How to make vegetable lasagna

Begin by preheating the oven to 375°F.

Step #1: Make the filling- To make the filling, put the cooked beans, pine nuts (or substitute cashews or hemp seeds), nutritional yeast, miso, lemon juice, basil, garlic, and chile flakes in a food processor fitted with the ‘S’ blade and process until smooth. Add the spinach or kale and process until well incorporated.

Step #2: Saute the veggies- In a large nonstick saute pan, saute the onion in 2 tablespoons of water until translucent, about 8 minutes, adding more water, 1 tablespoon at a time, if necessary to prevent sticking.

Add the mushrooms, tamari or low-sodium soy sauce, and garlic and saute until the mushrooms are browned. Taste and add more garlic or tamari as desired. Cook until the mushrooms look glazed and there is no more liquid left in the pan.

Step #3: Assemble- To assemble the lasagna, pour 3 cups of marinara sauce into a lasagna pan or 9 x 13-inch pan. Place one layer of the noodles on top of the sauce. Cover the noodles with half of the bean/spinach mixture, then cover the bean mixture with half of the mushroom mixture.

Chef AJ’s vegetable lasagna tips & notes

If you have time, marinate the sliced mushrooms in the tamari or soy sauce for several hours in advance or even the night before to add even more flavor.
Make sure the top layer of noodles is fully covered with sauce to prevent them from drying out.
If you are avoiding all sodium, omit the miso and use balsamic vinegar in place of tamari.
Tamari makes this recipe gluten-free. Soy sauce can be substituted but has gluten.
You can also use lasagna noodles made from hearts of palm. These are available online and at many natural food stores.

Make ahead storing tips

This recipe can be made 24 hours ahead of time and left unbaked. Be sure to cover it well before refrigerating.
When you’re ready to bake it, allow it to sit out on the counter to come to room temperature for 30-60 minutes before baking.
If you want to bake it while it is still cold, add an additional 10 minutes to the cooking time because it is coming directly out of the refrigerator.
Chef AJ says that she hasn’t frozen it before. My bet is that it should freeze well.

To reheat

Heat oven to 350°F. Cover the lasagna pan loosely with foil. Warm until heated through which should take 20-30 minutes depending on the amount of lasagna left in the pan.
You can also reheat individual servings of lasagna in the microwave for about 1 minute.

Good side dishes to serve with vegetable lasagna

Lasagna is perfect for dinner, and there are a number of side dishes that go well with it like the ones listed below.

Crusty bread
Broccoli Salad
Asparagus
Crispy Roasted Brussels Sprouts
Roasted or steamed vegetables
Garden salad
