Ingredients
  

  • 2 to 2.5 pounds boneless, skinless chicken breasts
  • 1 cup basil pesto (homemade or store-bought)
  • 1/4 cup low-sodium chicken broth (or water)
  • 3 to 4 cloves garlic, minced
  • 1/2 teaspoon kosher salt (adjust to taste)
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon Italian seasoning (optional)
  • 1 tablespoon lemon juice (optional, for brightness)
  • 1/4 cup grated Parmesan cheese, plus more for serving
  • 2 tablespoons unsalted butter or 1 tablespoon olive oil (optional, for extra richness)
  • Fresh basil, chopped, for garnish
  • Cherry tomatoes or sun-dried tomatoes (optional add-in)
  • Mozzarella slices or shredded mozzarella (optional, for topping)

Method
 

  1. Prep the slow cooker: Lightly grease the crock with a bit of oil or cooking spray to prevent sticking and make cleanup easier.
  2. Season the chicken: Pat the chicken breasts dry. Sprinkle both sides with salt, pepper, and Italian seasoning. This helps the flavors sink in and keeps the meat juicy.
  3. Mix the sauce: In a bowl, stir together the pesto, chicken broth, minced garlic, lemon juice (if using), and Parmesan. If you want a richer sauce, add butter or olive oil.
  4. Assemble: Place the chicken in the slow cooker in a single layer. Pour the pesto mixture over the top, making sure each breast is well coated. Add cherry tomatoes or sun-dried tomatoes if you like.
  5. Cook: Cover and cook on Low for 3 to 4 hours or High for 1.5 to 2.5 hours, depending on thickness. Chicken is done when it reaches 165°F in the thickest part and is tender but not falling apart.
  6. Optional cheesy finish: In the last 10 minutes, top each breast with mozzarella and cover to melt.
  7. Rest and serve: Let the chicken rest in the sauce for 5 minutes. Spoon extra pesto sauce over the top and garnish with fresh basil and more Parmesan.
  8. Serve with: Pasta, gnocchi, rice, quinoa, mashed potatoes, or roasted veggies. Garlic bread is excellent for soaking up the sauce.
