Ingredients

• 4 large yellow onions
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 2 tablespoons granulated sugar
• 2 tablespoons balsamic vinegar
• 1 tablespoon red wine vinegar
• 0.5 teaspoons salt
• 0.25 teaspoons black pepper (freshly ground)

Directions

Step 1

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

Step 2

Heat a large, heavy-bottomed skillet over medium heat and add the olive oil and butter. Allow the butter to melt completely.

Step 3

Add the sliced onions to the skillet and stir to coat them evenly in the oil and butter mixture. Spread them out in an even layer.

Step 4

Reduce the heat to medium-low and cook the onions, stirring occasionally, for about 25-30 minutes. Be patient as the onions slowly soften and caramelize. Adjust the heat if necessary to prevent burning.

Step 5

Once the onions have turned golden brown and have a jam-like consistency, sprinkle the sugar over them and stir well.

Step 6

Add the balsamic vinegar and red wine vinegar, stirring to deglaze the pan and incorporate the liquid into the onions.

Step 7

Season the mixture with salt and freshly ground black pepper, adjusting to taste.

Step 8

Continue cooking the marmalade for another 10 minutes, stirring frequently, until the mixture becomes thick and glossy.

Step 9

Remove the skillet from heat and allow the marmalade to cool before transferring it to a glass jar or airtight container.

Step 10

Store the marmalade in the refrigerator for up to one week. Serve it slightly warmed or at room temperature with your favorite dishes.
