Can you marinade steak in fridge for 3 days without it going bad?

Yes, you can marinate steak in the fridge for up to 3 days without it going bad, provided it is kept at a safe temperature (below 40°F or 4°C). However, the texture and flavor may change if marinated for too long, especially if the marinade contains acidic ingredients like vinegar or citrus juice. It's best to monitor the marinade's acidity and adjust the marinating time accordingly for optimal results. Always ensure the steak is stored in a sealed container to prevent contamination.
