Ingredients You’ll Need

Each ingredient in this sandwich works in harmony, offering layers of flavor and texture. I always recommend opting for quality bread and fresh chicken for the best result—these simple swaps make a world of difference.

• Butter: Use unsalted butter so you control the saltiness; it helps toast the brioche to golden perfection.
• Brioche slices: Brioche has that soft, slightly sweet crumb that pairs beautifully with savory ingredients.
• Dijon mustard: Adds a tangy bite that cuts through the richness of the jam and cheese.
• Grilled chicken: I like chicken breasts grilled to juicy perfection, sliced about 3/4″ to 1″ thick for hearty bites.
• Mozzarella cheese: Fresh mozzarella melts easily and keeps the sandwich creamy without overpowering the onion jam.
• Divina Caramelized Onion Jam: This is the star—deep, sweet, and jammy, it elevates the whole sandwich experience.
• Salt and pepper: To season your chicken and bring out all the flavors.

Variations

I love switching things up based on mood and season, making this grilled chicken sandwich truly your own. It’s always fun to experiment with ingredient swaps or add-ons to keep the recipe fresh and exciting.

• Variation: Swap mozzarella for provolone or smoked gouda if you want a richer cheese flavor—I tried this once with gouda, and the smoky undertones gave the sandwich a cozy twist.
• Dietary: For a lighter option, swap brioche for whole wheat or sourdough bread to add a bit of tang and fiber.
• Vegetarian: Replace grilled chicken with thick grilled portobello mushrooms—once I made this for a vegetarian friend, and it was a hit!
• Seasonal: During summer, adding some fresh basil or arugula brings a fresh, peppery note that contrasts nicely with the sweet onion jam.

How to Make Grilled Chicken Sandwich with Caramelized Onion Jam Recipe

Step 1: Prep and Season Your Chicken

I always start by seasoning the grilled chicken with a pinch of salt and pepper—nothing fancy, just enough to enhance the natural flavors. If you’re grilling at home, cook it over medium-high heat until the juice runs clear, about 6-7 minutes per side depending on thickness. The key here is to avoid drying it out; juicy chicken makes all the difference in this sandwich.

Step 2: Toast the Brioche with Butter

Now, butter both brioche slices lightly—don’t skimp!—and toast them on a skillet over medium heat until golden brown and slightly crisp. This step is crucial because it adds a bit of crunch and richness that contrasts so well with the tender chicken and sweet onion jam.

Step 3: Assemble with Mustard, Cheese, and Jam

Spread about a tablespoon of Dijon mustard on one slice of the warm brioche, then layer your sliced grilled chicken evenly. Next, add the two slices of fresh mozzarella on top—don’t worry if it starts melting from the warmth of the chicken. Finally, spread two tablespoons of that irresistible caramelized onion jam on the other slice of brioche and bring both pieces together for the ultimate flavor combination.

Garnishes

I usually add some fresh arugula or baby spinach on mine—something peppery and green to cut through the richness. Sometimes a few thin slices of pickles work wonders too, offering a little tang and crunch. These simple touches add freshness and texture without competing with the star ingredients.

Side Dishes

When I serve this sandwich, I often pair it with crispy sweet potato fries or a light side salad. A handful of kettle-cooked chips or some roasted veggies also complement it beautifully if you want to keep things simple. These sides keep the meal balanced and satisfying.

Creative Ways to Present

For a dinner party, try cutting the sandwich into sliders and skewer each with a colorful pick. It’s a crowd-pleaser and makes serving easy. You can also serve the sandwich open-faced with a drizzle of balsamic glaze over the caramelized onion jam for a bit of gourmet flair. I’ve done this for casual gatherings, and it always feels special without extra hassle.

Make Ahead and Storage

Storing Leftovers

If you have leftovers, wrap the sandwich tightly in plastic wrap or foil and pop it in the fridge. I find that keeping the caramelized onion jam separate in a little container helps avoid sogginess overnight. The chicken holds up well, and all the flavors actually deepen after a day.

Freezing

I’ve frozen grilled chicken slices before, but I recommend not freezing the fully assembled sandwich because the bread loses texture. Instead, freeze cooked chicken separately and add fresh onion jam and bread when you’re ready to eat. This keeps everything tasting fresh without the mushy bread problem.

Reheating

To reheat leftovers, unwrap the sandwich and heat it in a skillet over low-medium heat, pressing lightly like a panini. This helps melt the cheese and keeps the chicken moist without drying it out. Avoid the microwave if you want to keep the brioche crispy and that lovely cheesy melt.
