Description
A deeply flavorful and comforting onion soup featuring slowly caramelized onions in a savory beef broth base.
Ingredients
- 4 medium yellow onions, sliced thin
- 1 quart beef broth
- 2 tablespoons unsalted butter
- 1/2 cup apple cider vinegar or white grape juice (alcohol substitute)
- 2 tablespoons all-purpose flour
- 1/4 teaspoon dried thyme
- 1/8 teaspoon black pepper
- Pinch of salt
Instructions
- Heat the butter in a large heavy-bottomed pot over medium heat until melted and bubbling.
- Add the sliced onions and a pinch of salt, cooking slowly and stirring frequently for about 18-22 minutes until they are deeply caramelized and soft.
- Sprinkle the flour over the onions and stir constantly for 1 minute to cook off the raw flour taste.
- Pour in the apple cider vinegar or grape juice to deglaze the pan, scraping up any browned bits from the bottom, and cook for 2 minutes.
- Add the beef broth, black pepper, and dried thyme, then bring the mixture to a boil.
- Reduce heat to medium-low and simmer uncovered for 20-25 minutes until the soup has thickened slightly.
Notes
If you prefer a gluten-free version, substitute the flour with a cornstarch slurry added at the end. For the alcohol substitute, you can also just use extra beef broth.
