Creamy Potato Kale Gratin Recipe By Tasty

KALE AND POTATO GRATIN

Steps:

• Preheat oven to 350°. Butter a 2-quart shallow baking dish.
• Wash, derib and coarsely chop the kale.
• Place in a pot with a little bit of water and steam until almost tender, 5 minutes or so. Check to make sure it's not burning.
• Peel and cut potatoes and onions into 1/8-inch thick rounds.
• If desired, saute onions until lightly browned. It gives more flavor, I think.
• Drain kale and let stand until cool enough to handle. Press out excess water.
• Build up alternating layers of potatoes, onions and kale (two layers each) in baking dish, beginning and ending with potatoes and dotting each onion layer with butter, minced tarragon, salt, pepper and garlic powder.
• Pour half-and-half over top, cover and bake in oven until potatoes are tender and almost all liquid is absorbed, 30-45 minutes.
• Place under broiler, if desired, to brown the top.

CHEESY POTATO AND KALE GRATIN WITH RYE CROUTONS

Steps:

• Arrange a rack in center of oven; preheat to 350ºF. Arrange bread slices on a rimmed baking sheet and bake, flipping once halfway through, until dry and lightly toasted, 15-20 minutes. Let cool. Transfer to a resealable plastic bag and break into irregular, 1/2"-1" pieces. Transfer to a medium bowl; set aside.
• Meanwhile, wash and spin-dry kale, then layer between paper towels or a large clean kitchen towel and pat dry.
• Mix Gruyère and Parmesan in a medium bowl. Shingle one-quarter of potatoes in 3 or 4 rows, slightly overlapping, in bottom of baking dish. Sprinkle with one-quarter of thyme, 1/4 tsp. salt, and 1/8 tsp. pepper. Top with 2 cups kale and one-quarter of cheese mixture. Repeat 2 more times. Shingle remaining potatoes over cheese; top with 1/4 tsp. salt, 1/8 tsp. pepper, and remaining thyme. Reserve remaining kale and cheese.
• Stir cream, garlic, 1/4 tsp. salt, and 1/8 tsp. pepper in a liquid measuring cup. Pour evenly over potatoes.
• Bake gratin 40 minutes. Cover with foil and continue to bake until cream is bubbling and thick and potatoes are tender when pierced with a paring knife, 35-45 minutes more.
• Meanwhile, toss reserved croutons with 2 Tbsp. oil in a medium bowl. Toss remaining kale with remaining 1 Tbsp. oil. Top gratin with kale, remaining cheese, then croutons, allowing kale pieces to peek through. Bake gratin until croutons are golden brown and exposed kale edges are well-crisped, about 15 minutes more. Let cool at least 10 minutes before serving.
• Do Ahead
• Bread can be toasted 3 days ahead. Store in an airtight container at room temperature. Kale can be torn, washed, and patted dry 3 days ahead. Wrap in paper towels, place in a resealable plastic bag, and chill.
• Gratin can be made 1 day ahead. Let cool, then wrap tightly in plastic and chill. Bring to room temperature, cover with foil, and warm in a 300ºF oven until heated through, 15-20 minutes. Uncover and continue to warm to re-crisp croutons and exposed kale edges, about 5 minutes.
