Key Ingredients & Smart Swaps
- Brioche or Challah Bread: Sturdy, egg-rich brioche holds its shape beautifully without breaking down. Use day-old bread or dry freshly sliced cubes in a 300°F oven for 10 minutes.
- Pure Pumpkin Puree: Be sure to choose 100% pure pumpkin puree (like Libby’s) rather than pre-spiced pumpkin pie filling, so you control the sweetness and spice balance.
- Whole Milk & Heavy Cream: A blend of whole milk and cream yields an ultra-velvety custard. You can swap in oat milk or full-fat coconut milk for a dairy-free variation.
- Pumpkin Pie Spice & Cinnamon: A robust blend of cinnamon, ginger, nutmeg, allspice, and cloves infuses every bread cube with authentic bakery warmth.
- Chopped Pecans: Crisp raw pecans toast in the oven inside the brown sugar butter streusel, creating an irresistible praline crunch. Walnuts or sliced almonds work wonderfully too.
Step-by-Step Cooking Walkthrough
1. Prep the Bread: Cut day-old brioche into 1-inch cubes and scatter evenly across a buttered 9×13-inch ceramic baking dish.
2. Whisk the Custard: Whisk pumpkin puree, eggs, milk, cream, maple syrup, vanilla, pumpkin pie spice, and salt until smooth and velvety.
3. Soak & Chill: Pour custard over the bread, pressing gently so each piece is soaked. Bake right away or cover and chill overnight in the refrigerator.
4. Streusel & Bake: Scatter the crumbly brown sugar pecan topping over the casserole. Bake at 350°F (175°C) for 40 to 45 minutes until puffed, fragrant, and golden brown.
3 Chef Secrets for Perfect Results
1. Use Dry, Stale Bread: Fresh soft bread absorbs liquid too fast and dissolves into mush. Slightly stale or lightly oven-dried brioche acts like a sponge, retaining delightful crumb structure while holding generous custard.
2. Keep the Streusel Butter Cold: When making the streusel topping, use cold, cubed butter. Cold butter creates pea-sized clumps that melt slowly in the oven, creating crispy, crunchy pockets rather than melting into a flat glaze.
3. Let It Rest for 10 Minutes: As tempting as it is to dig in immediately, letting the baked casserole rest allows the custard to finish setting so every slice holds its clean, square bakery shape.
What to Serve With Pumpkin French Toast Casserole
- Warm Pure Maple Syrup: Grade A amber maple syrup warmed gently in a saucepan brings out the rich caramel tones of the brown sugar streusel.
- Fresh Fruit & Berries: Fresh tart blackberries, blueberries, or fresh orange slices to balance the sweet spiced custard.
- Savory Brunch Pairings: Pair with crispy beef bacon or halal turkey sausage links, or our savory sheet pan sweet potato and egg breakfast hash for the ultimate balanced brunch spread.
- Warm Morning Beverages: Freshly brewed dark roast coffee, spiced chai tea lattes, or hot mulled apple cider.
Storage, Freezing & Reheating Instructions
- Refrigeration: Cool leftover casserole completely, cover tightly with foil or transfer squares to an airtight container, and refrigerate for up to 4 days.
- Oven Reheating (Best Texture): Cover squares with foil and warm in a 350°F (175°C) oven for 10 to 12 minutes to restore the crispy streusel topping and fluffy custard interior.
- Freezer Instructions: Slices can be wrapped individually in plastic wrap and aluminum foil, then frozen for up to 2 months. Thaw overnight in the fridge and reheat in the oven or toaster oven before serving.
Baked Pumpkin French Toast Casserole (Pecan Streusel)
Ingredients
Method
- Generously grease a 9×13-inch ceramic baking dish with butter. Cut the day-old brioche loaf into 1-inch cubes and scatter them evenly into the prepared dish.
- In a large mixing bowl, thoroughly whisk together the eggs, pure pumpkin puree, whole milk, heavy cream, maple syrup, vanilla extract, pumpkin pie spice, cinnamon, and sea salt until completely smooth, aromatic, and uniform.
- Pour the spiced custard evenly over the brioche cubes. Use a silicone spatula to gently press the bread down so every single piece absorbs the rich custard. Let rest for 15 minutes at room temperature (or cover tightly with foil and refrigerate overnight).
- In a medium bowl, mix together brown sugar, chopped pecans, flour, and cinnamon. Add cold cubed butter and work with your fingers or a pastry cutter until crumbly with pea-sized clumps.
- Preheat oven to 350°F (175°C). Scatter the pecan streusel evenly over the top of the soaked casserole. Bake uncovered for 40 to 45 minutes until the casserole is puffed, the edges are caramelized, and the center is set.
- Let rest for 10 minutes so the custard settles. Dust generously with powdered sugar and drizzle with warm pure maple syrup. Slice into large squares and serve warm with fresh berries!

Let us know how it was!Frequently Asked Questions
Can I make this casserole ahead of time?
Yes! In fact, overnight soaking makes it even tastier. Assemble the bread and custard, cover tightly with foil, and refrigerate for up to 24 hours. Add the pecan streusel right before placing in the oven.
What is the best bread for French toast casserole?
Brioche and challah are the absolute best choices because their high egg and butter content produces a rich, tender custard. Sourdough or French bread also work well if you prefer a less sweet base.
Can I make it nut-free?
Absolutely! Simply omit the pecans from the streusel or replace them with toasted rolled oats or pumpkin seeds (pepitas) for wonderful crunch without tree nuts.
