This vegetarian stuffed peppers recipe is the hearty and filling dinner recipe you’ve been looking for! Packed with protein from quinoa, black beans, and cheese, these are sure to be one of your new favorite meatless dinner recipes.
I started making vegetarian stuffed pepper recipes over 15 years ago, during the decade I spent as a vegetarian. As someone who’s been cooking for myself (and now my family) for over 20 years, and has developed over 70 main dish recipes for this website (with 20 of them being vegetarian meals), I’ve learned what makes a truly satisfying meatless dinner. Through extensive testing, I’ve perfected the quinoa-to-bean ratio that keeps these peppers filling without being too heavy as well as finalizing the ideal baking time and temperature to get tender peppers with perfectly melted cheese.
What I love most about this recipe is that it’s become a favorite in our house for everyone (even the meat eaters devour these)! They hold up incredibly well for meal prep throughout the week, and they’re a fun yet easy way to mix up your dinner routine. So for your next meatless Monday, give these yummy quinoa stuffed peppers a try!

Why You’ll Love this Vegetarian Stuffed Peppers Recipe
A great make ahead meal. For those who love to meal prep, this is a great recipe to make as these veggie stuffed peppers hold up well in the fridge for the week.
Packed with plant-based proteins! Quinoa is rich in protein, boasting eight grams of protein in one cup. Unlike some plant-based proteins, quinoa is a complete protein on it’s own! Black beans are another plant-based protein powerhouse with 15 grams of protein in one cup.
A great way to eat a lot of vegetables! Bell pepper halves are the perfect vessel for your dinner, and we’re packing in more veggies with added spinach too!
Ingredients For Vegetarian Stuffed Peppers
- Bell Peppers. You can use red peppers, yellow peppers, green peppers, orange peppers, or a combination of colors for your bell pepper halves in this recipe. Select whatever looks best at your store or farmers market.
- Dry Quinoa. I generally use white quinoa or tri-colored (rainbow) quinoa when making stuffed peppers.
- Water. Water is used to cook our quinoa.
- Cheese. We use cheese in the filling as a binder and as a topping too. This recipe is great with a spicy cheese like pepper jack or a Mexican cheese blend, with any kind of cheddar cheese, or a Monterey jack cheese. I’ll use whatever cheese I happen to have in my fridge (I do live in Wisconsin after all…), or whatever happens to be on sale at my grocery store that week. Shredded mozzarella can work in a pinch if needed too.
- Fresh Spinach. Extra veggies are always a good idea in my book! We add strips of fresh spinach into our recipe for the perfect filling.
- Taco Seasoning. The taco seasoning is where we’re getting a lot of the great flavor in this recipe. We’re simply using a premade packet of taco seasoning to keep tings easy and avoid measuring out all the spices individually. Most taco seasoning mixes contain chili powder, garlic powder, onion powder, salt, pepper, and cumin. They may also have paprika, oregano, and cayanne pepper.
- Black Beans. The black beans are our main source of protein in this vegetarian meal.
- Olive Oil. We’re using just a little bit of olive oil to rub onto and roast our bell peppers.
See recipe card below for a full list of ingredients and measurements.
How to Make Vegetarian Stuffed Peppers
Cook the quinoa with the water per package directions.
While the quinoa cooks, preheat the oven to 400°F, line a baking sheet with parchment paper.
Rub the outside of the peppers with a thin layer of olive oil and place onto the baking sheet.
In a large bowl, mix together the cooked quinoa, black beans, taco seasoning, spinach, and 4-5 ounces of the shredded cheese.
Divide the filling between the peppers, gently pushing the filling in.
Bake the filled peppers for 20 minutes.
Remove the peppers from the oven and turn on the broiler.
Top the peppers with an additional 1-2 ounces of cheese, then broil the cheese-topped peppers for a few minutes (keeping a close eye on them) until the cheese is nice and melty.
Have a Little Extra Filling?
Depending on the size of your peppers, you may end up with a little extra quinoa mixture. Enjoy this on it’s on, as a salad topping, or as a taco filling!
Quinoa Stuffed Peppers Recipe Variations and Substitutions
- Use a different grain. I’ve made this recipe with brown rice and white rice too if you do not have quinoa on hand. Both work great!
- Replace the water for cooking the quinoa with broth or stock. Amp up the flavors in this dish even more by using vegetable broth or vegetable stock as your cooking liquid for the quinoa!
- Add diced tomatoes to your filling. Want even more veggies? Drain a can of your favorite diced tomatoes and toss it in your quinoa filling too.
- Add onion if preferred. We’re keeping things easy in our base recipe, but if you’d like to take a little extra time to prep an onion for your filling, go for it! Sauté onion in olive oil until translucent and starting to brown, then add it to your filling.
- Mix cooked corn into your filling. You can use canned corn, or fresh sweet corn that’s been cooked and cut from the cob.
Possible Dietary Restrictions?
This recipe is vegetarian and gluten-free as written.
One small modification is needed to turn this into a dairy-free and vegan stuffed peppers recipe: replace the standard cheese one-for-one with your favorite vegan cheese.
Tips For Making Stuffed Peppers With Quinoa
Rinse your quinoa. Quinoa has a protective coating (called saponin) on it that can result in a batch of quinoa that tastes “off”, overly earthy, and bitter. Use a fine mesh strainer to rinse your quinoa before cooking to avoid this.
Try to cut pepper halves so they’ll sit flat(ish) when on the baking tray. If you can get your bell pepper half to sit mostly flat on your pan, they’re a little easier to stuff. When they sit at an angle on your tray, it can be harder to keep your filling in.
How to Serve Vegetarian Stuffed Peppers With Quinoa
My favorite way to enjoy these veggie stuffed peppers is alongside a big green salad! A simple salad of greens tossed in a vinaigrette, or even your favorite bagged salad, goes along way to fill out your meal.
You can also serve these peppers with some additional toppings if you’d like. A dollop of sour cream, some fresh cilantro, a squeeze of fresh lime juice, a dash of hot sauce, a scoop of your favorite salsa… treat them like you’d treat a taco.
Have some family members who need meat? Make a batch of our ground beef stuffed peppers to serve alongside this vegetarian version.
Storage and Reheating
Store fully cooled leftovers in an airtight container in the refrigerator for 4-5 days.
To reheat, place individual portions onto a microwave safe plate (I like to cut mine into pieces prior to heat) and microwave until heated through. Alternatively, place stuffed peppers onto a baking dish and heat in the oven at 350°F until your desired temperature has been reached.
Recipe FAQs
You do not need to precook your bell peppers prior to stuffing (especially since we’re cutting our peppers in half and not stuffing a full pepper). However, if you prefer your peppers to be cooked to a softer texture then you can precook them. To do so simply blanch the peppers in gently boiling water for a few minutes on the stove. Be sure to pat them dry before stuffing if you add this step to remove excess moisture.
There are a few reasons your stuffed peppers may become soggy. If you decided to precook your bell peppers, they may have been cooked too much prior to stuffing and baking. Filling ingredients (usually veggies) may have released excess water resulting in soggy peppers. Or you may have simply left the peppers in too long and overbaked them.
