How Cooking Affects the Calorie Count
The most significant factor influencing the calorie count of king prawns is the method of preparation. While raw prawns are a consistently low-calorie food, the addition of oils, sauces, or batter can drastically increase the caloric density.
Calorie Variations in Raw and Cooked King Prawns
- Raw King Prawns: A standard 100-gram serving of raw, peeled king prawns typically contains between 67 and 88 calories. This is a very lean source of protein, making it an excellent base for a healthy meal.
- Boiled or Steamed King Prawns: Minimal additional calories are added when boiling or steaming, making these some of the healthiest cooking methods. The final count will be very similar to raw prawns, with some variation due to water loss during cooking.
- Grilled or Sautéed King Prawns: A light coating of olive oil can add around 85-95 calories per 100 grams. The key to keeping this option healthy is using minimal oil and avoiding heavy marinades.
- Fried or Battered King Prawns: This method can dramatically increase calories due to the oil and batter. Deep-frying can push the calorie count to 200-250 calories per 100-gram serving, making it a much less diet-friendly option.

Health Benefits Beyond the Calorie Count
King prawns offer more than just a low-calorie profile. They are packed with essential nutrients that contribute to overall health. These benefits include:
- High-Quality Protein: Prawns are a complete protein source, providing all nine essential amino acids necessary for muscle repair and growth.
- Rich in Omega-3 Fatty Acids: Despite having low fat content, prawns contain a healthy amount of omega-3s, which are beneficial for heart health.
- Source of Important Vitamins and Minerals: They are a great source of selenium, a powerful antioxidant, as well as vitamin B12, iron, and zinc. Selenium supports immune function and protects cells from damage.
- Supports Bone Health: Key minerals like phosphorus, copper, and magnesium, which are found in prawns, are crucial for maintaining strong bones.
Tips for Cooking King Prawns Healthily
To enjoy king prawns without adding unnecessary calories, consider these preparation techniques:
- Steam Them: Steaming is one of the simplest and healthiest ways to cook prawns. Serve them with a squeeze of lemon and a sprinkle of fresh herbs for flavor.
- Grill or Barbecue: Marinate prawns in a light mixture of lime juice, chili flakes, and a dash of olive oil before grilling. This adds flavor without excessive calories.
- Create a Low-Calorie Stir-Fry: Toss prawns with plenty of vegetables and a light soy or ginger sauce. This adds bulk and nutrients while keeping calories low.
- Boil in a Flavorful Broth: Instead of plain water, boil prawns in a vegetable broth with herbs and spices. This infuses them with flavor while maintaining a low-calorie profile.
- Pair with High-Fiber Foods: Serve king prawns with brown rice, quinoa, or a large salad to create a balanced, filling, and low-calorie meal. Pairing them with other fiber-rich ingredients helps to keep you feeling full longer.
