Overnight Pancake Sausage Casserole
This Overnight Pancake Sausage Casserole turns a lazy weekend morning into something you don’t need to rush through. It’s a cross between a giant fluffy pancake and a savory bread pudding, with breakfast sausage scattered through a tender, maple-sweet batter.

You can assemble it the night before and slide it into the oven while the coffee brews. Or bake it right away for a quick breakfast-for-dinner night. Either way, you get golden edges and a soft, custardy center with very little work.
Why This Casserole Works
The pancake batter bakes up airy and light, never dense, and the sausage stays savory with little crisp bits that peek through the top. A pour of maple syrup just before serving melts into the warm crumb, giving you that sweet-salty balance without any extra steps.
Leftovers hold their shape and reheat well, so a batch made on Sunday can feed a few weekdays. It’s the kind of dish that feels like a treat, but the actual cooking is almost hands-off.
Ingredients

- 1 lb breakfast sausage, casings removed if using links: I use mild turkey sausage, but spicy or maple sausage both work.
- 2 cups pancake mix: any brand you like, or a homemade dry mix if you prefer.
- 1 1/2 cups milk: whole or 2% gives the best richness.
- 2 large eggs
- 2 tbsp melted butter: plus a little extra for greasing the dish.
- 1/4 cup maple syrup: plus more for serving.
- 1/2 tsp ground cinnamon: (optional)
- Pinch of salt
Variations / Substitutions
- Swap the sausage: Turkey sausage, cooked crumbled bacon, or plant-based sausage crumbles all substitute 1:1.
- Add cheese: Fold 1 cup of shredded sharp cheddar into the batter for a savory edge.
- Go dairy-free: Use unsweetened almond milk and a dairy-free butter alternative; the texture will be a bit less rich but still tender.
- Boost the maple: Brush the top with a little extra maple syrup during the last 5 minutes of baking for a glossy finish.
- Make it with buttermilk: Replace the milk with buttermilk for a subtle tang and even fluffier crumb.

How to Make Overnight Pancake Sausage Casserole
Step 1: Brown the Sausage

In a large skillet over medium-high heat, cook the 1 lb sausage, breaking it into small crumbles with a wooden spoon. Cook until no pink remains, about 6 to 8 minutes. Transfer to a plate and set aside.
You want the pieces fairly small so they suspend evenly in the batter. Drain any excess fat if needed so the casserole doesn’t turn greasy.
Step 2: Whisk the Pancake Batter

In a large bowl, whisk together the 2 cups pancake mix, 1 1/2 cups milk, 2 large eggs, 2 tbsp melted butter, 1/4 cup maple syrup, 1/2 tsp cinnamon (if using), and a pinch of salt. Stir just until combined, a few small lumps are fine.
Overmixing at this stage makes the baked texture tough instead of tender, so stop as soon as everything comes together.
Step 3: Assemble the Casserole

Grease an 8-inch square baking dish with butter. Scatter half of the cooked sausage evenly across the bottom, then pour the pancake batter over it. Sprinkle the remaining sausage on top and gently press some of the crumbles into the batter so they don’t just float.
If you’re making this ahead, now is the time to cover the dish and refrigerate it overnight. The batter will thicken slightly, which helps it bake up with a nicer structure the next morning. If baking right away, move on to the next step.
Step 4: Bake the Casserole

Preheat your oven to 375°F (190°C). Bake the casserole uncovered for 35 to 40 minutes, until the top is deeply golden and the center is set. A toothpick inserted in the middle should come out clean or with a few moist crumbs clinging to it.
The casserole will puff during baking and then settle a little as it cools on the counter, that’s completely normal. Let it rest for at least 5 minutes before cutting so the squares hold their shape.
Step 5: Slice and Serve

Cut the casserole into 6 squares and drizzle generously with maple syrup. Serve warm while the syrup melts into every crevice.
A Few Notes Before You Start
- Use room temperature eggs and milk: Cold ingredients can make the batter seize a little, so let them sit on the counter for 15 minutes before mixing.
- Don’t peek during baking: Opening the oven door in the first 30 minutes can cause the casserole to deflate. Trust the timer and use the oven light instead.
- Pick the right dish: A glass or ceramic baking dish distributes heat more evenly and prevents the bottom from overbrowning compared to a dark metal pan.
- Brush for a glossy top: If you want a shinier crust, lightly brush the surface with melted butter or a little maple syrup 5 minutes before the bake is done.
Bake times by dish size:
| Pan size | Bake time |
|---|---|
| 8×8-inch | 35–40 mins |
| 9×9-inch | 30–35 mins |
| 9×13-inch (double batch) | 40–45 mins |
Storing Leftovers
- Refrigerate: Cooled casserole can be stored in an airtight container in the fridge for up to 4 days.
- Reheating: Individual squares reheat nicely in the microwave for 1 minute. For a whole casserole, cover with foil and warm in a 350°F oven for 15 to 20 minutes.
What to Serve With Pancake Sausage Casserole
A pile of fresh berries or a citrus salad cuts through the richness and wakes up the plate. A dollop of plain Greek yogurt adds a cool, tangy contrast that works next to the maple sweetness. And, of course, a big pot of hot coffee never hurts.
Frequently Asked Questions
Why did my casserole deflate after baking?
A sudden drop in temperature, like opening the oven door too early, or overbeating the eggs can cause it to collapse. Let it cool gradually on the counter after baking.
Can I make this dairy-free?
Yes. Swap the milk for unsweetened almond or oat milk and use a dairy-free butter substitute. The texture will be a little less rich but still soft and sliceable.
How do I reheat a whole casserole?
Cover the dish tightly with foil and reheat in a 350°F oven for 15 to 20 minutes, or until the center is hot. Individual portions are faster in the microwave.
