- 6 tablespoons butter
- 2 large yellow onions cut in half and sliced thin
- ⅛ teaspoon kosher salt
- 2 cups low sodium beef broth
- 1 teaspoon Worcestershire sauce
- 1 teaspoon Dijon mustard
- 1 ½ tablespoons cornstarch
- Kosher salt and black pepper to taste
- 1 tablespoon chopped fresh thyme 1 teaspoon dried thyme
Instructions
- Melt the butter in a large skillet over medium heat. Add the onions and salt. Turn or stir the onions every few minutes until they reach a nice golden brown color. If the onions are browning too fast reduce the heat a bit and if they stick to the bottom of the pan deglaze them with a tablespoon of red wine vinegar, wine, or balsamic vinegar.
- Once the onions are browned and caramelized stir in the beef broth (reserving 1/4 cup to mix with the cornstarch), Worcestershire Sauce, and Dijon mustard. Stir to combine and bring to a low boil.
- In a small bowl whisk together the reserved beef broth and cornstarch. Slowly add the cornstarch mixture to the gravy whisking to combine. Boil just until thickened.
- Reduce heat to low and season with salt and pepper to taste. Whisk in the the fresh thyme. For best results serve promptly.
