Buttermilk-marinated chicken thighs baked until the skin shatters, then spooned with a blueberry sauce made from apple cider vinegar, honey, and thawed frozen blueberries. This is not fusion cooking for the sake of being clever. The acid in the blueberry sauce does for chicken what cranberry sauce does for turkey, and it does it better. The buttermilk marinade with salt and black pepper tenderizes the meat while the oven handles the crunch. We keep making this on repeat for exactly that reason.
Marinating the chicken thighs in buttermilk for at least 30 minutes breaks down the proteins on the surface, which is why the skin crisps so hard at 400 degrees F (200 degrees C). The blueberry sauce simmers separately with apple cider vinegar, honey, and water until it reduces to a syrupy consistency that clings to each thigh rather than pooling on the plate.
Tips for Crispy Chicken with Blueberry Sauce
Do Not Skip the Buttermilk Soak
Marinate the chicken thighs in buttermilk seasoned with salt and black pepper for a minimum of 30 minutes, or up to overnight. The lactic acid in buttermilk tenderizes the meat and helps the skin render fat more efficiently during baking. 
Pat the thighs dry with paper towels after removing them from the buttermilk. Wet skin steams instead of crisps. Season the outside with a final pinch of salt before placing them on the baking sheet.
Reduce the Sauce Until It Coats a Spoon
Combine thawed frozen blueberries, apple cider vinegar, honey, water, and salt in a saucepan. Simmer over medium heat until the blueberries break down and the sauce thickens enough to coat the back of a spoon.
Taste the sauce before spooning it over the chicken. If it is too tart, add another tablespoon of honey. If too sweet, a splash more apple cider vinegar sharpens it. The balance should lean slightly tart since the chicken is already rich.

Frequently Asked Questions
Can I use fresh blueberries instead of frozen?
Yes. Fresh blueberries take a few extra minutes to break down in the sauce. Frozen blueberries thaw and burst faster, which is why the recipe calls for them, but either version produces a good sauce.
Can I use chicken breasts instead?
You can, but thighs produce crispier skin and juicier meat. Breasts dry out faster at 400 degrees F (200 degrees C) and have less fat to render. If using breasts, reduce the bake time by about five minutes and check for doneness with a thermometer.
How long should I marinate the chicken?
A minimum of 30 minutes makes a noticeable difference in tenderness. Overnight is ideal if you have the time. Beyond 24 hours, the buttermilk starts to break down the meat too much and the texture turns mushy.
The comparison to cranberry sauce got me to try this and it was SHOCKINGLY good. Tart, sweet, acid, warm against rich meat. Apple cider vinegar in the blueberry reduction was the bit I’d have skipped reading the recipe. Now I wouldn’t leave it out.
I marinated overnight in buttermilk and the skin made the difference. Pulled the thighs onto a paper towel for ten minutes before they went in the oven and the skin shattered the way the writeup promised. Blueberry sauce reduced thicker than I expected, I added a splash of water at the end to bring it back.
buttermilk skin trick keeps paying off.
Frozen blueberries thawed worked exactly as written. I had a bag in the freezer from last summer’s farmers market haul and the sauce came together over a quick simmer. Honey and cider vinegar balanced the natural sweetness of the berries, didn’t need any extra sugar.
