Every church cookbook from 1965 to 1985 had some version of this. Only 4 ingredients and it feeds a crowd.

This oven baked 4-ingredient cathedral chicken is exactly the kind of thing you’d find in every church cookbook from the late 60s through the 80s: simple pantry ingredients, big 9x13 pan, creamy chicken filling, and a buttery, crispy topping. It’s the kind of casserole that shows up at potlucks, funeral lunches, and weeknight tables when you need to feed a crowd without babysitting a skillet. Everything bakes together into cozy layers—tender chicken, a creamy sauce, and a golden crunchy top that looks right at home in a glass baking dish on a church basement buffet line.

Serve this cathedral chicken hot, scooped out in big squares with a sturdy spatula. It’s perfect over white rice, buttered egg noodles, or mashed potatoes to soak up the creamy sauce. Add a simple green salad or steamed green beans for something fresh and crunchy on the side, and maybe some dinner rolls if you’re really leaning into that potluck vibe. Leftovers reheat well for lunches, especially with a side of roasted vegetables or a quick bagged salad.

Servings: 8-10

2 pounds boneless, skinless chicken breasts, cut into bite-size pieces

Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch glass baking dish so the creamy sauce and crispy topping release easily when serving.

Spread the bite-size pieces of raw chicken evenly in the bottom of the prepared baking dish, making a single, fairly even layer so they cook at the same rate.

In a medium bowl, stir together the condensed cream of chicken soup and the sour cream until completely smooth and blended. It will be thick—that’s what you want for a creamy casserole layer.

Pour the soup and sour cream mixture over the chicken and gently spread it with a spatula to cover all the pieces. Try to avoid leaving any chicken exposed so it stays tender and juicy under the sauce.

Place the buttery round crackers in a large zip-top bag and crush them with your hands or a rolling pin until you have coarse, sandy crumbs with a few small chunks for texture.

Sprinkle the crushed cracker crumbs evenly over the top of the creamy chicken layer, covering the surface from edge to edge. This will bake into a crispy, golden topping.

Transfer the baking dish to the preheated oven and bake, uncovered, for 35–45 minutes, or until the cracker topping is deep golden brown and the chicken is cooked through (internal temperature reaches 165°F/74°C in the thickest pieces). The edges should be bubbly and the top crisp.

Let the casserole rest for about 5–10 minutes after you take it out of the oven. This helps the creamy layer thicken slightly so you can lift out neat squares with a spatula, showing the layers of chicken, sauce, and crunchy topping.

Use a sturdy spatula to scoop or lift out portions, making sure to dig down through all the layers so every serving gets creamy chicken and plenty of crispy topping.

To keep the spirit of those old church cookbooks, the base recipe stays at four ingredients, but you can still tweak it a bit once you’re comfortable. For extra flavor without adding more ingredients, use a mix of light and dark meat (boneless thighs plus breasts) for a richer, more forgiving texture that’s less likely to dry out. You can also swap one can of cream of chicken soup for cream of mushroom or cream of celery if that’s what you have in the pantry. If you want visible herbs like in those nostalgic casseroles, choose a condensed soup that’s labeled with herbs (such as cream of chicken with herbs), or garnish after baking with a sprinkle of dried parsley or a little chopped fresh parsley—just know that technically adds an extra ingredient. For a slightly lighter version, use light sour cream and reduced-fat condensed soup; the texture will still be creamy, though a bit less rich. If you’re cooking ahead, assemble the casserole up through adding the creamy layer, cover tightly, and refrigerate up to 24 hours; wait to add the cracker crumbs until just before baking so they stay crisp. Food safety tips: Always start with fully thawed chicken—never bake from frozen in this recipe, or the timing will be off and the center may not reach a safe temperature. Use a food thermometer to confirm the chicken hits 165°F/74°C in the middle of the pan. If you prep this in advance, keep it refrigerated until baking and don’t leave the finished casserole at room temperature for more than 2 hours (or 1 hour if it’s very warm in your kitchen). Store leftovers in an airtight container in the fridge and eat within 3–4 days, reheating until hot all the way through before serving.
