Step 1: Prepare the Chicken
Pat the chicken breasts dry with paper towels and season both sides with salt, pepper, Italian seasoning, and smoked paprika.
Heat olive oil in a large skillet over medium-high heat.
Add the chicken and sear for 5-6 minutes per side, until golden brown and cooked through. (The internal temperature should reach 165°F.)
Remove the chicken from the skillet and set it aside on a plate.
Step 2: Make the Creamy Tuscan Sauce
In the same skillet, reduce heat to medium and add butter.
Sauté the minced garlic for 30 seconds until fragrant.
Add the sun-dried tomatoes and cook for another 1-2 minutes, releasing their flavor.
Pour in the chicken broth and scrape up any browned bits from the pan (this adds extra flavor!).
Stir in the heavy cream and Parmesan cheese, whisking to create a smooth, creamy sauce.
Add the spinach and let it wilt into the sauce, stirring occasionally.
Sprinkle in red pepper flakes (if using) and adjust seasoning with salt and black pepper.
Step 3: Bring It All Together
Return the seared chicken to the skillet, nestling it into the sauce.
Let it simmer for 3-4 minutes, allowing the chicken to soak up the creamy goodness.
Garnish with fresh basil or parsley before serving.
