Slow-simmering chicken thighs in a tomato-based sauce yields tender, juicy meat packed with flavor. Serve this Crock-Pot Italian chicken over your favorite pasta, or spoon it over steamed or roasted vegetables for a low-carb option.

Choosing a sauce

For best results use a marinara or tomato-basil spaghetti sauce that is low in sugar. A lower-sugar sauce is not only healthier but less likely to scorch during long, slow cooking. Aim for a sauce with six grams of sugar or less per serving.

You don’t have to use a specific brand—choose a low-sugar marinara or make a homemade tomato sauce if you prefer. A simple vegetable-rich marinara also works well and brings extra depth to the dish.

Prepping and cooking Crock-Pot Italian chicken

Start by thinly slicing a large yellow or sweet onion and placing the slices in the bottom of the Crock-Pot. Trim any large pieces of fat from six boneless, skinless chicken thighs and arrange the thighs on top of the onions.

While chicken thighs are the preferred choice for this preparation because they stay moist and develop great flavor, you can substitute chicken breasts, tenders, or fillets. If using chicken breasts, consider increasing the olive oil, butter, and water slightly, since breast meat tends to be leaner and drier.

Season the chicken with pantry staples such as garlic salt, freshly ground black pepper, red pepper flakes, Italian seasoning, and dried basil. These additions aren’t required but will enhance the overall flavor. Drizzle the chicken with a little extra virgin olive oil and a tablespoon of melted butter to give the dish a rich finish.

Pour a jar of marinara or tomato-basil spaghetti sauce over the seasoned chicken and add about 1/4 cup of water to help prevent the sauce from sticking or scorching. Cover and cook on high for three hours or on low for six hours.

During the final 30–60 minutes of cooking, remove the lid and switch the Crock-Pot to high to reduce excess liquid. At this point the chicken will easily shred with two forks. Taste and adjust seasonings as needed—add more herbs, pepper, or garlic salt to suit your preference.
