Cheesy Chicken and Chile Casserole

A comfort-food casserole combining seasoned chicken, roasted vegetables, and a creamy queso sauce studded with diced tomatoes and green chiles. The chicken stays moist under a blanket of melted Mexican-blend cheese, making this a weeknight dinner that feeds 4-6. Light sour cream and reduced-fat cream cheese keep it reasonable without sacrificing richness. Serve with rice, tortillas, or a simple salad for a complete meal.

Instructions

  1. 1

    Preheat oven to 375F.

  2. 2

    Spray an 8-by-8-inch baking pan with nonstick spray.

  3. 3

    Add chicken to the pan and season with taco seasoning and garlic powder. Top with onion and pepper.

  4. 4

    In a large microwave-safe bowl, combine half the cheese with sour cream, cream cheese, remaining taco seasoning, and remaining garlic powder. Microwave 1 minute until cheese melts. Stir until smooth.

  5. 5

    Add diced tomatoes with chiles to the bowl and mix well.

    Garnish with fresh cilantro if desired.

Tips

Tip 1

Microwave the cheese mixture in short bursts, stirring between intervals, to avoid overheating and curdling the cream cheese.

Tip 2

Let the casserole rest 5 minutes after baking before serving so the filling sets slightly and portions cleanly.

Tip 3

Prep vegetables while the oven preheats to streamline cooking time.

Good to Know

Storage

Cover and refrigerate up to 4 days. Reheat covered at 350F for 15-20 minutes until warm through.

Make Ahead

Serve With

Common Mistakes

Watch

Do not skip draining the tomatoes to avoid a watery casserole.

Watch

Do not overbake after adding the final cheese layer to prevent drying out the chicken.

Watch

Do not stir the cheese sauce after baking or it will become stringy; smooth it in the bowl before transferring.

FAQ

Can I use bone-in, skin-on chicken?

Yes, but increase covered baking time to 25-30 minutes. Check that the thickest piece reaches 165F internally before proceeding.

What if I don't have reduced-fat cheese?

Full-fat cream cheese and sour cream work fine and yield a richer dish. Use the same quantities; the casserole may be slightly heavier.

Can I freeze this casserole?

Yes, freeze unbaked (through step 6) up to 3 months. Thaw in the fridge overnight and bake as directed, adding 5 minutes if cold.
