No Pasta Butternut Squash Lasagna is my new obsession, and trust me, you’re going to love this lighter, veggie-packed twist on comfort food! I created this recipe on a busy Tuesday when I had an extra butternut squash sitting on my counter, begging to be transformed into something delicious.
Henry was skeptical at first (he’s a pasta traditionalist), but after one bite, he was completely sold. Isabella, Emma, and Noah devoured their portions and actually asked for seconds which, if you have kids, you know is basically winning the lottery!
What makes this recipe so special is how the butternut squash becomes tender and almost melts in your mouth, while the prosciutto adds that perfect salty, savory touch. The layers of gooey mozzarella cheese and that hint of pesto bring everything together beautifully. Plus, it’s naturally gluten-free without even trying, and you won’t miss the pasta one bit. If you’re looking for more creative ways to enjoy squash, you’ll also love my invisible butternut squash spinach lasagna.

Ingredients You’ll Need for Butternut Squash Lasagna
- Olive oil spray keeps everything from sticking and adds a touch of flavor
- 1½ lbs butternut squash peeled and sliced thin (this is your “pasta”)
- 8 thin slices prosciutto adds that salty, savory element (optional for vegetarians)
- 16 oz shredded mozzarella because you can never have too much cheese

- 1 teaspoon dried oregano brings in those classic Italian vibes
- Chili pepper flakes just a pinch for serving if you like a little heat
Ingredient Tips and Substitutions
The butternut squash is the star here, so make sure you slice it evenly between 1/8 and 1/4 inch works best. Too thick and it won’t cook through properly; too thin and it might get mushy.
If you can’t find prosciutto or want to keep this vegetarian butternut squash lasagna, just leave it out! You’ll need to add a little salt to the squash layers since the prosciutto provides most of the saltiness.
For the cheese, mozzarella works perfectly because it melts so beautifully, but feel free to experiment with gouda or provolone if that’s what you have. The pesto adds amazing flavor, but in a pinch, you could use a simple marinara sauce instead.
How to Make This Easy No Pasta Butternut Squash Lasagna
Step 1: Preheat your oven to 400°F. This temperature is perfect for getting the squash tender while browning the cheese on top. Grab a 9×13 inch baking dish and give it a good spray with olive oil on the bottom and sides this prevents sticking and makes cleanup so much easier.
Step 2: Time to prep your squash! Peel your butternut squash and slice it into thin rounds or planks between 1/8 and 1/4 inch thick. I find using a sharp knife or a mandoline makes this much easier. (Just watch your fingers if you use a mandoline I learned that lesson the hard way!)
Step 3: Now comes the fun part building your lasagna! Start with a layer of squash on the bottom of the baking dish, overlapping the slices slightly like shingles on a roof. Add 4 slices of prosciutto torn into pieces, then cover everything with a generous blanket of mozzarella cheese.
Step 4: For your second layer, add more squash slices, then brush on the pesto. This step is so important because the pesto adds incredible flavor throughout the dish. Top with more mozzarella.
Step 5: For your final layer, add the remaining squash, the last 4 slices of prosciutto, and finish with the rest of the mozzarella. Sprinkle the grated parmesan on top, add the dried oregano, and give it one more spray of olive oil. This helps the top get beautifully golden.
Step 6: Bake for 40-45 minutes. Keep an eye on it you might need to cover it with foil for the last 20 minutes if the top is browning too quickly. The squash should be fork-tender when it’s done.
Step 7: This is the hardest part let it cool for 10 minutes before slicing! I know it’s tempting to dig right in, but letting it rest helps everything set up so your slices hold together nicely. Top with chili pepper flakes if you like a little kick.
Pro Tips for Perfect Butternut Squash Lasagna Every Time
After making this easy butternut squash lasagna countless times (seriously, it’s on our weekly rotation now), I’ve picked up a few tricks that make all the difference.
First, don’t skip peeling the squash properly. Any tough skin left on will stay tough even after baking, and nobody wants that in their lasagna.
Second, if you’re short on time, many grocery stores now sell pre-cut butternut squash! This is a total game-changer on busy weeknights. Yes, it costs a bit more, but the time saved is worth every penny.
Third, layer your cheese generously but evenly. You want cheese in every bite, but you also don’t want it all pooling in one corner.
Also, that 10-minute resting time isn’t a suggestion it’s essential! The first time I made this, I cut into it immediately and all the layers slid apart. Patience pays off here.
If you’re making this ahead, assemble everything the night before and keep it covered in the fridge. Just add about 10 extra minutes to the baking time since it’ll be starting cold.
Storage and Reheating Your Butternut Squash Lasagna
This lasagna stores beautifully, which is why I often make it for Sunday meal prep. Let it cool completely, then cover tightly with plastic wrap or transfer individual portions to airtight containers.
In the refrigerator, it’ll keep for up to 4 days. I actually think it tastes even better the next day once all the flavors have had time to meld together!
To reheat, I prefer using the oven at 350°F for about 15-20 minutes until it’s heated through. The microwave works in a pinch (about 2-3 minutes on high), but the oven keeps the texture better.
You can also freeze this! Wrap individual portions tightly in plastic wrap, then in foil, and freeze for up to 3 months. Thaw in the fridge overnight before reheating.
Delicious Variations to Try
Once you’ve mastered the basic no pasta butternut squash lasagna, there are so many fun ways to switch it up!
For a white sauce version, skip the pesto and make a simple béchamel sauce with butter, flour, and milk. Layer it between the squash for a super creamy lasagna.
Want more veggies? Add layers of sautéed spinach, mushrooms, or even thinly sliced zucchini between the squash layers.
For a completely vegetarian no pasta lasagna, leave out the prosciutto and add crumbled goat cheese or ricotta for extra protein and creaminess.
If you’re following the Ottolenghi-style approach, try adding toasted pine nuts and fresh herbs like basil or sage between the layers.
You can also experiment with different pestos sun-dried tomato pesto or arugula pesto both work wonderfully here.
What Makes Butternut Squash So Good for You
One of my favorite things about this no pasta butternut squash lasagna is that it’s actually really good for you! Butternut squash is loaded with vitamin A, which is amazing for your skin and eyes. It’s also got plenty of fiber to keep you full and satisfied.
Plus, by swapping out the pasta, you’re cutting down significantly on carbs while still getting that hearty, satisfying feeling you crave from lasagna. The squash adds natural sweetness that balances perfectly with the salty prosciutto and savory cheese.
Serving Suggestions
This easy butternut squash lasagna is hearty enough to be a main dish on its own, but I love serving it with a simple side salad dressed with balsamic vinaigrette. The acidity cuts through the richness perfectly.
Garlic bread is always a hit in our house (even though we’re already going “no pasta,” we still love our bread!). A crusty baguette or some homemade focaccia works beautifully for soaking up any extra cheese.
For a complete Italian-inspired meal, serve it alongside some roasted Brussels sprouts or green beans with garlic.
FAQs About This Recipe
Can I Use a Different Type of Cheese in This Butternut Squash Lasagna Recipe?
Yes! While mozzarella is my go to because it melts so perfectly, you can absolutely use other cheeses. Gouda adds a smoky flavor, provolone is slightly sharper, and fontina is incredibly creamy. You could even mix different cheeses for a more complex flavor profile.
Is It Necessary to Use Prosciutto in This Recipe?
Not at all! The prosciutto adds a wonderful salty, savory element, but this recipe works beautifully without it. If you’re making a vegetarian version, just remember to season your squash layers with a bit of salt and maybe add some extra oregano or Italian seasoning for flavor. You could also substitute with crispy bacon if that’s more your style.
Can I Prepare This Butternut Squash Lasagna in Advance?
Absolutely, and I actually recommend it! Assemble the entire lasagna, cover it tightly with plastic wrap, and refrigerate for up to 24 hours before baking. When you’re ready to cook, just remove it from the fridge, let it sit at room temperature for about 15 minutes, then bake as directed, adding maybe 5-10 extra minutes to account for the cold start.
How Can I Make This Dish Spicier?
There are several ways to add more heat! The easiest is to increase the amount of chili pepper flakes on top. You could also add diced jalapeños or red pepper flakes between the layers. For a smoky heat, try adding a pinch of smoked paprika or chipotle powder to each layer. I sometimes mix some red pepper flakes right into the pesto before spreading it on.
Why This Recipe Works for Busy Families
As a mom of three, I need recipes that are both delicious and realistic for weeknight dinners. This no pasta butternut squash lasagna checks all the boxes. Yes, there’s some slicing involved, but once everything is in the pan, the oven does all the work.
