Ingredients You Need
Chicken
- 2 to 2.5 pounds boneless skinless chicken breasts
- Use thighs if you prefer richer flavor and extra tenderness.
- 1 teaspoon kosher salt
- 1 teaspoon black pepper
- 1 teaspoon garlic powder
Tomato basil sauce
- 1 can (14.5 to 15 ounces) crushed tomatoes or tomato sauce
- Use fire roasted tomatoes for deeper flavor.
- 1 can (14.5 ounces) diced tomatoes, undrained
- Use petite diced if you want a smoother sauce.
- 3 to 4 cloves garlic, minced
- Use 1 to 1.5 teaspoons garlic powder if you run out of fresh garlic.
- 1 small yellow onion, finely chopped
- Use 1 teaspoon onion powder if you dislike chopping.
- 1 teaspoon dried Italian seasoning
- 1 teaspoon dried basil
- Use more fresh basil at the end if you love basil flavor.
- 1 teaspoon sugar
- This balances the acidity in canned tomatoes.
- 1 teaspoon salt, plus more to taste
- 1 teaspoon black pepper
Creamy ingredients
- 4 ounces cream cheese, softened and cut into cubes
- Use full fat for the creamiest texture; light cream cheese still works.
- 1 cup heavy cream
- Use half and half for a lighter sauce or full fat coconut milk for dairy free.
- 1 cup freshly grated Parmesan cheese
- Use a wedge and grate it yourself; pre-grated often clumps and tastes less fresh.
Fresh herbs and finishers
- 1 packed cup fresh basil leaves, chopped
- If you only have dried basil, add 1 extra teaspoon at the start and skip this.
- 1 to 2 tablespoons fresh parsley, chopped, optional
- Red pepper flakes to taste, optional, for a gentle kick
Pantry shortcuts and brand notes
- Use your favorite canned tomato brand; I like San Marzano style for sweeter flavor.
- Jarred minced garlic works in a pinch; use 1 to 2 teaspoons.
- Use pre-shredded rotisserie chicken and cut the slow cooker time in half; add it halfway through so it does not dry out.
Equipment
- 4 to 6 quart slow cooker
- Cutting board and sharp knife
- Measuring cups and spoons
- Small whisk or fork for mixing the cream ingredients
- Tongs or two forks for shredding or slicing the chicken
Quick Tips & substitutions
- Pat the chicken dry and season it generously so the meat tastes flavorful, not bland.
- Use thighs if you often overcook chicken breasts; thighs stay juicy longer.
- Stir the cream cheese and heavy cream in at the end so the sauce stays smooth and does not curdle.
- Use coconut milk and dairy free cream cheese for a dairy free version.
- Skip the sugar if your tomatoes taste naturally sweet.
- Add extra basil at the end if you want a stronger herb flavor.
- Cook on low for the most tender chicken; use high only when you feel short on time.
- Thicken the sauce with extra Parmesan or a tablespoon of tomato paste if it looks thin.
- Use gluten free pasta or serve over rice or potatoes if you avoid gluten.
- Taste and adjust salt and pepper after the sauce sits for a few minutes; the flavors settle and deepen.
How to Make Slow Cooker Creamy Tomato Basil Chicken Recipe
Step 1: Season the chicken
Pat the chicken dry with paper towels so the seasoning sticks well. Sprinkle both sides with salt, pepper, and garlic powder. Rub the seasoning into the chicken so every bite tastes seasoned.
Step 2: Build the tomato base
Add the crushed tomatoes and diced tomatoes to the slow cooker. Stir in the chopped onion, minced garlic, Italian seasoning, dried basil, sugar, salt, and pepper. Mix until everything looks combined and the spices spread through the tomatoes.
Step 3: Nestle in the chicken
Place the seasoned chicken into the slow cooker and push it down into the tomato mixture. Spoon some of the tomato mixture over the top of the chicken so it sits mostly covered. Cover the slow cooker with the lid.
Step 4: Cook low and slow
Cook on low for 4 to 6 hours, or on high for 2.5 to 3.5 hours. Check the chicken near the earlier time mark so it does not overcook. The chicken should feel tender and reach 165°F in the thickest part.
Step 5: Shred or slice the chicken
Lift the chicken out of the slow cooker and place it on a cutting board. Shred it with two forks or slice it into thick pieces, based on how you want to serve it. Set the chicken aside while you finish the sauce.
Step 6: Add the creamy ingredients
Turn the slow cooker to warm or low. Add the cream cheese cubes to the hot tomato mixture and whisk or stir until they melt and blend into the sauce. Pour in the heavy cream and sprinkle in the Parmesan, then stir until the sauce turns smooth and creamy.
Step 7: Add fresh basil and adjust seasoning
Stir in the chopped fresh basil and taste the sauce. Add more salt, pepper, or a pinch of sugar if the sauce tastes too sharp. Add red pepper flakes if you want a gentle heat.
Step 8: Return the chicken to the sauce
Place the shredded or sliced chicken back into the creamy tomato basil sauce. Stir gently so the sauce coats every piece of chicken. Let it sit on warm for 5 to 10 minutes so the flavors mingle.
Step 9: Serve
Spoon the creamy tomato basil chicken over your favorite base like pasta, rice, or mashed potatoes. Add extra basil and Parmesan on top if you feel fancy. Serve hot and enjoy that rich, cozy sauce.
Recipe Variations
- Gluten free: Serve over gluten free pasta, rice, polenta, or mashed potatoes instead of regular pasta.
- Low carb: Serve over zucchini noodles, spaghetti squash, steamed broccoli, or cauliflower mash.
- Dairy free: Use full fat coconut milk and dairy free cream cheese, and skip the Parmesan or use a dairy free version.
- Extra veggies: Add sliced mushrooms, spinach, or chopped bell peppers during the last hour of cooking.

- Extra protein: Stir in cooked chickpeas or white beans during the last 30 minutes.
