Substitutions and Variations
- Ground Pork Sausage - for this recipe I used Jimmy Dean sausage. You can substitute any other breakfast sausage; just make sure it's a breakfast sausage. Or you can try ground beef or diced ham.
- Cheeses - I used mild cheddar cheese and Parmesan cheese. You can substitute your favorite like Swiss or Monterey Jack would be great. I do think the Parmesan cheese adds a nice flavor to the overall taste of the casserole.
- Green Onions - are for garnish. You can leave them out if you prefer.
- Vegetables: Add a few vegetables like shredded zucchini or chopped peppers. Please Note: If you do add more vegetables or meats to this casserole, the cooking time will increase.

Step 1: In a sturdy skillet, cook the sausage for approximately 10 minutes, ensuring it's crumbled as it cooks. Once done, remove from the skillet and drain off any excess fat.
Step 2: Transfer the cooked sausage to a mixing bowl, then mix in the Parmesan cheese, sliced green onions, and croissant pieces. Spread the mixture evenly in a 13x9 baking dish that has been coated with non-stick baking spray.
Step 3: In another bowl, whisk together the eggs, milk, and heavy cream. Then, pour this mixture over the sausage mixture.
Step 4: Cover the dish and refrigerate for 8 hours or overnight to allow the flavors to meld.
Step 5: The following morning, let the casserole sit at room temperature for 30 minutes. Sprinkle with shredded cheddar, bake at 350°F for 45 minutes, then allow it to rest for 10 minutes before serving.
Insider Tips from My Kitchen to Yours
✔️ DO let a glass casserole dish sit on the counter for about 30 minutes before baking so it can warm up gradually and avoid sudden temperature changes.
❌ DO NOT skip the overnight soak, since the croissants need time to absorb the egg mixture or the casserole won’t bake up as soft and flavorful.
Storage & Serving Tips
Refrigerate: Store leftovers covered in the refrigerator for up to 3 days.
Freezer: Freeze baked and cooled portions in an airtight container for up to 2 months. Thaw overnight in the refrigerator before reheating.
Serving Tips: Reheat individual servings in the microwave or warm larger portions in the oven until heated through.

A breakfast casserole is done when a toothpick or skewer inserted into the center comes out clean, not wet. You can also check the internal temperature with an instant-read thermometer. When it reaches 160°F, the eggs are fully cooked and the casserole is ready.
You don’t have to prep it overnight. While letting it sit in the refrigerator helps the croissants soak up the egg mixture and improves the texture, you can assemble and bake it right away if you’re short on time. The casserole will still turn out delicious, just slightly less custardy.
Yes. You can use day-old bread, rolls, or even French bread, but the texture will be slightly different from using croissants.
You can freeze a cooked breakfast casserole for up to 2 months. Wrap it tightly in aluminum foil or store it in an airtight container. Allow the casserole to thaw overnight in the refrigerator. Reheat in the oven or microwave until warmed through.
