Essential Equipment You’ll Need for This Recipe

1. 9×13 Baking Dish
   Once I started using this baking dish, it became my favorite for casseroles. It ensures even cooking and has enough space for layering all the ingredients perfectly.
2. Skillet
   This is my go-to for cooking the chicken and sautéing the spinach. It distributes heat evenly, making it perfect for pre-cooking ingredients before baking.
3. Mixing Bowl
   A reliable mixing bowl is essential for combining the creamy sauce ingredients smoothly and efficiently.
4. Measuring Cups and Spoons
   Accurate measurements make all the difference in recipes like this. These tools ensure the perfect ratio of creaminess to flavor.
5. Knife and Cutting Board
   A sturdy knife and cutting board are a must for chopping the chicken into bite-sized pieces and prepping the spinach.

Ingredients & Substitutions

For the Casserole

• 4 boneless, skinless chicken breasts (can substitute with chicken thighs for a juicier texture)
• 4 cups fresh spinach (frozen spinach works; thaw and drain well before use)
• 8 oz cream cheese (can substitute with mascarpone or ricotta for a lighter texture)
• 1/2 cup heavy cream (unsweetened almond milk is a lighter alternative but less creamy)
• 1 cup shredded mozzarella cheese (can substitute with cheddar or provolone)
• 1/4 cup grated parmesan cheese (adds depth but can use Asiago cheese instead)
• 2 cloves garlic, minced (substitute with 1/2 tsp garlic powder)
• 1 tbsp olive oil (can replace with avocado oil)
• Salt and pepper to taste

How to Make Keto Chicken Florentine Casserole

Step 1: Preheat the Oven

• Preheat your oven to 375°F (190°C). Grease a 9×13 baking dish with olive oil or cooking spray.

Step 2: Cook the Chicken

• Heat olive oil in a skillet over medium heat. Season the chicken breasts with salt and pepper, then cook for 6-7 minutes per side until fully cooked.
• Let the chicken cool slightly, then dice it into bite-sized pieces.

Step 3: Sauté the Spinach

• In the same skillet, sauté the spinach for 2-3 minutes until wilted. Remove from heat and set aside.

Step 4: Prepare the Creamy Sauce

• In a mixing bowl, combine cream cheese, heavy cream, minced garlic, mozzarella cheese, and parmesan cheese. Mix until smooth.
• Add salt and pepper to taste.

Step 5: Assemble the Casserole

• Layer the diced chicken and sautéed spinach evenly in the greased baking dish.
• Pour the creamy sauce over the top, spreading it evenly to coat everything.

Step 6: Bake

• Bake for 20-25 minutes or until the top is golden and bubbly.

Step 7: Serve

• Let the casserole cool for a few minutes before slicing and serving. Enjoy!

Optional Additions

• Mushrooms: Sautéed mushrooms add earthy flavor.
• Bacon: Crumbled crispy bacon for a smoky, savory kick.
• Herbs: Fresh thyme or basil sprinkled on top before baking enhances flavor.

Serving Ideas

• Cauliflower Rice: Serve over cauliflower rice for a filling low-carb meal.
• Zucchini Noodles: A great base to complement the creamy casserole.
• Side Salad: A light side salad with lemon vinaigrette balances the richness.

Storage Recommendations
