Ingredients
4 large croissants, sliced in half
2 cups fresh spinach, chopped
1 cup sweet corn kernels (fresh, frozen, or canned and drained)
1 cup shredded mozzarella or cheddar cheese
2 tablespoons cream cheese, softened
1 tablespoon butter
1 teaspoon garlic, minced
1/2 teaspoon onion powder
Salt, to taste
Black pepper, to taste
1 teaspoon Italian seasoning (optional)
Fresh parsley, chopped, for garnish (optional)
Instructions
Melt the butter in a skillet over medium heat.
Sauté the minced garlic for about 30 seconds until fragrant.
Add the spinach and cook until wilted.
Stir in the corn and cook for 2–3 minutes until heated through.
Mix in the cream cheese until melted and evenly coats the vegetables.
Season with onion powder, salt, black pepper, and Italian seasoning if using.
Slice the croissants in half and lightly toast if desired.
Spoon the spinach and corn mixture onto the bottom half of each croissant.
Sprinkle the shredded cheese over the filling.
Close the sandwiches and bake or air fry for 3–5 minutes until the cheese melts and the croissants are warm and crisp.
Garnish with fresh parsley if desired and serve immediately.
Notes
Thaw and squeeze frozen spinach well before using to prevent a watery filling.
Mozzarella, cheddar, Havarti, Swiss, feta, or goat cheese all work well.
Add mushrooms, roasted red peppers, caramelized onions, or pesto for extra flavor.
Store the filling in an airtight container in the refrigerator for up to 3 days.
Keep croissants separate until ready to assemble for the best texture.
Reheat assembled sandwiches in a 325°F (165°C) oven or air fryer for 4–5 minutes.
