This Vegan Lentil Meatloaf is a hearty, Tex-Mex-inspired twist on classic comfort food. Made with lentils, walnuts, mushrooms, and bold spices, it’s packed with flavor and perfect for a plant-based main dish. Topped with a tangy BBQ glaze, this loaf pairs beautifully with creamy mashed potatoes and roasted vegetables.
Add lentils to a pot of salted boiling water and reduce to a simmer. Cook for 15-20 minutes until tender. Drain and set aside.
Mix the ground flaxseed with the water and set aside to thicken.
Add the butter, oil, or broth to a large skillet over medium low heat. Sauté the garlic, onion, mushrooms, bell pepper and celery until tender. Season with the Worcestershire, salt, pepper, smoked paprika and chili powder. Transfer to a paper towel lined plate to drain excess moisture.
Add walnuts to a food processor and pulse until minced, but not mushy. Add in the cooked veggies, flax egg and lentils and pulse until it’s well combined, but not mushy.
Transfer to a bowl and combine with the breadcrumbs, chiles, and 2/3 cup of the sauce. Add additional breadcrumbs if the mixture feels too wet.
Transfer to a lined or greased loaf pan, and top with 1/3 cup of the remaining sauce. Cover and Bake at 375 for 45-60 minutes until golden brown on the edges.
Remove from the oven and let the loaf rest for at least 10 minutes. Drizzle with spicy mustard and use a knife to decoratively spread the mustard.
Slice into 1” thick pieces and serve hot, with extra sauce on the side if desired.
