Before you start
Before starting, ensure the chicken breasts are thawed if frozen. Slice the cremini mushrooms and measure the soup, cheese, and butter. Have a 6-quart slow cooker ready.
If serving with pasta, cook the penne according to package directions, drain, and toss with garlic butter. Keep the cooked pasta warm until the chicken is ready.
Ingredients at a glance (6)
- 1 1/2 lb boneless skinless chicken breasts
- 8 oz cremini mushrooms, sliced
- 1 can (10.5 oz) condensed cream of mushroom soup
- 1 1/2 cups shredded whole-milk mozzarella cheese
- 2 tbsp garlic herb butter
- 8 oz garlic butter penne pasta, cooked
Instructions
Layer and Set
- Layer the IngredientsPlace the chicken breasts in the bottom of a 6-quart slow cooker in a single layer. Scatter the sliced cremini mushrooms evenly over the chicken. Spoon the condensed cream of mushroom soup over the top, spreading it to cover the chicken and mushrooms as much as possible.Look for The chicken is covered with mushrooms and soup, creating a thick, creamy base.Tip Use a spatula to spread the soup evenly so it coats the chicken and mushrooms.
- Add Cheese and ButterSprinkle the shredded mozzarella cheese evenly over the soup layer. Dot the top with the garlic herb butter, placing the pats in different spots so the flavor melts throughout.Look for The cheese forms a snowy layer over the soup, with butter pats melting on top.Tip If using homemade garlic herb butter, let it soften slightly for easier dotting.
At the end of this phase, the slow cooker contains raw chicken, mushrooms, soup, cheese, and butter. The ingredients are layered neatly, with the cheese and butter on top.
The soup is evenly spread, and the butter pats are visible. No cooking has started yet, so the dish looks like a colorful, uncooked casserole.
Slow Cook and Shred
- Slow Cook Until TenderCover the slow cooker and cook on LOW for 4 to 5 hours, or on HIGH for 2 to 3 hours, until the chicken is cooked through and tender. The sauce will be bubbling and the cheese melted.Look for The sauce is gently bubbling around the edges, and the chicken feels tender when pressed.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Avoid lifting the lid during cooking—it releases heat and extends the cooking time.
- Shred the ChickenUsing two forks, shred the chicken directly in the slow cooker. Stir the shredded chicken into the sauce until everything is well combined and coated. The chicken should reach an internal temperature of 165°F (74°C).Look for The chicken shreds easily and is fully absorbed into the creamy sauce.Safe temperature 165°F (74°C) internal temperature (poultry)Tip For larger shreds, pull gently; for finer shreds, use a quick motion.
After cooking, the sauce is bubbling gently around the edges, and the cheese has melted into a creamy sauce. The chicken is fork-tender and easily shreds. The aroma of garlic and mushrooms fills the kitchen. The sauce should be thick enough to coat a spoon, with no raw flour taste from the soup.
Serve
- Serve Over PastaSpoon the creamy mozzarella mushroom chicken over the cooked garlic butter penne pasta. Serve hot, with extra sauce spooned over the top.Look for The sauce is thick and creamy, clinging to the pasta and chicken.Tip For a lighter option, serve over steamed rice or cauliflower rice.
The shredded chicken is fully mixed into the sauce, which is creamy and smooth with bits of mushroom throughout. When spooned over pasta, the sauce clings to the noodles, and the dish looks rich and inviting. The chicken is moist and flavorful, and the mozzarella provides a subtle stretch.
Common mistakes
Avoid lifting the lid during cooking to check on the chicken—this releases heat and prolongs cooking time. Do not overcook, as chicken breasts can become dry; stick to the recommended times.
If using pre-shredded mozzarella, it may not melt as smoothly; shredding your own cheese ensures a creamier sauce. Also, resist the urge to add extra liquid—the soup and chicken juices provide enough moisture.
How to tell it’s done
The dish is done when the chicken is cooked through and reaches an internal temperature of 165°F (74°C) on an instant-read thermometer. The sauce should be bubbling and slightly thickened, with the cheese fully melted and incorporated.
Shred the chicken with two forks—it should pull apart easily and be tender throughout. If the sauce seems thin, let it cook uncovered for an additional 15–20 minutes to reduce.
- Poultry: 165°F (74°C) in the thickest part
