Our Best Tips for Vegetable Lasagna

We know making the best lasagna can seem overwhelming, but, with these tips, ensure that your veggie-packed lasagna comes out perfect every. single. time.

  • If you’re looking for healthy substitutes, we suggest swapping out ricotta using equal parts cottage cheese and whipping it up in a food processor for a smooth, silky filling! You can also use whole wheat noodles!

  • Short on time? Swap out your noodles (and skip the first step!) for no boil noodles!

  • Want to make it gluten-free? Look for gluten free noodles and satisfy everyone OR swap out the noodles entirely and use this Lasagna Stuffed Zucchini Boat recipe!

  • While jarred marinara in this recipe saves time, if you have a little extra, we suggest making your own, Homemade Marinara.

  • We chose budget-friendly, hearty vegetables for this recipe but, you can make it your own and adjust the vegetables…such as diced eggplant, Tuscan kale, and bell peppers based on the season. Keep in mind that anything with a high water content will need to be cooked first to avoid a soggy lasagna later!

  • Our favorite tip: Make Ahead! Follow steps 1- 7, up until it’s assembled, and then freeze! When you bake it later, you’ll need to take it out of the freezer ahead of time and add 20-30 minutes to the covered baking time.

What to Serve with Vegetarian Lasagna

A crowd pleasing dish for the holidays is here and it goes well alongside almost any menu! Our favorite sides are a classic Caesar Salad, Kale Caesar, or a Simple Italian Salad. And we could never forget something to soak up all that delicious sauce and veggies like Focaccia, Garlic Bread, or Pull Apart Cheese Bread. If you’re looking for a heartier accompaniment, we like to serve easy-to-make roasted meats such as Whole Roast Chicken with Carrots or the Perfect Roast Turkey Recipe. For the holidays, it goes beautifully alongside a Roasted Garlic Honey Baked Ham or Prime Rib with Roasted Garlic and Horseradish Cream Sauce.

How to Make Vegetable Lasagna

Follow these step-by-step instructions for how to make a simple and cozy casserole with layers of tender veggies, rich tomato sauce, herby ricotta, and gooey, bubbling cheese:

  1. Prep the lasagna noodles! Simply add your noodles to boiling salted water and cook al-dente according to the package. Don’t skip the step of salting the water – this can make a big impact on flavor! Pro Tip: although it’s hard not to oil your noodles when they come out to avoid sticking, don’t! This might cause the sauce not to stick. When ready to assemble, run them gently under warm water and they’ll come apart.

  2. Cook the vegetable mixture! This process will soften and lightly brown the vegetables as well as reduce the water content in them, so you’ll have a lasagna that will hold together without being watery! Onions and garlic develop flavor while the zucchini, yellow squash, spinach, and mushrooms beef up the mixture!

  3. Mix up the ricotta layer! Garlicky, herby ricotta gets held together by the eggs resulting in a smooth, delicious filling.

  4. Assemble and bake! Start by adding a thin layer of sauce down, followed by the lasagna noodles, ricotta mixture, vegetable mixture, and eventually the sauce. Repeat two times ending with a healthy serving of mozzarella. Bake covered for 30 minutes then remove the top and bake an additional 30 until the top is golden brown and bubbly!

Vegetable Lasagna

  • Serves: 12
  • Prep Time:  45 min
  • Cook Time:  1 hr 10 min
  • Calories: 305

Ingredients

  • 3 teaspoons sea salt
  • 1 (16-ounce) box lasagna
  • 2 tablespoons extra-virgin olive oil
  • 1 medium yellow onion, diced
  • 4 garlic cloves, minced
  • 8 ounces cremini mushrooms, sliced
  • 1 medium zucchini, diced
  • 1 medium yellow squash, diced
  • 3 cups loosely packed baby spinach, roughly chopped
  • ⅓ cup fresh basil, chopped
  • 15 ounces ricotta cheese
  • 1/2 cup grated Parmesan, plus more for serving
  • 2 large eggs
  • 1 teaspoon garlic powder
  • 1/4 teaspoon freshly cracked black pepper
  • 1 (32-ounce) jar marinara sauce
  • 16 ounces low moisture mozzarella, grated (about 4 cups)

Method

  1. Preheat the oven to 400°F with a rack in the center position. Line a rimmed sheet pan with foil.

  2. Fill a large pot with water and add 2 teaspoons of the salt. Place over high heat and bring to a boil. Add the lasagna and cook until al dente according to the package instructions. Drain.

  3. Heat the olive oil in a large skillet over medium heat. When the oil is glistening, add the onions and cook until beginning to soften, about 5 minutes. Add the garlic and cook, stirring, until fragrant, about 1 minute more. Add the mushrooms, zucchini, squash, and remaining teaspoon of salt and cook until slightly softened, about 3 minutes. Add the spinach and cook until wilted and most of the liquid has evaporated, about another 5 minutes. Turn off the heat.

  4. Meanwhile, in a medium bowl combine the basil, ricotta, Parmesan, eggs, garlic powder, and pepper.

  5. Spread ¼ cup of the sauce in a 9 x 13-inch baking dish. Add an even layer of lasagna (see Note), then top with ⅓ of the ricotta mixture, spreading out in an even layer. Top with ⅓ of the vegetable mixture. Sprinkle with ¾ cup of the grated mozzarella. Repeat with the remaining sauce, lasagna, ricotta mixture, veggies, and mozzarella.

  6. Cover the baking dish loosely with aluminum foil and place on the prepared sheet. Bake for 30 minutes, then remove the foil and bake, uncovered, for about another 20 minutes, or until bubbling and lightly browned.

  7. Remove the lasagna from the oven and let cool for at least 5-10 minutes before serving with Parmesan alongside.

Note: When ready to use, simply run the noodles under warm water to separate.

    Would this work just as well with cottage cheese instead of ricotta? I prefer the texture.

    We haven't tested with cottage cheese but if you prefer it, it should be ok.
