Easy Vegan Stuffed Bell Peppers with Quinoa and Black Beans

A good stuffed pepper should feel hearty, colorful, and easy enough for a weeknight. This one checks all three boxes without needing meat, dairy, or anything fussy.

These vegan stuffed bell peppers are packed with quinoa or rice, black beans, tomatoes, corn, warm spices, and a melty layer of shredded vegan cheese on top. They’re cozy but still fresh. Filling but not heavy. And because the peppers do most of the presentation work for you, they look like you tried harder than you did.

You’ll spend about 20 minutes prepping, then the oven takes over. That makes this recipe perfect for meal prep, a simple family dinner, or that moment when you’ve got a few bell peppers in the fridge and no real plan yet.

Colorful peppers make this dinner feel bright before you even take a bite.

These vegan stuffed peppers are easy to love

The best thing about this recipe is how balanced it feels. You’ve got tender roasted bell peppers on the outside, a savory filling inside, and just enough vegan cheese on top to make each bite feel comforting.

The filling is built from simple pantry ingredients:

• Cooked quinoa or rice

• Black beans

• Diced tomatoes

• Corn

• Onion and garlic

• Chili powder, cumin, and paprika

  
  

That mix gives you a little sweetness from the corn, a little earthiness from the beans, and a gentle smoky warmth from the spices. Nothing is too hot or too intense, so it works well for different tastes. If you like more heat, you can easily add cayenne, diced jalapeño, or a splash of hot sauce.

These Stuffed Peppers also make a great bridge meal if you’re cooking for people who aren’t fully vegan. They’re familiar, filling, and not trying too hard. No one has to be convinced by a complicated ingredient list.

A quick note on the grain: quinoa gives the filling a slightly nutty taste and adds a nice texture. Rice makes the dish softer and more classic. Brown rice, white rice, or even leftover takeout rice can work. Use what you have.

If you came here looking for plant based stuffed peppers, this is the kind of recipe that fits the craving: whole-food ingredients, lots of color, and a dinner that actually satisfies.

Here’s everything you’ll need

This recipe makes 4 servings, with one large stuffed pepper per serving. If your peppers are smaller, you may have a little extra filling. That’s not a bad thing. Spoon it into a small oven safe dish and bake it alongside the peppers, or save it for a quick lunch bowl.

Ingredient	Amount
Large bell peppers, any color	4
Olive oil	1 tablespoon
Onion, diced	1
Garlic, minced	2 cloves
Cooked quinoa or rice	1 cup
Black beans, drained and rinsed	1 can, 15 ounces
Diced tomatoes, drained	1 can, 14.5 ounces
Corn kernels, fresh or frozen	1 cup
Chili powder	1 teaspoon
Cumin	1/2 teaspoon
Paprika	1/2 teaspoon
Salt and pepper	To taste
Shredded vegan cheese	1 cup
Cilantro or parsley	Optional, for topping

For the bell peppers, any color will work. Red, yellow, and orange peppers tend to taste sweeter. Green peppers have a slightly sharper flavor. A mix of colors looks really pretty in the baking dish, but there’s no need to overthink it.

For vegan cheese, use a shredded style that melts well. Cheddar-style, Mexican-style, or mozzarella-style shreds all work.

Simple pantry staples turn into a full, colorful meal.

Nutrition will vary based on your vegan cheese, the size of your peppers, and whether you use quinoa or rice. Think of these numbers as a helpful estimate, not a strict label.

Make the filling rich and flavorful before baking

Start by heating your oven to 375°F. Grease a baking dish large enough to hold the peppers upright. A medium casserole dish usually works well.

Next, prepare the peppers. Slice off the tops, then scoop out the seeds and membranes. Try to keep the pepper walls intact so they hold the filling. If a pepper wobbles, you can slice a very thin layer off the bottom to help it stand. Just don’t cut all the way through, or the filling can leak out.

Now grab a large skillet.

Warm 1 tablespoon olive oil over medium heat. Add the diced onion and minced garlic. Cook them until the onion softens and turns translucent. This step only takes a few minutes, but it makes a big difference. Raw onion can taste sharp inside stuffed peppers. Soften it first, and the whole filling tastes better.

Add the cooked quinoa or rice, black beans, drained diced tomatoes, corn, chili powder, cumin, paprika, salt, and pepper. Stir everything well so the spices coat the beans and grain evenly.

Let the mixture cook for about 5 minutes. You’re not trying to cook it from scratch here, since the quinoa or rice is already cooked. You’re just warming it through and letting the flavors come together.

Taste the filling before it goes into the peppers. This is the easiest place to adjust it. Add more salt if it tastes flat. Add more chili powder for warmth. Add smoked paprika if you want a little more depth.

The filling should taste good on its own. If it tastes bland in the skillet, it won’t magically become bold in the oven.

Let the filling taste delicious before it ever reaches the peppers.

Bake the peppers until tender and melty

Spoon the filling into the hollowed bell peppers. Pack it in firmly, but don’t smash it down so hard that the peppers split. Place the filled peppers upright in your greased baking dish.

Sprinkle shredded vegan cheese over the top of each pepper. Try to cover the filling, but let a little color peek through. It looks good and helps you see what’s inside.

Cover the baking dish with foil. Bake for 27 to 30 minutes at 375°F. The foil traps steam, which helps the peppers soften without drying out.

Then remove the foil and bake for another 10 minutes. This gives the vegan cheese time to melt more fully and lets the tops finish nicely.

When the peppers are done, take them out of the oven and let them cool for a few minutes. This short rest helps the filling settle, and it also saves you from burning your mouth on a tomato-bean lava situation. Top with cilantro or parsley if you like.

The peppers should be tender enough to cut with a fork, but not collapsing. If you like very soft peppers, add another 5 to 10 minutes to the covered bake time.

A generous sprinkle of vegan cheese gives the peppers a cozy finish.

Store, reheat, and meal prep them without drying them out

These vegan stuffed bell peppers are meal-prep friendly, which makes them even better. Once baked, let them cool, then store them in an airtight container in the fridge.

They’ll keep well for about 3 to 4 days.

To reheat, place a pepper in a baking dish, cover loosely with foil, and warm at 350°F until heated through. You can also microwave one pepper at a time. If using the microwave, cover it with a microwave-safe lid or plate to help keep moisture in.

If the filling seems a little dry after chilling, add a splash of vegetable broth before reheating. That brings it right back.

You can also prep parts of the recipe ahead:

Make-ahead step	How to do it
Cook the grain	Make quinoa or rice up to 3 days ahead and refrigerate it.
Mix the filling	Prepare the full filling a day ahead and store it in the fridge.
Prep the peppers	Cut and clean the peppers a day ahead, then refrigerate them covered.
Assemble before baking	Stuff the peppers, cover the dish, and refrigerate for up to 24 hours.

If baking straight from the fridge, add a few extra minutes to the covered baking time. Cold filling needs a little longer to heat through.

Freezing can work, but the pepper texture will soften after thawing. If you don’t mind softer peppers, freeze them after baking. Wrap each one well, then store in a freezer-safe container. Thaw overnight in the fridge before reheating.
