French Toast Recipe With Deep-Soaked Vanilla Custard

• Day-old challah has a slightly dry crumb that absorbs custard without collapsing as quickly as fresh, soft bread. Thick slices also give the center time to turn tender before the exterior gets dark.
• Using both milk and half-and-half keeps the custard pourable, so it moves through bread during a short soak rather than sitting as a heavy coating. Vanilla, cinnamon, and salt keep the flavor direct.
• Moderate skillet heat is deliberate. It gives the soaked interior time to cook while butter builds an even brown surface, and batches stay manageable on an ordinary weekday.

• 8 thick slices day-old challah, about 1 inch thick (450 g)
• 4 large eggs (200 g)
• 1 cup whole milk (240 g)
• 1/2 cup half-and-half (120 g)
• 2 tablespoons granulated sugar (25 g)
• 2 teaspoons pure vanilla extract (10 g)
• 1/2 teaspoon warm ground cinnamon (1 g)
• 1/4 teaspoon kosher salt (1 g)
• 3 tablespoons unsalted butter, divided (42 g)
• 3/4 cup maple syrup and 1 cup berries, for serving (180 g)

Ingredient notes

• Challah is the best fit here because its enriched crumb stays cohesive after soaking. Buy a loaf one day ahead, or leave slices uncovered on a rack for several hours to dry their cut surfaces.
• Whole milk keeps the custard fluid enough to penetrate the bread. Do not replace all of it with cream, which makes a thicker mixture that tends to coat the outside before the middle has absorbed much.
• Half-and-half adds richness without turning the custard dense. If needed, use additional whole milk instead; the finished slices will be lighter, but the soaking method and cooking time remain the same.
• Use large eggs and whisk until no visible strands remain. A thoroughly blended custard cooks more evenly, so the center of each slice has the same tender texture as its edges.
• Vanilla extract, cinnamon, and kosher salt give the custard definition without overwhelming the bread. Freshly grated nutmeg is optional, but use only a small pinch because it can quickly dominate the maple syrup.
• Unsalted butter browns gently and lets you control the salt level. Wipe away very dark bits between batches, then add fresh butter so later slices do not pick up a bitter flavor.

1. 1Dry the bread

   Arrange the challah slices on a wire rack and leave them uncovered for at least 2 hours, or use day-old bread. The surface should feel dry while the centers remain soft. Dry bread takes in custard steadily instead of tearing when lifted from the dish.

2. 2Whisk the custard

   In a wide, shallow baking dish, whisk eggs, whole milk, half-and-half, sugar, vanilla, cinnamon, and salt until smooth. Scrape along the dish corners with the whisk. A shallow dish matters because it exposes both broad sides of every slice to the liquid.

3. 3Soak both sides

   Lay two slices in the custard without crowding them. Soak 3 minutes, turn carefully, and soak 3 minutes more. Press each slice very lightly with a spatula once after turning; this encourages absorption without squeezing out the bread's interior structure.

4. 4Heat the skillet

   Set a large nonstick or well-seasoned skillet over medium-low heat for 3 minutes. Add 1 tablespoon butter and swirl when it foams. The butter should sizzle quietly, not smoke. Keep the heat moderate so the custard cooks through before the surface becomes too dark.

5. 5Cook gently

   Lift soaked bread, letting excess custard drip back into the dish for a few seconds. Cook two slices for 3 to 4 minutes per side, until deeply golden. Check the center of the thickest slice; continue cooking until it reaches 160°F.

   

6. 6Finish in batches

   Move cooked slices to a rack set over a sheet pan, not a stacked plate. Add remaining butter and repeat with the last slices. Rest the finished French toast 2 minutes before serving, which lets steam settle and keeps the browned surface from turning damp.

   

• Keep the custard in a shallow dish rather than a bowl. Broad contact with the bread is what makes a six-minute soak useful, and it prevents awkward flipping with dripping slices.
• Do not rush with high heat. If butter browns before a slice has cooked for two minutes, lower the burner and wipe out the skillet before adding fresh butter.
• Use a thin, wide spatula to turn the soaked bread. A narrow utensil can split the softened center, especially with very thick challah slices.
• Hold cooked slices on a wire rack, never directly on a plate. Air underneath preserves the browned exterior while you finish the remaining batches.

Serve two warm slices with maple syrup, sliced bananas, berries, or a spoonful of Greek yogurt. For a less sweet plate, add crisp bacon or breakfast sausage and keep the syrup at the table. A dusting of powdered sugar is optional, not required. If cooking for several people, place the rack in a 200°F oven while batches finish, then bring everything to the table together with butter and fruit.
