Bacon & Caramelized Onion Topping

I am not really that much of a condiment person. Whenever friends come over they’re horrified when they open my fridge and find that the door shelves are empty. At any given time, MAYBE I have ketchup, Dijon or Calabrian chile paste, but not much else. However, this is the kind of condiment I can get behind. You’ll see me using this in a frittata, on a grilled cheese or smash burger, or to amp up a dip.

Bacon & Caramelized Onion Topping
Ingredients
- 1 pound bacon, cut into ½-inch pieces
- 1 tablespoon unsalted butter
- 8 cups yellow onions, sliced into ¼-inch half-moons (about 2 pounds)
- Kosher salt
Instructions
- In a large heavy-bottomed sauté pan, melt the butter over medium heat.
- Add the bacon and cook, stirring often, until crispy, about 10 minutes.
- Using a slotted spoon, transfer the bacon to a paper towel-lined plate, leaving the rendered fat in the pan.
- Add the onions and stir to coat with the fat; cover and steam for 10 minutes.
- Add ½ teaspoon of salt and stir with a wooden spoon, scraping any brown bits from the bottom of the pan.
- Cook, stirring often, until deep golden brown, about 50 minutes. If the onions begin to stick to the bottom of the pan, add a couple tablespoons of water to deglaze.
- Remove from the heat, stir in the bacon and adjust the seasoning, to taste.
- Keep warm until ready to serve.
