An Old Favorite: Green Chili Chicken

Years ago (eons?) I happened across this recipe on a Foster Farms whole chicken wrapper.  Before ripping open the plastic wrapper to cut up the chicken, I'd often give the printed recipe on each package a quick scan to see if it sounded good.  Not only did this one catch my eye, but it's stayed a family favorite all this time.  Now I make it with chicken thighs, instead of a whole chicken.
Times have changed!

Green Chili Chicken from Foster Farms

8 boneless skinless chicken thighs  (smallish)                        
2 tsp. chili powder                                                                
1/2-1/4 tsp. red pepper (according to taste)                         
1 tsp. ground cumin                                                              
1 tsp. salt                                                                             
1 Tbsp. oil                                                                          
2 garlic cloves pressed
1/2 C. finely diced onion
1 4oz. can green chilis
1 C. chicken broth
2 Tbsp. flour
2 Tbsp. water
1/2 C. sour cream

Rub outside of chicken with first 4 ingredients--mixed.  Let sit for 20 minutes, if you wish.  Heat oil in dutch oven, brown chicken on both sides.  Add garlic, onion, chilies and broth.
Cover and simmer 35 - 45 minutes.
Remove chicken to platter, draining juices back into pan.  Skim fat from sauce in pan.  Blend together flour and water, stir into sauce.  Cook, stirring constantly until thickened.  Remove from heat.
Stir in sour cream.
Serve with rice.
