Frequently Asked Questions
- → How spicy is this meal?
- It’s mild to medium, with warmth from the jalapeño. Remove the seeds for less spice or use a milder pepper like poblano. Want it hotter? Toss in extra jalapeños or cayenne.
- → Can chicken thighs be substituted?
- Absolutely! Boneless, skinless thighs work perfectly and may even stay juicier. Time stays about the same—just make sure they reach 165°F/74°C.
- → What sides pair well with this?
- Cilantro lime rice, black beans, or a fresh salad work awesome. For low-carb, try cauliflower rice or roasted veggies. Stuffing it into tacos? Even better!
- → Is this dish good for prepping ahead?
- Definitely! You can chop the veggies and season the chicken ahead of time. Store separately, then bake fresh. Or fully cook it, then reheat at 350°F later.
- → What cheese could replace mozzarella?
- Options like Monterey Jack, pepper jack, or Mexican cheese blends are great swaps. For authenticity, queso fresco or queso Oaxaca work too, but they don’t melt as much.
