Proper Storage For Roasted Parmesan Creamed Onions

• Store leftover creamed onions in an airtight container in the refrigerator, where they’ll stay fresh for 3-4 days. Seal them tightly to keep all those amazing roasted flavors locked inside.
• When reheating, warm your onions gently in the oven at 350°F to preserve their creamy texture. Covering the dish with foil helps prevent drying out and keeps everything deliciously moist.
• If your creamed onions seem a bit dry after refrigeration, stir in a splash of cream or milk when reheating to restore their original silky consistency.
• Freeze portions in freezer-safe containers for up to one month. Thaw overnight in the refrigerator before gently rewarming to maintain the best flavor and texture.
