The creamy chicken and spinach casserole is a comforting, flavorful dish that combines tender chicken, melted cheese, and fresh spinach in a rich, creamy sauce. This casserole is perfect for both busy weeknights and special gatherings, as it’s simple to prepare yet deliciously satisfying. With ingredients like garlic, Italian seasoning, and a blend of cream cheese and mozzarella, the flavors meld together beautifully, making each bite rich and savory.

What makes this casserole so appealing is its versatility. It can be a wholesome family meal served with a side of crusty bread or a salad, or it can be doubled for larger gatherings where you want to impress with minimal effort. It’s also easy to customize by adding vegetables or adjusting the spices, making it suitable for a variety of tastes. This casserole is the perfect blend of convenience and comfort food, ideal for any occasion.

For this creamy chicken and spinach casserole, choosing the right ingredients is key to achieving a delicious, satisfying dish. Chicken is the star of the casserole, and boneless, skinless chicken breasts are an excellent choice due to their lean quality and ease of preparation. They cook quickly and evenly, especially when sliced into thin cutlets, ensuring a tender texture that pairs well with the creamy sauce.

Olive oil plays a dual role in this recipe: it helps marinate the chicken, allowing flavors to seep in, and also acts as a cooking medium for wilting the spinach. Its mild, fruity flavor complements the richness of the cheese and chicken without overpowering the dish.

Garlic and Italian seasoning bring the casserole to life with their aromatic and savory notes. Italian seasoning, with its blend of herbs like basil, oregano, and thyme, enhances the natural flavors of chicken and spinach, adding warmth and depth to each bite.

Fresh spinach adds a nutrient-rich layer to the casserole, providing vitamins, minerals, and fiber. Fresh spinach has a vibrant flavor and color that elevate the dish’s presentation and taste.

Finally, cream cheese and mozzarella combine to create a rich, creamy texture that envelops the chicken and spinach. Cream cheese offers a smooth, tangy base, while mozzarella provides a mild, melty quality that brings everything together in a luscious, cheesy finish.

Step-by-Step Instructions for Creamy Chicken and Spinach Casserole

Preheat the Oven

Start by preheating your oven to 400°F (200°C). Preheating is essential for even cooking, allowing the casserole to bake thoroughly from the start. A hot oven helps the chicken cook faster and ensures that the cheese melts evenly, creating a creamy, golden layer on top. While the oven heats, you can prepare the rest of the ingredients, which saves time and helps everything come together seamlessly. Lightly grease a 9×13-inch baking dish with butter or cooking spray.

Prepare the Chicken 

To ensure even cooking, slice each boneless, skinless chicken breast in half horizontally, creating four thin cutlets. This not only reduces cooking time but also helps the chicken absorb flavors more effectively. For the best results, use a rolling pin or meat mallet to gently pound the thicker ends of each cutlet until they are of uniform thickness. This step prevents any unevenly cooked or tough sections in the casserole, resulting in tender, juicy chicken. Uniform thickness also allows each piece to be cooked to the perfect internal temperature at the same time.

Marinate the Chicken 

Marinating the chicken infuses it with flavor, adding depth to every bite. In a large bowl, combine 1 tablespoon of olive oil, minced garlic, Italian seasoning, salt, and black pepper. Olive oil acts as a base for the marinade, coating the chicken and preventing it from drying out. The garlic adds a savory aroma, while Italian seasoning blends herbs like basil, oregano, and thyme, enhancing the natural flavors of the chicken and complementing the creamy spinach mixture. Salt and pepper balance the flavors, highlighting each component without overwhelming them.

Add the chicken cutlets to the marinade, tossing them to ensure an even coat. For best results, cover the bowl and refrigerate the marinated chicken for 15 to 30 minutes, allowing time for the flavors to soak in. If you’re short on time, even a quick 10-minute marinade can still enhance the dish.

Cook the Spinach 

In a large skillet, heat the remaining tablespoon of olive oil over medium heat. Add the fresh spinach and cook, stirring frequently, until it wilts, which should take about 2 to 3 minutes. Sautéing the spinach this way helps release excess moisture, preventing a watery casserole. Once wilted, transfer the spinach to a paper towel and gently press to remove additional moisture. This step is essential to achieving a creamy consistency in the final dish, as it keeps the casserole thick and prevents it from becoming too runny during baking.

Prepare the Creamy Spinach Mixture 

In a medium bowl, beat the softened cream cheese until smooth. This creates a creamy base that binds the spinach and cheese together, resulting in a velvety texture throughout the casserole. Add the wilted spinach, half a cup of shredded mozzarella, and the Parmesan cheese (if using). The mozzarella adds a mild, melty element, while the Parmesan offers a sharper, savory note. Stir until fully combined, ensuring the spinach is evenly distributed in the mixture. This will help create a uniform layer when it’s spread over the chicken, so each bite has the perfect balance of spinach and cheese.

Assemble the Casserole 

Remove the chicken from the marinade, letting any excess drip off. For an added boost of flavor, you can sear each piece in a skillet over medium heat for 1 to 2 minutes per side; however, this step is optional. Arrange the chicken cutlets in a single layer in the greased baking dish, ensuring even spacing for consistent cooking. Spread the creamy spinach mixture over the chicken, covering each piece to ensure every bite is rich and creamy. Distribute it evenly to avoid any gaps. Finally, sprinkle the remaining half cup of mozzarella cheese over the top. This final layer will melt beautifully in the oven, creating a golden, bubbly crust that adds to the casserole’s creamy texture and visual appeal.

Bake 

Place the assembled casserole in the preheated oven and bake for 20 to 30 minutes, or until the chicken is fully cooked, reaching an internal temperature of 165°F. Baking at 400°F allows the cheese to melt and brown slightly, creating a creamy and lightly crisp top layer. Visual cues like bubbling cheese and a lightly golden crust indicate doneness. Using a meat thermometer ensures the chicken is cooked through without overbaking, which keeps it tender and juicy. The result is a warm, cheesy casserole with perfectly cooked chicken beneath a rich, creamy topping.

Serve and Enjoy 

Once baked, let the casserole rest for about 5 minutes before serving. This resting time allows the cheese and creamy spinach mixture to settle, making it easier to slice and serve without losing structure. For a complete meal, serve the casserole warm with a side of crusty bread, which pairs perfectly with the rich, creamy flavors, or a light salad for a refreshing contrast. Each bite of this creamy chicken and spinach casserole is a delicious balance of tender chicken, savory cheese, and vibrant spinach—a satisfying dish that’s sure to please any crowd.

Tips and Tricks for the Best Creamy Chicken and Spinach Casserole

To achieve the best possible results with this casserole, follow these tips and tricks for tender chicken, delicious flavors, and easy meal prep.

1. Avoid Dry Chicken
   Pounding the chicken cutlets to an even thickness ensures that they cook uniformly, preventing some parts from drying out while others finish cooking. Additionally, marinating the chicken in a mix of olive oil, garlic, and Italian seasoning helps it retain moisture and absorb flavors, making each bite tender and juicy. Even a short marination time of 15 to 30 minutes can make a noticeable difference in flavor and texture.
2. Add-Ins and Substitutes
   This casserole is highly customizable. To boost the flavor profile and add more veggies, consider mixing in sautéed mushrooms, which add a hearty, earthy taste, or diced bell peppers, which provide a mild sweetness and extra color. If you want more greens, add some kale or arugula to the spinach mixture. For those who prefer a spicier dish, sprinkle in red pepper flakes or add a bit of chopped jalapeño to the creamy mixture.
3. Storage and Reheating
   Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover the casserole with foil and warm it in a 350°F oven for 10 to 15 minutes, or until heated through. This helps retain moisture and prevents the casserole from drying out. Alternatively, individual portions can be reheated in the microwave in 30-second intervals.
4. Make It Ahead for Easy Meal Prep
   This casserole can easily be prepared in advance. Follow the steps up to assembling the casserole, then cover the dish tightly with foil and refrigerate for up to 24 hours. When ready to bake, simply remove it from the fridge, uncover, and bake as directed. This make-ahead option is perfect for busy nights when you want a warm, home-cooked meal with minimal effort.

This creamy chicken and spinach casserole is a rich, filling dish that provides a good balance of protein, healthy fats, and essential nutrients. The calorie content mainly comes from the chicken and cheeses, which offer a substantial amount of protein for muscle maintenance and repair. Each serving is likely to provide around 300-400 calories, depending on portion size, with approximately 20-25 grams of protein, primarily from the chicken and mozzarella cheese. Healthy fats from the olive oil and cheese contribute to satiety, helping you feel fuller for longer.

Spinach, a superfood, is packed with vitamins A, C, and K, as well as iron, magnesium, and fiber. This boosts the casserole’s nutrient profile, supporting eye health, immune function, and heart health. Chicken is lean and high in protein, ideal for a balanced diet, while the cheeses add calcium and essential fats.

For a lighter, lower-carb version, consider using reduced-fat cream cheese and mozzarella. You can also increase the spinach or add other low-carb vegetables like mushrooms or bell peppers to reduce calorie density while adding volume and nutrients. By making these adjustments, you can enjoy a lighter version of this delicious casserole without compromising on flavor or satisfaction.

This creamy chicken and spinach casserole is versatile, with several options for customizing it to fit different dietary needs and flavor preferences.

1. Low-Carb/Keto Version
   To make this casserole low-carb or keto-friendly, it’s already quite close to fitting those requirements! Simply ensure you use full-fat cream cheese and mozzarella for optimal fat content. To reduce carbs further, you can double the amount of spinach or add other low-carb vegetables like bell peppers, mushrooms, or zucchini. These options add volume and nutrients without adding significant carbs. Avoid using any breadcrumbs or carb-heavy side dishes, and serve it with a side of leafy greens or roasted vegetables instead.
2. Vegetarian Option
   For a vegetarian twist, replace the chicken with hearty vegetables or tofu. Sliced portobello mushrooms, cauliflower florets, or extra spinach can add texture and flavor. For protein, add cubed or sliced tofu, marinated in olive oil, garlic, and Italian seasoning to absorb flavor. These substitutions maintain the casserole’s creamy, savory profile while making it meat-free.
3. Spicy Twist
   If you enjoy some heat, add red pepper flakes to the spinach mixture, or layer in diced jalapeños for a spicier bite. You can also sprinkle a spicy seasoning blend, like Cajun seasoning or smoked paprika, over the chicken before baking. This adds a new flavor dimension, creating a warm, spicy edge that balances well with the creamy cheese and spinach.

Description

This Chicken Bacon Ranch Stromboli is a delicious twist on classic flavors, featuring savory rotisserie chicken, smoky turkey bacon, and creamy ranch dressing, all wrapped up in golden pizza dough. Perfect as a game-day snack, dinner, or anytime craving!

---

Ingredients

Scale 1x2x3x

• 1 (8-ounce) can thin crust refrigerated pizza dough
• 1/2 cup prepared ranch dressing, plus more for dipping
• 2 cups shredded rotisserie chicken
• 1/2 cup chopped, cooked turkey bacon
• 2 cups shredded mozzarella cheese

---

Instructions

1️⃣ Preheat the Oven:

Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup and to prevent sticking.

2️⃣ Prepare the Dough:

Remove the pizza dough from its packaging. On the prepared baking sheet with parchment paper, gently stretch the dough until it’s thin and even, being careful not to tear it. This will be the base of your stromboli.

3️⃣ Add the Filling:

Spread a thin layer of ranch dressing over the dough, leaving about a 1-inch border around the edges to help with sealing.

Evenly distribute the shredded rotisserie chicken over the ranch dressing, followed by the chopped turkey bacon, and top it all with shredded mozzarella cheese.

4️⃣ Roll the Stromboli:

Starting from one long side, carefully roll the dough toward the opposite side, using the parchment paper to keep the roll tight.

Place the stromboli seam-side down on the baking sheet to keep it secure during baking. Tuck the ends under to seal in the filling.

5️⃣ Prepare for Baking:

Use a sharp knife to cut several diagonal slits along the top of the stromboli. These slits allow steam to escape during baking, ensuring a golden and crisp crust.

6️⃣ Bake:

Place the stromboli in the preheated oven and bake for 15-25 minutes, or until the crust is a deep golden brown.

7️⃣ Serve:

Let the stromboli cool for a few minutes before slicing. Serve warm with extra ranch dressing for dipping.

Notes

• Bacon Substitution: Turkey bacon offers a lighter alternative to regular bacon, with less fat but still a smoky flavor.
• Alternative Fillings: You can add other fillings like sautéed bell peppers or spinach for extra flavor and texture.
• Customizable Dips: Ranch is classic, but marinara or even a light garlic aioli can add a unique twist!
