Ingredients

1 tablespoon olive oil
2 (220 g) medium onions, peeled and sliced thinly
1½ cups (341 g) water or broth - chicken, beef, or veggie (see notes)
1-2 tablespoons butter
½ teaspoon table salt
¼ teaspoon freshly ground black pepper

Instructions

Caramelize the Onions: Heat 1 tablespoon olive oil in a heavy skillet over medium heat. Add 2 medium onions, thinly sliced. Cook, stirring occasionally, until the onions are deep golden brown and very soft, about 30–45 minutes. Watch closely near the end to prevent burning. The onions should reduce to about ½ cup. (This step can be done ahead and frozen.)
Deglaze the Pan: Transfer the onions to a blender. Add 1½ cups water or broth to the skillet and bring to a boil, scraping up any browned bits from the bottom of the pan. Pour most of the liquid into the blender, reserving about ¼ cup.
Blend the Gravy: Blend the onions and broth until completely smooth. Add 1–2 tablespoons butter and blend again. If the gravy seems too thick, add some or all of the reserved broth.
Season and Serve: Season with ½ teaspoon salt and ¼ teaspoon black pepper, adjusting to taste. If using a salty broth, you may need less salt. For extra flavor, stir in fresh herbs, Worcestershire sauce, sour cream, or Greek yogurt before serving.

Notes

Caramelized onions can be frozen for later use.
Adjust thickness with additional broth if needed.
Add a tablespoon or two of sour cream or Greek yogurt for extra richness.
Store leftovers in the refrigerator for up to 3 days or freeze for up to 3 months.
