Simple Ingredients

A complete list of ingredients is in the recipe card below.

• 3 lbs whole sweet potato, 1/4 inch thick slices: I don’t use a mandoline for these, but try to slice them as evenly as possible for perfect roasting.
• Olive oil: Use high-quality olive oil to enhance the flavor and get that delicious golden texture. Avocado oil is a great substitution.
• Spices: A flavorful mix of chili powder, smoked paprika, garlic powder, and black pepper adds the perfect kick.
• Maple syrup: Don’t skip the maple syrup drizzle—it ties all the flavors together with just the right amount of sweetness!

How to make baked sweet potatoes

Step 1: Preheat the oven:

Preheat your oven to 400°F. Line a sheet pan with parchment paper or lightly grease it with olive oil for easy cleanup.

Step 2: Prep the sweet potatoes:

Wash and peel the sweet potatoes, then slice them into 1/4-inch thick rounds. Place the slices in a large bowl.

Step 3: Toss with olive oil

Drizzle the olive oil over the sweet potato slices and toss to coat them evenly.

Step 4: Mix the seasoning

Combine the chili powder, smoked paprika, garlic powder, black pepper, and salt in a small bowl. Stir to blend the spices. Sprinkle the seasoning mixture over the sweet potato slices. Toss or use your hands to ensure the slices are evenly coated with the spices.

Step 5: Bake

Arrange the sweet potato slices in a single layer on the prepared sheet pan. Bake in the preheated oven for 15-20 minutes, flipping the slices halfway through, until they are golden brown and tender.

Step 6: Drizzle with maple syrup and serve

Once the sweet potatoes are out of the oven, drizzle the maple syrup over the top for a touch of sweetness before serving.

Storage

Store sweet potato leftovers in an airtight container for up to 4 days in the refrigerator. Be sure they have come to room temperature before storing. Reheat in the microwave in 30-second increments until warmed through.

Tips for Baked Sweet Potato Slices

• Use a sharp knife to cut the sweet potatoes.
