- Baking Time: 45 minutes
- Total Time: 1 hour 35 minutes
Yield
Serves 8 generous portions, ideal for family brunches or small gatherings.
Difficulty Level
Medium – approachable for any home cook eager to elevate their breakfast repertoire.
Ingredients
- 1 loaf (about 12 oz) brioche bread, day-old preferred, cut into 1-inch cubes
- 6 large eggs, lightly beaten
- 2 cups whole milk (or half-and-half for extra creaminess)
- ½ cup heavy cream
- ½ cup granulated sugar
- 2 tsp pure vanilla extract
- 1 tsp ground cinnamon
- ¼ tsp ground nutmeg
- Pinch of salt
- butter for greasing the baking dish
- Optional toppings: fresh berries, chopped nuts, maple syrup, whipped cream, or mascarpone
Instructions
- Prepare your brioche: Cut the brioche loaf into evenly sized 1-inch cubes. This size ensures the bread soaks evenly without becoming mushy or dry.
- Mix the custard: In a large bowl, whisk together the eggs, whole milk, heavy cream, sugar, vanilla extract, cinnamon, nutmeg, and salt until fully combined and smooth.
- Soak the brioche: Gently fold the brioche cubes into the custard mixture, pressing them down so each piece absorbs the liquid. Cover and let it soak for at least 30 minutes at room temperature, or refrigerate overnight for immersive flavors and maximum tenderness.
- Preheat your oven: Set it to 350°F (175°C). Generously butter a 9×13-inch baking dish to prevent sticking and add a subtle richness to the crust.
- Transfer and spread: Evenly arrange the soaked brioche cubes in the prepared dish, pressing gently to fill any gaps and ensure a uniform bake.
- Bake uncovered: Place the casserole in the oven and bake for 45-50 minutes, until the top is golden brown and the custard is set but still tender inside. A knife inserted should come out mostly clean with slight moistness.
- Rest before serving: Allow the casserole to cool for 10 minutes to let the custard set further and enhance the fluffy texture.
- Top creatively: finish with a dusting of powdered sugar,fresh berries,a drizzle of pure maple syrup,or a dollop of whipped mascarpone for elevated flavor and visual appeal.
Tips for Success
- choosing brioche: Opt for a traditional brioche loaf with a rich butter content and a slightly dense crumb.Avoid overly soft or pre-sliced breads that won’t hold up during soaking and baking.
- Optimize soaking: Overnight soaking enhances not only texture but intensifies flavor. If short on time, 30 minutes at room temperature still delivers a pleasantly moist casserole.
- Custard variations: Substitute almond or oat milk for a dairy-free twist,but add a tablespoon of melted vegan butter to maintain richness.
- Make ahead and store: Assemble the casserole in the baking dish, cover tightly, and refrigerate overnight.Bake fresh on your serving day. Reheat individual servings in the oven or toaster oven for a crisp top.
- Flavor boosters: Mix in chopped chocolate chips, orange zest, or a splash of flavored liqueurs like Grand marnier into the custard for a gourmet touch.
Serving Suggestions
