    Butternut Squash Lasagna with Kale and Mushrooms ... a delicious, seasonal vegetarian lasagna recipe that's bursting with vegetables and perfect for any fall occasion. Serve it for a unique Thanksgiving or Christmas dish that everyone will love! | Hello Little Home

    Ingredients

    You can find the ingredients for this fall veggie lasagna at any grocery store! Here's what you'll need:

    • Veggies - This recipe is made with a delicious combination of butternut squash, button mushrooms, and kale. The squash is roasted, and the mushrooms and kale are sautéed. You will also need some olive oil, garlic, crushed red pepper flakes to prepare the vegetables.
    • Ricotta Filling - You'll combine ricotta cheese (use full fat for the best flavor) with mozzarella cheese (shred it yourself for the creamiest results), parmesan cheese, and an egg (which helps hold the lasagna together) to make the creamy filling.
    • Béchamel - Layers of homemade béchamel (white sauce) makes this baked pasta extra creamy, and the sauce is very easy to make. You'll need butter, all-purpose flour, whole milk, and nutmeg.
    • Noodles - Of course, you'll need some lasagna noodles.
    • Cheese - The assembled lasagna is topped with another layer of mozzarella before baking.

    This recipe is vegetarian and nut free.

    You'll Also Need

    You'll need a large baking sheet to roast the squash, plus a frying pan to cook the other veggies and make the béchamel sauce. Grab a large bowl to mix the ricotta filling together, along with a deep 9 x 13-inch baking dish to cook the lasagna.

    How to Make Butternut Squash, Kale, and Mushroom Lasagna

    This vegetarian Butternut Lasagna does take a little more effort than most of my recipes, but it's worth it (especially for special occasions)! You'll find a detailed recipe card below, but here's a quick overview of the steps:

    1. Prep veggies. You'll start by roasting the butternut squash. While that cooks, you'll sauté the mushrooms, then you'll add the garlic and crushed red pepper flakes, followed by kale and a little water. Cover the pan, then cook until the kale is tender.
    2. Mix ricotta filling. While the veggies cook, stir together the ricotta, mozzarella, parmesan, egg, salt, and pepper for the cheese filling.
    3. Make white sauce. Melt the butter in a large skillet, then whisk in the flour until smooth. Continuing to whisk, add the milk. Simmer the sauce until it's thickened then season with nutmeg, plus salt and pepper to taste.
    4. Assemble the lasagna. Once all the components are ready and the noodles are cooked, you'll layer everything together, ending with a layer of mozzarella.
    5. Bake. Cover the lasagna with foil, then bake until it's hot and bubbly. Remove the foil, then continue cooking until the cheese on top has browned.

    Okay, after all that hard work, your mouthwatering Butternut Squash Lasagna is ready to eat. You are going to love each and every bite!

    PRO TIP: If you're making this Butternut Squash and Kale Lasagna for a big meal, assemble it the day before, cover the pan, then refrigerate it overnight. The next day, remove the lasagna from the refrigerator about 30 minutes before baking. Keep in mind, that you may need to add a little extra cooking time.

    Storage

    Store any leftovers in an airtight container in your refrigerator. Rewarm gently in your microwave before eating.

    Serving Suggestions

    This lasagna makes a wonderful fall or winter meal for special occasions and Sunday dinners. However you serve it, it's sure to be a treat! I like pairing this recipe with a simple side, like Roasted Vegetables, a Kale and Brussels Sprout Salad, or Garlic Bread.

    Instructions

    Prepare veggies:

    • Preheat oven to 425°F (220°C). Spray a baking sheet with nonstick spray.
    • Place butternut squash on baking sheet and drizzle with 1 tablespoon olive oil. Season generously with salt and pepper, then stir to coat squash with oil and seasonings.
    • Roast squash until tender and lightly browned, flipping once (about 30 to 40 minutes).
    • Meanwhile, heat 2 teaspoons olive oil in a large skillet over medium high heat. Add mushrooms to pan and cook until lightly browned. Season with salt and pepper.
    • Stir in garlic and pepper flakes; cook until fragrant, about 30 seconds. Then mix in kale, stir well, then add ¼ cup water and cover pan.
    • Reduce heat to medium low and cook until kale is tender and water is evaporated (about 5 minutes).
    • Reduce oven heat to 375°F (190°C). Wipe out pan, and set veggies aside until ready to use.

    • Whisk in flour and cook for 2 minutes, stirring constantly.
    • Slowly whisk in warm milk. Bring mixture to a boil, then reduce heat to simmer.

    • Whisk in nutmeg, then season with salt and pepper to taste.

    Assemble lasagna:

    • Spray a 9 x 13-inch pan with nonstick spray.
    • Spread ¾ cup béchamel sauce over bottom of pan, then top with 3 lasagna noodles.
    • Cover noodles with ½ of the ricotta. Top ricotta with ½ of the vegetables, then ¾ cup béchamel sauce.
    • Add another layer of noodles, the remaining ricotta, then the remaining vegetables. Top with ¾ cup béchamel sauce.
    • Top sauce with remaining 3 noodles, followed by the rest of the béchamel sauce. Sprinkle with 1 cup mozzarella cheese.
    • Cover lasagna tightly with foil, then bake at 375°F (190°C) for 45 minutes or until hot and bubbly.
    • Remove foil and bake lasagna until cheese is lightly browned, about 15 minutes.
