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 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.
