I first tried this Slow Cooker Tuscan Chicken on a blustery weeknight and it immediately became a go-to. Tender chicken breasts slowly braised in a creamy, garlicky sauce with bright sun-dried tomatoes and wilted spinach — it feels decadent but cooks itself. This is the kind of dinner that impresses with minimal hands-on time, and it pairs well with pasta, rice, or a simple crusty loaf. If you enjoy set-and-forget chicken dishes, you might also want to compare this to my slow-cooker orange chicken for a different flavor profile: slow-cooker orange chicken copycat.

What you’ll need

Key ingredients and small notes:

4 boneless, skinless chicken breasts (about 1.5–2 pounds) — chicken thighs work if you prefer darker meat.
2 tsp Italian seasoning (store-bought or homemade)
½ tsp onion powder
Kosher salt and freshly ground black pepper, to taste
2 cloves garlic, minced (about 1 tsp)
½ cup sun-dried tomatoes, drained and chopped (packed-in-oil works great; if dry-packed, rehydrate in warm water)
½ cup chicken broth (or low-sodium broth)
1 cup heavy cream (or use half-and-half for a lighter sauce — see Variations)
½ cup grated Parmesan cheese (freshly grated gives the best texture)
1 cup baby spinach, roughly chopped

Step-by-step instructions

Follow these concise, user-friendly steps.

Season the Chicken:
- Pat chicken breasts dry. Rub each breast with Italian seasoning, onion powder, salt, and pepper.
Prepare the Slow Cooker:
- Place the seasoned breasts in the bottom of a 4-6 quart slow cooker in a single layer.
Make the Sauce:
- In a small bowl combine minced garlic, chopped sun-dried tomatoes, and chicken broth. Spoon this mixture evenly over the chicken.
Cook:
- Cover and cook on LOW for 3½–4 hours or on HIGH for 2–3 hours, until internal temperature reaches 165°F (74°C) and chicken is tender. Avoid overcooking; breasts can dry if left too long on HIGH.
Finish the Sauce:
- About 15–20 minutes before serving, remove the chicken to a plate. Stir the heavy cream and Parmesan into the slow cooker. Cover and let the sauce thicken for 10–15 minutes, stirring once.
Add Spinach:
- Stir the chopped baby spinach into the sauce until wilted. Return the chicken to the sauce and spoon the creamy mixture over each breast.
Serve & Enjoy:
- Plate the chicken with sauce and chosen sides. Taste and adjust salt and pepper.

Tip: If sauce is too thin, whisk 1 tsp cornstarch with 1 Tbsp cold water and stir into the hot sauce; cook 5–10 minutes until thickened.

Best ways to enjoy it

Serve this chicken spooned over:

Cooked pasta (fettuccine or penne) to soak up the sauce.
Creamy polenta or mashed potatoes for extra comfort.
A bed of cauliflower rice or quinoa for a lighter option.

For a complete weeknight plate, add a simple roasted vegetable or a crisp green salad. For inspiration on pairing slow-cooked chicken with starches and potatoes, see this hearty chicken cacciatore recipe: slow-cooker chicken cacciatore with potatoes.

Storage and reheating tips

Refrigerator: Cool leftovers to room temperature and store in an airtight container for up to 3–4 days.
Freezer: Freeze portions (sauce and chicken together) for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: Gently reheat on the stovetop over low heat or in the microwave at 50% power to avoid breaking the sauce. If sauce separates, whisk in a splash of cream or a teaspoon of butter while reheating.
Food safety: Always ensure reheated chicken reaches 165°F (74°C) before serving.

Helpful cooking tips

Browning: For extra flavor, quickly sear the seasoned chicken breasts in a hot skillet (1–2 minutes per side) before adding to the slow cooker. This isn’t required, but it adds a caramelized layer.
Sun-dried tomatoes: Use oil-packed sun-dried tomatoes for a rich texture; drain and chop. If using dry-packed, soak them in warm water for 10 minutes, then drain.
Cheese: Freshly grated Parmesan melts smoother than pre-grated varieties, which often contain anti-caking agents.
Thickening: Slow-cooker sauces can be thin; finish on the stovetop and reduce, or use a cornstarch slurry for quick thickening.
Low vs High: Cook on LOW when possible—it yields more tender chicken and better sauce integration.

Creative twists

Dairy-free: Substitute full-fat coconut milk for heavy cream and use nutritional yeast in place of Parmesan for a dairy-free sauce.
Add mushrooms: Stir in 6–8 ounces of sliced cremini mushrooms at the start for earthiness.
Protein swap: Use boneless skinless thighs—reduce cooking time slightly and check for doneness earlier.
Make it spicy: Add a pinch of red pepper flakes or a chopped roasted red pepper.
Lighter version: Use half-and-half or Greek yogurt (off-heat, tempered) instead of heavy cream—add yogurt at the end to prevent curdling.

Your questions answered

Q: Can I use frozen chicken breasts?
A: It’s best to thaw chicken first for even cooking and food safety. Cooking frozen chicken in a slow cooker can keep it in the “danger zone” (40–140°F) too long. Thaw overnight in the fridge before starting.

Q: How long does this take hands-on?
A: Active prep is about 10–15 minutes (seasoning and chopping). The slow cooker does the rest — 2–4 hours depending on setting.

Q: Can I make this ahead for company?
A: Yes. Cook the chicken, cool, and refrigerate (up to 24 hours). Reheat gently on low in the slow cooker or on the stovetop, add fresh spinach just before serving.

Q: Is there a low-fat substitute for heavy cream?
A: Use half-and-half for a lighter sauce; the texture will be less rich. If using a very low-fat milk, add a tablespoon of cornstarch to prevent a watery sauce.

Q: Why did my sauce separate?
A: Overheating or adding cold dairy directly to a very hot sauce can cause separation. Bring the sauce up to temperature first and then stir in cream; reheat gently.
