Casserole base

• 10 12 cups cubed brioche or challah (about 1 lb / 450 g ). Use day-old bread.

Streusel topping

Serving extras

Cooking Method

I love making an Overnight French Toast Casserole . I made it for my messy family brunch. Oh my gosh, friends fought over the streusel.

This version nods to the French Toast Casserole - Belly vibe. It uses brioche or challah for that soft, custardy bite.

Prep Steps

Prep well. Cube one loaf into 1 1.5 inch pieces. Spread on a sheet and air-dry an hour. Or toast at 300° F / 150° C for 8– 10 minutes .

Whisk eggs, milk, cream, sugar, vanilla, cinnamon, and salt. Pour over bread in the dish. Press gently so the bread soaks evenly.

Safety reminder: cook eggs fully. Aim for an internal temp of 160– 165° F / 71– 74° C .

Time saving tip: Cube bread the night before. Make the streusel earlier. Store in the fridge. That’s a real make-ahead French toast casserole win.

step-by-step Process

1. Grease a 9x13 pan and add bread cubes.
2. Pour custard evenly. Press so liquid rises to top layer.
3. Cover and chill 4– 12 hours (overnight is best).
4. Sprinkle brown sugar pecan streusel topping.
5. Preheat oven to 350° F / 175° C and bake 45– 55 minutes .
6. Check doneness: knife comes out mostly clean. Streusel must be golden.

Visual cues matter. The center should feel set, not soupy. The top should be golden, with caramelized edges. If the top darkens too fast, tent loosely with foil for the last 10 15 minutes .

Pro Tips

Use day-old brioche or challah. It soaks without turning gummy. For a quicker version, soak 30– 60 minutes at room temp.

Expert trick: dot melted butter on top before baking. It makes the top glossy and crisp. Another trick: pulse streusel briefly in a food processor for even crumbs.

Avoid these mistakes: too-wet bread or too-short bake. Both ruin texture. Don’t skip the rest; it’s what makes it custardy.

make-ahead option: assemble, cover, and chill up to 12 hours . Bake next morning. Serve with maple syrup and berries.

Honestly, it’s perfect for holiday brunch, whether you call it Pumpkin French Toast Casserole or a Challah bread pudding casserole.

Frequently Asked Questions

What is French Toast Casserole - Belly and how is it different from regular French toast?

French Toast Casserole - Belly is a baked, custardy version of French toast made from cubes of brioche or challah soaked in a vanilla-cinnamon egg custard and finished with a buttery brown-sugar-pecan streusel.

Unlike individual slices fried in a pan, the casserole is assembled in a dish, soaked (often overnight) so the center becomes custardy, and baked to feed a crowd think holiday brunch vibes rather than a quick weekday fry-up.

How long should I soak the bread can I speed up the process?

For best texture, refrigerate the assembled casserole for 4 12 hours (overnight is ideal) so the custard fully penetrates the bread; this yields a custardy interior and crisp streusel.

If you're short on time, a 30 60 minute room-temperature soak will work toast the cubes briefly (300°F / 150°C for 8 10 minutes) beforehand to help them absorb without going gummy.

Can I make French Toast Casserole - Belly ahead of time, freeze it, or reheat leftovers?

Yes assemble the casserole and refrigerate up to 24 hours before baking (cover tightly); assembled but unbaked can also be frozen for about 1 month thaw overnight in the fridge then bake as directed.

Baked leftovers freeze well for 2 3 months; reheat individual portions in a 350°F oven (covered) until warmed through, or microwave for a quick single serving, then crisp the streusel briefly under a broiler if needed.

What are the quick tricks to avoid a soggy center or an overbrowned top?

Use day-old or slightly dried bread and maintain a good custard-to-bread ratio (the recipe’s approx. 8 eggs for ~10 12 cups of bread is a solid guide); the custard should come up near but not completely cover the top layer.

Bake at 350°F and test doneness with a knife (it should come out mostly clean) or aim for an internal temperature of 160 165°F; tent with foil if the streusel is browning too quickly and let the casserole rest 10 15 minutes before cutting.

What are easy variations, substitutions, and should I worry about nutrition?

Try berry-lemon, apple-spice, or a boozy maple twist (add 2 tbsp bourbon) for simple variations; swap nuts for seeds or omit for allergies. For lighter or dairy-free options use lower-fat milk, reduce cream, or use full-fat oat/soy milk and vegan butter; gluten-free loaves work but texture may differ.

Nutritionally, a serving is roughly 420 kcal in this form reduce calories by trimming sugar and cream or serving smaller portions, and remember to account for toppings like syrup and powdered sugar.
