Step 1

Crumble stock cubes into a heat-proof jug and add the boiling water. Stir until stock cubes have dissolved.

Step 2

Heat the butter in a pan over a medium-high heat until melted. Add the flour and onion powder, and stir to combine with the butter to form a paste.

Step 3

Allow it to cook for a few minutes (you can actually allow it to brown a little at this stage if you like brown gravy). [Note 2]

Step 4

Slowly start to add the stock around ¼ cup at a time. Mix it in well each time you add some, and allow the gravy to thicken before adding more. You can whisk the gravy to make it really smooth.

Step 5

Once all the liquid has been added, continue heating and stirring for around 2 minutes while the gravy thickens.

Step 6

Season to taste with salt and pepper.

Step 7

Serve hot.
