• 1/2 tsp black pepper

How to make Slow Cooker Creamy Tomato Basil Chicken

1. Sauce it up: Add pasta sauce, diced tomatoes, garlic, salt, pepper, Italian seasoning, and half of the basil into your slow cooker. Stir everything together like you mean it.
2. Creamy base: In a bowl, whisk your heavy cream with corn starch until smooth. Add to the slow cooker and mix it in.
3. Nestle the chicken: Place your chicken breasts into the sauce, pressing them down so they’re nice and cozy.
4. Slow cook love: Cover and cook on LOW for 3 to 5 hours, until the chicken hits 165°F. (Pro tip: more chicken = longer cook time.)
5. Final flourish: Stir in the remaining basil or a spoonful of basil pesto right before serving.
6. Serve & savor: This is dreamy over pasta, rice, or with a side of roasted veggies.

Recipe Tips

• No basil? No worries. Basil pesto is a flavor-packed stand-in.
• Curdle control: Use heavy cream or evaporated milk—skip low-fat if you want a smooth sauce.
• Spice things up: Add a pinch of red pepper flakes for a little heat.
• Flour instead of corn starch? Go for it—just mix well before adding.
