Found this in my grandmother's recipe box labeled 'church potluck winner 1972.' Made it for my book club last week and they demanded the recipe.

This oven baked 4-ingredient chicken continental casserole is straight out of a vintage church cookbook era. I actually found a version of it in my grandmother’s recipe box, complete with a note that said, “church potluck winner 1972.” It’s the kind of creamy, comforting casserole that feels nostalgic but is still super practical for busy weeknights or casual get-togethers. I made it for my book club recently and they absolutely cleaned the pan, then insisted I text them the recipe that same night. It bakes up bubbly and golden with a crispy breadcrumb top, and the inside is all tender chicken and a velvety sauce—classic Midwestern comfort food with almost no effort.

Serve this casserole hot, straight from the oven, with something fresh and simple on the side to balance the richness—think a crisp green salad with a tangy vinaigrette or steamed green beans with a squeeze of lemon. Buttered egg noodles or mashed potatoes are great if you want to stretch it for a crowd, and a side of dinner rolls is perfect for scooping up the creamy sauce. For drinks, iced tea or a light white wine pairs nicely, and if you’re hosting something book club–style, a simple dessert like brownies or fruit crisp keeps the cozy, potluck vibe going.

Servings: 6

3 cups cooked chicken, cut into bite-size chunks (about 1 pound cooked)

Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch glass or Pyrex baking dish so the casserole releases easily and the edges don’t stick.

In a large mixing bowl, stir together the condensed cream of chicken soup and sour cream until the mixture is completely smooth and blended. This is your creamy “continental” style sauce base.

Add the cooked chicken chunks to the bowl and gently fold them into the sauce until every piece is well coated. If your chicken is straight from the fridge, let it sit in the sauce for a few minutes while you prep the dish so it warms slightly before baking.

Sprinkle 1/2 cup of the seasoned dry breadcrumbs evenly over the bottom of the prepared baking dish to create a light crumb base. This helps soak up some of the sauce and gives the bottom a little texture instead of getting soggy.

Spoon the chicken and sauce mixture into the baking dish on top of the crumb base, spreading it out into an even layer all the way to the corners. Gently smooth the top with the back of your spoon so the casserole bakes evenly.

Sprinkle the remaining 1 cup of seasoned dry breadcrumbs evenly over the top of the casserole. Try to cover the surface from edge to edge so you get a golden, crispy topping in every scoop.

Place the baking dish on the center rack of the preheated oven and bake for 30 to 35 minutes, or until the casserole is bubbly around the edges and the breadcrumb topping is a deep golden brown. If your breadcrumbs are browning too quickly, you can loosely tent the dish with foil for the last 5 to 10 minutes.

Remove the casserole from the oven and let it rest on a heatproof surface for about 8 to 10 minutes. This short rest helps the creamy interior thicken slightly so it scoops more neatly while still staying soft and saucy.

Use a large wooden spoon to scoop generous portions, making sure to dig all the way down so each serving gets some of the creamy interior, tender chicken, and crispy breadcrumb topping. Serve warm and enjoy that cozy, old-school potluck feel.

If you want to stretch this casserole a bit further, you can fold in up to 1 cup of frozen peas or mixed vegetables (thawed and well-drained) along with the chicken, though that will technically add more ingredients beyond the base four. For extra richness, you can swap half of the sour cream for plain Greek yogurt for a little tang, or use one can of cream of mushroom soup and one can of cream of chicken for a more classic 1970s flavor mix. If you like a slightly cheesier vibe, sprinkle 1/2 cup of shredded Swiss or mild cheddar under the breadcrumb topping before baking. To make ahead, assemble the casserole up to the breadcrumb topping, cover tightly, and refrigerate up to 24 hours; when baking from cold, add 5 to 10 extra minutes and check that it’s bubbling hot in the center. For food safety, always start with fully cooked chicken—rotisserie, poached, or leftover roast—and never leave the casserole out at room temperature for more than 2 hours. If you’re cooling leftovers, transfer them to shallow containers so they chill faster, and refrigerate within 2 hours of baking. Reheat leftovers in a 350°F (175°C) oven until steaming hot in the center (165°F if you’re checking with a thermometer) so the chicken stays safe to eat and the topping crisps back up a bit.
