  • gluten-free, 
  • and soooo delicious!

Recipe Prep

This recipe uses cooked red lentils as the base, so I recommend cooking the lentils up to two days before making your vegan lentil loaf. This will really cut down on the time needed to make the loaf.

Lentils are so easy to cook, too. You don’t need to soak them (although you can), and they just need about 20-25 minutes on the stovetop to transform them into tender, little morsels that are chock-full of plant-based protein and nutrition.

You’ll notice that this recipe uses red lentils which are even more tender than green or brown lentils. I like to pre-cook the red lentils the day before I make this recipe. Then, making the lentil meatloaf is as easy as combining the cooked lentils with the other ingredients.

Recipe Steps

Step One

Once you have your cooked red lentils, the next step to making the perfect Vegan Lentil Loaf is to sautés your vegetables, including onion, mushrooms, garlic, and spinach.

Step Two

Divide the cooked mixture between two loaf pans.

This recipe makes two loaves, one of which can be frozen and then de-frosted and baked at a later date. Each one will only make about 4 servings, though, so you might want to cook them both at the same time, depending on how many servings you need.

Step Three

Bake and serve!

A lentil oat loaf makes the ideal holiday meal because you can prep and bake it the day before, giving you more time to enjoy with your family and friends. Cooking and chilling the loaf the day before also makes it easier to slice when you’re ready to serve.

Slice the loaf and re-heat the plates in a 350 degree oven until warmed through.

Recipes Tips & Substitutions

  • Be sure to use certified gluten-free rolled oats if you plan to serve this dish to gluten-free friends or family.
  • Red lentils are ideal for this recipe; don’t use brown or green lentils.
  • For low sugar diets, use a prepared ketchup that doesn’t have added sugars. You could also use a prepared BBQ sauce (see my list of the best gluten-free sauces).
