Key Ingredients for Million Dollar Chicken Casserole

See recipe card below for full list of measurements, ingredients, and instructions.

Cooked Chicken

This is the heart of the casserole, providing hearty protein and a satisfying bite. Use rotisserie chicken for major convenience, or leftover roast chicken for extra flavor. Shredding or chopping into bite-sized pieces works best. For a fun twist, you can even use leftover turkey!

Cream Cheese

Cream cheese makes the sauce decadently creamy and gives the casserole its signature “million dollar” richness. Let it soften at room temperature for easy mixing. You can substitute Neufchâtel for a lighter option, but don’t skip it entirely—it’s key to that luscious texture!

Sour Cream

Sour cream adds a subtle tang that balances all the cheese and creaminess. Use full-fat for the richest result, but light sour cream works in a pinch. Greek yogurt is a great substitute if you want to bump up the protein.

Shredded Cheeses (Mozzarella & Parmesan)

A duo of mozzarella and parmesan creates gooey meltiness and a salty, nutty finish. Pre-shredded cheese is fine for convenience, but shredding your own really amps up the flavor and melting power. Swap in Monterey Jack or sharp cheddar if you like!

Ritz Crackers

Crushed Ritz crackers form the irresistible buttery topping that gets golden and crisp in the oven. If you need a gluten-free version, try crushed GF crackers or cornflakes. Panko breadcrumbs also work, but the crackers add that classic flavor.

Instructions for Million Dollar Chicken Casserole

See recipe card below for full list of measurements, ingredients, and instructions.

Prep Your Oven and Baking Dish

Start by preheating your oven to 350°F (175°C). Grease a 9x13-inch baking dish with cooking spray or a little butter—this helps prevent sticking and makes serving a breeze.

Mix Up the Creamy Chicken Filling

In a large mixing bowl, combine the softened cream cheese, sour cream, mozzarella, parmesan, minced garlic, onion powder, Italian seasoning, salt, and pepper. Stir until smooth and creamy, then fold in the cooked chicken so it gets evenly coated.

Assemble the Casserole

Spread the creamy chicken mixture evenly into your prepared baking dish. Use a spatula to smooth the top so you get that perfect crust later on.

Make the Buttery Cracker Topping

In a small bowl, combine the crushed Ritz crackers and melted butter. Toss until all the cracker crumbs are nicely coated—this is the secret to that crispy, golden topping! Sprinkle the mixture evenly over the casserole.

Bake to Golden Perfection

Bake the casserole uncovered for 25–30 minutes, or until the top is golden brown and the edges are bubbling. For an extra-crispy top, you can broil the last 1–2 minutes, but watch closely so it doesn’t burn.

Garnish and Serve

Let the casserole cool for 5 minutes before serving. Sprinkle with a little chopped fresh parsley for a pop of color, and enjoy your million dollar moment!

Recipe Variations

Add a Veggie Boost

Stir in 1 cup of thawed frozen peas, chopped steamed broccoli, or sautéed spinach for extra color and nutrition. It’s an easy way to sneak in veggies for the whole family!

Spice It Up

Like a little heat? Add a pinch of red pepper flakes or a dash of hot sauce to the creamy chicken mixture. You could also mix in diced green chilies or jalapeños for a Southwest twist.

Make It Gluten-Free

Swap the Ritz crackers for gluten-free crackers or crushed cornflakes for a celiac-friendly version. Double-check all your other ingredients (especially the chicken broth, if adding any) to ensure they’re gluten-free.

Lighten It Up

Use Neufchâtel cheese instead of regular cream cheese, light sour cream, and part-skim mozzarella for a lighter take without losing that signature creaminess.

Swap the Protein

Turkey, rotisserie chicken, or leftover roasted pork all work wonders in this casserole—perfect for using up holiday leftovers! For a vegetarian spin, try cooked chickpeas or a plant-based chicken substitute.

Serving Suggestions

Pair this Million Dollar Chicken Casserole with a crisp green salad tossed in a bright vinaigrette or some simple roasted vegetables. For an extra-comforting meal, serve alongside fluffy mashed potatoes, steamed green beans, or classic Southern-style biscuits. Don’t forget a sprinkle of extra parmesan and parsley for that finishing touch!

Storage and Reheating

Leftovers? No problem! Let the casserole cool completely, then cover tightly and refrigerate for up to 4 days. To reheat, simply scoop portions into a microwave-safe dish and heat on medium power until hot, or rewarm in a 350°F oven for 15–20 minutes until bubbly.

Want to freeze it? Assemble the casserole (without baking), cover tightly with foil, and freeze for up to 2 months. Bake directly from frozen at 350°F, adding 15–20 extra minutes, or thaw overnight before baking as directed. The cracker topping may soften slightly after freezing, but a quick broil will help crisp it back up!
