Pro Tip: Streamline Butternut Squash Prep
Sometimes, handling and cutting a whole butternut squash can be quite a challenge due to its firm flesh. If you’re looking to save time and effort, don’t hesitate to opt for pre-cut butternut squash cubes, readily available in the produce section of most grocery stores. This simple shortcut can significantly speed up your preparation process without compromising on the quality or flavor of your lasagna. Look for fresh, vibrant orange cubes for the best results!

Crafting Your Butternut Squash Lasagna: A Step-by-Step Guide
Making this butternut squash lasagna follows the same satisfying process as crafting a classic lasagna, with a few delightful enhancements. The key to a truly successful and well-structured lasagna lies in meticulous preparation. Ensure each component is ready and perfectly flavored before you even begin to assemble the layers. This thoughtful approach guarantees an evenly cooked, incredibly delicious result where every bite is a burst of flavor and texture.
The foundation of this incredible dish rests on four perfectly prepared elements:
- Rich Red Sauce: The heart of the lasagna, brimming with vegetables and savory notes.
- Creamy Cheese Sauce: A luscious blend that adds moisture, tang, and cheesy goodness.
- Tender Lasagna Noodles: The essential architectural base for each layer.
- Flavorful Vegetables: Butternut squash and mushrooms, integrated into the red sauce for convenience and depth.

Mastering the Art of Layering: Tips for Each Component
Each individual component of this butternut squash lasagna is prepared with care, and understanding the nuances of each layer will ensure your final dish is nothing short of spectacular. Here are our top tips for perfecting every part of your lasagna:
The Robust Red Sauce: Depth and Flavor Infusion
The red sauce is more than just a coating; it’s a critical flavor driver. It’s absolutely essential to simmer your red sauce for a good 15-20 minutes after bringing it to a boil. This extended simmering time allows all the wonderful flavors from the onion, garlic, red wine, balsamic vinegar, and Italian seasonings to meld beautifully, creating a deep, complex sauce. Crucially, adding the butternut squash and mushrooms directly into the sauce allows them to tenderize and absorb all these incredible flavors, contributing to their initial cooking process. Do not skip this simmering step – it’s where the magic happens!
When you begin layering, be generous with the red sauce over your lasagna noodles. A sufficient amount of sauce provides the moisture needed to help the noodles cook fully and evenly in the oven, preventing them from drying out and ensuring a perfectly tender pasta experience.
The Creamy Cheese Sauce: Light, Tangy, and Rich
Our unique cheese sauce strikes a perfect balance between classic richness and a lighter, fresher profile. We combine part ricotta cheese for its traditional creamy texture with part Greek yogurt, which introduces a delightful tang and lightens the overall feel of the sauce. Mozzarella and Parmesan cheeses contribute their distinct melting qualities and savory depth, while fresh thyme and garlic powder infuse the mixture with aromatic notes. Simply combine all these ingredients in a bowl and mix until well blended. The goal is a smooth, spreadable consistency that can be evenly distributed across each layer of your lasagna.
The Tender Lasagna Noodles: Al Dente Perfection
The preparation of your lasagna noodles is paramount. Boil them until they are al dente – meaning they still have a slight bite to them. This is a critical step because the noodles will continue to cook and soften significantly as the lasagna bakes in the oven. Overcooked noodles will result in a mushy lasagna, which is something we definitely want to avoid.
Equally important is the post-boiling treatment. After straining the water from your cooked noodles, immediately spread them out flat, ideally on a baking sheet or clean counter space, and lightly drizzle them with a bit of olive oil. Gently toss or separate them. This simple trick is a lifesaver, preventing the noodles from sticking together in a clump, making them much easier to handle and layer smoothly into your casserole dish.


Butternut Squash Lasagna 101: Your Questions Answered
Here are some frequently asked questions and essential tips to help you master your butternut squash lasagna:
Is Butternut Squash a Healthy Addition?
Absolutely! Butternut squash is an incredibly healthy and nutrient-dense root vegetable. It’s an excellent source of beta-carotene, which your body converts into Vitamin A, crucial for vision and immune function. It also provides a significant amount of Vitamin C, potassium, and dietary fiber. Including butternut squash in your lasagna not only adds a wonderful sweetness and vibrant color but also boosts the nutritional profile, making this dish a truly wholesome choice for a healthy carbohydrate.
Can I Use Butternut Squash Puree Instead of Cubes?
While this recipe was specifically developed and tested using cubed butternut squash for its distinct texture and visual appeal within the layers, you can certainly experiment with butternut squash puree. If you choose to use puree, we recommend stirring a few tablespoons of it into each layer of red sauce after you’ve spread it over the noodles. This will integrate the flavor throughout the lasagna. Keep in mind that using puree will result in a smoother, less textured lasagna, and you might need to adjust the sauce consistency slightly if the puree adds too much moisture.
How Do I Store Leftover Butternut Squash Lasagna?
Proper storage is key to enjoying your delicious lasagna for days to come. Once your butternut squash lasagna has finished baking, allow it to cool completely at room temperature. This is important to prevent condensation, which can make your leftovers soggy. After it’s cooled, transfer individual servings or larger sections into an airtight container. Store it in the refrigerator for up to 5 days, ensuring maximum freshness and flavor.
To reheat the lasagna: For best results, let your refrigerated lasagna come to room temperature for about 20-30 minutes before reheating. Then, place it in an oven preheated to 350ºF (175ºC) and bake until the cheese is bubbling and the center is thoroughly warm, typically around 20-30 minutes for a single slice or longer for a larger portion. You can also reheat individual slices in the microwave, though the oven provides a superior texture.
Can I Freeze This Butternut Squash Lasagna?
Yes, butternut squash lasagna freezes beautifully, making it an excellent meal prep option! Allow the baked lasagna to cool entirely after it comes out of the oven. For individual portions, cut the lasagna into slices before wrapping. For a whole pan, cover it tightly first with plastic wrap, then with a layer of heavy-duty aluminum foil to prevent freezer burn. Label with the date. Your lasagna can be stored in the freezer for up to 3 months, ready for a convenient future meal.
To reheat from frozen: For best results, transfer the frozen lasagna to the refrigerator overnight to thaw. Then, let it come to room temperature before reheating in an oven preheated to 350ºF (175ºC) until heated through and golden brown. If reheating directly from frozen, keep it covered with foil and bake at 350ºF (175ºC) for 1 hour or more, then uncover and bake until bubbling and heated through. A food thermometer should read 165°F (74°C) in the center.
Can I Assemble This Lasagna Ahead of Time?
Absolutely! This butternut squash lasagna is a fantastic make-ahead meal. You can assemble the entire lasagna, up to the point of baking, cover it tightly with plastic wrap and then foil, and store it in the refrigerator for up to 24 hours. When you’re ready to bake, remove it from the refrigerator and let it sit at room temperature for about 30-60 minutes before baking as directed. You might need to add an extra 10-15 minutes to the initial baking time if it’s still quite cold.
What Should I Serve with Butternut Squash Lasagna?
This hearty lasagna is a complete meal on its own, but it pairs wonderfully with a few simple sides. A crisp green salad with a light vinaigrette provides a refreshing contrast to the richness of the lasagna. Garlic bread or crusty artisan bread is perfect for soaking up any extra sauce. For a more substantial meal, consider roasted asparagus or steamed green beans.

Ingredients
Red Sauce
- 2 tablespoons olive oil
- 1 medium yellow onion, minced
- 1 tablespoon minced garlic
- 1/2 cup red wine
- 3/4 teaspoon salt, separated
- 2 tablespoons balsamic vinegar
- 28 oz. crushed tomatoes
- 15 oz. can diced tomatoes
- 2 tablespoons Italian Tuscan Seasoning
- 8 oz. crimini mushrooms, chopped
- 2 cups butternut squash, peeled and cubed
Cheese Sauce
- 1/2 cup 2% plain Greek yogurt
- 16 oz. ricotta cheese
- 1 cup mozzarella, separated
- 1 cup parmesan, separated
- 1 tablespoon fresh thyme
- 1 teaspoon garlic powder
Other Ingredients
- 16 oz. lasagna noodles
Instructions
- Preheat your oven to 375ºF (190ºC). Lightly spray a 9×13-inch casserole dish with non-stick cooking spray and set it aside.
- Heat a large pot over medium-high heat. Add the olive oil.
- Once the olive oil is shimmering, add the minced yellow onion and 1/4 teaspoon of salt to the pot. Sauté the onion until it becomes soft and translucent, which typically takes about 3-4 minutes.
- Add the minced garlic to the pot and continue to sauté with the onion for another 3-4 minutes, until fragrant. Be careful not to burn the garlic.
- Deglaze the pot by pouring in the red wine. Use a spatula to scrape any browned bits of garlic and onion from the bottom of the pot, incorporating all that flavor into the sauce.
- Add the remaining salt, balsamic vinegar, crushed tomatoes, diced tomatoes, Italian Tuscan Seasoning, butternut squash cubes, and chopped crimini mushrooms to the pot. Stir all the ingredients well to combine. Bring the sauce to a gentle boil.
- Once the sauce has reached a boil, reduce the heat to low, cover the pot, and let the sauce simmer for 15-20 minutes. This allows the flavors to deepen and the butternut squash to begin tenderizing.
- While the sauce is simmering, bring a separate large pot of generously salted water to a rolling boil. Carefully add the lasagna noodles to the boiling water and cook according to package directions until they are al dente. They should be firm but pliable.
- Strain the water from the cooked noodles. To prevent them from sticking, immediately spread the noodles out flat on a baking sheet or clean surface and drizzle them lightly with olive oil. Gently separate them if needed.
- In a medium bowl, combine the ricotta cheese, 1/2 cup of mozzarella cheese, 1/2 cup of Parmesan cheese, fresh thyme, and garlic powder. Stir all ingredients together until well combined and smooth.
- Assemble the Lasagna: Begin by spreading about 1/2 cup of the red sauce evenly on the bottom of your prepared 9×13-inch casserole dish. Lay a single layer of cooked lasagna noodles over the sauce. Using a spatula, spread about 1/2 cup of the creamy cheese sauce evenly over the noodles. Follow with another 1/2 cup of the red sauce spread on top of the cheese layer. Repeat this layering process – noodles, cheese sauce, red sauce – until the casserole dish is almost full.
- Ensure your final layer is a generous coating of the red sauce. Then, sprinkle the remaining Parmesan and mozzarella cheese evenly over the top of the red sauce, creating a delicious cheesy crust.
- Cover the lasagna dish tightly with aluminum foil and place it in the preheated oven. Bake for 35 minutes.
- After 35 minutes, carefully remove the tin foil from the casserole dish. Return the lasagna to the oven and turn the oven setting to broil (watch it closely!). Broil for an additional 3-5 minutes, or until the cheese on top is beautifully melted, bubbly, and golden brown.
- Remove the lasagna from the oven. This step is crucial: let it rest for 10-15 minutes before cutting. This allows the layers to set and prevents the lasagna from falling apart. After resting, cut the lasagna into 9 pieces and serve warm.
