Ingredients
For this velvety penne the key is using fresh, high‑quality components that each contribute texture and flavor. The sweet, roasted butternut squash forms the heart of the sauce, while the creamy dairy base binds everything together. A blend of aromatic herbs and a sharp Parmesan finish adds depth, and the penne’s ridged shape captures every luscious bite.
Main Ingredients
- 12 oz (340 g) penne pasta
- 2 lb (900 g) butternut squash, peeled and cubed
- 1 large onion, finely diced
- 2 cloves garlic, minced
Sauce Components
- 1 cup (240 ml) low‑fat half‑and‑half
- ½ cup (50 g) freshly grated Parmesan cheese
- ¼ cup (60 ml) vegetable broth
- 2 tablespoons unsalted butter
Seasonings & Garnish
- 1 teaspoon dried sage (or 2 tsp fresh, chopped)
- ½ teaspoon nutmeg, freshly grated
- Salt and freshly cracked black pepper, to taste
- 2 tablespoons extra‑virgin olive oil
- Optional: toasted pine nuts and fresh parsley for garnish
The sweet flesh of the butternut squash provides a natural caramel base, while the butter and olive oil create a glossy finish. Half‑and‑half adds body without overwhelming richness, and the Parmesan delivers that unmistakable umami punch. Sage and nutmeg bring autumnal warmth, and a pinch of salt amplifies every flavor, ensuring each bite is perfectly balanced.
Step-by-Step Instructions
Preparing the Squash
Preheat your oven to 400°F (200°C). Toss the cubed butternut squash with 1 tablespoon olive oil, a pinch of salt, and half the sage. Spread it in a single layer on a baking sheet and roast for 20‑25 minutes, turning once, until the edges are caramelized and the interior is fork‑tender. Roasting concentrates the natural sugars, giving the sauce its signature depth.
Cooking the Pasta
While the squash roasts, bring a large pot of salted water to a rolling boil. Add the penne and cook according to package instructions until al dente, usually 10‑11 minutes. Reserve ½ cup of the pasta cooking water, then drain the pasta and set aside. The starchy water will help emulsify the sauce later.
Making the Sauce
- Sauté the aromatics. In a large skillet over medium heat, melt the butter with the remaining 1 tablespoon olive oil. Add the diced onion and cook, stirring occasionally, for 4‑5 minutes until translucent. Add the minced garlic and the remaining sage; sauté for another 30 seconds until fragrant, being careful not to let the garlic brown.
- Blend the roasted squash. Transfer the roasted squash to a food processor, add the vegetable broth, and blend until completely smooth. If the puree is too thick, add a splash of the reserved pasta water to achieve a silky consistency.
- Combine cream and cheese. Return the squash purée to the skillet, stir in the half‑and‑half, and bring to a gentle simmer. Sprinkle in the grated Parmesan and grated nutmeg, stirring constantly until the cheese melts and the sauce thickens enough to coat the back of a spoon, about 3‑4 minutes.
- Finish the sauce. Taste and adjust seasoning with salt and pepper. If the sauce seems too thick, whisk in a little more pasta water, one tablespoon at a time, until you reach a glossy, velvety texture.
Combining & Finishing
Add the cooked penne to the skillet, tossing gently to ensure every tube is coated with the creamy squash sauce. Cook together for 2‑3 minutes over low heat, allowing the pasta to absorb the flavors. Remove from heat, sprinkle the optional toasted pine nuts and a handful of fresh parsley, then serve immediately while the sauce is still luxuriously smooth.
Tips & Tricks
Perfecting the Recipe
Roast Until Caramelized. Push the squash to the edge of the pan for extra browning; the caramelized bits add a subtle smoky sweetness that elevates the sauce.
Don’t Over‑cook the Pasta. Al dente pasta continues to absorb sauce during the final toss, preventing a mushy texture.
Flavor Enhancements
Brighten the finished dish with a squeeze of fresh lemon juice just before serving. A pinch of red‑pepper flakes adds a gentle heat that contrasts the sweet squash. For extra richness, stir in a tablespoon of mascarpone at the end of the simmer.
Common Mistakes to Avoid
Avoid adding the cream too early; it can curdle if the pan is too hot. Also, don’t skip the reserved pasta water—without it the sauce may become too thick and cling poorly to the penne.
Pro Tips
Use a Heavy‑Bottom Skillet. Even heat distribution prevents scorching of the butter and ensures a smooth sauce.
Season in Layers. Add a little salt at each stage—on the squash, in the sauce, and at the end—to build depth without over‑salting.
Finish with Fresh Herbs. Chopped sage or parsley added at the last minute preserves their bright flavor and color.
Reserve Extra Parmesan. A final sprinkle at the table adds a salty crunch and visual appeal.
Variations
Ingredient Swaps
Replace penne with rigatoni or farfalle for a different bite. Swap the butternut squash for sweet potato or pumpkin if you prefer a deeper orange hue. For a non‑dairy version, use coconut cream and nutritional yeast instead of half‑and‑half and Parmesan.
Dietary Adjustments
Choose gluten‑free pasta to keep the dish safe for gluten sensitivities. For a vegan spin, substitute butter with olive oil, use plant‑based cream, and replace Parmesan with a vegan “nut‑based” cheese. Low‑carb lovers can serve the sauce over spiralized zucchini noodles.
Serving Suggestions
Pair the penne with a simple arugula salad dressed in lemon vinaigrette, or serve alongside roasted Brussels sprouts for extra crunch. A slice of crusty sour‑dough bread is perfect for mopping up any remaining sauce, while a glass of lightly oaked Chardonnay complements the creamy texture.
Storage Info
Leftover Storage
Allow the dish to cool to room temperature, then transfer it to an airtight container. Store in the refrigerator for up to 3 days. For longer keep, portion into freezer‑safe bags, flatten, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating Instructions
Reheat gently on the stovetop over low heat, adding a splash of broth or milk to restore creaminess. Stir frequently until heated through, about 5‑7 minutes. In the oven, cover with foil and bake at 350°F (175°C) for 15 minutes. Microwaving works in a pinch—heat in 30‑second bursts, stirring between intervals.
