Slow Cooker Chicken and Rice

There’s something especially comforting about the smell of onions slowly caramelizing and a cozy chicken dinner cooking away in the slow cooker. This old fashioned slow cooker French onion chicken and rice brings together those familiar flavors in the easiest way.

Tender chicken cooks low and slow in a creamy onion-rich sauce, soaking up all that savory flavor while the rice turns soft and fluffy underneath. Finished with melted Swiss cheese, it feels like a cross between French onion soup and a classic chicken casserole.

It reminds me of the kind of supper Grandma would make when she wanted something hearty, comforting, and sure to please everyone at the table.

How to Make Old Fashioned Slow Cooker French Onion Chicken and Rice

Step 1: In a large skillet over medium heat, add the oil, butter, and sliced onions. Cook until the onions are soft and just beginning to brown, stirring occasionally. Remove from the skillet and set aside.

Step 2: Season the chicken breasts with 1 teaspoon garlic powder, paprika, and ½ teaspoon black pepper.

Step 3: In the same skillet used for the onions, sear the chicken breasts just until lightly browned on both sides. Do not cook through. Remove and set aside.

Step 4: In a large bowl, combine the cream of chicken soup, chicken broth, 1 teaspoon garlic powder, ½ teaspoon black pepper, uncooked white rice, and dry onion soup mix. Stir well.

Step 5: Pour the rice mixture into the slow cooker, spreading it evenly. Place the seared chicken breasts on top, then layer the caramelized onions over the chicken.

Step 6: Cover and cook on High for 3 hours or on Low for 5 hours, until the chicken is cooked through and the rice is tender.

Step 7: Place the Swiss cheese slices over the chicken, cover, and let sit for about 5 minutes until the cheese melts. Garnish with fresh parsley and serve warm.
