Ingredients

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

Directions

Step 1

Peel and thinly slice the yellow onions into even slices to ensure uniform cooking.

Step 2

In a large nonstick skillet, melt the butter with the olive oil over medium heat.

Step 3

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

Step 4

Reduce the heat to medium-low and cook the onions for 30 minutes, stirring occasionally to prevent sticking or burning. They should become golden brown and caramelized.

Step 5

Sprinkle the brown sugar over the onions and stir to combine. Cook for another 5 minutes, allowing the sugar to dissolve and add sweetness.

Step 6

Add the balsamic vinegar, red wine vinegar, and water to the skillet. Stir to deglaze the pan, scraping up any browned bits from the bottom.

Step 7

Sprinkle the thyme, salt, and black pepper into the mixture. Stir well to incorporate the flavors.

Step 8

Continue cooking for 10-15 minutes, stirring occasionally, until the mixture thickens and becomes jam-like in consistency.

Step 9

Remove the skillet from heat and let the onion jam cool. Transfer it to an airtight container for storage.

Step 10

Serve immediately or store in the refrigerator for up to two weeks. Enjoy!
