I’m in love with this Slow Cooker Italian Chicken and Peppers. I’m just going to lay it out there. It’s every bit as easy, delicious, and versatile as those Slow Cooker Taco Chicken Bowls that everyone loves so much, but with a marinara base and Italian herbs and spices.

How to Serve Italian Chicken and Peppers

I ate this saucy shredded Italian chicken and peppers spooned over my Garlic Parmesan Polenta, but you could totally spoon this over a bowl of pasta or rice. BUT my favorite way to eat this saucy mix is to spoon it into rolls or a loaf of Italian bread, top it with some mozzarella, and make yourself the most amazing slow cooked sandwich ever. EVER.

What Size Slow Cooker Do I Need?

I used a 5 quart slow cooker, but it was only about half full, so you could probably get this to fit into a 3 quart slow cooker.

Keep it On Budget

  • Bell Peppers: I added a red bell pepper to the mix for color and visual appeal. You can totally just use three green bell peppers if that’s what your budget allows, or go all out and get a trio of colors (green, yellow, and red or orange). It will taste great either way you go.
  • Sauce: I used the most basic, generic jarred pasta sauce for this recipe, so don’t think you have to get very fancy with it.
  • Chicken: I always buy my chicken when it’s on sale so that it’s at least close to affordable (I bought this chicken a few weeks ago and stored it in the freezer). You could even cut it down to one chicken breast and add in extra peppers and onions to bring the cost down further.

How to Make Slow Cooker Italian Chicken and Peppers – Step by Step Photos

Sliced peppers and onions on a wooden cutting board

Start by slicing three bell peppers and one medium onion into 1/4-inch slices. I used two green bells peppers and one red, for extra color.

First Layer Peppers and Onions in the slow cooker

Lay about half of the onions and peppers in the bottom of a 4-quart or larger slow cooker.

Raw Chicken and Herbs on the peppers and onions in slow cooker

Lay two boneless, skinless chicken breasts or thighs (or 1.5 pounds total) over the peppers and onions. Season lightly with salt and pepper, then sprinkle 1 tsp of basil and 1 tsp of oregano over top.

More peppers and onions and marinara sauce in the slow cooker

Add the second half of the peppers and onions, then pour an entire 24oz. jar of marinara sauce over top.

Cooked chicken and peppers in the slow cooker

Put the lid on the slow cooker and cook on high for four hours or low for eight hours. Then it will look a little something like the photo above… not too appetizing, I know. Just wait.

Tongs picking up a piece of chicken in the slow cooker

Take a pair of tongs and begin to stir the mixture and shred the chicken. The chicken should be so tender that it falls apart when pinched with the tongs, so I just stirred and pinched…

Until it looked like this, which only took a few minutes. YUM. Now it’s done! That’s it! Seriously.

I ate mine over fried cakes of Garlic Parmesan Polenta, but I would also love to stuff it into a roll with some mozzarella.

  1. This is delicious! I serve it over pasta. The only change I made to the recipe was frozen peppers instead of fresh.

  2. This was so delicious! I wanted a delicious, healthy and easy to make for a Sunday dinner. I put the chicken breasts in frozen and used a can of crushed tomatoes with extra spices instead of the marinara sauce. It was ready to go in 3.5 hours on high. We ate on toasted french bread with mozzarella and pepperoncinis and it was a hit. I’m constantly on the look for new recipes and this one is a keeper! Thanks!

  3. So easy and tasty! Spooned mine up over baked spaghetti squash and am using hoagie rolls for garlic bread. May add mushrooms to the mix next time.

    1. This is one of my favorite slow cooker recipes!! I usually precut my onions and peppers and freeze them in quart sized bags so they are ready to go (specifically for this recipe!). ย Just as a preference, I dice my peppers and onions. Itโ€™s delicious on pasta, rice or rolls!! ย This also reheats very well!! Thank you for this awesome recipe for one busy momma!!

  4. Just made this, spooned it into a hunk of bread, and ate it. Delicious! I made it in my Instant Pot as well- 20 minutes on pressure cook, then 10 minutes before releasing the pressure, and then about 5 minutes on saute just to thicken up the sauce. Came out perfect! I’m looking forward to the leftovers.

    1. The slow cooker just serves to make the chicken tender and shreddable. You can make a quick version of this on the stove top by sautรฉing the peppers and onions in a skillet until tender, then adding the sauce and simmering until the peppers are soft. Then you can spoon the peppers and sauce over the whole chicken breast, or even bake them with the sauce in the oven.

  5. Just turned the recipe in a “Italian Way” , I’ll let you know the result in a few hours :-)

  6. Would this work in the slow cooker if I did all ingredients but peppers and onions and used a frozen bag of peppers and onions instead at the end before serving…just curious, since I have a bag!!

    1. Hmm, it’s hard to say without trying it, but it sounds like it would work. You’d basically just be slow cooking chicken in marinara, which isn’t a bad thing. :)

  7. Made this last night & added garlic and basil purรฉe, but I wasnโ€™t impressed with the flavors. ย Lots of leftovers though, so had it again this morning with feta and a fried egg on top . . . YUMMY!

  8. I can home last night with absolutely no plan for dinner. I saw this recipe and had all the ingredients, but did not have 8 hours. I followed the ingredients exactly, but put it in the instant pot for 20 minutes and it was DELICIOUS. I just put it back to saute while I was shredding the chicken and it thickened right up. We had it served over pasta. My 3 year old even had seconds and he’s not a big eater at dinnertime.

  9. This worked so well! So easy and came out with perfectly cooked chicken and lovely flavour. I’ve used this on pasta, bread, and even just by itself with salad. Freezes really well also so perfect for bulk-cooking ahead of time.

  10. I made this, it was good, especially since I used only low fat plain breasts. I added one tablespoon of Italian fish sauce at the end to add some flavor – some anchovy fillets (oil-packed) added at the beginning would work too.

  11. Made this tonight in the instant pot. Delish !!the only ingredient addition I made was a tablespoon of garlic. Yummy! Served On top of zoodles and fettuccine. Thank you !
