- When ready to bake, preheat your oven to 350°F (175°C).

Best Ways to Enjoy It
This casserole is best served warm and can be accompanied by a side of fresh fruit or a light salad for balance. A drizzle of maple syrup can add a delightful sweetness, and if you’re feeling indulgent, a dollop of sour cream or crème fraîche adds a creamy touch. Don’t forget a steaming cup of coffee or tea to wash it all down!
Storage and Reheating Tips
Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat, simply place individual portions in the microwave for 1-2 minutes or warm in the oven at 350°F (175°C) until heated through. If you plan to keep it longer, consider freezing portions in tightly wrapped foil for up to 2 months. Thaw in the fridge overnight before reheating!
Helpful Cooking Tips
- For an extra crunchy topping, add some breadcrumbs or crushed crackers on top before refrigerating.
- If you want to speed up prep time, use pre-cooked bacon or sausage.
- Let the casserole rest for a few minutes after baking. This will help it set and make serving easier.

Feel free to jazz it up! Try incorporating spinach or bell peppers for added veggies. Use a mix of cheeses, or swap the meat for something vegetarian like mushrooms or diced tomatoes. Flavored croissants, such as almond or chocolate, can also lead to an exciting dessert twist if you want a sweet version.
