Step-by-Step Instructions
Step 1: Sear the Chicken (Optional but Recommended)
Heat olive oil in a skillet over medium-high. Season chicken with salt, pepper, and paprika. Sear for 2–3 minutes per side until golden. This step locks in flavor.
Step 2: Prepare the Sauce
In your slow cooker, combine crushed tomatoes, chicken broth, garlic, onion, Italian seasoning, and Parmesan. Stir well.
Step 3: Add Chicken
Place seared chicken breasts into the sauce mixture, ensuring they’re fully coated.
Step 4: Slow Cook
- Cook on LOW for 6 hours or HIGH for 3–4 hours until chicken is tender.
Step 5: Add Cream & Basil
Stir in heavy cream and fresh basil 30 minutes before serving. This ensures a rich, smooth sauce.

Sprinkle with Parmesan and more fresh basil before plating.

Common Mistakes to Avoid

- Skipping the sear – While optional, searing enhances depth of flavor.
- Not seasoning enough – Taste before serving; adjust salt and Parmesan for balance.
Storing Tips for the Recipe
- Refrigerate: Store leftovers in an airtight container for up to 4 days.
- Freeze: Freeze chicken and sauce (without cream) for up to 2 months. Add cream when reheating.
