Ingredients for Copycat Longhorn Parmesan Chicken

Alright, let’s gather our goodies! Here’s what you’ll need to whip up this amazing Copycat Longhorn Parmesan Chicken. Don’t worry, it’s mostly stuff you probably already have!

4 boneless, skinless chicken breasts – about the same size is best!
1 cup mayonnaise – don’t skimp on the good stuff!
1/2 cup grated Parmesan cheese – fresh is always better, if you can!
1/4 cup bread crumbs – plain or Italian seasoned, whatever you’ve got!
2 tablespoons Dijon mustard – adds a little zing!
1 teaspoon garlic powder – because everything’s better with garlic!
1/2 teaspoon black pepper – freshly ground is my fave!
Salt to taste – don’t be shy!
2 tablespoons olive oil – for searing that chicken to golden perfection!

How to Make Copycat Longhorn Parmesan Chicken

Okay, so here’s the fun part! Let’s actually *make* this amazing Copycat Longhorn Parmesan Chicken! Trust me, it’s easier than you think.

First things first: Preheat your oven to 375°F (190°C). Get that baby nice and toasty!
We’re gonna make the magic sauce! In a bowl (a medium-sized one is perfect), mix together the mayonnaise, Parmesan cheese, bread crumbs, Dijon mustard, garlic powder, pepper, and salt.
Now, coat each chicken breast with that glorious Parmesan mixture. Make sure you get it nice and even on both sides!
Grab an oven-safe skillet (cast iron is awesome if you have one!). Heat up the olive oil over medium heat.
Sear those chicken breasts in the skillet for about 2-3 minutes per side. You just want a little golden crust. Don’t worry about cooking them all the way through just yet!
Now, carefully transfer that skillet straight into the preheated oven. Bake for 20-25 minutes, or until the chicken is cooked through.
Let the chicken rest for about 5 minutes before serving. This helps keep it juicy!

Preparing the Parmesan Crust for the Copycat Longhorn Parmesan Chicken

That Parmesan crust is KEY! You want to get the consistency just right. It should be thick enough to coat the chicken without being clumpy. If it seems too thick, add a *tiny* bit more mayo. Too thin? A little more Parmesan or breadcrumbs will do the trick! Just play around until it looks like a nice, spreadable paste.

Cooking the Copycat Longhorn Parmesan Chicken

Okay, so searing the chicken first is important! It gives it that nice restaurant-style color and seals in the juices. But don’t overcook it! You’re just looking for a little golden action. Then, when you bake it, make sure it reaches an internal temperature of 165°F (74°C). I always use a meat thermometer to be sure! When it’s done, it’ll be juicy and tender, not dry and rubbery. Nobody wants that!

Tips for the Best Copycat Longhorn Parmesan Chicken

Want to take your Copycat Longhorn Parmesan Chicken to the *next level*? Here are a few of my tried-and-true tips!

Don’t overcrowd the pan when you’re searing the chicken. If you try to squeeze too much in, it’ll steam instead of sear. Sad! Work in batches if you need to.
Seriously, get yourself a meat thermometer! It’s the best way to make sure your chicken is cooked perfectly. No guessing games!
Resist the urge to cut into the chicken right away! Letting it rest for 5 minutes after baking lets the juices redistribute, making it extra juicy and delicious.

Ingredient Notes and Substitutions for Copycat Longhorn Parmesan Chicken

Okay, so sometimes you’re missing an ingredient or just wanna switch things up, right? No problem! Here are a few swaps you can make with this Copycat Longhorn Parmesan Chicken:

Mayonnaise: If you’re not a mayo fan (gasp!), try plain Greek yogurt or sour cream. It’ll change the flavor a bit, but still be yummy!
Parmesan: Asiago or Romano cheese would also be tasty. Just make sure it’s grated!
Breadcrumbs: Panko breadcrumbs will give you an extra crispy crust. You can even use crushed crackers in a pinch!

Don’t be afraid to experiment! That’s how you make a recipe your own!
