Ingredient & Substitution Notes

This section explains how to choose the best ingredients for this easy mashed sweet potatoes recipe, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

Sweet Potatoes – I prefer to peel them (for silky smooth mashed sweet potatoes), but you can leave the skin on if you prefer. You can also substitute yams, which are similar to sweet potatoes, but less sweet.Unsalted Butter – The most classic choice for this recipe, but you can also use ghee, butter flavored coconut oil for a vegan alternative, or even bacon grease.Garlic – With so few ingredients, fresh minced garlic tastes the best. However, you can also use jarred minced garlic. Alternatively, you can substitute 1/4 to 1/2 teaspoon garlic powder and add it at the end.Milk – Makes the sweet potato mash more creamy. You can use dairy milk, heavy cream for an ultra-rich dish, coconut milk or almond milk for dairy-free alternatives, or omit completely for a firmer texture.Sea Salt & Black Pepper – For easy seasoning.

Recipe Variations

Extra Sweetness – You can easily sweeten these potatoes more with a sprinkle of brown sugar (or brown sugar substitute), or a drizzle of maple syrup.Fall Spices – Mix in a pinch of cinnamon or pumpkin pie spice for an instant cozy taste.Fresh Herbs – Try fresh thyme or fresh rosemary with a sprinkle of parmesan cheese to create rich and savory flavor.Bacon – Cook bacon using your favorite method (I prefer bacon in the oven or air fryer bacon, but microwave bacon works in a pinch). Then, crumble it and stir into the mash at the end, or just use it for topping.Healthy Mashed Sweet Potatoes – As a whole food dish with simple ingredients, I already consider this fairly healthy, but if you like, replace the butter with olive oil instead.
