Cheesy Chicken and Rice Casserole combines cooked chicken and rice with a creamy homemade cheddar sauce for an easy, family-friendly dinner made without canned soup.
Arrange a rack in the center of the oven and preheat to 350℉ (175℃). Lightly grease a 9x13-inch baking dish with butter.
In a large saucepan, melt 4 tablespoons unsalted butter over medium-high heat. Whisk in ¼ cup all-purpose flour and cook for 1 minute, whisking constantly, to cook off the raw flour taste.
Slowly whisk in ¼ cup dry white wine (or additional broth). Add ½ tablespoon minced garlic and cook briefly until thickened and fragrant.
Slowly stream in 2 cups low-sodium chicken broth, whisking to incorporate. Season with 1 teaspoon kosher salt, 1 teaspoon black pepper, and ½ tablespoon fresh chopped thyme (if using), and bring the mixture to a light bubble. Simmer, whisking often, until the sauce has thickened enough to coat the back of a spoon, about 3-4 minutes.
Reduce the heat to low and stir in 2 cups shredded cheddar cheese until melted and smooth.
Turn off the heat and stir in 4 cups cooked rice and 2 cups cooked chicken (diced or shredded) until the chicken and rice are evenly coated with the sauce.
Transfer the chicken and rice mixture to the buttered 9×13-inch baking dish. Top with the remaining 1½ cups shredded cheddar cheese.
Bake uncovered for 25-30 minutes, until the casserole is heated through and the cheese is melted.

Notes
Thyme Leaves: If you don't have fresh thyme, substitute it with ½ teaspoon of dried thyme leaves or omit altogether. Do not use ground thyme. The flavor is overwhelming. Wine: Replace it with an additional ¼ cup chicken broth if desired. If using wine, choose a dry Sauvignon Blanc or Pinot Grigio.Garlic: This casserole leans fairly garlicky as written. Feel free to cut the amount in half or omit it entirely.Storage: Store leftover chicken and rice casserole in a covered container for up to 3 days in the refrigerator. Alternatively, freeze in a freezer-safe container for up to 3 months. Make-Ahead Instructions: Assemble in an oven-safe, freezer-safe baking dish. Cover tightly with 2 layers of foil.
