Adds smooth texture and enhances the deep tomato base of the sauce.

Garlic
Fresh garlic provides warmth and depth. Garlic powder can be substituted in a pinch.

Onion
Adds sweetness and balances the acidity of the tomatoes.

Fresh basil
Fresh basil gives the signature aroma of tomato basil chicken. Dried basil works too, but fresh is ideal.

Italian seasoning
A blend of herbs that complements the tomato sauce beautifully.

Olive oil

Salt and pepper

Step-by-Step Instructions

Step 1: Prepare the slow cooker base
Pour the crushed tomatoes and tomato sauce directly into the slow cooker. Stir gently to combine and create the base for the sauce.

Step 2: Add aromatics
Add minced garlic, chopped onion, Italian seasoning, salt, and pepper into the tomato mixture. Stir to distribute the flavors evenly.

Step 3: Add the chicken
Place the chicken breasts or thighs directly into the sauce. Make sure they are fully coated so they absorb all the flavors as they cook.

Step 4: Drizzle olive oil
Lightly drizzle olive oil over the top to enhance richness and prevent dryness during the slow cooking process.

Step 5: Slow cook to perfection
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours. The chicken should be tender and easy to shred with a fork.

Step 6: Add fresh basil
About 20 minutes before serving, stir in chopped fresh basil. This preserves its vibrant flavor and aroma.

Step 7: Optional shredding
For a rustic texture, gently shred the chicken in the sauce. For a more elegant presentation, leave the chicken breasts whole.

Step 8: Final seasoning
Taste the sauce and adjust salt or pepper if needed.

Step 9: Serve warm
