Ingredients

• 4 large yellow onions
• 2 tablespoons olive oil
• 1 tablespoon unsalted butter
• 3 tablespoons balsamic vinegar
• 2 teaspoons brown sugar
• 0.5 teaspoon kosher salt
• 0.25 teaspoon black pepper
• 1 teaspoon fresh thyme (optional)

Directions

Step 1

Peel and slice the onions into uniform 1/4-inch thick rings or half-moon slices, depending on your preference.

Step 2

Heat a large skillet over medium heat and add the olive oil and butter. Stir until the butter melts and the mixture is hot.

Step 3

Add the sliced onions to the skillet and spread them out evenly. Sprinkle with the kosher salt and toss to coat the onions in the oil and butter mixture.

Step 4

Cook the onions over medium heat for 10 minutes, stirring occasionally to prevent burning and ensure even cooking.

Step 5

Reduce the heat to low and continue cooking for an additional 15 minutes, stirring occasionally, until the onions become golden brown and start to caramelize.

Step 6

Sprinkle in the brown sugar and pour in the balsamic vinegar. Stir to coat the onions evenly in the mixture.

Step 7

Cook for another 5 minutes until the balsamic vinegar reduces slightly and the onions become glossy and richly caramelized.

Step 8

Taste and adjust seasoning with additional salt and black pepper if needed. Stir in fresh thyme if using for added flavor.

Step 9

Remove from heat and serve warm. Balsamic onions can be stored in an airtight container in the refrigerator for up to 5 days.
