There are some casseroles that feel plain on paper and then surprise everybody at the table, and Chicken Kensington is one of those. With just a handful of pantry-friendly ingredients, this oven-baked dish turns simple chicken breasts into something creamy, savory, and worthy of passing around at a summer supper or Sunday dinner. It has that practical Midwestern spirit too—easy enough for a busy day, but comforting in the old-fashioned way that makes folks go back for a second spoonful.
This dish is lovely served with buttered egg noodles, fluffy white rice, or mashed potatoes to catch every bit of the creamy golden sauce. For vegetables, green beans, buttered peas, or a crisp cucumber salad make a fine contrast, and if you are feeding a crowd, a basket of warm rolls on the side never goes to waste.
Oven Baked 4-Ingredient Chicken Kensington
Servings: 6
Ingredients
2 pounds boneless, skinless chicken breasts, cut into serving-size pieces
1 can condensed cream of chicken soup
1 cup sour cream
1 envelope dry onion soup mix
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch baking dish.
2. Arrange the chicken breast pieces in an even layer in the prepared baking dish.
3. In a medium bowl, stir together the condensed cream of chicken soup, sour cream, and dry onion soup mix until smooth and well blended.
4. Spoon the sauce evenly over the chicken, spreading it to coat all the pieces well.
5. Bake uncovered for 45 to 55 minutes, or until the chicken is fully cooked and the top is lightly browned around the edges.
6. Let the casserole rest for 5 to 10 minutes before serving so the sauce can settle and thicken slightly.
Variations & Tips
For extra color: Scatter a little chopped fresh parsley over the top just before serving. It is not necessary, but it does brighten the rich sauce and makes the casserole look especially nice on the table.
For a richer bake: If you like a little more sauce for spooning over rice or potatoes, you can add an extra half cup of sour cream. The casserole will stay creamy and satisfying without changing its old-fashioned character.
For easier serving: Cut the chicken into evenly sized pieces before baking so everything cooks at the same pace. Thin pieces may be done sooner, so start checking early if your chicken breasts are small.
For make-ahead convenience: Assemble the dish a few hours ahead, cover, and refrigerate. When you are ready to bake, let it sit at room temperature for about 20 minutes while the oven heats, then bake as directed.
For a heartier supper: Serve this chicken over hot rice, noodles, or mashed potatoes so none of that creamy onion sauce goes to waste. That is the sort of thrifty, good-sense cooking that has kept casseroles popular for generations.
