Place the diced onions, minced garlic, and ginger paste in the bottom of the slow cooker basin.
Arrange the cubed chicken breast in an even layer over the aromatic base.
In a small mixing bowl, whisk together the korma curry paste, chicken broth, and almond flour until smooth.
Pour the curry paste mixture over the chicken, ensuring all pieces are lightly coated.
Cover and cook on the low setting for 6 hours until the chicken reaches an internal temperature of 165 degrees Fahrenheit.
Stir in the coconut milk and Greek yogurt gently to incorporate into the sauce.
Cover and cook for an additional 20 minutes to allow the sauce to thicken and flavors to meld.
Season with salt and pepper to taste and garnish with fresh cilantro before serving.
