How to Make Crispy Roasted Sweet Potatoes with Miso Maple Glaze

For the complete recipe and measurements, scroll to the recipe card at the bottom of this post.

Step 1: Fill a large pot with 2-3 quarts of water and add 2 teaspoons of salt. Place it on the stove and let it come to a boil over high heat.

Step 2: Carefully add the potatoes to the boiling water and boil for around 14 minutes. Check with a fork to make sure they're firm but still tender enough to be pierced. Once they're done, drain them well.

Step 3: Working in small batches, gently toss the sweet potatoes in the olive oil.

Step 4: Transfer the sweet potatoes to the prepared baking sheet, making sure to spread them out with at least 1 inch of space between each piece. Sprinkle them lightly with salt.

Step 7:  In a small mixing bowl, combine the miso, maple syrup, balsamic vinegar, and toasted sesame oil until combined. Spoon the miso glaze over the potatoes.

Recipe Pro-Tips

  • Testing for doneness: To check if the sweet potatoes are fully cooked, just grab a fork and give them a gentle poke. They should be tender and easily pierced without any resistance
  • Spread 'em out: Once on the baking sheet, make sure to give those sweet potato slices some room to breathe. Spreading them out at least an inch apart ensures they'll brown evenly and get that perfect crispiness we all crave.
  •  Monitoring baking time: Ovens can be a bit temperamental, so keep a close watch on the sweet potatoes in those final minutes of baking. We want them to be golden brown and tender, but not overly crispy. Adjust the baking time as needed to achieve perfection.

Recipe Variations

  • Herb-infused: Elevate the flavor profile by incorporating your favorite herbs and spices. Try tossing the sweet potato slices with a combination of rosemary, thyme, and garlic powder before roasting. The aromatic blend will infuse the potatoes with a fragrant and savory note.
  • Spicy kick: If you're a fan of heat, spice things up by adding a pinch of cayenne pepper or red pepper flakes to the olive oil coating before baking. The subtle heat will complement the sweetness of the potatoes and add a tantalizing kick to each bite.
  • Extra crispy: Looking for an even crispier texture? Increase the oven temperature to 475 degrees Fahrenheit and extend the baking time by a few minutes, while keeping an eye on them. This will give you beautifully caramelized edges and an irresistible crunch.

Crispy roasted sweet potatoes are as delicious served as a weeknight side dish as they are perfect served as part of a dinner party or holiday meal. They go great with roast pork tenderloin, grilled chicken, hamburgers, air fryer salmon, or any time you are looking for a flavorful and easy sweet potato side dish!

Though I love serving these potatoes as-is, you can also garnish them with fresh cilantro or parsley, always serving hot for the best flavor!

Storage Directions

  • Refrigeration: Leftovers keep covered in an airtight container in the refrigerator for 3-4 days. 
  • Freezing: Leftover sweet potatoes can also be frozen in a freezer-safe container for up to 3 months. 
  • Heating: Reheat leftovers gently in the microwave until they are heated through, taking care not to overheat them and make them dry. However, the texture of the roasted sweet potatoes may change slightly after refrigeration, becoming slightly softer.

FAQs

Can I adjust the sweetness of the miso maple glaze?

Of course! You have complete control over the sweetness of the glaze, allowing you to customize it to your liking. If you have a sweet tooth, you can add a bit more maple syrup to enhance the sweetness. If you prefer a more balanced or savory flavor profile, you can reduce the amount of maple syrup and play around with the miso or balsamic vinegar for a tangier kick.

Can I substitute the white miso with another type of miso?

Yes! While white miso is recommended for its gentle and subtly sweet flavor, you can certainly experiment with different types of miso if you don't have white miso available. Yellow or red miso can be great alternatives, although the flavor may vary slightly, so you may need to adjust the quantity based on your personal preference.

Can I use other types of potatoes instead of sweet potatoes?

While sweet potatoes are the star ingredient of this recipe, you can experiment with other types of potatoes if you prefer. Purple sweet potatoes or yams would be my top recommendations. However, keep in mind that the texture and flavor may vary. Classic sweet potatoes provide a unique sweetness and tenderness that complement the miso maple glaze perfectly.
