How to make Jack in the Box Fish Sandwich
The Jack in the Box Fish Sandwich is a seasonal menu item from Jack in the Box. It is usually offered around Lent (February–April) when many fast food chains promote fish-based options.
Ingredients:
For the Fish:
- 4 white fish fillets (Cod, Pollock, or Tilapia are great choices)
- 1 cup all-purpose flour
- 2 large eggs
- 1 cup panko breadcrumbs
- Salt to taste
- Pepper to taste
- Oil for frying (Canola or Vegetable oil works well)
For the Tartar Sauce:
- 1/2 cup mayonnaise
- 1 tablespoon pickle relish
- 1 teaspoon lemon juice
- 1/4 teaspoon onion powder
- Salt and pepper to taste
Additional:
- 4 hamburger buns, preferably bakery-style for that authentic touch
- Shredded lettuce
Instructions:
- Prepare the Tartar Sauce: In a small bowl, mix together mayonnaise, pickle relish, lemon juice, and onion powder. Season with salt and pepper to taste. Refrigerate until ready to use to let the flavors meld.
- Prepare the Fish: Begin by setting up a breading station: Place flour seasoned with salt and pepper in the first shallow dish. Beat the eggs in a second shallow dish. Place the panko breadcrumbs in a third shallow dish.
- Pat the fish fillets dry with paper towels. This helps the coating adhere better.
- Dredge each fillet in the flour, shaking off any excess. Dip into the beaten eggs, and finally, coat well with the panko breadcrumbs.
- In a large skillet, heat enough oil over medium-high heat to shallow fry the fish fillets. The oil is ready when a breadcrumb sizzles upon contact.
- Carefully place the breaded fish in the hot oil. Cook for 3-4 minutes on each side or until golden brown and cooked through. Transfer to a paper towel-lined plate to drain any excess oil.
- Toast the Buns: While the fish is cooking, split your buns and lightly toast them in a toaster oven or skillet over medium heat. Toasting the buns adds texture and keeps them from getting soggy.
- Assemble the Sandwich: Spread a generous amount of tartar sauce on both halves of each toasted bun.
- Place a layer of shredded lettuce on the bottom halves.
- Add the fried fish on top of the lettuce.
- Top with the other half of the bun and press down lightly.
Tips for the Perfect Fish Sandwich:
- Choosing the Fish: Opt for fillets that are about 1/2 inch thick for even cooking and have a good crust-to-fish ratio.
- Achieving the Best Crisp: Ensure your oil is hot enough before adding the fish to avoid soggy breading. However, watch the heat to ensure it doesn’t burn.
- Serving: These sandwiches are best enjoyed immediately while the fish is crisp and warm.
What to serve with
Pairing the perfect side dishes with your homemade Jack in the Box Fish Sandwich can elevate your dining experience. The combination of flavors and textures complements the crispy fish and creamy tartar sauce.
Classic French Fries
Why It Works: It’s hard to beat the classic combination of a sandwich and fries. To mimic the fast-food experience, opt for a crispy, golden version. Depending on your preference, you can air fry, bake, or deep-fry your fries.
Variation Tip: For an extra flavor kick, experiment with seasoning mixes, such as Cajun or garlic parmesan.
Coleslaw
Why It Works: The creamy, crunchy texture of coleslaw serves as the perfect counterbalance to the tender fish and soft bun.
Preparation Tip: For a quick homemade coleslaw, mix shredded cabbage and carrots with a dressing of mayonnaise, vinegar, a pinch of sugar, salt, and pepper. Let it chill for at least 30 minutes before serving.
Sweet Potato Fries
Why It Works: Sweet potato fries offer a delightful sweet and savory contrast to the Jack in the Box Fish Sandwich. Their rich flavor and additional nutrition make them a popular choice.
Serving Suggestion: Pair with a small dish of honey mustard or aioli for dipping.
Onion Rings
Why It Works: The crispy, golden breading of onion rings and their savory sweetness pair excellently with the fish sandwich, adding another layer of texture.
Cooking Tip: For extra crunchy onion rings, double dip in batter and breadcrumbs before frying.
Garden Salad
Why It Works: A fresh garden salad with a simple vinaigrette can lighten the meal, offering a refreshing contrast to the deep-fried elements.
Ingredient Suggestions: For color and crunch, use a mix of greens, cherry tomatoes, cucumbers, and red onions.
Pickles
Why It Works: The sharp tang and crunch of pickles cut through the richness of the fish and tartar sauce, refreshing your palate.
Serving Suggestion: Offer a variety of pickle slices or spears on the side for added flavor and texture.
Soup
Why It Works: A light soup, such as a classic tomato or a seafood chowder, can add warmth and variety to your meal.
Preparation Note: Choose a soup that complements, rather than overwhelms, the main flavors of the fish sandwich.
