- Crispy, golden breadcrumb topping. You can’t have a creamy baked pasta without breadcrumbs on top, case closed.
Let’s run through some of the components! –>
Butternut Squash Alfredo Sauce
Roasting the butternut squash is the first order of business. Grab your sharpest knife and break down a small-ish squash into about 3 cups 1-inch cubes.
Toss the cubes with a little olive oil + s&p and they’re ready for the oven. Let ’em roast at a high temp of 400F 15-20 minutes until they’re easily pierced with a knife or fork.
From there, it’s time to start building the sauce. We’re going to make a basic alfredo from a butter/flour roux, a little half and half, milk, Parmesan, and a grating of fresh nutmeg (KEY for building flavor – don’t skip the nutmeg!)
Set 1 cup of the roasted butternut squash cubes aside and give the remaining squash + alfredo sauce a whirl in the blender until smooth.
Then return to the stove and stir in the spinach + reserved squash cubes until the spinach is wilted. It’s gonna be lusciously creamy, cheesy, and goooood.
As I mentioned before, you can definitely use any shape of pasta if that’s what you have on hand. I will say, however, I definitely prefer fettuccine for this particular recipe. It just holds the sauce perfectly.
Fold al dente cooked fettuccine pasta into the sauce and then spread it all in your sturdiest casserole dish.
Then go crazy with the breadcrumbs + a little sprinkle of herby parsley, and heck, why not more Parmesan if you’re feelin it??
Bake until bubbly then DIG IN while it’s hot, creamy, and cheesy. ♥
I have a lot of comfort food favorites this time of year but wow, I think this alfredo just got bumped to the top of the list.
It’s pure INSANITY what the butternut squash does to the sauce! I’d just drink it if pasta wasn’t such a good sauce vehicle.
Guarantee you’re gonna love it. Guarantee if you don’t, you should send it on over my way.
MORE creamy, cheesy dinners you should be adding to your dinner rotation!
