Slow Cooker Onion Gravy

Sharing is caring!

Slow Cooker Onion Gravy – Make your own rich, sticky onion gravy in your Crock Pot. Perfect with Bangers and Mash, Toad in the Hole or a tasty nut roast! Naturally vegetarian and gluten free.

We love our onion gravy here at the Kitchen Shed. It’s the perfect comfort food and so much tastier than gravy granules!

Caramelised onion gravy made from scratch is so easy and made even easier with your slow cooker. No more standing over the stove top stirring onions to stop them from sticking to the bottom of your pan.

All you have to do is add the onions with some butter and oil to your slow cooker. Pop on the lid and let the slow cooker work its magic.

What equipment do I need ?

• A slow cooker or Crock Pot

What ingredients do I need ?

• Onions – choose firm fresh onions to make a good flavoursome gravy.
• Butter and vegetable oil – to help caramelise the onions.
• Seasoning – I’ve used 2 teaspoons of fine sea salt and 1 teaspoon of freshly ground black pepper. If you use a low salt stock you may want to add more seasoning to taste.
• White wine – adds flavour. The alcohol content burns off during cooking but if you prefer not to use any alcohol, add a little more stock.
• Stock – I used Marigold Swiss Vegetable Bouillon.
• Balsamic vinegar for flavour and colour.
• Dijon mustard – I used Maille.
• Fresh thyme – I used 2 teaspoons. If using dried herbs, remember to half the amount.
• Cornflour / cornstarch mixed with a little water – to thicken the gravy.

How to make Easy Onion Gravy

Slow Cooker Onion Gravy really is easy to make with no roux to make and hardly any stirring. The best onion gravy flavour comes from the caramelised onions. Again the slow cooker makes an easy job of it.

• 

• 

• Add sliced onions along with butter, oil and seasoning to your slow cooker and leave to cook for at least six hours on low.
• Add the rest of the ingredients and give your gravy a good stir.
• Cook on high with the lid propped open for at least one hour. This will help keep the gravy nice and thick.

Recipe Substitutions and Additions

Slow Cooker Onion Gravy can be customised to your family’s tastes.

Onions – I’ve used brown but you can easily substitute red onions or shallots. Either will give a sweeter flavour profile to your finished gravy.

Stock – I’ve used Marigold Swiss Vegetable Bouillon for a vegetarian gravy but you can substitute your favourite stock to make beef gravy or chicken gravy.

Wine – I’ve used white wine but red wine works well, particularly with red onions.

Herbs – I’ve used fresh thyme but sage, bay or parsley make for a tasty gravy too.

Add a tablespoon of redcurrant jelly for an extra fruity sweetness. We love to add a spoon of our Elderberry and Port Jelly for an earthy sweetness.

If you want to heat things up a bit, try adding a teaspoon of horseradish sauce.

What to serve with Caramelised Onion Gravy ?

Mash – serve with a big bowl of perfect mashed potato.
Sausages – we always serve a jug of onion gravy with our homemade vegetarian sausages.
Toad in the hole
Nut Roast
Chips or fries

How long does it keep ?

Slow Cooker Onion Gravy will keep in the fridge for up to four days in a sealed container.

Can it be reheated ?

Reheat in a pan on the stovetop on a medium heat for about 5 minutes, stirring occasionally.

Can I freeze Slow Cooker Onion Gravy ?

Slow Cooker Onion Gravy freezes well. Stir well once defrosted and add 1 teaspoon of cornflour mixed with a small amount of water to the gravy before reheating.
