Chicken Delmonico is one of those practical mid-century casseroles that earned its place in church cookbooks, neighborhood card parties, and garden club recipe swaps because it transforms a few pantry staples into something rich and comforting. This oven-baked 4-ingredient version leans into that tradition, pairing tender chicken with a creamy sauce and a savory crumb topping that browns beautifully in the oven, giving you a dish that tastes far more elaborate than its short ingredient list suggests.
Serve this with simple sides that can soak up the extra sauce, such as buttered egg noodles, steamed rice, or mashed potatoes. A crisp green salad, green beans, or roasted broccoli adds welcome contrast to the richness, and if you are bringing it to a potluck table, warm dinner rolls make it feel especially complete.
Oven Baked 4-Ingredient Chicken Delmonico
Servings: 6
Ingredients
2 1/2 to 3 pounds boneless, skinless chicken breasts or chicken tenders
Directions
1. Heat the oven to 350°F and lightly grease a 9-by-13-inch baking dish or a similar shallow casserole.
2. If the chicken breasts are large, cut them into smaller cutlets or thick strips so they cook evenly, then arrange the chicken in a single layer in the prepared baking dish.
3. In a medium bowl, stir together the condensed cream of chicken soup and sour cream until smooth, then spread the mixture evenly over the chicken.
4. Sprinkle the seasoned bread crumbs evenly over the top, covering the sauce from edge to edge for a full golden crust.
5. Bake uncovered for 40 to 50 minutes, or until the chicken is cooked through and the topping is crisp and deep golden brown. If needed, let it rest for 5 minutes before serving so the sauce settles slightly.
Variations & Tips
Use chicken thighs: Boneless, skinless chicken thighs work very well here and stay especially juicy. They may need a few extra minutes in the oven, so check that they are fully cooked before serving.
Adjust the topping: If you like a crunchier finish, toss the bread crumbs with a small drizzle of melted butter before sprinkling them over the casserole. That little step helps the top brown more evenly and gives it a more classic baked-casserole texture.
Keep the sauce balanced: Because condensed soup and seasoned bread crumbs already contain salt, taste add-ins carefully if you decide to improvise. This is one of those older recipes where restraint pays off and the simple combination is the reason it works.
Make it ahead: Assemble the chicken and sauce in the baking dish up to a day in advance, then cover and refrigerate. Add the bread crumbs just before baking so the topping stays dry and bakes up crisp.
