Onion gravy

Published: 06.19.2022 » Last updated: 06.19.2022

Lots of onion, a dark roux, the best vegetable broth and a drizzle of Worcestershire sauce. These are what it takes to make the tastiest onion gravy. Serve with meat, chicken or just plain mashed potatoes.

Mashed potatoes and onion gravy

It’s not very often that I make gravy. But it’s Father’s Day, we were having grilled lamb, and what better sides could go with it but mashed potatoes and gravy? So, while my daughter, Alex, was making kani salad, I made onion gravy.

Making a roux with butter, chopped onion and flour

The default way of making gravy is to start with a roux. That means cooking equal parts of butter and flour. But this is onion gravy so chopped onion was added to butter and flour. The amount of flour was also adjusted so that it’s a little less than the amount of butter. That’s to make sure that the roux stays stirrable throughout the cooking.

Cooking roux with onion until dark

The mixture was cooked with occasional stirring until the flour was toasted to a dark amber and the onion bits were starting to caramelize. I don’t normally time the process. I just trust my eyes and my nose to determine if the roux is ready for the broth.

But, as a helpful guide, I checked the EXIF data of the photos and it took exactly 17 minutes from the time the flour was intergrated into the butter to the time I started pouring vegetable broth. Yes, patience is required because you need the roux to turn a dark brown to make gravy.

Pouring vegetable broth over dark roux to make onion gravy

As I poured the broth with one hand, I stirred with the other. Yes, it looks lumpy at the start. But as you keep pouring broth and stirring, the lumpy mixture will transform into a beautiful gravy.

Adding Worcestershire sauce to onion gravy

The gravy is ready once the mixture thickens to the consistency that you prefer. Some like their gravy really thick while others prefer something more pourable. Just remember that gravy thickens some more off the heat so you want it to be on the thin side before you take the pan off the stove.

But I do two more things to the gravy before serving it. First, I drizzle in a couple of teaspoons of Worcestershire sauce to give it a deeper flavor.

Making a smooth onion gravy with immersion blender

Second, after turning off the heat, I plunge in an immersion blender to liquefy the visible bits of onion. It’s an optional step but I like my gravy smooth with the bold flavor of caramelized onion, a little tang from the Worcestershire sauce and the nutty aroma of flour that had fried in butter.

Onion is an underestimated ingredient. Most people I know get excited over garlic, but onion? Well, onion is just as magnificent as garlic if cooked correctly. Allowing onion to caramelize is one way of maximizing its flavors.
Vegetable broth is used here as it makes a tasty but light gravy. You may substitute chicken or beef broth but know that the flavor and aroma of the gravy will be heavier.
