Gluten-Free Vegan Diner Meatloaf with Mushroom Gravy

This gluten-free vegan meatloaf brings all the cozy nostalgia of a classic diner dinner without any animal products or gluten. Brown lentils and toasted walnuts form a hearty, savory base, bound together with gluten-free oats and a flax "egg," then seasoned with smoked paprika, garlic, onion, and fresh herbs for deep, meaty flavor. A tangy tomato glaze caramelizes on top as it bakes, creating crisp, slightly sticky edges that make this loaf irresistible. Ladled generously with a rich mushroom gravy made from sautéed cremini mushrooms, vegetable broth, and a splash of tamari for umami depth, this dish delivers the ultimate comfort food experience. Serve it alongside creamy mashed potatoes to soak up every drop of gravy, plus a simple steamed green vegetable to round out the plate. Perfect for a cozy weeknight dinner or a plant-based Sunday supper, this recipe proves that comfort food classics can be just as satisfying when they're gluten-free and entirely plant-based. It slices neatly, reheats beautifully, and is a great make-ahead option for meal prep.
