This oven baked 4-ingredient chicken amandine casserole is the kind of practical mid-century supper that earned a permanent place in family recipe boxes: simple chicken breasts, a creamy pantry-style sauce, and a shower of almonds that turn fragrant and toasty in the oven. It has the familiar comfort of a church-supper casserole, but the almonds give it just enough elegance to make it feel company-worthy, which helps explain why a dish like this would have shown up at reunions again and again in the early 1970s.
Serve this casserole with plain rice, buttered egg noodles, or mashed potatoes to catch the creamy sauce. A green vegetable such as steamed broccoli, green beans, or asparagus balances the richness nicely, and a crisp salad with a tart vinaigrette is especially welcome alongside the buttery almonds and baked chicken.
Oven Baked 4-Ingredient Chicken Amandine Casserole
Servings: 4 to 6
Ingredients
4 boneless, skinless chicken breasts
1 (10.5-ounce) can condensed cream of chicken soup
1 cup sour cream
1 cup slivered almonds
Directions
1. Preheat the oven to 350°F and lightly grease a rectangular baking dish. Pat the chicken breasts dry and arrange them in a single layer in the dish.
2. In a medium bowl, stir together the condensed cream of chicken soup and sour cream until smooth. Spread the mixture evenly over the chicken breasts.
3. Sprinkle the slivered almonds evenly over the top, covering the sauce in a generous layer.
4. Bake uncovered for 40 to 50 minutes, or until the chicken is cooked through and the casserole is bubbling around the edges. If the almonds brown too quickly, loosely tent the dish with foil near the end of baking.
5. Let the casserole rest for 5 to 10 minutes before serving so the sauce thickens slightly and the chicken stays juicy.
Variations & Tips
Add a little seasoning: If you want to stay close to the original while building in more flavor, add a pinch of black pepper, a little garlic powder, or a few shakes of paprika to the sauce. Even though the base recipe is only four ingredients, a small amount of seasoning helps modern palates without changing its character.
Use chicken cutlets for faster baking: If your chicken breasts are especially thick, slice them horizontally into thinner cutlets so they cook more evenly and stay tender. This also shortens the baking time, so begin checking for doneness around 30 minutes.
Toast the almonds first: For deeper nutty flavor, toast the slivered almonds in a dry skillet for a few minutes before adding them to the casserole. Let them cool slightly before scattering over the sauce so they keep their texture and color more reliably in the oven.
Make it reunion-ready: To stretch the casserole for a larger table, cut the chicken into large chunks before arranging it in the dish, then serve the finished casserole over rice or noodles. It will feel more like a classic potluck bake and gives every serving a good spoonful of sauce and almonds.
