FAQs

Instructions

1. Generously coat the steak with a blend of salt, black pepper, garlic powder, and dried thyme. Allow the seasonings to permeate the meat for a minimum of 30 minutes at room temperature.
2. Whisk together mayonnaise, horseradish, mustard, and a splash of lemon juice. Season the creamy mixture with salt and pepper, then refrigerate to meld the flavors.
3. Melt butter in a skillet over medium heat, sautéing shallots until translucent and tender. Deglaze with vinegar and sprinkle sugar, slowly caramelizing the shallots to a rich golden brown.
4. Grill or pan-sear the steak to your preferred level of doneness (recommended 3-4 minutes per side for medium-rare). Transfer to a cutting board and let rest for 5-7 minutes before slicing into delicate, thin strips.
5. Lightly brush baguette slices with olive oil and toast at 375°F until crisp and golden, approximately 5-7 minutes.
6. Layer each crostini with a generous spread of the chilled horseradish sauce, top with tender steak strips, and crown with the caramelized shallots.
7. Finish by scattering fresh thyme or finely chopped parsley as a vibrant garnish.

• Allow steak to reach room temperature before cooking to ensure even heat distribution and more consistent doneness.
