Oven-Baked Pineapple Chicken Recipe: Caramelized Sweetness With Crispy Celery Topping

This oven-baked pineapple chicken recipe transforms simple ingredients into a dish that balances sweet caramelized pineapple with savory, crispy chicken—a restaurant-quality meal you can make at home. The secret lies in marinating the chicken overnight, ensuring tender meat that absorbs the tropical flavors deeply.

I first perfected this technique while catering a summer barbecue, where guests kept asking for seconds.

The crispy celery topping adds a surprising textural contrast, creating a satisfying crunch with every bite. While the chicken bakes, the pineapple releases its natural juices, forming a sticky glaze that caramelizes beautifully in the oven.

This method delivers crispy edges without frying, making it a healthier yet equally delicious alternative to deep-fried versions.

By the time you serve this dish, you’ll have golden-brown chicken with tender, juicy meat and a glossy pineapple glaze that ties everything together. The celery topping adds a fresh, crisp element that cuts through the richness, balancing the sweet and savory perfectly.

It’s the kind of dish that feels special enough for dinner guests but simple enough for a weeknight.

Pair it with steamed jasmine rice or a fresh green salad to round out the meal. The flavors are bold enough to stand alone but versatile enough to complement other sides.

Here’s how to make it—every step designed to ensure that crispy texture and perfect balance of sweetness and savory notes.

Ingredients for oven baked pineapple chicken

Restaurant-quality flavors start with these carefully balanced ingredients for crispy, caramelized pineapple chicken.

The chicken thighs are non-negotiable here—bone-in, skin-on delivers the juiciest results, but boneless skinless works too if that's what you've got. Costco or local butchers often carry pre-cut thighs at better prices than grocery stores. For the pineapple, fresh is ideal but canned in juice (drained) works in a pinch—just avoid syrup-packed versions. The celery topping requires fresh, crisp stalks; avoid wilted or yellowing pieces. Garlic and ginger should be freshly grated or minced for maximum flavor impact—pre-minced jarred versions lack the same punch.

No fresh ginger? Dried works at half the amount, but it's worth tracking down fresh for this dish. Running low on soy sauce? Coconut aminos or tamari are excellent substitutes, though the flavor profile shifts slightly. The celery topping can be prepped ahead—mix flour, cornstarch, and butter the night before and store in an airtight container. For the brown sugar, coconut sugar adds subtle caramel notes. The marinade should coat the chicken thoroughly—reserve 2 tbsp to brush on during baking for extra shine and flavor.

Marinated chicken keeps 24 hours in the fridge, allowing flavors to develop fully. The celery topping mixture stays fresh 3 days refrigerated, though it's best used immediately for peak crispiness. Baked chicken reheats beautifully—cover with foil and warm in a 350°F oven for 10 minutes. For meal prep, portion the pineapple glaze separately and reheat with the chicken to maintain its glossy texture. Store leftovers in airtight containers for up to 4 days—the flavors actually improve overnight as the pineapple juices meld with the chicken.

Step-by-step instructions for oven-baked pineapple chicken

This recipe delivers caramelized sweetness with a perfectly crisp celery topping—every element works together for maximum flavor and texture.

In a large bowl, combine the 2 cups fresh pineapple chunks, 0.5 cup soy sauce, 0.5 cup packed brown sugar, 6 minced garlic cloves, 2 tablespoons grated fresh ginger, 0.25 cup freshly squeezed lime juice, 1.5 teaspoons kosher salt, and 1 teaspoon freshly ground black pepper. Mix thoroughly until the brown sugar dissolves completely.

Cut the 1.5 lb boneless, skinless chicken thighs into even-sized pieces and add them to the marinade. Ensure each piece is fully coated by stirring gently. Cover the bowl and refrigerate for at least 4 hours or overnight—this long marinating time allows the flavors to deeply penetrate the chicken, creating a perfectly balanced sweet-savory profile.

Preheat your oven to 375°F. Transfer the marinated chicken (including any accumulated juices) to a baking dish. Spread the pieces in a single layer, ensuring they don't overlap. Bake uncovered for 35-40 minutes, or until the internal temperature reaches 165°F and the chicken is golden brown with caramelized edges.

I recommend checking the chicken at the 30-minute mark—if the edges are browning too quickly, tent loosely with foil to prevent over-browning while ensuring it cooks through. The caramelized glaze should be sticky and slightly crisp, indicating perfect sweetness.

While the chicken bakes, melt the 2 tablespoons unsalted butter in a small skillet over medium heat. Add the 4 whole celery stalks, thinly sliced, and cook for 2-3 minutes until softened. Stir in the 0.5 cup all-purpose flour and 2 tablespoons cornstarch, cooking for another 1-2 minutes until the mixture thickens into a paste.

Remove from heat and let cool slightly. This crispy celery mixture will add a delightful textural contrast to the tender chicken, balancing the sweetness with a savory crunch. The flour and cornstarch create a light, golden crust that stays crisp even after baking.

Once the chicken is fully cooked, sprinkle the crispy celery mixture evenly over the top of each piece. Return the baking dish to the oven and broil for 2-3 minutes, watching closely to ensure the celery topping becomes golden brown and crispy without burning.

Broiling at the end intensifies the caramelization and creates that perfect crispy texture we're aiming for. Serve immediately while the chicken is juicy and the celery topping is still crunchy—this dish tastes best straight from the oven when all the flavors are at their peak.

Dietary considerations for this recipe

Gluten-Free Adaptation

Replace the 0.5 cup all-purpose flour in the crispy celery topping with 0.5 cup gluten-free all-purpose flour blend like Bob's Red Mill 1:1. The 2 tbsp cornstarch can stay the same since it's naturally gluten-free.

I've tested this with my favorite King Arthur gluten-free blend, and it creates the same crispy texture without compromising flavor. 🌾

Dairy-Free Option

For a dairy-free version, swap the 2 tbsp unsalted butter in the celery topping with 2 tbsp coconut oil or dairy-free margarine. The flavor remains neutral enough that it won't interfere with the pineapple and soy notes.

I often use Earth Balance dairy-free butter sticks for this purpose—they melt beautifully and create the same crispy coating.

Lower Sugar Version

Reduce the 0.5 cup packed brown sugar to 0.25 cup and add 2 tbsp monk fruit sweetener or 1 tbsp erythritol to maintain sweetness without the same calorie impact.

The pineapple's natural sugars will still caramelize, just with less added sweetness. This version works beautifully for those watching sugar intake while keeping the dish's signature sweet-savory balance.

Protein Swaps

For a seafood variation, use 1.5 lb firm white fish fillets like cod or halibut instead of chicken. The cooking time reduces to 15-20 minutes at 375°F, and you'll want to broil for just 1-2 minutes to crisp the celery topping.

I've made this with mahi-mahi for summer gatherings, and it's a crowd-pleaser with the same tropical flavors.

Allergy-Friendly Notes

This recipe is naturally soy-free if you substitute tamari for soy sauce, and nut-free as written. For egg allergies, no modifications are needed since we're not using any egg-based ingredients.

Always double-check your flour blend for cross-contamination warnings if gluten is a concern—many gluten-free products are processed in facilities that handle soy and dairy.
