Slow Cooker Italian Chicken and Marinara

This Italian chicken gets its flavor from simmering all day in the slow cooker in a rich marinara sauce!

My crock pot never goes into hibernation. Not even in the dead of summer. Not to offend my grill or anything, because I love that, too, but when was the last time it made me saucy chicken (aka fall-apart-tender comfort food)?

Now, let me be honest. I don’t usually go for crock pot chicken recipes (or slow cooker chicken recipes – which name are we committing to?) that require pre-cooking. It just seems to negate at least a little bit of the ease of using the good ol’ “toss together, set it, and forget it” machine. But with this recipe? The prep is worth it. A homemade marinara always is.

The good news is that the sauce takes no more than 15 minutes to come together and once it’s fragrant and bubbling, you simply combine it with chicken breasts and cook on low for 6 hours, or 8 hours depending on your crock pot settings. The result is unbelievably tender chicken that’s swimming in sweet and garlicky tomatoes. Fresh basil and a hearty grating of Parmesan cheese and it’s true comfort.

If you want to go the extra step and melt some fresh mozzarella on top, you can even achieve a lighter, low calorie chicken parmesan without breadcrumbs…and friends I’ve tried it. It’s great. Half the hassle for so much of the flavor.

Slow Cooker Italian Chicken and Marinara

Servings: 6 Servings


  • 2 tablespoons olive oil
  • 1/2 cup finely chopped onion
  • 4 garlic cloves minced
  • 1 28- ounce can crushed or ground peeled tomatoes
  • 1 6- ounce can tomato paste

  • 6 5- to 6-ounce chicken breasts (2 pounds total)
  • ½ cup packed fresh basil finely chopped
  • ¾ cup freshly grated Parmesan cheese


  • Heat the olive oil in a large stock pot set over medium heat. Add the onion and garlic and cook, stirring occasionally, until softened and beginning to turn a golden, about 7 minutes. Lower the heat if they begin to burn at any point. Add the crushed tomatoes and the tomato paste and stir until the mixture is smooth and well-combined. Add the oregano, sugar, salt, and pepper; stir, and bring the mixture to a simmer.
  • Pour 2 cups of the sauce in the base of a 6-quart slow cooker. Add the chicken breasts and pour the remaining sauce evenly over the top. Cook on low for 8 hours.
  • To serve, divide the chicken breasts among 6 serving plates, spoon 2 tablespoons of the marinara sauce over the top, and sprinkle each evenly with the basil and Parmesan cheese.

    Yum! Looks so good. I am going to make this since I have a lot of chicken in my freezer lol. I sent you an email asking if you think putting nutella in cookies and then in the oven is a good idea or if it will burn lol

    This looks heavenly! I will be trying it as soon as I finish the detox I’m on right now. (It’s a healthy one…I do get to eat, just mostly vegetarian). I have two weeks to go and then I can eat great food like this again! I just want to say that your blog about your journey is incredibly inspirational. It brought tears to my eyes as I read it. I can’t wait to read your book when it comes out!

    Hey Andie – Do you think the sauce would work without the sugar? I’ve never made homemade marinara (shameful, I know) but am trying to avoid added sugar whenever possible. I know it’s not much in the grand scheme of the recipe, so will use it if it really enhances the flavor.

    Thanks for all of the new recipes lately. I had turkey meatloaf, broccoli and mashed sweet potatoes this week. SO GOOD!! Definitely going into permanent rotation.

      OK, so here’s the thing: normally I’d say to feel free to omit the sugar, but this marinara recipe is so sacred to me (it’s my beloved stepdad, PJ’s, recipe) and I really do believe that the sweetness is part of the secret to its incredible flavor. So, I’d say don’t remove it completely, but perhaps cut down the 3 tablespoons I call for to 1 tablespoon. That should still sweeten it slightly without adding many grams of sugar serving. Sound good?

    This looks delicious and healthy! I especially like the ease of making the sauce, as it usually takes me quite a long time to prepare a good pasta sauce. Thanks Jess for the suggestion of the fresh basil, that would enhance the flavor nicely!
