How to Make sweet potato and kale gratin
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat Your Oven
Preheat your oven to 375°F (190°C). While it’s heating, grab your trusty baking dish—preferably one that has seen many comfort food adventures.
Step 2: Slice Those Sweet Potatoes
Peel and thinly slice your sweet potatoes into rounds about 1/4 inch thick. The thinner they are, the more evenly they’ll cook (and let’s be honest, no one likes crunchy sweet potatoes).
Step 3: Prepare Your Kale
Wash your kale thoroughly. Remove thick stems by tearing it into bite-sized pieces that will blend nicely with the sweet potatoes.
Step 4: Sauté Garlic and Kale
In a skillet over medium heat, add a splash of olive oil. Toss in minced garlic until fragrant—about one minute—and then add your kale. Sauté until wilted (about three minutes) then remove from heat.
Step 5: Layer It Up
In your baking dish, create layers starting with half of your sweet potato slices at the bottom. Sprinkle some salt and pepper, then pile on half of your sautéed kale mixture followed by half of your heavy cream, then half of your cheddar cheese.
Step 6: Repeat Layers
Repeat step five with remaining ingredients—sweet potatoes, salt, pepper, kale, cream, and top it all off with another generous layer of cheese.
Finally, cover your baking dish with foil (to avoid any cheesy disasters) and bake for about 40 minutes. Afterward, remove the foil and let those cheesy toppings brown under broil for an additional five minutes or until golden brown.
Transfer to plates when you’re ready to serve this comforting masterpiece! Drizzle some extra cream on top if you’re feeling fancy—it’s not just any gratin; it’s *your* gratin!
