Garlic parmesan chicken sandwiches on buttery brioche buns are the kind of dinner that disappears from the table before you have a chance to sit down.
The chicken gets cubed and seasoned, then seared until golden, bathed in a creamy garlic parmesan sauce, and finished in the oven until the cheese melts into something you want to eat with a spoon.
Tucked between toasted brioche with crispy bacon on top, each bite hits you with crunch, creaminess, salt, and that unmistakable roasted garlic flavor.
- If you have been relying on the same chicken sandwich rotation, this one changes the game without requiring any hard-to-find ingredients.
The secret weapon here is the garlic parmesan sauce. Using a store-bought version like Buffalo Wild Wings saves you time while delivering that restaurant-quality taste. The rest of the ingredients are things you probably already have in your kitchen.
From prep to plate, you are looking at about 50 minutes, and most of that is hands-off oven time.

What to Expect When You Bite In
The first thing you notice is the buttery crunch of the toasted brioche giving way to the creamy, garlicky chicken mixture. The sauce is rich and tangy with a sharp parmesan bite, while the chicken stays juicy inside its seasoned crust.
Crispy bacon adds a smoky snap that cuts through the creaminess. The red pepper flakes give just enough warmth to notice without making you reach for water.
It is messy in the best way, with sauce that drips down your fingers and bacon that threatens to slide out the side.
Ingredients You’ll Need
For the chicken:
– 1.25 lbs chicken breast, cut into 1-inch cubes – cubing the chicken ensures every piece cooks quickly and evenly, and more surface area means more seasoning in every bite
– 3/4 teaspoon salt – brings out the natural flavor of the chicken
– 3/4 teaspoon black pepper – adds a mild heat that works well with the garlic
– 1 1/2 teaspoons garlic powder – layers garlic flavor into the meat itself, not just the sauce
– 1 1/2 teaspoons paprika – gives the chicken a warm, reddish color and a subtle smokiness
– 1 teaspoon onion powder – adds depth without the bite of raw onion
– 1/4 teaspoon red pepper flakes – a gentle heat that balances the richness of the sauce and cheese
– 1 tablespoon olive oil – for searing; a neutral oil with a high smoke point works too
– 2/3 cup garlic parmesan sauce – Buffalo Wild Wings brand is ideal, but any creamy garlic parmesan sauce works
– 3/4 cup parmesan cheese, freshly shredded – freshly grated melts into the sauce smoothly; pre-shredded has anti-caking additives that make it grainy
– 1 tablespoon fresh parsley, finely chopped – brightens each sandwich with color and a mild, fresh flavor
For the bacon:
– 8 slices thick-cut bacon – thick-cut holds its crispness better inside the sandwich
For assembly:
– 4 brioche buns – brioche is soft but sturdy enough to hold the saucy filling; lightly toast them so they do not fall apart
– 3 tablespoons butter, softened – spread on the buns before toasting for a golden, flavorful crust
When you are at the store, pick chicken breasts that are roughly the same size so the cubes cook evenly. For the bacon, thick-cut is worth it here because thin bacon goes limp the second it hits the sandwich. If you cannot find garlic parmesan sauce at your grocery store, you can make a quick version by combining 1/4 cup melted butter with 3 minced garlic cloves, 1/4 cup grated parmesan, and a pinch of Italian seasoning.
Swaps That Work
- Chicken thighs instead of breasts – more forgiving and stay juicier; just trim the excess fat before cubing
- Rotisserie chicken – shred it and toss with the sauce for a 15-minute version of this recipe
- Turkey bacon – saves about 30 calories per slice and still gets crispy
- Different buns – potato rolls, kaiser rolls, or ciabatta all work; just make sure whatever you use can hold up to a saucy filling
- Homemade garlic parmesan sauce – mix melted butter, minced garlic, grated parmesan, and Italian seasoning as mentioned above
Gear You Will Want
- Large oven-safe skillet – for searing the chicken and finishing it in the oven
- Baking sheet with foil – for the bacon
- Small bowl – for mixing the seasoning blend
- Tongs – for flipping the chicken and handling the bacon
- Meat thermometer – the chicken should hit 165 degrees F internally
Let’s Cook This Step by Step
While your finished dish may not look exactly like the images in this post, following these instructions will give you the same delicious BRIOCHE GARLIC PARMESAN CHICKEN SANDWICHES. So please follow with me!
Start by cutting the chicken breasts into 1-inch cubes. Try to keep them uniform in size so they all finish cooking at the same time. In a small bowl, combine the salt, black pepper, garlic powder, paprika, onion powder, and red pepper flakes.
Toss the cubed chicken with this seasoning mix until every piece is evenly coated. This dry seasoning creates a flavorful crust when the chicken hits the hot oil.
Get the bacon going first since it takes the longest. Lay the strips on a foil-lined baking sheet and slide it into a 400 degree F oven.
After about 25 minutes, the bacon should be deeply golden and crispy. Remove it and drain on paper towels. Once it cools slightly, break or chop it into bite-sized pieces.
- While the bacon cooks, heat 1 tablespoon of olive oil in your large skillet over medium-high heat. Wait until the oil is shimmering before adding the chicken.
Spread the cubes in a single layer and let them sear undisturbed for 3 to 4 minutes. That golden-brown crust is where the best flavor comes from, so resist the urge to move them around. Flip each piece and sear for another 2 to 3 minutes until browned on all sides.
Work in batches if your skillet is crowded because overcrowding causes the chicken to steam instead of sear. According to Serious Eats’ guide to searing meat, that Maillard reaction on the surface is what creates those complex, savory flavors.
Once the chicken is seared, pour the garlic parmesan sauce directly over it in the skillet and toss to coat every piece. Sprinkle the freshly shredded parmesan cheese on top and stir gently.
- Transfer the whole skillet to the 400 degree F oven and bake for 10 to 15 minutes.
You are looking for the chicken to reach an internal temperature of 165 degrees F and the cheese to be melted and slightly golden. The oven finish lets the cheese melt evenly and the sauce caramelize a bit around the edges.
While the chicken finishes, prepare the buns. Spread softened butter on the inside of each brioche bun. Heat a clean skillet over medium heat and toast the buttered buns for 1 to 2 minutes until lightly golden and crisp on the inside.
This step matters more than you might think. The toasted butter creates a waterproof barrier so the sauce does not soak through and make the bun soggy. It also adds a layer of flavor that ties everything together.
To assemble, lay out the toasted buns on a serving plate. Divide the garlic parmesan chicken mixture evenly among the four bottom buns, spooning on any extra sauce left in the skillet.
Top each portion with the chopped bacon pieces and a sprinkle of fresh parsley. Cap each sandwich with the top bun and serve immediately while the cheese is still stretchy and the bacon is still crisp.

Small Details That Matter
Pull the chicken from the oven when your thermometer reads 160 degrees F and let it rest for 5 minutes. Carryover cooking will bring it up to 165 degrees F while keeping it juicy.
If you leave it in until the thermometer hits 165, it will overcook by the time you serve it. For a deeper dive into safe cooking temperatures, the USDA’s poultry safety guidelines are worth bookmarking.
Do not skip the bun toasting step. Untoasted brioche turns into a soggy mess within minutes once the saucy chicken sits on it. The butter-toasted interior holds up beautifully and adds its own flavor.
When you sear the chicken, give the pan time to get hot before adding the oil, and give the oil time to shimmer before adding the chicken. A cold pan means steamed chicken instead of seared chicken. For more techniques that improve everyday cooking, browse our dinner recipes.
If Something Goes Wrong
Chicken is dry. You likely overcooked it. Next time, pull it at 160 degrees F internally and let carryover heat do the rest. For now, the garlic parmesan sauce will help mask the dryness.
Sauce is too thick or pasty. Stir in a tablespoon of milk or chicken broth to thin it out. Some brands of garlic parmesan sauce are thicker than others, so adjust as needed.
Bacon is not crispy. If your oven runs cool, add 5 more minutes. You can also finish it under the broiler for 1 to 2 minutes, but watch it carefully because bacon goes from crispy to burnt very quickly.
Buns are falling apart. You may not have toasted them long enough, or you used buns that are too soft. Brioche and potato rolls hold up best. For sturdier options, try ciabatta or a crusty roll.
Ways to Make It Your Own
- Spicy version: Double the red pepper flakes in the seasoning and add a dash of hot sauce to the garlic parmesan sauce
- Lighter version: Use turkey bacon, skip the butter on the buns, and use half the cheese
- Air fryer chicken: Season the cubes the same way and air fry at 380 degrees F for 10 to 12 minutes, then toss with the sauce
- Sliders: Use slider buns and reduce the chicken per sandwich for a party-friendly option
- Add greens: Tuck a handful of arugula or baby spinach into each sandwich for freshness and crunch
What Goes Well on the Side
These sandwiches are hearty, so keep the sides simple. Crispy french fries or sweet potato fries are the obvious choice and perfect for dipping in any leftover garlic parmesan sauce.
- A light coleslaw adds crunch and acidity that balances the richness.
Pickle spears cut through the creaminess with their vinegary tang. For a complete meal spread, pair these with our creamy garlic chicken as an alternative main course, or explore more ideas in our healthy recipes section for lighter side dishes.
Storage and Leftovers
Refrigerator: Keep leftover chicken in an airtight container separate from the buns for up to 3 days. The bacon can be stored with the chicken, but keeping the buns separate prevents them from getting soggy.
Freezer: The cooked chicken freezes well for up to 2 months. Let it cool completely, wrap portions individually, and place in a freezer bag. Do not freeze the assembled sandwiches because the buns will not hold up.
Reheating: Warm the chicken in a skillet over medium heat for a few minutes on each side, or microwave for 60 to 90 seconds. Add a little extra sauce when reheating to keep it moist. Toast fresh buns with butter and assemble right before eating for the best results.
Questions You Might Still Have
Can I use chicken tenders instead of breasts? Yes, chicken tenders work great and actually cook faster. Just reduce the searing time by about a minute per side.
What if I cannot find garlic parmesan sauce? Make a quick version by combining 1/4 cup melted butter, 3 minced garlic cloves, 1/4 cup grated parmesan, and a pinch of Italian seasoning. It will not be exactly the same, but it will be delicious.
Can I make the chicken ahead of time? You can season and cube the chicken up to 24 hours in advance and keep it covered in the fridge. Cook it when you are ready to eat for the best texture.
Is there a way to make this less rich? Use half the sauce, skip the bacon, and serve on a regular whole wheat bun instead of brioche. You will still get great flavor with significantly less fat.
These garlic parmesan chicken sandwiches are worth every minute of prep. The combination of seared, seasoned chicken, creamy sauce, and crispy bacon on a butter-toasted brioche bun is the kind of meal that makes everyone at the table happy.
