The day that a waitress from Longhorn wrote down their prized Parmesan-crusted topping, was the day I died and went to heaven. 

This was over five years ago, before I had a food blog, and I kind of forgot that I had this recipe. (Which is odd because it’s amazing. Beyond amazing.) Well anyway, I’m here to share the wealth with you.

But first, the marinade. Hold the phone. Because the flavor of this marinade is amazing. It definitely gives my current go-to chicken marinade a run for its money. Let’s do this.

Of course you can prepare this chicken on the grill, but for an all-year-round version, I like to sear it. I have strong opinions about how delicious seared chicken can be.

How to Make Perfectly Seared Chicken

✔️Cast iron skillets conduct heat very well and are perfect to use when searing meat.

✔️Medium-high heat works well for searing, and it’s important to use oil with a high smoke point such as vegetable, canola, or peanut oil to prevent the meat from burning.

✔️It’s important to refrain from moving the meat around as it cooks. Allowing the meat to stay in the same place in the skillet ensures that the sear isn’t disrupted. You’ll notice that the chicken starts to release from the surface when it’s ready. If it’s sticking a lot to the pan, it’s not done searing.

✔️Butterfly the chicken or pound it thin to create pieces of equal size. This will allow them to cook evenly and prevent them from being too thick.

Substitute for Provolone

Mozzarella makes an acceptable substitute for provolone in this recipe.

1/3 mozzarella and 2/3 muenster cheese is an even closer replicate.

Storing Leftovers

Leftovers should be refrigerated and should be used within 3 days.

This Copycat version of Longhorn's famous Parmesan Crusted Chicken tastes just like the restaurant! From the flavorful marinade, to the creamy, crunchy Parmesan Crust.

  • 4 skinless/boneless chicken breasts pounded to ¾ inch thick
  • Salt/Pepper to taste
  • 2 Tablespoons vegetable oil
  • 1/2 cup olive oil
  • 1/2 cup ranch dressing
  • 3 tablespoon Worcestershire sauce
  • 1 teaspoon vinegar
  • 1 teaspoon lemon juice
  • 1 tablespoon minced garlic
  • 1/2 teaspoon pepper
Parmesan Crust
  • 3/4 cup Parmesan cheese chopped into bits
  • 3/4 cup Provolone cheese chopped into bits
  • 6 Tablespoons Buttermilk Ranch salad dressing
  • 1 cup panko
  • 2 teaspoons garlic powder
  • 5 Tablespoons melted butter
  1. Whisk all marinade ingredients together until well-combined and uniform in consistency.
  2. Place the chicken in a gallon freezer bag, remove the air, and seal. Use a meat mallet to pound it to ¾ inch thick.
  3. Sprinkle each side of the chicken lightly with salt and pepper if desired.
  4. Place the chicken in a new freezer bag along with the marinade. Seal out the air and refrigerate for a minimum of 30 minutes, or overnight.
  5. Heat 2 Tablespoons of vegetable oil in a cast iron skillet over medium-high heat.
  6. Sear the chicken in the hot skillet on each side. Refrain from moving the chicken around as it sizzles, it will hinder the nice golden sear color. If the pan gets too hot, reduce the heat to medium. Each side will take 3-5 minutes. Once each side is a nice, golden brown and the middle is cooked, set the chicken aside.

Parmesan Crust
  1. Preheat the oven to a low broil.
  2. Combine the chopped Parmesan, Provolone, and Buttermilk Ranch dressing in a small bowl.
  3. Microwave for 30 seconds.
  4. Use the back of a fork to mash and stir the cheese around until they’re about the consistency of lumpy mashed potatoes.
  5. Microwave for an additional 15 seconds. Stir, and spread on top of the chicken.
  6. Combine the panko with the garlic powder. Stir in the melted butter, this allows the Panko topping to brown, otherwise it can immediately burn. Top the chicken with it.

  7. Broil 1-2 minutes until the cheese is hot and melted, keep a close eye to ensure it doesn't burn.

  8. Serve with mashed potatoes and enjoy!

The chicken can also be grilled instead of searing.
