Ginger-caramelized Onions Topping Recipe

Prepare onions and ginger

Peel and thinly slice onions into half-moons about 1/8-inch thick so they cook evenly. Measure and finely mince fresh ginger (about 2 tablespoons).

Heat pan

Place a large, heavy skillet (preferably 10–12 inches) over medium heat. Add 1 tablespoon neutral oil and 2 tablespoons unsalted butter. Heat until butter is fully melted and just starting to foam but not brown.

Begin cooking onions

Add the sliced onions to the hot pan and spread them into an even layer. Sprinkle 1 teaspoon granulated sugar and 1 tablespoon packed light brown sugar evenly over the onions. Stir to combine so sugar coats onions. Cook over medium heat for 6–8 minutes, stirring every 1–2 minutes to prevent burning, until onions begin to soften and some edges turn translucent.

Lower heat and continue caramelizing

Reduce heat to medium-low. Continue to cook the onions, stirring every 2–3 minutes, for an additional 20–25 minutes. If the pan becomes too dry or onions begin to stick, add 1–2 tablespoons water or stock to deglaze and scrape up fond from the bottom. The goal is a deep golden-brown color without burning.

Add ginger and seasonings

When onions are deeply golden and reduced (about 25–30 minutes total cook time), push them toward the center and add the 2 tablespoons minced ginger to the pan. Cook with the onions for 1–2 minutes until fragrant, stirring constantly so ginger doesn't burn. Sprinkle 3/4 teaspoon kosher salt and 1/2 teaspoon black pepper over the mixture (reserve remaining salt/pepper to taste).

Finish with acid and soy

Deglaze the pan with 1 tablespoon apple cider vinegar and 1 teaspoon soy sauce, stirring to loosen browned bits and to balance sweetness. If the mixture seems too thick, add up to 2 tablespoons water or stock to reach a spoonable, slightly glossy texture. Taste and adjust seasoning with remaining salt and pepper as needed.

Optional herbs and cool

Remove the pan from heat. If using, stir in 1 tablespoon chopped fresh parsley or chives for brightness. Allow the topping to cool slightly for 5–10 minutes before serving so flavors meld.

Storage and use

Transfer cooled topping to an airtight container and refrigerate for up to 5 days, or freeze up to 2 months. Reheat gently in a skillet over low heat or in the microwave. Use as a topping for burgers, grilled meats, flatbreads, sandwiches, roasted vegetables, or creamy polenta.
