Creating Slow Cooker Chicken Stew is a breeze if you follow these simple steps:

1. Prepare Ingredients: Begin by washing and chopping all vegetables. Ensure the chicken is cut into bite-sized pieces if using breasts.
2. Sauté Aromatics: In a skillet over medium heat, add olive oil. Sauté the onions and garlic until softened, about 3-4 minutes.
3. Combine Ingredients: In the slow cooker, layer the chicken, sautéed onions and garlic, carrots, celery, potatoes, and frozen peas.
4. Add Seasonings: Sprinkle thyme, oregano, salt, and pepper over the mixture. Pour in the chicken broth.
5. Stir Gently: Mix everything together gently, ensuring that the chicken is submerged in the broth.
6. Cook: Cover and set the slow cooker to low for 6-8 hours or on high for 3-4 hours.
7. Thicken Stew: About 30 minutes before serving, mix cornstarch with a small amount of water to create a slurry. Stir it into the stew to thicken.
8. Check for Doneness: Ensure the chicken is cooked through and the vegetables are tender. Adjust seasoning if necessary.
9. Garnish: Before serving, sprinkle chopped parsley on top for added freshness.
10. Serve: Ladle the stew into bowls and enjoy while hot.
