What is the Whataburger Spicy Chicken Sandwich?

At its core, the Whataburger Spicy Chicken Sandwich features a crispy fried chicken thigh marinated in buttermilk and Sriracha. It’s served on a toasted bun, topped with spicy mayo, lettuce, and tomatoes. This combination showcases a delightful contrast between the crunchy, spicy chicken and the cool, creamy toppings.

Why This Recipe Works

Creating a homemade version of this spicy delight involves careful thought and attention to detail. Here are four reasons why this recipe is a winner:

1. Flavor Explosion

The blend of spices in the marinade gives the chicken a potent kick while keeping it tender. The Sriracha in the buttermilk marinade and the spicy mayo work together to create layers of flavor.

2. Texture Contrast

Fried chicken brings a satisfying crunch. The toasted bun adds another layer of texture. It’s a delightful crunch with each bite, enhanced further by the crisp lettuce and juicy tomatoes.

3. Customizable

Whether you like it extra spicy or prefer to dial it down, this recipe allows for enough wiggle room to make it suit your taste. You can also experiment with toppings, adding jalapeños or a slice of cheese for a cheesy extra.

4. Homemade Goodness

There’s something refreshing about making food from scratch. You know exactly what goes into your meal, and you can take pride in preparing it yourself. Plus, there’s a satisfaction that comes with mastering a beloved dish.

How To Make This Whataburger Spicy Chicken Sandwich?

Now that we’ve gathered our ingredients, let’s put it all together in the kitchen. Follow these simple steps:

Step 1: Marinate the Chicken

In a bowl, combine the buttermilk, Sriracha, salt, black pepper, and garlic powder. Whisk it well. Place the chicken thighs in this mixture, ensuring they’re fully coated. Cover it and let it marinate in the fridge for at least 1 hour, ideally overnight for deeper flavor.

Step 2: Prepare the Flour Mixture

In another bowl, mix the flour, cornstarch, smoked paprika, salt, black pepper, garlic powder, and cayenne. Stir until combined. This mixture will create the crispy coating that we all love.

Step 3: Heat the Oil

In a large pan or deep fryer, heat oil over medium-high heat. Aim for about 350°F. A good way to test if the oil is ready is to drop a small piece of flour mixture into it. If it sizzles, you’re good to go.

Step 4: Bread the Chicken

Take the marinated chicken out of the buttermilk mixture, allowing excess to drip off. Dredge each piece in the flour mixture until fully coated.

Step 5: Fry the Chicken

Carefully place the breaded chicken in the hot oil. Fry for 4-6 minutes on each side, or until the chicken is golden and cooked through (internal temperature of 165°F). Remove and place on paper towels to drain excess oil.

Step 6: Make the Spicy Mayo

In a small bowl, combine mayonnaise, lemon juice, Sriracha, and dill pickle relish. Mix until smooth. Adjust the spiciness by adding extra Sriracha.

Step 7: Assemble the Sandwich

On a toasted bun, spread a generous layer of spicy mayo. Place the crispy chicken thigh on top and add lettuce, tomato, and pickles according to your preference. Top it with the other half of the bun and there you have it—your very own Whataburger Spicy Chicken Sandwich!

Tips & Tricks

Here are a few tips to ensure your sandwich shines:

  • Choose Thighs Over Breasts: Chicken thighs tend to be juicier and more flavorful than breasts, which can dry out easily.
  • Let the Chicken Rest: After frying, allow the chicken to rest for a couple of minutes. This keeps it juicy and flavorful.
  • Customize Spice Levels: Adjust the amount of Sriracha in both the marinade and spicy mayo to suit your heat tolerance.
  • Double Batch for Meal Prep: Make a double batch of fried chicken. It’s perfect for sandwiches throughout the week and can be kept warm in the oven.
  • Use Fresh Ingredients: The quality of your vegetables plays a big role. Fresh lettuce, ripe tomatoes, and crisp pickles make your sandwich pop.

Nutrition Information

While enjoying your sandwich, it’s good to keep an eye on nutrition. A typical serving may have roughly:

  • Calories: 600-700 (depending on toppings and portions)
  • Protein: 30g
  • Carbohydrates: 60g
  • Fat: 30g
  • Fiber: 2g

These numbers can vary. Adjust based on ingredients and side dishes.

How Do You Store The Leftovers?

If you find yourself with leftovers (which can be rare with this sandwich), it’s essential to store them properly. Keep the chicken and toppings separate to maintain texture. Wrap the chicken tightly in foil or plastic wrap and place it in an airtight container. It can last around 3 days in the fridge. Just remember: reheat it in an oven to avoid a soggy bun.

What Sides Would Complement the Whataburger Spicy Chicken Sandwich?

Pairing sides is an art. Here are three great picks for your meal:

1. French Fries

Crispy fries are a classic choice. Whether seasoned or sprinkled with cheese, they provide a comforting crunch against the spicy sandwich.

2. Baked Beans

Sweet and smoky baked beans are a down-home treat. Their sweetness counterbalances the heat beautifully, making for a well-rounded meal.

3. Chili

A hearty bowl of chili can also be an excellent side. Its warmth and spices complement the sandwich and fill you up just right.

What Alternatives Can You Use for the Ingredients?

Not every kitchen is equipped perfectly. If you can’t find what’s on the list, consider these substitutions:

1. Chicken Alternatives

If chicken isn’t available, turkey cutlets or even seasoned tofu can work instead. Each offers its own unique flavor and texture.

2. Flour Substitutes

For a gluten-free option, use almond flour or a gluten-free all-purpose blend instead of regular flour. This keeps the crispy aspect intact.

3. Mayonnaise Alternatives

If mayonnaise isn’t your cup of tea, Greek yogurt with a bit of vinegar can offer a healthier, tangy substitute for the spicy mayo.

4. Hot Sauce Variations

Not a fan of Sriracha? You can use any favorite hot sauce. Just remember, each brings its own level of heat and taste.
