This easy to make savory breakfast casserole is the perfect start to your weekend or holiday brunch gatherings! Chicken apple sausage, spinach, cheese, eggs and French bread are key ingredients in this delicious recipe!
Grease a 9x13 casserole dish and preheat oven to 350 degrees.
Brown the chicken apple sausage. While browning, butter one side of French bread slices (optional) and place in dish, buttered side up. I like to tear or cut the slices into 1/4 and then throw into dish (see photo in post).
When sausage is browned, remove from pan. Add olive oil to pan on medium heat. Add onion saute for 2-3 minutes. Then add minced garlic. Cook for one minute.
Remove from heat, add dry mustard, oregano, and fresh spinach. Mix well. Place back on heat just until spinach starts to wilt.
Spoon cooked sausage and spinach mixture over bread in pan.
Whisk 10 large eggs, milk or half and half, and salt and pepper in a bowl.
Pour over rest of ingredients in baking dish.
Top with grated cheese. Cover with foil and bake for 30 mins. Take foil off and bake for an additional 20 minutes.
Serve with salsa, sour cream or plain unsweetened Greek yogurt.
