Ingredients

Filling:

2 tablespoons olive oil, divided
1 medium onion, peeled and diced
8 oz of mushrooms, roughly chopped (I use cremini but any mushroom would work)
½ teaspoon salt and ¼ teaspoon black pepper
2 teaspoons dried oregano
¼ teaspoon red pepper flakes (optional)
2 cups of winter squash, 1/2 inch cubes (I use delicata squash, it is a great choice since it does not need to be peeled. Honeynut, butternut, kabocha, or acorn are great options but they need to be peeled for this recipe)
4 cloves of garlic, minced or use a garlic press
8-10 oz baby spinach leaves, torn (you can also use frozen spinach that is thawed and water squeezed out of it)

Sauce & Pasta:

5-6 fresh basil leaves, torn
1 jar of tomato sauce between 24-28 oz (my favorite is Carbone’s roasted garlic)
1¼ - 1½ cups of broth or water (use 1 ½ cups with a 24 oz jar of tomato sauce and 1 ¼ cups with 28 oz jar)
7-8 lasagna noodles (I use Jovial gluten free pasta but any lasagna noodles will work)
6 tablespoons ricotta (nondairy ricotta works great)

To Finish:

¼ cup parmesan cheese, finely grated
Fresh chopped basil for garnish

Directions

To Prep Before Cooking:

Peel and dice your medium onion. Roughly chop the mushrooms. Cube your winter squash and peel it if using a different variety than delicata. Mince your garlic or put it through a garlic press. Tear your spinach into smaller pieces. Tear your 5-6 basil leaves and put them directly into the jar of the sauce. Measure out the salt, black pepper, dried oregano and red pepper flakes (if using) into a little bowl. Measure out your water or broth.

Cooking:

Heat 2 tablespoons of oil in a deep 12 to 14-inch skillet over medium-high. Add onions and mushrooms. Cook for 7-10 minutes until onions begin to brown and mushrooms have softened, stirring occasionally to ensure even cooking.
Add winter squash and season with salt, pepper, oregano, and chili flakes; toss to evenly coat vegetables, and cook for 1-2 minutes. You may need to drizzle just a little oil if the mixture seems dry or is sticking to the bottom.
Lower the heat to low and add the garlic and spinach. Cover to cook until tender, about 1-2 minutes.
Uncover and add the tomato sauce, broth and torn basil, stir to combine, and turn heat back up to medium to bring to a simmer.
Once it is simmering, place the lasagna noodles into the sauce, setting them up like dominos. You may need to break the lasagna in half to fit them on the sides. Gently press the pasta into the sauce; they will slightly overlap, that is what you want. Dollop each tablespoon of ricotta on top of the pasta around the pan.
Cover and reduce heat to low, try not to uncover, and trust the process :). Cook for ~15 minutes, or until pasta is tender. As the pasta cooks it will soak up the liquid and release its starch to thicken the sauce.
Remove cover and top with parmesan cheese. If you desire you can place the pan under the broiler with the grated parmesan for 2-3 minutes to create a crispier cheese topping.
Let the lasagna sit for 10 minutes before serving. Sprinkle with fresh basil and enjoy!

Notes

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.
Freezing: You can also freeze baked lasagna, just be sure to cool it completely and securely cover it. Let it thaw in the fridge and reheat in the oven for 10-15 minutes at 350°. It will keep for up to 2 months in the freezer.
Additions: You can also add 8 oz of ground turkey or chicken. Add the meat right after the mushrooms and cook for 5-6 minutes. Or you could add 1 cup of cooked lentils

Nutrient Highlights

Tomato sauce is loaded with lycopene, a powerful antioxidant with anticancer properties that becomes more bioavailable when cooked.
Spinach adds folate and iron to support cellular health, and mushrooms bring vitamin D and compounds that help regulate hormone functions.
Garlic, onions, and herbs don't just smell amazing—they support your body's natural detoxification and boost your immune system.
Winter squash contributes that beautiful orange color—nature's way of showing its protective properties, packed with carotenoids that help defend your cells. It's an anticancer powerhouse that also supports gut health and reduces inflammation.
Even the parmesan works in your favor—the aging process creates beneficial probiotics for gut health while eliminating lactose, making it easier to digest.
