I have been craving Italian food, especially Chicken Parmesan. Since I spend my days chasing toddlers, homeschooling, and running a business, I prefer easy keto recipes for dinner. 

I made this delicious Italian casserole with a low-carb marinara sauce for an easy keto-friendly meal. You could make this Lazy Low Carb Chicken Parmesan from start to finish in the crockpot, but the juices from the chicken slow-cooking tend to make the marinara sauce a bit watery. Therefore, I prefer to make a casserole with cooked shredded chicken so that all the ingredients can bake together for the most amazing flavor. 


  • Chicken Breasts – These are going to be cooked and shredded. It won’t matter about their thickness, but thinner breasts will cook faster no matter what method you are using. If you prefer, you can use chicken thighs for added fat. 
  • Marinara Sauce – There are several keto-friendly marinara sauces available. Make sure to look at the ingredients to find one with no sugar-added. I’ve included a list in this post with several different options. 
  • Zucchini – This vegetable is the perfect low-carb alternative for noodles. Once spiralized, they cook quickly and have a nice texture to stand in for high-carb pasta.
  • Grated Cheeses – It’s always best to grate your cheese for Lazy Keto Chicken Parmesan Casserole when following a keto diet. Parmesan and Mozzarella cheese make a fabulous combination in this recipe. Most pre-shredded cheeses contain fillers to keep the cheese from sticking together, which can add carbs.

Below is a step-by-step pictorial for those who need a visual. Make sure to scroll to the bottom of the post for the printable recipe card with the full ingredient list and detailed instructions.

Step 1: First, cook your chicken breasts in the crockpot for the shredded chicken. Once the chicken is ready, preheat the oven and grease a 13×9-inch casserole baking dish. Place the cooked, shredded chicken breasts in the dish. Make sure to check out how to make shredded chicken in the crockpot for detailed instructions.

Step 2: Pour the jar of marinara sauce on top of the chicken and sprinkle the parmesan cheese along with mozzarella cheese and Italian seasonings. 

Step 3: Bake until the cheese is slightly browned and bubbly.

Step 4: Spiralize the zucchini into noodles. Saute them in butter, salt, and pepper for three or four minutes. 


  • Try sprinkling a little parmesan cheese on the top right before you eat them, for just a little more added flavor. 
  • To add Italian flavor to the shredded chicken, I sprinkle a little Italian seasoning or garlic powder before adding the marinara sauce.
  • Zucchini has high water content. Place the sauteed zucchini on paper towels so that some of the moisture drains.


While this recipe is not the same Chicken Parm you’ll find at Italian restaurants, it’s a fantastic alternative. I used shredded chicken, a low-carb marinara sauce, and then served it over zoodles to make Chicken Parmesan keto-friendly. Zoodles are very low carb and are made by spiralizing zucchini into the shape of noodles. 


For the most tender and flavorful chicken, I slow cook chicken breasts in my crockpot all day. I simply cover the chicken breasts with chicken broth and salt and pepper. Then, at dinner, the chicken is ready to shred for the base of Low Carb Chicken Parmesan Casserole. Check out these step-by-step instructions for making how to make shredded chicken in the crock-pot. You could cook the chicken in the Instant Pot if you prefer, or grab a rotisserie chicken for convenience.


While I know that homemade is best, I choose my battles. Instead of making a homemade marinara sauce, I used a jarred variety. I have found several flavorful marinara sauces with no added sugars that are low in carbs. The lowest carb sauce is Rao’s brand. Other options are Mezzetta’s and the ALDI’s marinara sauce. My local Walmart carries both the Rao’s and the Mezzetta’s.

I used a cheap spiralizer to make zucchini zoodles while the Low Carb Chicken Parmesan Casserole was in the oven. There are many larger countertop spiralizers, but I wanted something simple that wouldn’t take up space in my kitchen. I sauteed the zoodles in about a tablespoon of butter with salt, pepper, and Italian seasoning. Then, I laid them on a paper towel to absorb excess moisture. You can follow these instructions for spiralizing zoodles.

While this isn’t a traditional Chicken Parmesan recipe, it turned out delicious. There are times I need quick options for dinner, like this recipe. The incredible Italian flavors of this dish shine through, and the ease of preparation made this recipe a keeper.

I typically make a leafy garden salad with mixed greens to go with this low-carb Chicken Parmesan recipe. Other options include roasted broccoli or asparagus for a simple keto-friendly side dish if you miss bread, Keto Cheddar Garlic Biscuits, or Keto Cheesy Garlic Chaffle bread pair perfectly.


If you prefer the standard fried chicken breasts in chicken parmesan, it can still be made keto-friendly. In this particular recipe, my focus was easy, so I used shredded chicken instead. However, you can make Keto Fried Chicken breasts with that traditional bread crumbs taste with an egg mixture and coconut flour, almond flour, or crushed pork rinds.

  1. Whenever I made zoodles there is always a lot of water that puddles on the plate. Any suggestions for what I am doing wrong?

    1. Don’t peel the skin off. It holds the water in. Cook it for only a couple minutes until warm to keep them from getting mushy.

    1. Sorry about that! I have updated the recipe with the baking time. Thanks for bringing that to my attention.

    1. It would change the nutritional info but I’m sure you could use it. Let me know how it turns out.

    1. No, I don’t measure. I simply divide it evenly by the number of servings listed at the top of the recipe card.

    1. Hey Jo, so I precook my chicken in bulk and shred it for the freezer. However, one shredded medium chicken breast is just a little over a cup of chicken. I hope this answers your questions.
