Sauces & Condiments
This au jus sauce recipe with beef broth transforms simple ingredients into a deeply umami-rich sauce that elevates any beef dish. The secret lies in building flavor through a homemade fond—a rich, caramelized residue from seared beef—that forms the backbone of this sauce.
I developed this recipe after years of experimenting with how to capture that restaurant-quality depth at home, and it never fails to impress.
The process starts with searing beef bones or chunks to create that flavorful fond, which you then deglaze with beef broth and aromatics like garlic and shallots. Simmering reduces the liquid into a concentrated, velvety sauce with just the right balance of richness and acidity.
A touch of cornstarch or a light roux ensures the perfect consistency—smooth enough to coat, but still bright enough to complement rather than overpower.
What you'll end up with is a sauce that's restaurant-quality—glossy, deeply savory, and packed with layers of flavor. It's the kind of sauce that makes roasted beef, meatloaf, or even simple steak feel like a special occasion.
The beauty of this recipe is that it's built on simple techniques but delivers professional results every time.
Use it to drizzle over your favorite beef dishes, or keep a jar in the fridge for quick flavor boosts. The sauce keeps well for up to a week, making it perfect for meal prep or entertaining. Here's how to make it—step by step.
Ingredients for au jus sauce recipe with beef broth
Nine ingredients, one restaurant-quality sauce. Nothing fancy, just deep umami magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Bones or Chunks 🍖 | 2 lb | For making fond, marrow bones ideal |
| Beef Broth 💧 | 4 cups | Homemade or high-quality store-bought |
| Shallots 🧅 | 3 whole | Minced for aromatic base |
| Garlic Cloves 🧄 | 6 cloves | Smashed for deeper flavor |
| Red Wine 🍷 | 1 cup | Dry red like Cabernet Sauvignon |
| Tomato Paste 🍅 | 2 tbsp | For umami depth |
| Cornstarch 🌾 | 1 tbsp | For thickening slurry |
| Cold Water 💧 | 1 tbsp | For cornstarch slurry |
| Black Peppercorns 🌶️ | 10 whole | Crushed for peppery bite |
| Fresh Thyme 🌿 | 2 sprigs | For herbal brightness |
The beef is where the magic starts. Marrow bones give the richest fond, but any beef with good marrow works—even just chunks of chuck or short ribs. Costco or butcher shops are your best bet for bones. Look for ones with visible marrow—it's that creamy stuff inside the bone, and it's pure flavor gold. If you're using store-bought beef broth, Swanson or Pacific Foods are solid choices, but homemade is always better. The shallots and garlic? Fresh is non-negotiable here—they're the aromatic backbone of the sauce. I always buy extra garlic because it's used in so many things.
No red wine? Substitute with extra beef broth and a splash of balsamic vinegar—it adds that tangy depth. Running out of thyme? Fresh rosemary works too, but use half as much since it's stronger. The tomato paste can be skipped if you're avoiding acidity, but I always include it—it adds that umami punch without overpowering. For the cornstarch slurry, make sure it's fully dissolved in cold water before adding to the sauce. Diamond Crystal kosher salt is my go-to for seasoning, but any fine sea salt works. And if you're feeling fancy, a pinch of white pepper adds a nice contrast to the black peppercorns.
This sauce tastes even better the next day as flavors meld. Store it in an airtight jar in the fridge for up to 5-7 days. For longer storage, freeze in ice cube trays—just thaw what you need. I always make a double batch because it disappears fast. The fond-making process is the key—don't rush it. Let those bones sear until they're deep brown and the fond is rich and sticky. That's where 90% of the flavor comes from. And if you're making it ahead, the sauce can actually improve overnight—just give it a quick stir before serving.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this—just toss in bones, broth, and aromatics, then let it simmer. No straining, no fussing, just richness in a single pot. The shallots caramelize right in the broth, adding depth without extra work.
- Wine-Infused Depth: That splash of red wine? It’s not just flavor—it’s transformation. The acidity cuts through the richness, while the alcohol cooks off to leave behind layers of umami and warmth. Honestly, it’s the kind of sauce that makes you pause mid-bite.
- Leftovers That Shine: Make a big batch—this stuff only gets better as it sits. I’ll freeze half for roasts or steaks later, and the rest? Drizzled over mashed potatoes or egg noodles. It’s my go-to for turning simple meals into feasts with zero extra effort.
- Budget-Friendly Luxury: Beef bones and broth stretch this sauce far, but it still tastes like a restaurant’s au jus. Between us, I’ve used cheaper cuts of beef and still ended up with a sauce so good, no one complains. It’s the kind of recipe that makes frugality feel indulgent.
Step-by-step instructions for rich beef au jus
This isn't your basic pan drippings—we're making a velvety, umami-packed au jus from scratch.
Make the Fond from Beef Bones
Place the 2 lb beef bones or chunks in a heavy-bottomed pot and add the 4 cups beef broth. Bring to a boil over medium-high heat, then immediately reduce to a simmer. Let it cook uncovered for 45-60 minutes, skimming off any foam or impurities that rise to the surface with a fine-mesh skimmer.
You'll see golden brown bits settle at the bottom—this is the fond, packed with flavor. After simmering, strain the broth through a fine-mesh sieve into a clean pot, discarding the bones. The fond will remain in your sieve—don't throw it away! We'll use it to build our sauce's depth.
Build the Flavor Base
Return the strained broth to the pot and add the minced 3 whole shallots, smashed 6 cloves garlic, crushed 10 whole black peppercorns, and 2 sprigs fresh thyme. Bring to a gentle boil, then reduce heat to medium-low and let it simmer uncovered for 10-12 minutes until the aromatics are completely tender and the liquid has reduced by about ¼.
Here's where the magic happens—let the flavors meld. You should smell that deep, savory aroma developing. If you notice any scum forming, skim it off immediately. The broth should now be concentrated and aromatic, ready for the next layer of flavor.
Add Wine and Tomato Paste
Remove the pot from heat and stir in the 1 cup red wine and 2 tbsp tomato paste. Return to medium heat and let it simmer for 5-7 minutes, stirring occasionally, until the wine has completely evaporated and the tomato paste has dissolved into the broth.
This step develops the sauce's complexity. The wine adds acidity to balance the richness, while the tomato paste contributes umami depth. You'll notice the sauce darkening slightly as it reduces—this is normal and desirable. Keep an eye on it to prevent burning.
Thicken the Au Jus
In a small bowl, whisk together the 1 tbsp cornstarch and 1 tbsp cold water until completely dissolved. Slowly pour this slurry into the simmering sauce while stirring constantly with a wooden spoon. Return to medium heat and let it simmer for 3-5 minutes until the sauce has thickened to your desired consistency.
The sauce should coat the back of a spoon but still be pourable. If it thickens too much, you can thin it with a splash of warm water. Taste and adjust seasoning with additional salt if needed—this homemade au jus should be rich but balanced, with bright herbal notes from the thyme and pepper.
Finish and Serve
Remove the pot from heat and let the sauce rest for 5 minutes to allow the flavors to fully meld. Strain the au jus through a fine-mesh sieve into a clean saucepan to remove any thyme stems or other solids. The sauce should now be smooth, glossy, and deeply flavorful.
Serve immediately over sliced beef, roasted potatoes, or crusty bread. This au jus keeps well in the refrigerator for up to 5 days and can be reheated gently on the stove. The longer it sits, the more the flavors develop—trust me, it only gets better!
Pro Tips For Making Au Jus Sauce Recipe With Beef Broth
- Brown the Bones First: Skip the direct broth dump—sear your beef bones or chunks in a hot pot until deep golden. The Maillard reaction pulls flavor from the meat into the sauce, and you’ll taste the difference when you add the broth later. (Yes, even if you’re impatient like me.)
- Sweat, Don’t Sear, the Aromatics: Shallots and garlic need gentle love here. Cook them low and slow in oil until soft and translucent—no rushing, no burning. If they brown too fast, you’ll end up with bitter bits instead of sweet, mellow depth in your au jus.
- Deglaze with a Splash: After searing the bones, add just enough red wine to barely cover the fond at the bottom. Let it bubble for 30 seconds, then scrape with a wooden spoon—this grabs all the stuck-on flavor before you add the broth. (Your future self will notice the richer taste.)
- Simmer, Don’t Boil: Once the broth is in, keep the heat at a gentle simmer—tiny bubbles, not a rolling boil. High heat breaks down collagen too fast, making the sauce thin and watery. Low and slow is the only way to get that silky, velvety texture. (I learned this the hard way with a sad, watery pot.)
Perfect pairings for this recipe
Beef Dish Pairings
This au jus sauce is a game-changer for roasted beef tenderloin—its rich depth cuts through the natural richness of the meat. I like to serve it with a crispy skin on the outside and medium-rare center, then drizzle the sauce generously over sliced portions.
For a complete meal, pair with garlic mashed potatoes—the buttery creaminess balances the sauce's acidity perfectly. 🥔
Vegetable Sides
Roasted root vegetables add earthy contrast to the sauce's brightness. Try carrots and parsnips tossed in olive oil, honey, and thyme, then roasted until caramelized. Another winner is creamy polenta with a sprinkle of Parmesan—it soaks up the sauce beautifully.
For something lighter, a simple arugula salad with lemon vinaigrette keeps the meal balanced.
Bread Service
No beef dinner is complete without bread to mop up the sauce. I recommend a crusty baguette sliced into thick pieces and toasted with garlic butter. For something more substantial, serve with cheesy breadsticks—the melted cheese adds another layer of comfort.
Even a simple sourdough loaf works if you're keeping it minimal.
Wine Pairings
A bold red wine complements this sauce beautifully. I love pairing it with a Cabernet Sauvignon from Napa Valley—the tannins stand up to the sauce's richness.
For something lighter, a Pinot Noir from Oregon provides bright acidity that cuts through the fat. Avoid heavy, oaky whites—they'll clash with the sauce's depth.
Cheese Course
If you're serving this as part of a multi-course meal, finish with a simple cheese board featuring aged cheddar, Gruyère, and blue cheese. The sharp, tangy notes of blue cheese actually enhance the umami flavors in the sauce. Serve with crackers or sliced baguette for easy pairing.
Make-Ahead Tips
This sauce actually improves overnight, so make it a day ahead for even deeper flavor. Store in an airtight container in the fridge, then reheat gently on the stove before serving.
For parties, freeze the sauce in ice cube trays**—thaw just what you need and keep the rest frozen. The sauce reheats beautifully, making it perfect for meal prep. 💫

Frequently asked questions
Can I make this au jus sauce without wine?
Replace the 1 cup red wine with 1 cup beef broth plus 1 tablespoon balsamic vinegar for acidity. The sauce will still develop rich depth, though the wine adds a subtle complexity that's hard to replicate. For a non-alcoholic version, use 1 cup beef broth and 1 teaspoon lemon juice instead.
How do I know when the fond is ready?
The fond is ready when the beef bones are deep golden brown and the liquid has reduced to a rich, sticky residue at the bottom of the pot. This usually takes 45-60 minutes of simmering. The fond should look almost caramelized—like a thin, glossy layer—before you strain the broth. Don't rush this step; patience here makes all the difference in flavor.
Can I use chicken or vegetable broth instead of beef broth?
For an authentic beef au jus, stick with beef broth—the umami depth is essential. However, you can use chicken broth for a lighter version (great with pork or chicken dishes) or vegetable broth for a vegetarian adaptation. Just add 1 teaspoon soy sauce or mushroom powder to boost umami if using vegetable broth.
Why did my sauce turn cloudy or separate?
Cloudiness often happens if the cornstarch slurry wasn't fully dissolved before adding or if the sauce boiled too vigorously. To fix it, whisk in 1 teaspoon cold water and ½ teaspoon cornstarch, then simmer gently for 2-3 minutes. For separation, strain the sauce again through a fine-mesh sieve and reheat slowly while stirring constantly. The sauce should be silky smooth when properly reduced.
How can I make this sauce spicier?
Add ½ teaspoon smoked paprika or ¼ teaspoon cayenne pepper during the final simmer. For heat with depth, stir in 1 teaspoon harissa paste or a pinch of crushed red pepper flakes.
