If you love onions, this is a must-try. If I fixed it, my hubby would eat it every night. This quick and easy gray will elevate your next meal. If you like gravy recipes, try white gravy, sausage gravy, or beef tips and gravy.
Onion Gravy Ingredients
For this recipe, you need butter, onions, salt, beef broth or vegetable (for the vegetarian version), Worcestershire Sauce, Dijon mustard, cornstarch, freshly ground black pepper, and fresh herbs such as thyme, sage, parsley, rosemary, or chives.
How To Make Onion Gravy
First, melt the butter in a large skillet over medium heat. Then add the onions and a couple of pinches of 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 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 fresh thyme. For best results, serve promptly.
Beth’s Tips for Perfect Onion Gravy
- Caramelizing onions is not difficult, but it can be time-consuming, so plan appropriately. It can take up to 45 minutes. Of course, there are different degrees of caramelization, and for this particular gravy, you don’t have to go the whole enchilada.
- Slice those onions thin. They will be so much easier to caramelize if they are thin.
- Stir the onions, but not too frequently, as they must have some surface time with the hot skillet to caramelize.
- For vegetarian gravy, use vegetable broth.
- Other fresh herbs include sage, parsley, rosemary, and chives.
Ways to Serve Onion Gravy
Spoon it over mashed potatoes, rice, and egg noodles. You can also use it in your favorite Salisbury steak recipe, pork schnitzel recipe, poutine recipe, or bangers and mash recipe. Serve it with meatballs, meatloaf, chicken fried steak, or pan-fried pork chops.
