Ingredient Notes
Here’s a quick overview of the key ingredients for this recipe. For the full list of ingredients and exact measurements, be sure to check the recipe card at the bottom of this post.
- Sweet potatoes: Choose firm, medium sweet potatoes with bright orange flesh. You can also use these in my Southern Recipe For Sweet Potato Cornbread, Crispy Roasted Sweet Potatoes in the Oven, and How to Air Fry Sweet Potatoes Wedges for Perfect Crispy Fries.
- Onion: Pick a small yellow onion with tight, papery skin and finely dice it.
- Garlic: Use fresh garlic cloves, peel and crush or mince them.
- Tofu: Pick silken or soft tofu from the refrigerated case or shelf-stable box, then drain.
- Milk: Use whole milk for the richest flavor, or your favorite unsweetened dairy-free milk if you prefer a lighter or dairy-free sauce.
- Nutritional yeast: Choose a good-quality nutritional yeast with a nutty, Parmesan-style flavor.
- Turmeric: Reach for ground turmeric with a bright color.
- Pasta: Fusilli is ideal, so all the little spirals can hold on to the thick, creamy sweet potato pasta sauce.
- Bell pepper: Look for a firm red pepper with glossy skin that feels heavy for its size. Remove the seeds and dice it into small pieces.
- Mushrooms: Use fresh button or cremini mushrooms and dice or slice them.
- Spinach: Grab fresh baby spinach with dark green leaves that you can stir straight into the pan until it just wilts.
- Parmesan cheese: Use freshly grated parmesan from a wedge or a good-quality pre-grated cheese to sprinkle over the hot pasta, or swap for a vegan parmesan if needed.
How To Make Sweet Potato Pasta Sauce
Cook Sweet Potatoes and Aromatics
Pierce the sweet potatoes and microwave until very soft, then let them cool slightly and scoop out the flesh. In a pan, sauté the diced onion in a little oil until softened, then add the crushed garlic and cook for about a minute until fragrant.
Blend
Add the sweet potato flesh, cooked onion and garlic, silken tofu, turmeric, milk, nutritional yeast, salt, and pepper to a food processor. Blend until the sauce is completely smooth and creamy, then set it aside.
Cook Pasta and Vegetables
Boil the pasta in a large pot of salted water according to the package, then reserve some pasta water before draining. In a wide skillet, sauté the diced red bell pepper and mushrooms in a little olive oil until softened, then add the crushed garlic for a minute and stir in the spinach until it wilts.
Combine
Add the cooked pasta, reserved pasta water, and sweet potato sauce to the pan with the vegetables. Stir over low heat until everything is heated through and the pasta is evenly coated, then taste and adjust the salt and pepper.
Serve
Serve the pasta hot in bowls or on a platter. Top with grated parmesan or your favorite vegan alternative just before serving.
You can blend the sauce earlier in the day or the night before, refrigerate it, and reheat it gently in a pan while the pasta cooks, adding a little pasta water if it has thickened.
Yes, this sauce works with almost any pasta shape; just choose a shape with grooves or ridges so the creamy sweet potato pasta sauce clings well.
Variations, Substitutions, and Recipe Tips
Dietary Modifications: Use unsweetened plant-based milk and vegan parmesan to keep the pasta fully vegan, and choose gluten-free pasta if someone at your table avoids wheat, so everyone can still enjoy this healthy sweet potato pasta sauce together.
Flavor Enhancements: Add Italian herbs, extra garlic, or a pinch of smoked paprika to the sauce if you want a stronger flavor. A small splash of lemon juice or extra nutritional yeast at the end can brighten and deepen the taste. If you want a fresh, herby finish, a spoonful of 5-Minute Fresh Basil Pesto Sauce on top is such a simple way to make it feel special.
Add-In Options: Stir in extra vegetables like zucchini, kale, peas, or roasted broccoli along with the spinach. You can top each bowl with grilled chicken, turkey sausage, or crispy chickpeas, and finish with toasted nuts or seeds for a little crunch.
Simple Substitutions: If you do not have silken tofu, use plain Greek yogurt for a similar creamy texture. You can also swap in any sweet bell pepper color.
Tips for Recipe Success: Taste the sauce in the blender so you can adjust the salt, pepper, and savory notes before adding it to the pan. Save some pasta water and use it to thin the sauce to a silky consistency. Avoid overcooking the pasta.
