Ingredients

Scale
  • 12 ounces flank or skirt steak
  • 3 cloves garlic, minced
  • 2 tablespoons chopped fresh parsley
  • 2 tablespoons chopped fresh thyme
  • 3 tablespoons extra virgin olive oil
  • Salt and pepper to taste
  • 1 small baguette, sliced into ½-inch pieces
  • Horseradish cream:
  • ½ cup sour cream
  • 2 tablespoons prepared horseradish
  • 1 teaspoon Dijon mustard
  • 1 teaspoon freshly squeezed lemon juice
  • Salt and pepper to taste

Instructions

  1. Prepare the marinade by mixing olive oil, minced garlic, chopped parsley, thyme, salt, and pepper in a small bowl.
  2. Place the steak in a shallow dish or zip-top bag and coat fully with the marinade. Let sit at room temperature for at least 15 minutes or up to 2 hours in the fridge.
  3. Whisk together sour cream, prepared horseradish, Dijon mustard, lemon juice, salt, and pepper in a bowl. Chill until ready to serve.
  4. Preheat oven to 375°F (190°C). Arrange baguette slices on a baking sheet, brush lightly with olive oil, and toast for 8-10 minutes until golden and crisp, flipping halfway.
  5. Heat a cast iron skillet over medium-high heat until very hot. Remove steak from marinade, letting excess drip off, and sear for 3-4 minutes per side for medium-rare.
  6. Transfer steak to a cutting board, cover loosely with foil, and rest for 5-10 minutes. Slice thinly against the grain into bite-sized strips.
  7. Spread horseradish cream on each toasted baguette slice, top with steak slices, and garnish with fresh parsley or thyme if desired. Serve immediately.

Notes

Let steak rest after cooking to lock in juices. Adjust horseradish in cream to taste. Toast baguette slices carefully to avoid burning. For dairy-free, substitute sour cream with coconut yogurt and use plant-based mayonnaise.
