Your Simple Ingredient Checklist
Alright, so you gonna need 3 pounds of butternut squash. Make sure it's quartered, seeded, peeled, and then diced into little half inch cubes about 8 cups total. You want it just right to roast up tender and sweet.
Grab about 3 tablespoons of grapeseed oil or olive oil, whichever you got. For the creamy sauce, 4 cups of milk works best, either 2% or whole milk. Plus a couple sprigs of fresh rosemary and sage to give that herbal pop.

Don't forget 1 tablespoon minced garlic to give a little kick. You also need 4 tablespoons unsalted butter and 4 tablespoons all-purpose flour for the white sauce base. For the pasta part, 9 sheets of no-boil lasagne noodle makes layering easy.
Finish it off with 1 and ⅓ cups of freshly grated Parmesan cheese, a cup of heavy cream, and about half a teaspoon of salt to pull all those flavors together nice.
The Full Pressure Cooker Journey
Step one, get your oven heated to 400 degrees Fahrenheit. Toss your diced squash with 2 tablespoons of that oil you got and spread it out on a baking sheet. Roast it for about 25 to 30 minutes till it's tender and starting to brown. Set that aside.
Next, warm the milk low and slow with the rosemary and sage in it. You wanna see it steaming but not boiling, then take it off the heat and let it steep. Strain out those herbs before you use the milk.
Now over medium heat, melt your remaining tablespoon of oil with the butter in a saucepan. Toss in the garlic and cook for just 30 seconds. Whisk in the flour and cook that for a minute to take the raw edge off.
Slowly add your herb-infused milk little by little, whisking constantly so it thickens nice and smooth. After about 5 to 7 minutes it'll look creamy and perfect. Season with salt and pepper to taste.
Time to build your lasagna layers in a 9 by 13 inch pan. Start with a thin sauce layer so the noodles don't stick. Then lay down 3 sheets of pasta, a third of your roasted squash, more sauce, sprinkle Parmesan, and drizzle cream. Repeat twice more, ending with sauce, Parmesan, and cream on top.
Cover it with foil and bake at 375 degrees for 25 minutes. After that, pull off the foil and bake uncovered for another 15 to 20 minutes till everything's golden and bubbly.

When it's out, let it cool down for about 10 minutes so it sets up softly. Then you're ready for that first rich, creamy bite. Yum.
Easy Tweaks That Make Life Simple
- You can roast the squash the day before to cut down active cooking time
- Use pre-minced garlic to save chopping stress in the kitchen
- Skip fresh herbs and use 1 teaspoon of dried rosemary and sage instead when you're tight on time
- Swap heavy cream for half and half to lighten it up a bit
- Double the sauce and freeze leftovers for a ready-to-go meal later
The Flavor Experience Waiting for You
Every bite kinda melts in your mouth with that tender pull of roasted butternut squash. The squash is softly sweet from roasting but brings this earthy vibe that hugs you warm like an old friend. The cheesy Parmesan adds that sharp edge that cuts through the creamy layers real good.
The creamy sauce is infused with rosemary and sage so you feel these little bursts of earthiness and herb kisses on your tongue. Garlic sneaks in just right to bring a little warmth but never overpowers the gentle flavors.
You notice the layers coming together with pasta that's silky but not mushy cause of that careful pressure cooker timing. It's a cozy dinner that makes you wanna curl up and savor every single piece, gosh it's comfy and satisfying to the core.
Making It Last All Week Long
If you got leftovers, just let the lasagna cool to room temp before you stash it in an airtight container. It'll keep well in the fridge for about 4 days, perfect for a quick reheat when you're hungry.
For longer sides, you can freeze the lasagna. Cover it tightly in foil or plastic wrap, then place it in a freezer-safe box or bag. It'll last up to 3 months and thaw in the fridge overnight when you wanna dig in again.
When reheating either from fridge or freezer, warm it covered in the oven at 350 degrees till heated through. You get that creamy, saucy goodness back without drying it out. The pressure cooker done a great job making this dish shine whenever you want.
Your Most Asked Questions Answered
Can I skip roasting and cook the squash straight in the pressure cooker? You could, but roasting adds a nice caramelized flavor you won't get otherwise. The pressure cooker makes it tender fast, but roasting first gives better taste. Check out other tips and pressure cooker recipes on our site.
What if I don't have fresh rosemary or sage? No prob! Dried herbs work too. Just use about a teaspoon each since they're more concentrated and add them when warming the milk. For herbal cooking inspiration, see our recipes with dried herbs.
How do I know when to do a quick release? When the cooking timer beeps, carefully flip the valve to quick release steam. Do it slow so you don't get messy splatters, then open the lid once float valve drops.
Can I make this vegan? You can try swapping out dairy for plant milks like oat or almond, and use vegan butter and cheese. It won't be exactly the same but still pretty tasty.
What if my pressure cooker doesn't have a float valve? Just follow the manufacturer instructions for pressure build and release. Usually a timer or indicator light will guide you safely through. Refer to our pressure cooker tips for more ideas.
Any tips for layering when using no-boil noodles? Spread sauce evenly and don't overload with liquid or veggies so noodles cook right. The creamy sauce helps soften the pasta good during baking.
