This easy-to-make casserole layers tender shredded chicken, crisp-tender broccoli, and white rice, all bound together in a rich, creamy sauce made with condensed soup, sour cream, mayonnaise, and lemon juice. Topped with sharp Cheddar, it's baked until bubbly and golden, offering a comforting and hearty meal for up to 10 servings.
For the chicken, consider poaching rather than a long boil to maintain moisture and tenderness; a shorter simmering time (20-25 minutes) until an internal temperature of 165°F (74°C) is reached will prevent dryness. Freshly grate the Cheddar for superior melt and flavor, as pre-shredded cheese often contains anti-caking agents. Ensure broccoli is truly crisp-tender; overcooked broccoli becomes mushy. A pinch of smoked paprika or garlic powder in the sauce can add depth. Allow the casserole to rest for the full 5 minutes after baking to allow the sauce to set, preventing a runny consistency upon serving.
