Oven Caramelized Onions Recipes

Steps:

• Preheat the oven to 400°F.
• Line a baking sheet with aluminum foil.
• Add the onions to the prepared baking sheet and top with the remaining ingredients. Toss to combine thoroughly, separating the onion slices.
• the onion slices.
• Bake for 1 hour, tossing every 10 minutes with silicone tongs.
• By now the onions should be softened and golden in color. If it appears dry, add a splash more broth or water.
• Continue to bake for 15-20 minutes, tossing twice.
• Remove the onions from the oven and season with more salt and pepper if desired.

Steps:

• Preheat oven to 400 degrees.
• Remove papery skin from onions. Slice onions in quarters from top to bottom so each quarter includes some of the core to hold it together.
• Set quarters in a small baking dish, pointy side up. Season with salt and pepper, add stock and balsamic and top with herbs. Cover tightly with aluminum foil and bake for 45 minutes. Remove foil and bake for 30 more watchful minutes or until onions are very caramelized and the liquid is reduced to a thick glaze.

Steps:

• Halve both onions through root end. Using the tip of your knife, cut a V-shaped notch around root to remove it (this will ensure that all slices separate when you cut the onion).
• Place 1 onion half on your cutting board so root end is facing you, then thinly slice onion lengthwise, starting at one side and working all the way to the other (so your knife runs through the root halfway through, not starting or ending at the root end). You're going for slices that are 1/4"-1/8" thick.
• Repeat same slicing procedure for remaining onion halves. It's a lot of onion! But it will cook down quite a bit, so it's best to start with a large quantity.
• Heat 2 Tbsp. butter in a large saucepan over medium until melted and sizzling. You can use a skillet to cook the onions, but a pan with high sides will keep the onions from flipping out onto your stove. Using a pan that also has a wide base gives water room to evaporate, allowing the onions to caramelize rather than steam.
• Instead of dumping in all of the onions at once, which would fill the pot and make it hard to stir (which would then cause the ones on the bottom to cook faster), start by adding just a couple of large handfuls to the pot. Cook, stirring, until onions are soft and starting to turn translucent, 1-2 minutes. Stir in a few more handfuls of onion and repeat cooking and stirring process until you've added all the onions. Season with a pinch of salt.
• Reduce heat to medium-low and continue to cook onions, stirring every few minutes to prevent them from sticking and coloring too much in any one place, until blonde-colored, 15-20 minutes. This is the point of doneness for French onion soup! If you feel like onions are getting too brown around the edges or they're sticking, reduce your heat a bit.
• If you're going for onions that are both softer and more caramelized (say for a patty melt or onion dip), keep cooking, stirring on the regular, until onions are unmistakably golden brown, another 15-20 minutes. Because most of the water has cooked off at this point, there might be some bare spots where the pot could start to burn. If this happens, stir in a splash of broth or water. The liquid will dissolve the cooked-on bits, which the onions will re-absorb.
• For extra-dark onions, the kind that make a great burger topping, cook until they start to almost blacken around the edges and go slightly crisp, another 10-15 minutes. This requires constant attention so they don't burn. No one said caramelized onions were quick!
• Let onions cool in the saucepan, then use or transfer to an airtight container and chill. They will keep up to 1 week.

Steps:

• In an 8-quart Dutch oven or heavy pot, melt butter over medium-high. Add onions and salt. Cook, stirring often, until softened and just beginning to brown, 35 minutes.
• Reduce heat to medium. Add sugar and cook, stirring often to scrape up any browned bits stuck to bottom of pot, 35 to 40 minutes (lower heat, if bottom of pot begins to scorch).
• When done, onions should be deep golden brown and have a jam-like consistency. Remove from heat; season with salt. Let cool completely.
