The combination of sweet onions and a dark rich sauce—which is both sweet and savory—is a classic of both the British and Irish kitchen. Onion gravy is a key component for a comforting and warming meal at home.
"This rich onion gravy had lots of onion and beef flavor and was smooth and delicious, and it was easy to prepare and cook. The gravy would be excellent with Salisbury steaks, cube steaks, or mashed potatoes. The gravy reduced to about 3 cups." —Diana Rattray
2 tablespoons vegetable oil, or cold-pressed rapeseed oil
2 tablespoons unsalted butter, room temperature
2 medium red onions, peeled and thinly sliced
1 teaspoon sugar
1 teaspoon balsamic vinegar
3 cups beef stock
4 teaspoons cornstarch
4 teaspoons cold water
Kosher salt, to taste
Freshly ground black pepper, to taste
Gather the ingredients.
Melt the oil and butter in a large saucepan over a gentle heat to ensure the butter does not burn.
Add the thinly sliced onions to the pan, stir, and cover with a lid.
Cook slowly on low heat for approximately 10 minutes or until the onions are soft and translucent. Take care not to burn them. The onions should not be browned but soft and translucent instead.
Add the sugar and balsamic vinegar to the onions and stir well to ensure the onions are coated. Cover again with the lid and continue to cook for a further 5 minutes, again making sure they don't burn.
Add the beef stock to the pan and stir well. Increase the heat and boil gently, uncovered, for 5 minutes.
In a heatproof jar, liquid measuring cup, or bowl, mix the cornstarch with the cold water to create a thin, lump-free paste.
Pour a little of the hot gravy into the starch mixture and shake or mix thoroughly.
Pour the starch mixture back into the gravy. Raise the heat to high and boil hard for 10 minutes, or until the gravy is slightly thickened.
Season with salt and pepper and keep warm until ready to serve.
- The best onions for this recipe are red onions because they provide just the right amount of sweetness without making the gravy too cloyingly sweet. If you prefer a slightly sharper flavor, then use a standard yellow onion or even a white onion. You can also use large shallots if you like, which will create a much softer finished gravy.
- Use high-quality, flavorful beef stock for the richest possible onion gravy.
- This is such a snap to make, why not make double, even triple the quantity? Use what you need, then freeze the rest in 1-cup portions for 4 to 6 months. Simply defrost in a pan or the microwave.
- For an onion gravy with a little extra flavor, add a few pinches of fresh or dried thyme or finely minced rosemary.
- If you don't have balsamic vinegar handy, use red wine vinegar or swap for malt vinegar for a more traditional flavor.
- If you prefer a thicker gravy, add more cornstarch (also known as corn flour) slurry and boil for a few more minutes to thicken.
- To create a shine on the gravy, take 1 teaspoon of ice-cold butter and whisk it into the finished gravy before serving. The butter will add even more flavor and make the sauce glossy.
- For deeper color, add a few drops of gravy browning sauce.
How to Store and Reheat Leftover Onion Gravy
- Refrigerate leftover onion gravy in a shallow container within 2 hours and eat within 4 days.
- Freeze leftover gravy in airtight freezer containers or zip-close freezer bags for 4 to 6 months.
- Reheat leftover refrigerated or frozen gravy in a saucepan over medium-low heat until hot, at least 165 F.
How do you make brown gravy from scratch without stock?
Beef stock makes the most flavorful gravy, but you can swap it for bouillon in a pinch. Water simply won't give you enough flavor and will leave you with a boring sauce of plain cooked onions. To make this onion gravy vegetarian, use a high-quality vegetable broth, and swap the butter for vegan margarine for vegan gravy.
