Ingredients

• 1 cup brown lentils, rinsed and drained
• 2 ½ cups vegetable broth
• 1 cup finely chopped mushrooms (cremini or button mushrooms)
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup rolled oats
• ½ cup breadcrumbs (use gluten-free if needed)
• 2 tablespoons ground flaxseed mixed with 5 tablespoons water (flax egg)
• 2 tablespoons tomato paste
• 2 tablespoons soy sauce or tamari
• 1 teaspoon dried thyme
• 1 teaspoon smoked paprika
• ½ teaspoon black pepper
• ½ teaspoon salt
• For the glaze:
• ½ cup ketchup
• 2 tablespoons maple syrup or brown sugar
• 1 tablespoon apple cider vinegar
• ½ teaspoon smoked paprika

Equipment

• Medium saucepan
• Large mixing bowl
• Skillet or frying pan
• Measuring cups and spoons
• Loaf pan (8×4 inches)
• Mixing spoon or spatula
• Oven

Instructions

1. Cook the lentils: In a medium saucepan, combine the rinsed lentils and vegetable broth. Bring to a boil, then reduce to a simmer and cook uncovered for about 25-30 minutes, until the lentils are tender but not mushy. Drain any excess liquid and set aside to cool slightly.
2. Prepare the flax egg: In a small bowl, mix the ground flaxseed with water. Let it sit for 5-10 minutes until it thickens to a gel-like consistency.
3. Sauté the vegetables: Heat a skillet over medium heat. Add a splash of oil or a little water for oil-free cooking. Sauté the chopped onion and garlic until translucent and fragrant, about 3-4 minutes. Add the mushrooms and continue cooking until they release their moisture and become soft, about 5-6 minutes. Remove from heat.
4. Mix the meatloaf base: In a large mixing bowl, combine the cooked lentils, sautéed vegetables, rolled oats, breadcrumbs, tomato paste, soy sauce, dried thyme, smoked paprika, salt, black pepper, and flax egg. Mix thoroughly with a spoon or your hands until the mixture is well combined and holds together when pressed.
5. Preheat the oven: Preheat your oven to 375°F (190°C). Lightly grease your loaf pan or line it with parchment paper for easy removal.
6. Shape and bake: Transfer the mixture into the loaf pan and press it down firmly to create an even surface.
7. Prepare the glaze: In a small bowl, whisk together the ketchup, maple syrup (or brown sugar), apple cider vinegar, and smoked paprika.
8. Glaze the meatloaf: Spread the glaze evenly over the top of the meatloaf.
9. Bake: Place the loaf pan in the oven and bake for 45-50 minutes, or until the edges are firm and the top is slightly caramelized.
10. Cool and serve: Allow the meatloaf to cool in the pan for 10-15 minutes before slicing. This helps it set and makes slicing easier.

Tips & Variations

For a gluten-free version, substitute the breadcrumbs with gluten-free breadcrumbs or crushed gluten-free crackers.

Add finely grated carrots or zucchini to the mixture for extra moisture and nutrition.

Try topping your meatloaf with a layer of vegan cheese before baking for a melty, indulgent finish.

You can swap lentils for cooked quinoa or black beans for a different protein profile. Experiment with spices like cumin or chili powder for a southwestern twist.

If you love a smoky flavor, add a few drops of liquid smoke to the mixture.

Leftovers make great sandwiches or crumbled over salads for a protein boost. You can also freeze the baked meatloaf in slices for quick reheating later.
