How to Make Lemon Garlic Chicken with Parmesan Herb Sauce Recipe
Step 1: Preheat and Prepare the Marinade
Begin by setting your oven to 400 degrees Fahrenheit to get it ready for roasting. Combine olive oil, minced garlic, lemon juice, lemon zest, Dijon mustard, salt, pepper, basil, oregano, onion powder, paprika, cumin, thyme, and sugar in a resealable bag. This simple yet flavorful marinade is going to infuse the chicken with incredible bright, savory notes that dazzle the taste buds.
Step 2: Marinate the Chicken
Drop your chicken thighs into the bag with the marinade and make sure every piece is thoroughly coated. Let it rest for 20 minutes. This brief marinade time is enough to ensure the chicken remains juicy and packed with a vibrant taste, without needing to wait hours.
Step 3: Prepare the Potatoes
Line a large sheet pan with foil for easy cleanup. Toss the quartered baby Dutch potatoes with the marinade that’s been reserved from the bag, sprinkling a bit more salt over them. Pop the potatoes in the oven, and bake for 15 minutes until they start to soften and develop a golden crust. This step allows the potatoes to get a head start on cooking so everything finishes perfectly together.
Step 4: Add Chicken and Broccoli
After the potatoes have baked, add the broccoli florets and marinated chicken thighs to the same sheet pan. This one-pan approach maximizes flavor mingling and makes cleanup a breeze. Return the pan to the oven and roast everything for an additional 17 to 22 minutes, or until the chicken reaches a safe internal temperature and the broccoli is tender yet still vibrant.
Step 5: Make the Parmesan Herb Sauce
While the chicken and vegetables roast, prepare your luscious sauce. Combine the Greek yogurt or sour cream with finely grated Parmesan, chopped parsley, lemon juice, and optional chives and dill. Season with salt, cumin, and pepper, blending everything until smooth and creamy. This sauce is the star accompaniment, bringing a tangy, herbaceous creaminess that perfectly complements the warm, roasted components.
How to Serve Lemon Garlic Chicken with Parmesan Herb Sauce Recipe

Garnishes
Fresh garnish can elevate the dish instantly. Sprinkle chopped parsley or dill over the finished meal for a vibrant herbal touch. A final zesting of lemon will add an aromatic sparkle that brings the dish alive right at serving.
Side Dishes
This recipe is wonderfully complete on its own, but if you want to pair it with something else, light options like a crisp green salad or a simple quinoa pilaf work beautifully. They keep the meal balanced and add textural contrast without overshadowing the chicken and sauce.
Creative Ways to Present
For a stylish presentation, serve the chicken thighs sliced atop the roasted potatoes and broccoli, drizzling the Parmesan Herb Sauce generously over the top. Alternatively, offer the sauce in a small bowl on the side for dipping, allowing guests to control how much creamy indulgence they prefer.
Make Ahead and Storage
Storing Leftovers
Place any leftover chicken, potatoes, broccoli, and sauce in airtight containers and refrigerate for up to 3 days. This dish retains its flavors beautifully, allowing you to enjoy the magic of this recipe again with minimal effort.
Freezing
If you want to freeze the components separately, the chicken freezes well up to 2 months, and the sauce can be frozen too, though it’s best to thaw and give it a good stir before serving. Potatoes and broccoli might lose some texture after freezing, so consider eating those fresh.
Reheating
Reheat the chicken and vegetables gently in the oven at 350 degrees Fahrenheit until warmed through, ensuring the chicken stays moist. Warm the sauce separately in the microwave or on the stovetop, stirring occasionally to restore its creamy consistency.
FAQs
Can I use chicken breasts instead of thighs?
Absolutely! Chicken breasts work well if you prefer leaner meat—just be mindful they may cook faster and can dry out if overcooked. Keep a close eye during roasting to maintain juiciness.
Is Greek yogurt necessary for the sauce?
Greek yogurt gives the sauce a thick, creamy texture and tanginess that balances the lemon and Parmesan beautifully. Sour cream is a great alternative if you prefer a milder flavor.
Can I make this recipe gluten-free?
Yes! All the ingredients in this Lemon Garlic Chicken with Parmesan Herb Sauce Recipe are naturally gluten-free, but double-check your Dijon mustard and spices to ensure they do not contain any gluten.
What’s the best way to zest a lemon?
Use a microplane or fine grater to zest only the yellow part of the lemon peel, avoiding the bitter white pith underneath. Fresh zest adds vibrant aromas that can’t be beaten.
Can I add other vegetables?
Definitely! Feel free to toss in sliced bell peppers, asparagus, or green beans alongside the broccoli for more variety and color to your dish.
Final Thoughts
This Lemon Garlic Chicken with Parmesan Herb Sauce Recipe is truly a joy to make and share.
