Slices of brioche or challah soak up a vanilla-scented egg and half-and-half custard while pockets of brown-sugared peaches release syrupy juices as they roast, creating a contrast between tender fruit and the golden, slightly crisped top. The small knobs of butter dotted across the surface melt into the bread for a rich finish, and a dusting of cinnamon ties the whole thing together. What makes this version work is thoughtful layering and a little patience: macerating the peaches softens them and concentrates sweetness, while using day-old brioche or challah gives the casserole structure so it stays custardy without collapsing into mush. It’s a forgiving, make-ahead dish that scales from a quiet family breakfast to a casual brunch for friends — assemble it the night before, bake in the morning, and you’ll have mouths singing for the sticky, buttery edges and the spoonable, custard-soaked center. Serve simply with warm maple syrup, a scoop of whipped cream, or a tangy dollop of crème fraîche. ## Recipe Information - Prep Time: 20 minutes - Cook Time: 45 minutes - Total Time: 65 minutes - Servings: 7 - Difficulty: Easy - Category: Breakfast ## Ingredients ### Macerate the peaches - 3 cups ripe peaches, peeled and sliced - 1/2 cup packed brown sugar - 1 1/2 teaspoons ground cinnamon ### Whisk the custard - 5 count large eggs - 2 cups half-and-half - 1 teaspoon vanilla extract - 1/2 teaspoon kosher salt ### Assemble the casserole - 8 cups stale brioche or challah, cut into 1-inch cubes - 2 tablespoons unsalted butter, cut into small knobs ## Ingredient Guide ### stale brioche or challah, cut into 1-inch cubes Brioche is a rich French egg-and-butter bread and challah is a slightly sweet braided Jewish egg bread; both have an airy, tender crumb and a subtly sweet, buttery flavor. They’re used in recipes like bread pudding or French toast because they soak up custard without falling apart. You can find them at bakeries, many supermarkets, or in the bakery aisle; if unavailable, substitute a day-old enriched white sandwich loaf, croissants, or another sturdy slightly sweet bread. ## Instructions ### 1. Macerate the peaches In a medium bowl, toss the peeled and sliced peaches with the packed brown sugar and 1 teaspoon of the ground cinnamon. Let the mixture sit 10–15 minutes at room temperature so the peaches release juices; if preparing ahead, cover and chill overnight to meld flavors. ### 2. Whisk the custard In a large bowl, whisk together the eggs, half-and-half, vanilla extract, the remaining 1/2 teaspoon ground cinnamon, and kosher salt until smooth. The custard should be well combined and slightly frothy so it soaks evenly into the bread. ### 3. Assemble the casserole Butter a 9x13-inch (or similar) baking dish. Spread half of the cubed brioche in the dish, scatter half of the macerated peaches and their juices over the bread, then repeat with the remaining bread and peaches. Press gently to compact, dot the top with the knobs of unsalted butter, then pour the custard evenly over the casserole, pressing down so the bread soaks up the liquid. ### 4. Chill to make ahead (recommended) Cover the assembled dish tightly with plastic wrap and refrigerate for at least 4 hours or overnight — this step makes the casserole wonderfully custardy and convenient for weekend mornings or brunch service. If baking immediately, let the casserole sit 20–30 minutes so the bread absorbs the custard. ### 5. Bake until golden and set Preheat the oven to 350°F (175°C). Uncover the casserole and bake on the middle rack for 40–45 minutes, or until the top is puffed and golden and a knife inserted into the center comes out mostly clean. If the top browns too quickly, tent loosely with foil for the last 10–15 minutes. ### 6. Rest and serve Let the casserole rest 10 minutes before serving to set. Serve warm in portions of about 1½ cups (about 350g) per person with maple syrup, a dusting of powdered sugar, or a dollop of whipped cream as desired. ## Nutrition Estimated nutrition per serving (about 2 cups): - Calories: 469 kcal - Protein: 12.9 g - Carbohydrates: 69.3 g - Fat: 16.1 g - Saturated Fat: 7.7 g - Trans Fat: 0.3 g - Fiber: 1.5 g - Sugar: 32.4 g - Added Sugars: 0 g - Cholesterol: 36 mg - Sodium: 832 mg - Potassium: 199 mg - Calcium: 225 mg - Iron: 1.8 mg - Vitamin D: 0 mcg ## Tips ### Use day-old bread Slightly stale brioche or challah absorbs the custard without turning to paste; if your bread is fresh, toast cubes briefly to dry them out. ### Macerate peaches longer Letting the peaches sit with brown sugar and cinnamon for an hour (or overnight) draws out juices and creates a saucier, more flavorful layer. ### Cut uniform cubes Cut 1-inch bread cubes so they hydrate and bake evenly; uneven pieces result in patches of dry bread and overly soggy areas. ### Press before chilling After layering, press the bread down gently to ensure good contact with the juices and custard so the interior becomes uniformly custardy. ### Tent if over-browning If the top is browning too fast, loosely tent with foil for the last 10–15 minutes to finish cooking the center without burning the surface. ## Variations and Substitutions ### Dairy-free swap Replace half-and-half with full-fat canned coconut milk (use a light whisking so it’s smooth) for a dairy-free version; expect a slightly richer, tropical flavor. ### Gluten-free option Use a sturdy gluten-free brioche or a firm gluten-free sandwich loaf cut into cubes, and follow the same soak and bake times, watching for browning. ### Boozy peach version Add 1–2 tablespoons bourbon or dark rum to the macerated peaches (or to the custard) for a warm, boozy depth that pairs beautifully with the brown sugar. ### Apple–peach hybrid Stir 1–2 cups thinly sliced tart apples (like Honeycrisp) into the peaches and increase cinnamon by 1/4 teaspoon for a fall-friendly twist with more texture. ## Notes This casserole is perfect for relaxed weekend mornings or a casual brunch — prepare it the night before so baking is the only thing between you and a hot, peach-scented breakfast. Home cooks will love how peaches roast into syrupy pockets that meld with the custardy bread. ### Storage and Make-Ahead Store leftovers tightly covered in the refrigerator for up to 3–4 days. To freeze, portion into airtight containers and freeze for up to 2 months; thaw overnight in the fridge before reheating. Reheat individual portions in a 350°F oven for 10–15 minutes or in the microwave for 60–90 seconds until warmed through, then refresh with a quick blast under the broiler if you want to re-crisp the top. ### Serving Suggestions Serve warm with a drizzle of good maple syrup and a spoonful of whipped cream or crème fraîche to balance the sweetness. For a savory contrast, offer crisp bacon or breakfast sausage and a simple arugula salad dressed with lemon to cut through the richness. Pair with strong coffee, a citrusy sparkling wine, or cold-brewed iced tea for a complete brunch spread. ## Frequently Asked Questions ### Can I use frozen peaches? Yes — thaw and drain excess liquid, then macerate with the brown sugar so they don’t add too much extra moisture; you may need to reduce any added juices before assembling. ### How ripe should the peaches be? Choose peaches that are ripe but still slightly firm; overly soft fruit can turn to mush when macerated and baked, while underripe peaches won’t release enough juice or flavor. ### What if I don’t have half-and-half? You can use whole milk for a lighter custard or a mix of equal parts milk and heavy cream to mimic half-and-half; avoid skim milk, which produces a thinner custard. ### How do I prevent a soggy bottom? Use slightly stale bread and press the layers so the custard distributes evenly; also ensure your baking dish is prepped with butter and bake on the middle rack to encourage even heat circulation. ### Can I assemble it the night before? Absolutely — assembling and refrigerating overnight improves texture and flavor; cover tightly and bake straight from the fridge, adding a few extra minutes to the bake time if still very cold. ### Can I halve or double the recipe? Yes — halve for a smaller 8x8 pan and bake about 30–35 minutes, or double in two 9x13 pans (or a larger pan) and monitor baking time, which may increase by 10–15 minutes depending on depth. ## Related Recipes and Guides - [Pumpkin Oat Muffins](https://www.topshelf.recipes/recipes/pumpkin-oat-muffins) - [Chocolate Chip Banana Muffins](https://www.topshelf.recipes/recipes/brown-butter-chocolate-chip-banana-muffins) - [Pad Krapow Pork](https://www.topshelf.recipes/recipes/pad-krapow-pork) - [Canning Peaches Light Syrup](https://www.topshelf.recipes/recipes/canning-peaches-light-syrup) - [Easy Homemade Yogurt Without Special Equipment](https://www.topshelf.recipes/recipes/easy-homemade-yogurt-without-special-equipment) - [Maple Bacon Butter Board with Cracked Pepper and Toastables](https://www.topshelf.recipes/recipes/maple-bacon-butter-board-cracked-pepper-toastables) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan) - [Low-Fat Grill Swaps for Big Flavor](https://www.topshelf.recipes/articles/low-fat-grill-swaps-big-flavor) - [DIY Edible Monster Eyes Candy](https://www.topshelf.recipes/articles/diy-edible-monster-eyes-candy)
