Why this is a great keto dinner
Salmon provides high-quality protein and omega-3 fats, which are linked to heart and brain health. Broccoli and zucchini add fiber and volume with very few carbs. Avocado and olive oil bring healthy fats that make the meal satisfying. Read more about omega-3 foods.

Tips for perfect sheet pan salmon
- Start the vegetables first. Broccoli needs a few minutes longer than salmon.
- Pat the salmon dry so the seasoning sticks and the top roasts nicely.
- Do not overcook. Salmon continues to cook for a minute after you take it out.
- Use a hot oven. High heat gives caramelized vegetables instead of steamed ones.
Variations
- Garlic butter salmon: brush with melted butter, garlic and parsley instead of olive oil.
- Pesto salmon: spread a thin layer of pesto on top before roasting.
- Cajun salmon: season with smoked paprika, cayenne and garlic.
- Not keto? Add roasted sweet potato or serve with quinoa.
Meal prep
Roast a double batch and keep it in the fridge for up to 3 days. Cold salmon is delicious in a salad, like our Mediterranean salmon avocado salad. Add the avocado fresh when serving.

How much salmon should you eat?
Many dietary guidelines recommend about two servings of fish per week, ideally including fatty fish like salmon, sardines or mackerel. This sheet pan dinner is one of the easiest ways to make that a habit. Wild salmon is leaner with a stronger flavor; farmed salmon is milder and richer in fat. Both work well.
