Filet mignon steaks topped with buttery crab, tender asparagus, and a rich Béarnaise sauce. A classic steakhouse dish that comes together in about 30 minutes, no reservation required.
Wrap kitchen twine around each filet to help them cook evenly and season both sides generously with salt and pepper. Heat olive oil in a cast-iron skillet over medium-high until shimmering.
Sear steaks for about 2 minutes per side, including the edges (4 minutes total for medium-rare, 130°F internal).
Transfer to a plate, tent with foil, and let rest for 10 minutes. Remove the twine before serving.
Prepare the Asparagus
In the same skillet, add ¼ cup water and the asparagus and cook over medium-high heat until bright green and just tender, about 3 minutes.
Remove from heat, toss with butter, salt, pepper, and fresh tarragon.
Warm the Crab
Melt butter in a small non-stick skillet over medium heat.
Add crab meat and cook gently for 1–2 minutes until warmed through. Remove from heat and toss with lemon juice.
Assemble the Dish
Divide asparagus between two plates and top each with a filet. Spoon warm crab over the steaks.
Finish with a generous spoonful of Béarnaise sauce and garnish with extra tarragon, if desired.
Notes
Secure the steaks: Tying the filets with twine helps them hold their shape and sear more evenly.Get the pan hot: A well-heated cast iron skillet gives you that deep crust on the steaks. Just don’t overcrowd the pan, or the steaks will steam instead of sear.Heat the crab with care: Crab meat only needs quick warm-up in butter. Too long, and it can toughen.Let the steaks rest: A short rest after cooking keeps the juices in the meat, not on the plate.Add the sauce last: Béarnaise can break if overheated or left too long on the plate. Keep it warm and spoon it on right before serving.
