I absolutely love to serve my family a hearty meal. Sausage and mash, with onion gravy, is ALWAYS a hit. This is my ultimate onion gravy recipe and it is the best onion gravy for sausages.
You can make this a gluten free onion gravy, by switching the flour, and it still packs a brilliant flavour.
What I love about this onion gravy is that I can make it in advance, even freeze it in batches, and then it is on hand when I want to give my family a flavoursome meal without much effort.
This onion gravy goes great with toad in the hole, air fryer mashed potatoes, roast dinner, a Ninja Foodi roast chicken, air fryer sausages and so many other delicious dinners.
When the nights are still cold I really enjoy eating comfort food. Cooking a nice meal for my family is my way to de-stress after a long day. I'll put some good music on, get a nice cup of tea and serve up a feast that I know my family are going to enjoy.
I love to prepare this in advance, and give it a little warm through before serving too! It is a great way to have dinner half prepared when the witching hour starts post school! I also love to use this as a dip for these leftover sausage rolls.

Ingredients for onion gravy recipe:
15g butter
1 large onion (sliced)
1 teaspoon sugar
15g plain flour (or gluten-free flour)
350ml beef stock
A splash of Worcestershire sauce (can be left out if need be due to allergies) You can even replace this with a little tiny bit of Marmite if you like that instead! Marmite roast potatoes are delicious too!
Method for onion gravy:
Melt the butter in a pan and then add your onions in.
Cook for 1-2 minutes then sprinkle over the sugar.
Stir regularly over a medium heat for 10-15 minutes until the onions have soften and are caramelised.
Sprinkle over the flour. Give it a stir to coat all of the onions evenly. Cook for 1-2 minutes.
Pour in your stock. If you're using a stock cube then just crumble this over the onions and then add your water. If you want to make this a rich onion gravy you can add a little red wine!
Bring the gravy to the boil. Reduce the heat to a simmer and cook for a couple of minutes until the gravy thickens up. Add the Worcestershire sauce if using, or Marmite. Season with a salt and pepper to taste.
Can you make rich homemade onion gravy without flour?
Personally I feel that the flour is really needed to add a richness to this dish. if you're happy with a thinner sauce then you could leave this out. You could also use cornflour or even Xanthan Gum to help thicken this up, but it may be a little stringy if you use too much Xanthan Gum.
Want to make a gluten free onion gravy?
Just use your favourite gluten free flour! I've used Doves Farm gluten-green plain flour for this before and added a tiny tiny pinch of Xanthan Gum to help it thicken up a little. It works really well.

Want to add some extra flavour?
I love to use thyme, rosemary, mustard, onion chutney or even a little Bisto want I want to make a cheats onion gravy.
Can you make onion gravy with Bisto?
Absolutely. If you're looking for more of a cheats onion gravy then caramelise the onions and then add Bisto. You can make it nice and thick by adding less water and it's a great way to make onion gravy with less hassle.

How to cut onions for onion gravy?
I love to slice onions in half and then I will slice downwards, from near the root, as this makes lovely slices that stay together well.
In the photograph on this recipe I sliced them across, and as you can see they've held up very well and are still delicious.
What is the secret ingredient for good gravy?
I love to add a little Marmite to mine. This packs a punch of flavour and I also find that even people that aren't Marmite fans will enjoy my onion gravy when it contains a ¼ teaspoon of Marmite.

Why does gravy go bitter?
If you let the roux burn a little then you're going to have a bitter aftertaste to your gravy. You can avoid this by keeping a close eye on the pan.
How to make onion gravy:
Onion gravy
Ingredients
- 15 g butter
- 1 large onion
- 1 teaspoon sugar
- 15 g plain flour
- 350 ml beef stock
- Splash Worcestershire sauce
Instructions
- Melt the butter in a saucepan or frying pan then add the onions in.
- Cook for 1-2 minutes then sprinkle with the sugar.
- Stir regularly while cooking on a medium heat for 10-15 minutes. You’ll know when the time is up as the onions will be soft and they will have become caramelised thanks to the butter and sugar.
- Sprinkle the flour over the onions. Give it a stir to ensure that all the onions are coated. Cook for a further 1-2 minutes.
- Pour in your stock if using fresh. If you’re using a stock cube then save yourself some effort by crumbling the stock cube in and then measuring in the required water.
- Bring the onion gravy to the boil. Reduce the heat to a simmer and allow the onion gravy to thicken up. Add a splash of Worcestershire sauce. If it needs a little more seasoning then add a grind of fresh black pepper.

Most defiantly will make again...
Thanks so much!
Loved it! I tried another recipe before this one and tossed it out. This was so rich and creamy. So much flavor! Thank you!!
I'm so pleased to hear that - thanks for letting me know! x
can you make ahead (in large quantities) and then freeze in smaller batches?
Yes, absolutely! I've made 4x the recipe before and then froze with no issues. When re-heating make sure it is piping hot and you can re-heat from frozen as long as you keep an eye on the saucepan to prevent bubbling over.
Next time I’m omitting the sugar. I felt like it ruined it for me even though it was just a tsp. Also I had to add better than bouillon because without it there wasn’t enough flavor.
Thanks for sharing your feedback. I hope next time the recipe is more successful for you.
Also, bouillon is what I refer to as stock in the recipe, made with a cube, I think perhaps you're in the US?
