Can I use fresh chicken instead of frozen popcorn chicken?
Yes. Use cooked shredded chicken or diced cooked breasts (about 3 cups). Mix into the casserole or layer as directed; reduce baking time by 10–15 minutes since the chicken is already cooked.
How do I make this ahead?
Assemble the casserole completely, cover tightly with plastic wrap, and refrigerate up to 24 hours. Bake from cold, adding 10–15 minutes to the baking time.
What if I don't have brown gravy?
Make gravy from pan drippings or use canned chicken gravy, beef gravy, or even cream of mushroom soup thinned with a little broth for a different but equally comforting finish.
Can I double this recipe?
Yes. Double all ingredients and use a 9x13-inch casserole dish (or two 8x8-inch dishes). Baking time may increase by 10–15 minutes; check that the cheese is bubbly and edges are set.
Is this gluten-free?
Mostly, if using gluten-free popcorn chicken and gluten-free brown gravy. Always check product labels, as some brands contain gluten.
