All the bright, tangy flavour of kimchi paired with the rich, buttery-ness of roast chicken - these kimchi butter chicken thighs are to die for, especially when paired with roasted garlic & sesame mashed potatoes.
Preheat the oven to 200 C. Slice off the top of the garlic, drizzle with olive oil and wrap with foil, before leaving to roast for 45 minutes or until soft and jammy.
Blend together the kimchi, spring onions, and garlic. Mix well with softened butter, gochugaru, and salt. Don’t worry if it looks like it's separating - once it’s in the oven it’ll melt nicely
Separate the skin from the chicken, and push the butter under the skin. Season the skin with salt and pepper
Sear the chicken skin side down in a skillet with a splash of oil over medium/high heat. Leave undisturbed for at least 5 minutes or until golden, then flip.
Add some quartered onions, cut side down, in and around the chicken, along with some extra kimchi butter. Add a splash of water to help everything cook.
Pop into the oven to finish cooking, around 15-20 minutes, until the thickest part of the chicken reaches 73 C.
Meanwhile, boil the potatoes until fork tender. Drain, then mash the potatoes (either with a potato masher, ricer, or immersion blender) with butter, roasted garlic, and milk. Season with salt and pepper, sesame oil, and chives.
Smooth the potatoes over a platter, then serve the chicken on top. Don't forget to drizzle over any extra sauce, and finish with spring onions and more chilli.
