Savory Mustard Sauce
Ingredients
Directions
Make the sauce
Heat olive oil in a large sloped-sided skillet over medium-high heat.
Add shallot and sauté until golden.
Meanwhile, combine broth and starch and set aside.
Add mustard, salt, and pepper to the pan and decrease heat to medium-low.
Add the broth mixture, whisking continuously until the sauce just below a simmer thickens slightly.
Whisk in butter 1 tablespoon at a time, waiting for the previous butter to fully melt before adding another.
Once all butter has been used, remove the sauce from heat.
Serve
Serve with steak or pork tenderloin, or use as a grilling baste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dijon mustard
- Provides the main sharp, tangy flavour of the sauce.
- Cornstarch
- Thickens the broth so the sauce becomes smooth and glossy.
- Chicken broth
- Forms the liquid base that the starch thickens into the sauce.
- Unsalted butter
- Adds richness and a silky, emulsified texture when whisked in at the end.
- Shallot
- Adds a mild, sweet aromatic onion flavour after being sautéed.
The step that matters
Whisking in the butter. Adding butter too fast or while the sauce is too hot can cause it to separate instead of forming a smooth emulsion. Adding one tablespoon at a time and letting each melt fully keeps the sauce creamy and cohesive.
Swap the shallot
How well each one fits the dish's main ingredients (mustard, chicken, pepper, olive, butter):
- Capsicumfits better
- Potatofits better
- Tomatofits better
- Shallotthe original
