You’ll place your cooked sausage over the French Bread pieces then start to prepare the egg mixture that gets poured over the breakfast casserole. It’s best to use a large mixing bowl.
Once you’ve added your seasonings and pesto to the eggs, whisk until well beaten. Pour over bread and sausage layer.
Top with ground Parmesan Cheese, quartered cherry tomatoes and green onions.
Top with lots of shredded Mozzarella Cheese and it’s time to bake. Bake at 350 degrees F. for about an hour or until eggs are set and bread starts to brown.
Remove breakfast casserole from oven and garnish with finely sliced fresh basil. Let cool for about 5 minutes then cut into squares and serve.
