Recipe Information
Ingredients
- 6 large yellow onions
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon kosher salt
- 1 teaspoon brown sugar (optional)
Instructions
Peel the onions and slice them into thin, even rings or half-moons, about 1/4-inch thick.
Grease the inside of your slow cooker with a light layer of olive oil or non-stick cooking spray to prevent sticking.
Place the sliced onions into the slow cooker, filling it close to the top as they will shrink significantly during cooking.
Melt the unsalted butter in a small saucepan or microwave, and drizzle it over the onions.
Add the olive oil, kosher salt, and optional brown sugar (if you prefer a sweeter caramelized onion) to the slow cooker.
Toss the onions gently to coat them evenly with the butter, oil, and seasonings.
Set the slow cooker to LOW and cook for 8-10 hours, stirring every 2-3 hours to ensure even caramelization. If the edges start to brown too quickly, reduce the cook time slightly or stir more frequently.
Check the color and texture after 8 hours – the onions should be a deep golden brown and soft. If they aren’t fully caramelized, continue cooking for another 1-2 hours.
Once finished, let the onions cool completely before transferring them to an airtight container or jar.
Store in the refrigerator for up to one week or freeze in small portions for up to three months.
