Why This Recipe Works (Quick Science)

Chicken thighs have more fat than chicken breasts, so they stay juicy during slow cooking. The tomatoes slowly break down and mix with the chicken juices to make a rich sauce. Heavy cream and parmesan cheese help thicken the sauce and make it creamy. Cooking low and slow also gives the garlic and herbs time to build deep flavor.

Pro Tips

Brown the chicken first if you have extra time. It adds a deeper flavor.
Don’t lift the slow cooker lid too often. Heat escapes every time you open it.
Stir the parmesan in slowly so it melts smoothly into the sauce.
Slice the mushrooms evenly so they cook at the same speed.
Let the chicken rest in the sauce for 5 minutes before serving for the best flavor.

Substitutions and Variations

Use chicken breasts instead of thighs if preferred
Add spinach during the last 15 minutes
Swap mushrooms for zucchini or bell peppers
Use half-and-half instead of heavy cream
Add crushed red pepper flakes for heat

Make Ahead Tips

Dice the onion and mushrooms one day ahead
Mix the seasonings ahead of time
Store all ingredients in the fridge until ready to cook

Common Mistakes

Using frozen chicken can water down the sauce
Adding cream too early may cause curdling
Overcooking the chicken can make it dry
Skipping seasoning makes the sauce taste flat
Opening the lid too much slows cooking time

Buttered pasta
Garlic bread
