Capturing the elegance of a European bakery in every bite, these savory croissants will fill your kitchen with incredible aromas. Each buttery, flaky pastry is filled with a flavorful trio of earthy spinach, white onion, and cheese. Pre-proofed and brushed with egg, these croissants store in the freezer and need only 30 minutes to thaw before baking. Bake a few at a time for a gourmet breakfast or serve them all on a platter for an elaborate but effortless brunch.
