How to Make Baked Miso Sweet Potato Slices

  1. Preheat the Oven: Set your oven to 350 °F (180 °C) and grease your casserole dish with a splash of olive oil to prevent sticking.

  2. Prepare the Miso Sauce: In a small saucepan, combine the melted butter, maple syrup, and white miso. Heat over medium, stirring until everything is fully melted and mixed. Take it off the heat and whisk in the rice vinegar, minced ginger, and garlic.

  3. Toss the Sweet Potatoes: In a large bowl, place your finely sliced sweet potatoes. Pour in the miso sauce and gently toss until every slice is evenly coated, ensuring that lovely sauce clings to them.

  4. Arrange in Dish: Layer the sweet potatoes in your prepared casserole dish or cast iron skillet in a circular pattern, slightly overlapping them. Don t forget to save any extra sauce that may fall to the bowl’s bottom!

  5. Cover and Bake: Cover your dish with foil and pop it in the oven. Bake for 35 minutes, or until the sweet potatoes become tender.

  6. Increase Heat: Once soft, remove the dish from the oven and raise the temperature to 400 °F (204 °C). Brush the tops of the sweet potatoes with the reserved miso sauce for extra flavor.

  7. Final Bake: Bake uncovered for an additional 25 minutes until the edges are beautifully browned and crispy. You can check their doneness by piercing them with a fork. For that perfect crisp, broil for the last 2 minutes.

  8. Garnish and Serve: Once baked, generously garnish with diced green onions and a sprinkle of flaky sea salt. Serve hot and enjoy the flavors!

Optional: Drizzle with an extra bit of maple syrup for added sweetness!

How should I store leftovers?
After enjoying your Baked Miso Sweet Potato Slices, store any leftovers in an airtight container in the refrigerator for up to 3 days. I recommend reheating them in the oven at 350 °F (180 °C) for about 10-15 minutes to maintain that satisfying crispiness.

Can I freeze baked sweet potato slices?
Very! To freeze, arrange the cooled slices in a single layer on a baking sheet and place them in the freezer for about 1-2 hours until firm. Then, transfer them to an airtight container or freezer bag labeled with the date. They will stay fresh for up to 2 months. When you re ready to enjoy, bake straight from the freezer at 375 °F (190 °C) for about 15-20 minutes until warmed through.

What if my sweet potatoes are not cooking evenly?
If you find that your sweet potato slices are unevenly cooked, it might be due to inconsistent slicing. For best results, make sure to slice the sweet potatoes uniformly, about ¼ inch thick. If some slices still seem undercooked after the initial bake, you can cover them again with foil and return them to the oven for an additional 10-15 minutes.

Are Baked Miso Sweet Potato Slices pet-friendly?
No, it s best to avoid giving your pets these slices, mainly due to the inclusion of garlic and miso, which are not suitable for animals. However, the sweet potatoes themselves are safe for dogs in moderation if you wish to share!

Can I adjust the recipe to be vegan?
Absolutely! For a vegan twist, simply replace the unsalted butter with a plant-based butter or coconut oil, and ensure your maple syrup is pure (as it typically is). This way, you can enjoy the delightful flavors of Baked Miso Sweet Potato Slices while keeping it plant-based!
