This garlic sourdough toast recipe combines sourdough bread, butter, garlic, parsley, white pepper, and Parmesan cheese for a crispy, golden side dish. Ready in under 15 minutes, it's perfect alongside pasta, soup, chicken, fish, or salad.
Preheat the oven to 400°F / 200°C (350°F convection / 180°C fan).
In a mixing bowl, combine the ½ cup (115 g) softened salted butter, 4 minced garlic cloves, ¼ cup (15 g) chopped parsley, ¼ teaspoon white pepper, and ½ cup (45 g) grated Parmesan cheese. Stir until smooth and well combined.
Spread the garlic butter evenly over each slice of sourdough bread. Place the sourdough slices on a baking sheet, buttered side up.
Bake for 7–8 minutes, or until the edges are golden and crisp. Broil for 1–2 minutes at the end for an extra crispy top, if desired.
Let cool slightly, then serve warm or cold.
Notes
Use Softened Butter: I like letting the butter sit at room temperature first because it mixes much more easily with the garlic, parsley, and Parmesan.Freshly Grated Parmesan Works Best: I find freshly grated Parmesan melts into the butter mixture better and gives the toast a richer flavor.Keep an Eye on the Oven: Sourdough can brown quickly, so I start checking during the last minute or two of baking.Reheat in the Oven: I store leftovers in the refrigerator for up to 2 days and warm them in the oven for a few minutes to bring back the crisp texture.
