Pat the chicken breasts dry with paper towels.
If they're especially thick, gently flatten them so they're closer to an even thickness throughout.
This isn't absolutely necessary, but it can help prevent the thinner portions from becoming overcooked while the center finishes cooking.
2. Make the Sauce
In a bowl, combine the condensed cream of mushroom soup with the dry onion soup mix.
Stir until the seasoning is evenly distributed.
The mixture will be thick, which is exactly what you want. As the chicken cooks, its moisture helps create a more spoonable sauce.
3. Assemble the Dish
Place the chicken breasts in a lightly greased baking dish.
Spread the mushroom and onion mixture evenly over the chicken, making sure the pieces are well coated.
4. Bake
Cover the dish with foil and bake at 350°F (175°C) until the chicken is cooked through.
The exact cooking time will depend on the thickness of the chicken breasts, so don't rely on time alone. Chicken should reach an internal temperature of 165°F (74°C) in the thickest part.
If you want a little browning on top, remove the foil during the final portion of baking.
5. Rest and Serve
Allow the chicken to rest for a few minutes before serving.
Spoon some of the creamy mushroom-onion sauce over each piece of chicken and serve immediately.
The Best Sides for Tavern Chicken
Because the sauce is rich and savory, this chicken pairs beautifully with simple sides.
Try serving it with:
- Creamy mashed potatoes
- Buttered egg noodles
- White or brown rice
- Roasted potatoes
- Steamed green beans
- Glazed carrots
- Roasted broccoli
- Corn
- A crisp green salad
- Crusty dinner rolls
Mashed potatoes are especially good because they soak up the creamy sauce.
Tips for the Best Results
Don't Skip the Meat Thermometer
Chicken breasts can vary dramatically in size. A meat thermometer is the most reliable way to determine when they're done.
Insert it into the thickest part of the chicken and make sure it reaches 165°F (74°C).
Don't Overbake
Chicken breast is lean, so excessive cooking can make it dry.
Once the chicken reaches the safe internal temperature, remove it from the oven and let it rest.
Use Evenly Sized Chicken
If one breast is much thicker than the others, it may take considerably longer to cook. Flattening or slicing particularly large breasts can help everything finish at roughly the same time.
Let the Sauce Do the Work
There's no need to add a long list of seasonings. The onion soup mix already contributes a concentrated savory flavor, while the mushroom soup creates the creamy sauce.
Easy Variations
The three-ingredient version is delicious on its own, but you can easily change it when you have additional ingredients available.
Add Mushrooms
For extra mushroom flavor and texture, add sliced fresh mushrooms to the baking dish.
Add Cheese
Sprinkle shredded cheddar, Monterey Jack, or Swiss cheese over the chicken during the final few minutes of baking.
Add Garlic
A little minced garlic or garlic powder can give the sauce an additional savory note.
Add Vegetables
Sliced onions, broccoli, green beans, or bell peppers can turn the dish into a more complete one-pan meal. Make sure any added vegetables have enough time to cook properly.
Use Chicken Thighs
Boneless, skinless chicken thighs are another option. They contain more fat than chicken breasts and tend to stay juicy during longer cooking.
Cooking time will vary, so always check the internal temperature rather than relying solely on the clock.
Can You Make Tavern Chicken in a Slow Cooker?
You can adapt creamy chicken recipes for a slow cooker, but cooking times and liquid requirements differ from oven preparation.
If you choose the slow-cooker method, use a recipe specifically designed for that appliance or adjust the ingredients and cooking process appropriately. Most importantly, make sure the chicken reaches 165°F (74°C) before serving.
For the simplest and most predictable version of this particular recipe, the oven method is an excellent choice.
How to Store Leftovers
Allow leftover chicken to cool and refrigerate it promptly in a covered container.
Keep the chicken and sauce together so the meat stays moist.
For best quality, reheat gently until the chicken is thoroughly hot. If the sauce has thickened in the refrigerator, a small splash of milk or broth can help loosen it.
Frequently Asked Questions
Can I use chicken thighs instead of breasts?
Yes. Boneless, skinless chicken thighs are a good substitute and tend to be particularly juicy. Because they're a different cut, cooking time will vary.
Can I use a different condensed soup?
Cream of chicken soup can be substituted for cream of mushroom soup if you prefer. The flavor will change, but the creamy texture will still work well with the onion seasoning.
Is onion soup mix enough seasoning?
For the basic three-ingredient recipe, yes. Onion soup mix is designed to provide concentrated seasoning and helps give the sauce its savory character.
Why is my sauce so thick?
Condensed soup is naturally thick. As the chicken cooks, moisture is released into the dish, thinning the sauce. If necessary, you can stir in a small amount of milk or broth before baking.
How do I know when the chicken is done?
Use an instant-read thermometer in the thickest portion. Chicken should reach an internal temperature of 165°F (74°C).
