Ingredients

• 4 large yellow onions
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 3 tablespoons balsamic vinegar
• 2 tablespoons brown sugar
• 1 teaspoon fresh thyme leaves
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 0.25 cup water

Directions

Step 1

Peel the onions and slice them thinly into evenly sized half-moons.

Step 2

In a large skillet, heat the olive oil and butter over medium heat until the butter has melted.

Step 3

Add the sliced onions to the skillet and stir to coat them evenly with the oil and butter mixture.

Step 4

Sprinkle the onions with the salt and pepper, and stir again to combine.

Step 5

Reduce the heat to medium-low and allow the onions to cook, stirring occasionally, for 25–30 minutes until they are golden brown and caramelized. Be careful not to let them burn.

Step 6

Once the onions are caramelized, add the brown sugar, balsamic vinegar, fresh thyme leaves, and water to the skillet.

Step 7

Stir well to combine and simmer for an additional 10–15 minutes over low heat, allowing the mixture to thicken into a jam-like consistency. Stir occasionally to prevent sticking.

Step 8

Taste and adjust seasoning if necessary. Remove from heat and let cool slightly.

Step 9

Transfer the caramelized onion jam to a clean jar or container. Store in the refrigerator for up to 2 weeks.

Step 10

Serve warm or at room temperature as a condiment for cheese boards, sandwiches, burgers, or roasted meats.
