Why You'll Love This Recipe
- Prep takes just a few minutes.
- Perfect for holidays, sleepovers, or lazy Sundays.
- The texture is incredibly tender with buttery, caramel notes.
- Great way to use up stale bread.
- Family-friendly and perfect for crowd breakfasts.
- Smells like cinnamon perfection from the moment it warms.
INGREDIENTS
- 1 loaf stale brioche bread, sliced and cut into cubes
- ½ cup chopped pecans
- 8 large eggs
- 3 cups milk
- ¼ cup maple syrup
- 1 tablespoon vanilla extract
- 1 teaspoon salt
- 2 teaspoons cinnamon
- ½ teaspoon nutmeg
- 1 stick butter, sliced
- ½ cup brown sugar
- 1 teaspoon cinnamon (for topping)
Ingredient Notes & Substitutions
- Brioche: Its soft crumb and buttery flavor make the casserole rich and tender, but challah or thick Texas toast works well too.
- Milk: Whole milk gives the custard its creamy texture. You can use 2 percent or a mix of milk and half-and-half for extra richness.
- Pecans: Feel free to swap with walnuts or skip entirely if you want a nut-free version.
- Maple syrup: You can use honey or light brown sugar if needed, though maple adds a warm depth that really shines in this dish.
INSTRUCTIONS
- Prep the slow cooker. Spray the inside of your slow cooker with nonstick spray. This helps the edges brown softly while keeping cleanup easy.
- Layer the bread and pecans. Add the brioche cubes and sprinkle the chopped pecans throughout. I like to tuck a few pecans down between pieces so the flavor spreads evenly.
- Make the custard. In a large bowl, whisk the eggs, milk, maple syrup, vanilla, salt, cinnamon, and nutmeg. The mixture should look smooth, speckled with warm spices, and smell like a holiday morning.
- Pour over the bread. Let the custard seep into every nook and cranny. Give the top a gentle press so the bread absorbs the liquid.
- Mix the topping. Stir the brown sugar with 1 teaspoon cinnamon. Sprinkle it over the casserole for a buttery-sweet crust.
- Add the butter. Place the slices of butter evenly over the top. As it cooks, it melts into the bread and creates those caramelized edges everyone loves.
- Cook. Cover and cook on low for 4 hours or on high for 2 ½ hours. When it's done, the edges will be golden and the center will be soft but set.
- Serve. Scoop warm servings into bowls and enjoy immediately. A drizzle of maple syrup or a dusting of powdered sugar is pure joy.
Pro Tips for Success
Top Tip
- Stale bread absorbs the custard better. If your brioche is fresh, leave the cubes out for an hour or toast lightly.
- Press the bread down after pouring the custard so every piece soaks evenly.
- Lifting the lid toward the end lets a little steam escape, helping the top set more firmly.
- For extra texture, broil the finished casserole (in an oven-safe insert) for a minute or two to crisp the top.
- Let it rest 10 minutes after cooking so the custard settles before serving.
Storage and Reheating
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Reheat: Warm individual servings in the microwave for 30 to 45 seconds, or bake at 325 F until heated through.
- Freeze: Freeze portions for up to 2 months. Thaw overnight and reheat gently.
Make Ahead & Freezing
- Assemble the casserole the night before. Refrigerate the slow cooker insert, then place it back in the base when ready to cook.
- If freezing, skip the pecans and add them after thawing for the best crunch.
- You can also mix the custard up to 24 hours in advance.
Tips and Variations
- Add fruit: Blueberries, diced apples, or sliced bananas melt beautifully into the custard.
- Pumpkin twist: Add ½ cup pumpkin puree and a splash of extra cinnamon for a cozy autumn version.
- Healthier option: Reduce the brown sugar topping and use low-fat milk.
- Chocolate lovers: Add a handful of chocolate chips for a dessert-like brunch.
- Serving idea: Whipped cream or vanilla yogurt makes this feel like a bakery treat.
FAQs
Yes, but brioche or challah gives the best texture. Sandwich bread will be softer and more delicate.
Make sure the bread is stale and don't skip the resting time after cooking.
Only if your slow cooker is large enough. Overfilling makes it cook unevenly.
Absolutely. Bake covered at 350 F for 30 minutes, then uncover and bake until golden.
