1. Preheat your oven to 350°F (175°C) and grease a 9×13 inch casserole dish with butter or cooking spray. Don’t skip greasing it or you’ll have a cleanup nightmare.
2. In your largest mixing bowl, combine the cream of chicken soup and milk. Whisk them together until smooth and lump-free—this is your creamy sauce base.
3. Add the shredded cooked chicken, frozen mixed vegetables (no need to thaw), three-quarters of the shredded cheddar cheese (save a handful for topping), garlic powder, onion powder, salt, and pepper. Mix everything together until well combined.
4. Fold in the cooked rice until it’s evenly distributed throughout the mixture. The mixture should look creamy and thick, not soupy. If it seems too thick, add a splash more milk.
5. Pour the mixture into your prepared casserole dish and spread it out evenly with a spatula, making sure to get it into the corners.
6. Sprinkle the reserved cheese over the top—this creates that gorgeous golden, bubbly crust everyone fights over.
7. Cover the dish tightly with aluminum foil and bake for 30 minutes. This lets everything heat through without drying out.
8. Remove the foil and bake for an additional 10-15 minutes until the top is golden brown and bubbly. You want that cheese melted and slightly crispy at the edges.
9. Let it cool for about 5 minutes before serving—this helps it set up so you get nice portions instead of a soupy mess. I know nobody wants to wait, but it’s worth it!
10. Serve hot and watch it disappear!

Notes:

• Day-old rice works better than fresh because it’s drier and won’t make the casserole mushy

• If your mixture seems dry, add a little more milk before baking
• Every oven is different, so watch it during the final uncovered baking and adjust time as needed
• Covering with foil for the first 30 minutes prevents the top from drying out while the inside heats through
