Why This Recipe

Salmon is on the nutrition calendar as a focus food from Day 5 onward. It is the highest-priority protein source in the recovery window for two reasons that compound each other. First: protein density. A 150 g fillet of Atlantic or sockeye salmon provides approximately 34 g of complete protein — all essential amino acids, high in leucine, which is the specific branched-chain amino acid that triggers muscle protein synthesis. At a body weight of ~87 kg and the lean mass preservation requirement for HIPEC candidacy, leucine-rich protein sources matter more than generic protein sources. Second: EPA and DHA. Salmon is among the highest dietary sources of eicosapentaenoic acid and docosahexaenoic acid — the long-chain omega-3 fatty acids with documented anti-inflammatory effects. The mechanism relevant here is inhibition of the COX-2 pathway, which is the same inflammatory pathway implicated in colorectal cancer progression. Two servings of salmon per week is a consistent recommendation across oncology nutrition literature for this reason. The fat in salmon (~13 g per 150 g fillet) is the type worth having — predominantly unsaturated, and the specific fatty acid profile that makes it therapeutically valuable. This is different from the fat in cheese, cream, or fried food. Days 5+ is when the gut has stabilised enough to handle it.

What to Buy

Atlantic salmon or sockeye salmon are the most accessible options with consistent omega-3 profiles. Farmed Atlantic salmon typically has a higher total fat content; wild sockeye is leaner with a slightly stronger omega-3 ratio. Either is appropriate. Avoid during the cycle:

• Smoked salmon — cured with salt, often high sodium, and the smoking process can produce compounds that are an unnecessary variable during chemotherapy
• Canned salmon in oil — the oil is usually sunflower or soybean, high in omega-6. Use water-packed canned salmon if canned is the only option.
• Sashimi or raw preparations — immunosuppression during the cycle makes raw fish a pathogen risk

Canned salmon (water-packed) is a legitimate option for Days when cooking feels like too much. It is not the same quality, but ~25 g protein per 100 g and meaningful omega-3 content — eat it cold with white rice or crackers.

Ingredients

• 1 salmon fillet, 150–180 g, skin-on (skin holds the fillet together during cooking and is edible)
• Small amount of olive oil — 1 tsp, brushed on. Not optional from Day 5; the fat is part of what makes this recipe work.
• Salt and black pepper
• 1 lemon — juice and zest (optional but recommended: citric acid helps cut the richness)
• 1–2 garlic cloves, minced or sliced (Day 5 onward — garlic is cleared by this point)
• Fresh or dried dill, or fresh parsley (optional)

Method

Step 1 — Bring to room temperature
Remove salmon from the refrigerator 15 minutes before cooking. Cold salmon straight into the oven cooks unevenly — the outside overcooks before the centre reaches temperature. This is the most commonly skipped step and the most common reason salmon is dry.

Step 2 — Preheat oven
180°C (350°F). Not higher. The low-temperature method keeps the salmon moist. High heat (220°C+) produces a firmer, drier result that is harder to eat, particularly if appetite is already reduced.

Step 3 — Season
Pat the fillet dry with kitchen paper — moisture on the surface causes steaming rather than roasting. Brush with 1 tsp olive oil. Season with salt, pepper, and lemon juice. Add minced garlic on top if using. A few slices of lemon on top help regulate moisture during cooking.

Step 4 — Bake
Place skin-down on a baking tray lined with parchment paper. Bake for 12–15 minutes depending on thickness (a standard 150 g fillet at 2.5 cm thick takes 12–13 minutes at 180°C). The salmon is done when it flakes easily with a fork at the thickest part but the centre is still slightly translucent — it continues to cook after leaving the oven. Do not wait for it to look fully opaque; by then it is overcooked.

Step 5 — Rest briefly
Let it rest 2 minutes before eating. The centre finishes cooking from residual heat.

Alternative: En Papillote (In Parchment)

Place salmon on a sheet of parchment paper. Add lemon slices, garlic, fresh dill, and a splash of white wine or water. Fold the parchment into a sealed parcel. Bake at 180°C for 15–18 minutes. The steam inside the parcel keeps the fish moist even if left an extra 2–3 minutes. This method is more forgiving than open baking and produces a softer texture — useful if appetite is uncertain.

What to Serve With It

Days 5–7:

• White rice or mashed potato — low-fiber, easy starch base
• Steamed courgette or soft-cooked carrot — reintroduced vegetables at this point in the cycle
• Bone broth on the side — hydration, gelatin, gut lining support

Days 8–13:

• Steamed broccoli or broccolini (cruciferous reintroduction window, Day 8+)
• Roasted asparagus or green beans
• Lentils alongside for additional plant protein
• Avocado (half — potassium, healthy fat; monitor against other potassium sources)

Frequency

Two servings per week is the target established by the nutrition calendar — sufficient to maintain meaningful omega-3 intake without exceeding what is practical or causing mercury accumulation concerns (salmon is a low-mercury species, so this is not a binding constraint at two servings, but is worth noting for context). In a 14-day cycle, two servings per week means 4 servings total, all in the Days 5–13 window. That works out to roughly every other day in the second half of the cycle.

Fitting Into the Day

A 150 g salmon fillet at lunch provides 34 g protein. On a Day 7 stack:

• Morning whey shake: 25 g
• Soft-scrambled eggs (breakfast): 18 g
• Greek yogurt (mid-morning): 20 g
• Baked salmon (lunch): 34 g → running total: 97 g by early afternoon

That leaves 23–33 g for dinner, which is a small protein requirement — a portion of lentil soup (18 g) plus a small chicken addition covers it.
