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.“

These items don’t get added until the end

- 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 loved this dish. I chose to use sundried tomato pesto instead and everything else the same. I will be making this meal again.
Made this tonight and wanted to convert recipe to WW points because it tasted so delicious!! It says serves 8….how much is one serving size?
The servings are approximate. I make a guess how many people it will serve after I serve my family dinner. I can’t say how much exactly each serving is. So sorry!
Per other comments, if I’m going to add whole milk to it to add some creaminess (since I don’t have cream), at what point should I do that?
I actually made it in a pan and it still tasted delicious! Thanks for the recipe!
I saw in the comments that it was pretty dry so i added 1/2 cup of milk. It was pretty Creamy.
If I want to add fresh mushrooms (to be cooked) when would you add?
You can add them in the beginning! Or even half way through if you want them more firm.
Why add lemon juice? Just wondering
Lemon is great with chicken and adds flavor to the whole dish.
I made this last night. I added a can of chicken broth and used real parm cheese. Then took it out of the crockpot, and into a 9×13 pan, sprinkled with the mozzarella cheese and placed it in the oven to get the cheese brown and melted. Husband still thought it was dry. IF I make it again, I will use 2 cans of broth and maybe some red pepper flakes. It had a good flavor. Just seemed like it was missing something.
We thought this was good but too dry. I added a jar of Alfredo sauce
to it and that made it creamier.
I cooked this for our family tonight. I used my pressure cooker instead of my crock pot. I would not recommend that to anyone. Chicken creates a lot of it’s own juices at it is, but even moreso in a pressure cooker, and it did not have the creaminess I hoped for. It was more of a buttery, pesto soup instead of sauce. I also need a lot more cheese.
I’ll try this again in my crock pot next time.
We added a jar of Alfredo sauce and it was amazing!
did you add in the alfreado sauce in addition to the pesto? if so when did you add the sauce?
