What You Need

Check the full printable recipe card below for detailed measurements and the complete list of everything you’ll need to create this culinary masterpiece.

Expert Tips
- Shred Your Chicken Perfectly: For the most tender results, use cooked chicken that’s either shredded by hand or, my favorite hack, shredded using a stand mixer! Simply place warm, cooked chicken pieces in the bowl of your stand mixer with the paddle attachment and mix on low until shredded. It’s quick and effortless!
- Don’t Skip Draining the Spinach: Fresh spinach releases a lot of water as it wilts. After cooking, make sure to squeeze out as much excess liquid as possible. This prevents your casserole from becoming watery and ensures a rich, creamy texture. A clean kitchen towel or a fine-mesh sieve works wonders here.
- Soften Your Cream Cheese: For a silky-smooth sauce without any lumps, ensure your cream cheese is at room temperature before mixing. This allows it to incorporate seamlessly with the other liquid ingredients, creating that irresistible creamy base.
- Build Flavor Layers: Don’t be shy with seasoning! Sautéing onions and garlic until fragrant builds a delicious aromatic foundation. A pinch of nutmeg might sound unusual, but it enhances the creaminess and brings out the best in the spinach – a secret ingredient that truly makes a difference.
- Cheese Blend for Best Texture: While cheddar is fantastic for flavor, adding a bit of mozzarella or Monterey Jack gives a wonderful melt and stretch. Don’t be afraid to experiment with your favorite cheese combinations for an extra layer of yumminess.
- Prevent Overcooking the Chicken: Since you’re using pre-cooked chicken, the goal in the oven is simply to heat through and melt the cheeses. Overbaking can dry out the chicken, so keep an eye on it. The casserole is ready when it’s bubbly around the edges and the cheese on top is golden.
- Consider Your Dish Size: A 9×13 inch baking dish is ideal for this recipe, allowing for even heating and a good crust-to-creamy-filling ratio. If using a smaller dish, be mindful of overflow and adjust baking time if the casserole is deeper.
- Let It Rest: I know it’s tempting to dig in immediately, but allowing the casserole to rest for 5-10 minutes after baking helps the sauce set and makes for cleaner, easier serving. This brief resting period ensures that every slice holds its shape beautifully.
- Add a Topping for Texture: For an extra layer of deliciousness and crunch, consider adding a sprinkle of crushed crackers, panko breadcrumbs, or even a handful of crushed crispy fried onions mixed with melted butter during the last 10 minutes of baking.
- Meal Prep Savvy: This recipe is a dream for meal prep! You can assemble the entire casserole, cover it tightly, and refrigerate it for up to 24 hours before baking. Just add an extra 5-10 minutes to the baking time if cooking from cold.
Variations & Substitutions
This casserole is incredibly versatile, making it easy to adapt to different tastes or dietary needs.
- Keto/Low-Carb: Omit any pasta if you include it (my primary recipe won’t, but some versions do) and ensure no starchy binders. Serve it as is, or over riced cauliflower or zucchini noodles. You can also add more low-carb vegetables like mushrooms or bell peppers.
- Gluten-Free: This recipe is naturally gluten-free if you ensure your broth is GF. If you decide to add a flour-based roux for thickening, use a gluten-free all-purpose flour blend.
- Add More Veggies: Feel free to stir in sautéed mushrooms, diced bell peppers, corn, or even a handful of frozen peas for extra color and nutrition. Just make sure to pre-cook any harder vegetables before adding them to the mixture.
- Different Proteins: Not a fan of chicken? Cooked turkey, shredded pork, or even firm white fish (like cod, flaked) could work. For a vegetarian option, consider using cannellini beans or a plant-based chicken substitute along with vegetable broth.
- Spice It Up: Add a pinch of red pepper flakes to the sauce for a subtle kick, or a dash of hot sauce if you prefer more heat.
- Herbaceous Notes: Fresh herbs like chopped parsley, chives, or a hint of thyme can add another layer of fresh flavor. Stir them in just before baking.

Storage & Freezing
One of the best things about this casserole is how well it stores, making it perfect for leftovers or future meals!
- Refrigerating Leftovers: Allow the casserole to cool completely. Transfer any leftovers to an airtight container and store in the refrigerator for up to 3-4 days.
- Reheating: To reheat individual portions, simply microwave until warmed through. For larger portions, cover with foil and reheat in an oven preheated to 300°F (150°C) until bubbly, about 20-30 minutes.
- Freezing: This casserole freezes beautifully!
- To Freeze Unbaked: Assemble the casserole completely in a freezer-safe dish (aluminum foil pans work great). Cover tightly with plastic wrap, then with aluminum foil. Freeze for up to 3 months. When ready to bake, thaw overnight in the refrigerator, then bake as directed, possibly adding an extra 10-15 minutes to the cooking time.
- To Freeze Baked: Allow the baked casserole to cool completely. You can freeze it whole, or portion it into individual servings in freezer-safe containers. Cover tightly and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat as directed above.
FAQ
Q: Can I use frozen spinach instead of fresh?
A: Yes, you absolutely can! If using frozen spinach, make sure to thaw it completely and squeeze out as much excess water as possible. This is a crucial step to prevent a watery casserole. About 10 ounces of frozen spinach, once squeezed, is roughly equivalent to 1 pound of fresh spinach.
Q: What kind of chicken is best for this casserole?
A: Cooked shredded chicken is ideal. You can use leftover roast chicken, rotisserie chicken for a super quick option, or boil/bake some chicken pieces (like boneless, skinless chicken fillets or thighs) specifically for the recipe. Using already cooked chicken saves a lot of time!
Q: Can I make this casserole ahead of time?
A: Yes, it’s perfect for making ahead! Assemble the entire casserole, cover it tightly with plastic wrap and then foil, and refrigerate for up to 24 hours before baking. When ready to cook, let it sit at room temperature for about 30 minutes while your oven preheats, then bake as directed, potentially adding a few extra minutes to ensure it’s heated through.
Q: My casserole turned out a bit watery. What went wrong?
A: The most common culprit for a watery casserole is not fully draining the spinach. Fresh or thawed frozen spinach holds a lot of moisture, so it’s essential to squeeze out every drop after cooking. Over-diluting the sauce with too much milk or broth can also contribute, so stick to the recipe measurements.
