Southwestern Quinoa Stuffed Bell Peppers make an easy dinner that’s full of flavor and simple to prepare. Bell peppers are filled with seasoned quinoa, black beans, corn, tomatoes, and cheese before baking until tender. It’s a colorful meal that’s hearty enough for dinner but light enough to enjoy any time of year.

This recipe is naturally gluten-free and easy to customize with your favorite vegetables or protein. It’s also perfect for meal prep since the peppers reheat well throughout the week.
Whether you’re looking for a meatless Monday dinner or simply want another healthy recipe to add to your rotation, these stuffed peppers are a dependable choice.

This meatless recipe is so hearty and filling you won’t miss the meat. However, you can easily add 1 pound of ground beef or ground turkey, if desired. Additionally, you can serve it as a side dish with my Six Minute Flat Iron Steak.

How to Make Southwestern Quinoa Stuffed Bell Peppers
- Prepare the quinoa.
- Cook the vegetables and seasonings.
- Stir together the filling.
- Fill each bell pepper.
- Bake until the peppers are tender.
- Add cheese and bake until melted.
- Garnish with cilantro, avocado, or green onions.
The bell peppers make a beautiful presentation, but if you’re not fond of bell peppers, you can use poblano peppers. As well, the quinoa and black bean mixture tastes amazing without the pepper flavor. You may want to skip the peppers altogether and simply bake the quinoa in a casserole dish for the designated time.
For added flavor, top your Southwestern Quinoa Stuffed Bell Peppers with sliced avocados, sour cream, and/or salsa.
Tips for Success
- Choose peppers that can stand upright.
- Cook the quinoa before mixing the filling.
- Don’t overbake or the peppers may become too soft.
- Freshly shredded cheese melts more smoothly.
- Cover with foil during the first part of baking to keep the filling moist.
