Chicken Breast Nutrition 100g: Calories & Macros

Chicken breast is a staple lean protein prized for its mild flavor and versatility. This article breaks down the exact nutritional profile of a 100g serving of cooked chicken breast, explaining what those numbers mean for your daily diet and how to prepare it to keep it juicy and flavorful. Whether you’re meal-prepping or just curious, this guide gives you the facts and the cooking know-how.

Ingredients

  • 1 boneless, skinless chicken breast (about 6 oz / 170 g raw, yields ~4 oz / 115 g cooked)
  • 1 tsp (5 ml) olive oil (optional, for pan-searing)
  • Salt and black pepper to taste
  • 1/2 tsp (1 g) garlic powder (optional)
  • 1/2 tsp (1 g) paprika (optional)

Instructions

  1. If the chicken breast is thick (over 1 inch / 2.5 cm), place it between two sheets of plastic wrap and gently pound to an even thickness of about 3/4 inch (2 cm). This ensures even cooking.
  2. Pat the chicken dry with paper towels. Season both sides with salt, pepper, and any optional spices like garlic powder or paprika.
  3. Heat a skillet over medium-high heat. Add the olive oil if using, and swirl to coat the pan.
  4. Place the chicken in the skillet. Cook for 5–7 minutes without moving it, until the bottom is golden brown.
  5. Flip the chicken. Reduce heat to medium. Cook for another 5–7 minutes, until the internal temperature reaches 165°F (74°C) as measured with a food thermometer inserted into the thickest part (USDA FSIS safe minimum).
  6. Transfer the chicken to a cutting board and let rest for 5 minutes before slicing. This allows juices to redistribute.

Tips

  • Weigh after cooking: The 100g nutrition figures refer to cooked, skinless breast meat. Raw chicken weighs more due to water content; 100g raw yields about 75g cooked.
  • Don’t overcook: Chicken breast dries out quickly. Use a thermometer and pull it off the heat at 165°F (74°C) – no higher.
  • Substitute: No olive oil? Use any neutral oil or a nonstick pan with cooking spray. You can also bake at 400°F (200°C) for 18–22 minutes.
  • Common mistake: Slicing immediately after cooking. Resting is non-negotiable for juiciness.

Serving Suggestions

Serve sliced chicken breast over a fresh green salad, alongside roasted vegetables and quinoa, or in a whole-grain wrap with hummus and crunchy lettuce. It also pairs well with rice and steamed broccoli for a classic balanced plate.

Variations

Lemon-Herb: Add 1 tbsp (15 ml) lemon juice and 1 tsp (1 g) dried thyme to the seasoning. Spicy: Add 1/2 tsp (1 g) cayenne pepper and a pinch of chili flakes. Marinated: Soak the raw breast in 1/4 cup (60 ml) buttermilk for 30 minutes before cooking for extra tenderness (pat dry before seasoning).

Storage and Reheating

Refrigerate cooked chicken in an airtight container within 2 hours of cooking. It will keep for 3–4 days. To reheat, place slices in a skillet over medium-low heat with a splash of broth or water, covered, for 5–7 minutes, or microwave in 30-second bursts until hot. Avoid overcooking during reheating to prevent dryness.

Frequently Asked Questions

How many calories are in 100g of cooked chicken breast? A 100g serving of cooked, skinless chicken breast contains approximately 165 calories. This can vary slightly depending on cooking method and whether any oil is added.

How much protein is in 100g of chicken breast? About 31g of protein per 100g cooked. This makes it an excellent source of high-quality, complete protein.

Is chicken breast low in fat? Yes, it is very lean. A 100g serving has about 3.6g of fat, most of which is unsaturated, especially if you remove the skin.

Does the nutrition change if I eat the skin? Yes, the skin adds significant calories and fat. With skin, 100g cooked has about 200 calories and 10g fat. Removing the skin before cooking keeps it leaner.

Can I use frozen chicken breast? Yes, but thaw it completely in the refrigerator before cooking. Cooking from frozen increases the time and can lead to uneven doneness.

Why is my chicken breast always dry? Overcooking is the main culprit. Always use a meat thermometer and remove from heat at exactly 165°F (74°C). Also, resting the meat for 5 minutes helps retain juices.
