Try this simple and savory no-cheese dish when you’re in the mood for a heap of comfort food. What seems like a pile in each gratin dish will cook down nicely.

We’ve used store-bought kale chips here; if you make your own, toss them with nutritional yeast before they hit the oven to lend this dish maximum flavor.

Serve with a salad of peppery greens.

Make Ahead: The gratins, without the kale topping, can be cooked, cooled, covered and refrigerated up to 2 days in advance. Reheat, covered, in a 350-degree oven until warmed through.


When you scale a recipe, keep in mind that cooking times and temperatures, pan sizes and seasonings may be affected, so adjust accordingly. Also, amounts listed in the directions will not reflect the changes made to ingredient amounts.

Preheat the oven to 375 degrees. Place two individual gratin dishes on a baking sheet.

Peel and trim the sweet potato and parsnips, then cut them into matchsticks (different lengths are okay, as is heaping them together). Drizzle with the oil and toss to coat on the cutting board, then divide evenly between the gratin dishes. Season them using half of the chili powder and a good pinch of salt. Roast for about 30 minutes, stirring once, until the vegetables have cooked down a bit and are beginning to brown. Remove from the oven; keep the oven on.

Whisk together the coconut milk, the remaining chili powder and the lime juice in a liquid measuring up, then pour over each gratin dish. Stir in the fried shallots/onions, then scatter the black beans on top. Return to the oven; roast for 15 to 20 minutes or until the beans have warmed through and the gratins are bubbling.

Sprinkle the kale chips on top, then give each gratin a quick stir; serve hot.
