French Onion Dip
Heat oil in a large skillet over medium-high heat. Add onions and salt; cook, stirring occasionally, until beginning to brown, 6 to 10 minutes. Add broth, scrape up any browned bits, and simmer until the liquid is almost evaporated, 10 to 20 minutes. Reduce heat to medium-low and cook until the onions are deep golden brown, 5 to 8 minutes more. Stir in onion powder, then stir in vinegar and cook until evaporated, 1 to 2 minutes. Remove from the heat and let cool for 20 minutes.Advertisement
