A quick and easy breakfast casserole made with turkey sausage, eggs, spinach, and cheese. Perfect for brunch or a crowd-pleasing potluck dish.

Ingredients

Scale
  • 1 lb turkey breakfast sausage
  • 10 large eggs
  • 1 ½ cups low-fat milk
  • 1 cup low-fat cottage cheese
  • 1 tsp Dijon mustard
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ tsp garlic powder
  • 3 cups frozen spinach, thawed and squeezed dry
  • 1 red bell pepper, diced
  • ½ cup diced onion
  • 4 cups cubed whole wheat bread
  • 1 ½ cups shredded reduced-fat cheddar cheese
  • ½ cup shredded mozzarella

Instructions

  1. Preheat oven to 350°F (175°C). Spray a 9×13 baking dish with cooking spray.
  2. Cook turkey sausage in a large skillet over medium-high heat, breaking it up, until browned and cooked through (6-8 minutes). Transfer to a plate lined with paper towels.
  3. Dice red bell pepper and onion into small pieces. Squeeze thawed spinach dry.
  4. In a large bowl, whisk together eggs, milk, cottage cheese, Dijon mustard, salt, pepper, and garlic powder until smooth and slightly frothy.
  5. Spread cubed bread evenly in the prepared dish. Top with cooked sausage, bell pepper, onion, and spinach. Sprinkle both cheeses over the top. Pour egg mixture evenly over everything, pressing down gently with a fork.
  6. Let rest for 10-15 minutes if time allows.
  7. Bake for 35-40 minutes, until golden brown on top and set in the center (knife inserted in middle comes out clean). If top browns too quickly, tent with foil.
  8. Let cool for 5-10 minutes before slicing and serving.

Notes

Squeeze spinach thoroughly to avoid a watery casserole. Toasting bread cubes before assembling adds extra texture. Letting the casserole rest before baking helps the bread absorb the egg mixture. Make ahead by assembling the night before and refrigerating; add 10 minutes to baking time.
