Slow-cooker Tuscan Garlic Chicken is the kind of weeknight recipe that feels indulgent without the fuss. Tender chicken breasts simmer in a garlicky, sun-dried tomato–spiked sauce that finishes silky with heavy cream and bright spinach. It’s ideal when you want a hands-off dinner that still tastes like you spent time in the kitchen. If you’re a fan of easy slow-cooker chicken dinners, you might also enjoy a sweeter-savory variation like Slow Cooker Brown Sugar Garlic Chicken, which uses similar set-it-and-forget-it convenience with a different flavor profile.

Why you’ll love this dish

This recipe checks a lot of boxes: minimal hands-on time, family-friendly flavors, and a sauce that doubles as a spoonable topping for rice or pasta. The slow cooker coaxing turns otherwise lean chicken breasts into tender, juicy pieces without constant attention. It’s also forgiving — you can scale it up for a crowd or halve it for two.

“A creamy, garlicky comfort dinner that comes together while you run errands — one of my go-to slow-cooker meals.” — home-cook review

Good occasions for this recipe:

Busy weeknight dinners when you want a comforting, nutritious meal with minimal cleanup.
Casual dinner parties or potlucks — the sauce stays warm and tasty in the slow cooker.
Meal prep: it reheats well and makes a great protein for lunches.

Step-by-step overview

This dish is straightforward: season and layer the chicken, pour in a seasoned broth and sun-dried tomato mixture, then let the slow cooker do the work. Near the end you’ll fold in spinach, stir in cream to finish the sauce, and grate Parmesan on top before serving. If you like predictable timing, plan for 6–7 hours on low or 3–4 hours on high.

What you’ll need

4 boneless, skinless chicken breasts (about 1.5–2 lb)
1 cup low-sodium chicken broth
1 cup sun-dried tomatoes, chopped (oil-packed or rehydrated dry-packed)
3 cups fresh spinach, loosely packed
4 cloves garlic, minced
1 tsp Italian seasoning
Salt and freshly ground black pepper, to taste
1 cup heavy cream
Grated Parmesan cheese for serving

Substitution notes:

Use half-and-half instead of heavy cream for a lighter sauce, but it will be thinner.
Swap kale for spinach — sauté or shave it thin first so it wilts well in the cooker.
If sun-dried tomatoes are oil-packed, drain them slightly to avoid a greasy sauce.

Step-by-step instructions

Lightly season both sides of the chicken breasts with salt and pepper. Place them in a single layer in the slow cooker.
In a medium bowl, whisk the chicken broth, chopped sun-dried tomatoes, minced garlic, Italian seasoning, and a pinch of salt and pepper. Pour the mixture evenly over the chicken.
Cover and cook: low for 6–7 hours or high for 3–4 hours. The chicken is done when an instant-read thermometer reads 165°F at the thickest part and the meat is tender.
About 30 minutes before the end of cooking, add the fresh spinach and gently stir so it wilts into the sauce.
With about 5 minutes remaining, stir in the heavy cream until the sauce is smooth and heated through. Taste and adjust seasoning with salt and pepper as needed.
Serve hot, spooning the creamy tomato-spinach sauce over each piece and topping with grated Parmesan.

Cooking safety tip: always confirm doneness with a thermometer — chicken thickness varies and visual cues can be misleading.

Best ways to enjoy it

Serve this chicken over:

Cooked pasta (fettuccine or penne) to soak up the sauce.
Mashed potatoes or creamy polenta for an especially cozy meal.
Steamed rice or cauliflower rice for a lower-carb option.

For an easy weeknight twist, shred the chicken and assemble into warm tortillas with extra sauce, lettuce, and a sprinkle of Parmesan — you can borrow ideas from cheesy handhelds like Cheesy Garlic Chicken Wraps to turn leftovers into satisfying lunches. Finish plates with fresh lemon zest or a few basil leaves to brighten the dish.

Storage and reheating tips

Refrigeration: Cool leftovers to room temperature (no longer than 2 hours at room temp), then store in an airtight container for up to 3–4 days.
Freezing: Freeze portions in freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating. Texture of spinach may be softer after freezing.
Reheating: Reheat gently in a skillet over medium-low heat with a splash of broth or a tablespoon of cream to loosen the sauce. Microwave in short bursts, stirring between intervals, until evenly heated. Always reheat to 165°F.

Food safety: Do not refreeze once thawed. Discard any leftovers kept more than four days in the refrigerator.

Helpful cooking tips

Even cooking: If breasts vary greatly in size, pound thicker pieces to even thickness so they finish at the same time.
Flavor boost: Sauté the minced garlic briefly in a tablespoon of olive oil before adding to the broth mix for a slightly mellower garlic flavor.
Texture: For a thicker sauce, remove the chicken at the end, stir in cream and simmer the sauce on high (slow cooker or stovetop) uncovered for 5–10 minutes, then return the chicken.
Sun-dried tomato tip: If using dry-packed sun-dried tomatoes, rehydrate them in warm water for 10 minutes, drain, then chop. This gives more melon-like tenderness and releases flavor into the sauce.

Creative twists

Lemon-Garlic Tuscan: Add 1 tbsp lemon juice and zest when stirring in the cream for brightness.
Keto swap: Replace pasta or rice with cauliflower mash and use heavy cream as written for a low-carb, high-fat version.
Vegetarian version: Substitute firm tofu or large portobello caps for chicken and cook until heated through; adjust seasoning and cook time accordingly.
Protein swap: Use boneless skinless thighs for more fat and richness; they’ll stay tender and tolerate longer cook times.

Common questions

Q: Can I use frozen chicken breasts?
A: Yes, but it changes cooking dynamics. Thawed chicken gives the most reliable timing and even cooking. If you must use frozen, increase cook time and ensure the internal temperature reaches 165°F. For safety and best texture, thaw in the refrigerator overnight first.

Q: Can I omit the cream?
A: Yes. Omitting the cream yields a lighter, brothier tomato-spinach sauce. To keep some richness without heavy cream, stir in 2–3 tbsp of cream cheese or a splash of half-and-half at the end.

Q: Will this work in an Instant Pot or pressure cooker?
A: You can adapt it. Use the sauté function to combine ingredients if desired, then pressure cook on high for about 8–10 minutes for thawed breasts, followed by a natural release for 5 minutes. Add spinach and cream after cooking and use the sauté mode briefly to wilt and finish the sauce.

Q: How can I make it gluten-free?
A: The recipe is naturally gluten-free if you use gluten-free chicken broth and ensure any added condiments are labeled gluten-free. Serve over gluten-free pasta or rice.

Q: Is this recipe meal-prep friendly?
A: Yes. Portion into meal containers with a starch (rice, pasta, or potatoes) and refrigerate up to 4 days. Reheat gently, adding a splash of broth to refresh the sauce.
