Cook the Lentils
1

Sauté the Vegetables

  • Add onion, garlic, carrot, and celery. Sauté until soft and fragrant, about 5–7 minutes.

  • In a large bowl, combine lentils, sautéed vegetables, chopped walnuts, oats, tomato paste, soy sauce, vinegar, thyme, smoked paprika, and flax egg.

  • Season with salt and pepper.

  • Mash slightly with a potato masher or pulse in a food processor for a cohesive but textured mixture.

Shape and Bake

  • Preheat oven to 375°F (190°C).

  • Line a loaf pan with parchment paper or lightly oil it.

  • Press the mixture into the pan, smoothing the top.

Make and Add the Glaze

  • Mix glaze ingredients together in a small bowl.

  • Spread evenly over the top of the loaf.

Bake

Serving Suggestions

  • Serve with mashed potatoes, sautéed greens, or a fresh herb salad.

  • Great with mushroom gravy or vegan brown gravy on the side.

Variations

  • Add mushrooms to the sauté for more umami

  • Swap walnuts for pecans or sunflower seeds

  • Use lentils and rice combo for extra heartiness

Pairing Suggestions
10
