Ingredients

Scale

Sandwich Ingredients

  • 4 large croissants
  • 4 sausage patties
  • 4 slices Colby Jack cheese
  • 1 cup spinach

Egg Mixture

  • 6 large eggs
  • 3 tbsp milk
  • 1/2 tsp salt
  • 1/2 tsp black pepper

Other

  • 2 tbsp unsalted butter, divided
  • 1 tbsp Everything but the Bagel Seasoning (optional)

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 350°F (175°C) and lightly grease a baking dish with nonstick spray to prevent sticking during baking.
  2. Prepare Egg Mixture: In a medium bowl, whisk together the eggs, milk, salt, and black pepper until fully combined and smooth to ensure even cooking.
  3. Cook Scrambled Eggs: Heat 1 tablespoon of butter in a skillet over medium-high heat. Once melted and hot, pour in the egg mixture and cook, stirring occasionally to scramble, until the eggs are fully cooked and set. Remove from heat.
  4. Assemble Croissants: Slice each croissant in half horizontally and place the bottom halves evenly in the prepared baking dish.
  5. Layer Fillings: On each croissant bottom, layer a handful of fresh spinach, then spoon the scrambled eggs on top. Place one sausage patty and a slice of Colby Jack cheese over the eggs.
  6. Top Croissants: Cover each assembled sandwich with the top halves of the croissants, pressing gently to secure the layers.
  7. Butter and Season Tops: Melt the remaining 1 tablespoon of butter in the microwave. Brush this melted butter over the tops of each croissant, then sprinkle with Everything but the Bagel Seasoning for extra flavor and texture.
  8. Bake Sandwiches: Bake the croissant sandwiches in the preheated oven for 10 minutes, or until the croissants turn golden brown and the cheese inside has melted beautifully.

Notes

  • You can substitute croissants with English muffins or brioche buns if preferred.
  • For a vegetarian version, replace sausage patties with plant-based sausage or omit them entirely.
  • Everything but the Bagel Seasoning is optional but adds a delicious savory crunch.
  • Leftover sandwiches can be wrapped and refrigerated, then reheated in the oven or microwave.
  • Adding fresh tomatoes or avocado slices can add a fresh twist to the sandwich.
