Chicken: Marinate for 2 to 4 hours, or overnight for maximum flavor penetration. Shrimp: Marinate for 30 minutes to 1 hour. Fish Fillets: Marinate for 30 minutes to 2 hours, depending on the thickness of the fillets. Scallops: Marinate for 30 minutes to 1 hour. Steak: Marinate for 2 to 4 hours to infuse the flavors into the meat and enhance tenderness, or up to 24 hours. Pork Chops: Marinate for 2 to 4 hours to tenderize and impart a burst of flavor, or up to 24 hours for maximum flavor. Tofu: Marinate for at least 30 minutes to 1 hour. Also, make sure to press it first so the tofu can soak up the lemony goodness! Remember, marination times can vary depending on the thickness and desired flavor intensity. Generally speaking, fish, veggies, and tofu are more delicate and shouldn’t be marinated for longer than about 4 hours. Steak, pork, lamb, chicken, and other land-animal proteins can be marinated for up to 24 hours with no negative effects.
