This Grilled Hawaiian Chicken Sandwich has been a backyard staple in our family for years and always signals the start of summer barbecues. I discovered this combination one humid July when I was looking to use a can of pineapple and two chicken breasts that were about to be forgotten in the fridge. The balance of salty soy, brown sugar sweetness, and bright pineapple acidity turned a simple sandwich into something memorable. The texture contrast—juicy grilled chicken with a lightly charred pineapple ring and melted provolone—makes every bite sing, and even the pickiest teenager at our table asks for seconds. What makes this preparation special is its simplicity and reliability: a short active prep, a long, forgiving marinade, and quick grill time that delivers consistent results. Because the chicken is pounded to an even thickness and marinated in the pineapple-laced sauce, it stays tender and absorbs flavor all the way through. The mayo-brushed buns add creaminess and a slight tang that ties the sweet and savory elements together. I often serve these with a crisp slaw or simple green salad, and they travel wonderfully to picnics and potlucks.

Ingredients

• Boneless, skinless chicken breasts (2 x 6-ounce): Choose firm, evenly sized breasts; slicing each in half yields four thinner cutlets that grill evenly. If available, buy fresh from the meat counter for consistent thickness.
• Coarse salt and black pepper: Simple seasoning brings out the chicken’s flavor. Use kosher or sea salt for the best texture; grind fresh black pepper for aroma.
• Garlic powder (1/4 teaspoon): Adds a subtle savory backbone without overpowering the sweet marinade—prefer this to fresh garlic for a cleaner, more stable flavor when grilling.
• Pineapple rings (8-ounce can or fresh): Canned pineapple in juice is convenient and helps form the marinade. If using fresh, look for ripe fruit with a sweet aroma and firm flesh; pat dry to avoid excess moisture on the grill.
• Soy sauce (2 tablespoons, low sodium): Provides umami and salt; low-sodium avoids over-salting during marination. Tamari works as a gluten-free alternative.
• Brown sugar (2 tablespoons): Creates caramelization on the pineapple and chicken—light or dark both work, dark will deepen the molasses notes.
• Dijon mustard (2 teaspoons): Adds a faint sharpness that balances the sweetness without being prominent—helps emulsify the marinade.
• Provolone cheese (4 slices): Melts smoothly and adds a mild, creamy layer on top of the chicken; Swiss or provolone both make excellent alternatives.
• Buns or kaiser rolls (4): Select sturdy rolls that can hold the juices; toast them lightly on the grill for texture and flavor.
• Mayonnaise (1/4 cup): Provides richness and seals the bun against moisture—use light mayo if you prefer a less heavy finish.

Instructions

Prepare the poultry: Pound the breasts to an even 1-inch thickness if they’re thicker, then slice each breast in half to make four pieces. Even thickness ensures uniform cooking; place poultry between plastic wrap and use a flat mallet or heavy skillet. Season both sides with 1/2 teaspoon coarse salt, 1/4 teaspoon black pepper, and 1/4 teaspoon garlic powder so the surface is lightly but evenly coated. Mix the marinade: Combine the liquid from the 8-ounce can of pineapple (or 1/4 cup fresh pineapple juice) with 2 tablespoons low-sodium soy sauce, 2 tablespoons packed brown sugar, and 2 teaspoons Dijon mustard. Whisk until the sugar dissolves. The pineapple juice contains enzymes that will tenderize, while soy and sugar build flavor and color when grilled. Marinate: Place the seasoned poultry in a shallow dish or resealable bag and pour the marinade over it. Press out excess air and refrigerate for at least 12 hours, ideally overnight. The long marination softens fibers and infuses flavor; avoid marinating more than 24 hours to prevent the meat from becoming mushy due to pineapple enzymes. Preheat and prepare the grill: Set up for medium-high heat (around 400F surface temperature). Clean and oil the grates well to prevent sticking—use a paper towel dipped in oil and long-handled tongs. If using a grill pan, preheat it over medium-high and brush with oil. Grill chicken and pineapple: Grill the poultry 12 to 15 minutes total, flipping once halfway, until an instant-read thermometer reads 165F in the thickest part. Add the pineapple rings to the grill halfway through grilling; turn once so each ring gets nice char marks. With about 3 minutes remaining, place a slice of provolone on each piece of poultry so it melts as the meat finishes cooking. Assemble the sandwiches: Lightly toast the buns on the grill, spread about 1 tablespoon of mayonnaise on each bun, top with a piece of chicken, and finish with a grilled pineapple ring. Serve immediately to enjoy the contrast of hot, melted cheese and juicy fruit against the creamy bun.

Storage Tips

Store any leftover grilled poultry and pineapple in an airtight container in the refrigerator for up to 3 days. Keep buns separate to avoid sogginess; if you must store assembled sandwiches, wrap them in parchment paper and place them in a shallow container to limit crushing. To freeze, place cooled grilled chicken and pineapple in a single layer on a sheet tray to flash-freeze, then move to a freezer bag for up to 3 months. Reheat frozen portions gently in a skillet over medium-low heat with a lid to prevent drying—add a splash of water and cover briefly to restore moisture.

Ingredient Substitutions

If you need a gluten-free option, swap regular buns for gluten-free rolls or large butter lettuce leaves for a low-carb wrap. For a dairy-free version, omit the provolone and use a dairy-free melting slice or a smear of mashed avocado. If soy is a concern, use coconut aminos in place of soy sauce—adjust salt since coconut aminos are milder. Pineapple can be swapped for mango slices for a tropical twist, though mango won’t caramelize in the same way; reduce marinade time with fresher, softer fruit to avoid over-tenderizing the poultry.

Serving Suggestions

Serve with crisp coleslaw, a cucumber and tomato salad, or sweet potato fries to balance the juicy, sweet-savory sandwich. Garnish with fresh cilantro or thinly sliced scallions for brightness. For a casual gathering, set up a build-your-own sandwich station with extra grilled pineapple, pickled red onions, and an assortment of cheeses. A chilled crisp lager or a citrus-forward iced tea pairs well—aim for beverages that refresh the palate between bites of caramelized sweetness.

Seasonal Adaptations

In summer, use ripe fresh pineapple cut into rings or thick wedges—pat dry to encourage caramelization. For cooler months, canned pineapple still offers great flavor; drain well and reserve the juice for the marinade. Add seasonal accents like grilled peaches in late summer or a smear of cranberry mustard for a holiday twist. You can also swap the poultry for thin pork cutlets and keep the rest of the profile the same for a different but equally comforting seasonal option.

Meal Prep Tips

Marinate the poultry overnight and grill all pieces at once; cool and store in meal-sized portions for quick assembly during the week. Pack buns separately and bring a small container of mayo to keep the bread from getting soggy. Reheat grilled chicken in a skillet over medium heat with a splash of water and a lid to steam gently before adding cheese to melt. This approach yields restaurant-quality sandwiches in under 10 minutes on busy evenings.

These sandwiches are a dependable, joyful addition to any summer table—bright, comforting, and easy to adapt. Invite friends, fire up the grill, and let the caramelized pineapple do the rest. Enjoy—and don’t forget to save a ring for yourself!
