How To Make the Chicken and Spinach Casserole with Cream Cheese
Step 1: Sear the Chicken
Heat olive oil in a skillet over medium heat. Add the chicken cubes and season with garlic powder, onion powder, salt, and pepper. Sear until golden and cooked through, about 5–6 minutes. Remove and set aside.

Step 2: Sauté the Aromatics
In the same pan, add butter, diced onion, and garlic. Sauté until fragrant and translucent.

Step 3: Wilt the Spinach
Add the spinach and cook until wilted. This will take just 1–2 minutes.

Step 4: Make It Creamy
Lower the heat and stir in the cream cheese, heavy cream, and parmesan. Stir until smooth and creamy. Add chili flakes if you like a little heat.

Step 5: Assemble the Casserole
Add the cooked chicken back to the skillet and stir to coat everything evenly. Transfer to a greased baking dish.

Step 6: Bake to Perfection
Bake at 375°F (190°C) for 15–20 minutes or until bubbly and golden on top.

How to Serve and Store Your Chicken and Spinach Casserole
Serve it hot with garlic bread, steamed rice, or mashed potatoes. Store leftovers in the fridge for up to 3 days. Reheat in the oven or microwave.
