Chicken Florentine Pasta Recipe: Spinach-Rich Cream Sauce With Tender Chicken

This dish combines tender chicken, fresh spinach, and a velvety cream sauce for a main course that feels special without complicated techniques. The key lies in cooking the chicken just until it reaches 165°F, ensuring it stays juicy and tender throughout the process.

The cream sauce comes together quickly with simple ingredients, creating a rich base that perfectly coats the pasta. Fresh spinach wilts directly into the sauce, adding vibrant color and a touch of earthiness that balances the dish beautifully.

Each bite delivers a harmony of textures and flavors—creamy sauce, tender chicken, and al dente pasta. The spinach adds a fresh, slightly bitter note that keeps the dish from feeling too heavy.

Ready in under an hour, this meal proves that restaurant-quality results are achievable at home with straightforward steps.

Ingredients for Chicken Florentine Pasta

Simple, high-quality ingredients create this restaurant-worthy dish with ease.

The chicken is the star here—opt for boneless, skinless breasts for even cooking and that promised tenderness. Costco or Whole Foods have reliable quality. For the pasta, fettuccine or linguine holds the creamy sauce best. Spinach should be fresh (baby spinach is easiest) and vibrant green, not wilted. The Parmesan? Freshly grated from a wedge—pre-shredded clumps and lacks flavor.

No white wine? Substitute with additional chicken broth plus a squeeze of lemon for acidity. Fresh spinach can be swapped with frozen—just thaw and drain well to avoid a watery sauce. Heavy cream is non-negotiable for the velvety texture, but half-and-half works in a pinch (texture will be lighter). For the nutmeg, a pinch of mace is an acceptable substitute.

This dish reheats well—store in an airtight container for up to 3 days in the fridge. The sauce may thicken slightly; thin with a splash of broth when reheating. Freezes beautifully for up to 2 months (the spinach may darken slightly but flavor holds).

Step-by-Step Instructions for Chicken Florentine Pasta

Here’s the method. Straightforward, tested, works every time.

Step 1: Cook Pasta and Prep Chicken

Bring a large pot of salted water to a boil and add the 12 oz Fettuccine Pasta. Cook according to package instructions until al dente, about 8-10 minutes. Reserve 1 cup of pasta water before draining.

Meanwhile, season the 1.5 lb Chicken Breast with 1 tsp Salt and 0.5 tsp Black Pepper. Cut into 1-inch thick strips. Heat 2 tbsp of the 0.5 cup Unsalted Butter in a large skillet over medium-high heat until melted.

Add the chicken and cook for 5-6 minutes until golden brown and cooked through. Transfer to a plate and cover to keep warm.

Step 2: Build the Cream Sauce Base

In the same skillet, reduce heat to medium and add the remaining 0.5 cup Unsalted Butter. Once melted, stir in the 2 tbsp All-Purpose Flour to create a roux. Cook for 1-2 minutes until light golden and bubbly.

Add the finely diced 1 whole Shallot and cook for 2 minutes until soft. Stir in the minced 4 cloves Garlic Cloves and cook for 30 seconds until fragrant. Deglaze with 0.5 cup Dry White Wine, scraping up any browned bits.

Simmer for 2-3 minutes until the liquid reduces by half. This builds the flavor foundation for your sauce.

Step 3: Finish Sauce with Cream and Spinach

Pour in the 1.5 cups Heavy Cream and 0.5 cup Chicken Broth. Stir in 0.25 tsp Nutmeg, then bring to a gentle simmer. Let cook for 3-4 minutes until slightly thickened.

Add the 8 oz Fresh Spinach in batches, stirring until each addition wilts. This should take about 2 minutes. The spinach should be bright green and tender.

Stir in 0.75 cup Parmesan Cheese until fully melted and smooth. If the sauce is too thick, add reserved pasta water 1 tbsp at a time to reach your desired consistency.

Step 4: Combine and Serve

Return the cooked chicken to the skillet with the sauce. Add the drained pasta and toss everything together for 1-2 minutes over low heat to coat evenly. The pasta should be glossy and well-coated.

Taste and adjust seasoning if needed. Serve immediately, garnished with extra grated Parmesan if desired. Each serving should have tender chicken, creamy sauce, and vibrant spinach throughout.

Common Mistakes When Making This Recipe

Overcooked Chicken

Chicken dries out fast if cooked too long. Use a meat thermometer to pull it at exactly 165°F internal temperature. I check the thickest piece to be sure. Overcooking turns your tender chicken into rubbery disappointment. 🌡️

Lumpy Sauce

Your roux needs to cook for 1-2 minutes until golden before adding liquids. Whisk constantly when adding wine and cream to prevent clumping. If lumps form, immediately whisk vigorously or use an immersion blender to smooth it out.

Watery Spinach

Fresh spinach releases moisture as it wilts. Add it in batches and cook until each addition reduces before adding more. If using frozen, thaw and squeeze out all water first. This prevents a thin, watery sauce that won’t cling to pasta.

Underseasoned Dish

Taste as you go, especially after adding Parmesan which can be salty. The sauce often needs an extra pinch of salt and black pepper at the end. Remember, the pasta water you reserved can also carry seasoning into the final dish.

Mushy Pasta

Cook pasta 1-2 minutes less than package instructions since it finishes in the sauce. Reserve that starchy pasta water early—it’s your secret weapon for adjusting sauce consistency and helping it adhere to the noodles. 💡

Curdy Cream Sauce

High heat can cause cream to separate. Keep your sauce at a gentle simmer, never a boil. If you see curdling, immediately reduce heat and whisk in 1-2 tbsp cold heavy cream to bring it back together smoothly.
