My aunt served this at every graduation party for 40 years—and the sauce makes itself in the oven.
Some recipes become family traditions because they are complicated and impressive. Others become traditions because they are ridiculously easy, wonderfully comforting, and always disappear first. This 3-ingredient Chicken Elegante belongs firmly in the second category.
For four decades, my aunt served her version at graduation parties, family celebrations, church gatherings, and crowded Sunday dinners. She would line up casserole dishes on the serving table, and before long, the chicken would be gone and everyone would be asking who made it.
The secret is almost unbelievably simple: chicken breasts, condensed cream of mushroom soup, and sour cream. That’s it.
As the casserole bakes, the chicken releases its flavorful juices into the creamy soup mixture, creating a silky mushroom sauce right in the oven. There is no separate saucepan, no complicated roux, and no standing over the stove whisking sauce.
The result is tender, juicy chicken covered in a rich, creamy sauce that tastes much more luxurious than its humble ingredient list suggests. Spoon it over egg noodles, mashed potatoes, or rice, and you’ve got the kind of comforting dinner people remember.

– Great for entertaining: It looks elegant enough for a graduation party or Sunday dinner.
– Easy to customize: Chicken thighs, cream of chicken soup, or fresh mushrooms can all be used.

Ingredients for 3-Ingredient Chicken Elegante
2 1/2 to 3 pounds boneless, skinless chicken breasts
The chicken is the hearty foundation of this casserole. Use about 6 medium chicken breasts, depending on their size. If the breasts are particularly thick, slicing them horizontally helps them cook more evenly and prevents the outside from becoming overdone before the center reaches a safe temperature.
2 cans condensed cream of mushroom soup
Each can should be 10.5 ounces. This is the shortcut that creates the rich, savory foundation of the sauce. Because the soup is condensed, do not dilute it with water or milk. It will loosen naturally as it bakes with the sour cream and juices from the chicken.
1 cup sour cream
Sour cream adds creaminess, richness, and a subtle tang that balances the savory mushroom soup. Full-fat sour cream produces an especially luxurious sauce, but light sour cream can also be used.
Optional: Fresh parsley or black pepper
These aren’t part of the three-ingredient base, but a little fresh parsley or freshly cracked black pepper gives the finished casserole a simple, attractive finishing touch.

How to Make Oven-Baked 3-Ingredient Chicken Elegante
Step 1: Prepare the oven and casserole dish
Preheat your oven to 350°F (175°C).
Lightly grease a 9×13-inch casserole dish with cooking spray or a small amount of butter or oil. A glass or ceramic baking dish works especially well for this recipe.
Step 2: Prepare the chicken
Pat the chicken breasts dry with paper towels.
If the breasts are very thick, carefully slice them horizontally into thinner pieces. This helps them cook more evenly and makes serving easier.
Arrange the chicken in a single layer in the prepared casserole dish. Try not to overlap the pieces too much.
Step 3: Make the creamy mushroom mixture
Add the condensed cream of mushroom soup and sour cream to a medium bowl.
Stir until the mixture is mostly smooth and evenly combined.
Do not add water or milk. The mixture will look quite thick at this point, but that’s exactly what you want. The chicken’s juices and the heat of the oven will transform it into a smooth, creamy sauce.
Step 4: Cover the chicken with sauce
Pour the creamy mushroom mixture evenly over the chicken.
Use a spatula or the back of a spoon to spread the sauce so that most of the chicken is coated. A few edges peeking through are perfectly fine.
Step 5: Bake covered
Cover the casserole dish tightly with aluminum foil.
Place it in the preheated oven and bake for 35 minutes.
Keeping the casserole covered helps trap moisture, allowing the chicken to cook gently while the sauce becomes rich and creamy.
Step 6: Finish baking uncovered
Carefully remove the foil, watching for escaping steam.
Return the casserole to the oven and bake uncovered for another 15–20 minutes.
The sauce should be bubbling around the chicken with slightly golden edges.
Most importantly, check the thickest part of the chicken with an instant-read thermometer. It should reach 165°F (74°C) for safe consumption.
Step 7: Let the casserole rest
Remove the casserole from the oven and let it rest for 5–10 minutes.
This short resting period allows the sauce to thicken slightly and cling beautifully to the chicken.
Step 8: Serve
Spoon a generous amount of the creamy mushroom sauce over each piece of chicken.
Finish with a little chopped fresh parsley or freshly cracked black pepper if desired.
And don’t forget to spoon plenty of that sauce onto whatever side dish you’re serving—it is one of the best parts of the recipe.

Pro Tips for Perfect Chicken Elegante
Don’t dilute the condensed soup
This is one of the most important tips. Leave the soup condensed. Adding water or milk can make the sauce thinner than intended.
Use evenly sized chicken pieces
Very thick chicken breasts can take longer to cook. If necessary, slice them horizontally so the pieces are a similar thickness.
Don’t skip the resting time
Those extra 5–10 minutes after baking give the sauce time to settle and thicken slightly.
Check temperature rather than guessing
Chicken breasts can vary considerably in size. Always use an instant-read thermometer and make sure the thickest part reaches 165°F (74°C).
Want more mushroom flavor?
Scatter 1–2 cups of sliced fresh mushrooms over the chicken before adding the sauce. They’ll soften beautifully as the casserole bakes.
Prefer a milder sauce?
Replace the cream of mushroom soup with cream of chicken soup, or use one can of each.
Try chicken thighs
Boneless, skinless chicken thighs are an excellent alternative. They stay particularly juicy and pair wonderfully with the creamy sauce.
Make it extra pretty
A sprinkling of fresh parsley immediately before serving adds a little color without complicating the recipe.

What to Serve with Chicken Elegante
Because the sauce is so creamy and flavorful, this chicken pairs beautifully with simple sides.
Buttered Egg Noodles
Probably one of the best choices. The noodles catch every drop of the creamy mushroom sauce.
Mashed Potatoes
For the ultimate comfort-food dinner, spoon the chicken and sauce directly over fluffy mashed potatoes.
White Rice
Simple steamed rice provides a neutral base that lets the creamy sauce shine.
Green Beans
Steamed or roasted green beans add fresh color and a crisp contrast to the richness of the casserole.
Roasted Broccoli
The slight char from roasted broccoli pairs beautifully with the creamy sauce.
Fresh Green Salad
A crisp salad with a bright vinaigrette brings acidity and freshness to the meal.
Warm Bread or Dinner Rolls
Keep some crusty bread or warm dinner rolls nearby. You’ll want something to soak up every last bit of sauce.

Perfect for Family Gatherings and Potlucks
One reason this recipe has such staying power is its versatility.
It works just as well for a busy weeknight dinner as it does for a graduation party, church supper, family reunion, or Sunday gathering. The casserole can be prepared in one dish, baked until bubbling, and brought straight to the table.
For a crowd, slice the cooked chicken into thick strips and gently toss it with the sauce before serving. This creates an easy family-style chicken casserole that makes every serving generously coated in creamy mushroom sauce.
Just remember that perishable food should not remain at room temperature for more than 2 hours. Refrigerate leftovers promptly in a shallow container and use them within 3–4 days.
Frequently Asked Questions
Can I use chicken thighs instead of chicken breasts?
Yes. Boneless, skinless chicken thighs work very well and tend to stay especially juicy. Check the internal temperature before serving.
Can I use cream of chicken soup?
Absolutely. You can substitute cream of chicken soup for the mushroom soup, or use one can of each.
Do I need to add milk to the condensed soup?
No. For this recipe, do not dilute the condensed soup. The sauce loosens during baking as the chicken releases its juices.
Can I add mushrooms?
Yes. Add 1–2 cups of sliced fresh mushrooms before pouring the creamy mixture over the chicken.
How do I know when the chicken is done?
The thickest part of the chicken should reach 165°F (74°C) when checked with an instant-read thermometer.
