Pan-Seared Sea Bass with Lemon Fennel Sauce: 42g Protein Per Serving
If you’re serious about body composition, fish needs to be a staple in your rotation. Sea bass delivers exceptional protein density with minimal calories, making it one of the most efficient foods for preserving muscle while cutting fat. This recipe combines lean protein with metabolism-supporting compounds in fennel and lemon—no complicated techniques required.
Why Sea Bass for High-Protein Nutrition
Sea bass is a white fish packed with 25g of protein per 100g serving. Unlike fattier fish, it delivers clean protein without excess calories, which means you can eat satisfying portions while staying in a deficit. It’s also rich in selenium and B vitamins, which support thyroid function and metabolic rate—two things that matter when you’re optimizing body composition.
Ingredients (Serves 2)
- 2 sea bass fillets (6-7 oz each, skin-on)
- 2 tbsp extra virgin olive oil
- 1 medium fennel bulb, thinly sliced
- 2 cloves garlic, minced
- 1 lemon (juice and zest)
- ½ cup low-sodium fish or vegetable broth
- ¼ cup dry white wine (optional, can substitute with broth)
- 1 tsp fennel seeds
- Sea salt and black pepper to taste
- Fresh parsley for garnish
- Lemon slices for plating
Step-By-Step Instructions
Step 1: Prep Your Ingredients
Slice the fennel bulb lengthwise, then into thin half-moons. Reserve some of the fronds for garnish. Zest the lemon before cutting it in half, then juice both halves. Mince your garlic and measure out the broth and wine.
Step 2: Season the Fish
Pat the sea bass fillets dry with paper towels—this is crucial for achieving a proper sear. Season both sides generously with sea salt and black pepper. Let them sit for 2-3 minutes while you heat your pan.
Step 3: Sear the Sea Bass
Heat 1 tbsp olive oil in a large skillet over medium-high heat until shimmering. Place fillets skin-side down and sear for 4-5 minutes without moving them. The skin should crisp up and turn golden. Flip and sear the flesh side for 2 minutes. Transfer to a plate.
Step 4: Build the Fennel Base
In the same pan, add the remaining olive oil. Sauté sliced fennel over medium heat for 4-5 minutes until slightly softened and caramelized at the edges. Add minced garlic and fennel seeds, cooking for 30 seconds until fragrant.
Step 5: Deglaze and Simmer
Pour in the white wine (if using) and scrape up any browned bits from the pan. Add the broth and lemon juice, then return the sea bass fillets to the pan skin-side up. Reduce heat to medium-low and simmer gently for 3-4 minutes, allowing the fennel to finish cooking and the sauce to reduce slightly.
Step 6: Finish and Plate
Remove from heat and stir in the lemon zest. Taste and adjust seasoning with salt and pepper. Plate each fillet with fennel on the side, spoon sauce over the top, and garnish with fresh parsley and reserved fennel fronds. Add a lemon slice for visual appeal.

Pro Tips for Maximum Results
Meal Prep Strategy: Cook the fennel base in bulk and store separately from the fish. Pan-sear fillets fresh each time—takes only 7 minutes. Properly cooked fish tastes better and maintains texture far better than reheated versions.
Storage: Refrigerate cooked fish for up to 3 days in an airtight container. The sauce keeps well, making assembly simple for weekday meals. Don’t freeze—fresh or properly refrigerated is optimal.
Portion Flexibility: For aggressive fat loss, pair with roasted broccoli or cauliflower (minimal additional calories). For maintenance or muscle gain, add a serving of white rice or sweet potato alongside (adds 40-50g carbs). The 42g protein serves as your anchor across all goals.
Substitution Options: Halibut, cod, or haddock work identically. Thicker cuts may need 1-2 additional minutes per side. Frozen fillets work fine—thaw fully and pat dry before cooking.
Fennel Benefits: Beyond flavor, fennel contains compounds that support digestive health and may help reduce bloating—useful when you’re monitoring body composition closely. The natural sweetness keeps the dish satisfying without added sugars.
Bottom Line
This isn’t complicated cooking. It’s strategic protein intake designed for men who care about what their body looks like. 42g of protein, under 300 calories, ready in 20 minutes, and it tastes like you actually put effort in. That’s the formula.
