Four Seasons Lasagna

So, this vegan Four Seasons Lasagna is a bit of a project, but trust me, it’s totally worth it! We’re talking layers of mouthwatering roasted veggies like tomatoes, spinach, cauliflower, eggplant, onions, garlic, and mushrooms all nestled in between those lasagna noodles. And to tie it all together, a creamy Bechamel sauce, and buttery, breadcumbs sprinkled on top for a delectable crunch.

Recipe tips

When it comes to this tasty lasagna recipe, we are going roast those veggies first to really amp up the flavor. And there’s no need to boil those pasta noodles beforehand, they’ll cook up perfectly right in the lasagna as it bakes.

Now, instead of using cheese, we’re going to whip up a creamy, “cheesy”, Bechamel sauce that’s made with soy milk. You can swap it out with another plant milk if you prefer, just make sure it’s plain and unsweetened.

Oh, and here’s the secret ingredient for that cheesy flavor: nutritional yeast, or as we cool folks call it, “nooch”. It’s this super tasty deactivated yeast that adds a savory, cheesy, umami kick to your dishes. Plus, it’s a hit in the vegan cooking world because it’s packed with protein. Can’t go wrong with that, right?

  1. OMG! This is the recipe I was searching for! My in-laws are coming over this weekend, and I need a vegan (they are not vegan) dinner idea that will totally impress them! Quick question though, they can only have gluten-free food, so I’ll be using gluten-free pasta, but can I make the bechamel sauce gluten-free too?

    1. Hi Melinda!
      You can definitely make the Bechamel sauce Gluten-free, by substituting the flour with cornstarch. Cornstarch is a great thickener but you have to use 1/2 as much cornstarch as you would flour.
      To make GF Bechamel for the lasagna, bring 3 cups of plant-based milk to a simmer. Make a slurry, by mixing 3 tbsp cornstarch with 3 tbsp water and mix. Pour the slurry into the milk and cook, stirring, over medium heat until thickened and bubbly. Add the remaining sauce ingredients and stir.
      I hope your in-laws love it!
