Sauce and Meat
- 14 ounces Italian chicken sausage (casing removed)
- 1 tsp extra virgin olive oil
- 1/2 large onion, chopped
- 3 cloves garlic, minced
- 1 28-oz can crushed tomatoes
- 2 tbsp chopped fresh basil
- Salt and black pepper, to taste
Butternut Squash
- 1 large butternut squash (peeled, at least 3 lbs), sliced into 1/8” thick rounds
Cheese Mixture
- 1 cup part-skim ricotta cheese
- 1/4 cup Parmigiano Reggiano or grated Parmesan cheese
- 2 tbsp chopped parsley
- 1 large egg
Other
- 16 oz shredded part-skim mozzarella cheese (about 4 cups total)
- Brown Sausage and Make Sauce: In a large deep nonstick skillet, heat the olive oil and brown the Italian chicken sausage, breaking it up with a wooden spoon, until fully cooked, about 5 minutes. Add chopped onions and minced garlic; cook until softened, about 2 minutes. Stir in crushed tomatoes, fresh basil, and season with salt and black pepper to taste. Simmer the sauce on low heat, covered, for 15 to 20 minutes to develop flavors.
- Prepare Butternut Squash Slices: While the sauce simmers, peel the butternut squash and slice into 1/8 inch thick rounds using a quality spiralizer, mandoline, or a sharp knife. Take care when slicing to ensure even thickness for proper layering and cooking.
- Preheat Oven: Set the oven temperature to 375°F (190°C) to preheat while assembling the lasagna layers.
- Make Ricotta Cheese Mixture: In a medium bowl, combine the ricotta cheese, grated Parmesan, chopped parsley, and the egg. Mix well until thoroughly blended for a creamy, flavorful cheese layer.
- Assemble Lasagna Layers: In a deep 9×12 inch casserole dish, spread 3/4 cup of the prepared sausage tomato sauce evenly on the bottom. Arrange 12 rounds of butternut squash slices to cover the sauce layer. Spread 3/4 cup of the ricotta cheese mixture over the squash, then sprinkle 1 cup of shredded mozzarella cheese, and top with 1 cup of the tomato sauce. For the second layer, repeat: 12 more butternut slices, 3/4 cup ricotta mixture, 1 cup mozzarella, and 1 cup sauce. The third layer consists of 12 slices of butternut squash and the remaining 1 1/2 cups of sauce. Cover the assembled dish with foil to prevent drying out during baking.
- Bake Covered: Place the covered lasagna in the preheated oven and bake for 30 minutes to allow the layers to meld and the squash to soften.
- Bake Uncovered to Reduce Moisture: Remove the foil carefully and continue baking the lasagna uncovered for an additional 30 minutes. This step helps evaporate excess moisture for the perfect texture.
- Top with Remaining Cheese and Finish Baking: Sprinkle the remaining mozzarella cheese on top of the lasagna and bake for another 5 minutes, or until the cheese is melted, bubbling, and golden brown.
- Rest and Serve: Allow the lasagna to stand for 5 to 10 minutes after baking to set before slicing into 8 pieces and serving warm.
Notes
- Use a sharp mandoline, spiralizer, or very sharp knife to slice the butternut squash thinly and evenly for best results.
- If butternut slices are large, you can cut them in half to better fit and cover the casserole dish in each layer.
- This lasagna can be prepared ahead of time and refrigerated before baking.
- Letting the lasagna rest after baking helps it hold its shape when cut.
