Onion Sauce is a cooking Basic recipe

Onion sauce is a recent discovery for me.

I eat a largely plant-based diet.

Over the last 35 years of being a non-meat eater, I’ve found many ways to pack my meals with delicious flavour.

Finding an onion sauce recipe that is both simple to make and adds a lovely textured sauce to steamed vegetables such as cabbage has only made me love steamed vegetables even more!

Steaming vegetables is a great way to retain their vitamin content.

My absolute favourite accompaniment to onion sauce

The real turning point in my love of this onion sauce recipe? Poured over vegetarian haggis.

I’m totally serious.

For my New Year meal or on Burn’s Day, while those around me choose the traditional offal mixture for their haggis treat, I have vegetarian haggis. And trust me on this – everyone wants my vegetarian version with my onion sauce in preference to their own meat version with gravy, after just one taste.

Guaranteed.

I don’t have a recipe for vegetarian haggis to share

To date I haven’t tried to make my own vegetarian haggis. One day I will.

Until then this is a link to a brand sold on Amazon. This one is tinned so it keeps for 2 years until you’re ready to cook it.

The health and nutrition bit

Onions are rich in antioxidants that will help detoxify the liver and heal the gut wall.

Onions contain natural sugar, minerals such as sodium to help balance fluids in your body, potassium that supports blood pressure, cardiovascular health and bone & muscle strength, iron for energy and focus, and dietary fibre needed for your gut health.

The recipe

Onion sauce recipe
Yield: Serves 6

Savoury White Onion Sauce

Prep Time: 10 minutes
Cook Time: 35 minutes
Total Time: 45 minutes

Finding a recipe for onion sauce that catered for a cows milk allergy took some time and many failed attempts to get the taste right.

I settled on this one as it works really well with goats milk, or you could you use cashew milk to make it vegan. Cashew milk doesn't taste of nuts and the consistency is very similar to milk.

I did remove grain mustard from the original recipe. This version uses powdered English mustard and using two kinds just made it taste of vinegar.

For the butter, use goats milk butter or vegan butter if you want a vegan version of this recipe.

Ingredients

  • 1 large onion peeled and chopped
  • 40g/1.41 oz/2 tbsp of butter cut into cubes
  • 25g/1 oz/1/8 of a cup plain (or sauce) flour
  • 1 heaped tsp English mustard powder
  • 175ml/0.75 cup of milk of your choice
  • 175ml/0.75 cup of vegetable stock
  • Salt and freshly ground black pepper to season

Instructions

  1. Melt the butter in a saucepan
  2. Add the onion and stir well to make sure the onion is coated with butter
  3. Leave the onion to cook on a low heat for 20-25 minutes
  4. Stir occasionally so that the onion doesn't colour. You're aiming for translucent, cooked onion
  5. Meanwhile, prepare your stock
  6. Using a wooden spoon stir in the flour and the mustard powder and mix them together well
  7. Begin to add the milk a little at a time to make sure the sauce is smooth
  8. Turn up the heat to medium and gradually add the stock, stirring until all the stock has been added
  9. Turn the heat down to a simmer and leave to cook for 5 minutes to make sure the flavours blend together nicely
  10. Season to taste and serve

Health Benefits of Onion Sauce

Onions are rich in antioxidants that will help detoxify the liver and heal the gut wall.

Your finished onion sauce should be chunky but not crunchy

The finished onion sauce should have a nice 'bite' to it but shouldn't be crunchy. If it is crunchy it probably means you didn't cook the onions for long enough at step 3.

They really do need the full 20-25 minutes!
