Tip: save now, cook later.Sweet Maple Sausage Breakfast Casserole is a cozy, comforting dish that combines the warm flavors of maple syrup, hearty sausage, and fluffy eggs all baked together into one delicious casserole. With little pockets of sweetness from the maple and the savory richness of sausage, it’s the perfect way to start a slow weekend morning.
I love making this casserole when friends or family come over because it’s so easy to prepare ahead of time and everyone always asks for seconds. The maple syrup adds just the right touch of sweetness without being overpowering, and the sausage gives it a nice, satisfying bite. I usually add a little bit of chopped onion and cheese to the mix, which takes it to the next level of yum.
My favorite way to serve this is right out of the oven, with a crisp side of fresh fruit or a simple green salad. It’s the kind of breakfast that feels like a warm hug and makes the whole kitchen smell amazing. Plus, it’s great leftovers for the next day, warmed up just as good as fresh. This casserole always brings a smile to my morning, and I hope it does the same for you!
Key Ingredients & Substitutions
Breakfast Sausage: Using mild or sweet sausage is great to balance the maple syrup’s sweetness. If you want less fat, try turkey sausage—but it might be less juicy.
Maple Syrup: Pure maple syrup gives a nice sweet flavor here. You can swap it with honey or agave syrup if you don’t have maple handy.
Bread: Day-old bread works best because it soaks up the egg mixture without getting soggy. Brioche is my favorite for its slight sweetness, but white or whole wheat bread works fine too.
Cheddar Cheese: Sharp cheddar gives a nice tang that balances the sweetness. You can try Monterey Jack or Colby for a milder taste.
Onion: Adds subtle flavor and texture. If you prefer, use green onions or skip them if you want a simpler taste.
How Do You Make Sure the Casserole Sets Well Without Getting Soggy?
The key is letting the bread absorb just enough liquid without falling apart. Here’s how I do it:
- Use day-old bread cut into cubes. It has less moisture and holds up better.
- After mixing everything, let the mixture sit for about 10 minutes before baking. This lets the bread soak up the egg and milk without getting too mushy.
- Bake at 350°F so the casserole cooks evenly and sets without drying out.
- Rest the casserole 5-10 minutes after baking; it firms up and is easier to cut.
Equipment You’ll Need
- 9×9-inch baking dish – perfect size for even baking and easy serving.
- Large skillet – to brown and cook the sausage evenly.
- Mixing bowl – big enough to whisk eggs, milk, and syrup without spilling.
- Whisk – helps blend eggs and liquids for a smooth mixture.
- Measuring cups and spoons – for accurate ingredient amounts.
- Rubber spatula or wooden spoon – for folding ingredients together gently.
Flavor Variations & Add-Ins
- Swap breakfast sausage with cooked bacon or ham for a smokier taste.
- Use pepper jack cheese instead of cheddar to add a mild spicy kick.
- Add diced bell peppers or sautéed mushrooms for extra veggies and texture.
- Stir in fresh herbs like thyme or rosemary for a fragrant, earthy note.

Sweet Maple Sausage Breakfast Casserole
Ingredients You’ll Need:
- 1 pound breakfast sausage (mild or sweet)
- 6 large eggs
- 1 cup whole milk
- ½ cup pure maple syrup
- 4 cups cubed bread (day-old white or brioche works well)
- 1 small onion, finely chopped
- 1 cup shredded cheddar cheese
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon dried sage (optional)
- 2 tablespoons butter (for greasing the pan)
- 2 green onions or chives, chopped (for garnish)
How Much Time Will You Need?
This casserole takes about 15 minutes to prep and around 45-50 minutes to bake. Plus, add about 5-10 minutes resting time before serving. Overall, plan for just over an hour from start to mouth-watering finish!
Step-by-Step Instructions:
1. Prepare Your Baking Dish and Sausage:
Preheat your oven to 350°F (175°C). Butter a 9×9 inch baking dish lightly so your casserole won’t stick. Next, in a skillet over medium heat, cook your sausage by breaking it up with a spatula until browned and fully cooked. Drain any extra fat and set aside.
2. Mix Your Egg and Liquid Base:
In a large bowl, whisk your eggs, whole milk, maple syrup, salt, pepper, and dried sage (if using) until everything is smoothly combined.
3. Combine All Ingredients:
Fold the cooked sausage, chopped onion, cubed bread, and shredded cheddar cheese into the egg mixture. Gently toss so the bread absorbs some liquid and the ingredients are well mixed.
4. Bake the Casserole:
Pour the mixture evenly into your prepared baking dish. Place it in your preheated oven and bake for 45-50 minutes until the center is set and the top turns golden brown.
5. Rest and Serve:
After baking, let the casserole rest for 5-10 minutes to firm up a bit. Sprinkle chopped green onions or chives on top for a fresh finish. Cut into squares, serve warm, and enjoy your delicious sweet maple sausage breakfast casserole!
Can I Use Frozen Sausage for This Recipe?
Yes! Just make sure to thaw the sausage completely before cooking. Thaw it overnight in the fridge or use the defrost setting on your microwave. This ensures even cooking and better texture.
Can I Prepare the Casserole the Night Before?
Absolutely! Assemble everything in the baking dish, cover tightly with foil, and refrigerate overnight. In the morning, bake as directed—add a few extra minutes if it’s coming straight from the fridge.
How Should I Store Leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat individual portions in the microwave or warm lightly in the oven until heated through.
Can I Make This Casserole Gluten-Free?
Yes! Use a gluten-free bread variety for the cubed bread, and double-check that your sausage is gluten-free. This way, you keep the delicious flavors without gluten worries.
