Step By Step Instructions On How To Make Jack In The Box Fish Sandwich

Step 1: Prepare The Fish

1. Pat the fish fillets dry with paper towels. This helps the coating stick better.

Step 2: Season The Flour

In a shallow bowl, mix:

1. 1 cup all-purpose flour
2. 1 teaspoon salt
3. ½ teaspoon black pepper
4. 1 teaspoon paprika

Stir well to combine.

Step 3: Set Up The Breading Station

Place:

1. The seasoned flour in one bowl
2. 1 cup buttermilk in a second bowl
3. 1 cup breadcrumbs (panko recommended) in a third bowl

Step 4: Coat The Fish

1. Dredge each fillet in the seasoned flour.
2. Dip it into the buttermilk.
3. Coat it fully in breadcrumbs, pressing gently so it sticks well.

Set aside on a plate.

Step 5: Fry The Fish

1. Heat oil in a deep pan to 350°F (175°C).
2. Carefully place the fillets in the hot oil.

Fry for 3–4 minutes per side, or until:

1. Golden brown
2. Crispy on the outside
3. Cooked through inside

Remove and place on paper towels to drain excess oil.

Step 6: Make the Tartar Sauce

1. In a small bowl, mix the following and stir well to chill for 10–15 minutes.

• ½ cup mayonnaise
• 1 tablespoon sweet pickle relish
• 1 teaspoon lemon juice
• ½ teaspoon sugar
• ¼ teaspoon garlic powder

Step 7: Toast The Buns

2. Place the crispy fish fillet on top.
3. Add shredded lettuce.
4. Cover with the top bun.

Serve immediately while warm and crispy.

• For a lighter version, air fry at 400°F for 10–12 minutes, flipping halfway.
