Say hello to the dish that’s about to steal the show at your Thanksgiving table! This Trio Sweet Potato Miso Gratin is everything you love about sweet potatoes — cozy, caramelized, naturally sweet — but with a lighter, umami-packed twist that keeps things wholesome and totally guilt-free. The creamy maple–miso marinade hugs every slice, creating layers of tender, golden perfection. Trust me… you’ll be making this long after the holidays. 🧡
Chefadora AI has the answer - timers, swaps, step-by-step help.
Wash, peel (if you prefer), and thinly slice all your sweet potatoes. Grease the bottom and sides of a casserole dish.
In a separate bowl, whisk together the white miso, maple syrup, thyme, and chicken bone broth until silky and slightly sweet.
In a baking dish, arrange the potato slices in alternating colors — orange, purple, white — for a beautiful Thanksgiving ombré effect. Pour the miso-maple broth evenly over the top, letting it settle between all the layers.
Cover the dish tightly with foil and bake at 400°F (205°C) for 20 minutes to soften the potatoes and allow them to soak up the flavor.
Remove the foil and continue baking until the top is golden, the edges caramelize, and most of the liquid has evaporated. The potatoes should be tender and slightly sticky with glaze.
Let the gratin cool for a few minutes before serving so the layers settle beautifully. Then dig in and enjoy your new go-to Thanksgiving side!
For extra caramelization, broil the gratin for 2–3 minutes after baking uncovered.
Use a mandoline slicer for evenly thin potato slices.
You can substitute chicken bone broth with vegetable broth for a vegetarian version.
Can I use regular sweet potatoes instead of the trio?
Yes, you can use any type of sweet potato you prefer. The trio adds visual appeal and flavor variety, but it's not mandatory.
Can I make this dish ahead of time?
Yes, you can prepare and bake the gratin ahead of time. Reheat it in the oven at 350°F (175°C) until warmed through before serving.
What can I use instead of white miso?
You can substitute white miso with yellow or red miso, but note that the flavor will be slightly stronger.
How do I store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
Can I make this dish vegan?
Yes, simply replace the chicken bone broth with vegetable broth and ensure your miso is vegan-friendly.
