Ingredients and Substitutions

CHICKEN THIGHS Chicken thighs are just the right size for eating! Two pounds of skinless (bone-in) thighs feeds up to 4 people, however, boneless, skinless chicken breasts can also be used. Simply cut them into 2” pieces and follow the recipe as directed. And if time is really short, replace the chicken entirely with a bag of frozen meatballs-no need to thaw!

SAUCE AND VEGGIES The secret to this amazing sauce is a jar of Alfredo sauce mixed with broth and mustard. If Alfredo sauce isn’t readily available, use three cans of cream of mushroom, chicken, or celery soup. Punch up the flavor with some minced garlic and red chili peppers!

MUSTARD Grainy mustard has whole mustard seeds in it which punches up the flavor and adds visual appeal to the sauce. Stone ground, Dijon, or spicy brown mustards will work, too.

CHEESE Parmesan cheese thickens the sauce at the end, but shredded Swiss cheese or crumbled feta melts well and tastes delicious!

    1. I haven’t tried cooking chicken thighs from frozen in this recipe so I can’t for sure say how it would work. You can try defrosting in cold water which is the best way for same day defrosting. Regardless make sure to cook your chicken to 165°F.

  1. this was awesome! such an easy recipe and so delish. I accidentally put my instant pot on high instead of low, but it was fine because it was done in just over an hour. I paired this with a whole wheat linguine. will definitely be a staple from now on!

    1. Depending on the size of your chicken thighs it should take roughly the same amount of time. You will want to make sure they reach a safe internal temperature of 165˚F before serving.
