Creamy Spinach Parmesan Baked Chicken

This recipe serves about 4 people.

Ingredients

For the Chicken:

4 boneless, skinless chicken breasts (about 1.5 lbs / 680g total)
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon garlic powder
½ teaspoon paprika (sweet or smoked)
2 tablespoons olive oil
2 tablespoons butter

For the Creamy Spinach Parmesan Sauce:

1 small onion, finely chopped
4 cloves garlic, minced
1 tablespoon all-purpose flour (optional, for slight thickening)
1 cup (240ml) chicken broth
1 cup (240ml) heavy cream (or half-and-half for a lighter version)
4 cups (120g) fresh spinach (about 4 large handfuls)
1 cup (100g) grated Parmesan cheese
¼ teaspoon nutmeg (optional, but classic with spinach)
Salt and pepper, to taste

For the Topping:

½ cup (50g) shredded mozzarella cheese
2 tablespoons fresh parsley, chopped (for garnish)

Instructions

Step 1: Prep the Chicken

Preheat your oven to 375°F (190°C) .
Pat the chicken breasts dry with paper towels. This helps them sear, not steam.
Season both sides generously with salt, pepper, garlic powder, and paprika.

Step 2: Sear the Chicken

In a large oven-safe skillet (cast iron or stainless steel is perfect), heat the olive oil and butter over medium-high heat.
Once the butter is sizzling, place the chicken breasts in the skillet. Sear for 4-5 minutes per side, until golden brown. The chicken does not need to be cooked through at this point.
Remove the chicken from the skillet and set it aside on a plate. It’s okay if it’s a little pink inside—it will finish cooking in the oven.

Step 3: Make the Sauce

Reduce the heat to medium. In the same skillet, add the chopped onion. Sauté for 3-4 minutes until softened.
Add the minced garlic and cook for 1 minute more until fragrant.
Optional: Sprinkle the flour over the onions and garlic. Stir and cook for 1 minute to remove the raw flour taste. This will help thicken the sauce slightly.
Slowly pour in the chicken broth, scraping the bottom of the skillet with a wooden spoon to deglaze and lift up all those flavorful browned bits (fond).
Pour in the heavy cream and bring to a gentle simmer.
Add the fresh spinach in handfuls, stirring constantly. It will wilt down quickly. Keep adding until all the spinach is incorporated.
Stir in the grated Parmesan cheese and nutmeg (if using). Stir until the cheese is melted and the sauce is smooth. Taste and adjust seasoning with salt and pepper.

Step 4: Return Chicken to Skillet

Nestle the seared chicken breasts back into the skillet, placing them in the creamy spinach sauce.
Spoon a little of the sauce over the tops of the chicken.

Step 5: Top and Bake

Sprinkle the shredded mozzarella cheese over the chicken and sauce.
Transfer the skillet to the preheated oven.
Bake uncovered for 20-25 minutes, or until the chicken is cooked through (internal temperature reaches 165°F / 74°C) and the sauce is bubbly and golden.

Step 6: Rest and Serve

Carefully remove the skillet from the oven (it will be very hot!). Let it rest for 5-10 minutes. This allows the juices in the chicken to redistribute.
Garnish with fresh parsley.
Serve hot with crusty bread, pasta, rice, or mashed potatoes to soak up all that creamy sauce.

Why This Recipe Works

One Skillet Wonder: From stovetop to oven, everything cooks in one pan, which means deep flavor from the seared bits and minimal cleanup.
Luxurious Sauce: The combination of heavy cream, Parmesan, and spinach creates a rich, velvety sauce that perfectly coats the chicken.
Juicy Chicken: Searing first locks in flavor, and finishing in the oven ensures the chicken stays moist and tender.

Tips for Success

Pound the Chicken: If your chicken breasts are very thick, place them between plastic wrap and pound them to an even ½-inch thickness. This ensures they cook evenly and quickly.
Use Fresh Spinach: Fresh spinach wilts down beautifully and has a better texture than frozen for this dish. If you only have frozen, thaw it completely and squeeze it dry before adding.
Don’t Overbake: Use a meat thermometer to check for doneness. Overcooked chicken breasts become dry and stringy. 165°F is the target.
Oven-Safe Skillet: Make sure your skillet is oven-safe. If it’s not (e.g., a plastic handle), transfer the sauce to a baking dish, nestle in the chicken, top with cheese, and bake.

Variations

Sun-Dried Tomato & Spinach: Add ⅓ cup chopped sun-dried tomatoes (in oil, drained) to the sauce along with the spinach for a burst of tangy sweetness.
Mushroom Spinach Chicken: Sauté 8 oz of sliced mushrooms with the onions for an earthy depth of flavor.
Spicy Kick: Add a pinch of red pepper flakes to the sauce for some heat.
Lighter Version: Use half-and-half instead of heavy cream and reduce the Parmesan to ½ cup. Omit the mozzarella topping or use part-skim.
