There’s nothing like a hot meal to start off the morning. I’ve always cherished the time we’ve spent as a family eating breakfast together. It’s also one of the reasons I love the holidays so much!

Can a breakfast bake be made ahead?

You can also make this Chicken Apple Sausage with Spinach Breakfast Bake ahead so you can sleep in! It can assembled the night before or made and baked immediately the day of. It’s even easy enough to let the kids make! When our kids were younger and I had to run around on Christmas Eve day, I’d put them in charge of making the Christmas breakfast overnight casserole. They loved being in charge of our special Christmas brunch, and I loved having one item checked off of my to-do list!

If assembling the whole casserole for baking, I’m often asked how far in advance can this be done. My answer is the day or night before! If this is done too far ahead, the eggs may begin to separate.

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!


  • 4 links (12-16 oz) chicken apple sausage, sautéed
  • 3/4 loaf of french bread, sliced thick and buttered(optional) on one side
  • 1 1/2 cups chopped onion
  • 2 tbsp olive oil
  • 1 clove garlic, minced
  • 1 tsp dry mustard
  • 1 tsp dried oregano
  • 3 cups fresh spinach, washed and drained
  • 10 large eggs
  • 2 cups milk or half and half
  • salt and pepper
  • 3 cups grated cheese any type (cheddar, colby-Jack, Swiss or a combination)


  • Grease a 9×13 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.


  • I usually purchase grocery store French Bread for this recipe. You may also use leftover rolls, thick sliced bread, any type. Artisan loaves also work well! 
  • If making ahead, assemble the casserole and cover with foil and place in refrigerator. When ready to bake, remove 30-45 minutes before baking and place on counter. Preheat oven and bake as directed.
