Every time I open the oven to that scent of bubbling cheese and beef bacon my son rushes in asking for the first scoop The golden potato corners are always his favorite part

Storage Tips

Let the casserole cool to room temperature before storing Slice into squares before packing into airtight containers It keeps well in the fridge up to three days For longer storage wrap portions tightly and freeze for up to two months Reheat slow and gentle in the oven to keep the texture creamy

Ingredient Substitutions

Swap sweet potatoes if you want a touch of earthy sweetness Turkey bacon or regular bacon slices work if you do not have beef bacon For extra veggies fold in steamed broccoli or corn alongside the chicken Use Monterey Jack or Gruyere in place of cheddar for a different flavor

Serving Suggestions

Serve this casserole with a big green salad for balance For even more richness top each plate with a dollop of extra sour cream or a few dashes of hot sauce Steamed broccoli or roasted green beans on the side work great too In our house dinner is always followed by a bowl of crispy apple slices to cut through the richness
