    Tips for Cooking Keto Fish Dishes

    • Use healthy fats: Cooking fish in fats like butter, ghee, or avocado oil enhances the flavor and helps keep the fish moist.
    • Grill or bake for best results: Grilling adds a smoky flavor, while baking is great for even cooking without drying out the fish.
    • Avoid overcooking: Fish cooks quickly, so keep an eye on it to ensure it stays tender and flaky. A general rule is to cook fish for 10 minutes per inch of thickness.
    • Season generously: Fish can take on many flavors, so don’t be shy with seasonings like garlic, lemon, herbs, and spices.
    • Keep the skin on: When grilling or pan-frying, leave the skin on to help hold the fish together and add extra crispiness.

    Meal Prep and Storage Tips for Keto Fish Recipes

    Many keto fish recipes can be prepped ahead of time to make meal planning easier. Dishes like salmon patties or fish casseroles can be made in batches and stored in the freezer for later use. To retain the best texture, always store fish in an airtight container and reheat it gently to avoid drying it out.
