Onion Gravy
A comforting and delicious sauce that elevates many dishes, onion gravy is easy to make with just a few ingredients and brings a touch of home-cooked goodness to your meals.
Ingredients
Main ingredients
- 6 tablespoons butter
- 2 large yellow onions, cut in half and sliced thin
- ⅛ teaspoon kosher salt
- 2 cups low sodium beef broth Reserve ¼ cup for mixing with cornstarch
- 1 teaspoon Worcestershire sauce
- 1 teaspoon Dijon mustard
- 1 ½ tablespoons cornstarch
- Kosher salt and black pepper to taste
- 1 tablespoon chopped fresh thyme (or 1 teaspoon dried thyme)
Instructions
Preparation
- Melt the butter in a large skillet over medium heat.
- Add the sliced onions and kosher salt to the skillet. Stir or turn the onions every few minutes until they become golden brown.
- If the onions brown too quickly, lower the heat. If they stick, deglaze the pan with a tablespoon of red wine vinegar, wine, or balsamic vinegar.
Cooking
- Once the onions are nicely browned and caramelized, stir in the beef broth (save ¼ cup for mixing with cornstarch), Worcestershire sauce, and Dijon mustard. Mix well and bring to a gentle boil.
- In a small bowl, whisk together the reserved beef broth and cornstarch.
- Slowly add the cornstarch mixture to the skillet while whisking to combine. Boil until the gravy thickens.
- Reduce the heat to low and season with salt and pepper to taste. Finally, whisk in the fresh thyme. Serve promptly for the best flavor.
Notes
Cooking the onions slowly is key to getting that rich, caramelized flavor. Experiment with herbs like fresh rosemary or parsley for different flavors. For thicker gravy, you can add more cornstarch mixed with broth first.
