We talk about Costco a lot, and while we love their legendary bakery section as much as anyone, the real best value at Costco has got to be its rotisserie chicken. Who hasn’t taken a discreet car nibble of a rotisserie chicken leg after a long shopping trip, overcome by the savory aroma? But even better is having the chicken in the fridge at home, just waiting to be tranformed into a cozy, comforting recipe the whole family will love.
These chicken casseroles can be made even easier if you use leftover Costco rotisserie chicken. They’re full of protein, but most importantly, taste great without requiring hours of work. Add an extra rotisserie chicken to your cart the next time you’re at Costco (sign up for a membership here), and dinner will be easier than ever.
