Preheat your oven to 400 degrees f. and lightly grease a round 2-quart baking dish with a touch of oil.

Scrub your sweet potatoes and remove any dark spots with a knife.

Rinse your sweet potatoes thoroughly to remove any dirt and pat the excess moisture with a towel.

Using a mandoline or a very sharp knife, carefully slice your potatoes into 1/8-inch thick rounds.

In a mixing bowl, whisk your 1/4 cup oil of your choice, maple syrup or honey, fresh squeezed lime juice, garlic, paprika, cumin, oregano, red chili flakes, and sea salt.

Add potato rounds and gently toss until they are well coated in this dressing. Sprinkle with parmesan.

Layer your potato rounds nicely in your prepared baking dish as shown in the photos.

Using a rubber spatula, pour the remaining dressing from the bowl over the top of your sweet potatoes in the baking dish.

Cover your dish, and bake for 40-45 minutes until sweet potatoes are tender.

Uncover your dish, sprinkle lightly with a bit more parmesan if desired, and continue to bake for 10 minutes more, or until the tops are beautiful golden brown.

Garnish with fresh chopped cilantro or parsley, fresh cracked black pepper, and lime wedges.

Serve warm or at room temperature.
