1. Prepare the Fish:
* Gently pat the fish fillets dry with paper towels. This is a crucial step to help the breading adhere properly.
* Place the fish on a clean cutting board. Using a sharp knife, cut the fillets into “stick” shapes, approximately 1 inch wide and 3-4 inches long. Try to keep them relatively uniform in size for even cooking.
* Place the fish sticks in a bowl, drizzle with the fresh lemon juice, and lightly season with a pinch of salt and pepper. Gently toss to coat. The lemon juice not only adds a subtle brightness but can also help firm up the fish slightly. Set aside for a few minutes while you prepare the breading station.

2. Set Up Your Breading Station:
This classic three-step breading process ensures maximum adhesion and crispiness. You’ll need three shallow dishes or pie plates.
* Dish 1 (Flour Dredge): In the first shallow dish, combine the all-purpose gluten-free flour, paprika, garlic powder, onion powder, 1/4 teaspoon salt, and 1/4 teaspoon black pepper. Whisk thoroughly to ensure the seasonings are evenly distributed.
* Dish 2 (Egg Wash): In the second shallow dish, crack the two large eggs. Add the tablespoon of water or almond milk and whisk vigorously until the yolks and whites are fully combined and slightly frothy.
* Dish 3 (Crispy Coating): In the third shallow dish, combine the gluten-free panko breadcrumbs, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and any optional additions like nutritional yeast or dried parsley. Mix well.

3. Bread the Fish Sticks:
Work with one fish stick at a time to ensure each one is perfectly coated. It’s helpful to use one hand for the dry ingredients (flour and breadcrumbs) and the other hand for the wet ingredients (egg wash) to prevent your fingers from becoming overly clumpy.
* Dredge in Flour: Take a fish stick and lightly coat it on all sides with the seasoned gluten-free flour mixture from Dish 1. Shake off any excess flour. This initial flour coating gives the egg wash something to cling to.
* Dip in Egg Wash: Transfer the floured fish stick to Dish 2 and dip it into the egg wash, ensuring it’s completely moistened. Allow any excess egg to drip off for a second or two.
* Coat with Panko: Immediately transfer the egg-washed fish stick to Dish 3, containing the gluten-free panko breadcrumbs. Press the breadcrumbs firmly onto all sides of the fish stick, ensuring a thick, even coating. This pressing action is key for a crispy crust that stays put.
* Set Aside: Place the breaded fish stick on a clean baking sheet lined with parchment paper or a wire rack. Repeat this process with all the remaining fish sticks, arranging them in a single layer without touching.

4. Cook the Fish Sticks (Choose Your Method):

*   **Option A: Baking (Healthier):**
    *   Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
    *   Arrange the breaded fish sticks in a single layer on the prepared baking sheet, ensuring they are not overcrowded (use two sheets if necessary). Overcrowding will steam the fish sticks instead of making them crispy.
    *   Lightly drizzle or spray the tops of the fish sticks with olive oil, avocado oil, or melted coconut oil. This helps them achieve a golden-brown color and extra crispiness.
    *   Bake for 15-20 minutes, flipping them gently halfway through, until they are golden brown, crispy, and the fish is cooked through (internal temperature of 145°F or 63°C). Cooking time may vary slightly depending on the thickness of your fish sticks and your oven's accuracy.

*   **Option B: Pan-Frying (Extra Crispy):**
    *   Place a large skillet (cast iron works wonderfully) over medium-high heat. Add enough oil to create a shallow layer, about 1/4 to 1/2 inch deep.
    *   Heat the oil until it shimmers or a small piece of breadcrumb dropped in sizzles immediately (around 350°F or 175°C). Don't let the oil smoke.
    *   Carefully place the breaded fish sticks into the hot oil in a single layer, being cautious not to overcrowd the pan. Work in batches if necessary.
    *   Fry for 2-4 minutes per side, until golden brown and crispy, and the fish is cooked through. The exact time will depend on the thickness of the fish and the oil temperature.
    *   Once cooked, remove the fish sticks from the skillet using a slotted spoon or tongs and transfer them to a wire rack lined with paper towels to drain any excess oil. The wire rack allows air to circulate, keeping the bottoms crispy. Season immediately with a tiny pinch of extra salt if desired, while they are still hot.

*   **Option C: Air Frying (Crispy with Less Oil):**
    *   Preheat your air fryer to 400°F (200°C).
    *   Lightly spray the air fryer basket with cooking oil.
    *   Arrange the breaded fish sticks in a single layer in the air fryer basket, ensuring there's space between them for air circulation. Work in batches if needed.
    *   Lightly spray the tops of the fish sticks with oil.
    *   Air fry for 10-12 minutes, flipping them halfway through, until golden brown, crispy, and cooked through.
