Copycat Longhorn Parmesan Crusted Chicken brings juicy, restaurant-style chicken with a creamy Parmesan crust straight to your dinner table.

If you love ordering Parmesan crusted chicken at a steakhouse, this homemade version will feel like a little victory in your own kitchen. Tender, juicy chicken breasts get a smoky, savory seasoning and a beautiful golden sear.

Then comes the star: a thick Parmesan, provolone, and breadcrumb topping enriched with a touch of mayo and sour cream. It bakes under the broiler just long enough to melt, bubble, and turn irresistibly crisp around the edges.

The result is a cheesy, garlicky crust over perfectly cooked chicken that pairs with everything from mashed potatoes to a simple salad. It’s weeknight friendly, date-night worthy, and fancy enough for guests without being fussy or complicated.

Copycat Longhorn Parmesan Crusted Chicken Ingredients

Boneless skinless chicken breasts – The base of the dish; pounding them slightly helps them cook evenly and stay juicy.
Olive oil – Coats the chicken so the spices stick and promotes a flavorful, golden sear.
Garlic powder – Adds deep, savory flavor that complements the cheesy crust without overpowering it.
Paprika – Gives gentle warmth and a pretty color to the seasoned chicken.
Italian seasoning – Brings in an herby, steakhouse-style flavor blend that works beautifully with Parmesan.
Salt and black pepper – Simple but essential; they balance the richness and bring out every other flavor.
Grated Parmesan cheese – The main flavor in the crust; salty, nutty, and perfect for browning under the broiler.
Shredded provolone or mozzarella – Melts into a gooey layer that helps the crust cling to the chicken.
Panko breadcrumbs – Create that signature crunchy, golden topping while absorbing some of the cheesy richness.
Mayonnaise – Makes the topping creamy and spreadable, with a silky texture when broiled.
Sour cream – Adds tang and keeps the crust moist while it browns.
Fresh parsley – Optional, but adds a pop of color and a fresh, bright finish on top of the rich chicken.

Step-by-Step Copycat Longhorn Parmesan Crusted Chicken

STEP 1: Prepare the chicken breasts
Place the chicken between sheets of parchment or plastic wrap and gently pound the thickest parts so each piece is an even thickness. This helps the chicken cook quickly and prevents dry edges.

STEP 2: Season the chicken
Rub each breast with olive oil on both sides. Sprinkle with garlic powder, paprika, Italian seasoning, salt, and black pepper, pressing the spices in lightly so they adhere to the surface.

STEP 3: Sear until golden
Heat a large skillet or grill pan over medium-high heat. Add the seasoned chicken and cook for about 4–5 minutes per side, until nicely browned and the internal temperature reaches 165°F (74°C). Transfer the chicken to a baking dish.

STEP 4: Mix the Parmesan crust
In a bowl, stir together the mayonnaise, sour cream, grated Parmesan, shredded provolone or mozzarella, and panko breadcrumbs. The mixture should be thick and spreadable, holding together on a spoon.

STEP 5: Top the chicken generously
Spoon the Parmesan mixture onto each chicken breast, spreading it evenly to cover the top. Press it lightly so it forms a uniform layer that won’t slide off under the broiler.

STEP 6: Broil to bubbly perfection
Preheat your oven broiler. Place the baking dish on the middle or upper rack, watching carefully, and broil for 2–3 minutes. The topping should be melted, bubbling, and lightly golden around the edges.

STEP 7: Rest and garnish
Remove from the oven and let the chicken rest for a few minutes so the juices settle. Sprinkle with chopped fresh parsley for a bright, restaurant-style finish before serving.

Recipe Tips

Don’t skip pounding the chicken: A more even thickness means the chicken cooks at the same rate, so you avoid overcooked edges and undercooked centers.
Watch the broiler closely: Every broiler is different; stay nearby and pull the dish as soon as the crust is golden and bubbling.
Season in layers: Taste the topping before spreading it—if it needs a pinch of salt or pepper, add it so the crust is as flavorful as the chicken.

Can I use chicken thighs instead of breasts?

Yes. Boneless, skinless thighs work well and stay very juicy. Just trim excess fat, pound lightly for even thickness, and adjust cooking time since thighs may take a bit longer to cook through.

Can I bake the chicken instead of searing it?

You can. Bake the seasoned chicken at 400°F (200°C) until nearly cooked through, then add the Parmesan crust and broil. Searing first, though, adds more flavor and color to the outside.

What cheese works best for the Parmesan crust?

Parmesan is essential for flavor, but you can mix it with provolone, mozzarella, or even a bit of Monterey Jack. Aim for a blend that melts well while still tasting sharp and cheesy.

Can I prepare this chicken ahead of time?

Yes. You can season and sear the chicken, then refrigerate it. Mix the topping separately. Before serving, bring chicken slightly toward room temperature, add the crust, and broil until hot and golden.

How do I keep the chicken from drying out?

Pound the breasts evenly, avoid overcooking, and let them rest a few minutes before serving. The creamy Parmesan topping also helps lock in moisture and adds richness to each bite.

Serving Ideas for Copycat Longhorn Parmesan Crusted Chicken

This chicken has big, bold flavor, so simple sides let it shine while still feeling like a complete restaurant-style meal. Classic mashed potatoes or garlic butter baby potatoes soak up the cheesy juices beautifully.

For a lighter plate, pair it with roasted green beans, asparagus, or a crisp mixed salad tossed in a lemony vinaigrette. A side of buttered rice, herbed orzo, or even creamy polenta also makes a lovely base under those juicy, crusted chicken slices.

If you’re feeding guests, add warm dinner rolls or a baguette so everyone can swipe up any melted cheesy bits left on the plate. It turns an everyday dinner into a special steakhouse-inspired spread.

Keeping Leftovers Fresh

If you have leftovers, let the chicken cool until just warm, then transfer to an airtight container or wrap tightly. Store in the refrigerator for 3–4 days. The crust will soften slightly, but the flavor stays rich and comforting.

For best results, reheat the chicken in a 325°F (165°C) oven. Place the pieces in a baking dish, cover loosely with foil, and warm until hot in the center. Remove the foil near the end so the topping can re-crisp a little.

You can reheat individual portions in the microwave, but do it in short bursts so the chicken doesn’t overcook. If the crust looks a bit dry, a small spoonful of sour cream on top before reheating can help restore creaminess.

Because of the mayo, sour cream, and cheese, freezing is not ideal; the texture can turn grainy after thawing. Enjoy this dish fresh or within a few days for the best copycat Longhorn Parmesan Crusted Chicken experience.
