Ingredients

• 4 cups (sliced) yellow onion
• 2 tablespoons butter
• 1 tablespoon olive oil
• 2 tablespoons apple cider vinegar
• 1 tablespoon balsamic vinegar
• 3 tablespoons granular erythritol or monk fruit sweetener
• 1 cup water
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper

Directions

Step 1

Peel and slice the yellow onions into thin, even slices to ensure they cook evenly.

Step 2

In a large skillet or sauté pan, melt the butter and olive oil together over medium heat.

Step 3

Add the sliced onions to the pan, stirring to coat them evenly in the butter and oil mixture.

Step 4

Cook the onions over medium heat for 15 minutes, stirring occasionally, until they begin to soften and turn translucent.

Step 5

Reduce the heat to medium-low and continue to cook the onions, stirring frequently, for another 15-20 minutes until they are deeply caramelized and golden brown.

Step 6

Pour in the apple cider vinegar and balsamic vinegar. Stir well to deglaze the pan, scraping up any browned bits from the bottom.

Step 7

Add the granular erythritol or monk fruit sweetener, water, salt, and black pepper to the pan. Stir to combine.

Step 8

Let the mixture simmer over low heat for 5-10 minutes, stirring occasionally, until it thickens into a jam-like consistency.

Step 9

Taste and adjust seasoning, adding more sweetener or vinegar to balance the flavors as desired.

Step 10

Remove the onion jam from the heat and let it cool slightly before transferring it to an airtight container for storage.

Step 11

Store in the refrigerator for up to 1 week and serve cold or at room temperature as a condiment or topping.
