Ingredients Method

Ingredients
  

  • 2 pounds boneless, skinless chicken breasts (or thighs)
  • 1 tablespoon olive oil (optional, for searing)
  • 1 teaspoon kosher salt, plus more to taste
  • 1/2 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon Italian seasoning
  • 4 cloves garlic, minced (or 1 1/2 teaspoons garlic paste)
  • 1/2 cup sundried tomatoes, drained and sliced (oil-packed is best)
  • 1 cup low-sodium chicken broth
  • 1 tablespoon cornstarch (optional, for thickening)
  • 1 cup heavy cream (or half-and-half for a lighter version)
  • 1/2 cup grated Parmesan cheese
  • 3 cups fresh baby spinach
  • 1 tablespoon lemon juice (optional, to brighten)
  • Fresh basil, chopped (optional, for garnish)

Method
 

  1. Season the chicken: Pat chicken dry. Sprinkle with salt, pepper, garlic powder, onion powder, and Italian seasoning. Rub to coat evenly.
  2. Optional sear: Heat olive oil in a skillet over medium-high heat. Sear chicken 1–2 minutes per side until lightly golden. This step adds flavor but isn’t required.
  3. Layer in the slow cooker: Add chicken to the crockpot. Scatter minced garlic and sundried tomatoes over the top. Pour in the chicken broth.
  4. Cook low and slow: Cover and cook on Low for 3.5–4.5 hours or on High for 2–3 hours, until chicken is tender and reaches 165°F internally.
  5. Thicken the sauce (optional): Whisk cornstarch with 1 tablespoon cold water. Stir the slurry into the cooking liquid and cook 10–15 minutes until slightly thickened.
  6. Add the cream and cheese: Stir in heavy cream and Parmesan. Cover and cook another 10 minutes to melt and combine.
  7. Finish with greens: Add spinach, stirring until just wilted, 2–3 minutes. If using, add lemon juice to brighten the flavors.
  8. Taste and serve: Adjust seasoning with salt and pepper. Serve whole or sliced chicken with plenty of sauce over pasta, rice, or potatoes. Garnish with fresh basil if you like.
