Step-by-Step Instructions
1. Prepare the Chicken
Place the chicken breasts at the bottom of your slow cooker in a single layer.
2. Mix the Sauce
In a medium bowl, combine:
-
Diced tomatoes
-
Tomato sauce
-
Heavy cream
-
Chicken broth
-
Grated Parmesan cheese
-
Onion
-
Garlic
-
Dried basil, oregano, salt, black pepper, and optional red pepper flakes
Mix everything thoroughly until well combined.
3. Add to the Slow Cooker
Pour the tomato mixture over the chicken, making sure the breasts are well-coated.
4. Cook Low and Slow
Cover and cook on low for 4–6 hours, or until the chicken is fork-tender and cooked through.

Expert Tips & Tricks
-
Use thighs for extra juiciness: Chicken thighs can be swapped in if you prefer darker, more flavorful meat.
-
Make it a complete meal: Add chopped spinach, kale, or mushrooms during the last hour of cooking for added nutrients.
-
Thicken the sauce: If you prefer a thicker sauce, stir in a cornstarch slurry (1 tbsp cornstarch + 1 tbsp water) during the final 30 minutes.
-
Dairy-free option: Use coconut cream in place of heavy cream and a dairy-free cheese alternative.
-
Want more zest? Add a splash of balsamic vinegar at the end for a punch of brightness.

FAQs About Slow Cooker Creamy Tomato Basil Chicken
Can I use frozen chicken breasts?
Yes, but make sure they are thawed completely before placing them in the slow cooker for food safety and even cooking.
What if I don’t have an immersion blender?
No worries! You can skip blending for a chunky, rustic sauce—or pour the sauce into a regular blender (in batches, if needed), blend carefully, then return it to the slow cooker.
Can I use fresh tomatoes instead of canned?
Yes! Use about 2 cups of chopped, fresh tomatoes. If they are very juicy, reduce the broth slightly to avoid a watery sauce.
Is this keto-friendly?
Absolutely. This dish is naturally low in carbs and high in fat—ideal for a ketogenic diet.
How do I make this spicier?
Increase the crushed red pepper flakes to 1/2 tsp or add a diced jalapeño to the sauce mix.
