Caramelized Onion Jam – Rich, Sweet, and Comforting in Every Bite
Introduction
There’s something deeply comforting about slow-cooked onions transforming into rich, sweet jam. This Caramelized Onion Jam delivers that perfect balance of sweet and savory, with notes of warm olive oil, a touch of sugar, and the brightness of pomegranate juice or apple cider vinegar to round it all out.
Whether you’re layering it on a flatbread, pairing it with cheeses, or spooning it beside baked brie, this spread brings gourmet vibes to even the simplest dishes.
Why I Love This Recipe
This onion jam is what I reach for when I want to turn a slice of crusty bread into something special. It’s versatile, elegant, and shockingly simple. You only need a few pantry staples and a little patience to get that deep, golden flavor that tastes like something out of a fancy bistro.
It’s the kind of quiet kitchen ritual I return to on slower nights, right alongside favorites like easy turkey wings or a bubbling Dorito casserole when I want to balance rich with refined.
Ingredients
- ¼ cup extra virgin olive oil
- ½ cup white sugar
- 4 cups onion, coarsely chopped (yellow or sweet onions work best)
- 1 teaspoon salt
- ¼ teaspoon ground black pepper, plus more to taste
- ½ cup pomegranate juice (or substitute apple cider vinegar)
Ingredient Notes & Swaps
- Onions: Yellow onions give great depth, but sweet onions will yield a milder flavor.
- Pomegranate Juice vs. Vinegar: Pomegranate brings a gentle fruitiness, while vinegar offers sharp brightness. Both work beautifully.
- Oil: Olive oil adds richness, but you could also use unsalted butter for an even more decadent base.
- Optional Add-ins: A sprig of thyme, a pinch of red chili flakes, or even a splash of balsamic can personalize your jam.
How to Make Caramelized Onion Jam
Step 1: Warm the Oil
In a heavy-bottomed skillet over medium heat, warm the olive oil until shimmering but not smoking.
Step 2: Melt the Sugar
Add the sugar and stir gently with a wooden spoon. Let it melt and turn a light amber caramel. Be careful not to burn.
Step 3: Add the Onions
Stir in the chopped onions along with salt and pepper. Reduce the heat to medium-low and cook slowly, stirring often, for about 20–25 minutes.
Step 4: Add Liquid and Simmer
Once the onions are soft, golden, and jammy, add the pomegranate juice (or vinegar). Continue to simmer, stirring occasionally, until the liquid is mostly absorbed and the mixture thickens—another 10–15 minutes.
Step 5: Cool and Store
Remove from heat and let the jam cool to room temperature. Transfer to a jar or airtight container. Refrigerate for up to 1 week.
Tips for Success
- Use a heavy skillet to prevent burning and ensure even caramelization.
- Stir frequently once the onions begin to brown—this helps develop flavor without scorching.
- Let it reduce properly after adding the liquid. The thicker it gets, the better the texture and spreadability.
- Make a double batch—you’ll want more than you think.
