- Butter: Adds richness and helps the seasonings adhere to the chicken, resulting in a moist and flavorful meat.
- Salt and pepper: Essential for enhancing all the natural flavors and ensuring the chicken is well-seasoned throughout.
- Garlic: Provides a savory, aromatic depth that infuses the chicken and vegetables with a warm, comforting flavor.
- Oregano or other dried herbs: Lend an earthy, herbal note that complements the chicken and brightens the overall taste.
- Carrots: Offer a subtle sweetness and become tender as they cook, soaking up the delicious juices from the chicken.
- Celery: Adds a mild, aromatic flavor and a pleasant texture to the vegetable mix at the bottom of the slow cooker.
- Onion: Brings a gentle sweetness and savory backbone, enriching the broth and overall flavor of the dish.

Step-by-Step Instructions
Prep the Chicken
Pat the chicken dry with paper towels. Removing excess moisture helps the seasoning stick and ensures a juicy result.
Make the Garlic Herb Butter
In a small bowl, mix the softened butter with salt, pepper, minced garlic, and dried herbs of choice (oregano, thyme or rosemary). Rub this flavorful paste all over the chicken, including under the skin and inside the cavity, if possible, for extra flavor.



Layer the Vegetables
Place the carrots, celery, and onion at the bottom of your slow cooker. This not only flavors the chicken but also keeps it elevated, allowing heat to circulate for even cooking.
Add the Chicken
Set the seasoned chicken breast-side up on top of the vegetables.


Slow Cook to Perfection
Cover and cook on low for 6–8 hours or 4 hours on high. The chicken should reach an internal temperature of at least 165°F in the thickest part of the thigh. The long, slow cook time ensures incredibly tender meat.
Add Lemon Juice
About one hour before serving, pour the lemon juice over the chicken. This brightens the flavors and adds a subtle tang to your gravy. Lemon juice can also be simply added to the broth before making a gravy.
Serve
Carefully transfer the chicken to a cutting board and carve. Skim any fat from the juices in the slow cooker and spoon some of the flavorful broth over the chicken when serving.
