The chicken sits in a little broth with garlic and sun-dried tomatoes, and for most of the cooking time the slow cooker looks quieter than you might expect. Then the lid comes off, the cream and Parmesan go in, and the liquid turns into the silky sauce that makes Crockpot Marry Me Chicken worth making. I like that the chicken gets its full cooking time before the dairy is added; the slow cooker does the steady work without asking you to babysit a pan.
The order matters here. The breasts cook with the tomatoes, garlic, and seasoning first, while the cream and finely grated Parmesan are saved for the finish. A smooth cornstarch slurry thickens the sauce during a short uncovered stretch, and fresh basil goes in right before serving. The result is tender chicken with a creamy, savory sauce, little bites of tomato, and just a gentle flicker of heat.

Kitchen Note
Stir the cornstarch and cold water until the mixture is completely smooth before it goes into the slow cooker. Any dry pockets will turn into little lumps instead of disappearing into the sauce.
Save Crockpot Marry Me Chicken for a cozy dinner with tender chicken, sun-dried tomatoes, and a creamy Parmesan sauce.
Why the Cream and Parmesan Go In After the Chicken
Slow cookers are good at keeping a covered pot gently cooking for hours, but that long stretch isn’t where I want the cream and Parmesan to spend their time. In this recipe, the chicken cooks first in broth with the garlic, tomatoes, and seasonings. Once the chicken is done, it comes out while the dairy is whisked into the hot cooking liquid. That timing gives you a creamy finish without asking the cheese to sit in the slow cooker for the entire cook.
There’s another practical reason to separate the stages: you get a chance to thicken the sauce before the chicken goes back in. The cornstarch slurry works during an uncovered cook on HIGH, so excess steam can escape while the sauce takes on a little body. It should stay spoonable, not turn into a stiff gravy. The chicken and its juices return at the end, which lets the meat pick up that finished sauce without extending its main cooking time.
This is also why I don’t try to make the slow cooker do every part at once. Give the chicken the covered cook, then finish the sauce with the dairy and slurry. That small change in sequence is what makes this version feel like a creamy skillet-style dish while keeping the hands-off ease of a crockpot dinner.
The Sun-Dried Tomatoes, Cream, and Parmesan Shape the Sauce

- Chicken breasts — Boneless, skinless breasts keep the dish straightforward to portion and fit neatly in a single layer. Choose pieces that are similar in size so they cook at a more even pace; the thickest part is the place to check for doneness.
- Oil-packed sun-dried tomatoes — Drain them and chop them before adding them around the chicken. They bring concentrated tomato flavor and a pleasantly chewy texture. Dry-packed tomatoes aren’t an exact swap here, since the recipe is built around the oil-packed kind.
- Chicken broth, garlic, and Italian seasoning — Broth gives the chicken a little cooking liquid, while minced garlic and Italian seasoning build the savory base. The broth doesn’t need to be a specialty product; the garlic is worth mincing fresh so its flavor spreads through the sauce.
- Heavy cream and finely grated Parmesan — Heavy cream gives the finished sauce its richness, and Parmesan adds salty, savory depth. Finely grated cheese blends more readily than large shreds. Milk isn’t a like-for-like replacement for the cream and can leave the sauce much thinner.
- Cornstarch and basil — Cornstarch gives the sauce a modest amount of thickness without a flour-based roux. Fresh basil brings a bright herbal note at the end, so chop it shortly before stirring it in rather than cooking it for the full slow-cooker time.
Cook the Chicken First, Then Finish the Sauce in the Crockpot
Season and Arrange the Breasts
Season both sides of the chicken with the kosher salt, black pepper, and Italian seasoning. Set the breasts in a single layer in a 6-quart slow cooker, leaving them arranged so the broth and aromatics can sit around them. Pour in the chicken broth, then add the drained, chopped sun-dried tomatoes, minced garlic, and red pepper flakes around the chicken. Keeping the chicken in one layer helps it cook evenly.
Let the Chicken Cook Covered
Cover the slow cooker and cook on LOW for 3 to 4 hours or on HIGH for 2 to 3 hours. The clock gives you a window, but the thickest part of each breast needs to reach 165°F before you move on. Check the larger pieces individually rather than assuming every breast is done at the same moment. If a piece hasn’t reached temperature, keep cooking and check it again.
Whisk and Thicken the Creamy Sauce
Transfer the cooked chicken to a plate, leaving the tomato and broth mixture in the slow cooker. Whisk in the heavy cream and Parmesan, then stir the cornstarch and cold water together until smooth and whisk that mixture into the sauce. Cook uncovered on HIGH for 15 to 25 minutes, until the sauce thickens slightly. It won’t become a dense gravy; look for a little more body than the broth had before the cream and slurry went in.
Return the Chicken for the Finish
Put the chicken back into the slow cooker along with any juices that collected on the plate. Stir in the chopped fresh basil so it disperses through the sauce. Cover the slow cooker for 5 minutes before serving, giving the chicken a brief rest in the finished sauce. Spoon the tomatoes and creamy sauce over each breast.
Two Ways to Adapt Crockpot Marry Me Chicken
Make the Sauce Milder
Leave out the red pepper flakes for a gentler sauce that still gets its savory character from the garlic, tomatoes, and Parmesan. The finished dish loses the little flicker of heat, but the creamy tomato base stays the same.
Adapt It for a Gluten-Free Table
Choose gluten-free-labeled chicken broth, Italian seasoning, sun-dried tomatoes, Parmesan, and cornstarch, then keep the rest of the ingredient list and method unchanged. The sauce stays creamy and the slow-cooker sequence doesn’t need to change.
Storage and Reheating
- Refrigerator: Store the chicken and sauce in a covered container for 3 to 4 days. The sauce may firm up when cold; it loosens as it warms.
- Freezer: Freeze the chicken with its sauce in an airtight freezer-safe container for up to 2 months. Thaw it in the refrigerator; the cream sauce may look a little less smooth after freezing.
- Reheating: Warm gently on the stovetop over low heat, stirring the sauce as it loosens, or use short microwave intervals. Avoid boiling the sauce, which can make its texture less smooth.
