What Is in Chicken Pasta Sauce?

CHICKEN: Chicken has fewer calories than most proteins, but on a keto diet, it’s all about watching carbs. Ground beef (or frozen meatballs!), Italian sausage or leftover chicken or turkey are all great choices, be sure they are all pre-cooked.

SAUCE: Low-carb spaghetti sauces are usually low or no-sugar (Rao’s is our favorite). Other low-carb sauces include this Alfredo (white sauce) which is extra creamy and can be used in place of spaghetti sauce. Add some milk or light cream to replace the diced tomatoes and adjust the seasonings, as desired.

VEGGIES: Red peppers add a crunchy texture to chicken pasta sauce, but for extra nutrition that also keeps it keto, add shredded zucchini, sliced mushrooms, spinach, or even finely chopped kale.

SEASONINGS: Try this Italian seasoning recipe instead of using store bought. Double the recipe and have it ready for adding to other dishes.

How to Make Chicken Pasta Red Sauce

  1. Saute onion until tender, add red pepper and garlic, and cook for 2 more minutes.
  2. Add diced tomatoes, spaghetti sauce, and seasonings.
  3. Bring sauce to a boil, then simmer until thickened (as per the recipe below).
  4. Add chicken and cook until chicken is heated through. Serve with shredded parmesan cheese.

PRO TIP: After the onions, red pepper, and garlic have been sauteed, add a little wine to the pan to deglaze it.

Tips For Tasty Sauce!

Make this sauce without the chicken for a low-carb, vegetarian marinara. Or purchase a rotisserie chicken and use it for this recipe and freeze the rest for future meals.

Any Leftovers?

  • Keep chicken pasta sauce in a covered container in the refrigerator for up to a week and reheat portions on the stovetop, as needed.
  • Refresh the flavors with a little extra salt and pepper or fresh garlic.
  • Top a Denver omelet, or scoop some over spaghetti squash, or lasagna roll-ups.
  • To freeze chicken pasta sauce, pour portions into freezer bags with the date written on the outside and freeze for up to 3 months.
