Tender chicken folded into a creamy sour cream sauce and baked under a buttery Ritz cracker topping. It's a comfort food classic that comes together with just 10 minutes of prep.
Preheat oven to 350°F. Grease a 9x13-inch baking dish.
In a large bowl, stir together the cream of chicken soup, sour cream, poppy seeds, Parmesan cheese, black pepper, parsley, and garlic powder until smooth.
Add the chicken and stir until completely coated in the sauce. Transfer to the prepared baking dish and spread into an even layer.
In a medium bowl, pour the melted butter over the crushed Ritz crackers and toss with a fork until evenly coated. Sprinkle over the chicken filling.
Bake uncovered for 35 to 40 minutes, until hot all the way through and bubbling around the edges.
Let rest 5 minutes before serving.
Notes
Chicken: Any cooked chicken works. Boil in water or broth for 15 to 20 minutes, bake at 400°F for about 20 minutes to an internal temperature of 165°F, or use a store-bought rotisserie chicken.
Cracker swaps: Saltines or club crackers are the closest substitute. Crushed cornflakes, panko, or potato chips also work.
Cheese options: Freshly grated Parmesan melts most smoothly. Swap in pepper jack for a little heat or cheddar for a milder, meltier result.
Adding vegetables: Stir in about 1 cup of thawed peas or small broccoli florets. Pat them dry first so the sauce doesn't thin out.
Serving: Delicious over rice or egg noodles, or on its own with a green vegetable alongside.
Bake uncovered. Covering traps steam and softens the cracker topping.
Make ahead: Assemble without the topping and refrigerate up to 24 hours. Add the buttered crackers just before baking.
Freezing: Freeze unbaked and untopped for up to 3 months. Thaw overnight in the fridge, add the topping, and bake with 5 to 10 extra minutes.
Storage: Refrigerate leftovers in an airtight container for 3 to 4 days.
