Slow Cooker Onion Gravy

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


We love our Slow Cooker Onion Gravy with good old Bangers and Mash as it seems the right comfort food combination for this time of year. Onion gravy is the perfect accompaniment for Toad in the Hole too and also goes down a treat with our nut roast – however you eat it, it’s so much tastier than gravy granules and all that MSG.

Onion gravy is ideal for slow cooking not least because it’s so much easier to caramelise onions in the slow cooker. You get the characteristic rich, sticky flavour (essential to the perfect onion gravy) without the need to stand over a stove stirring onions – simply let the slow cooker do the work for you. It’s the perfect onion gravy for meatlovers and vegetarians alike but using a good quality stock (beef or vegetarian) is essential. I usually opt for a vegetarian stock and I find the gravy isn’t as dark a gravy as using a beef stock, so I add a tablespoon of soy sauce. If you want to heat it up a bit, try adding a teaspoon of horseradish sauce.

Slow Cooker Onion Gravy

Ingredients
Makes:

Approx 1 litre (1 ¾ pints)

  • 1 kg (about 10 medium) onions
  • 3 tablespoons vegetable oil
  • 3 tablespoons butter
  • 1 tablespoon salt
  • 125 ml (½ cup) white wine
  • 500 ml (2 cups) good quality beef or vegetarian hot stock (I used Marigold Swiss Bouillon)
  • 2 tablespoons Balsamic vinegar
  • 1 teaspoon Dijon mustard
  • 1 teaspoon freshly chopped thyme
  • 2 tablespoons cornflour / cornstarch mixed with a little water
  • Optional: 1 tablespoon soy sauce
  • Grease the inside of your slow cooker pot and add the onions, oil, butter and salt.
  • Stir and place on the lid.
  • Cook on low for at least 6 hours (8 hours if you have the time) to caramelise the onions.
  • Once your onions are caramelised, add the wine, hot stock, balsamic vinegar, Dijon mustard and thyme and give it a good stir.
  • Turn your slow cooker to high and whisk in the cornflour water mix.
  • Replace the lid on your slow cooker but this time prop open the lid with a wooden spoon or spatula.
  • Cook on high for 1 to 2 hours.
  • Ladle your onion gravy into a jug or gravy boat.
  • Serve with a big bowl of Perfect Mashed Potato and sausages.

    • Thanks for popping by Kathy, the onion gravy freezes well, I often put portions in the freezer, they come in really handy.

    • Thanks Choclette, the slow cooker really makes light work of caramelising the onions. I’ve never tried Tamari, would give a richer flavour perhaps? I reckon it’s time to try some x

  3. I’ve never thought of using the slow cooker to caramelise onions, what a brilliant idea! I’ll definitely be making this.

      • I finally got round to making it last night – it made a lovely rich, flavoursome gravy to serve with some venison sausages. And because the slow cooker looks after itself, I wasn’t worrying about trying to stop onions from catching while I was cooking the rest of the meal. Definitely one to return to over and over again

        • Thanks Jane, pleased to hear you like the recipe, the slow cooker certainly does free you up to get on with things. I love the sound of venison sausages, I bet they were delicious.

  5. I’ve never had onion gravy, but I love onion soup and gravy and this seems the perfect combination of both. I can definitely see it over mashed potatoes, even roasted veggies. Delish! Perfect for this time of year. One restaurant that I worked in used to make what they called “Smothered Chicken” and it was a chicken breast topped with sauteed onions, a slice of melted provolone cheese and then served with mashed potatoes, the whole thing was covered in gravy, and oh so delicious! I can see this gravy replacing the separate sauteed onions and gravy and making it even more to my taste! And I love that this can be done in a crock pot, my favorite kind of meal!!! Thanks. Pinning!

  6. I love caramelized onion so much. How much more onion gravy? Wow! This looks fantastic – but what if I don’t have a slow cooker? Is it possible for me to make this, too? 🙂 Thank you for sharing this awesome gravy at this week’s Fiesta Friday. It’s nice to have you here. I hope you are having a fab time. 🙂

    • Thanks Jhuls & a pleasure to join in the Fiesta party. You could make this on the stove instead of using the slow cooker, you might need a little more stock & just remember to keep stirring those onions while they’re caramelising xx

  7. I’m so bummed I can’t make this one 🙁 Unfortunately I’m a IBS sufferer and onions and vinegar are a big nono.But I’m drooling just to think about it haha 🙂
    Coming from WAYWOW.

    • Thanks, it’s so much easier letting the slow cooker do all the work. let me know how you get on & thanks for stopping by 🙂

  8. I reeeeeeealy need to buy myself a slow cooker – I keep finding yummy recipes and I can’t make them 🙁

    When I was at uni our treat dinner was sausages, mash, Yorkshire puddings and onion gravy. It’s still one of my favourite dinners now – totally delicious and real comfort food.

    • Thanks Charlotte, you can get some really good bargains with slow cookers at the moment, they seem to come down in price each year. Perhaps you can put one on your Christmas list! Oh yes, onion gravy & Yorkshire pudding, a real treat 🙂
