Add tomato paste, coconut milk, garlic, ginger, cumin, turmeric, garam marsala, and salt to a bowl. Mix until incorporated, then add to crockpot/slow cooker.
Add cinnamon stick, bay leaves, chicken, and onions to crockpot/slow cooker.
Cover and cook on low for 8 hours (or high for 4 hours), until chicken is tender and has reached an internal temperature of 165 degrees F.
Remove and discard the cinnamon stick and bay leaves. Shred chicken (if desired) and serve topped with fresh cilantro, over a bed of cauliflower rice.
Substituting chicken breasts for the specified thighs alters the final moisture level significantly because lean white meat dries out rapidly during extended simmering periods exceeding six hours. Chicken thighs contain higher amounts of connective tissue and fat, which render slowly over a long cooking window to keep the meat tender while enriching the surrounding sauce. Whisking the tomato paste directly into the full-fat coconut milk before heating creates a uniform emulsion that prevents the coconut solids from separating under prolonged heat. Ground spices such as cumin and turmeric contain fat-soluble aromatic compounds that bond effectively with the lipids present in coconut milk, resulting in a cohesive flavor profile rather than a raw, powdery finish.
Thermal Management and Liquid Stability
Maintaining a stable cooking temperature inside the slow cooker ensures the poultry reaches the mandatory internal threshold of 165 degrees Fahrenheit without overcooking the surrounding proteins. Full-fat canned coconut milk handles extended thermal exposure better than light varieties, though keeping the lid sealed tightly prevents excessive evaporation and surface curdling. Whole aromatics like the cinnamon stick and bay leaves release their volatile oils gradually over the eight-hour low setting, imparting subtle woody notes that ground spices cannot replicate on their own.
Post-Simmer Finishing Techniques
Discarding the whole cinnamon stick and bay leaves prior to service prevents accidental bitterness from lingering in the sauce. Shredding the meat directly inside the cooking vessel allows the protein strands to reabsorb the seasoned liquid, yielding a more cohesive texture that clings to cauliflower rice or grain bases. Leftovers should be cooled rapidly within two hours before transferring them to an airtight container for storage in the refrigerator for up to four days.
