- Combine garam masala, garlic salt, and pepper on a dinner plate. Spoon flour on to second dinner plate. Coat each chicken breast with mixture and then dredge well in flour.
- Heat oil in large skillet. Add chicken and cook over medium-high heat until chicken is golden brown on both sides (approx. 3-4 minutes per side). Cook chicken in two batches if necessary so as not to crowd the pan.
- Place chicken in large slow cooker and add remaining ingredients except for fresh thyme. Cover slow cooker and cook on high for 4 hours or on low for 8 hours.
- Sprinkle with fresh thyme before serving, if desired.
