Pour the whisked peanut satay mixture evenly over the raw chicken thighs in the slow cooker, making sure all of the chicken is coated. Use a spoon to nudge the sauce around so it covers any exposed spots.
Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or on HIGH for 2 1/2 to 3 hours, until the chicken thighs are very tender and easily pull apart with a fork.
Once cooked, use two forks to gently shred or chunk the chicken thighs right in the slow cooker, stirring them into the peanut sauce so everything is well coated. Taste the sauce and add a little extra lime juice or a splash of soy sauce if you’d like more brightness or saltiness.
Serve the peanut satay chicken hot over cooked rice or noodles, spooning plenty of sauce over each portion. Garnish with chopped peanuts, sliced green onions, cilantro, and lime wedges if your family enjoys them.
For picky eaters, reduce the sriracha to 1 tablespoon or skip it entirely, then let adults add extra heat at the table with more sriracha or red pepper flakes. If there’s a peanut allergy in the house, you can swap the peanut butter for creamy almond butter or sunflower seed butter; just taste and adjust the brown sugar and lime so the sauce stays balanced. For a veggie boost, tuck 2 cups of sliced bell peppers or matchstick carrots around the chicken before you whisk and pour the sauce over the top; they’ll soften and soak up the flavor as everything cooks. If you prefer chicken breasts, use the same amount as the thighs but check for doneness a little earlier so they don’t dry out. To make it a bit lighter, you can use light coconut milk, though the sauce will be slightly thinner. Leftovers keep well in the fridge for up to 3 days and reheat nicely on the stove with a splash of water or coconut milk to loosen the sauce, making an easy next-day lunch that tastes just as comforting as the first night.
