Ingredients

Scale
  • 1 pound breakfast sausage (spicy pork or mild)
  • 8 large eggs, room temperature
  • 2 cups whole milk or 2%, or almond/oat milk for dairy-free
  • 2 cups shredded sharp cheddar cheese or cheddar-mozzarella blend
  • 6 cups French bread or baguette, cubed into 1-inch pieces (day-old bread preferred)
  • 1 small yellow or white onion, finely chopped
  • 2 cloves garlic, minced
  • Salt and freshly ground black pepper to taste
  • 1 teaspoon dried thyme or Italian seasoning
  • 1 tablespoon butter or oil for cooking
  • Optional: pinch of red pepper flakes, fresh parsley for garnish

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Heat butter or oil in a large skillet over medium heat. Add sausage, breaking it up, and cook until browned and no longer pink, about 7-8 minutes. Drain excess fat if needed.
  3. Add chopped onion and minced garlic to the skillet with sausage. Cook 3-4 minutes until onions are translucent. Remove from heat.
  4. Spread cubed bread evenly in the greased baking dish.
  5. In a large bowl, whisk together eggs, milk, dried thyme or Italian seasoning, salt, and pepper until frothy.
  6. Stir cooked sausage, onions, and garlic into the egg mixture. Pour evenly over bread cubes in the baking dish. Press lightly to help bread absorb custard.
  7. Sprinkle shredded cheese evenly over the top.
  8. If time allows, cover with foil and refrigerate 30 minutes to 1 hour to soak. Otherwise, bake immediately.
  9. Bake uncovered for 45-50 minutes until eggs are set and top is golden brown. A knife inserted should come out clean.
  10. Let cool 5-10 minutes before slicing. Garnish with fresh parsley if desired and serve warm.

Notes

Use day-old bread to prevent sogginess. Refrigerate assembled casserole for at least 30 minutes if possible to allow bread to soak custard fully. Drain excess sausage fat to avoid greasiness. Cover with foil halfway through baking if edges brown too quickly. For a crispier top, broil for last 2-3 minutes watching carefully. Add extra 1/4 cup milk if casserole seems dry next time.
