Ingredients
Here’s everything you’ll need to create this creamy slow cooker masterpiece:
- 4 boneless, skinless chicken breasts – Lean, tender, and ideal for soaking up flavors. (Chicken thighs can also be used for juicier meat.)
- 1 can (14–15 oz) diced tomatoes – Use fire-roasted for smoky depth or Italian-seasoned for convenience.
- 1/2 cup tomato sauce – Smooth, concentrated flavor base.
- 1/2 cup chicken broth – Adds moisture and balances richness.
- 3/4 cup heavy cream (or half-and-half) – For that luxurious, creamy texture.
- 2 tablespoons cornstarch + 2 tablespoons water – Optional thickener for the sauce.
- 3 garlic cloves, minced (or 2 teaspoons garlic powder) – A classic flavor foundation.
- 1 teaspoon onion powder – Adds savory depth.
- 1 teaspoon dried basil (or 1/4 cup fresh basil, chopped) – The star herb of the dish.
- 1/2 teaspoon dried oregano – For an Italian-style balance.
- 1/2 teaspoon salt – Adjust to taste.
- 1/4 teaspoon black pepper – Enhances overall flavor.
- 1/4 teaspoon red pepper flakes (optional) – Adds a subtle heat.
- 1/2 cup grated Parmesan cheese – For a cheesy richness.
- Fresh basil, finely chopped – Stirred in at the end for a burst of freshness.
Step-by-Step Instructions
Step 1: Prepare the Chicken
Place the chicken breasts at the bottom of your slow cooker. If the breasts are very thick, you may butterfly them or lightly pound to even thickness for consistent cooking.
Step 2: Build the Sauce Base
In a mixing bowl, combine the diced tomatoes, tomato sauce, chicken broth, garlic, onion powder, dried basil, oregano, salt, black pepper, and red pepper flakes. Stir until well mixed. Pour this mixture over the chicken.
Step 3: Slow Cook to Perfection
Cover and cook on low for 5–6 hours or high for 3–4 hours. The chicken should reach an internal temperature of 165°F (74°C) and be fork-tender.
Step 4: Add the Cream and Cheese
About 30 minutes before serving, remove the chicken briefly and stir in the heavy cream and Parmesan cheese. If you prefer a thicker sauce, whisk cornstarch with water to make a slurry, then stir it in. Return the chicken to the slow cooker and let it simmer gently until everything is creamy and cohesive.
Step 5: Finish with Fresh Basil
Just before serving, stir in the fresh chopped basil for a fragrant, vibrant finish.
Step 6: Serve and Enjoy
Plate the chicken with plenty of sauce over your choice of pasta, rice, or mashed potatoes. Garnish with additional Parmesan and basil if desired.
Cooking Tips for the Best Results
- Avoid Curled or Grainy Sauce – Always add cream toward the end of cooking, not at the beginning. This prevents curdling.
- Use Full-Fat Dairy – Skim milk or low-fat creams tend to split in slow cookers. Heavy cream or half-and-half works best.
- Don’t Overcook Chicken – Check at the lower end of cooking times. Overcooked chicken can become stringy.
- Boost Flavor with Browning – For extra depth, lightly sear the chicken breasts in a skillet before adding them to the slow cooker.
- Layering is Key – Always place chicken first, sauce second, and dairy last.
Variations
- Cheesy Upgrade – Add mozzarella or provolone along with Parmesan for a gooey, cheesy sauce.
- Spicy Kick – Stir in red pepper flakes, cayenne, or a splash of hot sauce.
- Vegetable-Packed – Add spinach, mushrooms, zucchini, or bell peppers.
- Different Proteins – Swap chicken for turkey cutlets, pork chops, or tofu.
- Low-Carb Version – Serve over cauliflower rice or zucchini noodles.
- Dairy-Free – Use coconut milk instead of cream and nutritional yeast instead of Parmesan.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 3 days.
- Freezer: Freeze cooked chicken and sauce in freezer bags for up to 3 months. Thaw overnight before reheating.
- Reheating: Warm gently on the stovetop or microwave. If sauce thickens, add a splash of broth or cream.
What to Serve with Creamy Tomato Basil Chicken
- Pasta – Spaghetti, penne, or fettuccine soak up the sauce beautifully.
- Rice or Quinoa – A lighter alternative to pasta.
- Mashed Potatoes – For the ultimate comfort-food combo.
- Roasted Vegetables – Broccoli, carrots, or zucchini balance the richness.
- Crusty Bread – Perfect for mopping up the creamy tomato sauce.
Expert Cooking Insights
