Ingredients

  • 4 green bell peppers, halved and seeded
  • 1 tablespoon olive oil
  • 1 small onion, finely diced
  • 2 cloves garlic, minced
  • 1 cup (dry, about 3 cups cooked) quinoa, cooked
  • 1 can (15 oz) black beans, drained and rinsed
  • 1 cup corn kernels
  • 1 can (14.5 oz) diced tomatoes
  • 1 teaspoon ground cumin
  • 1/2 teaspoon chili powder
  • 1/2 teaspoon smoked paprika
  • to taste salt
  • to taste black pepper
  • 1 1/2 cups shredded Mexican cheese blend
  • for garnish fresh cilantro, chopped

Equipment

  • 9x13-inch baking dish
  • large skillet
  • cutting board and knife
  • measuring cups and spoons

Instructions

  1. Heat your oven to 375°F and lightly grease a 9x13-inch baking dish so the peppers release easily later.
  2. Set the halved bell peppers cut side up in the dish and bake for 15 to 20 minutes, until they soften slightly. Pre-roasting means they finish tender, not crunchy.
  3. While the peppers roast, warm the olive oil in a large skillet over medium heat. Add the onion and cook for 3 to 4 minutes, stirring now and then, until soft and translucent so the filling tastes sweet, not sharp.
  4. Stir in the garlic and cook about 1 minute, just until fragrant. Watch it closely, since garlic burns fast and turns bitter.
  5. Add the cooked quinoa, black beans, corn, diced tomatoes, cumin, chili powder, smoked paprika, and a few pinches of salt and pepper. Cook 5 to 7 minutes, stirring, until everything is heated through and the flavors blend.
  6. Pull the skillet off the heat and stir in 1 cup of the shredded cheese so it melts into the warm filling and holds it together.
  7. Spoon the filling into the roasted pepper halves, mounding it slightly, then top each with the remaining 1/2 cup cheese.
  8. Return the peppers to the oven and bake 15 to 20 minutes, until the cheese is melted and bubbly and the peppers are fork-tender.
  9. Let the peppers rest 5 minutes so the filling sets, then scatter chopped cilantro over the top and serve.

Tips from the kitchen

  • Cook the quinoa ahead of time or use leftover quinoa to shave 15 minutes off the process.
  • Mound the filling generously; it holds together better than a loose spoonful and looks great on the plate.
  • If your peppers tip over, slice a thin sliver off the rounded bottoms to help them sit flat.

Make it your own

  • Swap in red or yellow bell peppers for a sweeter, milder bite.
  • Use brown rice or cauliflower rice in place of quinoa.
  • Make it vegan by using your favorite dairy-free shredded cheese.

Storing & make-ahead

Store cooled stuffed peppers in an airtight container in the fridge for up to 4 days. Reheat in a 350°F oven for about 15 minutes or microwave individual peppers for 2 to 3 minutes. You can assemble them a day ahead and bake just before serving.

Good to know

Do I need to cook the quinoa first?
Yes. The quinoa should be fully cooked before it goes into the filling, since the short bake time will not cook raw grains through.
Can I freeze these?
Absolutely. Freeze baked, cooled peppers in a single layer, then store up to 3 months. Thaw overnight in the fridge and reheat in the oven.
How do I keep the peppers from getting watery?
Drain the diced tomatoes well and rinse the black beans. Pre-roasting the peppers also releases excess moisture before stuffing.
Can I add meat?
Sure. Stir in a cup of cooked ground beef or turkey with the filling, and reduce the beans slightly to keep the balance.
