Take your steak out of the refrigerator and let it come to room temperature. This helps it cook more evenly. Season generously with kosher salt, freshly ground black pepper, and the mushroom powder if using.

Preheat your oven to 350°F (175°C). Slice the sourdough baguette into approximately 1/2-inch thick rounds - you should get about 20-24 slices total. Arrange them on a baking sheet and toast in the oven for 6-8 minutes until just crisp but not too dark.

While the bread is toasting, heat a cast iron skillet with a drizzle of oil until it's really hot - almost smoking. Add your steak and sear for about 2 minutes on each side for medium-rare. For the perfect finish, transfer the skillet to the oven for another 1-2 minutes until your desired doneness is reached.

Remove the steak from the oven and let it rest on a cutting board for about 15 minutes. This crucial step lets the juices redistribute throughout the meat. After resting, thinly slice the steak against the grain.

Once your bread slices are toasted, take a raw garlic clove and gently rub it across the surface of each toast. This gives a subtle but aromatic garlic flavor. Top each toast with a spoonful of creamy burrata, then add a slice or two of the steak.

Garnish your crostini with a sprinkle of finely chopped fresh chives, a light dusting of flaky sea salt, a final crack of black pepper, and a delicate drizzle of balsamic vinegar. Serve immediately while still warm for the best experience!
