Ingredients Needed

- 2 salmon fillets
- 1 cup avocado, chopped
- ¼ cup red onion, chopped
- ½ cup cherry or grape tomatoes, chopped
- 1 garlic clove, crushed
- ½ jalapeno pepper, finely minced
- a squeeze of lime juice
- ¼ cup cilantro leaves, chopped
Ingredient Notes & Substitutions
Salmon: Opt for high-quality salmon fillets. Fresh is always best, but frozen (thawed properly) works too. For the US market, Sockeye salmon is a great choice for its rich flavor and vibrant color. Wild-caught salmon is generally considered healthier and more flavorful than farmed.
Avocado: Choose a ripe avocado that yields to gentle pressure. You can also try the stem test: if the stem comes off easily and the flesh underneath is green, it’s ripe.
Jalapeno: Adjust the amount of jalapeno to your spice preference. Remove the seeds and membranes for a milder flavor. If you prefer a different flavor profile, try Serrano or Poblano peppers. Serranos will be hotter, while Poblanos are milder and slightly sweet.
Dairy-Free: This recipe is naturally dairy-free, making it suitable for those with dairy sensitivities or following a dairy-free keto diet.

How to Make Romantic Keto Salmon with Avocado Salsa
Step 1: Marinate the Salmon
Combine lime zest, garlic, smoked paprika, salt, and pepper in a small bowl. Rub the mixture all over the salmon fillets. Let the salmon marinate for at least 30 minutes. The aroma of the lime zest and smoked paprika is already making my mouth water!
Step 2: Prepare the Avocado Salsa
While the salmon is marinating, prepare the avocado salsa. Chop the avocado, red onion, cherry or grape tomatoes, garlic, jalapeno, and cilantro. Gently mix all the ingredients together in a bowl. Squeeze about half of a lime over the salsa and gently mix again. The vibrant colors of the salsa are so appealing!
Step 3: Cook the Salmon
To get the salmon cooking, get out a saute pan and heat to medium high heat. Add a little bit of butter to the pan and then take the salmon fillet and season with salt and black pepper. The butter should melt quickly and start to sizzle.
Step 4: Sear the Salmon (First Side)
Add your salmon skin side up to the melted butter in the hot pan. Turn the heat down to medium. Cook for about 3-5 minutes until you see that they are cooked about ⅓ of the way up the fish from the bottom. The sizzle of the salmon hitting the hot pan is music to my ears!
Step 5: Sear the Salmon (Second Side)
Flip the filets and cook the other side for another 3-5 minutes or until almost cooked through. I like to keep the center a little pink. When you set them aside for a few minutes to rest they will continue to cook a little. (Note cooking time may vary depending on the size of your fillets.) The internal temperature of the thickest part of the salmon should be between 125°-135°F for medium rare and 145°F for well done.
Step 6: Serve
Serve the avocado tomato salsa on top or on the side of the salmon. I like to garnish with extra cilantro and a lime wedge for a pop of color and freshness. The contrast between the warm salmon and the cool salsa is delightful!
Different Cooking Methods for Salmon
While pan-searing is my go-to for this recipe, there are other ways to cook salmon. Here are some alternatives:
Pan Searing: As detailed above, this method is quick and yields a crispy skin. Make sure your pan is hot before adding the salmon.
Grilling: Preheat your grill to medium-high heat (around 400°F). Lightly oil the grates to prevent sticking. Grill the salmon for about 4-5 minutes per side, or until cooked through. A little lemon juice can help keeping the salmon from sticking.
Baking: Preheat your oven to 400°F (200°C). Place the salmon fillets on a baking sheet lined with parchment paper. Bake for 12-15 minutes, or until cooked through. This is a convenient option when you want a hands-off approach.
Air Frying: Preheat your air fryer to 400°F (200°C). Place the salmon fillets in the air fryer basket. Cook for 8-10 minutes, or until cooked through. Cooking times will vary slightly between different air fryer models.
Pro Tips & Troubleshooting
Pro Tips
- Don’t overcook the salmon; it should be slightly pink in the center for the best texture.
- Use a meat thermometer to ensure the salmon reaches the correct internal temperature.
- Marinate the salmon for at least 30 minutes to allow the flavors to fully develop.
- Make the avocado salsa right before serving to prevent it from browning.
- If you don’t have fresh lime zest, you can use bottled lime juice, but fresh is best for a more vibrant flavor.
- For a spicier salsa, leave the seeds in the jalapeno.
- Pat the salmon dry before searing to get a crispy skin.
- Use a hot pan to get a good sear on the salmon.
Common Mistakes to Avoid
- Overcooking the salmon (it becomes dry and tough).
- Using unripe avocados (they are hard and tasteless).
- Not marinating the salmon long enough (the flavors don’t develop).
- Making the salsa too far in advance (it browns and becomes mushy).
- Skipping the step of patting the salmon dry before searing.
- Not using enough butter or oil in the pan.

FAQ
How long does the avocado salsa last, and how should it be stored?

What is the best way to cook salmon for this recipe to achieve the best texture?

What side dishes pair well with this keto salmon dish?
