Ingredient notes
- Brown lentils – I love using lentils as a way to replace ground beef in recipes. It has a similar size and they’re packed with protein and nutrition. (1) They’re also easy to make and don’t require any soaking before hand.
- Mushrooms – Feel free to leave these out if you don’t like them. Mushrooms add an amazing texture and flavor to this lasagna.
- Tofu cashew ricotta – This dairy free ricotta is so delicious and easy to make. You just blend some soaked, raw cashews, firm tofu, lemon juice, garlic powder, olive oil and salt in a food processor.
- Pasta sauce – I use about two jars because I love when lasagna is moist. If you don’t boil your pasta before hand, using two jars of pasta sauce is essential as well. Check the ingredients that it’s dairy free. I don’t bother making my own because I want to keep this recipe as quick and easy as possible.
- Lasagna noodles – Yes, most pre-made, store bought lasagna noodles are vegan. Use whatever brand you’d like: boil or no boil. I used about one box of noodles in this recipe.
- Dairy free cheese – I used Chao slices. Use whatever brand is your favorite. Mozzarella is best.
- Dairy free, unsweetened yogurt (optional) – If you want to add a little more moisture to the lasagna, I love adding in about a cup of dairy free yogurt. Makes the lasagna even more creamy.
Storing tips
To store in the fridge – This will last about a week after it’s been baked. Keep it in an air tight container.
To store frozen – I recommend you don’t bake it if you want to store it in the freezer. Make sure you cover it well with multiple tight layers of aluminum foil, so it doesn’t get freezer burnt.

Substitutions
If you don’t want to use tofu, you can just use all cashews. Increase the amount of cashews to 2 cups.
If you don’t want to use cashews, use only tofu and add a little more olive oil.
To make this gluten free, use gluten free lasagna noodles.
How to cook frozen lasagna
Baking frozen lasagna takes about 90 minutes. You can cook it unthawed, straight from the freezer.
Pre-heat oven to 400 degrees. Make sure the lasagna is covered well with aluminum foil.
Bake the lasagna covered for 60-75 minutes. Remove the foil and continue to bake until the cheese is golden brown and sauce is bubbling. This will be about another 30 mintues.
How long to bake lasagna
Non-frozen lasagna bakes at 350 degrees, covered with aluminum foil, for 45 minutes. Then uncovered for another 10-15 minutes.

How to layer lasagna
- Put a layer of the marinara and lentil sauce at the bottom of the casserole dish. Just enough to cover it.
- Add a layer of noodles. It’s great if they overlap a little
- Add a layer of the dairy free ricotta.
- Add a layer of sauce on top
- Add a layer of shredded dairy free cheese
- Add a layer of noodles
- Continue until the casserole dish is full
- Top with pasta sauce and dairy free cheese
Can you freeze lasagna?
Yes! Lasagna is a great freezer meal. Just follow all the steps and instead of baking, cover it with a freezer friendly lid, or tightly wrapped, multiple layers of aluminum foil.
Do I have to boil lasagna noodles before?
It’s not completely necessary to boil lasagna noodles before, even if they’re no boil. Sometimes I do and when I’m feeling lazy, I don’t. If you choose to not boil the noodles, make sure to use two jars of pasta sauce. Sometimes I add in ½ cup of water too.
