Creating Autumn Chicken Stew is straightforward when you follow these steps:

1. Prepare Ingredients: Chop all vegetables and set aside.
2. Sear Chicken: In a large pot, heat olive oil over medium heat. Add the chicken thighs, seasoning with salt and pepper. Sear until browned on both sides (about 5-7 minutes). Remove chicken and set aside.
3. Sauté Vegetables: In the same pot, add onions and garlic. Sauté for 2-3 minutes until fragrant. Add carrots, celery, and potatoes. Cook for an additional 5 minutes.
4. Add Seasonings: Stir in thyme, rosemary, and the bay leaf. Mix well to coat the vegetables.
5. Add Broth: Pour in chicken broth and bring to a boil. Scrape the bottom of the pot to release any browned bits.
6. Return Chicken: Add the seared chicken back to the pot. Reduce heat to low and cover, letting it simmer for 45 minutes.
7. Adjust Seasoning: After 45 minutes, taste the stew and adjust seasoning with salt, pepper, and lemon juice as desired.
8. Shred Chicken: Remove the chicken thighs and shred them with two forks. Return the shredded chicken to the stew and mix well.
9. Final Simmer: Allow the stew to simmer for an additional 10-15 minutes for flavors to meld.
10. Serve: Ladle the stew into bowls and garnish with fresh parsley, if desired.

These simple steps will guide you in crafting an incredible Autumn Chicken Stew that will warm both your kitchen and your heart.
