Scale
Ingredients
- 3 pounds yellow onions, peeled, sliced, and cut into quarter-moons (about 4 large onions)
- 2 tablespoons unsalted butter, melted
- 2 tablespoons olive oil
- 2 teaspoons kosher salt, plus more as needed
- Optional: Freshly ground black pepper
Instructions
- Prepare the Ingredients: Peel the yellow onions, slice them thinly, and cut into quarter-moon shapes to ensure even cooking and maximum caramelization.
- Combine in Crockpot: Place sliced onions into the crockpot. Add melted unsalted butter, olive oil, kosher salt, and optionally freshly ground black pepper. Stir to coat onions evenly with the fat and seasoning.
- Cook Slowly: Cover the crockpot and cook on low for about 14 hours to allow the onions to caramelize deeply. Stir the onions every 2 to 3 hours to ensure even cooking and prevent sticking.
- Check and Adjust Seasoning: After cooking, taste the onions and adjust salt or pepper as needed to enhance flavor before serving or using in recipes.
Notes
- Stirring occasionally during cooking is essential to prevent onions from burning or sticking.
- For sweeter onions, choose yellow or Vidalia varieties.
- These caramelized onions can be stored in the refrigerator for up to a week or frozen for longer storage.
- Use in burgers, sandwiches, soups, or as a topping for steaks and pizzas.
