Steak with Creamed Mustard Sauce (Steak a la Moutarde)

The French language makes foods sound so fancy and expensive. Case in point, moutarde, the French word for the pedestrian condiment that adorns hot dogs and pretzels in the US: mustard. Not that mustard can’t be elevated to create dishes like Steak a la Moutarde and Pollet (chicken) a la Moutarde! Mustard is the inspiration for this rich, velvety sauce with cream and butter, a sauce so good with steak that it makes this pan fried dish exquisite.  

Steak a La Moutarde – Pan fried Steak with Mustard Sauce

This dish can be found served at many a bistro and brasserie throughout France. The assertive mustard sauce is softened by a little cream and perfectly cooked steak. It is often served with pomme frites (thin French fries) or mashed potatoes to soak-up the flavorful juices leaking from the steak along with the mustard-cream sauce. A green vegetable, nice red wine, and crusty baguette will transport diners directly to a small Parisian bistro for the night.
