Start by chopping the bell pepper, onion, and cilantro. Mince the garlic and set aside. I like to prep everything first to make cooking smoother.
Boil penne pasta in salted water until al dente. Drain and toss with a tiny drizzle of olive oil to prevent sticking. Cooking pasta properly ensures the sauce clings nicely.
Heat olive oil in a skillet, season chicken with salt, pepper, cumin, and paprika. Cook until golden brown and cooked through, then slice into bite-sized pieces. I love the aroma that fills the kitchen at this step.
In the same skillet, sauté onions, bell peppers, and garlic until softened. This builds the flavor base for your creamy sauce.
Add chicken broth, heavy cream, chili powder, and cayenne. Stir until combined, then fold in shredded cheddar cheese. Let it melt and thicken slightly. The sauce should coat the back of a spoon.
Add the cooked pasta and chicken back to the skillet. Toss to coat evenly. Finish with fresh lime juice and chopped cilantro for a burst of freshness.
