Instructions

Roast the Sweet Potatoes

Preheat the oven to 425°F (220°C).

Line a baking sheet with parchment paper.

Toss sweet potato cubes with olive oil, salt, and black pepper.

Spread them evenly on the tray in a single layer.

Roast for 25–30 minutes, flipping halfway through, until golden, tender, and lightly caramelized.

Cook the Pasta

Bring a large pot of salted water to a boil.

Cook penne according to package instructions until al dente.

Reserve 1/2 cup of pasta water, then drain and set aside.

Make the Creamy Goat Cheese Sauce

In a large skillet, melt butter over medium heat.

Add garlic and chopped sage, cooking for 1–2 minutes until fragrant.

Pour in the cream and bring to a gentle simmer.

Lower the heat and whisk in goat cheese until smooth and creamy.

Season with salt and black pepper.

If the sauce feels too thick, add a splash of reserved pasta water.

Combine Everything

Add the cooked penne to the sauce and toss until fully coated.

Gently fold in roasted sweet potatoes.

Stir carefully so the sweet potatoes hold their shape.

Serve

Plate the pasta and top with extra goat cheese.

Garnish with crispy sage leaves, black pepper, and toasted walnuts if using.

Serve warm.

Tips for Success

Roast Sweet Potatoes Properly

Make sure they are spread in a single layer so they caramelize instead of steaming.

Don’t Overcook Pasta

Al dente pasta holds up better in creamy sauces and prevents mushiness.

Use Room Temperature Goat Cheese

It melts more smoothly into the sauce and avoids clumping.

Save Pasta Water

The starch helps emulsify the sauce and gives it a silky restaurant-style texture.

Control the Heat

Keep the sauce on low heat once cream is added to avoid curdling.

Balance the Flavors

Goat cheese is tangy, so taste before adding extra salt.

Crisp the Sage

Frying whole sage leaves in a bit of butter makes them aromatic and crunchy for garnish.

Add Sweet Potatoes Last

Fold them in gently to avoid breaking them apart.

Finish with Fresh Black Pepper

It enhances both the sweetness and creaminess of the dish.

Serve Immediately

The sauce is at its best when freshly combined and warm.

Variations

Chicken Version

Add grilled or roasted chicken breast for extra protein.

Bacon & Sage Twist

Crisp bacon and mix it into the pasta for a smoky flavor.

Vegetarian Protein Boost

Add chickpeas or white beans for added texture.

Spinach Addition

Stir in fresh spinach at the end for extra greens.

Butternut Squash Swap

Replace sweet potatoes with roasted butternut squash for a similar flavor profile.

Parmesan Cream Version

Swap half the goat cheese with Parmesan for a milder sauce.

Spicy Kick

Add chili flakes or a pinch of cayenne to the sauce.

Nut-Free Version

Skip walnuts or replace with pumpkin seeds for crunch.

Frequently Asked Questions

Can I use another pasta shape?

Yes. Rigatoni, fusilli, or farfalle all work well.

Can I make this ahead of time?

You can roast the sweet potatoes ahead, but assemble the pasta fresh for best texture.

Can I use milk instead of cream?

Yes, but the sauce will be slightly lighter and less rich.

Why is my sauce grainy?

The heat may be too high or the goat cheese was added too quickly. Lower the heat and whisk gradually.

Can I reheat leftovers?

Yes. Reheat gently on the stove with a splash of milk or cream to loosen the sauce.

Can I freeze this dish?

It’s not ideal. Cream-based sauces can separate after freezing.

What herbs can replace sage?

Thyme or rosemary are good alternatives.

How do I make it vegan?

Use plant-based cream, vegan butter, and dairy-free cheese alternatives.
