  • 2 lb. boneless skinless chicken thighs
  • 1 cup uncooked quinoa rinsed well
  • 24 oz jar of marinara sauce I like to use a brand that doesn’t include any added sugar in the ingredient list
  • 4 cups chicken broth
  • 1 cup water
  • 2 red bell peppers seeded and chopped
  • 3 large carrots peeled and sliced into rounds
  • 1 medium yellow onion diced
  • 1 14.5 ounce can petite-diced tomatoes, NOT drained
  • Salt and pepper to taste

Optional Toppings:


  • Combine all ingredients in a large slow cooker.
  • Cover, and cook on “low” for about 7-8 hours, or on high for 3-4 hours.
  • Remove the chicken from the slow cooker. Shred or dice the meat, return it to the pot, and season with salt and pepper.
  • Garnish with cheese and parsley and serve.


  • Want to Make it Vegetarian? Omit the chicken and replace the meat with 2 cans of drained and rinsed cannellini beans, garbanzo beans, or kidney beans. You can substitute vegetable broth for the chicken broth, too!
  • Cooking for Just Two? You can easily cut the recipe in half, which will give you 4 servings of soup. It freezes nicely or keeps in the refrigerator for about a week, so you can enjoy the extra servings at a later date (with no grocery shopping or prep work necessary)!
  • Want to Prep Ahead? You can make this a slow cooker freezer meal by dumping all of the raw ingredients into a zip-top bag and freezing until ready to use. Before cooking, thaw the bag in the refrigerator overnight and then cook the next day as instructed. Alternatively, you can prepare a big batch of this soup over the weekend and store the extra cooked soup in your freezer for up to 3 months or in your refrigerator for about a week.
