Ingredients

Instructions

  1. Cook pasta al-dente via package instructions.

  2. While the pasta boils, microwave your sweet potato for until fluffy and soft, approx. 7-8 minutes.

  3. For a super smooth sauce, break out your food processor or blender. Add your sweet potato along with 1/4 cup whole milk (from your 1 cup) until smooth.

  4. Heat butter and garlic in the microwave for 20 seconds to infuse the flavor, add to your puree and pulse.

  5. Drain pasta and return to pot, switching burner to medium heat.

  6. Immediately add the remaining 3/4 cup of milk along with salt and garlic powder to the pasta and stir constantly.

  7. Add sweet potato puree and parmesan cheese and continue stirring constantly until the sauce starts to thicken. This usually takes 5-10 minutes.

  8. The end result is a sauce that's super thick, creamy, and full of flavor!

Chef's Notes

If you feel like you’d like the sauce a little thinner, snag a little extra milk to add to the sauce. Start with a TBSP and work your way up. You can also thin it with a little melted butter if desired, delicious!
For a feisty burst of flavor, snag some cajun seasoning to add to your sauce! Add anywhere between 1/2 and 1 + 1/2 tsp of cajun seasoning blend. We make this sauce cajun style when adding roasted chicken or sautéed shrimp to the pasta. It’s SO GOOD!
Just before serving, I crumbled a little goat cheese on top of my pasta out of sheer curiosity. I LOVED it! Feel free to follow suit. I served my pasta on a bed of fresh arugula. Wilted spinach would make a great addition to round out the meal if you’re feeling a bit more conventional, lol! Either way, I hope you love this pasta as much as we do!

This recipe was incredible!!!! My toddler loved it too. I want to make it for a friend but she cannot have dairy. Is there a way to make this dairy free? 😬

Loved the sweet potato alfredo, I omitted the lemon juice but added some nutmeg, was yummy.

Ashley Lamb ★ 5.0/5

I added extra garlic and played around with a few dashes of whatever seasonings were in reach. I also added sundried tomatoes as a topping and that was the perfect touch for me! Will definitely be making again.
