| Basil pesto (store-bought or homemade) | 1/2 cup |
| Cherry tomatoes, halved | 1 cup |
| Fresh mozzarella, sliced | 4 oz |
| Chicken broth | 1/4 cup |
| Garlic cloves, minced | 3 cloves |

Step by Step Instructions
Step 1: Season the chicken
Season the chicken breasts with salt and pepper on both sides.
Step 2: Add to the crockpot
Place the chicken in the slow cooker. Add the minced garlic and pour the chicken broth around the edges.
Step 3: Add pesto and tomatoes
Spread the basil pesto evenly over the top of each chicken breast. Scatter the cherry tomatoes around and on top.
Step 4: Cook
Cover and cook on LOW for 4 to 5 hours or on HIGH for 2 to 2.5 hours.
Step 5: Add mozzarella
In the last 15 minutes of cooking, place fresh mozzarella slices on top of each chicken breast. Replace the lid and cook until the cheese melts.
Step 6: Serve
Serve whole or shred the chicken and toss with the pesto sauce. Garnish with fresh basil leaves.
Tips and Tricks
- Use a high-quality store-bought pesto or make a fresh basil pesto for the best flavor
- Do not over-sauce a generous spread of pesto on each breast is sufficient since the chicken releases its own juices
- Add the mozzarella in the last 15 minutes only to prevent it from becoming rubbery or completely dissolving into the sauce
- A drizzle of good olive oil just before serving brightens all the flavors significantly
- Balsamic glaze drizzled on top at the end adds a beautiful sweet-acidic contrast to the pesto
Serving Suggestions
- Over pasta tossed with olive oil and extra pesto
- On a bed of arugula dressed with lemon and olive oil
- With roasted zucchini or bell peppers for a full Italian-inspired plate
- Stuffed into a ciabatta roll with extra mozzarella for an incredible sandwich
- Over orzo pasta with cherry tomatoes and extra parmesan
Mistakes to Avoid
- Adding the mozzarella at the start : it will completely melt and dissolve into the sauce rather than sitting beautifully on top of the chicken. Always add it in the last 15 minutes.
- Using low-quality pesto : the pesto is the primary flavor driver of this recipe. Use a quality pesto with real basil, olive oil, and pine nuts for the best result.
- Overcooking the chicken : pesto chicken can dry out quickly if overcooked. Check at the 4-hour mark on LOW.
- Adding too much broth : you only need a small amount to prevent sticking. Too much liquid dilutes the pesto flavor significantly.
- Skipping the fresh basil garnish : it adds a bright, fresh contrast to the richness of the melted pesto and cheese.

FAQ
Can I use homemade pesto instead of store-bought?
Absolutely. Homemade fresh basil pesto produces the most vibrant flavor. If using homemade pesto, add it about 30 minutes before the end of cooking to preserve the fresh herb flavor.
Can I make this recipe dairy-free?
Yes. Simply omit the mozzarella or use a dairy-free cheese alternative. The pesto sauce itself is still incredibly flavorful without the cheese.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or on the stovetop with a splash of chicken broth.
Can I use chicken thighs?
Yes. Boneless chicken thighs work well and stay juicier than breasts. Use the same quantity and cook time.
What type of pesto works best in this recipe?
Classic basil pesto is ideal, but sun-dried tomato pesto, roasted red pepper pesto, or arugula pesto all produce delicious variations.
