Cheesy Kale Casserole Recipes

Steps:

• Preheat the oven to 400 degrees F.
• Remove the tough, fibrous ribs from the kale leaves and discard the ribs. Tear the leaves into bite-size pieces. Reserve any tender stems and finely chop. Keep the leaves and chopped stems separate.
• Meanwhile, bring a large pot of salted water to a boil over high heat and fill a large bowl with ice water. Add the kale leaves to the boiling water and cook until tender and bright green, 1 to 2 minutes. Use a slotted spoon or tongs to transfer the kale to the ice water bath. Once completely cool, drain well. Bring the water back to a boil, then add the squash. Cook until just tender, about 3 minutes. Drain well and reserve the pot.
• Place the pot over medium-high heat. Melt the butter, then add the reserved kale stems, garlic, onion, 1/2 teaspoon salt and several grinds of pepper. Cook until the vegetables are tender, about 4 minutes. Stir in the kale leaves, squash, heavy cream, cream cheese, Parmesan and nutmeg until well combined and smooth. Reduce the heat to medium and cook until the sauce has reduced and thickened slightly, about 5 minutes. Season with salt and pepper.
• Transfer to a 2-quart baking dish. Stir together the breadcrumbs, parsley and a pinch of salt and pepper in a small bowl until combined, then sprinkle evenly over the top of the casserole. Bake until golden brown and bubbling at the edges, 15 to 20 minutes.

Steps:

• If you're planning to bake this immediately, preheat the oven to 350 degrees F. If you're prepping this the day before, no need to preheat now.
• In a skillet (or 4-quart braiser that you can put in the oven), heat the butter over medium heat. Add the onion and cook until softened, 5 to 7 minutes.
• Combine the sourdough, mozzarella, Gruyere and kale with the buttery onion mixture, either in a 9-by-13-inch casserole dish or in the braiser.
• In a large bowl, whisk together the milk, cream, mustard, salt, nutmeg, eggs, thyme, hot sauce and a bunch of turns of pepper. Pour into the casserole dish over the bread mixture. Top with another little sprinkle of Gruyere. Cover with foil and bake immediately or refrigerate up to 24 hours.
• Bake, covered, for 30 minutes. Remove the foil and continue to bake until browned on top and set throughout, about another 30 minutes.

Steps:

• Preheat oven to 350 degrees. Spray rectangle baking dish with nonstick spray. Melt butter and add onions to a saucepan, cook until translucent. Add kale in batches and cook until wilted. Sift flour over kale mixture. Cook 2-3 minutes then add half and half, 1 cup parmesan, and cream cheese. In another bowl combine 1 cup parmesan, panko, and spices. Sprinkle over kale in baking dish and cook 35 minutes until brown and bubbly.

Steps:

• Preheat oven to 350°F. Toast bread in a single layer on a rimmed baking sheet until beginning to dry out but not yet browned, 8-10 minutes.
• Meanwhile, heat oil in a 12" cast-iron skillet over medium-high. Arrange mushrooms in a single layer and cook, undisturbed, until lightly browned, about 3 minutes. Add garlic, season generously with salt and pepper, and cook, tossing and reducing heat if needed, until mushrooms are golden brown all over, about 2 minutes. Push to one side and melt 1 Tbsp. butter in center of skillet. Add leeks and season with salt and pepper. Cook, stirring often and mixing into mushrooms, until softened, about 5 minutes. Add kale by the handful, tossing to wilt slightly after each addition, and cook, tossing often, until all of the kale is mostly wilted, about 4 minutes. Transfer kale mixture to a medium bowl. Let skillet cool slightly, then wipe out and coat with remaining 1 Tbsp. butter.
• Whisk eggs, mustard, 1 tsp. salt, and 1/2 tsp. pepper in a large bowl until no streaks remain, then whisk in milk. Arrange half of bread in skillet. Cover with half of kale mixture, then top with half of Gruyère and half of Parmesan. Top with remaining bread and kale mixture; pour egg mixture over. Press down on strata with a spatula to help bread absorb egg mixture. Scatter remaining Gruyère and Parmesan over.
• Bake strata until golden brown and no liquid seeps out when a knife is inserted into the center, 35-40 minutes. Let cool slightly before serving.
• Do Ahead
• Strata can be baked 3 days ahead. Let cool completely; cover and chill.

Steps:

• Preheat oven to 450°F. Bring vinegar and 1/3 cup water to a simmer in a small pot. Remove from heat. Add raisins, cover, and let sit until ready to use.
• Divide squash, thyme, and garlic between 2 rimmed baking sheets; arrange in a single layer. Toss with 2 Tbsp. oil, 1/2 tsp. salt, and 1/2 tsp. pepper. Roast 12 minutes. Toss, then add hazelnuts to 1 section of 1 sheet. Continue to roast until hazelnuts are toasted and browned and squash is tender and cooked through, about 6 minutes more.
• Whisk ricotta and cream in a medium bowl until smooth. Add 6 oz. mozzarella, 3/4 tsp. salt, and remaining 1/2 tsp. pepper and whisk to combine. Remove thyme leaves from stems and add to cheese mixture. Coarsely chop garlic, add to cheese mixture, and stir to combine.
• Transfer hazelnuts to a large bowl. Add panko, 2 Tbsp. oil, and remaining 1/2 tsp. salt and toss to combine. Set aside 1/4 cup panko mixture.
• Drain raisins. Add kale, squash, and raisins to remaining panko mixture in large bowl and toss to combine.
• Grease 2-qt. baking dish with oil. Add half of squash mixture, then dollop with half of cheese mixture. Top with remaining squash mixture, then dollop with remaining cheese mixture. Top with remaining 2 oz. mozzarella and reserved 1/4 cup panko.
• Bake casserole until mozzarella is melted and browned in spots and edges are bubbling, 12-15 minutes. Let cool slightly before serving.

Steps:

• Preheat oven to 350°. In a large skillet, combine cream, sausage and garlic; bring to a boil. Reduce heat; simmer, uncovered, 3-5 minutes or until slightly thickened. Stir in kale. Add bread crumbs and cheese; toss to combine., Transfer to a greased 8-in. square baking dish. Bake 25-30 minutes or until edges are golden brown.

Steps:

• Heat the oven to 350 degrees. Grease a 9-by-13-inch baking dish with the butter.
• In a large skillet, cook the bacon over medium-low until crispy, 8 to 10 minutes. Transfer the bacon to a plate lined with paper towels and set aside. When cool enough to handle, roughly chop bacon.
• Pour off all but 2 tablespoons of the bacon grease from the pan. Heat the skillet over medium, add the onion, and sauté until soft and lightly browned, 2 to 4 minutes. Add the kale and garlic and sauté until the garlic is tender and fragrant, another minute. Remove from the heat and stir in the chopped bacon.
• In a large bowl, whisk together the eggs, milk and mustard. Add 1/2 cup mozzarella, 1/2 cup Gruyère, the hash browns, 1 teaspoon salt and 1/2 teaspoon pepper; stir to combine.
• Stir the kale mixture into the eggs, then pour into the buttered dish. Top evenly with the remaining mozzarella and Gruyère. Cover with foil.
• Bake for 45 minutes. Remove the foil and bake, uncovered, until the top is lightly browned and bubbly, another 15 minutes. Serve hot. (Cooled casserole will keep, covered, in the refrigerator for 3 to 5 days.)
