1 cup (2 sticks) unsalted butter, at room temperature
1 tablespoon dried parsley leaves
½ teaspoon kosher salt
½ cup finely shredded Parmesan cheese (about 2 ounces)
1 loaf French Bread (from Magnolia Table, Volume 3)
Directions
Preheat the oven to 400ºF. Line a baking sheet with foil.
Peel the excess papery skin off the head of garlic and trim the top, exposing the garlic cloves. Drizzle with the olive oil. Wrap the garlic in foil, keeping the top exposed.
Roast directly on the oven rack for 45 minutes, then carefully remove the garlic from the foil and let cool for about 15 minutes. Squeeze the cloves into a small bowl, discarding the skin.
Using a stand mixer fitted with paddle attachment, whip the butter on medium-high speed until pale and fluffy, about 2 minutes. Add the roasted garlic cloves, parsley, and salt, and continue mixing on high for about 1 minute to fully incorporate the flavors. Slowly add the Parmesan and mix on medium-low speed until incorporated.
Slice the bread in half lengthwise and place it cut side up on the lined baking sheet. Divide the butter mixture between the halves and spread evenly.
Bake for 15 minutes, then broil on high for about 1 minute to make the edges crispy. Allow the toast for cool for about 5 minutes. Cut into slices and serve.
Store in an airtight container at room temperature for up to 3 days.
