Ingredients for mustard sauce for steak labeled on counter.

Ingredients needed

  • Butter
  • Shallot
  • Cognac – A splash of cognac, brandy, or bourbon adds a sophisticated and complex flavor profile to the steak sauce. Don’t worry—most, if not all, of the alcohol is cooked out!
  • Heavy cream – This gives your sauce the most luxurious and silky consistency. You can use whole milk as a substitute, but the sauce won’t be as rich.
  • Honey – A little sweetness helps balance the pungent and tangy mustard. Feel free to use maple syrup if that’s what you have on hand.
  • Mustard – I like whole grain mustard in my steak mustard sauce because of the added texture and robust flavor; however, almost any kind of mustard works well. Make it with Dijon mustard or spicy brown mustard for a smooth texture and a bold, slightly spicy flavor, or use yellow mustard if you prefer a mild flavor. 
  • Parsley 
  • Salt and black pepper

How to make creamy mustard sauce for steak

If you’re pan searing steak, remember to save the pan juices because they add even more flavor and dimension to the mustard sauce. 

Start the sauce by melting the butter in the skillet you used to cook the steaks. Once melted, add the shallots and sauté until softened. 

Pour the cognac into the skillet and cook until it has reduced by half.

Add the heavy cream and honey, then simmer until the liquids reduce.

Remove the skillet from the heat and whisk in the mustard, parsley, salt, and pepper. Serve your cooked steak with mustard sauce on top or on the side and enjoy!

Tips and tricks

  • A whisk is your best friend when making steak sauces. By whisking each ingredient into the skillet, you avoid lumps, help emulsify the sauce, and yield a smooth, velvety consistency. 
  • Always taste the sauce before serving. You can add more honey for sweetness, mustard for tang, or salt and pepper to round out the rest of the flavors.
  • Also, mustard can be a bit salty, so be mindful when adding extra salt.

Variations

Customize the flavor to your liking using any of these variation ideas:

  • Mix and match the mustard – Try combining Dijon with whole grain or spicy brown mustard for a more complex flavor profile.
  • Experiment with aromatics and fresh herbs – Sauté minced garlic cloves alongside the shallots. For an herbaceous taste, add finely chopped herbs to the sauce, like chives or tarragon.
  • Give it a kick – Add smoked paprika for a subtle smokiness or some horseradish for a bold, spicy kick. 
  • Instead of cognac – Brandy and bourbon are the best substitutes for cognac, or you can use a splash of dry white wine.
  • Alcohol free – If you’d rather make mustard sauce without alcohol, replace the cognac with low-sodium chicken stock, mushroom stock, or balsamic vinegar.  

Serving suggestions

Creamy mustard sauce is, obviously, a steak’s best friend. I like it best with naturally juicy, tender, and flavorful cuts, like ribeye, filet mignon, sirloin, or New York strip.

Beyond steak, its tangy and creamy flavors also complement grilled chicken, ham steak, pork chops, and smoked burgers perfectly as well. It’s even great with vegetables! Serve it next to sweet potatoes, broccoli, or brussels sprouts for a delicious dipping sauce.

Storing

Store the leftover mustard sauce in an airtight container and refrigerate for 3 to 5 days. 

Technically, you can freeze the leftover sauce, but I don’t recommend it. As it thaws, the cream may become gritty, which will ruin the sauce’s velvety and creamy consistency.
