Au Jus Recipe

Introduction

Au jus, French for “with juice,” is a savory and flavorful sauce made from the natural juices released during the cooking of meat. Its popularity stems from its rich, concentrated flavor that elevates a variety of dishes, particularly roast beef, French dip sandwiches, and prime rib. Unlike gravy, au jus is typically thinner and lighter, relying primarily on the essence of the meat itself for its distinctive taste. Preparing au jus from scratch allows for complete control over the ingredients and intensity of flavor, making it a rewarding endeavor for home cooks.

Ingredients

The foundation of any good au jus recipe lies in quality ingredients. The essential components include:

Beef Roast: The drippings from the roast are the heart of the au jus. Choose a roast appropriate for your main course.
Beef Broth: Use a high-quality beef broth or stock to supplement the natural juices. Low-sodium options are recommended to control the salt level.
Aromatics: Onions, carrots, and celery (mirepoix) provide a depth of flavor. Garlic adds a pungent note.
Herbs: Fresh thyme and rosemary contribute earthy and aromatic complexity. Dried herbs can be used in a pinch.
Red Wine (Optional): A dry red wine, such as Cabernet Sauvignon or Merlot, can add richness and acidity.
Worcestershire Sauce: A small amount enhances the umami flavor.
Bay Leaf: Adds a subtle, savory aroma.
Black Peppercorns: Freshly cracked peppercorns provide a spicy kick.
Salt: To taste, added judiciously.

Possible Substitutions:

Chicken or vegetable broth can be used if beef broth is unavailable, but the flavor will be different.
Shallots can be substituted for onions for a more delicate flavor.
Dried thyme and rosemary can be used in place of fresh herbs, using about 1 teaspoon of each for every tablespoon of fresh.

Preparation Steps

Proper preparation is key to a flavorful au jus. Start by thoroughly rinsing and patting dry the beef roast. Season generously with salt, pepper, and any other desired spices or rubs. While the roast is cooking, prepare the vegetables. Roughly chop the onions, carrots, and celery. Mince the garlic. If using fresh herbs, tie them together with kitchen twine for easy removal later. These initial steps ensure that all ingredients are ready to contribute their flavors at the appropriate time. Tossing the vegetables with a little oil and salt before adding to the roasting pan can enhance their caramelization during the cooking process, leading to a richer, deeper flavor in the au jus.

Cooking Instructions

The cooking process begins concurrently with roasting the beef.

Roast the Beef: Follow your chosen recipe for roasting the beef. Crucially, use a roasting pan that allows the drippings to collect at the bottom.
Remove the Roast: Once the beef is cooked to your desired internal temperature, remove it from the roasting pan and let it rest, covered loosely with foil, for at least 15-20 minutes. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful roast.
Deglaze the Pan: While the roast rests, place the roasting pan over medium heat on the stovetop. Add the chopped vegetables and cook, stirring occasionally, until softened and slightly browned (about 5-7 minutes). This step builds a flavorful base for the au jus.
Add Wine (Optional): If using red wine, pour it into the pan and scrape up any browned bits from the bottom (fond). Allow the wine to reduce slightly, about 2-3 minutes.
Add Broth and Aromatics: Pour in the beef broth, Worcestershire sauce, bay leaf, and peppercorns. Bring to a simmer.
Simmer and Reduce: Reduce the heat to low and simmer the au jus for at least 30 minutes, or up to an hour, allowing the flavors to meld and the liquid to reduce. The longer it simmers, the more concentrated the flavor will become. Skim off any excess fat that rises to the surface.
Strain and Season: Strain the au jus through a fine-mesh sieve, discarding the solids. Taste and adjust seasoning with salt and pepper as needed. If the au jus is too thin, it can be thickened slightly with a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water). Gradually whisk the slurry into the simmering au jus until it reaches the desired consistency.

Recommended Times and Temperatures:

Simmer time: 30-60 minutes, low heat
Roast beef cooking time varies greatly depending on the size and desired doneness. Refer to a reliable roast beef recipe for specific guidelines.

Serving Suggestions

Au jus is traditionally served alongside roast beef, providing a moist and flavorful complement. It is also a key component of the classic French dip sandwich. Some serving suggestions include:

French Dip Sandwiches: Thinly sliced roast beef piled high on a crusty baguette, served with a side of au jus for dipping.
Prime Rib: A classic pairing. Serve the au jus in a small gravy boat or ramekin alongside slices of prime rib.
Beef Tenderloin: Drizzle au jus over sliced beef tenderloin for added moisture and flavor.
Mashed Potatoes: A spoonful of au jus elevates simple mashed potatoes.
Yorkshire Pudding: Serve Yorkshire pudding with a generous drizzle of au jus.

Traditional accompaniments include horseradish sauce, creamy horseradish sauce, and crusty bread for soaking up the delicious juices.

Tips and Common Mistakes

To ensure a successful au jus, keep these tips in mind:

Don’t skip the resting period for the roast beef. This is crucial for retaining juices and creating flavorful drippings.
Use a good quality beef broth. The broth will heavily influence the final flavor of the au jus.
Don’t over-salt. Start with a small amount of salt and add more to taste after simmering.
Skim off excess fat. This will result in a cleaner, more flavorful au jus.
Be patient. Allowing the au jus to simmer for a longer period will result in a more concentrated flavor.

Common Mistakes to Avoid:

Using too much salt.
Not skimming off fat, which makes it greasy.
Skipping the deglazing step, as the fond is vital for flavor.
Not straining the sauce, which leaves it lumpy and inconsistent.
