Fish is an exceptionally lean protein source rich in omega-3 fatty acids, which play a role in reducing exercise-induced inflammation and supporting recovery. It digests quickly, making it an excellent choice around workouts. Each serving of Mediterranean Baked Sea Bass delivers 36g of protein at 340 calories — that's 9 calories per gram of protein, making it one of the more efficient protein sources on this site. Protein accounts for roughly 42% of total calories in this dish. With only 8g of carbohydrates per serving, this recipe fits well into low-carb, ketogenic, or carb-cycling approaches. The 18g of fat primarily comes from the cooking method and protein source itself, contributing to satiety and supporting fat-soluble vitamin absorption.
Mediterranean Baked Sea Bass is a straightforward recipe that scales well for meal prep. This recipe makes 4 servings, each delivering 36g of protein and 340 calories — ideal for tracking macros across the week. Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, warm gently on the stovetop over medium-low heat or in the microwave in 90-second intervals, stirring between each, until heated through. Adding a small splash of water or broth prevents the protein from drying out during reheating. Mediterranean Baked Sea Bass also freezes well — portion into individual freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating. Batch cooking a double or triple portion on the weekend means you have 36g-protein meals ready throughout the week with zero daily effort.
Fish is best cooked fresh. You can prep the marinade or sauce 1-2 days ahead. Cooking takes under 15 minutes, so day-of prep is the practical choice.
Yes — any firm-fleshed fish works. For flaky white fish recipes, try cod, halibut, or mahi-mahi. For salmon recipes, try arctic char or steelhead trout.
Use a meat thermometer for proteins: chicken 74°C (165°F), beef medium 60°C (140°F). For baked dishes, look for golden brown on top and bubbling around the edges.
