Prep the chicken: Pat the chicken cutlets dry. Season both sides with salt, pepper, Italian seasoning, and paprika.
Sear the chicken: Heat olive oil in a large skillet over medium-high heat.
Add chicken in a single layer and sear 3–4 minutes per side until golden and just cooked through. Transfer to a plate and tent with foil.
Sauté aromatics: Reduce heat to medium. Add butter to the skillet.
Stir in shallot and cook 1–2 minutes until softened. Add garlic and cook 30 seconds until fragrant.
Build the sauce: Stir in sun-dried tomatoes. Add chicken broth and scrape up any browned bits.
Simmer 2 minutes to reduce slightly.
Add cream and cheese: Pour in the heavy cream and bring to a gentle simmer. Stir in Parmesan until melted and smooth. If you like heat, add a pinch of red pepper flakes.
Wilt the spinach: Add spinach and cook 1–2 minutes until just wilted.
Taste and adjust salt and pepper as needed.
Finish the chicken: Return chicken and any juices to the skillet. Simmer 2–3 minutes to warm through and thicken the sauce to a spoon-coating consistency. For brightness, add lemon zest or a squeeze of lemon.
Garnish and serve: Sprinkle with chopped basil or parsley and extra Parmesan.
Serve over cauliflower rice, sautéed zucchini, or roasted broccoli for a complete keto meal.
