Beef Dip Sauce Recipe: Rich Au Jus for Sandwich Dipping

This rich beef dip sauce transforms any sandwich into a gourmet experience with its deep, savory flavor. I developed this recipe to capture the essence of classic au jus without the fuss.

With just a few pantry staples and 20 minutes, you’ll have a versatile sauce perfect for dipping, pouring, or enhancing any meat dish. Store it in the fridge for up to a week.

Ingredients for Beef Dip Sauce

Nine ingredients. Twenty minutes. Rich, savory sauce ready for dipping anything.

The beef broth is the base here. Low-sodium is key so you can control the salt level—Swanson or Kitchen Basics are solid grocery store options. The Worcestershire is non-negotiable for that classic au jus depth (just check it doesn’t contain anchovies if that’s a concern). I grab mine from Trader Joe’s when I’m restocking. Fresh garlic and onion make all the difference, but jarred minced works in a pinch.

No Worcestershire? Extra soy sauce with a dash of fish sauce gets you close. Out of Dijon? Regular mustard works, but add a pinch of turmeric for color. The cornstarch can be swapped for arrowroot if you’ve got it. Butter is for richness, but olive oil does the job if you’re avoiding dairy. The onion can be powdered at one-third the amount in a real time crunch.

This keeps 1 week in the fridge, or freeze for 3 months (portion into ice cube trays for easy use). The flavor deepens overnight, so make it ahead if possible. Reheat gently—don’t let it boil or it’ll lose that silky texture.

Step-by-Step Instructions for Beef Dip Sauce

This method delivers a deeply flavorful au jus that’s perfect for sandwich dipping.

Step 1: Sauté the Aromatics

Melt 2 tbsp Butter in a saucepan over medium heat. Add the finely diced 0.5 whole Onion and cook for 4-5 minutes until translucent and just beginning to caramelize.

Stir in the minced 4 cloves Garlic Cloves and cook for an additional 30 seconds until fragrant. Watch carefully—garlic burns quickly and will turn bitter if left too long. The onion should be soft and golden, not browned.

Step 2: Build the Flavor Base

Pour in the 0.25 cup Soy Sauce, 2 tbsp Worcestershire Sauce, and 1 tbsp Dijon Mustard. Stir well to combine, scraping up any browned bits from the bottom of the pan. These bits contain concentrated flavor that will deepen your sauce.

Let the mixture simmer for 2 minutes, allowing the flavors to meld. You’ll notice the aroma becomes richer and more complex as the ingredients marry. The soy sauce provides saltiness and umami, while the Worcestershire adds its signature tangy depth.

Step 3: Add Broth and Simmer

Carefully pour in the 4 cups Beef Broth and add 0.5 tsp Black Pepper. Bring to a gentle boil, then reduce heat to maintain a steady simmer. This process should take about 5 minutes to reach the right temperature.

Simmer uncovered for 10-12 minutes, allowing the liquid to reduce slightly and concentrate the flavors. The sauce should develop a deeper color and more pronounced aroma as it cooks down.

Step 4: Thicken and Finish

In a small bowl, mix 1 tbsp Cornstarch with 2 tbsp of the hot broth from the saucepan to create a slurry. Stir until completely smooth with no lumps.

Slowly pour the slurry back into the saucepan while stirring constantly. Cook for an additional 2-3 minutes until the sauce thickens enough to lightly coat the back of a spoon. It should have a velvety texture, not too thin or overly thick. Taste and adjust seasoning if needed, though the soy and Worcestershire typically provide sufficient saltiness.

Dietary Considerations for This Recipe

Gluten-Free Options

This sauce can easily be made gluten-free by swapping the soy sauce for tamari. I use San-J Tamari which is certified gluten-free. Also verify your Worcestershire sauce—Annie’s makes a gluten-free version that works perfectly in this recipe. 💡

Dairy-Free Adaptation

Replace the butter with 2 tbsp olive oil or vegan butter. The flavor profile changes slightly but still delivers that rich mouthfeel. I’ve had great results with Miyoko’s plant-based butter.

Low-Sodium Version

Use low-sodium beef broth and reduce soy sauce to 2 tbsp. Compensate with 1 tsp fish sauce for umami. The Worcestershire already contains salt, so taste before adding any extra seasoning.

Vegan Modification

Substitute beef broth with mushroom or vegetable broth. Add 1 tbsp nutritional yeast for depth. The Worcestershire is the tricky part—Edward & Sons makes a vegan version that works well here.

Allergen Notes

This recipe contains no nuts, eggs, or shellfish. The main allergens to watch are soy (in soy sauce) and dairy (in butter). Always check labels on your Worcestershire sauce as some contain anchovies. 🌱

Keto-Friendly

This sauce is naturally keto-friendly as written. The cornstarch adds minimal carbs (7g per tbsp). For strict keto, omit it entirely—the sauce will be thinner but still flavorful. Or use xanthan gum as a thickener instead.
