A French bistro classic that turns a humble but flavorful cut into a restaurant-worthy dinner. Flatiron steak is seared hard and fast in a screaming-hot skillet to build a deep, caramelized crust, then rested while the same pan becomes the base for an irresistible shallot sauce.

Sweet, softened shallots and fresh thyme are deglazed with sharp red wine vinegar, mellowed with a beef broth reduction, and finished off the heat with butter, Dijon mustard, and fresh parsley for a sauce that’s silky, tangy, and richly savory all at once.
Sliced thin against the grain and draped in that glossy sauce, this is steakhouse-quality comfort food that comes together in well under an hour — perfect for a special weeknight dinner or an easy way to impress guests without much fuss.
We decided to go heavy on the shallots and used 3 large. For sides, we paired ours with some homemade mac ‘n cheese and a side salad.

Seared Flatiron With Shallot Sauce (Steak à l’Échalote)
Ingredients
- â…” cup low-sodium beef broth
- 2 (1-lb.) flatiron steaks, at room temperature
- Sea salt and coarsely ground black pepper
- 2 tsp. extra-virgin olive oil
- 4 Tbsp. unsalted butter, softened
- 1 cup minced shallots (from 2 large shallots)
- 1 sprig fresh thyme, leaves picked (about 1 tsp.)
- ¼ cup red wine vinegar
- ¼ cup minced fresh parsley
- 1½ tsp. Dijon mustard
- Watercress or baby arugula microgreens, for garnish (optional)









Directions
- Add broth to a small saucepan. Simmer over medium-high until reduced by half, 4 to 5 minutes. Set aside.
- Pat steaks dry with a paper towel and season with salt and pepper. Place a wire rack inside a baking sheet and set aside.
- Heat a large skillet (preferably cast iron or carbon steel and big enough to fit both pieces of steak) over medium-high. Add olive oil and heat until oil is shimmering, about 1½ minutes. (Note: If you do not have a skillet large enough to accommodate both steaks, use two skillets, adding 1 teaspoon of oil to each. Then use one of the skillets to prepare the sauce in Step 5.)
- Sear steaks on both sides until browned and cooked to desired doneness (2½ to 3 minutes per side for medium-rare. Ours took longer due to its thickness). Transfer steaks to the prepared rack to rest and tent loosely with foil to keep warm.
- Reduce heat to low and add the butter and shallots to the same skillet. Cook gently, stirring occasionally, until shallots have begun to soften but are barely colored, about 2 minutes. Stir in thyme leaves. Add the vinegar, increase the heat to medium-high and cook until the liquid has nearly evaporated, 2 minutes. Stir in the parsley, mustard and reserved reduced beef stock. Simmer until shallot mixture is soft and the sauce looks silky, about 2 minutes more. Remove from heat. Pour any juices that have escaped from the steaks during resting into the skillet.
- Using a sharp knife, slice the steaks across the grain on the bias. Arrange the slices on a platter. Spoon the shallot sauce over, garnish with greens if desired, and serve.
