How to make this lentil mushroom loaf
Cook the lentils
Cook your dry lentils according to package instructions. Once all of the water has been absorbed, set them aside to cool for a few minutes before placing them in the food processor.
In the meantime, preheat the oven to 350 °F (175 °C) and line a loaf pan with parchment paper.
Sauté the veggies
Add onion, garlic and mushrooms to a non-stick pan and cook in a splash of water while stirring frequently.
After a few minutes, add the carrot and soy sauce. The latter will add a wonderful savory and deep flavor to your lentil mushroom loaf!
Sauté for a few more minutes until all of the liquid has evaporated.
Combine the ingredients
Add your cooked and slightly cooled lentils to your food processor alongside the sautéed veggies and the rest of the ingredients for the vegan loaf batter.
Pulse a few times to incorporate everything and be sure not to over-process the mixture! It should still be textured and a bit chunky, not smooth and homogenous.
Transfer it to your prepared loaf pan and pack it down firmly to make sure it stays together.
Add the glaze
In a small bowl, whisk together the ingredients for the homemade glaze. Alternatively, you can use ketchup or even BBQ sauce if you like!
Spread it evenly on top of your lentil loaf mixture, then place the loaf pan into the oven.
Bake and enjoy
Bake your lentil mushroom loaf for 45 minutes until the glaze starts to brown on the edges and the loaf is firm in the middle.
Remove the vegan loaf from the oven and set it aside to cool for 10 minutes before taking it out of the pan and cutting it into slices.
Storage & reheating
This lentil mushroom loaf tastes best the day you make it but it’s also super delicious when reheated for a quick lunch or dinner over the next couple of days!
Once completely cooled, store any leftovers in a sealed container in the fridge for up to around 5 days.
Sliced lentil loaf can be frozen when put between parchment paper so that the slices don’t stick together and then put into freezer-safe containers.
When reheating your vegan meatloaf, get as many slices as you like and put them back in the oven for about 8 minutes at 350° F.
Our vegan lentil loaf can be the star at your Thanksgiving table where it can be offered alongside dishes such as:

FAQs & tips
How to prep ahead
You can cook the lentils a few days before making this recipe or just buy canned lentils instead. You can also sauté the veggies and make the glaze ahead of time so that you just need to throw everything together, add the glaze, and bake your lentil mushroom loaf!
Can I use canned lentils?
We’ve made this recipe with canned lentils as well as kidney beans before, yes. You’ll need around 15 ounces or 420 grams of cooked legumes for this recipe.
Be sure that the batter is not too sticky or wet, so drain the sautéed vegetables and lentils well before adding everything into your food processor.
If necessary, use more oats to help soak up the excess liquid!
We also recommend that any veggies you’re using in this vegan meatloaf should be chopped finely or even grated!
Feel free to add other veggies like celery, zucchini or bell peppers in this recipe! Be sure to finely chop and sauté them first.
Adding some liquid smoke or vegan Worcestershire sauce brings out the umami flavor and if you cannot have walnuts, use another nut or ¼ cup tahini instead. If using nut or seed butter, add more oats to achieve the right texture!
You can also cook your lentils in vegetable broth and use spices like sage, fennel or smoked paprika.
