This meal is a perfect, easy dish that cooks itself while you’re busy with other things. It’s made in the crockpot and it takes less than five minutes to assemble before you leave for work. Cook the chicken, pesto, and lemon while you are away, then cook pasta and mozzarella cheese, which are added before serving.
The Ingredients
Not many ingredients and very little prep. Find the full recipe in the recipe card below the images.
This recipe starts with boneless, skinless chicken breasts, seasoned generously with salt and pepper for flavor. A full jar of Classico Traditional Basil Pesto (about one cup) adds rich, herby depth, while sliced salted butter and the juice of half a fresh lemon bring richness and brightness. Once the chicken is cooked, rotini pasta—cooked al dente and well-drained—is stirred in with grated parmesan to coat everything in the buttery pesto sauce. Shredded mozzarella is sprinkled over the top to melt, and a touch of dried basil finishes it off for a simple but satisfying meal.
How to Make Pesto Mozzarella Chicken Pasta
This comes together quickly in the slow cooker, see how I do it.
Step 1 – Place the chicken in the slow cooker and season with salt and pepper. Spread the pesto over the top, then layer on the sliced butter and squeeze fresh lemon juice over everything.
Step 2 – Cover and cook on LOW for 5–6 hours without lifting the lid. Once done, use two forks to shred the chicken directly in the slow cooker.
Step 3 – Add the cooked and drained rotini pasta along with the parmesan cheese. Stir well to combine.
Step 4 – Sprinkle the mozzarella cheese over the top, cover again, and let it melt for about 15 minutes before serving.
Tips and Serving Suggestions
Use a jar of sun-dried tomato pesto instead of basil pesto for a change
Add sliced mushrooms for added texture.
Change the pasta shape; you can use any hearty pasta shape such as bow-tie pasta or penne.
This meal is great on it’s own, but also great if you add a salad or garlic bread.

“This is now in my regular rotation! I do add a bit of pasta water at the end to loosen it up though. About a coffee cup full (1/2 -1 cup) before I top it with the mozzarella cheese.“

Ingredients
- 1 1/2 lbs. chicken breasts, (1.5-2 pounds works fine, 3 chicken breasts)

These items don’t get added until the end
- 1 lb. dried rotini pasta , (cooked and drained, see directions for more info)
- 1/2 cup grated parmesan, (I use the powdery shake bottle type)
- 2 cups shredded mozzarella
- 1/4 tsp. dried basil to garnish
Instructions
- Add the chicken to the slow cooker. Sprinkle with the salt and pepper. Spread over the pesto, squeeze the lemon juice over the chicken. Cut the butter into slices and lay over the chicken.
- Cover and cook on low for 5-6 hours without opening the lid during the cooking time.
- Near the end of the cooking time, cook the pasta according to the package directions and drain well.
- Shred the chicken with 2 forks. Add the cooked pasta and the parmesan cheese, stir everything until the pasta is coated with the buttery pesto sauce and the chicken is evenly dispersed throughout the pasta. Add the mozzarella cheese over the pasta. Cover for about 15 more minutes or until the cheese has melted.

I have never found a crockpot recipe that my family actually likes. They are usually so bummed when they see it out on the counter. Not anymore! They loved this recipe. It was moist and flavorful. Definitely going into the dinner rotation.
Do u drain the crock pot before adding noodles?
No, that is the sauce for the pasta 🙂
I want to try some of your recipes
Would it be the same if I used chicken thighs instead or should I change the weight?
It would be the same
Would happen to have instant pot instructions?
I did tonight! Only thing different was add a little chicken broth and cooked it for 40 minutes so it would be super tender. Took the chicken out added the noodles on sauté mode and poured in the rest of the chicken broth. Drained out all of the broth and put the chicken back in and added the cheese!
Can I use orange juice beside lemon juice?
I think that would add sweetness instead of a tanginess in this recipe. It would be hard to say without trying.
I made this exactly as the recipe was written and my family would not eat it. We found it very dry and tasteless. I probably will not make this again.
While the flavor was ok, we also thought it was extremely dry. I thought about adding a can of cerream of chicken soup, but I didn’t.
This was super easy, and really good. We added crescent rolls and mixed veggies on the side, and even the kids ate it. And said yes to having it again. Win, win!!
So easy – and a VERY delicious crowd pleaser!
Granddaughter found this recipe and asked me to make it when she visited. Now, she requests this every time she visits!!
