Creamy, sun-dried tomato, Parmesan sauce with tender chicken — this is the recipe that earned its dramatic name. Rich without being heavy, deeply flavored from just a handful of ingredients, and the kind of dinner that makes people pause mid-bite.

Ten minutes of prep, the slow cooker takes it from there, and dinner is the kind of thing people talk about.

Ingredients

• 4 boneless skinless chicken breasts
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon Italian seasoning
• 3 cloves garlic, minced
• 1 cup chicken broth (240ml)
• 1 cup heavy cream (240ml)
• ½ cup grated Parmesan cheese (50g)
• ½ cup sun-dried tomatoes, chopped (70g)
• 1 tablespoon cornstarch (8g)
• 1 tablespoon cold water (15ml)
• Fresh basil, for serving

Step-by-Step Instructions

Step 1: Season the Chicken

Place the chicken breasts in the slow cooker. Season evenly with salt, pepper, garlic powder, and Italian seasoning — season both sides if you can, pressing the spices in slightly.

Step 2: Build the Sauce

Scatter the minced garlic and chopped sun-dried tomatoes over and around the chicken. Pour in the chicken broth and heavy cream. Sprinkle the grated Parmesan evenly over the top.

Step 3: Cook

Cover and cook on Low for 4–5 hours or High for 2–3 hours until the chicken is completely cooked through and tender. The cream and Parmesan will have melded into the broth and the whole slow cooker will smell incredible.

Step 4: Remove the Chicken

Carefully lift the chicken breasts out of the slow cooker and set aside on a plate. They’ll be very tender — handle gently to keep them intact.

Step 5: Thicken the Sauce

In a small bowl, whisk the cornstarch and cold water together until completely smooth. Stir the slurry into the sauce in the slow cooker. Return the chicken to the pot. Cover and cook on High for a further 15–20 minutes until the sauce thickens into a glossy, pourable cream sauce.

Step 6: Serve

Spoon the sauce generously over the chicken and garnish with torn fresh basil leaves. Serve immediately over pasta, mashed potatoes, rice, or alongside crusty bread.

Pro Tips

Use sun-dried tomatoes in oil, not dry-packed. Sun-dried tomatoes packed in oil are softer, more pliable, and release their flavor into the sauce more readily. Pat off excess oil before chopping. Dry-packed tomatoes can go tough during the long slow cook.

Don’t skip the cornstarch step. The liquid that comes out of the slow cooker after cooking is thin and watery — delicious, but not the silky sauce this dish is known for. The cornstarch slurry is what transforms it into something worth spooning over pasta and eating with a spoon.

Grate the Parmesan fresh. Pre-grated Parmesan from a tub is coated in anti-caking agents that don’t melt smoothly into a cream sauce. Freshly grated from a block melts beautifully and gives a much richer result.

Check chicken at the low end of the time range. Chicken breast can dry out if overcooked in a slow cooker. Check at 4 hours on Low — the chicken should be just cooked through and still juicy. A meat thermometer reading 165°F means it’s done.

Slice or shred — both work. This recipe is written for whole sliced breasts, but if the chicken has become very tender and wants to shred, that’s completely fine. Shredded in the sauce over pasta is also excellent.

Variations & Customizations

• Use chicken thighs — Boneless skinless thighs are juicier and more forgiving over a long cook. Use the same amount and the same cook time — they can also handle the upper end of the range without drying out.
• Add spinach — Stir a large handful of fresh baby spinach into the sauce when you add the cornstarch slurry. It wilts in 5 minutes and adds color and nutrition without changing the flavor.
• Add mushrooms — Slice 150g of cremini mushrooms and add them to the slow cooker with the other ingredients. They cook down and add an earthy depth that pairs beautifully with the cream sauce.
• Make it spicier — Add ½ teaspoon of red chili flakes to the seasoning for a subtle heat that works very well against the richness of the cream sauce.
• Add more Parmesan — Stir an extra handful of grated Parmesan into the sauce after thickening for an even more intensely cheesy result.
• Serve in wraps or sandwiches — Shred the chicken, toss in the sauce, and fold into warm flatbreads or ciabatta rolls for a completely different but equally good serving format.

Storage & Reheating

Method	Details
Fridge	Store chicken and sauce together in an airtight container for up to 4 days. The sauce keeps the chicken moist during storage.
Reheating	Warm gently in a covered pan over medium-low heat with a splash of broth or cream if the sauce has thickened too much, or microwave in short bursts. Avoid high heat which can cause the cream sauce to separate.
Freezer	Freeze in portions for up to 3 months. Thaw overnight in the refrigerator. Reheat gently on the stovetop — cream sauces can sometimes separate slightly after freezing but usually come back together with gentle heat and stirring.

Frequently Asked Questions

Can I use chicken thighs instead of breasts?

Yes — and many people prefer them for this recipe. Thighs are juicier and more forgiving over a long slow cook. They also shred beautifully into the sauce if you want to serve it that way. Use the same amount and timing.

Do I have to use sun-dried tomatoes?

They’re what gives this recipe its distinctive flavor and they’re worth finding. Without them the dish becomes a very good creamy garlic Parmesan chicken — still delicious, but a different recipe. If you can’t find them, roasted cherry tomatoes work as a substitute.

Can I make this ahead of time?

Yes. The sauce reheats very well. Make the full recipe, cool, and refrigerate. Reheat gently on the stovetop, adding a small splash of cream or broth to loosen the sauce. The flavor actually deepens overnight.

Can I double the recipe?

Yes, provided your slow cooker has enough capacity. A 6-quart slow cooker fits a doubled recipe comfortably. Cooking time stays roughly the same.

My sauce looks curdled or grainy. What went wrong?

High heat can cause the cream to separate — this sometimes happens if the slow cooker runs hot or if the sauce came to a rapid boil. Reduce the heat and stir gently. Adding a small splash of cold cream and stirring often brings it back together. Freshly grated Parmesan (not pre-grated) also helps prevent graininess.
