This crustless quiche is easy to make and is a great brunch, lunch, and even dinner dish. The fact that it is without a crust makes it gluten-free and low in carbohydrates, putting this delicious egg dish back on the menu for those with dietary restrictions or watching their carbs. There is minimal added salt and no processed ingredients, making it low in sodium as well.

The dish is also a great source of omega-3 fatty acids from the salmon and potentially the eggs if you use omega-3 eggs. Leeks add a natural sweetness and mushrooms and spinach add an earthy flavor. The dill and lemon zest add bright fresh elements that pair perfectly with the salmon.


  • 5.5 oz raw wild or sustainably farmed salmon fillets (yields approximately 4 oz or 3/4 cup flaked cooked salmon)
  • 2 tablespoons extra virgin olive oil
  • 1 leek, white and light green part only, halved and sliced thin (1/2 cup sliced)
  • 1 cup frozen chopped spinach, no salt added
  • 2 cups sliced white button mushrooms
  • 1/2 teaspoon salt
  • 5 large eggs
  • 1 cup whole milk
  • 2 tablespoons chopped fresh dill
  • Lemon zest


  1. Preheat oven to 375 F.

  2. To cook the salmon in the oven, place salmon fillets on a parchment lined baking sheet or saute pan. Drizzle with 1 tablespoon olive oil and bake at 375F for 10-15 minutes depending on thickness of the fillets. Alternatively, you can also poach the salmon.

  3. Meanwhile, add 1 tablespoon olive oil to large non-stick skillet and turn heat to medium. Add the sliced leek and stir to distribute evenly in the pan. When the leek begins to soften (about 1 minute), add the spinach and mushrooms. Season with 1/2 teaspoon salt and stir to combine. Saute on medium/medium-low for about 5 to 8 minutes until vegetables are tender and any liquid released from the vegetables has evaporated from the pan.

  4. When vegetables are cooked, remove from heat and set aside to let cool for a few minutes. When salmon is cooked, remove from oven as well and let cool before flaking with a fork.

  5. Meanwhile, in a bowl, blend the eggs and milk together with a whisk or blender. Season with a pinch of salt.

  6. Spray a pie plate or quiche dish with cooking spray such as avocado oil spray or olive oil spray. When vegetables are cooled to room temperature or slightly warm (but not hot), stir in flaked salmon and transfer mixture to the pie plate, spreading out into an even layer.

  7. Pour the egg mixture over the rest of the ingredients and sprinkle the top with the fresh dill.

  8. Bake for 45 minutes or until top starts to turn golden brown and center is cooked Start checking after 30 minutes—if it's getting too brown but the middle is too liquidy, cover with aluminum foil and continue to bake. The center can still be a little bit loose when done because it will finish cooking as it sits once you take it out of the oven.

  9. Once out of the oven, garnish with grated lemon zest before serving.

Ingredient Substitutions and Cooking Tips

  • Use a less expensive cut of salmon such as the tail end instead of a center cut piece since you are not presenting the fish as a whole fillet but are flaking it into pieces.
  • Add cheese for extra richness. Unlike most quiche recipes, this recipe does not call for cheese but if you want extra richness or creaminess, a mild cheese like goat cheese would make a great addition.
  • Cut back on on saturated fat in the recipe by replacing some of the whole eggs with more egg whites (for example, substitute 2 whole eggs with 4 egg whites) and use a reduced fat milk (but not skim milk) instead of whole milk.
  • Use smoked salmon instead of cooked fresh salmon for a more classic brunch dish however this will add a significant amount of salt so is not appropriate for a low-sodium diet plan.
  • Modify the vegetables to your taste. For example, if you want more of an earthy flavor, increase the mushrooms, or if you want a sweeter onion flavor, cut down on the spinach and increase the leeks. If you want to add some more carbohydrates, you can also substitute the mushroom with cooked diced or sliced potato which would pair very well with the salmon and leeks.
  • Modify the herbs for different flavor profiles or even based on what you have in your pantry or fridge! Other herbs such as dried oregano, thyme, fresh parsley, and chives pair just as well with salmon so feel free to swap out the dill and experiment with some others.


  • Leeks can contain a lot of dirt or sand in between each layer. The easiest way to clean them is to slice them in half lengthwise and hold each half under running cold water, fanning out the layers to make sure they are cleaned well.
  • To get an extra fluffy quiche, whisk eggs and milk extra vigorously or use an immersion blender to whip more air into the mixture.
  • To turn this into a firmer frittata-like dish, simply omit the milk and add 2-3 more eggs or egg whites.
