Heat olive oil in a large skillet over medium-high heat until it shimmers slightly. Slice chicken breasts horizontally to create thinner pieces that cook faster—I learned this speeds everything up by almost 10 minutes.

Season chicken with cumin and smoked paprika on both sides, then cook for 5-6 minutes per side until internal temperature reaches 165°F. Don't skip checking temperature because undercooked chicken ruins the entire dish, but overdone chicken becomes rubbery no matter what sauce surrounds it.

Remove chicken to a cutting board and let it rest for 3 minutes while you dice the onion. This resting period matters because it redistributes juices throughout the meat, making every bite tender rather than just the center.

In the same skillet, sauté diced onion and minced garlic for 2-3 minutes until the garlic becomes fragrant and onions turn translucent. I always smell for that moment when raw garlic aroma shifts to toasted garlic aroma—that's your signal to proceed immediately or it'll taste bitter.

Meanwhile, cook penne according to package directions until just past al dente—about 1-2 minutes longer than the package suggests. This matters for this stunning chicken enchilada pasta summer recipe because the pasta continues cooking in the oven, and you want it tender without turning to mush.

Chop the rested chicken into bite-sized pieces, then add them back to the skillet along with corn kernels and black beans. Stir everything together and let it warm for 2 minutes, which is enough time to heat the beans through without cooking away their texture.

Drain penne, then combine it with the chicken mixture in the skillet. Pour enchilada sauce over everything and stir until every piece of pasta wears a light coating—don't oversaturate because the cheese layer will add richness.

Transfer everything to a baking dish, top with cheddar cheese, and bake at 375°F for 12-15 minutes until cheese melts and the edges bubble slightly. I watch for that moment when steam rises from the edges but the cheese still looks creamy rather than golden-brown, because overcooked cheese separates into an oily mess.

Remove from oven and let it rest for 5 minutes before plating. Squeeze fresh lime juice over each serving and scatter cilantro on top—this final step transforms the entire dish from "good" into something that actually surprises people.
