This is the kind of dish that showed up on every church basement buffet table from the mid-70s clear into the 2000s, usually in a well-worn glass baking dish with somebody’s name scratched on the bottom. My mother-in-law called it her “potluck chicken,” and I don’t think she ever came home with leftovers.
It’s only three ingredients, nothing fancy at all, but the way the sauce bakes down around the chicken makes a glossy, savory glaze with sticky, caramelized edges that people remember. It’s the recipe folks still ask me for at funerals, baby showers, and every small-town supper in between.

This chicken is right at home next to a bowl of fluffy mashed potatoes or buttered egg noodles, where all that extra sauce can soak in. At a potluck, I like to set it out with a pan of baked rice, a big green salad, and some buttered corn or green beans.
Dinner rolls or slices of soft white bread are nice for mopping up the juices. It’s also good the next day, shredded over rice or tucked into a soft roll with a spoonful of the leftover sauce.
Oven-Baked 3-Ingredient Church Supper Chicken
Servings: 6
Ingredients
3 to 3 1/2 pounds bone-in, skin-on chicken pieces (thighs and drumsticks work best)

Directions
Preheat your oven to 350°F (175°C). Set out a 9×13-inch glass baking dish. There is no need to grease the dish; the chicken will release some fat as it cooks.
Pat the chicken pieces dry with paper towels. This helps the sauce cling better and keeps the finished dish from getting too watery. Arrange the chicken in a single layer in the glass baking dish, skin side up, with the pieces snug but not piled on top of each other.

In a medium bowl, stir together the barbecue sauce and the lemon-lime soda until smooth and well combined. It will look thin at first; that is exactly what you want, as it will thicken and turn glossy in the oven.
Pour the sauce mixture evenly over the chicken pieces, lifting them slightly with a spoon or tongs so some sauce can get underneath. Spoon a little extra sauce over the tops so all the chicken is well coated and nestled in the liquid.
