Reheat leftover gravy thoroughly on the stovetop or in the microwave until it reaches an internal temperature of 165°F (74°C). Consider adding a little broth or water if it's too thick, and season to taste.
Reusing gravy from a previous day's meal is perfectly safe and economical, provided you handle it correctly. Here's a step-by-step guide:
Storage: Ensure the gravy was properly stored in the refrigerator within two hours of cooking. It should be in an airtight container to prevent bacterial growth and absorption of other flavors.
Inspection: Before reheating, inspect the gravy for any signs of spoilage, such as an off odor, mold, or a slimy texture. If you notice any of these, discard the gravy immediately.
Reheating on the Stovetop: Pour the gravy into a saucepan. Heat over medium-low heat, stirring frequently to prevent scorching. Bring the gravy to a simmer and ensure it reaches an internal temperature of 165°F (74°C). Use a food thermometer to verify.
Reheating in the Microwave: Place the gravy in a microwave-safe dish. Cover loosely with a microwave-safe lid or plastic wrap (leaving a vent for steam). Heat in 1-minute intervals, stirring in between, until it reaches an internal temperature of 165°F (74°C).
Adjusting Consistency: If the gravy has thickened too much during refrigeration, add a little broth, water, or milk while reheating to achieve the desired consistency. Stir well to incorporate.
Seasoning: Taste the reheated gravy and adjust the seasoning as needed. You might want to add a pinch of salt, pepper, or other herbs and spices to brighten the flavor.
To prevent a skin from forming on the gravy while reheating, place a piece of plastic wrap directly on the surface of the gravy while it heats. Remove the plastic wrap before serving. This minimizes air exposure and keeps the surface moist.
