Au Jus Recipe With Beef Consommé: Rich Umami Depth From Homemade Broth

This au jus recipe with beef consommé transforms simple ingredients into a restaurant-quality sauce with deep umami richness. The foundation lies in homemade consommé—clarified, aromatic, and packed with beef flavor—reduced to a velvety, concentrated liquid that clings to every bite.

It’s the kind of sauce that elevates roasted beef, steak sandwiches, or even a classic Reuben, turning ordinary meals into something extraordinary.

The process begins with slow reduction of consommé, where shallots, peppercorns, and bay leaf infuse layers of savory complexity. A light cornstarch slurry thickens the sauce just enough to coat without heaviness, ensuring every spoonful delivers that signature clear, glossy finish that defines true au jus.

The key? Patience—letting the sauce simmer until it reaches the perfect balance of intensity and smoothness.

What you’ll end up with is a bold, golden-brown sauce that’s rich yet light, with a depth of flavor that comes only from homemade consommé. It’s the kind of sauce that makes you pause mid-bite, savoring the harmony of beef, aromatics, and umami.

No shortcuts here—this is the real deal, built from scratch for maximum flavor impact.

Perfect for drizzling over roasted prime rib, smothering steak fries, or even adding a touch of elegance to a classic beef sandwich. The versatility of this sauce makes it a staple in any kitchen—once you taste it, you’ll never go back to store-bought again.

Ingredients for au jus recipe with beef consomme

Homemade consommé and aromatic aromatics create this luxurious, umami-packed au jus worth every minute.

The consommé is non-negotiable here—homemade is essential for that restaurant-quality depth. Look for beef bones with good marbling at Whole Foods or your local butcher shop. If you're short on time, a high-quality beef stock from Kirkland Signature works in a pinch, but it won't have the same clarity. The shallots should be vibrant purple, not dried out. For the peppercorns, Tellicherry is ideal, but regular black peppercorns crushed in a mortar and pestle will do. Fresh bay leaves add a subtle floral note that dried can't match—grab a few extra since they're used whole and removed later.

No homemade consommé? High-quality beef stock (like Crest or Swanson) works, but reduce it by half before using. Running short on shallots? Yellow onion at double the amount gives similar sweetness. The cornstarch slurry needs to be smooth as silk—whisk it vigorously to avoid lumps. For the mustard, Dijon is a must—whole grain adds texture, but classic works too. Worcestershire can be swapped for soy sauce at half the amount if you're avoiding umami boosters. The butter should be cold when added—this creates those beautiful, glossy ribbons in the finished sauce.

This sauce peaks when freshly made, but it keeps beautifully in the fridge for 5-6 days in an airtight container. For longer storage, freeze in ice cube trays—thaw and reheat gently for perfect consistency. The sauce thickens as it cools, so add a splash of hot water when reheating if it seems too stiff. I always make extra—it freezes perfectly and elevates simple roast beef sandwiches to gourmet status. The key to reheating? Low heat only—you're not cooking it, just waking it up.

Step-by-step instructions for crafting au jus with beef consommé

Transform simple ingredients into a velvety, umami-rich au jus that elevates any beef dish.

In a medium saucepan, melt the 2 tablespoons unsalted butter over medium heat. Add the 0.5 cup finely minced shallots and cook for 4-5 minutes until they become translucent and just beginning to soften. This gentle cooking prevents bitterness and develops their sweetness.

Add the 1 tablespoon crushed black peppercorns and 2 whole bay leaves to the pan. Stir for 30 seconds to release their aromatic oils. Here's the thing—these spices will infuse the consommé with layers of complexity, but they won't dissolve completely. That's perfect; we want subtle depth, not overpowering spice. Keep the heat at medium throughout this step to avoid burning the shallots.

Pour in the 4 cups beef consommé and bring the mixture to a gentle simmer over medium-high heat. You'll see small bubbles form at the edges and hear a soft, steady hum—this is your signal that the liquid is hot enough. Let it simmer uncovered for 10 minutes to allow the flavors to meld and the liquid to reduce slightly.

During this time, add the 1 tablespoon Worcestershire sauce and 1 teaspoon Dijon mustard. Stir gently to combine. The Worcestershire adds that signature umami punch, while the Dijon mustard introduces a subtle tang that balances the richness. Taste the mixture now—you should detect the underlying beef flavor with hints of shallot sweetness and peppery warmth.

In a small bowl, whisk together the 1 tablespoon cornstarch and 0.25 cup cold water until completely dissolved. This creates a smooth slurry that will thicken your au jus without creating lumps. Slowly pour the slurry into the simmering pan while stirring constantly with a wooden spoon.

Continue stirring for 2-3 minutes until the au jus reaches your desired consistency—it should coat the back of a spoon but still be pourable. If it thickens too quickly, add 1-2 tablespoons hot consommé from the pan to adjust. The key here is patience; rushing the thickening process can create a gluey texture instead of the silky finish you want.

Remove the pan from heat and let it sit for 2 minutes to allow the cornstarch to fully set. Then, stir in the 0.5 teaspoon kosher salt and taste again. Adjust the seasoning if needed—this is where you fine-tune the balance between savory, salty, and slightly tangy notes. Remember, homemade consommé already carries significant depth, so you might find you need less salt than expected.

Strain the au jus through a fine-mesh sieve into a clean saucepan to remove any solids. Return it to low heat and keep it warm until ready to serve. The finished au jus should be glossy, with a velvety texture that clings beautifully to roasted beef or steak. Serve immediately alongside your main course for maximum impact.

Dietary considerations for this dish

Gluten-Free Adaptations

This au jus is naturally gluten-free if you use gluten-free Worcestershire sauce like Annie's or Bragg Liquid Aminos. The cornstarch thickening can be swapped for arrowroot powder (same ratio) or a roux made with butter and gluten-free flour blend like Bob's Red Mill 1:1.

Always check labels—some Worcestershire sauces contain wheat malt vinegar. 🌾

Low-Sodium Options

Homemade consommé already has less sodium than store-bought, but for extra control, reduce the ½ tsp kosher salt to ¼ tsp and add a pinch of smoked paprika for depth.

Use low-sodium beef stock if making consommé from scratch. Taste frequently—homemade consommé packs enough umami that you might not need added salt at all.

Vegetarian Substitutes

Replace the beef consommé with mushroom consommé (simmered with dried porcini and shallots) or vegetable consommé from Pacific Foods. Swap Worcestershire for soy sauce or liquid aminos.

The cornstarch slurry remains the same, but add 1 tsp balsamic vinegar to mimic the tangy depth of traditional au jus. 🌱

Dairy-Free Version

Skip the butter entirely and use olive oil for sautéing shallots. For richness, finish with 2 tbsp dairy-free butter like Miyoko's or Earth Balance. The cornstarch slurry stays the same, but add 1 tsp nutritional yeast to enhance the umami profile. The texture remains velvety, just without dairy.

Allergen-Friendly Notes

For nut allergies, avoid Worcestershire brands with soy sauce (some contain soy nuts). For egg allergies, ensure cornstarch is certified egg-free (Bob's Red Mill is safe). Always double-check labels—cross-contamination risks exist in shared facilities. When in doubt, make your own consommé from scratch for full control over ingredients.
