Step 1: Bring a large pot of salted water to a boil. Cook the penne pasta according to package instructions until al dente. Reserve 1/2 cup of pasta water before draining.
Step 2: While the pasta cooks, heat the olive oil in a large skillet over medium-high heat. Season the chicken strips with salt and pepper, then add them to the skillet.
Step 3: Cook the chicken for 5-7 minutes until golden brown and cooked through. Remove the chicken from the skillet and set aside on a plate.
Step 4: In the same skillet, add the diced onion. Sauté for 3-4 minutes until translucent. Add the minced garlic and cook for another minute until fragrant.
Step 5: Stir in the minced chipotle peppers and the adobo sauce. Pour in the heavy cream and bring to a gentle simmer.
Step 6: Reduce heat to low and stir in the Parmesan cheese until melted and the sauce has thickened slightly.
Step 7: Add the cooked pasta and chicken back into the skillet. Toss everything together until the pasta is well coated. If the sauce is too thick, add a splash of the reserved pasta water.
Step 8: Garnish with fresh cilantro and serve immediately with lime wedges on the side.
