Step 1

Preheat your oven to 350°F (175°C). Lightly grease a loaf pan or line it with parchment paper for easy removal.

Step 2

Cook the lentils according to package instructions until tender. Drain and set aside to cool slightly.

Step 3

Heat the olive oil over medium heat. Add the onion, garlic, carrot, and celery. Sauté for 5-7 minutes until softened.

Step 4

In a mixing bowl, mash about half of the cooked lentils with a fork or potato masher, leaving some texture.

Step 5

Add the sautéed vegetables, oats, breadcrumbs, flax egg, tomato paste, soy sauce, Dijon mustard, thyme, oregano, salt, and pepper to the mashed lentils. Mix well until combined.

Step 6

Press the mixture into the prepared loaf pan, smoothing the top with a spatula.

Step 7

Whisk together the ketchup, maple syrup, and balsamic vinegar. Spread the glaze over the top of the lentil loaf.

Step 8

Bake for 40-45 minutes, or until firm and golden on top. Let it cool for about 10 minutes before slicing.

Step 9

Slice and serve warm with your favorite sides.
