About the Ingredients

6 large bell peppers (any color, tops cut off and seeds removed)

Choose peppers that are squat and wide so they stand up easily. Any color works, but red and orange are sweeter.

1 cup (185g) uncooked quinoa, rinsed

Rinse quinoa thoroughly to remove its bitter coating. You can substitute with 2 cups cooked brown rice or farro.

2 cups (480ml) vegetable broth

Use low-sodium broth to control salt. Water works in a pinch, but broth adds more flavor.

1 tablespoon olive oil

Extra-virgin olive oil is great here, but any neutral oil like avocado or canola works too.

1 medium onion, diced

Yellow or sweet onion is best; red onion will be a bit more pungent.

3 cloves garlic, minced

Fresh garlic is ideal, but 1 teaspoon of garlic powder can substitute.

1 can (15 oz / 425g) black beans, drained and rinsed

Rinsing reduces sodium by about 40%. You can use pinto or kidney beans instead.

1 cup (165g) frozen corn, thawed

Frozen corn is convenient and sweet. Fresh corn cut off the cob is even better in summer.

1 can (14.5 oz / 411g) diced tomatoes, undrained

Fire-roasted diced tomatoes add a smoky flavor. If using fresh, chop 2 medium tomatoes and add 1/4 cup water.

1 teaspoon ground cumin

Cumin is essential for that warm, earthy flavor. You can add 1/2 teaspoon smoked paprika for extra depth.

1 teaspoon chili powder

Use a mild chili powder or adjust to your heat preference. Ancho chili powder is a great smoky substitute.

1/2 teaspoon salt

Adjust to taste, especially if your broth or beans are salted.

1/4 teaspoon black pepper

Freshly ground black pepper is best for flavor.

1 cup (120g) shredded cheddar cheese (or Mexican blend)

Sharp cheddar adds a nice tang. For a dairy-free version, use vegan shredded cheese or omit.

Tips & Tricks

• To make the peppers stand up straight, slice a thin sliver off the bottom if needed, but be careful not to cut through.
• If you have leftover filling, serve it as a side dish or wrap it in tortillas for a quick lunch.
• For a crispier top, broil the peppers for the last 2-3 minutes, watching closely to avoid burning.

Step-by-Step Instructions

1. Preheat and Prep

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil or cooking spray. Cut the tops off the bell peppers, remove the seeds and membranes, and set aside.

2. Cook the Quinoa

In a medium saucepan, combine the rinsed quinoa and vegetable broth. Bring to a boil over high heat, then reduce to low, cover, and simmer for 15 minutes, or until the liquid is absorbed. Remove from heat and let stand, covered, for 5 minutes, then fluff with a fork.

3. Sauté Aromatics

While the quinoa cooks, heat olive oil in a large skillet over medium heat. Add the diced onion and cook for 4-5 minutes until translucent, stirring occasionally. Add the minced garlic and cook for 1 minute more until fragrant.

4. Combine Filling

To the skillet, add the cooked quinoa, black beans, corn, diced tomatoes (with their juices), cumin, chili powder, salt, and pepper. Stir to combine and cook for 2-3 minutes until everything is heated through. Remove from heat and stir in 1/2 cup (60g) of the shredded cheese.

5. Stuff the Peppers

Place the hollowed peppers upright in the prepared baking dish. Spoon the quinoa filling into each pepper, packing it gently and mounding it slightly on top. Use all the filling.

6. Top with Cheese

Sprinkle the remaining 1/2 cup (60g) of cheese evenly over the tops of the stuffed peppers.

7. Bake to Perfection

Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, until the peppers are tender and the cheese is bubbly and golden brown. To test for doneness, insert a knife into a pepper – it should slide in easily.

8. Rest and Serve

Remove from the oven and let the peppers rest for 5 minutes before serving. This allows the filling to set and makes them easier to handle. Serve hot, garnished with fresh cilantro if desired.

Delicious Variations

Southwest Style

Add 1/2 teaspoon smoked paprika and 1/4 cup chopped fresh cilantro to the filling, and top with a dollop of sour cream or Greek yogurt.

Mediterranean Twist

Replace the black beans with chickpeas, use feta cheese instead of cheddar, and add chopped Kalamata olives and sun-dried tomatoes.

Spicy Kick

Add 1 diced jalapeño (seeds removed for less heat) to the sauté, and use pepper jack cheese for a fiery finish.
