Recipe at a glance
Prep time: 10–15 minutes
Cook time: 4–6 hours on LOW (or 2–3 hours on HIGH)
Total time: ~4–6 hours (mostly hands-off)
Yields: 4 servings
Difficulty: Easy — great for busy weeknights
Ingredients
4 boneless, skinless chicken breasts (about 1.5–2 lb / 680–907 g total)
1 cup chicken broth (240 mL)
1/2 cup grated Parmesan cheese (about 120 mL by volume)
2 teaspoons garlic powder (2 tsp = 10 mL)
2 teaspoons onion powder (2 tsp = 10 mL)
1 teaspoon dried thyme (1 tsp = 5 mL)
1 teaspoon dried basil (1 tsp = 5 mL)
1/2 teaspoon paprika (0.5 tsp = 2.5 mL)
Salt and freshly ground black pepper, to taste (start with 1/2 tsp salt)
1/2 cup heavy cream (120 mL)
2 tablespoons cornstarch (30 mL)
2 tablespoons water (30 mL)
1/4 cup chopped fresh parsley, for garnish (optional — 60 mL by volume)
Notes: If you prefer metric-only, the key liquid measures are 240 mL (broth) and 120 mL (heavy cream). Cornstarch slurry = 2 tbsp cornstarch + 2 tbsp water.
Equipment
4–6 quart slow cooker
Small bowl or measuring cup for slurry
Whisk or fork (to blend slurry)
Tongs or spatula for serving
Optional: skillet for quick sear (adds flavor)
Step-by-step directions
1) Prep (5–10 minutes)
Pat chicken breasts dry and season lightly with salt and pepper. If breasts are thick, you can butterfly or pound to even thickness for faster, even cooking.
Optional (recommended): Quickly sear the breasts in a hot skillet (1 minute per side) with a little oil to develop color and extra flavor. This step is optional — the slow cooker produces tender results without it.
2) Combine the flavor base (2 minutes)
In a bowl, whisk together the chicken broth (240 mL), grated Parmesan, garlic powder, onion powder, dried thyme, dried basil, paprika, and a few grinds of black pepper. Make sure the Parmesan is mixed so it doesn’t clump.
3) Slow cook (4–6 hours)
Place the chicken breasts in the slow cooker. Pour the Parmesan-broth mixture evenly over the chicken. Cover and cook:
LOW: 4–6 hours (best for tender, fall-apart texture)
HIGH: 2–3 hours (if short on time; check for doneness earlier)
Chicken is done when it reaches an internal temperature of 165°F (74°C) and is tender.
4) Finish with cream & thicken (30 minutes before serving)
About 30 minutes before serving, whisk together the heavy cream (120 mL), cornstarch (2 tbsp / 30 mL) and water (2 tbsp / 30 mL) until smooth. Pour the cream mixture into the slow cooker and gently stir so it combines with the cooking juices.
Cover and switch the slow cooker to HIGH (if it isn’t already) and cook for 20–30 minutes, until the sauce thickens and becomes glossy.
Alternate thickening: If you prefer a thicker sauce without cornstarch, remove the chicken and simmer the juices on the stove to reduce, then whisk in cream off-heat.
5) Serve
Spoon the creamy garlic-parmesan sauce over each breast. Garnish with chopped fresh parsley if desired. Serve hot.
Variations & Tips
Richer / juicier: Use bone-in chicken thighs (cook time will increase; check for doneness at 165°F / 74°C).
A little heat: Add 1/4–1/2 tsp red pepper flakes to the broth mixture.
One-pot meal: Add halved baby potatoes and baby carrots at the start — note cook time may increase slightly.
Low-carb: Serve over zoodles, cauliflower mash, or steamed broccoli.
Dairy-free option: Use full-fat coconut milk instead of heavy cream and nutritional yeast instead of Parmesan (flavor will change).
More Parmesan flavor: Stir in an additional 1/4–1/2 cup grated Parmesan right before serving.
Make-ahead, storage & reheating
Make-ahead: Assemble the chicken and broth mixture in the slow cooker insert, cover, and refrigerate up to 24 hours. Cook when ready.
Store: Refrigerate leftovers in an airtight container for 3–4 days.
Freeze: Freeze cooked chicken and sauce up to 2 months (thin sauce slightly on thawing; reheat gently).
Reheat: Warm gently in a skillet with a splash of broth or in a covered oven dish at 325°F (160°C) until heated through. Avoid high heat to prevent drying.
Serving suggestions & pairings
Creamy mashed potatoes or buttered egg noodles (classic)
Steamed rice or risotto to soak up the sauce
Roasted green beans, asparagus, or a crisp green salad to balance richness
Wine: Chardonnay or a light Pinot Grigio; non-alcoholic: sparkling apple cider
Troubleshooting
Sauce stays thin: Cook uncovered on HIGH for 15–20 minutes to reduce, or mix and add another 1 tsp cornstarch slurry.
Sauce too thick / gloopy: Whisk in 1–2 tbsp chicken broth or cream to loosen.
Chicken dry: Likely overcooked — next time check earlier and use an instant-read thermometer (165°F / 74°C target). Thicker breasts need a bit more time; thinner need less.
Grainy sauce: Whisk cornstarch slurry thoroughly before adding; add slurry gradually while stirring.
FAQ
Q: Do I need to sear the chicken?
A: No — searing adds flavor and color, but you’ll still get tender chicken without it.
Q: Can I use pre-grated Parmesan?
A: Yes — but freshly grated melts and blends into the sauce more smoothly.
Q: Is cornstarch the only thickener?
A: No — flour or a roux will work (make on stove), or reduce the sauce by simmering.
Q: Can I double the recipe?
A: Yes — use a larger slow cooker (6–8 quart) and check doneness; cooking time may increase slightly.
