Step 1

Lightly coat a 5-quart or larger slow cooker with nonstick spray. Add the rice, carrots, shallot, and Dijon mustard, and stir to combine. Arrange the chicken breasts on top, then sprinkle with the garlic powder, thyme, salt, and pepper. Pour in the chicken broth. Cover and cook on HIGH for 1 1/2 to 2 1/2 hours, until the chicken is cooked through.

Step 2

Remove the chicken into a plate and cover to keep warm. Stir the rice, vegetables, and broth, then re-cover and continue cooking on high until the rice is tender, about 1 additional hour.*

Step 3

Uncover and stir in the peas and Greek yogurt. Dice the chicken and stir it in with 1/4 cup cheddar cheese. Sprinkle the remaining cheese over the top, then re-cover and cook for a few additional minutes on high until the cheese is melted. Serve warm, sprinkled with fresh parsley as desired.
