Ingredients and substitutions
Sweet potatoes add nutrients, a satisfying texture, and delicious flavor to this sauce.
Fresh sage adds a warm, woodsy flavor that pairs perfectly with sweet potatoes. You can substitute dried sage if you prefer (alternatively dried thyme or rosemary would be delicious too).
Fresh garlic adds a savory layer of flavor to this sweet potato pasta sauce. You can substitute one teaspoon of jarred chopped garlic or garlic powder if you prefer.
I used unsweetened oat milk in this sauce but you can use any type of milk you prefer.
How to make it
Start by preheating the oven to 400 degrees Fahrenheit. Add the peeled, chopped sweet potatoes, extra virgin olive oil, peeled garlic cloves (leave them whole), and chopped sage to a baking dish. Mix well to coat the sweet potatoes in oil.

Bake at 400 degrees Fahrenheit for 45 minutes or until the sweet potatoes are fork tender.

Add the cooked sweet potatoes, cooked garlic cloves, unsweetened plant-based milk, salt, and pepper to a blender or food processor.

Blend until smooth.

Heat the sauce to your desired temperature, then toss with your favorite pasta.
Optional garnishes
Garnish with fresh sage leaves, finely chopped chives, or a sprinkle of these spiced sunflower seeds, if desired.
Storage and freezing
