This easy Sourdough French Toast recipe turns day-old sourdough bread into a cozy, custardy breakfast everyone loves. Thick slices soak up a maple-cinnamon custard, then cook up golden and crisp on the outside with a soft, fluffy center. Serve with stewed apples and fresh fruit for the ultimate weekend brunch.

3large eggs

1tspground cinnamon
½tspvanilla extract

3Tbspunsalted butterfor the griddle
To serve: maple syruppowdered sugar, berries
Instructions
In a wide, shallow dish, whisk together half and half, eggs, maple syrup, cinnamon, vanilla, and salt until smooth. (Same mix as your base.)
Dip each slice and soak 40–45 seconds per side (a touch longer than brioche/challah). Transfer to a rack or sheet pan for 1–2 minutes so the custard migrates inward. Your base calls for ~30 seconds per side; sourdough benefits from a bit more.
Heat a non-stick griddle or large skillet over medium to medium-low. Melt 2 Tbsp butter. Add four slices; cook until deep golden, 3–4 minutes per side, adjusting heat so the centers set without scorching. Repeat with remaining butter and slices. (Method mirrors your pan/griddle approach.)
Dust with powdered sugar and top with fruit and warm maple syrup, though thanks to the maple in the custard, they’re already flavorful.
Notes
Bread: Day-old sourdough works best because it soaks up the custard without getting soggy. If your loaf is very fresh, dry the slices in a low oven for 10-15 minutes.
Slice thickness: Aim for 3/4-inch slices for that custardy middle; for very airy loaves you can go up to 1-inch and increase the soak time slightly.
Heat: Cook over medium to medium-low so the sourdough crust doesn’t burn before the custard is set.
Make-ahead: Cooked French toast slices can be refrigerated up to 3 days. Reheat on a rack in a 350°F oven until hot and crisp.
Freezer-friendly: Freeze cooled slices in a single layer, then transfer to a freezer bag. Reheat from frozen in the oven or toaster.
