Sometimes I enjoy a face mask or a little self-care as a parent while I cook. Today I’m bringing you my ultimate onion gravy recipe! It takes minimal prep and it tastes delicious too! It goes perfect for a slow cooker whole chicken and my air fryer roast potatoes.

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 as a parent.

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!

Homemade onion gravy recipe on mashed potato

Ingredients for onion gravy recipe:

15g butter

1 large onion (sliced)

1 tsp 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! 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 are soft and have 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 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.

  • 15 g butter
  • 1 large onion
  • 1 tsp sugar
  • 15 g plain flour
  • 350 ml beef stock
  • Splash Worcestershire sauce


  1. Melt the butter in a saucepan or frying pan then add the onions in.
  2. Cook for 1-2 minutes then sprinkle with the sugar.
  3. 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.

  4. 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.
  5. 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.
  6. 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.

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?

can you make ahead (in large quantities) and then freeze in smaller batches?


Sunday 29th of March 2020

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.

Loved it! I tried another recipe before this one and tossed it out. This was so rich and creamy. So much flavor! Thank you!!
