Begin by finely dicing the yellow onion and chopping the lemongrass. Mince the garlic and grate the ginger. Having everything ready will make the cooking process seamless.
In a bowl, mix together the diced onion, minced garlic, grated ginger, chopped lemongrass, and Thai red curry paste. This will form the flavorful base of your curry.
In your crockpot, add the mixture from Step 2. Pour in the full-fat coconut milk, followed by the fish sauce and honey. Stir gently to combine all the ingredients.
Next, add the diced chicken to the crockpot. Make sure the chicken is evenly coated with the curry mixture to absorb all the delicious flavors.
Add the roughly chopped broccoli rabe to the crockpot. This will infuse the dish with vibrant color and nutrition.
Cover the crockpot and cook on low for 6-8 hours or high for 3-4 hours. The chicken should be tender and the flavors well blended.
Once cooked, stir in the chopped basil or cilantro just before serving to add a fresh burst of flavor.
Serve your delicious curry over steamed rice and top with pomegranate arils and chopped peanuts for an extra crunch.
