Ingredients

• 8 bone-in, skin-on chicken thighs
• 6 tablespoons butter
• 8 cloves garlic, minced
• 3 large yellow onions, sliced
• 1 cup chicken broth
• 1/2 cup dry white wine
• 2 teaspoons dried thyme
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 2 bay leaves
• 2 tablespoons olive oil

Instructions

1. Heat olive oil in a large skillet over medium-high heat. Season chicken thighs with salt and pepper, then brown skin-side down for 4 minutes per side. Transfer to slow cooker.
2. In the same skillet, melt 3 tablespoons butter over medium heat. Add sliced onions and cook for 8 to 10 minutes, stirring occasionally, until golden and caramelized. Transfer to slow cooker.
3. Reduce heat to medium, add remaining 3 tablespoons butter and minced garlic to the skillet. Cook for 1 minute until fragrant, then add wine and broth. Scrape up browned bits from the pan.
4. Pour garlic butter sauce over chicken and onions in slow cooker. Add thyme and bay leaves.
5. Cover and cook on low for 6 to 7 hours or on high for 3 to 4 hours, until chicken is tender and cooked through.
6. Remove bay leaves before serving.

Practical Tips

Tip 1: Browning the chicken before slow cooking creates a flavorful crust and helps seal in juices, making the final dish more savory and complex.

Tip 2: For extra flavor, add a squeeze of fresh lemon juice just before serving to brighten the rich garlic butter sauce.

Tip 3: If you prefer a thicker sauce, mix 2 tablespoons cornstarch with 3 tablespoons cold water and stir into the slow cooker during the last 30 minutes of cooking.

How to Store It

Store leftovers in an airtight container in the refrigerator for up to 4 days. The chicken and sauce reheat beautifully on the stovetop over medium heat or in the microwave. You can also freeze the entire dish for up to 3 months, though the chicken skin may lose some texture after thawing.

Common Questions

Can I use chicken breasts instead of thighs? While you can substitute chicken breasts, thighs are recommended because they stay moist and tender during the long cooking process. Breasts tend to dry out more easily.

Is the wine necessary? The wine adds depth and acidity to balance the richness of the butter and garlic. You can substitute it with additional chicken broth if needed, though the flavor will be slightly different.

Can I cook this on high instead of low? Yes, you can cook on high for 3 to 4 hours. However, cooking on low for 6 to 7 hours produces more tender chicken and better developed flavors.
