Ingredients

For the Stuffed Peppers:

• 4 medium bell peppers (any color), halved lengthwise and seeds removed
• 1 tbsp olive oil
• 1 small onion, finely diced
• 2 cloves garlic, minced
• 1 carrot, finely diced
• 1 celery stalk, finely diced
• 1 cup cooked brown or green lentils (canned, rinsed, and drained, or cooked from dry)
• 1 cup cooked quinoa
• 1 (14.5 oz) can diced tomatoes, undrained
• 1/2 cup vegetable broth
• 1 tsp dried oregano
• 1/2 tsp smoked paprika
• 1/4 tsp black pepper
• Salt to taste
• 2 tbsp fresh parsley, chopped (for garnish, optional)

Step-by-Step Instructions

1. Prepare the Peppers: Preheat your oven to 375°F (190°C) or your air fryer to 350°F (175°C). Lightly brush the inside of the bell pepper halves with a little olive oil and place them cut-side up on a baking sheet (for oven) or in your air fryer basket (you may need to do this in batches for the air fryer).
2. Sauté Aromatics: Heat 1 tablespoon of olive oil in a large skillet or pot over medium heat. Add the diced onion, carrot, and celery. Sauté for 5-7 minutes, until softened and fragrant. Add the minced garlic and cook for another minute until aromatic.
3. Combine Filling: Stir in the cooked lentils, cooked quinoa, diced tomatoes (with their liquid), vegetable broth, dried oregano, smoked paprika, and black pepper. Bring the mixture to a gentle simmer, then reduce heat to low and cook for 5-7 minutes, allowing the flavors to meld and some of the liquid to absorb. Taste and adjust salt as needed. The filling should be moist but not watery.
4. Stuff the Peppers: Carefully spoon the lentil and quinoa filling generously into each bell pepper half. Don’t overfill, but ensure they are packed well.
5. Cook (Oven Method): Place the stuffed peppers on the baking sheet. Bake for 25-30 minutes, or until the peppers are tender-crisp and the filling is heated through and slightly browned on top.
6. Cook (Air Fryer Method): Place 2-3 stuffed pepper halves in the air fryer basket, ensuring they don’t touch too much. Air fry for 20-25 minutes, or until the peppers are tender and the filling is heated through and slightly caramelized on top. You may need to cook in batches.
7. Serve: Garnish with fresh chopped parsley, if desired, and serve hot.

Pro Tips for Success

• Pre-Cook Your Grains & Legumes: For truly quick stuffed peppers, use pre-cooked lentils (canned work great!) and quinoa. You can cook a batch of quinoa at the beginning of the week to save even more time.
• Don’t Overcook the Peppers: Aim for tender-crisp peppers, not mushy ones. They should hold their shape but be easy to cut with a fork. Keep an eye on them, especially in the air fryer, as cooking times can vary.
• Season the Filling Generously: The filling is the heart of this dish. Taste it before stuffing and adjust seasonings. A pinch more salt, a dash of hot sauce, or extra herbs can elevate the flavor significantly.
• Prevent Tipping (Oven Method): If your pepper halves are wobbly, you can trim a tiny bit off the bottom exterior (being careful not to cut through) to create a flat base, or place them snugly in a baking dish to keep them upright.

Variations & Substitutions

• Spicy Kick: Add a pinch of red pepper flakes to the filling with the garlic, or a dash of your favorite hot sauce before serving.
• Extra Veggies: Feel free to add finely diced mushrooms, zucchini, or spinach to the filling along with the other vegetables for added nutrients and texture.
• Grain Swaps: While quinoa is fantastic, you could also use cooked brown rice, farro, or even couscous for a different texture.
• Bean Power: For an even heartier filling, stir in a 1/2 cup of black beans or kidney beans (rinsed and drained) along with the lentils.
• Cheesy Topping (Non-Vegan Option): If not strictly vegan, a sprinkle of dairy-free shredded mozzarella or a plant-based parmesan alternative can be added during the last 10 minutes of baking for a gooey topping.

Serving Suggestions

These Quick Vegan Lentil & Quinoa Stuffed Bell Peppers are a complete meal on their own, offering a perfect balance of protein, carbs, and vegetables. However, they pair wonderfully with a simple side salad dressed with a light vinaigrette, or a slice of crusty whole-grain bread to soak up any extra sauce. They are ideal for a satisfying weeknight dinner, a healthy meal prep lunch, or even a lighter, yet hearty, option for a casual gathering.

Storage & Reheating

• Refrigerator: Leftover stuffed peppers can be stored in an airtight container in the refrigerator for up to 3-4 days.
• Freezer: To freeze, allow the cooked peppers to cool completely. Wrap individual peppers tightly in plastic wrap, then aluminum foil, or place them in a freezer-safe container. They can be frozen for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
• Reheating: Reheat in the microwave until warmed through, or in an oven preheated to 350°F (175°C) for 15-20 minutes, or until hot. For the air fryer, reheat at 300°F (150°C) for 8-10 minutes, checking periodically.

Frequently Asked Questions

Can I make the filling ahead of time?

Absolutely! The lentil and quinoa filling can be prepared up to 2-3 days in advance and stored in an airtight container in the refrigerator. When ready to cook, simply stuff the peppers and proceed with baking or air frying.

What kind of bell peppers work best?

Any color bell pepper works beautifully! Red, yellow, and orange peppers tend to be sweeter, while green peppers have a slightly more robust, earthy flavor. Choose firm, unblemished peppers of similar size for even cooking.

My peppers are falling over in the air fryer. How can I prevent this?

Air fryer baskets can be tricky. Try to choose bell peppers with flatter bottoms. If they still tip, you can carefully place a small piece of crumpled aluminum foil around the base of each pepper to stabilize it, or cook fewer peppers at a time to give them more space.
