    Butternut Squash Lasagna

    Without a doubt, butternut squash is one of my favorite fall vegetables! When the weather starts to get chilly, I love to make savory comfort foods. Butternut squash lasagna is a flavorful and delicious alternative to traditional lasagna. Instead of a tomato sauce, my butternut squash lasagna recipe combines layers of roasted butternut squash puree, cashew cheese sauce, and a variety of vegetables. 

    Not only is butternut squash lasagna a great make-ahead weeknight meal, but it's perfect for the holidays. Sweet, moist, and nutty-tasting, the flavor of butternut squash is similar to sweet potatoes.

    Also, you get more servings per fruit than you might with other squash varieties because it's so dense. And, since butternut squash is in season, it is also economical this time of year. 

    WHAT ARE THE BENEFITS OF BUTTERNUT SQUASH? 

    According to Healthline, one cup (205 grams) of cooked butternut squash provides:

    • Calories: 82
    • Carbs: 22 grams
    • Protein: 2 grams
    • Fiber: 7 grams
    • Vitamin A: 457% of the Reference Daily Intake (RDI)
    • Vitamin C: 52% of the RDI
    • Vitamin E: 13% of the RDI
    • Thiamine (B1): 10% of the RDI
    • Niacin (B3): 10% of the RDI
    • Pyridoxine (B6): 13% of the RDI
    • Folate (B9): 10% of the RDI
    • Magnesium: 15% of the RDI
    • Potassium: 17% of the RDI
    • Manganese: 18% of the RDI

    As you can see, butternut squash is low in calories but loaded with essential nutrients.

    Aside from the vitamins and minerals listed above, it's also a good source of calcium, iron, phosphorus, and copper.

    Although I love a tomato-based Vegan Lasagna, butternut squash lasagna has a sweet and savory flavor, enhanced by the other layers in the recipe. 

    CUTTING A BUTTERNUT SQUASH FOR BUTTERNUT SQUASH LASAGNE RECIPE

    How to cut butternut squash

    Similar to other winter squash, butternut squash has a rugged, tough exterior. In my opinion, the easiest way to cut it is to slice it into equal slices and then cut around each piece removing the hard skin. 

    Then, cut the squash into similar-sized pieces so all the pieces roast equally, and then I roast the butternut squash with the shallots and garlic. 

    Once roasted and cooled, blend the roasted butternut squash, shallots, garlic, salt, nutmeg, and milk.

    WHAT INGREDIENTS ARE IN BUTTERNUT SQUASH PUREE?

    • Butternut Squash
    • Shallots
    • Garlic
    • Nutmeg
    • Salt
    • Oat Milk (or plant milk of choice)

    THE MUSHROOM/SPINACH LAYER FOR BUTTERNUT SQUASH LASAGNA

    In a separate skillet, saute onions, mushrooms, fresh sage, and Italian seasoning. 

    CHEESY CASHEW BASIL CHEESE LAYER FOR THE LASAGNA RECIPE

    While the butternut squash roasts in the oven, the cashew basil cheese sauce is made in a high-speed blender. 

     CASHEW BASIL CHEESE INGREDIENTS?

    • Raw Cashews 
    • Vegetable Broth
    • Fresh Lemon Juice
    • Garlic Powder
    • Onion Powder
    • Nutritional Yeast 
    • Basil (fresh is best)

    ADDITIONAL INGREDIENTS/GARNISH: 

    • Vegan Parmesan Cheese
    • Paprika
    • Basil
    • Sage

    HOW TO LAYER THE BUTTERNUT SQUASH LASAGNA

    butternut squash lasagna recipe

    Begin with a 9 X 13 pan, and spread a thin layer of butternut squash puree. Also, pour ¼ cup of vegetable broth on the top of the butternut squash puree to prevent it from sticking. 

    For the next step, place cooked lasagna noodles slightly crossing over each other on top of the butternut squash puree and vegetable broth in the bottom of the pan. 

    Now, add a thin layer of cashew basil cheese, spreading with a spatula, covering the noodles, followed by a layer of spinach and mushroom mixture. And then top with butternut squash puree. 

    Layer 2 Butternut squash lasagna

    Continue the process by adding more noodles, followed by cashew basil cheese, mushroom/spinach mixture, and butternut squash puree until all the ingredients are gone. Then, sprinkle with Vegan Parmesan Cheese, fresh sage, and basil. 

    COOKING, FREEZING, AND REHEATING BUTTERNUT SQUASH LASAGNA

    First, cover the lasagna with aluminum foil and cook for 40 minutes at 375 degrees.

    Next, remove the cover and cook for an additional 10 minutes until browned.

    I also suggest recovering the lasagna once it's removed from the oven and allowing it to set up for about 10 minutes before servings. The paprika, although optional, adds beautiful color and a smoky flavor.

      Do you have instructions for freezing and cooking from frozen? The titled section only has cooking instructions. Similar to reheating any lasagna from frozen I presume? Thanks! Can’t wait to try.

        Hi Lindsey, I freeze individual pieces and completely thaw before reheating in a 350-degree oven, cover, and reheat for 25-30 minutes.

      I made this for company (and to freeze a portion of two for Thanksgiving dinner) and it was well loved. Even my husband who rarely tries anything I prepare said it was "really good". I used no cook oodles and added a bit more liquid with good results. Thanks again Kathy!

        Hi Anna, usually shy of a=one package of lasagna noodles. However, it does depend on the size of your pan. You want to overlap the noodles slightly as you place them in the pan. Generally, I only use as many as needed for 2 layers, which usually ends up with a few leftover ones at the end. I hope you enjoy the recipe.
