Ingredients
Method
- Prep the chicken: Pat the chicken dry. Season both sides with salt, pepper, paprika, and half the Italian seasoning.
- Sear the chicken: Heat the olive oil in a large skillet over medium-high heat. Add chicken and cook 3–5 minutes per side until lightly browned and almost cooked through. Transfer to a plate.
- Sauté the aromatics: Reduce heat to medium. In the same pan, add the onion with a pinch of salt. Cook 2–3 minutes until softened. Add garlic and cook 30 seconds, stirring.
- Build the sauce base: Pour in the chicken broth and milk. Stir in the remaining Italian seasoning and red pepper flakes. Bring to a gentle simmer.
- Thicken (optional): If you want a thicker sauce, whisk the cornstarch with 1 tablespoon cold water, then stir it into the pan. Simmer 1 minute until slightly thickened.
- Add spinach: Stir in the spinach a handful at a time until wilted. If using frozen, make sure it’s well-drained and squeeze out excess moisture before adding.
- Finish the creamy element: Reduce heat to low. In a small bowl, whisk the Greek yogurt with a few spoonfuls of hot sauce from the pan to temper it. Then stir the yogurt back into the skillet. Add Parmesan and lemon zest. Stir until smooth and creamy. Do not boil.
- Return the chicken: Nestle the chicken back into the sauce. Simmer gently 2–4 minutes until the chicken reaches 165°F in the thickest part and the sauce is silky.
- Brighten and adjust: Add lemon juice, taste, and adjust salt and pepper. If the sauce is too thick, splash in a bit more broth or milk. If too thin, simmer another minute.
- Serve: Garnish with herbs and extra Parmesan if you like. Serve with cauliflower rice, zucchini noodles, or a small portion of whole-grain pasta or brown rice.

Keeping It Fresh
Store leftovers in an airtight container in the fridge for up to 3 days.
The sauce will stay creamy if you reheat gently. Use low heat on the stovetop or 50% power in the microwave, stirring halfway.
Freezing tips: Greek yogurt sauces can separate when frozen. If you plan to freeze, cook the chicken and spinach sauce base without the yogurt.
Freeze up to 2 months. Thaw overnight, reheat gently, then stir in the yogurt and Parmesan before serving.
Leftover chicken slices are great over salads, tucked in a whole-grain wrap, or spooned on top of roasted veggies for a quick lunch.
Why This Is Good for You
- High protein, low calorie: Chicken breast provides lean protein that supports muscle and keeps you full.
- Heart-smart fats: A small amount of olive oil adds healthy monounsaturated fat without piling on calories.
- Greens galore: Spinach brings iron, folate, vitamin K, and antioxidants for everyday health.
- Lighter creaminess: Greek yogurt and milk create a creamy feel with fewer calories and more protein than heavy cream.
- Sodium-aware: Using low-sodium broth keeps the salt in check while preserving flavor.
Common Mistakes to Avoid
- Boiling the yogurt: High heat can cause the sauce to curdle. Keep it at a gentle simmer and temper the yogurt first.
- Skipping the drain on frozen spinach: Extra water will thin the sauce.
Squeeze it dry before adding.
- Overcooking the chicken: Dry chicken ruins the dish. Sear, then finish gently in the sauce until 165°F.
- Not seasoning in layers: Season the chicken, then adjust the sauce at the end. Layered seasoning equals balanced flavor.
- Too much Parmesan at once: Adding heaps can make the sauce gritty or too salty.
Start modest and add to taste.
Alternatives
- Dairy-free: Use unsweetened almond or oat milk and swap Greek yogurt for a plain dairy-free yogurt. Choose a vegan Parmesan-style topping.
- Extra veggies: Add sliced mushrooms, halved cherry tomatoes, or zucchini ribbons after the onions for more volume and nutrients.
- Different protein: Try turkey cutlets or boneless, skinless chicken thighs. For pescatarian, use seared shrimp and reduce simmer time.
- Herb swap: Use dried basil and oregano, or add fresh dill or tarragon for a different flavor profile.
- Spice variation: Smoked paprika and a pinch of cayenne add warmth; a dash of nutmeg emphasizes the creamy spinach notes.
- Gluten-free: This dish is naturally gluten-free as written.
Serve with gluten-free pasta, quinoa, or cauliflower mash.
FAQ
Can I use half-and-half instead of milk?
Yes, half-and-half will make the sauce richer. If you use it, you can skip the cornstarch. Keep the heat gentle to prevent curdling once you add the yogurt.
How do I make the sauce thicker without cornstarch?
Simmer the sauce a bit longer before adding yogurt, or add an extra tablespoon of Parmesan.
You can also mash a few cooked cauliflower florets into the sauce for natural thickness.
Can I use frozen chicken?
Thaw the chicken fully in the refrigerator before cooking. Cooking from frozen will brown unevenly and can dry out the exterior before the inside cooks through.
What can I serve with this to keep it low calorie?
Try cauliflower rice, steamed green beans, a simple side salad, or zucchini noodles. A small serving of brown rice or farro also works if you want more carbs.
How do I prevent the sauce from curdling?
Temper the yogurt with a little hot sauce from the pan, reduce the heat to low, and avoid boiling after the yogurt goes in.
Stir gently and add lemon juice at the end.
Is Greek yogurt essential?
It’s the main source of creaminess with fewer calories, but you can substitute low-fat plain yogurt. If using regular yogurt, drain it briefly in a sieve to thicken it.
