Ingredients for Oven-Baked 3-Ingredient Chicken Delmonico
This recipe keeps things wonderfully simple. Each ingredient has an important job in creating the tender chicken and creamy, cheesy finish.
1. 2 Pounds Boneless, Skinless Chicken Breasts or Chicken Tenders
Chicken is the hearty foundation of this easy oven-baked chicken casserole. Boneless, skinless chicken breasts provide generous portions and a mild flavor that pairs beautifully with the creamy sauce. Chicken tenders are another excellent choice because they’re smaller and cook relatively quickly.
For the most even results, choose chicken pieces of similar thickness. If your chicken breasts are especially large, consider cutting them into evenly sized portions so they cook more consistently.
2. 1 Can Condensed Cream of Chicken Soup, Undiluted
Condensed cream of chicken soup is the secret to creating a creamy sauce without preparing a separate roux or cheese sauce. Its concentrated flavor gives the dish a savory, comforting base, while its creamy texture coats the chicken as it bakes.
Do not add water or milk to the condensed soup for this recipe. Keeping it undiluted helps the finished sauce remain rich and spoonable rather than overly thin.
3. 2 Cups Shredded Swiss Cheese
Swiss cheese provides the signature cheesy topping. It melts beautifully over the creamy soup, adding a mild, nutty flavor that complements the chicken without overpowering it.
For the best melt, shred a block of Swiss cheese yourself if possible. Pre-shredded cheese is convenient, but freshly shredded cheese often melts more smoothly because it contains less added anti-caking coating.
How to Make Oven-Baked 3-Ingredient Chicken Delmonico
This easy baked chicken dinner requires only a few simple steps. Prepare the casserole, place it in the oven, and let the ingredients come together into a comforting meal.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a rectangular baking dish or casserole dish with butter or cooking spray to help prevent sticking and make serving easier.
Choose a dish large enough to hold the chicken in a single layer without crowding the pieces too tightly.
Step 2: Arrange the Chicken
Place the boneless, skinless chicken breasts or tenders in the prepared baking dish.
Arrange the pieces in a single layer, leaving a little space between them when possible. This helps the chicken cook evenly and allows the creamy sauce to spread around each piece.
If you’re using thick chicken breasts, try to choose pieces of similar thickness so they finish cooking at approximately the same time.
Step 3: Add the Cream of Chicken Soup
Open the can of condensed cream of chicken soup and spoon it evenly over the chicken.
Use the back of a spoon or a spatula to spread the soup across the surface, covering the chicken as thoroughly as possible. The soup will help create the creamy sauce that makes this simple casserole so satisfying.
Remember to leave the soup undiluted.
Step 4: Cover with Swiss Cheese
Sprinkle the 2 cups of shredded Swiss cheese evenly over the soup-covered chicken.
Spread the cheese from edge to edge so every portion gets a generous layer. As the casserole bakes, the cheese will melt into the sauce and develop a deliciously golden surface in places.
Step 5: Bake Until Hot and Cooked Through
Place the uncovered casserole in the preheated oven and bake for approximately 35–45 minutes.
The exact cooking time depends on the thickness of the chicken and the size of your baking dish. Begin checking the chicken toward the earlier end of the cooking range.
For food safety, use an instant-read thermometer to check the thickest part of the chicken. It should reach 165°F (74°C). The cheese should be melted, and the sauce should be hot and bubbling around the edges.
If the chicken reaches a safe temperature before the cheese develops the color you want, you can briefly broil the top, watching carefully to prevent burning.
Step 6: Rest and Serve
Remove the casserole from the oven and allow it to rest for about 5 minutes before serving.
This short resting period lets the sauce settle slightly and makes it easier to spoon over the chicken. Serve each portion with plenty of creamy sauce and melted cheese.
For a complete old-fashioned Sunday dinner, pair it with mashed potatoes, egg noodles, or white rice, plus a simple vegetable on the side.
Helpful Tips for the Best Chicken Delmonico
A few small details can make this three-ingredient casserole even better.
Choose evenly sized chicken pieces. Similar thickness helps the chicken cook at a consistent rate and reduces the chance of dry edges or undercooked centers.
Avoid overbaking. Chicken breasts can become dry when left in the oven too long. Check the internal temperature rather than relying on cooking time alone.
Keep the soup undiluted. The condensed soup is intended to form a thick, creamy sauce as the chicken releases moisture during baking.
Shred your own cheese. Freshly shredded Swiss cheese generally melts smoothly and creates a lovely cheesy topping.
Let the casserole rest. Five minutes of resting helps the sauce settle before you spoon it onto plates.
Season to taste if desired. The three-ingredient version relies on the flavors of the soup and cheese. If you prefer a little extra flavor, add black pepper, garlic powder, or a pinch of dried thyme. These are optional additions rather than part of the original three-ingredient recipe.
Use a thermometer. The chicken must reach an internal temperature of 165°F (74°C) for safe serving. Avoid judging doneness by the cheese color alone.
Easy Variations to Try
One of the best things about this simple chicken casserole is how easily you can adapt it to your family’s preferences.
Use Boneless Chicken Thighs
Boneless, skinless chicken thighs are a flavorful alternative to chicken breasts. They tend to stay juicy and have a slightly richer flavor. Arrange them in a single layer and cook until they reach 165°F (74°C).
Try a Different Cheese
Swiss cheese gives the casserole its mild, nutty character, but you can experiment with shredded mozzarella, Monterey Jack, or mild cheddar. Each option creates a slightly different flavor and texture.
Add a Little Garlic
For a more savory finish, sprinkle garlic powder or onion powder over the chicken before adding the soup. These additions keep preparation simple while adding extra depth.
Add Vegetables
For a more substantial meal, serve the chicken alongside steamed broccoli, peas, or green beans. You can also experiment with a layer of suitable vegetables in the casserole, keeping in mind that extra ingredients may change the amount of moisture and the cooking time.
Make It a Complete Casserole
For an all-in-one dinner, serve the chicken over cooked rice or egg noodles, or incorporate cooked rice into a suitably sized baking dish. Adding extra ingredients changes the original three-ingredient recipe, so make sure everything is heated through before serving.
Make-Ahead and Storage Instructions
Can You Prepare Chicken Delmonico Ahead of Time?
Yes. You can assemble the chicken, soup, and cheese in the baking dish a few hours ahead. Cover the dish and refrigerate it until you’re ready to cook.
For food safety, keep the assembled casserole refrigerated rather than leaving raw chicken at room temperature. Because a chilled casserole may take longer to heat through, rely on the chicken’s internal temperature instead of the original baking time alone.
If your baking dish is made of glass or ceramic, follow the manufacturer’s instructions about temperature changes to reduce the risk of cracking.
How to Store Leftovers
Allow leftovers to cool promptly, then transfer them to an airtight container and refrigerate within two hours of cooking. Enjoy within 3–4 days.
How to Reheat
Reheat individual portions in the microwave until steaming hot throughout, or place the leftovers in an oven-safe dish and warm them in a 325°F (165°C) oven. Cover loosely with foil if the cheese is browning too quickly.
Add a small splash of milk or broth if the sauce has thickened during storage. Reheated leftovers should reach 165°F (74°C).
What to Serve with Chicken Delmonico
Because this casserole is creamy, savory, and rich, it pairs especially well with simple sides that balance its flavor and make the sauce go further.
– Creamy mashed potatoes: A classic pairing that catches every spoonful of the chicken sauce.
– Buttered egg noodles: Tender noodles make a comforting base for the creamy chicken.
– Steamed white rice: A simple, budget-friendly option that soaks up the sauce.
– Green beans or buttered peas: These vegetables add freshness and color to the plate.
– Roasted broccoli: A lightly browned vegetable adds texture and balances the rich cheese.
– Crisp garden salad: Lettuce, cucumber, and a tangy dressing provide a refreshing contrast.
– Warm dinner rolls: Soft rolls are perfect for scooping up the remaining sauce.
For a traditional family-style meal, serve the chicken with mashed potatoes, green beans, and warm rolls. If you’re preparing a quick weeknight supper, rice and a simple salad make an easy combination.
Frequently Asked Questions
Why Is It Called Chicken Delmonico?
The name Chicken Delmonico has been used for different chicken preparations, and recipes can vary. This version is a simple home-style casserole made with chicken, condensed cream of chicken soup, and Swiss cheese. The name here identifies this particular family-style recipe rather than suggesting that every dish called Chicken Delmonico uses the same ingredients.
Can I Use Frozen Chicken?
For the most reliable results, thaw chicken completely in the refrigerator before assembling the casserole. Baking frozen chicken in this dish can cause uneven cooking and make the cooking time difficult to predict.
Should I Cover the Casserole While Baking?
No. This recipe is baked uncovered so the cheese can melt and the top can develop some golden color. If the cheese starts browning too quickly before the chicken is cooked, loosely cover the dish with foil.
How Do I Keep the Chicken From Drying Out?
Use chicken pieces of similar thickness, start checking for doneness early, and remove the casserole once the thickest piece reaches 165°F (74°C). Overcooking is one of the most common reasons baked chicken turns dry.
Can I Use Another Condensed Soup?
Yes. Condensed cream of mushroom soup can work as an alternative, although it changes the flavor. The original version uses cream of chicken soup for a familiar, savory taste.
Is This Really a Three-Ingredient Recipe?
Yes. The main ingredients are chicken, condensed cream of chicken soup, and shredded Swiss cheese. Butter or cooking spray for greasing the dish is used only to prepare the pan, and optional seasonings or side dishes are not required for the basic recipe.
