Ingredients

Olive Oil: 2 tablespoons (always go for extra virgin for a more robust flavor)
Yellow Onions: 2 pounds, sliced into thin half-moons (sweet, firm varieties work best!)
Salt: 1 teaspoon (helps draw moisture from onions)
Black Pepper: 1/2 teaspoon (freshly ground for best flavor)
Dark Brown Sugar: 1/4 cup, packed (adds depth and caramel color)
Balsamic Vinegar: 1/4 cup (for a rich, tangy sweetness)
Apple Cider Vinegar: 2 tablespoons (the acidity brings freshness)
Fresh Thyme Leaves: 1 teaspoon (optional, for herbed notes)
Crushed Red Pepper Flakes: 1/4 teaspoon (optional, if you want a kick)

Ingredient Quality & Substitutions

Onions: Look for firm, sweet yellow onions. You can use red onions for a slightly different flavor profile but keep in mind they might be a bit sweeter.
Vinegars: A good quality balsamic will enhance the flavor; don’t skimp on it!
Sugar: If you’re looking for a lower sugar option, you can reduce the sugar slightly or experiment with honey (though this will change the taste).

Prep Notes

Make sure your butter and other liquids are at room temperature before you start cooking for the best incorporation. Prepping your ingredients before you begin will make the cooking process smoother—trust me!

Step-by-Step Instructions

Prepare the Onions: Peel and cut the onions in half, then slice into thin half-moon strips about 1/8 inch thick. The thinner the slices, the better they’ll caramelize!
Heat the Oil: In a large skillet or Dutch oven, heat the olive oil over medium-low heat until shimmering.
Cook the Onions: Add the sliced onions and salt. Stir to coat them in the oil, then cook for 30 to 40 minutes. Keep an eye on them! Stir every 5–10 minutes until they soften up and turn a deep golden hue.
Sweeten the Deal: Once your onions are caramelized to perfection, sprinkle in the brown sugar and pour both vinegars over the top. Stir gently to combine.
Season: Add black pepper, thyme, and crushed red pepper flakes, if using. Your kitchen should smell divine right about now!
Final Cooking: Continue cooking uncovered for another 15 to 20 minutes until the mixture thickens and all the flavors meld together beautifully.
Cool and Store: Remove from heat and let cool slightly. Spoon the jam into clean jars. Allow it to cool completely before sealing and refrigerating.

Chef’s Tips

Timing is Everything: Don’t rush the cooking process. Patience will reward you with the best flavor.
