Step-By-Step Instructions
- Roast the squash (425°F/220°C, 20 minutes). Toss squash with olive oil, ½ tsp salt, ¼ tsp pepper. Spread on a sheet pan; roast until tender and caramelized on the edges.
- Boil the pasta. Cook in salted water until just shy of al dente. Reserve 1 cup (240 ml) pasta water; drain.
- Build the sauce & toss. In a large skillet over medium-high, brown sausage 4–5 minutes, breaking up. Add onion, garlic, sage, remaining salt and pepper; cook 2–3 minutes. Stir in broth and milk. Simmer 2 minutes, then add roasted squash, spinach, and pasta. Toss, adding ½–¾ cup pasta water until glossy. Off heat, fold in Parmesan and lemon juice. Adjust salt/pepper. Serve hot with more cheese.
Pro Tips & Variations
- Creamy without cream: The starch in pasta water + Parmesan makes a silky sauce—add water gradually until it coats.
- Use frozen squash: Thaw, pat dry, and roast on a hot pan so it caramelizes instead of steaming.
- Make it spicy: Add red pepper flakes with the garlic or use spicy chicken sausage.
- Veg-boost: Sub kale for spinach (sauté 2 minutes longer).
- Budget note: Skip fresh herbs and use dried sage; buy block Parmesan and grate it.
- Meal prep: Roast squash and brown sausage 2 days ahead; reheat in the skillet with broth.
Serving Suggestions
- Garlic bread or a simple arugula salad with lemon and olive oil.
- Add a side of roasted green beans or broccoli.
Storage & Reheating
- Refrigerate: 3–4 days in an airtight container.
- Freeze: Up to 2 months; sauce may separate slightly—stir in a splash of broth when reheating.
- Reheat: Skillet over medium with 2–4 tbsp water/broth, 3–5 minutes; or oven 350°F (175°C) covered 10–15 minutes; or microwave 60–90 seconds, stirring halfway.
- Food safety: Cool within 2 hours; reheat leftovers to 165°F (74°C).
Troubleshooting
- Sauce too thick? Add more hot pasta water, 1–2 tbsp at a time.
- Too thin? Simmer 1–2 minutes; more Parmesan helps it thicken.
- Squash underdone? Roast 5 minutes longer; cubes should pierce easily with a fork.
FAQs
Q1: Can I skip roasting and simmer the squash in the skillet?
A1: Yes. Dice smaller (½-inch/1.25 cm) and simmer in broth 8–10 minutes until tender, then proceed.
Q2: What sausage works best?
A2: Mild or spicy chicken Italian sausage. Turkey sausage also works; avoid pork if you don’t eat it.
Q3: How do I make this fully dairy-free?
A3: Use oat milk, dairy-free Parmesan, and olive oil only. Emulsify with extra pasta water for creaminess.
