Steak Pan Juices for Mushroom Sauce
For the best mushroom sauce for steak, start with the steak pan juices after cooking the steak. This is our little secret to a rich, flavourful base.
But you can absolutely build up a great mushroom cream sauce without them if needed, which is why it is not included on the ingredients list.
Instructions
Whether you are a beginner or a professional chef, these simple steps will help you master this mushroom sauce and impress everyone at the dinner table.
Prepare
Before you start, have all your equipment and ingredients measured and ready.
Clean any dirt off your mushrooms with a damp kitchen towel to avoid waterlogging them.
Chop all the ingredients before cooking the steak so you can make the sauce quickly whilst the steak rests.
If you've cooked steak, save those pan juices! They're gold for flavour.
Cook
Melt your butter in a pan on medium-high heat. Sautรฉ the mushrooms for about 5 minutes before adding the garlic and onions for another 10 minutes.
Time for the thyme! Strip the leaves from thyme sprigs and sprinkle them in.
Merge the beef stock and Dijon mustard into the mix with a good old stir, seasoning it with salt and freshly ground black pepper.
Thicken Mushroom Sauce
In a separate bowl, blend cornstarch with a tablespoon of water until smooth and stir this into your pan.
Bring to the boil, then lower the heat. If you are not using cream or making it ahead to freeze, you can end the cooking process here.
Or continue making the creamy sauce by adding in the double cream.
Stirring until warm, avoid boiling with the cream.
Serving Suggestions
Use it to add a rich sauce to many dishes, such as grilled steak, roasted chicken, pork chops, or even vegetarian alternatives like mashed potatoes - mashed potato recipe.
