Ingredients
- 4 large croissants
- 4 sausage patties
- 4 slices Colby Jack cheese
- 6 large eggs
- 1 tbsp Everything but the Bagel Seasoning (optional)
- 1 cup spinach
- 2 tbsp unsalted butter
- 3 tbsp milk
- 1/2 tsp salt
- 1/2 tsp black pepper
Instructions
- Step 1: Preheat the oven to 350°F and lightly grease a baking dish with nonstick spray.
- Step 2: In a medium mixing bowl, whisk together the eggs, milk, salt, and pepper until fully combined.
- Step 3: Heat 1 tablespoon of butter in a skillet over medium-high heat. Once the butter is hot, add the eggs and cook, stirring occasionally, until fully scrambled and cooked through.
- Step 4: Slice the croissants in half and arrange the bottom halves in the prepared baking dish.
- Step 5: Layer a handful of spinach on each croissant bottom, then spoon on the scrambled eggs. Top each with a slice of sausage and a slice of Colby Jack cheese.
- Step 6: Place the top halves of the croissants over the assembled layers.
- Step 7: Microwave the remaining 1 tablespoon of butter until melted. Brush the melted butter over the top of each croissant, then sprinkle with Everything but the Bagel Seasoning, if using.
- Step 8: Bake in the preheated oven for 10 minutes, or until the croissants are golden brown and the cheese is melted.
Tips & Variations
- Substitute spinach with kale or arugula for a different green flavor and texture.
- Use your favorite cheese like cheddar or Swiss instead of Colby Jack for a new taste.
- For a vegetarian version, replace sausage patties with sautéed mushrooms or plant-based sausage.
- To add extra flavor, spread a thin layer of Dijon mustard or mayonnaise on the croissant halves before assembling.
Storage
Store any leftover sandwiches in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 325°F for 10 minutes or until warmed through to keep the croissant crisp. Avoid microwaving to maintain texture, but you can cover loosely with a paper towel if microwaving is necessary.

FAQs
Can I make these sandwiches ahead of time?
Yes, you can assemble the sandwiches the night before and refrigerate them. Bake right before serving for the freshest taste.
Can I freeze the baked croissant breakfast sandwiches?
While you can freeze the assembled sandwiches before baking, the croissants may lose some flakiness after thawing. It’s best to wrap them tightly and freeze for up to 1 month. Reheat by baking until warmed through.

Instructions
