Step 8 – Remove the casserole from the oven. Let it rest for 10-15 minutes and then it’s ready to serve with your favorite toppings and enjoy.

Recipe Tips

Combining Ingredients – We like to heat the sausage mixture up before adding to the egg mixture. This ensures everything is cooked thoroughly before layering in the baking dish.
Cooking Time – Cooking time will vary based on your oven and the casserole. The center will no longer be jiggly when the casserole is fully cooked.
