Ingredient Notes
What kind of chicken? Boneless, skinless chicken breasts are lean and cook beautifully in the slow cooker. For an even juicier, more forgiving result, substitute boneless, skinless chicken thighs. Thighs stay moist even if cooked a little longer.
What kind of diced tomatoes? Regular diced tomatoes work well. Fire-roasted diced tomatoes add a subtle smoky depth. Tomatoes with garlic and onion add extra flavor. Avoid tomatoes with added sugar or heavy seasoning — you want to control the flavor yourself.
Can I use crushed tomatoes instead? Yes. Crushed tomatoes will create a slightly thicker, smoother sauce. Use the same amount (14.5 ounces). Do not use tomato sauce or tomato paste — they are too concentrated.
What kind of heavy cream? Heavy cream (also called heavy whipping cream) creates the richest, most velvety sauce. Half-and-half will work but will result in a thinner, less creamy sauce. Do not use milk — it can curdle when combined with the acidic tomatoes.
Why add the cream at the end? Adding cream during the last 20–30 minutes prevents it from curdling. Dairy can separate when cooked for too long at high temperatures. Adding it at the end ensures a smooth, creamy sauce.
Fresh vs. dried basil: Dried basil has a more concentrated, slightly different flavor than fresh. If using fresh basil, add it during the last 30 minutes of cooking (or stir in just before serving) to preserve its bright, fresh flavor.
Step-by-Step Instructions
Step 1: Layer the Chicken
Place the 4 boneless, skinless chicken breasts in the bottom of your 4- to 6-quart slow cooker in a single layer. It’s okay if they overlap slightly — they’ll shrink as they cook.
Step 2: Add the Tomatoes and Seasonings
Pour the 1 can (14.5 ounces) of diced tomatoes (with their juices) over the chicken.
Sprinkle the 1 teaspoon of dried basil and 1 teaspoon of garlic powder evenly over the top.
Do not stir — the tomatoes and seasonings will distribute as they cook.
Step 3: Cover and Cook
Cover the slow cooker with the lid. Cook on:
-
LOW for 5 to 6 hours, or
-
HIGH for 3 to 4 hours
The chicken is ready when it is tender and cooked through (internal temperature of 165°F / 74°C) and easily shreds with a fork.
Step 4: Add the Heavy Cream
During the last 20 to 30 minutes of cooking, pour the 1 cup of heavy cream into the slow cooker. Stir gently to combine with the tomato sauce.
Cover and continue cooking until the cream is heated through and the sauce is smooth and creamy.
Step 5: Season and Serve
Season with salt and black pepper to taste. Remember that the tomatoes and garlic powder add some flavor, so taste before adding too much salt.
Serve the chicken and sauce over pasta, rice, or mashed potatoes, with extra sauce spooned over the top.
Variations & Tips
Use Fresh Basil
For the best flavor, use 2 tablespoons of fresh basil, chopped. Add it during the last 30 minutes of cooking or stir it in just before serving. Fresh basil adds a bright, aromatic note that dried basil can’t match.
Make It with Chicken Thighs
Substitute 4 boneless, skinless chicken thighs (or 6–8 small thighs) for the chicken breasts. Thighs are more forgiving and stay even juicier. Cooking time remains the same.
Make It with Sun-Dried Tomatoes
Add ¼ cup of chopped sun-dried tomatoes (packed in oil, drained) along with the diced tomatoes. Sun-dried tomatoes add intense, concentrated tomato flavor.
Add Onion and Garlic
For deeper flavor, add to the slow cooker:
-
½ cup diced onion (add with the chicken)
-
2–3 cloves fresh garlic, minced (add with the tomatoes)
Make It Spicy
-
Add ½ teaspoon of red pepper flakes
-
Add ¼ teaspoon of cayenne pepper
-
Use diced tomatoes with green chiles (like Rotel)
Make It with Parmesan
Stir in ½ cup of freshly grated Parmesan cheese along with the heavy cream. The Parmesan adds nutty, salty depth and helps thicken the sauce.
Make It with Spinach
Add 2 cups of fresh spinach during the last 10 minutes of cooking. Stir until wilted. The spinach adds color, nutrients, and a mild earthy flavor.
Make It with Mushrooms
Add 1 cup of sliced mushrooms to the slow cooker along with the tomatoes. Mushrooms add earthy depth and heartiness.
Make It Dairy-Free
-
Use full-fat coconut milk instead of heavy cream (adds a slight coconut flavor)
-
Use cashew cream (soaked cashews blended with water)
-
Omit the cream entirely — the dish will be more like a tomato-braised chicken (still delicious)
Make It in the Instant Pot
-
Use the “Sauté” setting to brown the chicken in oil (optional).
-
Add diced tomatoes, basil, and garlic powder.
-
Pressure cook on HIGH for 10 minutes (12 minutes for frozen chicken).
-
Quick release.
-
Remove chicken, then use the “Sauté” setting to stir in heavy cream and simmer until heated through.
-
Return chicken to the pot.
Make It in the Oven (No Slow Cooker)
-
Preheat oven to 375°F (190°C).
-
Place chicken in a 9×13-inch baking dish.
-
Add tomatoes, basil, and garlic powder.
-
Cover with foil and bake for 30–35 minutes.
-
Uncover, stir in heavy cream, and bake for another 5–10 minutes.
Storage & Reheating
Refrigerator: Store leftovers in an airtight container for up to 4 days. The sauce may thicken as it cools — that’s normal.
Reheating:
-
Microwave: 1–2 minutes per serving.
-
Skillet: Warm over medium-low heat, adding a splash of milk or broth if the sauce is too thick.
-
Slow cooker: Warm on LOW for 30–45 minutes.
Freezing: Cream-based sauces can separate when frozen. If you plan to freeze this dish, consider freezing before adding the cream. Add fresh cream when reheating. If you freeze the finished dish, thaw overnight in the refrigerator and reheat gently, stirring well to re-emulsify the sauce.
Frequently Asked Questions (FAQs)
Can I use chicken thighs instead of breasts?
Absolutely. Chicken thighs are more forgiving and stay even juicier. Use boneless, skinless thighs (about 1½ to 2 pounds). Cooking time remains the same.
Can I use milk instead of heavy cream?
Milk is not recommended. The acidity of the tomatoes can cause milk to curdle when cooked. Heavy cream has a higher fat content, which prevents curdling and creates a smooth, rich sauce. Half-and-half is a better substitute than milk, but heavy cream is best.
Why do I add the cream at the end?
Adding cream at the beginning can cause it to curdle or separate during the long cooking time. Adding it during the last 20–30 minutes ensures a smooth, creamy sauce.
Can I use fresh tomatoes instead of canned?
Yes. Use about 2 cups of fresh diced tomatoes. Roma or plum tomatoes are best because they have less water. You may need to add a splash of chicken broth if the sauce seems too dry.
What should I serve with this?
The creamy tomato sauce is begging to be soaked up. Great options include:
-
Pasta – Fettuccine, penne, or spaghetti
-
Rice – White, brown, or cauliflower rice
-
Mashed potatoes – Creamy and comforting
-
Crusty bread – For sopping up every last drop
-
Zucchini noodles – For a low-carb option
Can I add vegetables to this dish?
Yes. Add:
-
Sliced mushrooms – Along with the tomatoes
-
Chopped bell peppers – Along with the tomatoes
-
Fresh spinach – During the last 10 minutes
-
Zucchini – Diced, added during the last hour
Can I make this in advance?
Yes. Prepare the chicken and tomato mixture in the slow cooker, then refrigerate overnight. The next day, reheat gently on the stovetop or in the slow cooker, then stir in the cream at the end.

The Magic of Tomato and Basil
Tomato and basil is one of the most beloved flavor pairings in Italian cuisine. The bright, tangy acidity of tomatoes is perfectly balanced by the sweet, slightly peppery, aromatic notes of fresh basil.
In this slow cooker recipe, the tomatoes break down as they cook, creating a rich, savory base. The heavy cream mellows the acidity, transforming the sauce into something velvety and luxurious. The basil — whether dried or fresh — adds that signature Italian aroma.
This is the kind of sauce that tastes like it simmered all day on a stove in Tuscany. But thanks to the slow cooker, it requires almost no effort.
