Why You’ll Love This Recipe

Quick, Easy, and Holiday-Friendly

• Ready in 30 minutes
• Perfect side dish for Thanksgiving or any fall dinner
• Uses just a handful of pantry staples

Flavorful and Satisfying

The dish is rich and creamy from the Parmesan and Pecorino cheeses, with a generous amount of cracked black pepper that adds warmth and spice. The sweet potato noodles bring a slightly sweet, earthy balance and a tender-but-toothsome texture.

Naturally Gluten-Free

This recipe is completely gluten-free as long as your cheese is certified GF. It's also vegetarian and can easily be made dairy-free with the right swaps.

Ingredients and Substitutions

What You’ll Need

• 2 tablespoons extra-virgin olive oil, divided
• 12 ounces spiralized sweet potatoes, cut into 10- to 12-inch lengths
• 1 ½ teaspoons kosher salt (plus more to taste)
• 1 tablespoon unsalted butter
• 1 teaspoon freshly ground black pepper (plus more for topping)
• ½ cup finely shredded Parmesan cheese
• ½ cup finely shredded Pecorino Romano cheese

Ingredient Tips

• Fresh sweet potato noodles are best. Avoid frozen ones, which can turn mushy when cooked.
• Use real, aged cheeses for the best flavor and melting quality.
• Use a nonstick skillet to prevent the noodles from sticking and breaking apart.

Easy Swaps

• Use all Parmesan if Pecorino isn’t available.
• Try vegan butter and dairy-free cheeses to make it plant-based.
• Substitute spiralized butternut squash or zucchini if you’re out of sweet potatoes.

How to Make Cacio e Pepe Sweet Potato Noodles

Step 1: Get Everything Prepped

Shred the cheeses, spiralize the sweet potatoes (or use pre-spiralized), and have all ingredients within reach. This recipe comes together quickly, so prep is key.

Step 2: Cook the Noodles

Heat 1 tablespoon of olive oil in a medium nonstick skillet over medium-high heat. Add the sweet potato noodles and salt. Cook for 2 to 3 minutes, tossing gently until the noodles are slightly softened but still have a bit of crunch.

Step 3: Make the Sauce

In a separate large skillet, melt the butter with the remaining olive oil over medium-low heat. Add the black pepper and swirl for about 30 seconds, just until fragrant.

Step 4: Combine

Transfer the sweet potato noodles into the buttery pepper mixture. Add the Parmesan and Pecorino cheeses. Toss gently to coat everything evenly. The cheese should melt into a glossy, rich sauce that clings to every noodle.

Step 5: Serve

Divide the noodles between bowls. Top with extra Parmesan and a little more black pepper for that final touch.

Expert Tips for Success

Don’t Overcook the Noodles

Sweet potato noodles cook much faster than pasta. Remove them from heat while they’re still slightly firm—they’ll continue softening in the sauce.

Use Freshly Cracked Pepper

The bold flavor of Cacio e Pepe relies on good quality black pepper. Coarsely grind it for maximum aroma and taste.

Use a Nonstick Skillet

Sweet potato noodles are more delicate than pasta and can stick easily. Nonstick pans help maintain the noodle texture.

What to Serve with Cacio e Pepe Sweet Potato Noodles

Ideal Pairings

• Roast turkey or herbed chicken
• Garlic green beans or roasted Brussels sprouts
• Crispy tofu or sautéed mushrooms for a vegetarian option

Holiday Presentation Ideas

Serve in a shallow serving bowl topped with a dusting of Parmesan and a few twists of black pepper. Garnish with fresh herbs like thyme or parsley for a pop of green.

Best Drinks to Serve

• A dry white wine like Pinot Grigio
• Sparkling water with a citrus twist
• Light-bodied red wine such as Pinot Noir

Storing and Reheating Leftovers

How to Store

Refrigerate leftovers in an airtight container for up to 3 days. This dish is not ideal for freezing, as the sweet potatoes may become soggy.

Reheating Tips

Reheat gently in a nonstick pan over low heat with a splash of water or oil to loosen the sauce. Avoid microwaving for too long, which can make the noodles too soft.
