffed Peppers uses rice and meat, and it comes together with ingredients you probably already have in your pantry.
The quinoa and beans bring plenty of protein and fiber, the corn adds a little sweetness, and the cheese on top ties it all together into something you'll want to make on repeat. Bonus: it's naturally gluten-free, so it works for a crowd with mixed dietary needs.

Ingredients and Substitutions
To make these delicious Vegetarian Quinoa Stuffed Peppers, you will need the following ingredients (full measurements in recipe card below):
- bell peppers - use large, wide peppers that can hold a generous amount of filling. Red, yellow, orange, or green all work.
- olive oil - for sautéing the aromatics. Avocado or vegetable oil work as substitutes.
- onion and garlic - always use fresh for the best flavor here.
- tomato paste - adds a hint of sweetness and acidity that ties the filling together. Tomato puree or crushed tomatoes work in a pinch.
- ground cumin and paprika - bring warm, smoky flavor to the filling. Don't skip these, they do a lot of the flavor work.
- quinoa - use any variety, though white quinoa gives the fluffiest texture. It cooks right in with the broth and other ingredients.
- black beans - canned is easiest, but feel free to cook your own from scratch.
- corn - frozen or canned both work well here.
- vegetable broth - cooks the quinoa and infuses it with flavor. Water works too if that's what you have.
- fresh parsley - adds a pop of freshness and color, both in the filling and as a garnish. Fresh cilantro works well as a swap if you prefer its flavor.
- cheese - shredded Monterey Jack or cheddar melts beautifully on top, but use whatever melty cheese you love.
Equipment
You will need measuring cups and spoons, a large skillet, and a 9x13-inch casserole pan or large baking sheet.
Instructions
- Prepare the peppers. Cut the bell peppers into halves and remove and discard the seeds. Place the peppers, cut sides up, in a 9x13-inch casserole pan or large baking sheet and set aside.
- Sauté the aromatics. Heat oil in a large skillet over medium-high heat until it sizzles, about 1 minute. Add the onion and garlic and sauté until tender, about 3 to 4 minutes.
- Add the seasoning. Add the tomato paste, cumin, paprika, salt, and pepper. Stir well until smooth.
- Simmer the filling. Add the quinoa, black beans, corn, and vegetable broth. Mix well and bring to a simmer. Cover and let simmer for 15 minutes until the quinoa is tender and the liquid is absorbed. Stir in the parsley.
- Stuff the peppers. Fill each pepper half with the quinoa filling and sprinkle a tablespoon of cheese on top of each one.
- Bake. Bake uncovered in a 400°F preheated oven for 40 to 45 minutes until the cheese is bubbling and the peppers are tender.
- Rest and serve. Let the stuffed peppers rest for 5 minutes. Garnish with parsley, slice, and serve warm.
Expert Tip: Don't Overstuff the Peppers
It's tempting to pile the filling as high as it will go, but give the peppers a little breathing room. Overstuffed peppers tend to spill filling in the oven as the peppers shrink slightly while baking, so fill them generously but leave a bit of space at the top.
More Tips and Tricks
- Precook the quinoa ahead of time. Cook it up to 3 days in advance and store it in the fridge, then just stir it into the bean and corn mixture without any extra broth or water.
- Cook until fork-tender. The peppers should be tender but still hold their shape. Overcooking makes them mushy and hard to handle.
- Use a casserole dish with sides. It keeps the peppers upright and holds any filling that might spill over during baking.
- Taste as you go. Give the filling a taste before stuffing the peppers and adjust the salt, cumin, or paprika to your liking.
- Double the filling. Make extra filling to use in burrito bowls or as a quick side dish on its own throughout the week.
Recipe Variations
- Use other grains. Swap the quinoa for cooked white or brown rice for a classic rice mixture, or try cauliflower rice or farro.
- Change up the beans. Try chickpeas, pinto beans, or cooked lentils for added protein.
- Add more veggies. Stir in diced zucchini, mushrooms, or spinach along with the onion and garlic for extra fresh veggies in every bite.
- Add some heat. Stir in chili powder, red pepper flakes, or diced jalapeños, or top with salsa or hot sauce before serving.
- Go vegan. Skip the cheese or use your favorite vegan cheese, and stir in a tablespoon of nutritional yeast for a cheesy flavor without the dairy.

FAQ
Quinoa, rice, black beans, corn, and cheese are classic choices, but stuffed peppers are endlessly flexible. Feel free to add other fresh veggies like diced zucchini or mushrooms, swap in different beans, or top with your favorite salsa or hot sauce to make it your own.
No, the peppers cook through in the oven along with the filling, so there's no need to blanch or pre-bake them first.
Yes, just skip the cheese or use a vegan cheese substitute. Adding a tablespoon of nutritional yeast to the filling gives it a cheesy flavor without any dairy.
This can happen if the peppers release extra moisture as they cook. Letting the peppers rest for 5 minutes after baking helps some of that liquid settle before serving.
