Ingredients for servings
2 tablespoons olive oil
1 medium onion, finely chopped
2 garlic cloves, finely grated
2 sprigs thyme
1 small shallot(s), finely chopped
1 cup(s) sour cream
0.25 cup(s) finely chopped chives
1 tablespoon(s) fresh lemon juice
kosher salt & freshly ground pepper
anything dippable, from chips to celery sticks
Heat oil in a small skillet over medium. Cook onion, garlic, and thyme, stirring occasionally, until onion is deep golden brown and very soft, 35–40 minutes. Discard thyme and let cool.
Mix caramelized onions, shallot, sour cream, chives, and lemon juice in a medium bowl; season with salt and pepper. Let sit 30 minutes to let flavors meld. Serve with potato chips for dipping.
Dip can be made one day ahead; cover and chill.
