This 3 ingredient, creamy mustard sauce, is perfectly balanced and enhances the meat's natural flavor without overpowering it.
Mustard - The key to this recipe is using a good quality stone-ground mustard. This will give the sauce a nice grainy texture and depth of flavor.
Butter - I recommend using unsalted butter to control the amount of salt in the recipe. If you use salted butter, you may want to omit the pinch of salt at the end.
Cream - Use heavy whipping cream for a richer, creamier sauce.
Dijon Mustard - Whip up a nice creamy Dijon mustard sauce!
Without Cream - Try sour cream or Greek yogurt if you'd prefer a mustard sauce for steak without cream.

Store Bought Mustard
For sauces, I typically buy higher quality ingredients. A few of my favorite stone ground mustard brands are:
- Maille Whole Grain Old Style Mustard (quality, texture, depth)
- Inglehoffer Original Stone Ground Mustard (award winning, American)
- French's Stone Ground Dijon Mustard (when your feel like Dijon)
Place the heavy cream, stone ground mustard, and butter in a sauce pan over medium heat.

Use a whisk to combine the ingredients, then turn the heat down to medium-low heat and let the sauce simmer for a few minutes to thicken.
Continue to stir the sauce until it's nice and thick, remove the pan from the heat
Pour it into a sauce container, and you're ready to serve.
