Ingredients
For the Salmon:
- 1–1½ pounds salmon filet
- 1 tablespoon olive oil
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon paprika (optional, for color)
- 1 teaspoon lemon juice (optional but recommended)
For the Dill Mayo Topping:
- ½ cup mayonnaise
- 1–2 tablespoons fresh dill (or 1–2 teaspoons dried dill)
- ½ teaspoon garlic powder
- Pinch of salt
Instructions
- Preheat oven to 375°F. Line a baking sheet with parchment paper.
- Pat the salmon dry and place it on the prepared baking sheet.
- Drizzle with olive oil and season with salt, pepper, garlic powder, and paprika. Add a small squeeze of lemon juice if using.
- In a small bowl, mix together mayonnaise, dill, garlic powder, and a pinch of salt.
- Spread the dill mayo evenly over the top of the salmon.
- Bake for 12–18 minutes, depending on thickness. The salmon is done when it flakes easily with a fork and reaches about 125–130°F internally.
Let rest for a few minutes before serving.
How to Make Easy Keto Tartar Sauce
If you’d rather serve this salmon with a dipping sauce instead of baking the mayo on top, here’s a quick homemade keto tartar option.
Option 1: Classic Style
- ½ cup mayonnaise
- 1–2 tablespoons finely chopped pickles
- 1 teaspoon pickle juice
- ½ teaspoon dill
- Pinch of salt
Stir together, refrigerate, and store in airtight container until ready to serve.
Option 2: Dill Relish Shortcut
For an even quicker version, simply mix:
- ½ cup mayonnaise
- 1–2 tablespoons dill relish
That’s it. The relish already contains the tang and seasoning, making this version extra simple.
