Why This Recipe Works

The blend of lentils and walnuts provides a high-protein, plant-based filling that’s both hearty and nutritious. Lentils add a meaty texture, while walnuts contribute a satisfying crunch. The dish comes together quickly, making it practical for busy evenings.

Stuffed peppers are versatile—you can customize the filling with different herbs or spices. Baking the peppers ensures they become tender without losing their structure. This recipe also stores well, so leftovers stay flavorful for days.

Ingredients

Makes 4 stuffed peppers.

  • 4 large bell peppers (any color), tops cut off and seeds removed
  • 1 cup cooked brown or green lentils
  • 1/2 cup walnuts, chopped
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 1 tsp dried oregano
  • 1 tsp smoked paprika
  • 1/2 cup tomato sauce
  • 1 tbsp olive oil
  • 1/4 tsp salt
  • 1/4 tsp black pepper
  • 1/4 cup fresh parsley, chopped (optional, for garnish)

Equipment

  • Baking dish
  • Large skillet
  • Knife and cutting board
  • Mixing bowl

Instructions

1. Preheat oven to 375°F (190°C). Lightly grease a baking dish and place the prepared bell peppers inside, cut side up. Choose peppers with flat bottoms so they stand upright.

2. Sauté onion and garlic. Heat olive oil in a skillet over medium heat. Add onion and garlic, cooking until soft and fragrant, about 3-4 minutes. Stir frequently to prevent burning.

3. Combine filling ingredients. Add cooked lentils, walnuts, oregano, smoked paprika, salt, and black pepper to the skillet. Stir in tomato sauce and cook for another 2-3 minutes until well combined. For extra flavor, toast the walnuts lightly before adding.

4. Stuff the peppers. Spoon the lentil-walnut mixture into the bell peppers, packing gently. Leave a little space at the top to prevent spillover.

5. Bake for 25-30 minutes until peppers are tender. Cover the baking dish with foil. Test doneness with a fork—it should pierce easily. Remove foil and bake for another 5 minutes if you prefer a crispier top.

6. Garnish and serve. Sprinkle with fresh parsley before serving. A sprinkle of nutritional yeast adds a cheesy flavor if desired.

Tips for Better Results

  • For a spicier kick, add a pinch of red pepper flakes to the filling.
  • Swap walnuts for pecans or almonds if preferred.
  • Avoid overcooking the peppers—they should be tender but still hold their shape.

Variations

Cheesy Version

Top with shredded mozzarella or vegan cheese during the last 5 minutes of baking.

Quinoa Addition

Mix in 1/2 cup cooked quinoa for extra texture and protein.

Serving and Storage

Serve with a side of mixed greens or crusty whole-grain bread for a complete meal. Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave.
