What Makes Easy Prime Rib Au Jus Sauce So Good?

A good au jus should taste deeply meaty, balanced, and light enough to pour over beef without feeling heavy. Unlike thick gravy, au jus is thinner and more refined, which makes it ideal for prime rib. It highlights the roast instead of covering it up.

This Easy Prime Rib Au Jus Sauce works because it uses the flavorful drippings from the roast whenever possible, then builds on them with beef broth, Worcestershire sauce, garlic, and a little black pepper. The result is a glossy sauce with bold flavor and just the right amount of richness.

Ingredients for the Easy Prime Rib Au Jus Sauce

The beauty of this sauce is that every ingredient has a job to do. Together, they create a classic beefy sauce that is simple, elegant, and easy to adjust to your taste.

Main Ingredients

• 2 cups beef drippings and broth combined: Use the drippings from your prime rib first, then add beef broth as needed to reach the full amount.
• 2 cups beef broth: Gives the sauce extra body and ensures you have enough liquid, especially if your roast did not produce many drippings.
• 1 tablespoon Worcestershire sauce: Adds savory depth and a subtle tangy note.
• 1 teaspoon garlic powder: Brings mellow garlic flavor without changing the smooth texture.
• 1/2 teaspoon onion powder: Adds background savoriness and rounds out the sauce.
• 1/2 teaspoon black pepper: Gives the au jus gentle warmth.
• 1/2 teaspoon kosher salt: Adjust to taste, especially if your broth is already salted.
• 1 tablespoon unsalted butter: Optional, but helpful for a silkier finish.

Optional Add-Ins

• 1 teaspoon fresh thyme leaves: Lovely for a more herb-forward holiday flavor.
• 1 teaspoon soy sauce: A small splash can deepen the color and umami.
• 1 teaspoon cornstarch mixed with 1 tablespoon cold water: Only if you want the sauce slightly thicker than traditional au jus.

How To Make the Easy Prime Rib Au Jus Sauce

This sauce comes together quickly, especially if you make it while the prime rib is resting. That timing gives you a chance to collect the drippings and build the sauce while the roast stays juicy.

Step 1: Collect the drippings

Carefully pour the pan drippings from the roasting pan into a measuring cup. Let the fat rise to the top, then skim off excess fat if desired. Keep the flavorful brown juices underneath. Add enough beef broth to the drippings to make 2 cups total.

Step 2: Build the sauce base

Pour the drippings mixture and the additional 2 cups beef broth into a medium saucepan. Whisk in the Worcestershire sauce, garlic powder, onion powder, black pepper, and salt.

Step 3: Simmer for deeper flavor

Place the saucepan over medium heat and bring the mixture to a gentle simmer. Let it cook for 8 to 10 minutes, stirring occasionally, so the flavors meld and the sauce reduces slightly.

Step 4: Adjust the texture

If you want a classic au jus, keep it thin and pourable. If you prefer it just a bit richer, whisk in the cornstarch slurry and simmer for 1 to 2 more minutes until lightly thickened.

Step 5: Finish with butter

Turn off the heat and whisk in the butter until melted. This step gives the sauce a smooth, glossy finish and a slightly richer taste.

Step 6: Strain and serve

For the smoothest texture, strain the sauce through a fine mesh sieve before serving. Pour it over sliced prime rib or serve it on the side for dipping.

Serving and Storing Easy Prime Rib Au Jus Sauce

This sauce is at its best served warm right after your roast is sliced. Spoon it over prime rib, use it as a dipping sauce for French dip style sandwiches, or drizzle it over mashed potatoes, roasted carrots, or Yorkshire pudding.

If you have leftovers, let the sauce cool completely and store it in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stove over low heat, stirring often. If the sauce separates slightly after chilling, whisking it as it warms will bring it back together.

For longer storage, freeze it in a small freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I make Easy Prime Rib Au Jus Sauce without drippings?

Yes. You can make it with all beef broth if needed. The sauce will still taste good, though the flavor will be even better with roast drippings.

Is au jus the same as gravy?

Not quite. Au jus is usually thinner and lighter, while gravy is thicker and often made with more flour or cornstarch.

Can I make this ahead of time?

Yes. You can prepare it a day in advance, refrigerate it, and gently reheat before serving.

What can I serve with this besides prime rib?

It is also delicious with roast beef sandwiches, steak, mashed potatoes, or even over roasted vegetables.

How do I keep it from getting too salty?

Start with low-sodium beef broth if possible, and wait until the end to adjust the salt. Pan drippings can already be quite seasoned.

Can I add red wine to the sauce?

Yes. Replace about 1/2 cup of broth with red wine and simmer a little longer for a deeper, more robust flavor.
