Frequently Asked Questions

Yes! Slice the loaf, then freeze separated by parchment. Reheat slices in the oven or air fryer until warm through.

Absolutely. Prepare and shape it in the pan, cover, and refrigerate up to 24 hours before baking.

Brown or green lentils are ideal because they hold their shape and have a hearty texture. Red lentils are too mushy for this recipe.

Make sure the lentils are drained well, pulse half the mixture, and allow the loaf to rest before slicing.

Definitely—finely chopped mushrooms, bell peppers, or grated zucchini work well. Just ensure they’re sautéed and moisture reduced.

Cook the Lentils

  • Rinse 1 cup dried brown lentils under cold water.Add to a pot with 2 ½ cups liquid (you used half vegetable broth, half water — perfect). Bring to a boil, then reduce heat to low. Simmer 17-20 minutes, until tender but not mushy.
    Drain well and let them cool slightly before mixing.

Sauté the Vegetables
