- 2 cups cubed butternut squash
- 6-10 cloves garlic
- 2 tablespoons fresh thyme leaves
- 2 tablespoons chopped fresh rosemary
- Crushed red pepper flakes
- Kosher salt and black pepper
- 8 slices prosciutto

These ingredients, they’re like a little flavor party. You gotta that olive oil to get everything slick and roasting nicely. The butternut squash and garlic? They’re the stars, getting all sweet and mellow with the heat. Fresh thyme and rosemary add that earthy punch, while the red pepper flakes kick just enough heat to keep you interested.
The prosciutto wraps around the mix, roasting until it’s just crisp. And ricotta? It’s the creamy glue that holds it all together. This pasta wouldn’t be the same without it.
How It All Comes Together Step by Step
Step 1: First, preheat your oven to 400 degrees Fahrenheit. Toss that olive oil, cubed butternut squash, cloves of garlic, fresh thyme, and one tablespoon of that rosemary on a baking sheet. Add a pinch of red pepper flakes, salt, and pepper too.
Step 2: Lay the prosciutto slices around the squash. Pop it in the oven and bake for 20 minutes, then check how that prosciutto is doing. Bake for another 10 to 15 minutes until the squash is tender and perfectly roasted.
Step 3: Next, pop the cooked squash, garlic, and ricotta into a food processor. Puree it up till it’s smooth and silky. Give it a pinch of salt and pepper, cuz hey, you gotta season well.
Step 4: Bring a large pot of salted water to a boil for your pasta. Cook it till it’s al dente according to package directions. Right before you drain, save one cup of that pasta water. It’s gonna help make that sauce perfect.
Step 5: Melt together butter, fresh sage, and the last tablespoon of rosemary in a skillet. Cook until the butter gets a little brown and smells nutty. Stir in your butternut squash puree and half a cup of the pasta water. Keep stirring, then melt in the gouda and parmesan cheeses.
Step 6: Toss in the pasta until it’s all coated with that creamy sauce. If it seems too thick, add a splash more of your reserved pasta water. Then plate it up, top with parmesan and the crispy prosciutto. Twirl it up and dig in!
Valve Hacks You Need to Know
When you’re pressure cooking, the sealing ring is your best friend. Make sure it’s clean and sits right so steam don’t escape before pressure build happens.
Keep an eye on the steam cues. That little steady hiss means everything’s cooking just right. Too much or too little could mean adjustment needed.
Want to speed up release? You can quick release, but watch your fingers and keep the valve pointed away from you. It’s gotta be done safely.
Save some cooking water or broth depth for thinning sauces or adding moisture back after pressure cooking. It’s a secret trick to keep dishes luscious and not dry.

Making It Last All Week Long
Got leftovers? No problem. Store any extra pasta in an airtight container in the fridge. It’s gonna stay tasty for about 3 to 4 days. Also, check out our guide on making pasta last throughout the week to keep it fresher for longer.
When reheating, add a splash of water or broth to loosen up that creamy sauce. It thickens when cold, so this helps bring it back to life.
If you want to freeze, freeze portions without the prosciutto. It freezes well for up to 2 months. Thaw in the fridge overnight before reheating gently on the stove.
For a quick lunch, pack the pasta separate from prosciutto so it keeps that nice crispiness when you’re ready to eat. Just bring a little container of parmesan cheese for topping.
Everything Else You Wondered About
Q1. Can I skip the prosciutto or swap it for something else?
You sure can! Try sun-dried tomatoes as a garnish in step 7 — about ¼ to ½ cup sliced thin. No need to roast them, just sprinkle on top before serving.
Q2. When does the sage get added?
Good catch! Sage is added during the butter melting step before mixing in the sauce. It’s not roasted but gives that warm herbal note to your sauce.
Q3. How do I make the sauce less thick if it’s too heavy?
Use reserved pasta water little by little to thin the sauce until it’s just right. That starchy water adds creaminess without watering down flavor.
Q4. Can I use other cheeses if I don’t have gouda or parmesan?
Sure thing. Gruyere, fontina, or even mozzarella work. Just choose something that melts nicely and has a mild flavor.
Q5. How do I know when the butternut squash is done perfectly?
Look for tender pull when pierced with a fork or knife — it should give easily but not be mushy. Roasting time may vary slightly with your oven.
Q6. Any tips for saving pasta cooking water?
Yep, always scoop the water off before draining pasta fully. Keep it in a heatproof container so you can add back as you toss the pasta for perfect sauce consistency.
