Brunch should feel like a soft landing, not a full-contact sport. This warm and spiced brunch bake is my go-to when I want the house to smell like cinnamon and vanilla and I want me to still be wearing pajamas when people start asking, “What’s for brunch?”

It is basically French toast’s more organized cousin. We cube a loaf of bread, soak it in a simple custard, and bake it until the top goes crisp and bronzed while the inside stays tender and custardy. The best part is you can prep it the night before, then bake it in the morning while you make coffee and pretend you totally have your life together.

Why It Works

  • Big comfort, low effort: It is hands-off once it hits the oven, and it feeds a group without you flipping individual slices at the stove.
  • Crisp edges, cozy center: A hot oven plus a buttery brown sugar swirl gives you those caramelized corners we all fight over.
  • Make-ahead friendly: An overnight soak means better texture and easier mornings.
  • Flexible flavor: Keep it classic or add orange zest, chopped apples, or toasted nuts depending on your mood and pantry.

Storage Tips

Fridge: Let leftovers cool, then cover the dish or transfer to an airtight container. Refrigerate for up to 4 days.

Reheat: For the best texture, warm slices on a sheet pan at 350°F for 8 to 12 minutes. Microwave works in a pinch, but the top will soften.

Freeze: Slice into portions, wrap tightly, and freeze up to 2 months. Thaw overnight in the fridge before reheating.

Pro tip: If the top looks a little sleepy after reheating, hit it with 1 to 2 minutes under the broiler and watch it like a hawk.

Common Questions

What kind of bread works best?

Brioche and challah are the dream team for a rich, tender center. French bread also works great for a slightly chewier bite. Slightly stale bread is your friend because it drinks up custard without turning to mush. If your loaf is super fresh, you can dry the cubes on a sheet pan at 300°F for 10 to 15 minutes, then cool before soaking.

Do I have to let it sit overnight?

No, but it helps. If you are short on time, let it soak while the oven preheats (and up to 30 minutes). Overnight gives you the most even, custardy texture. If it has been in the fridge overnight, letting it sit at room temperature for 20 to 30 minutes before baking can help it bake more evenly.

Can I make it dairy-free?

Yes. Use an unsweetened plant milk (full-fat oat is especially cozy here). Swap the butter for a dairy-free alternative. If your plant milk runs a little sweet, you can reduce the granulated sugar by 1 to 2 tbsp to keep things balanced.

How do I know it is done?

The center should look set, not sloshy. An instant-read thermometer in the middle should read 160 to 165°F (aim for 165°F for the most conservative food-safety target). If the top browns too fast, tent loosely with foil.

Can I add fruit or nuts?

Absolutely. Add 1 to 1 1/2 cups of diced apples or pears, or 1/2 cup toasted pecans or walnuts. If using very juicy fruit (like berries), scatter it on top halfway through baking to avoid a soggy center.

The first time I made a brunch casserole, I was trying to impress friends and also pretend I was not a little overwhelmed. I wanted the vibes of a fancy café without spending my whole morning at the stove. This bake became my answer. You do the work once, you get that cinnamon-vanilla “something good is happening” smell for free, and suddenly everyone is hovering around the oven like it is a fireplace. I call that a win.
