Chicken breast is the most popular cut in Canadian kitchens, but overcooking it is the number one mistake home cooks make. The key is knowing exactly how long to cook chicken breast based on your method and the thickness of the meat.
Safe Internal Temperature
The single most important rule: chicken breast must reach an internal temperature of 74°C (165°F). Use an instant-read thermometer inserted into the thickest part. Remove from heat at 71°C (160°F) and let it rest — carryover cooking will bring it to safe temperature while keeping the meat juicy.
Cooking Times by Method
Oven-Baked Chicken Breast | Oven Temp | Thickness | Time | |-----------|-----------|------| | 200°C (400°F) | 2 cm (¾ in) | 18–22 min | | 200°C (400°F) | 2.5 cm (1 in) | 22–26 min | | 200°C (400°F) | 3 cm (1.25 in) | 26–30 min | | 190°C (375°F) | 2.5 cm (1 in) | 25–30 min |
Pro tip: Let chicken breast come to room temperature for 15 minutes before baking for more even cooking.
Stovetop / Pan-Seared Medium-high heat in a cast iron or stainless steel pan with a tablespoon of oil. Cook **6–8 minutes per side** for a standard breast. Press the centre — it should feel firm but still have slight give.
Grilled Chicken Breast Preheat grill to medium-high (200°C / 400°F). Grill **6–8 minutes per side**, rotating once for grill marks. Butterfly thick breasts or pound to even thickness for best results.
Air Fryer Set to 190°C (375°F). Cook **12–15 minutes**, flipping halfway. No need to preheat most air fryers.
Slow Cooker Cook on LOW for **3–4 hours** or HIGH for **1.5–2 hours**. Add ½ cup liquid (broth or water) to prevent drying out. Perfect for shredded chicken.
Instant Pot / Pressure Cooker Cook on HIGH pressure for **10–12 minutes** with 1 cup liquid. Use natural release for 5 minutes, then quick release. Fresh breasts need 12 minutes; frozen need 15–17 minutes.
Tips for Juicy Chicken Breast Every Time
- Brine it — Soak in salted water (1 tbsp salt per 4 cups water) for 30 minutes to 2 hours.
- Pound to even thickness — Use a meat mallet or rolling pin. Uneven thickness means uneven cooking.
- Don't skip the rest — Let chicken rest 5 minutes after cooking. This redistributes juices throughout the meat.
- Use a thermometer — Stop guessing. A $15 instant-read thermometer is the best investment for any kitchen.
- Don't overcrowd the pan — Leave space between pieces for proper searing.
