1 teaspoon kosher salt
1/2 teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon Italian seasoning or dried oregano and basil mix

For searing

2 tablespoons olive oil or avocado oil
1 tablespoon unsalted butter (adds flavor and browning)

Creamy spinach Parmesan sauce

3 cloves garlic, minced (jarred minced garlic works in a pinch)
1 cup low sodium chicken broth (Better Than Bouillon gives strong flavor)
1 cup heavy cream or half and half for a lighter version
3/4 cup finely grated Parmesan cheese (use real Parmigiano or a good domestic wedge, not the green can)
1 teaspoon Dijon mustard (optional, but it adds depth and slight tang)
1/4 teaspoon red pepper flakes (optional for gentle heat)
3 cups fresh baby spinach, loosely packed
1 tablespoon fresh lemon juice
Salt and pepper to taste

Optional add ins

1/2 cup sliced sun dried tomatoes in oil, drained
1/2 cup sliced mushrooms, sautéed before adding cream

Equipment

Large heavy skillet, 10 to 12 inch (cast iron or stainless works best)
Tongs for turning chicken
Wooden spoon or silicone spatula
Cutting board and sharp knife
Small whisk for the sauce

Quick Tips & substitutions

Pound thicker chicken breasts to even thickness so they cook evenly and stay juicy.
Use half and half instead of heavy cream if you want a lighter sauce, and simmer a bit longer to thicken.
Swap baby spinach with chopped kale; cook kale a few minutes longer until tender.
Use grated Pecorino Romano in place of Parmesan for a sharper, saltier flavor; reduce added salt slightly.
Stir in a spoonful of cream cheese if you want an extra thick, ultra creamy sauce.
Use frozen spinach in a pinch; thaw it and squeeze it very dry in a towel before adding.
Replace chicken broth with vegetable broth if you only have that on hand.
Slice leftover chicken and sauce over pasta or rice the next day to stretch the meal.

How to Make Creamy Chicken Breast in Spinach Parmesan Sauce Recipe

Season and prep the chicken

Pat the chicken breasts dry with paper towels, then slice them horizontally to make 4 cutlets. Mix salt, pepper, garlic powder, onion powder, and Italian seasoning in a small bowl. Sprinkle the seasoning mix over both sides of the chicken and press it in so it sticks.

Sear the chicken

Heat olive oil and butter in the skillet over medium high heat until the butter foams. Lay the chicken cutlets in the pan without crowding and let them sear until golden on the first side, about 4 to 5 minutes. Flip and cook the second side until the chicken reaches 165°F in the thickest part, about 3 to 4 more minutes, then transfer to a plate and tent loosely with foil.

Build the flavor base

Lower the heat to medium and add the minced garlic to the same skillet. Stir and cook the garlic for about 30 seconds until fragrant, and scrape up the browned bits from the bottom with your spoon. Pour in the chicken broth and whisk in the Dijon mustard if you use it, then let the mixture simmer for 2 to 3 minutes to reduce slightly.

Make the creamy Parmesan sauce

Pour in the heavy cream and stir until the broth and cream blend. Bring the mixture to a gentle simmer, not a hard boil, and cook for 3 to 5 minutes until it thickens enough to coat the back of a spoon. Sprinkle in the grated Parmesan a little at a time while you whisk, so it melts smoothly and does not clump.

Taste the sauce and add salt, pepper, and red pepper flakes to your liking. If the sauce seems too thick, splash in a bit more broth or cream. If it seems thin, keep it at a gentle simmer and stir until it thickens.

Add spinach and extras

Stir in the baby spinach and let it wilt into the sauce, about 1 to 2 minutes. Add sun dried tomatoes or cooked mushrooms if you use them and stir to combine. Squeeze in the lemon juice and taste again, since the acid brightens the rich sauce.

Finish the chicken in the sauce

Nestle the cooked chicken cutlets back into the skillet, along with any juices that collected on the plate. Spoon the spinach Parmesan sauce over the chicken and let everything simmer together for 2 to 3 minutes so the flavors blend. Turn off the heat and let the skillet sit for a minute so the sauce thickens slightly around the chicken.

Slice the chicken if you like, then serve it hot with extra sauce spooned over the top. Garnish with a little extra grated Parmesan or chopped parsley if you want a pop of color. Take a second to admire the skillet, then dig in before the sauce cools.

Recipe Variations

Gluten free: Use gluten free chicken broth and serve over gluten free pasta, rice, or mashed potatoes.
Lower carb: Serve over zucchini noodles, spaghetti squash, or cauliflower mash instead of pasta or rice.
Extra veggie: Add steamed broccoli florets, peas, or sautéed bell peppers to the sauce.
Spicy version: Double the red pepper flakes and add a pinch of smoked paprika.
Lighter dairy: Use half and half and reduce Parmesan to 1/2 cup, then thicken the sauce a bit longer.
No cream option: Use evaporated milk instead of cream for a lighter but still rich sauce.

Ways to Serve Creamy Chicken Breast in Spinach Parmesan Sauce Recipe

Spoon over al dente pasta like fettuccine, penne, or rotini.
Serve with fluffy white rice, brown rice, or quinoa to soak up the sauce.
Pair with mashed potatoes or roasted baby potatoes.
Keep it light with a side of steamed green beans or roasted asparagus.
Serve with warm crusty bread or garlic bread to swipe through the sauce.

Storage Success

Let the chicken and sauce cool to room temperature, then store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove over low heat and add a splash of broth or cream to loosen the sauce. Stir while it warms so the sauce stays smooth and the chicken heats evenly. Avoid boiling the sauce during reheating, since high heat can cause the dairy to separate.
