Why You’ll Love This Classic Creamy Chicken and Spinach Casserole

This recipe is a time-saving gem. You can use rotisserie chicken, frozen spinach, or leftover veggies you have on hand. It’s also perfect for meal prepping since it reheats beautifully.

Both work great! Fresh spinach gives a brighter, slightly more delicate texture, while frozen spinach is super convenient and still packs all the flavor. Just be sure to squeeze out any extra moisture if you go the frozen route to avoid a watery casserole.

How To Make the Classic Creamy Chicken and Spinach Casserole

Step 1: Preheat and Prepare

Preheat your oven to 375°F. Lightly grease a 9×13 baking dish and set it aside.

Step 2: Sauté Aromatics

In a skillet, sauté diced onion in a splash of olive oil until translucent. Add minced garlic and cook for another minute until fragrant.

Step 3: Mix the Filling

In a large bowl, combine cooked chicken, spinach (make sure it’s well-drained if using frozen), cream of chicken soup, sour cream, sautéed onions and garlic, half of the shredded cheese, salt, and pepper. Stir everything together until well mixed.

Step 4: Assemble

Transfer the mixture to the prepared baking dish. Spread it out evenly. Sprinkle the remaining cheese on top. If you want a little crunch, add breadcrumbs over the cheese.

Step 5: Bake

Bake uncovered for about 25 to 30 minutes, or until the cheese is melted and bubbly and the casserole is heated through.

Step 6: Serve

Let it rest for 5 minutes before serving to allow it to set. Then dig in!
