Salmon on sheet pan with shallots and olive oil poured on top.

Slow-Baked Salmon


Baking salmon at a low temperature results in super tender, flaky, buttery fish that is impossible to overcook and perfect for meal prep. If cooking salmon scares you, give this technique a try!


  • 1-2 lbs salmon, skin on or off
  • 1 small shallot, thinly sliced
  • 3 garlic cloves, thinly sliced or minced
  • 1 1/2 teaspoons salt
  • 1/2 teaspoon black pepper
  • 6 tablespoons olive oil
  • Optional: Lemon slices, fresh herbs (thyme, rosemary, dill, etc.), thinly sliced chilis


  1. Preheat oven to 300.
  2. Place 1-2lbs salmon on a lined baking sheet (I didn't add parchment paper for these photos, but normally I do!)
  3. Scatter 1 thinly sliced shallot and 3 thinly sliced or minced garlic cloves all over the salmon. If you are using any additional flavorings (see notes below), you can add them now as well.
  4. Season with 1 1/2 teaspoons salt and 1/2 teaspoon black pepper.
  5. Pour 6 tablespoons olive oil all over salmon. A good amount will run down the sides, so I like to take a spoon or brush and get some of that back on top of the salmon. 
  6. Bake for 25-30 minutes, or until salmon is just cooked and flakes easily. The time will depend on the thickness of your salmon, so just keep checking. If you have a meat thermometer, I like to go for 125F for salmon that is closer to medium than well-done.
  7. This salmon is delicious hot or cold and is perfect for meal prep!


Store leftover salmon in an airtight container in the fridge for up to a week.

You can make this slow-baked salmon with a whole piece of salmon or individual salmon filets - cooking time and technique will remain the same, but you might want to adjust the amount of olive oil a little!

This salmon is perfect for meal prep - see above for ways to use it throughout the week.
