Before you start
Before beginning, ensure the chicken is removed from the refrigerator about 20 minutes prior to cooking to take the chill off. This helps the meat cook more evenly. Preheat your oven fully to 375°F (190°C) before placing the dish inside.
Have your baking dish ready and clear a space on your counter for the chicken. Ensure your meat thermometer is clean and calibrated, as it is the most reliable tool for confirming that the chicken is perfectly cooked and safe to eat.

Instructions
Preparation
- Prepare the ChickenPreheat the oven to 375°F (190°C). Place the chicken breasts into a baking dish in a single layer.Look for Chicken is arranged in the dish.Tip Ensure the chicken breasts are of similar thickness to promote even cooking throughout the baking process.
The chicken breasts should be arranged in a single layer in the baking dish. They should be at a consistent temperature to ensure they cook at the same rate, and the baking dish should be prepared for the oven. Check that the oven has reached the correct temperature before proceeding to the next step.
Sauce and Cheese Application
- Add Creamy Sauce and CheeseSpread the sour cream evenly over the top of each chicken breast. Sprinkle the shredded mozzarella cheese generously over the sour cream layer to ensure full coverage.Look for Chicken is fully coated with cream and cheese.Tip Using a spatula helps to spread the sour cream evenly without disturbing the chicken pieces in the dish.
The sour cream must be spread in a uniform layer across all pieces of chicken, and the mozzarella should cover the top completely. Ensure that the edges of the chicken are covered to prevent them from drying out. The dish should look uniform, with the cheese ready to melt into the creamy base during the baking phase.
Baking and Resting
- Bake and ServePlace the baking dish into the oven and bake for 25 to 30 minutes. Verify the chicken has reached an internal temperature of 165°F (74°C). Remove from the oven, let the meat rest for 5 minutes, then serve.Look for Cheese is melted and golden, chicken is cooked through.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Always check the temperature at the thickest part of the chicken breast to ensure it is cooked safely.
The chicken is ready when the cheese is melted, golden, and bubbly, and the internal temperature has reached 165°F (74°C). The sauce should appear thickened and integrated with the cheese.
Once removed from the oven, the chicken must rest for 5 minutes to allow the juices to redistribute throughout the meat, ensuring a tender final result.
Common mistakes
A common mistake is using chicken breasts that vary wildly in thickness, which leads to uneven cooking where some parts are dry while others remain undercooked.
Another error is failing to ensure the oven is fully preheated; the chicken needs a consistent environment to cook through properly. Finally, avoid using high-heat settings, as this may brown the cheese too quickly before the chicken has a chance to cook through internally.
How to tell it’s done
The chicken is done when the internal temperature reaches 165°F (74°C) as measured by a meat thermometer inserted into the thickest part of the breast. Visually, the cheese should be bubbling and slightly browned in spots, and the sour cream sauce should be hot and bubbly around the edges of the dish.
Avoid overcooking, as even with the protective sauce, lean chicken breast can become tough if left in the oven for too long after reaching the target temperature.
