To find your microwave’s wattage, look at the front panel, the side of the door, in the back, in the user manual, or Google the model number. If both an input and output wattage are listed, use the output.

Wattage translates to how powerful the microwave is. The higher the wattage, the faster your food will cook. The lower the wattage, the longer the cook time.

When in doubt, start with less time — you can always add more.

Dish

The Medium Deep Dish

Ingredients

  • 1 (340g) medium sweet potatoes, skin on
  • 2 tablespoons unsalted butter, room temperature
  • 1 teaspoon miso paste
  • 2 teaspoons tahini
  • sesame seeds, optional

Preparation

  1. Prick sweet potatoes all over with a fork, and place them in an Anyday dish. If too thick, cut it in half lengthwise (like a baked potato). Cover with the lid (knob lifted).
  2. Cook in the microwave for 7-8 minutes, until the sweet potatoes are tender when pierced with a fork.
  3. In a separate bowl, mix the butter, miso, and tahini until well incorporated. It’s easiest to do this when the butter is very soft at room temperature!
  4. Remove the sweet potatoes, cut partially in half lengthwise, and add a spoonful of miso tahini butter in the center. Garnish with sesame seeds and serve.

Suggestions

  • Try Japanese yams: Use yellow Japanese yams for a fluffier texture and naturally candy-sweet flavor.
  • Swap the tahini: Substitute tahini with cashew butter for a milder, slightly sweet alternative.
  • Add bold toppings: Sprinkle with chili crisp, sliced scallions, or fresh herbs for extra texture and flavor.
  • Mix in warming spices: Sprinkle with cinnamon, smoked paprika, or cumin for a spiced twist that complements the natural sweetness of the potatoes.

Recipe Notes

  • Save time: make the miso and tahini butter ahead of time and even freeze in the 2 Tbsp Anytime Freezer Trays and use when needed.
  • Microwave ovens vary, even with the same wattages. Adjust cooking times as needed.

All You Need to Know About Making Sweet Potatoes with Miso Butter in the Microwave

Can I cook sweet potatoes in the microwave?

Yes! The microwave is one of the fastest ways to cook sweet potatoes. Use an Anyday dish to evenly steam the sweet potatoes while locking in moisture. Simply prick the potatoes, cover with the lid (knob lifted), and cook until fork-tender.

How do I know when sweet potatoes are cooked?

Sweet potatoes are fully cooked when they feel tender when pierced with a fork. If they are still firm in the center, continue microwaving in 1-2 minute increments until soft.

Can I make this recipe dairy-free?

Yes, you can make this recipe dairy-free! Replace the butter with a plant-based butter, olive oil, or peanut butter.

How long can I store leftover sweet potatoes?

Once cooled, store any leftover sweet potatoes in an Anyday dish with the lid on in the fridge for up to 4 days. You can store extra miso tahini butter and keep it in an Anytime Freezer Tray for easy portioning.

What’s the best way to reheat sweet potatoes?

Place the sweet potatoes in an Anyday dish and cover with the lid. Microwave on full power for 1-2 minutes, or until warmed through. If microwaving the potatoes from frozen, reheat in 30-second increments.

Can I use regular potatoes instead of sweet potatoes?

Yes, you can use regular potatoes instead of sweet potatoes in this recipe! However, the natural sweetness of sweet potatoes pairs well with miso tahini butter. Adjust the cooking time as needed, as white potatoes may take longer to soften. Discover more potato recipes by exploring our collection here!

Can I customize the toppings?
