The dish comes together with just a handful of pantry staples, making it perfect for weeknight dinners or meal prep.

By the time you pull these golden-brown thighs from the oven, you’ll have tender, flavorful chicken with a glossy pineapple glaze that’s sticky-sweet and slightly caramelized. The crispy celery topping adds texture that elevates every bite, turning a simple baked dish into something special.

Ingredients for baked pineapple chicken thighs

Transform simple pantry staples into restaurant-quality baked pineapple chicken thighs with crispy celery topping.

The chicken thighs are the foundation—look for bone-in, skin-on cuts at Whole Foods or your local butcher for optimal flavor and moisture retention. Trim excess fat to ensure crispiness without greasiness. Fresh pineapple is non-negotiable; canned varieties lack the vibrant sweetness needed for caramelization. For the celery, select crisp stalks with vibrant green tops—they’ll hold their crunch better when baked. The garlic and ginger should be freshly grated or minced for maximum aromatic impact, as pre-minced versions lose potency quickly.

No fresh pineapple? Freshly squeezed pineapple juice from a can works in a pinch, though it lacks the natural sweetness. Substitute honey with maple syrup if needed, though the flavor profile will shift slightly. For the celery topping, thinly sliced leeks can mimic the texture if celery is unavailable. The soy sauce can be swapped for coconut aminos for a gluten-free option, though the flavor will differ. If you prefer less sweetness, reduce the honey to 2 tablespoons and add an extra ½ teaspoon of grated ginger for balance. The cornstarch is essential for achieving that glossy, caramelized glaze—don’t skip it.

Marinate the chicken overnight in a sealed container in the fridge for optimal flavor penetration. The pineapple glaze can be prepped 2 days ahead and stored in the refrigerator, though it thickens slightly over time. For the crispy celery topping, toast the butter separately to prevent burning when baking. Leftovers keep for 3-4 days in the fridge, though the celery topping loses crispness after 1 day. Reheat gently in a 350°F oven for 10-15 minutes to restore texture.

Step-by-step instructions for baked pineapple chicken thighs

Here's the method for achieving perfectly caramelized glaze and crispy celery topping every time.

In a large bowl, combine the 1.5 lb boneless, skinless chicken thighs, 1 cup fresh pineapple chunks, 4 cloves minced garlic cloves, 1 tbsp grated fresh ginger, 2 tbsp extra-virgin olive oil, 0.25 cup soy sauce, 1.5 tsp Diamond Crystal kosher salt, and 0.5 tsp freshly cracked ground black pepper. Use your hands to gently coat each piece of chicken with the marinade, ensuring the pineapple releases its juices and permeates the meat.

Transfer the chicken to a resealable plastic bag, seal tightly, and refrigerate for at least 4 hours or overnight. This extended marination breaks down the proteins and infuses the chicken with tropical sweetness and savory depth. The pineapple's acidity will tenderize the chicken while the garlic and ginger create complex aromatic layers.

In a medium saucepan, combine 0.5 cup granulated sugar, 0.25 cup honey, 1 tbsp cornstarch, and 0.25 cup soy sauce. Cook over medium-high heat, stirring constantly with a wooden spoon, until the mixture reaches a gentle boil. You'll notice it thickens dramatically as the sugar caramelizes and the cornstarch activates.

Continue cooking for 3-4 minutes until the glaze reaches a soft-ball stage when tested with a candy thermometer (235-240°F). It should be thick enough to coat the back of a spoon but still pourable. Remove from heat immediately and set aside—this glaze will continue thickening as it cools, so don't overcook it or it will become too stiff.

Preheat your oven to 400°F. Remove the chicken from the marinade (reserve the marinade for later) and place the thighs in a single layer on a parchment-lined baking sheet. Spread the caramelized glaze evenly over the chicken, coating all sides completely. Bake for 25-30 minutes until the chicken reaches an internal temperature of 165°F and develops a deep golden-brown crust.

Here's the thing—don't skip basting the chicken with the reserved marinade halfway through baking. After 15 minutes, remove the chicken from the oven and spoon the reserved marinade over the tops. Return to the oven and continue baking. This ensures maximum flavor penetration and prevents the chicken from drying out in the hot oven.

While the chicken bakes, prepare the celery topping by thinly slicing the 3 whole celery stalks into matchsticks. In a small skillet, melt 1 tbsp unsalted butter over medium heat. Add the celery and cook for 5-6 minutes, stirring occasionally, until the celery softens slightly but remains crisp. Season with a pinch of kosher salt and black pepper to taste.

The key to perfect celery topping is patience—don't walk away. Watch closely as the celery transforms from raw to golden brown at the edges. You want it to maintain its crisp texture while developing a subtle caramelization. If it starts to brown too quickly, reduce the heat slightly. Remove from heat and set aside, keeping it warm until serving.

Once the chicken reaches 165°F internally, transfer it to a serving platter. Spoon any remaining glaze from the baking sheet over the chicken and arrange the crispy celery topping evenly on top. Garnish with 0.25 cup chopped fresh parsley for a pop of color and freshness that contrasts beautifully with the caramelized glaze.

Let the chicken rest for 5 minutes before serving—this allows the juices to redistribute throughout the meat, ensuring each bite is moist and flavorful. The contrast of textures will delight your guests: tender chicken, sweet-tangy glaze, crispy celery, and fresh parsley. Serve immediately with steamed rice or roasted vegetables to soak up all that delicious sauce.

Pro cooking tips for this dish

Marinade Magic

Never underestimate the power of overnight marinating—this is where the real flavor transformation happens. I learned this the hard way when I tried baking the chicken straight from the fridge, and it came out dry and bland.

The pineapple’s natural acidity tenderizes the chicken while the garlic and ginger infuse deeply. For best results, use a resealable plastic bag—it ensures the marinade coats every surface of the chicken evenly. 🌟

Glaze Timing

The glaze is delicate—cook it too long and it turns grainy; too short and it won’t caramelize properly. I use a candy thermometer to hit 235-240°F for that perfect soft-ball stage. If you don’t have one, test by dropping a bit into cold water—it should form a thick, pliable ball.

Let it cool slightly before brushing on the chicken, or it’ll steam off instead of sticking.

Basting for Juiciness

That mid-bake basting with reserved marinade is non-negotiable for juicy chicken. I remember my first attempt without it—dry as a bone! After 15 minutes in the oven, pull the chicken out and spoon that flavorful marinade over the tops.

The high heat will quickly seal in moisture and deepen the caramelization. Trust me, this step makes all the difference.

Celery Crisp Perfection

Thin, even slices are key for crispy celery—use a mandoline if you’re not confident with your knife skills. Cook it low and slow in butter until just tender-crisp, about 5-6 minutes. Overcooking turns it mushy, and nobody wants that.

A pinch of salt at the end brings out the natural sweetness while keeping it crisp. This is my grandmother’s trick—she swore by it for adding texture to any dish.

Resting Matters

I know, it’s tempting to dig in immediately, but letting the chicken rest for 5 minutes after baking lets the juices redistribute. This means no dry bites when you cut in! I’ve seen too many cooks skip this step and end up with disappointing results.

Use this time to plate your sides—it’s the perfect opportunity to set the table and get everything ready for serving.

Oven Temperature

Your oven might run hot or cold—400°F is the target, but I always check with an oven thermometer. If your chicken browns too quickly, reduce to 375°F and add 5-10 minutes to the baking time.

The goal is even cooking with a golden crust. Pro tip: Place your baking sheet on the middle rack for consistent heat distribution. This ensures the glaze caramelizes beautifully without burning. 🔥
