1-Step 1: Prepare and Season the Chicken. Start by preparing your chicken breast. Pat the meat dry with paper towels to help the seasoning adhere better. In a small bowl, combine the salt, white pepper, paprika, garlic powder, dried oregano, and dried rosemary. Mix these spices well to distribute the flavors evenly. Rub the spice mixture evenly over both sides of the chicken breast, making sure every inch is coated. This seasoning blend creates a flavorful foundation that pairs beautifully with the creamy Alfredo sauce.

2-Step 2: Sear the Chicken. Heat the butter and oil in a large pan over medium-high heat. The combination of butter and oil gives you the rich flavor of butter with the higher smoke point of oil, preventing burning. Once the butter melts and bubbles slightly, add the seasoned chicken breast to the pan. Sear the chicken for approximately 3-4 minutes on each side until lightly golden but not fully cooked through. You’re looking for a nice brown exterior while keeping the inside slightly underdone since it will finish cooking in the sauce. Remove the chicken from the pan and set it aside on a plate.

3-Step 3: Create the Alfredo Sauce. In the same pan you used for the chicken, lower the heat to medium and pour in the heavy cream. The remaining butter and flavorful bits from searing the chicken will infuse into the sauce, adding extra depth of flavor. Let the cream simmer gently for 2-3 minutes, stirring occasionally to prevent scorching. Once the cream has reduced slightly and begun to thicken, add the Parmesan, mozzarella, and Emmentaler cheese. Stir continuously with a whisk or wooden spoon until all the cheese has melted and the sauce is smooth and creamy. This should take about 2 minutes.

4-Step 4: Reserve Sauce for Dipping. Before adding the chicken back to the pan, transfer about half of the Alfredo sauce to a separate bowl. Set this aside for serving as a dipping sauce. This step is crucial because it ensures you’ll have plenty of smooth, flavorful sauce for dipping the finished tacos.

5-Step 5: Finish Cooking the Chicken in the Sauce. Return the seared chicken to the pan with the remaining sauce. Simmer the chicken in the Alfredo sauce for 1-2 minutes, spooning the sauce over the meat as it cooks. The chicken should reach an internal temperature of 165°F (74°C) and be cooked through completely. Remove the pan from the heat. If you prefer, you can slice or shred the chicken at this point, or leave it whole depending on your preference for filling the tacos.

6-Step 6: Assemble the Tacos. Now comes the fun part: assembling your tacos. Lay out your tortillas on a clean work surface. On each tortilla, start by layering some shredded Emmentaler cheese directly on the tortilla. This cheese acts as a barrier between the sauce and the tortilla, helping to prevent sogginess. Add a generous portion of the Alfredo chicken mixture on top of the cheese, then sprinkle more shredded Emmentaler on top. The cheese on both sides creates that irresistible cheese pull when you bite into the finished taco. Fold each tortilla in half, pressing gently to seal. The cheese on the edges will help seal the taco during frying, preventing the filling from leaking out.

7-Step 7: Fry to Golden Perfection. Heat about 1/4 inch of oil in a clean pan over medium heat. Working in batches of 2-3 tacos at a time, place the folded tacos in the hot oil. Fry for 2-3 minutes on each side until the tortillas are golden brown and crispy, and the cheese inside has completely melted. Remove the tacos from the oil and place them on a paper towel-lined plate to drain excess oil. Let them rest for about a minute before serving. This resting period allows the filling to thicken slightly, making the tacos easier to handle and preventing soggy bottoms.

8-Step 8: Serve and Enjoy. Transfer your crispy tacos to a serving platter. Sprinkle with extra Parmesan cheese for garnish and serve immediately while hot and crispy. Don’t forget to include the reserved Alfredo sauce on the side for dipping. Each bite delivers a satisfying crunch followed by creamy, cheesy, chicken-filled goodness.
