- 3 cloves garlic, minced
- 1 1/2 cups walnuts, finely chopped
- 1 cup rolled oats (use gluten-free if preferred)
- 2 tablespoons ground flaxseed
- 6 tablespoons water (for flax egg)
- 1/4 cup nutritional yeast
- 2 tablespoons soy sauce or tamari
- 1 teaspoon smoked paprika
- 1/2 teaspoon dried thyme
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt

- 1/2 cup tomato paste
- 2 tablespoons maple syrup
- 1 tablespoon apple cider vinegar
- 1 teaspoon smoked paprika
- 1/2 teaspoon garlic powder
- Pinch of salt
Instructions
-
Preheat oven to 350°F (175°C). Line an 8x4 inch loaf pan with parchment paper or lightly grease it.
-
Rinse lentils under cold water. In a medium saucepan, combine lentils and 2 1/2 cups water or vegetable broth. Bring to a boil, then reduce heat and simmer uncovered for 20-25 minutes until lentils are tender and most liquid is absorbed. Drain excess liquid and set aside to cool.
-
Prepare flax egg by mixing ground flaxseed with 6 tablespoons water in a small bowl. Let sit for 5-10 minutes until gel-like.
-
Heat olive oil in a skillet over medium heat. Sauté chopped onion for 5-7 minutes until soft and translucent. Add minced garlic and cook for 1-2 more minutes until fragrant. Remove from heat.
-
In a large bowl, combine cooked lentils, onion and garlic mixture, chopped walnuts, rolled oats, nutritional yeast, soy sauce, smoked paprika, thyme, salt, pepper, and flax egg. Mix well until the mixture is moist and holds shape when pressed. Add more oats if too wet or a splash of water if too dry.
-
Transfer mixture into the prepared loaf pan, pressing firmly to create an even surface.
-
Whisk together all tomato glaze ingredients in a small bowl until smooth. Spread evenly over the loaf's surface.
-
Bake for 45-50 minutes until the loaf is firm and the glaze is slightly caramelized.
-
Let cool in the pan for 10-15 minutes before lifting out with parchment paper. Slice into 6-8 pieces.
-
Serve warm or store in an airtight container in the refrigerator for up to 5 days. Reheat for a quick, protein-rich meal.
-
Optional: Pair with steamed greens, roasted vegetables, or a fresh salad for a complete, balanced meal.
