Step-by-Step Instructions

Prepare the Sweet Potato Noodles: If you’re using fresh sweet potatoes, spiralize them into noodles using a spiralizer. If you prefer to save time, you can also buy pre-spiralized sweet potato noodles from the store. Heat a large pan over medium heat and add the olive oil. Once heated, add the sweet potato noodles and sauté for about 5-7 minutes, or until they are tender and slightly caramelized. Be careful not to overcook them, as you want the noodles to retain some texture.
Make the Alfredo Sauce: While the noodles are cooking, place the soaked cashews, almond milk, nutritional yeast, garlic, lemon juice, thyme, salt, and pepper into a blender or food processor. Blend until smooth and creamy. If the sauce is too thick, add a little more almond milk to reach your desired consistency.
Combine the Noodles and Sauce: Once the sweet potato noodles are cooked, pour the creamy Alfredo sauce over the noodles in the pan. Toss the noodles and sauce together until the noodles are fully coated and the sauce is heated through. If you’re adding spinach or kale, toss it in at this stage and cook for an additional 2-3 minutes until wilted.
Taste and Adjust: Taste the dish and adjust the seasoning if necessary. You can add more salt, pepper, or lemon juice to balance the flavors.
Serve and Garnish: Serve the Sweet Potato Noodle Alfredo in bowls and garnish with fresh parsley for a pop of color and freshness. You can also sprinkle a bit more nutritional yeast or your favorite dairy-free cheese on top if desired.

Variations

Add Protein: For a heartier dish, top your Sweet Potato Noodle Alfredo with grilled chicken, shrimp, or crispy tofu.
Veggie Boost: Toss in some sautéed vegetables like mushrooms, zucchini, or broccoli for extra flavor and nutrients.
Spicy Version: If you like a bit of heat, add a pinch of cayenne pepper or red pepper flakes to the sauce for a spicy kick.
Vegan Parmesan: If you want to keep this dish vegan, opt for a sprinkle of vegan Parmesan cheese in place of regular cheese.

Frequently Asked Questions (FAQs)
