Ingredients

Save

• 4 boneless, skinless chicken breasts
• 2 tablespoons olive oil
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon garlic powder
• ½ teaspoon onion powder
• 1 can (15 oz) crushed tomatoes
• ½ cup (120 ml) low-sodium chicken broth
• ½ cup (120 ml) heavy cream (or coconut milk for dairy-free)
• 4 garlic cloves, minced
• 1 tablespoon dried basil or ¼ cup fresh basil, chopped
• ¼ cup grated Parmesan cheese (optional)
• 1 tablespoon cornstarch mixed with 2 tablespoons water (optional, for thickening)
• Fresh basil leaves, for garnish

Instructions

Prepare the Chicken

Start by patting the chicken breasts dry with paper towels. Season both sides evenly with salt, pepper, garlic powder, and onion powder. This step helps to build a flavorful base before the chicken even hits the slow cooker.

If you have a few extra minutes, sear the chicken in a hot skillet with olive oil—about 2–3 minutes per side—until lightly golden. It’s optional, but this quick step adds depth and a beautiful texture to your final dish.

Add Everything to the Slow Cooker

Place the chicken breasts in the bottom of your slow cooker. Pour in the crushed tomatoes and chicken broth, then add the minced garlic and basil. If you’re using Parmesan cheese, sprinkle it in now to melt into the sauce during cooking.

Stir everything gently around the chicken so the flavors begin to marry even before the heat starts.

Cook Low and Slow

Cover your slow cooker and set it on LOW for 4–5 hours or HIGH for 2–3 hours. You’ll know it’s ready when the chicken is cooked through, tender enough to shred with a fork, and infused with the tangy sweetness of tomatoes and fragrant herbs.

Add the Cream and Finish the Sauce

About 30 minutes before the chicken is done, stir in the heavy cream (or coconut milk for a dairy-free option). If you prefer a thicker sauce, now is the time to whisk in the cornstarch slurry.

Let the dish cook for the final half hour so the sauce becomes rich, velvety, and irresistible.

Serve and Enjoy

Transfer the chicken to plates or bowls and spoon the creamy tomato basil sauce generously over the top. Garnish with freshly chopped basil for a pop of color and fresh aroma. For an extra hit of umami, add a sprinkle of Parmesan just before serving.

Tips and Tricks

• Use Fresh Basil When Possible: Fresh basil brightens the entire dish and adds authentic flavor. Add it at the end for maximum impact.
• Don’t Overcook: Chicken breasts can dry out if overcooked. If your slow cooker runs hot, check the chicken a bit early.
• Try Chicken Thighs: Prefer darker meat? Chicken thighs are a great substitute and stay extra juicy.
• Balance the Flavors: Taste the sauce before serving. You might want a pinch more salt, pepper, or a squeeze of lemon juice to brighten things up.
• Make It Spicy: Add a pinch of red pepper flakes if you like a little heat.

Serving Suggestions

Save

You can dress this dish up or down depending on the occasion. It’s as perfect for a quiet dinner as it is for a special gathering.

• Pasta Perfection: Spoon the creamy tomato basil chicken over penne, spaghetti, or linguine. The sauce clings beautifully to pasta!
• Rice or Quinoa: Fluffy white or brown rice, or even nutty quinoa, make great beds to soak up every drop of sauce.
• Mashed Potatoes: For an ultra-comforting option, serve with buttery mashed potatoes—so good with the rich sauce.
• Crusty Bread: Don’t forget a slice (or three) of crusty bread to mop up the leftovers on your plate.
• Low-Carb Ideas: Pair with cauliflower rice or zucchini noodles if you’re keeping it light.

Add a side of steamed veggies like green beans, asparagus, or roasted broccoli to round out your plate and balance the richness.

Storage Instructions

This dish stores wonderfully and can be made ahead for meal prep or leftovers.

• Refrigerate: Store in an airtight container in the fridge for up to 3–4 days.
• Freeze: Cool completely and freeze individual portions in freezer-safe containers for up to 3 months. Great for quick meals later!
• Reheat Gently: Reheat on the stovetop over low heat or in the microwave at medium power. Stir occasionally to prevent the cream from separating.
• Avoid Boiling: High heat can break the sauce—gentle reheating is key to maintaining that creamy texture.

Possible Variations

• Add Veggies: Stir in fresh spinach, chopped zucchini, bell peppers, or mushrooms during the last hour of cooking.
• Make It Dairy-Free: Swap out the cream and cheese for full-fat coconut milk and omit the Parmesan.
• Herb Swap: No basil? Try oregano or thyme.
• Tomato Boost: Mix in sun-dried tomatoes for a sweet, tangy burst of flavor.

FAQ

Can I use chicken thighs instead of breasts?
Yes! Chicken thighs are a flavorful, juicy option that work perfectly in this recipe. You can follow the same cooking times.

What if I don’t have heavy cream?
You can substitute with half-and-half, full-fat coconut milk, or a plant-based cream. The texture may vary slightly but it will still be delicious.

Will this work with frozen chicken?
It’s best to thaw chicken before using in a slow cooker for food safety and even cooking. If you must use frozen, make sure it fully cooks and reaches an internal temp of 165°F (74°C).

Can I prepare this ahead of time?
Absolutely! You can prep everything the night before and store it (uncooked) in the fridge. In the morning, just set it in the slow cooker and go.

How do I thicken the sauce without cream or cornstarch?
Let the sauce simmer uncovered in a pan on the stove after removing the chicken. This helps reduce and thicken the sauce naturally.
