The best egg substitutes for coating fish before breading

[MASTERBAKER]

The best egg substitutes for coating fish before breading are buttermilk, mayonnaise, Dijon mustard, yogurt, or a flour-and-water slurry. These alternatives act as effective binders, ensuring panko or breadcrumbs adhere tightly for a crispy finish, especially when using a two-step dredging method. [1, 2, 3, 4, 5]
Top Egg Substitutes for Fish Breading:

• Mayonnaise (or Vegan Mayo): Provides a thick, creamy coating that holds heavy breadcrumbs very well.
• Buttermilk: Offers superior adhesion to egg and adds flavor.
• Plain Greek Yogurt: An excellent thick binder that works perfectly with Italian breadcrumbs or cornstarch.
• Dijon Mustard: Creates a thin, tangy, and secure coating, often paired with cream.
• Flour and Water Slurry: A simple \(1:1\) mix of flour and water (or milk) to create a thick, sticky liquid.
• Aquafaba: The liquid from a can of chickpeas acts similarly to egg whites.
• Melted Butter: Best for light coatings or baked fish, providing a rich flavor. [1, 2, 3, 4, 5, 6, 7]

How to Ensure Success:

1. Dredge First: Lightly coat the fish in plain flour, cornstarch, or spices first to create a dry base for the binder to stick to.
2. Use Oil/Butter: Spray or brush the fish with oil or melted butter before applying crumbs if not using a wet binder.
3. Chill: After breading, letting the fish sit in the fridge for 30–60 minutes helps the coating set and stick during cooking. [1, 2, 3, 4, 5]

For the best results, I'd suggest letting me know:

• How you plan to cook it (fried, baked, or air-fried)?
• What kind of breading are you using (panko, breadcrumbs, crackers)?

I can suggest the exact best substitute for your method.
