Ingredients
Scale
Protein:
- 1 pound sirloin (tenderloin steak, or filet mignon)
Seasonings:
- Salt (to taste)
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- Black pepper (to taste)
Bread and Oil:
- Baguette (thinly sliced)
- Olive oil for brushing
Butter and Cooking Fats:
- 2 tablespoons unsalted butter
Caramelized Shallots:
- 2 large shallots (thinly sliced)
- 1 tablespoon balsamic vinegar
- 1 tablespoon brown sugar
- Salt (to taste)
- Black pepper (to taste)
Creamy Horseradish Sauce:
- 1/2 cup mayonnaise
- 2 tablespoons prepared horseradish
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh lemon juice
- Salt (to taste)
- Black pepper (to taste)
- 2 tablespoons unsalted butter
Instructions
- 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.
- 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.
- 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.
- 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.
- Lightly brush baguette slices with olive oil and toast at 375°F until crisp and golden, approximately 5-7 minutes.
- Layer each crostini with a generous spread of the chilled horseradish sauce, top with tender steak strips, and crown with the caramelized shallots.
- Finish by scattering fresh thyme or finely chopped parsley as a vibrant garnish.
Notes
- Marinate the steak longer for deeper flavor infusion, letting seasonings penetrate the meat thoroughly.
- Try different mustards like Dijon or whole grain for varied tangy undertones in the horseradish sauce.
- Use gluten-free baguette or lettuce wraps to make this recipe celiac-friendly and low-carb adaptable.
- Allow steak to reach room temperature before cooking to ensure even heat distribution and more consistent doneness.
