Step 1: Prepare the Chicken

1. Place the chicken breasts between two pieces of plastic wrap and pound to an even thickness (about ½ inch) for even cooking.
2. In a small bowl, mix the chili powder, smoked paprika, garlic powder, onion powder, salt, and black pepper. Rub this spice mixture evenly over both sides of the chicken breasts.

Step 2: Cook the Chicken

1. Heat olive oil in a large skillet over medium-high heat.
2. Add the chicken breasts and cook for 4-5 minutes per side, or until golden brown and cooked through (internal temperature of 165°F or 75°C).
3. Remove the chicken from the skillet and let it rest on a cutting board. Slice into thin strips or cubes once cooled slightly.

Step 3: Cook the Pasta

1. While the chicken is cooking, bring a large pot of salted water to a boil.
2. Cook the pasta according to the package instructions until al dente. Reserve 1 cup of pasta water before draining. Set the pasta aside.

Step 4: Make the Chipotle Cream Sauce

1. In the same skillet used for the chicken, reduce the heat to medium and add the butter. Allow it to melt.
2. Add the minced garlic and sauté for 1 minute until fragrant.
3. Stir in the chopped chipotle peppers and adobo sauce. Cook for 1-2 minutes, allowing the flavors to meld.
4. Pour in the heavy cream and chicken broth, stirring to combine.
5. Add the Parmesan cheese, smoked paprika, and cumin. Stir until the cheese is melted and the sauce is smooth.
6. Simmer the sauce for 3-5 minutes, stirring occasionally, until it thickens slightly. Taste and adjust the seasoning with salt and black pepper.

Step 5: Combine the Pasta and Chicken

1. Add the cooked pasta to the skillet, tossing it in the chipotle cream sauce until well coated. If the sauce is too thick, add reserved pasta water a little at a time until the desired consistency is reached.
2. Gently fold in the sliced chicken. If using optional add-ins like cherry tomatoes or peas, stir them in at this stage.

Step 6: Serve and Garnish

1. Transfer the pasta to serving bowls or a large platter.
2. Garnish with fresh cilantro or parsley and serve with lime wedges for a zesty touch.
3. Pair with a side salad or garlic bread for a complete meal.
