In our homemade version of French onion dip, we simmer chopped onions in broth and use reduced-fat sour cream and yogurt for the familiar rich and creamy flavor. All told, our version has 12 grams less fat and nearly 50 percent less sodium per serving than the original.
- 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.
- Combine sour cream and yogurt in a medium bowl. Stir in the onion mixture. Chill for at least 30 minutes to blend flavors.
