CARAMELIZED ONION SPREAD RECIPES

Steps:

• Prepare the dough: In a large bowl, whisk together flour, sugar, 1 1/2 teaspoons kosher salt and 1 1/2 teaspoons black pepper. Add butter and 1 cup grated Gruyère to the flour mixture and toss to coat. Using your fingertips, pinch the butter and cheese into the flour to make pebble-size pieces. Drizzle in the ice water and stir to make a shaggy dough. Dump the dough onto a large sheet of plastic wrap and knead a few times to combine. Wrap in plastic and refrigerate for at least 4 hours.
• Prepare the onions: In a large skillet, melt the butter over medium-high heat. Add onions and thyme sprigs, season with 1 teaspoon salt and 1/2 teaspoon pepper and cook, stirring occasionally, until the onions are translucent and lightly golden on the edges, 20 to 25 minutes. Reduce the heat to medium, add broth and sherry and cook until the onions are browned and the liquid has mostly evaporated but the mixture is still saucy, 16 to 18 minutes. Transfer to a bowl and set aside to cool for at least 30 minutes.
• Heat the oven to 375 degrees. Roll the dough into a 13-inch round on a sheet of parchment. Spread the cooled caramelized onions on the dough, leaving a 1- to 2-inch border. Fold the edges in, over the onions, transfer to a baking sheet and bake until the dough is golden brown and some of the onions have browned on the edges, 40 to 50 minutes, rotating the galette halfway into the baking process.
• Remove galette from the oven and sprinkle remaining 1/3 cup grated Gruyère on the crust. Bake another 5 minutes to melt the cheese. Remove and let rest for 10 minutes before slicing. Top with remaining thyme leaves, for garnish.

Steps:

• Heat olive oil in a large heavy-bottomed Dutch oven over medium high. Add shallots and thinly sliced garlic, and season with salt and pepper. Cook, stirring occasionally, until the shallots have become totally softened and caramelized with golden-brown fried edges, 15 to 20 minutes.
• Add red-pepper flakes and anchovies. (No need to chop the anchovies; they will dissolve on their own.) Stir to melt the anchovies into the shallots, about 2 minutes.
• Add tomato paste and season with salt and pepper. Cook, stirring constantly to prevent any scorching, until the tomato paste has started to cook in the oil a bit, caramelizing at the edges and going from bright red to a deeper brick red color, about 2 minutes. Remove from heat and transfer about half the mixture to a resealable container, leaving the rest behind. (These are your leftovers to be used elsewhere: in another batch of pasta or smeared onto roasted vegetables, spooned over fried eggs or spread underneath crispy chicken thighs.)
• To serve, cook pasta according to package instructions in a large pot of salted boiling water until very al dente (perhaps more al dente than usual). Transfer to Dutch oven with remaining shallot mixture (or a skillet if you are using the leftover portion) and 1 cup pasta water. Cook over medium-high heat, swirling the skillet to coat each piece of pasta, using a wooden spoon or spatula to scrape up any bits on the bottom, until pasta is thick and sauce has reduced and is sticky, but not saucy, 3 to 5 minutes.
• In a small bowl, combine parsley and finely chopped garlic clove, and season with flaky salt and pepper. Divide pasta among bowls, or transfer to one large serving bowl, and top with parsley mixture and a bit more red-pepper flakes, if you like.
