Overnight Sausage Pancake Breakfast Casserole layers fluffy pancakes with savory breakfast sausage and a lightly sweet maple egg custard. As the casserole rests overnight, the pancakes absorb the custard while keeping enough structure to create soft layers with crisp, golden edges after baking.
This 9 × 13-inch breakfast casserole is designed to be assembled the night before and baked the next morning. It works well for holidays, brunches, and weekends when you want most of the preparation finished ahead of time.
Why This Recipe Works
- Overnight soaking flavors the pancakes throughout. The egg mixture has time to absorb into the pancake layers instead of remaining mostly on the bottom of the dish.
- Cooked sausage adds savory contrast. Its saltiness balances the maple syrup and naturally sweet pancakes.
- A combination of milk and cream creates a tender custard. Whole milk keeps the casserole from becoming overly rich, while a little heavy cream adds body.
- Slightly dry pancakes hold their shape better. Day-old or cooled pancakes absorb the custard without immediately turning mushy.
- Uncovering the casserole near the end creates crisp edges. The covered baking stage sets the center, while the uncovered finish browns the top.
Equipment Needed

- Rubber spatula or wooden spoon
- Aluminum foil
- Instant-read thermometer
Ingredients List
For the Casserole
- 1 pound (454 g) breakfast sausage, casings removed if necessary
- 12 medium prepared pancakes, about 4 inches (10 cm) wide, approximately 18 ounces (510 g) total, cooled and cut into quarters
- 8 large eggs (about 400 g without shells)
- 2 cups (480 mL) whole milk
- ½ cup (120 mL) heavy cream
- ⅓ cup (80 mL) pure maple syrup
- 2 tablespoons (28 g) packed light brown sugar
- 1 teaspoon (5 mL) pure vanilla extract
- 1 teaspoon (about 2.5 g) ground cinnamon
- ¼ teaspoon (about 0.5 g) ground nutmeg
- ¼ teaspoon (about 1.5 g) kosher salt
- 1 tablespoon (14 g) unsalted butter, softened, for greasing the baking dish
For Serving
- ¼ cup (60 mL) pure maple syrup, optional, for drizzling
- 2 tablespoons (14 g) powdered sugar, optional, for dusting
Ingredient Notes and Substitutions
- Prepared Pancakes: Cooled homemade or store-bought pancakes both work. Pancakes that are several hours old or a day old absorb the custard especially well because their surfaces are slightly drier. Very thin crepe-style pancakes are not recommended because they can become too soft after soaking.
- Breakfast Sausage: Pork breakfast sausage adds savory flavor and enough fat to keep the filling moist. Turkey breakfast sausage can be substituted, but it is usually leaner and may have a slightly drier texture. Cook either variety fully before assembling the casserole.
- Whole Milk: Whole milk forms the base of the egg custard while keeping it lighter than an all-cream mixture. Two-percent milk can be substituted, although the custard will be slightly less rich.
- Heavy Cream: Heavy cream gives the custard a smooth, tender texture. Half-and-half can replace it in the same amount, though the casserole will be slightly lighter.
- Maple Syrup: Pure maple syrup provides sweetness and maple flavor without making the casserole excessively sugary. Pancake syrup can be used in a pinch, but its flavor and sweetness vary considerably from pure maple syrup.
Step-by-Step Instructions
1. Cook the Sausage
Heat a large skillet over medium-high heat.
Add the breakfast sausage and cook for 7–9 minutes, breaking it into small crumbles with a wooden spoon or spatula.
Continue cooking until no pink remains and the sausage reaches an internal temperature of 160°F (71°C) for pork sausage or 165°F (74°C) for poultry sausage.
Drain off excess grease and let the sausage cool for about 5 minutes.
2. Prepare the Baking Dish
Coat the inside of a 9 × 13-inch baking dish with the softened butter.
Cut each cooled pancake into quarters.
Arrange approximately half of the pancake pieces across the bottom of the dish, overlapping them slightly where needed.
3. Add the Sausage Layer
Scatter half of the cooked sausage evenly over the first pancake layer.
Arrange the remaining pancake pieces over the sausage, then finish with the remaining sausage.
Keep the layers relatively even so each serving gets a similar amount of pancake and meat.
4. Make the Maple Egg Custard
In a large mixing bowl, whisk the eggs until the yolks and whites are fully combined.
Add the whole milk, heavy cream, ⅓ cup (80 mL) maple syrup, brown sugar, vanilla extract, cinnamon, nutmeg, and kosher salt.
Whisk until the sugar has mostly dissolved and the mixture looks uniform.
5. Add the Custard
Slowly pour the egg mixture evenly over the pancake and sausage layers.
Press the top pancake pieces gently into the liquid with a spatula so they begin absorbing the custard.
Do not mash the layers together; the goal is simply to moisten the exposed pancake surfaces.
6. Refrigerate Overnight
Cover the baking dish tightly with aluminum foil.
Refrigerate for at least 8 hours and up to 12 hours.
During this time, the pancakes will absorb much of the custard. The casserole should look moist but not flooded with liquid when you check it the next morning.
7. Prepare for Baking
Remove the casserole from the refrigerator and let it stand at room temperature for 10 minutes while the oven preheats.
Preheat the oven to 350°F (175°C).
Keep the baking dish covered with foil during the initial baking stage.
8. Bake Covered
Place the casserole on the center oven rack.
Bake, covered, for 30 minutes.
The edges should begin to set, while the center may still look slightly soft.
9. Finish Baking Uncovered
Carefully remove the foil.
Continue baking for another 15–20 minutes, until the top is lightly golden and the center looks set rather than liquid.
The casserole should reach at least 160°F (71°C) in the center because it contains eggs. If the middle is still loose, continue baking in 5-minute increments.
10. Rest Before Serving
Remove the casserole from the oven and let it rest for 10 minutes.
The custard will continue to set slightly as it cools, making the casserole easier to cut into neat portions.
11. Garnish and Serve
Cut the casserole into 8 portions.
If desired, dust lightly with powdered sugar and drizzle with the optional maple syrup just before serving.
Serve warm.
Storage, Freezing, and Make-Ahead Instructions
- Refrigeration: Cool leftovers slightly, then transfer them to an airtight container or cover the baking dish tightly. Refrigerate within 2 hours of baking and store for up to 3–4 days. Keep additional maple syrup separate until serving so the casserole does not become soggy.
- Freezing: The baked casserole can be frozen in individual portions. Allow it to cool completely, then wrap portions tightly and place them in a freezer-safe container or bag. Freeze for up to 2 months. The pancakes may become slightly softer after freezing and thawing, but the casserole will still reheat well.
- Thawing and Reheating: Thaw frozen portions overnight in the refrigerator. Reheat in a covered baking dish at 325°F (165°C) for approximately 15–20 minutes, or until the center reaches 165°F (74°C). Individual portions can also be microwaved in short intervals until hot throughout.
- Make-Ahead Preparation: This casserole is specifically designed for overnight preparation. Assemble it completely, cover tightly, and refrigerate for 8–12 hours before baking. Do not leave the egg-based casserole at room temperature overnight. For longer make-ahead preparation, cook the sausage and pancakes up to 2 days in advance. Refrigerate them separately, then assemble the casserole the evening before baking.
FAQ
Can I make Overnight Sausage Pancake Breakfast Casserole with frozen pancakes?
Yes. Thaw the pancakes completely before assembling the casserole. If they feel damp after thawing, let them sit uncovered for a few minutes so excess surface moisture can evaporate before layering.
Can I use maple-flavored sausage?
Yes. Maple breakfast sausage pairs naturally with the maple custard, but it will make the finished casserole sweeter. You may want to reduce the brown sugar slightly if the sausage is noticeably sweet.
Why is my breakfast casserole soggy in the middle?
The casserole may be underbaked, or the pancakes may have been unusually moist before assembly. Continue baking until the center is set and reaches at least 160°F (71°C). Letting it rest for 10 minutes before cutting also helps the custard firm.
Can I prepare this casserole without heavy cream?
Yes. Replace the ½ cup (120 mL) heavy cream with an equal amount of whole milk. The casserole will be slightly lighter and less rich but will still set properly.
Can I add cheese?
Yes. For a more savory version, sprinkle up to 1 cup (113 g) shredded cheddar between the pancake and sausage layers. The cheese adds richness and makes the casserole less dessert-like while still pairing well with maple syrup.
