Maintaining a healthy, balanced diet is essential for fitness enthusiasts, but it can sometimes feel like a chore when you’re juggling work, gym sessions, and personal life. That’s where seafood meal prep comes in, offering a simple, delicious, and nutritious way to fuel your body. Packed with protein, healthy fats, and essential nutrients, seafood makes the perfect base for easy, tasty meals that support your fitness goals. Whether you follow a keto, paleo, or another specialised diet, seafood meal prep ideas can be easily tailored to fit your needs.
Here are some fantastic seafood meal prep ideas to help you stay on track and enjoy a variety of flavours throughout the week.
1. Grilled Prawns with Cauliflower Rice
Grilled prawns are a versatile and protein-packed seafood dish that can be easily prepared in bulk. Pair them with cauliflower rice for a low-carb, nutrient-dense side that fits perfectly into keto or paleo meal plans. Simply marinate the prawns with a mix of olive oil, garlic, and lemon juice, and grill them until they’re golden and smoky. For the cauliflower rice, blitz cauliflower florets in a food processor until they resemble rice grains, then sauté them with a bit of olive oil, salt, and pepper. This dish is not only delicious but also incredibly easy to prepare for your seafood meal prep.
2. Baked Fish Fillets with Roasted Vegetables
Baking frozen fish fillets, such as barramundi or snapper, is an excellent way to save time while still enjoying a healthy seafood meal. These fish fillets are high in protein and omega-3 fatty acids, which are essential for muscle recovery and overall health. You can prepare the fish in a simple marinade made from lemon, herbs, and a dash of olive oil. Roast your favourite vegetables—think bell peppers, zucchini, or sweet potatoes—alongside the fish for a well-rounded meal. This easy seafood recipe is perfect for meal prep and can be stored in the fridge for a couple of days.

3. Seafood Stir-Fry with Broccoli and Bell Peppers
If you’re craving a bit of Asian-inspired flavour, a seafood stir-fry is a great way to mix things up. Use frozen prawns, squid, or even a combination of seafood for added variety. Stir-fry with a medley of colourful vegetables like broccoli, bell peppers, and carrots, and finish with a simple sauce made from soy sauce, garlic, and a touch of sesame oil. You can also use frozen mixed vegetables. This dish is not only quick to make but also a fantastic way to get your veggies in while enjoying your seafood meal prep.
4. Prawn and Avocado Salad
For those looking for a lighter option, a prawn and avocado salad is a refreshing and nutritious seafood dish. Combine cooked prawns with sliced avocado, mixed greens, cucumber, and cherry tomatoes. Toss everything together with a light lemon vinaigrette or olive oil dressing. This meal prep idea is perfect for those on the go and can be packed in containers for easy grab-and-go lunches throughout the week.

5. Seafood Soup with Zucchini Noodles
Soup is always a comforting and nutritious option, and adding seafood to the mix takes it to the next level. For a low-carb option, replace traditional noodles with zucchini noodles (also known as "zoodles"). Prepare a broth-based soup with your choice of fish, prawns, or mussels, and add vegetables like mushrooms, onions, and spinach for extra nutrients. The seafood adds a boost of protein and omega-3s, while the zucchini noodles keep the dish light yet filling. It’s perfect for those on a keto or paleo diet.

6. Seared Tuna with Asparagus and Sweet Potato Mash
If you’re craving a seafood meal that’s both hearty and nutritious, seared tuna is a perfect option. The tuna steaks are rich in protein and omega-3s, making them ideal for muscle repair and growth. Serve the seared tuna alongside a portion of steamed asparagus and a creamy sweet potato mash for a well-balanced and satisfying meal. This seafood meal prep idea is a great choice for those on specific diets like keto or paleo, as it’s both low in carbs and high in nutrients.
