Cognac Dijon Filet Mignon

Quick Answer

Cognac Dijon Filet Mignon sears and roasts filets, then builds a classic pan sauce of Cognac, cream, Dijon, and tarragon.

Jump to Recipe

Filet mignon is tender enough that it does not need much help from you, which is exactly why a good pan sauce earns its place. This one pairs the mild beef with Cognac, Dijon mustard, beef stock, heavy cream, shallot, and fresh tarragon—a sauce with enough sharpness and aroma to make filet interesting without covering up the reason you bought filet in the first place.

The steaks start simply with salt and pepper, sear for three minutes per side, then finish in a 425°F oven until they reach 125–135°F. Rest them for eight minutes while you make the sauce in the same skillet. Cook the shallot briefly, take the pan away from the flame before adding Cognac, then return it to the heat and reduce. Beef stock concentrates next; cream, Dijon, and tarragon finish the sauce in the final few minutes. That off-flame Cognac step is not theatrical caution. Alcohol vapor and open flame have a relationship that can become memorable very quickly. Keep the excitement on the plate, spoon the finished sauce over the rested filets, and enjoy the kind of 30-minute dinner that makes Tuesday look like it has a reservation.

Pro Tips

  • Take the pan off the flame before adding the Cognac, then set it back on the heat. Splashing liquor into an open flame is a genuine fire hazard.
  • Reduce the stock by half before adding cream, so the final sauce has real depth instead of tasting thin.
  • Add the tarragon at the end. Its delicate anise flavor fades if you cook it too long.

Substitutions

Cognac → brandy or dry white wine Brandy is nearly identical; white wine is lighter but still deglazes well.
fresh tarragon → ½ teaspoon dried tarragon or fresh chives Dried is more potent, so use less; chives change the flavor but keep it fresh.
filet mignon → thick-cut top sirloin or strip steak Both work with the pan sauce; adjust cook time to the cut.

Storage Instructions

Store leftover filet and sauce in the refrigerator for up to 3 days. Reheat gently over low heat with a splash of stock or cream to loosen the sauce.

Make Ahead

Filet is best cooked fresh. You can mince the shallot and measure the sauce ingredients ahead so the à la minute sauce comes together fast.

Freezing

Cream-based pan sauces can split when frozen, so make this one fresh. Cooked filet can be frozen but loses its signature tenderness.
