I would say getting your gravy just right probably takes about 20-30 minutes, but bear in mind that while it’s cooking, usually there’s a main dish being cooked at the same time, so it’s not really much of a stretch.

That said, you could always make a big batch of onion gravy ahead of time and freeze portions for when you need it, which would be perfect for those meals you’ve defrosted alongside them for a midweek win, or maybe if you’re having a pre-prepared dish like a pie, for example. 

Here I will show you how to make Onion Gravy that’s super simple but also has a little something extra.

  • White onions – These are fine to use if you prefer, I quite like the sweetness from red onions. White onions will become sweet but you may need to cook them a little longer.

Top tips for making Onion Gravy


Feel free to blend this with a handheld blender like this one if you’d prefer a smooth texture.

Onion chunks

If you want the onions to stay in nice neat pieces as they cook, cut them in half moons root to tip (like in my prep photo). If you cut them the opposite way, they tend to disintegrate more.

What is the secret to good gravy?

As well as getting a good, easy recipe that you’ll remember, make sure the seasoning, texture and thickness is to your liking before serving.

Once you’ve done this a few times you’ll be perfecting it without thinking. And always make sure you’ve heated it up until it’s piping hot.

My gravy is lumpy – help!

This is perhaps because you haven’t stirred in the liquid to the flour slowly enough, so lumps have formed and they’re difficult to get rid of.

Make sure you add the stock a little at a time while constantly stirring. If all else fails, blend the gravy as I usually do!

Can I add anything to this gravy recipe?

If the dish calls for it, you could always add any juices from the meat you’re cooking or a splash of wine. You can try any preferred herbs, garlic, or even a little cream.

    Very nice gravy, made it twice, the second time with Dijon and one less tablespoon of Worcestershire Sauce which I preferred but honestly both were delicious!
