Slow Baked Salmon With Lemon, Herbs And Onion
This slow baked salmon recipe with lemon and onion features soft and silky salmon roasted at a low temperature and infused with the fragrance of lemon and herbs. It is a light and healthy way to enjoy this nutritious fish.
You only need 5 ingredients besides salt and pepper for this recipe. The preparation is minimal, making it a perfect choice for an easy yet delicious dinner. This dish also looks very lovely in my opinion with the light pink of the salmon complemented by the bright yellow lemon slices and the green herbs.
Slow And Gentle
Slow baking at a low temperature helps to retain the salmon’s natural moisture, resulting in a tender and silky texture. The gentle heat prevents the fish from drying out and ensures even cooking throughout the fillet. Besides, the longer cooking time allows the flavors of added ingredients, such as herbs, lemon, and onion as in this recipe, to permeate the salmon more deeply.
There are so many ways to cook salmon but this slow roasting method is still my most favorite. Though this method takes time (about 30-40 minutes), it doesn’t require constant attention. Simply place the salmon fillets in a baking dish, scatter lemon, herbs and onion slices over the top of the fish, cover and let them cook in the oven. You can freely use the roasting time to prepare other side dishes for the meal.
For a Mediterranean flair, you can simply add cherry tomatoes, olives and capers like in my Mediterranean baked salmon fillets.

Slow Baked Salmon With Lemon And Onion
Ingredients
- 1 lb salmon fillets (about 2-3 fillets)
- olive oil
- salt
- black pepper
- 1 small yellow onion or half a large onion, thinly sliced
- 1 lemon (and more for serving if desired)
- several sprigs of fresh thyme
Instructions
- Preheat your oven to 300โ (or 145-150โ).
- Massage the salmon fillets with olive oil and sprinkle salt and pepper generously over them. You may use ยพ – 1 teaspoon of salt per 1 lb of salmon. Set aside (it is best if you can give them time to become less cold).
- Reserve a quarter of the lemon and thinly slice the remaining.
- Spread a thin layer of onion slices in a baking dish to create a bed for the salmon to sit on. Place the salmon fillets on the onion bed, then scatter thyme leaves, lemon slices and the remaining onion slices on top of it. Squeeze the last lemon quarter all over.
- Cover the baking dish and then put it into the oven. Bake for about 30-40 minutes (more or less depending on how thick your fillets are) until the internal temperature reaches 125โ-130โ (52-54โ).
- Remove from the oven and serve with more lemon wedges on the side if desired.

Lovely. Only had a small fillet so I cut the time to 20 minutes.
