This oven baked 4-ingredient chicken Oscar has the kind of retro charm that explains why it kept showing up on holiday tables for decades. Built from just a handful of pantry and refrigerator staples, it turns plain chicken breasts into a creamy, comforting baked dish with a savory topping and a golden finish. It feels a little special without being fussy, which is exactly why recipes like this lasted in community cookbooks and family files.
Serve this chicken with fluffy rice, buttered egg noodles, or mashed potatoes to catch the extra sauce. For vegetables, steamed asparagus, green beans, or a simple salad with a tart vinaigrette balance the richness nicely. If you're serving it for a holiday meal, it fits right in beside rolls, glazed carrots, or a classic wild rice side.
Oven Baked 4-Ingredient Chicken Oscar
Servings: 6
Ingredients
6 boneless, skinless chicken breast halves
Directions
1. Preheat the oven to 350°F. Lightly grease a rectangular glass baking dish large enough to hold the chicken in a single layer.
2. Arrange the chicken breasts evenly in the prepared baking dish. If the pieces are very thick, pound them lightly so they cook more evenly.
3. In a medium bowl, stir together the condensed cream of mushroom soup and sour cream until smooth and well combined.
4. Spread the soup mixture evenly over the chicken breasts, covering the tops completely.
5. Sprinkle the bread crumbs over the top in an even layer. Bake uncovered for 45 to 55 minutes, or until the chicken is cooked through and the topping is golden brown.
6. Let the dish rest for 5 to 10 minutes before serving so the sauce settles slightly and the portions lift out more neatly.
Variations & Tips
Add asparagus: For a more classic chicken Oscar feel, tuck a few lightly cooked asparagus spears under or alongside the chicken before serving. That fresh green flavor cuts through the rich sauce beautifully.
Use fresh crumbs: If you prefer a softer, heartier topping, swap the dry bread crumbs for fresh bread crumbs tossed with a little melted butter. The crust will be less crisp but more tender and rustic.
Try a different soup: Cream of chicken or cream of celery soup both work well here and give the casserole a slightly different character. This is a good option if mushroom flavor is not your favorite.
Keep the chicken even: Chicken breasts vary a lot in thickness, so a quick pounding step helps the dish bake more uniformly. It also makes each serving easier to cut with a fork.
Prevent overbrowning: If the top is getting too dark before the chicken is fully cooked, loosely tent the dish with foil for the last 10 to 15 minutes of baking.
