Slow Cooker Tuscan Chicken Ingredients

See the recipe card below for a complete list of ingredients and measurements.

• Boneless, skinless chicken breasts – Use 2 pounds of chicken breasts for this recipe. They become incredibly tender after slow cooking and absorb all the delicious flavors from the sauce.
• Salt and black pepper – Basic seasoning that enhances the natural flavor of the chicken. Don’t skip this step as it builds the foundation of taste.
• Garlic powder – Adds a warm, savory depth to the chicken. Combined with the fresh garlic in the sauce, it creates layers of flavor.
• Italian seasoning – A blend of herbs like oregano, basil, and thyme that gives this dish its signature Tuscan character. This is what makes the flavor profile truly Italian.
• Small onion – Finely diced onion adds sweetness and depth to the sauce as it cooks down. It creates a flavorful base for the cream sauce.
• Fresh garlic – Minced garlic cloves provide a robust, aromatic quality that’s essential to this recipe. Fresh garlic is always better than jarred for this dish.
• Sun-dried tomatoes – These concentrated, tangy tomatoes add a pop of flavor and beautiful color. Make sure to drain and chop them before adding to the slow cooker.
• Chicken broth – Provides the liquid base for the sauce and keeps the chicken moist during cooking. Use a good-quality broth for the best flavor.
• Heavy cream – Creates the rich, luxurious cream sauce that coats the chicken perfectly. This is what makes the dish so indulgent and satisfying.
• Cream cheese – Adds extra creaminess and helps thicken the sauce beautifully. Make sure it’s softened and cubed for easy mixing.
• Grated Parmesan cheese – Brings a nutty, salty flavor that’s classic in Italian cooking. Freshly grated Parmesan works best for melting smoothly into the sauce.
• Fresh spinach – Added at the end so it wilts perfectly without overcooking. Spinach adds a pop of color and nutritional value to the dish.
• Cornstarch and cold water – This slurry thickens the sauce to the perfect consistency. Mix them together before adding to avoid lumps.
• Fresh basil or parsley – A finishing touch that adds brightness and freshness. Either herb works beautifully as a garnish.

Substitutions and Additions

• Chicken thighs instead of breasts – Boneless, skinless chicken thighs work perfectly and stay even more tender in the slow cooker.
• Half-and-half for heavy cream – You can use half-and-half for a lighter sauce, though it won’t be quite as rich and creamy.
• Kale instead of spinach – Swap fresh spinach for chopped kale if you prefer a heartier green with more texture.
• Red pepper flakes – Add a pinch of red pepper flakes to the sauce for a subtle spicy kick.
• Mushrooms – Sliced mushrooms can be added with the onions for an earthy flavor and extra vegetables.
• White wine – Replace some of the chicken broth with white wine for added depth and acidity.

How to Make Slow Cooker Tuscan Chicken (step-by-step directions)

STEP 1. Start by seasoning the chicken breasts with salt, black pepper, garlic powder, and Italian seasoning on all sides. Place the seasoned chicken in the bottom of your slow cooker in a single layer. Scatter the diced onion, minced garlic, and chopped sun-dried tomatoes over the top of the chicken. Pour the chicken broth over everything, then add the cubed cream cheese around the chicken pieces. (Photo 1)

STEP 2. Cover the slow cooker and cook on Low for 4 to 6 hours or on High for 2 to 3 hours, until the chicken is tender and cooked through. The chicken should reach an internal temperature of 165°F. Remove the chicken from the slow cooker and set it aside. If you prefer, you can shred or slice the chicken at this point. Whisk the cream cheese into the broth mixture in the slow cooker until it’s completely smooth and no lumps remain.

STEP 3. Stir in the heavy cream and grated Parmesan cheese, whisking until well combined. Mix the cornstarch with cold water in a small bowl to create a slurry, then stir it into the sauce. Add the fresh spinach and increase the heat to High for 10 to 15 minutes until the sauce has thickened and the spinach is wilted. (Photo 2)

STEP 4. Return the chicken to the slow cooker, spooning the creamy sauce over the top. Garnish with fresh basil or parsley before serving.

Recipe Tips

• Slice chicken for better sauce coverage – After cooking, slice the chicken breasts into medallions so each piece gets coated in the creamy sauce when served.
• Use oil-packed sun-dried tomatoes – Sun-dried tomatoes packed in oil add extra richness to the dish compared to the dry-packed variety.
• Don’t add spinach too early – Wait until the last 10 to 15 minutes to add the spinach so it doesn’t overcook and become mushy.
• Adjust thickness – If your sauce is too thick, add a splash of chicken broth or milk. If it’s too thin, let it cook on High uncovered for a few extra minutes.
• Fresh Parmesan is best – Use freshly grated Parmesan cheese rather than pre-grated for better melting and richer flavor.

Storing Tips

• Storage: Store leftover Slow Cooker Tuscan Chicken in an airtight container in the refrigerator for up to 4 days. The sauce will thicken as it cools but will loosen up when reheated.
• Refrigerator: Keep the chicken and sauce together in an airtight container for best results. Make sure it’s cooled completely before refrigerating to maintain food safety.
• Freezing: You can freeze this dish for up to 2 months, but it’s best to freeze it without the spinach for optimal texture. Add fresh spinach when you reheat the dish.
• Reheating: Warm the chicken gently on the stovetop over medium-low heat, stirring occasionally. Add a splash of chicken broth or heavy cream if the sauce needs thinning. You can also reheat in the microwave in 1-minute intervals, stirring between each.

Serving Suggestions

This creamy Slow Cooker Tuscan Chicken pairs beautifully with so many sides. Serve it over Crockpot Spanish Rice for a flavorful base, or spoon it over pasta for a classic Italian-inspired meal. Baked Ziti with Alfredo Sauce makes an excellent side when you want to go all-in on comfort food.

If you want to make it a complete one-dish meal, add some cubed potatoes to the slow cooker during the last hour of cooking.
