Key Ingredients

• 1 cup dry brown lentils (or 2.5 cups cooked)
• 2 tablespoons ground flaxseed mixed with 5 tablespoons water
• 2 tablespoons olive oil
• 1 cup mushrooms, finely chopped
• 1/2 cup onion, diced
• 1/2 cup carrots, diced
• 1/2 cup bell pepper, diced
• 4 cloves garlic, minced
• 1/2 cup rolled oats
• 1/2 cup breadcrumbs
• 1/4 cup tomato sauce
• 1 teaspoon fresh thyme, salt, and black pepper to taste
• 8 ounces sliced mushrooms (for gravy)
• 2 cups vegetable broth (for gravy)
• 2 tablespoons all-purpose flour (for gravy)

Step-by-Step Instructions

1. Preheat your oven to 350°F and line a 9×5-inch loaf pan with parchment paper.
2. In a small bowl, whisk together the ground flaxseed and 5 tablespoons of water; set aside for 15 minutes to thicken into a flax egg.
3. Boil the lentils in 2.5 cups of water for 15-20 minutes until softened, then drain thoroughly.
4. Heat olive oil in a large skillet over medium heat and sauté the onions, garlic, chopped mushrooms, carrots, and bell peppers for 6-8 minutes until tender.
5. In a food processor, pulse the cooked lentils, sautéed vegetables, flax egg, oats, breadcrumbs, tomato sauce, and thyme 3-4 times until the mixture starts to stick together but remains textured.
6. Transfer the mixture to the prepared loaf pan, press down firmly, and bake for 45-50 minutes until the edges are browned and the center is firm.
7. While the loaf bakes, sauté the sliced mushrooms for the gravy in a saucepan until browned, then whisk in flour and cook for 1 minute.
8. Gradually pour the vegetable broth into the saucepan, whisking constantly, and simmer until the gravy reaches your desired thickness.
9. Remove the lentil loaf from the oven and let it cool in the pan for 15 minutes to set before slicing and serving with the warm mushroom gravy.
