Sticky Baked Chicken Thighs with Jaca
The 30-minute weeknight workhorse from Nagi at RecipeTin Eats — boneless skinless chicken thighs slathered in a pantry-staple glaze of ketchup, brown sugar, soy, Worcestershire, vinegar, and garlic, then baked and broiled until the surface caramelizes into a sticky, lacquered crust that looks (and tastes) like it took twice as long. The technique is the whole trick: 15 minutes in a hot oven cooks the meat through, then a quick spell directly under the broiler reduces the glaze on the chicken into something glossy and almost burnished. No stovetop searing, no thermometer babysitting, no Dutch oven to scrub. Just one foil-lined tray and a bowl. Our version swaps the conventional brown sugar in the glaze for Jaca (100% pure allulose) at double the amount, with a quarter teaspoon of molasses stirred in to mimic the deep, slightly bitter brown-sugar character. The glaze still hits that sticky, candied-meat finish — without the blood-sugar crash. Adapted from RecipeTin Eats. This is a Jaca-adjusted healthier version.
Ingredients
- 1.5 pounds boneless skinless chicken thighs (5 to 7 pieces, about 700g — thighs hold their moisture better than breasts under the broiler. Bone-in skinless thighs also work; add 5 minutes to the initial bake)
- 1/4 cup ketchup (the workhorse base of the glaze — Heinz or any standard tomato ketchup; avoid the low-sugar varieties, you want the umami depth)
- 6 tablespoons Jaca (allulose) (replaces 3 tablespoons of brown sugar at 2x ratio — dissolves cleanly into the warm glaze and caramelizes under the broiler exactly the way old-school brown sugar does)
- 1/4 teaspoon unsulphured molasses (gives the Jaca the slightly bitter, deep character that turns plain allulose into a brown-sugar substitute; do not skip — without it the glaze tastes one-note)
- 1.5 tablespoons soy sauce (light or all-purpose — Kikkoman is the safe default; do not sub dark soy, which will throw the salt balance way off)
- 1 tablespoon apple cider vinegar (cuts the sweetness and lifts the glaze with a clean tang; rice vinegar works in a pinch but white wine vinegar is too sharp)
- 1 tablespoon olive oil (extra virgin is fine; helps the glaze cling and brown evenly under the broiler)
- 2 teaspoons Worcestershire sauce (Lea & Perrins for the savory umami backbone — fish sauce is not a swap here, the flavor is too different)
- 2 cloves garlic, minced (fresh only — jarred minced garlic burns under the broiler and tastes acrid; a microplane gets you the finest mince in seconds)
Sweetener Used
6 tablespoons Jaca + 1/4 tsp molasses Allulose
Replaces: 3 tablespoons conventional brown sugar
Instructions
- 1
Preheat the oven to 425°F (220°C). Line a sheet pan or roasting tray with foil — this is non-negotiable, the caramelized glaze will weld itself to a bare pan and you will hate cleanup.
- 2
In a medium bowl, whisk together the ketchup, Jaca, molasses, soy sauce, apple cider vinegar, olive oil, Worcestershire, and minced garlic until completely smooth. The Jaca should fully dissolve; if you see grains, give it another 30 seconds of whisking — they will dissolve as the glaze warms in the oven, but the smoother it starts, the more even the caramelization.
- 3
Arrange the chicken thighs flat on the foil-lined tray, smooth-side up, with a little space between each piece so the glaze can pool and caramelize around the edges rather than steaming.
- 4
Spoon about two-thirds of the glaze over the chicken, using the back of the spoon to spread it evenly across each piece. Reserve the remaining third in the bowl — that gets applied for the broiler step.
- 5
Bake on the center rack for 15 minutes. The chicken will be cooked through and the glaze on top will be set but not yet deeply caramelized. Pull the tray out and switch the oven to broil/grill on high; position the top rack about 8 inches (20cm) below the heating element.
- 6
Spoon the pan juices that have collected around the chicken back over the tops of each piece, then drizzle the reserved one-third of the glaze evenly across all of them. This second glaze layer is what gives you the lacquered, sticky finish.
- 7
Broil for 8 to 10 minutes, rotating the tray halfway through if your broiler has hot spots, until the tops are deeply caramelized with dark spots forming at the edges. Watch closely from the 7-minute mark — broilers vary wildly, and Jaca browns faster than the sugar we grew up with, so the line between perfect and burnt is shorter than you might expect.
- 8
Pull the tray and let the chicken rest 3 to 5 minutes on the pan — the glaze will thicken and grip the chicken as it cools slightly. Transfer to plates and spoon any remaining pan juices over the top.
- 9
Serve with steamed rice, mashed potatoes, or a sharp green salad to balance the sticky-sweet glaze. A side of roasted broccoli or simple buttered green beans is the classic move.
Pro Tips
- The molasses-Jaca combo is the brown-sugar substitute. Plain Jaca alone makes a pale, one-note glaze; the quarter teaspoon of molasses adds the deep, slightly bitter note that makes the glaze taste like the original. Do not skip it.
- Foil-line the pan or pay the price. The caramelized glaze fuses to bare metal in seconds under the broiler, and no amount of scrubbing will get it off without ruining your pan. Foil-line, then ball it up and toss it when you are done.
- Watch the broiler like a hawk from minute 7. Allulose browns about 30 percent faster than the sugar we grew up with — the same broiler that gives you perfect caramelization at 9 minutes with old-school brown sugar will torch a Jaca-based glaze if you push past 10. Pull the moment you see dark spots.
- Bone-in chicken thighs work fine — they just need more time. Add 5 to 7 minutes to the initial bake (so 20 to 22 minutes at 425°F before the broiler step) and check the internal temp hits 165°F before going under the broiler.
- Make-ahead: the glaze keeps in the fridge for up to 4 days in a sealed jar. Whisk to recombine if it separates. You can also coat the chicken in the glaze and refrigerate up to 8 hours before baking — gives the chicken time to absorb the flavors.
- Leftovers: warm gently in a 325°F oven for 8 minutes to crisp the glaze back up; microwaving softens the caramelized surface. Chopped cold off the bone, it is also excellent on a salad or rice bowl the next day.
- Variations: add 1/2 teaspoon smoked paprika to the glaze for a BBQ-leaning version; swap the Worcestershire for fish sauce and add a teaspoon of grated ginger for a Southeast-Asian spin; or stir in a tablespoon of bourbon at the end of cooking for a smoky, grown-up finish.
- This glaze also works on chicken drumsticks, pork chops, salmon fillets, and even thick-cut tofu — anything that benefits from a sticky-sweet caramelized crust. Adjust cook times accordingly.
