Can I use chicken thighs instead of breast?
Yes. Thighs will be juicier and more forgiving; reduce cooking time slightly as they're smaller or cube larger pieces.
How do I make this less spicy?
Remove jalapeño seeds before chopping, use half a jalapeño, or omit entirely and add a pinch of smoked paprika for flavor without heat.
Can I prepare this ahead of time?
Sear the chicken and chop vegetables up to 1 day ahead. Assemble and cook fresh to keep the sauce creamy; reheated sauce may separate slightly.
What pasta shape works best?
Penne, rigatoni, or fettuccine work well. Avoid very thin shapes that may break in the creamy sauce.
How do I know when the chicken is done?
Sear until golden on all sides (2–3 minutes per side), then finish cooking in the sauce until internal temperature reaches 165°F or the thickest piece is no longer pink.
