Chicken and Corn Chowder with Sweet Pot

Chicken and Corn Chowder with Sweet Potatoesadapted from Cook's Countryserves 6-8

3 cups whole milk (I didn't have whole milk so I used 2 cups 1% and 1 cup cream)
1 cup yellow corn muffin mix (Jiffy brand was recommended in the original recipe but I used a Betty Crocker mix and it worked just fine)
2 T. butter
1 onion, chopped fine
3 garlic cloves, minced
1/2 tsp. ground cumin
1/2 tsp. dried oregano
2 quarts low-sodium chicken broth
1 1/2 pounds boneless, skinless chicken breasts, cut into 1/2 " cubes
2 sweet potatoes (about 1 1/2 pounds), peeled and cut into 1/2" pieces
1 cup shredded Monterey Jack Cheese
3 cups frozen corn (not thawed)
1/2 cup chopped fresh parsley
salt and pepper, to taste

Mix milk and muffin mix in bowl until well combined. Meanwhile, heat butter in large pot over medium heat until foaming. Add onion and cook until softened, about 8 minutes. Stir in garlic, cumin and oregano and cook until fragrant, about 30 seconds. Add broth, chicken and sweet potatoes. Bring to boil, reduce heat, and simmer until sweet potatoes are just tender, about 8 minutes.

Stir in milk and muffin mixture and simmer until soup thickens, about 10 minutes.Add cheese and corn and cook until cheese begins to melt, about 2 minutes. Stir in parsley and season with salt and pepper. Serve.
