This 21 Day Fix Instant Pot Caprese Chicken is amazing in both the Instant Pot and the Crock Pot, making it a perfect warm weather dinner when you don’t want to heat up the kitchen! This post contains affiliate links for products I’m obsessed with. 
Confession #93 – I’m not the only one who is unwilling to admit summer is over. Despite the fact that Halloween and Pumpkin everything is taking over the planet, my summer garden is still hanging around…totally in denial of the impending change of seasons. Yay, right? 
My tomato plants, especially, will not quit, and I am always looking for yummy ways to use them before they get too ripe. And with the Back to School craziness, I am also always on the hunt for a good crock pot or instant pot recipe to make sure that dinner actually makes it way to the table. 
Enter this easy Caprese Chicken! I’m so in love with this dish. For those of you who have made my 21 Day Fix Balsamic Chicken with Zoodles, this meal is very similar. I wanted to see, though, what would happen if I used some of my fresh tomatoes in place of the canned stuff. Oh my word. Delish! And so easy. The most time consuming part is halving the tomatoes, so this can be easily assembled quickly on food prep day, before bed the night before, or early in the morning before work. 
When your busy day is over, you will come home to the amazing smell of effortless cooking, which is always the best kind for a weeknight, right? Throw some shredded mozzarella and basil on top and dig in!
We served ours over seasoned brown rice, but it could be eaten alone, with pasta, zoodles or whatever your heart desires. A perfectly yummy, let light end of Summer meal!

This 21 Day Fix Instant Pot Caprese Chicken is amazing in both the Instant Pot and the Crock Pot, making it a perfect warm weather dinner when you don’t want to heat up the kitchen!
Ingredients
- 1/2 large yellow or red onion, sliced
- 3–4 cloves fresh garlic, minced or pressed
- 1 lb. boneless, skinless chicken breasts
- 3 1/2 cups of cherry or grape tomatoes, halved
- 2 tbsp. balsamic vinegar (3 tbsp. for the IP)
- 2 tsp extra virgin olive oil
- 1 tsp. crushed red pepper (optional)
- sea salt and fresh ground pepper, to taste
- 2 tbsp. fresh basil, chopped
- 2/3 cup mozzarella cheese, shredded
- cooking oil spray
Instructions
- For the slow cooker: Spray your slow cooker with nonstick cooking spray – I used my EVO. Add sliced onions and garlic to the bowl and then cover with chicken breasts. Add chopped tomatoes, balsamic vinegar, olive oil, crushed red pepper (if using), salt and pepper. Cover and cook on low for 7-8 hours or high for 3-4 hours. Add basil and top with grated mozzarella cheese. Turn slow cooker on high and cover until the cheese has melted. Serve with brown rice, quinoa, whole grain or gf pasta, or zoodles! Yum!
- For the Instant Pot: Spray your Pressure Cooker with cooking oil spray and hit the saute function. Saute your onions until they begin to caramelize. Turn off saute and add in garlic and chicken, then top chopped tomatoes, balsamic vinegar, olive oil, crushed red pepper (if using), salt and pepper. Cover and set to manual for 15 minutes. After cook time, carefully switch to quick release and open the top of your pressure cooker when all the steam has released. Switch to saute and add in the mozzarella cheese and basil. Cook on saute until the cheese melts (2-3 minutes). Serve with brown rice, quinoa, whole grain or gf pasta, or zoodles! Yum!

Your recipes are amazing!! Thank you so much for blogging and sharing. I’m a tired mamma so easy, healthy and delicious are essential!!
Nancylynn says
You just made this (also tired) mamma’s day! Thank you and I am so very happy my blog is helping!
Monica says
Let’s pretend my chicken breast is still frozen…how would you cook it in the Instant Pot?
Nancylynn says
I would do the same thing as directed, but add some time. I’d say 5-10 minutes or so.
Hannah says
I see that a serving is 1 breast, but how many servings are in the whole recipe? Idk how many are in 1 lb. Thanks!
Nancylynn says
Sorry – four!
Betsy says
I am wanting to make this crock pot caprese recipe and wanted to double check on the balsamic vinegar- that it is only 2 tablespoons and no other liquids (chicken broth) are added to recipe. Just concerned it might be dry!
Happy to have found all your healthy recipes! Thank you.
Nancylynn says
Hi! Yes – you are correct! The tomatoes make so much extra juice, so it won’t be dry! Hope you enjoy it 🙂
Shannon says
How much is in a serving for your container count?
Nancylynn says
It’s 1/4 of the pot!
Katie says
Do you have a calorie count on this recipe?
Sanna says
“The most time consuming part is halving the tomatoes.” Try this hack: Put whole tomatoes on a plate. Invert another plate on top of the tomatoes. Insert sharp knife between the edges of the two plates, & halve ALL the tomatoes at once!
Nancylynn says
I have always wanted to try this!!!
Sanna says
Please do, & let me know what you think!
Barbara Miller says
Definitely made this tonight!! Flavors come together so nicely. Perfect for a new IP user…. just incredible
Thank you!
Nancylynn says
YAY!!!! I am so happy to hear this!!! <3 <3
Kara S says
I just got an Instant Pot for Christmas and this was my third recipe. I followed the cooking instructions but the chicken came out dry, I used defrosted boneless skinless chicken breast. Any recommendations? Should I cut the cook time down by a minute or two? Thank you!!
Nancylynn says
That is a bummer! Yes – try a minute or two less next time!
Chris says
Hello. This recipe is delicious. Unfortunately I have cooked it twice now in the instant pot and it comes out too liquidy. Is the sauce supposed to be very liquidy? Thanks.
Maggie says
I’m using an 8 quart instant pot that requires a cup of liquid to come to pressure. How did you get it to not burn?
Nancylynn says
The tomatoes are so juicy, it makes a ton of liquid! I would try it first to see if the burn message comes on before adding in extra liquid. Let me know how it goes!
Cathy Cook says
Made this tonight. Outstanding!
★★★★★
Nancylynn says
I’m SO glad!!
Martin says
This is one of the easiest and tastiest things I’ve made in the IP. Doubled the recipe and cooked it for 17 min.
★★★★★
Nancylynn says
That’s GREAT to hear!
Amy McMartin says
Made this tonight..yum!!
★★★★★
Nancylynn says
YAY! I have been food prepping this one a lot!
Kelly says
Can I use diced tomatoes instead? We are not big fans of tomatoes but this looks yummy!
Megan says
Can I use a different liquid than the balsamic vinaigrette?
Nancylynn says
Sure, but it won’t have the caprese taste!
Megan says
Do you have any other suggestions for the type of liquid that may work best?
Nancylynn says
A dry white wine?
Julie says
Any thoughts on making this in the oven? Maybe sear the chicken on a cast iron skillet and bake with the tomatoes?
Nancylynn says
YES! I think it would be delish!
