Oven-baked salmon and vegetables in 20 minutes: 34 g protein

Baked salmon has a reputation as a weekend project, yet it needs less oven time than chicken breast. With four fillets and whatever vegetables are in the fridge, the whole meal fits on a single tray. What follows are the exact quantities, the temperature, the steps and an estimate of what one serving gives you.

Prep time and servings

Prep: 8 minutes. Cooking: 12 minutes. Total: 20 minutes. Servings: 4.

The 20-minute figure only holds if the oven goes on before you pick up the knife. By the time it hits 220 °C, the chopping should already be done.

Ingredients

• 4 skinless salmon fillets, 150 g each (600 g total)
• 300 g cherry tomatoes, halved
• 300 g courgette, cut into 1 cm rounds
• 250 g peppers (2 medium), sliced into strips
• 200 g broccoli, cut into small florets
• 100 g red onion (1 medium), sliced
• 30 ml olive oil
• 2 garlic cloves, finely chopped
• 1 lemon (juice of half, the rest in wedges)
• 2 g dried oregano (about 1 teaspoon)
• salt and freshly ground black pepper, to taste

Method

1. Heat the oven to 220 °C (200 °C fan) and line a large tray with baking paper. The tray needs to be big enough for a single layer — crowded vegetables steam instead of roasting.
2. While it heats, cut the broccoli, courgette, peppers and onion. Keep the cherry tomatoes aside; they go in later.
3. Toss the vegetables (not the tomatoes) with 20 ml of the olive oil, the garlic, oregano, salt and pepper. Spread them out in one layer and roast for 6 minutes.
4. Meanwhile, pat the fillets dry with kitchen paper — a dry surface browns, a wet one poaches. Brush them with the remaining 10 ml of oil and season.
5. Pull the tray out, push the vegetables aside to make four gaps, scatter in the cherry tomatoes and sit the fillets in the spaces. Tuck the lemon wedges between them.
6. Return the tray to the oven for another 10 to 12 minutes. A 2.5 cm fillet is done at 10 minutes; a thicker cut wants roughly 2 minutes more.
7. Check it properly: the flesh should flake under a fork while the centre stays slightly pink and moist, around 55–60 °C. Dry, uniformly opaque salmon has had about three minutes too many.
8. Squeeze over the lemon juice, rest for 2 minutes, then divide between four plates along with the pan juices.

Nutrition per serving

These are an estimate per serving — one 150 g fillet plus a quarter of the vegetables and oil — worked out from the quantities above. Real values shift with how fatty the fish is.

• Calories: around 440 kcal
• Protein: 34 g
• Carbohydrate: 15 g
• Fat: 27 g

The fat number is high, but most of it comes from the salmon itself and the olive oil. If you track closely, the fish is the biggest unknown: farmed salmon can carry 20 percent more fat than wild.

Variations and swaps

If 440 kcal is too much for an evening meal, swap the salmon for the same weight of cod or hake. A serving then lands near 250 kcal with roughly 30 g of protein, and you should cut the second bake to 8–10 minutes, since white fish is thinner and dries out fast.

On a training day, add 150 g of potato or sweet potato per person, diced into 2 cm cubes. They go in 15 minutes before the vegetables and add about 115 kcal and 26 g of carbohydrate per serving. The same idea drives stuffed sweet potato with chicken, where the carbohydrate carries the meal rather than sitting beside it.

Skin-on fillets work fine — lay them skin down and count 30 to 40 kcal more per serving. Vary the vegetables by season: aubergine, thin carrot batons, cauliflower, sprouts. Anything dense goes in 5 minutes early.

For meal prep this keeps two days in the fridge, but reheat the salmon gently at about 150 °C for 6–7 minutes rather than blasting it. If you want something that survives three or four days in containers, rice with tuna and eggs is the better build. When fish is off the menu entirely, chickpea and feta salad gives the same meal structure from a plant protein.

When to see a doctor

Hives, swelling of the lips or throat and difficulty breathing after eating fish are not indigestion — that is a possible allergic reaction and needs emergency care. If you are pregnant or immunocompromised, avoid undercooked fish and bake the salmon until the centre is fully opaque. Ongoing digestive trouble, or eating around a diagnosed condition, is a conversation for a doctor or dietitian rather than a recipe page.

In short

Oven at 220 °C, vegetables alone for 6 minutes, then 10–12 minutes with the salmon on top. Four servings, roughly 440 kcal and 34 g of protein each, one tray to wash. Go lighter by switching to white fish, or heavier by adding potato to the same tray. For a breakfast built the same way — one pan, one protein source, whatever vegetables are open — scrambled eggs with vegetables and cheese follows the identical logic.
