Get the oven ready.
Preheat your oven to 375°F (190°C). Lightly grease a baking dish so nothing sticks and ruins your vibe. Season the chicken generously with salt, pepper, and garlic powder on both sides.
Make the creamy, cheesy layer.
In a bowl, mix the sour cream and shredded cheddar until smooth and spreadable. Slather this mixture over the chicken like you mean it. Thin spots are sad spots—coverage matters.
Create the golden topping.
Combine the crushed crackers with melted butter until everything looks evenly coated and slightly ridiculous. Sprinkle this mixture all over the chicken. This is where the crunch magic happens.
Bake it.
Bake uncovered for 30–35 minutes, until the chicken is cooked through and the topping is golden brown. If the crackers brown too fast, loosely cover with foil and keep going.
Rest, then serve.
Let the chicken rest for about 5 minutes. Sprinkle with dried parsley if you’re feeling fancy. Serve warm and enjoy the sound of people asking for seconds.
