What is the most common mistake in making French toast?

The most common mistake is using bread that is too fresh and too thin. Soft, fresh sandwich bread collapses when soaked and produces a mushy texture. Use thick-cut, slightly stale brioche, challah, or French bread that can hold its structure through a long custard soak and retain a tender but defined crumb after baking.

What is the secret to good French toast?

The secret is a balanced custard ratio and enough soak time. You want approximately one egg for every quarter cup of dairy. Too many eggs create a rubbery, scrambled-egg texture. Too much milk and the toast turns pale and steams instead of browning. For a baked casserole, the overnight rest ensures full saturation so every bite bakes evenly.

What bread should I use for peach french toast?

Brioche is the top choice because its high butter and egg content gives it a rich flavor and a sturdy crumb that holds up beautifully through an overnight soak. Challah is a close alternative with a slightly less sweet profile. A thick-cut bakery French bread loaf works well if you prefer a chewier, less rich result. Avoid thin sandwich bread entirely.

How long should you soak French toast?

For a stovetop slice, 30 to 60 seconds per side in the custard is enough. For a baked casserole like this peach french toast recipe, the minimum soak is 4 hours, but 8 hours overnight gives the best result. The extended soak allows the custard to reach the very center of thick bread slices, so the finished casserole is custardy all the way through rather than dry in the middle. ---

Instructions

1. Preheat the oven to 350 degrees F. Place a 9×13-inch baking dish in the oven for 2 minutes to warm it, then add the butter and let it melt completely. Remove from the oven, stir in the brown sugar and cinnamon until you have a thick paste coating the bottom, then arrange the peach slices in a single overlapping layer over the sugar mixture.

2. Arrange the bread slices upright in the dish, like cards in a deck, fitting them snugly against the peaches and each other. Tuck smaller pieces into any gaps so the dish is tightly packed.

3. In a medium bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, cinnamon, and salt until completely smooth with no streaks of egg yolk remaining.

4. Pour the custard slowly and evenly over the bread slices, making sure each piece is well coated. Press down gently on the bread tops to encourage the custard to absorb into every slice.

5. Cover the dish tightly with plastic wrap and refrigerate for at least 8 hours or up to 12 hours. In the morning, remove the casserole from the refrigerator and let it sit on the counter for 20 minutes while the oven preheats to 350 degrees F.

6. Bake uncovered for 40 to 45 minutes, until the top is deep golden brown and the center no longer jiggles when you gently shake the dish. If the top browns too quickly, tent loosely with foil for the final 10 minutes.

7. Remove from the oven and let the casserole rest for 5 minutes. Scoop portions out and invert them onto plates so the caramelized peach layer faces up. Dust with powdered sugar and drizzle with warm maple syrup before serving.

Notes

Store leftovers covered in the refrigerator for up to 3 days. Reheat individual portions at 325 degrees F for 10 minutes or microwave on 50 percent power for 90 seconds. Freeze assembled unbaked casserole wrapped tightly for up to 1 month and thaw overnight in the refrigerator before baking.

Bread tip: Use brioche or challah that is at least one day old. Fresh, soft bread absorbs too much liquid and turns mushy. Slightly stale bread holds its structure through the overnight soak.

Peach tip: If using frozen peaches, thaw and drain them completely before using to prevent a watery caramel base. If using canned peaches in juice, reduce the brown sugar in the base by 1 tablespoon.

Custard ratio: Do not increase the eggs beyond 4 for this size casserole. Too many eggs create a rubbery, dense texture rather than a soft, custardy one.
