Vegetable Lasagna

Jump to Recipe

A few years ago when we were in South Africa we went over to my mom's childhood friends home for a home cooked meal and it was honestly one of the best lasagnas I've ever had in my life! It was loaded with all the veggies and a perfect bechamel sauce. I've been futzing with the recipe ever since and finally nailed it. This perfect Vegetable Lasagna is one for the regular rotation!

The beauty of this recipe is that it works with WHATEVER vegetables are in your fridge. I've done it with a combination of zucchini, yellow squash, eggplant, carrots, red bell peppers and mushrooms. The key is just making sure all the veggies are chopped in the same size so they cook evenly! Once they are caramelized and perfect, they get layered with sheets of pasta, béchamel sauce, basil vin, a tomato sauce of your choosing and all the cheese. All that's left to do it bake the lasagna until the cheese is golden and bubbly and EAT. Serve it up with a simple salad, I'm partial to this Kale Vegan Caesar and call it a day!

Ingredients
  

For the bechamel:

  • ½ cup butter
  • ½ cup flour
  • 4 cups milk
  • 1 cup grated parmesan cheese
  • pinch of grated nutmeg
  • Kosher salt and freshly cracked black pepper

For the vegetables

  • 4 tablespoons olive oil
  • 1 yellow onion, diced into ½ inch pieces
  • 2 large carrots, diced into ½ inch pieces
  • 4 cups chopped vegetables (½ inch cube) use any combination of zucchini, yellow squash, eggplant, red bell peppers, mushrooms
  • 24 ounces marinara sauce
  • 1 cup parmesan cheese, grated
  • kosher salt and freshly cracked black pepper

Remaining Ingredients

  • 1 package no-boil lasagna noodles 9 ounces
  • 1 cup grated Parmesan cheese
  • 1 ½ pounds shredded mozzarella cheese
  • 1 recipe basil vinaigrette

Instructions
 

For the béchamel

  • In a medium sized saucepan, melt the butter. Whisk in the flour and cook for just a minute or so. Slowly add the milk and keep whisking. Add the nutmeg, parmesan, salt and pepper whisk. Cook for a few minutes, whisking, until the béchamel has thickened slightly. Set aside to cool. Stir it once in a while so no skin forms on the top.

For the vegetables:

  • Preheat the oven to 375 degrees F.
  • In a large Le Creuset, heat the olive oil, and add the onion and carrot and start to sauté. Once soft, add the remaining chopped vegetables and season with salt and pepper. Cook for 15-20 minutes until starting to caramelize and get soft. Add the marinara sauce and parmesan and stir to combine. Keep over medium low heat.
  • Spray a 13x9 baking pan with cooking spray. Spoon some béchamel thinly on the bottom of the pan. Start with a layer of noodles, a layer of béchamel, some vegetables, a layer of basil vinaigrette and then a layer of a cheese. Repeat layers until you have 3 layers of noodles. On top of the last layer, finish with béchamel and the remaining cheeses. Cover tightly with a greased piece of foil.
  • Bake for 50 minutes, remove foil, increase heat to 450 and bake for 15 minutes more until top is golden brown, cheese is bubbling and the noodles are crisp on the edges. Let sit for 15 minutes before slicing.

Notes

Leftover veggies are easy to incorporate. If you don't have quite enough, just sauté the new/fresh veggies first to release water, then add the already cooked ones to heat through before proceeding.

    Made last night. My first bechamel! Whole family loved.

    One humble suggestion. If you're using either type squash, make sure you cut very thickly before roasting at 425. I about burned down our kitchen. Thankfully had a second large zucchini in reserve to sub in. Roasted that at 350 and turned out fine. Oddly, no issue with the mushrooms or red pepper getting charred.

    Overall though, great recipe. Can not wait to try again.

    Delicious! I think next time the only change I will make is to add roasted garlic to the vegetable mix for a wee bit more flavor there, otherwise the whole family enjoyed this. Used a bit less of the mozarella as my kids don't like super-cheesy dishes.

  3. Made this tonight and it was terrific, I love how you can use whatever veggies you have on hand! I omitted the eggplant and added broccoli, peas, and more mushrooms, (For anyone that needs measurements, I put in 1/2 tsp nutmeg, pepper and salt to the bechamel sauce). Delicious, a great alternative to “classic” lasagna with red sauce! Thanks for sharing, Gaby!

  4. I just made this and loved it! I prepped it and baked it halfway the night before to be a faster weeknight meal. Unfortunately the bechemel separated a bit. I think next time I'd freeze then bake from frozen and see how that does. I roasted butternut squash, zucchini, and grape tomatoes. My toddler thoroughly appreciated how much cheese there was!

    1. love this dish! Just made for the fourth time, each with a different sampling of veggies. I think bell pep and mushrooms is my favorite. I definitely recommend investing in a deep dish 9x13 pan for this.
      My husband requested it for his birthday dinner when I offered to make him anything he wanted!

  5. Oh my goodness. I made this tonight for a couple of girlfriends and we nearly finished the pan! This is so delicious and I will definitely be making again. I added the vegan kale salad you have linked as well and it was a hit!

    1. There should be a pinterest button on the left side of each page where you can pin!! Is it not showing up?
