Step 1: Gather Your Ingredients

To make a delicious au jus, you’ll need the following ingredients:

– Beef stock or beef broth (32 ounces)

– Onion (1 medium-sized, thinly sliced)

– Garlic (2 cloves, minced)

– Worcestershire sauce (2 teaspoons)

– Soy sauce (1 tablespoon)

– Fresh thyme (2 sprigs) or dried thyme (1/2 teaspoon)

– Black pepper (1/4 teaspoon, freshly ground)

– Optional: Dry red wine (1/2 cup)

Step 2: Prepare a Roasting Pan

If you are using the drippings from roast beef, make sure your roasting pan is reserved with the juices. The combination of roast beef drippings and other ingredients will give your au jus that authentic flavor.

Step 3: Sauté the Onion and Garlic

In a medium saucepan, heat one tablespoon of olive oil or butter over medium heat. Add the thinly sliced onions and cook for about five minutes until they are soft and golden brown. Then, add the garlic and cook for another one minute.

Step 4: Deglaze Your Saucepan

If you are using red wine in your au jus recipe, add it at this stage. Pour the wine into the saucepan and use a wooden spoon or spatula to scrape up any browned bits from the bottom. Cook for two to three minutes until slightly reduced.

Step 5: Combine Ingredients

Add in your beef stock or broth to your saucepan. Stir in Worcestershire sauce, soy sauce, fresh thyme (or dried thyme), and black pepper. If you have roast beef drippings from step 2, skim off any fat and add them to the mixture.

Step 6: Simmer the Au Jus

Bring your mixture to a boil, then reduce the heat to low and allow it to simmer for about 20-30 minutes. Stir occasionally during this process to ensure all flavors are melding together.

Step 7: Taste and Adjust

As your au jus simmers, taste it periodically to check the seasoning. Adjust as needed by adding more salt, pepper, or Worcestershire sauce to suit your preferences.

Step 8: Strain Your Au Jus

After the simmering time has passed, strain your au jus through a fine mesh sieve or cheesecloth into a serving bowl or gravy boat. This will remove any solids such as onions, garlic, and thyme sprigs, leaving you with a smooth and flavorful sauce.

Step 9: Serve Your Au Jus

Your delicious au jus is now ready to serve! Pour it over roast beef or use it as a dipping sauce for sandwiches like a classic French Dip. Enjoy!
