Ingredients

• 4 salmon fillets (6 ounces each, skin-on preferred)

• 4 tablespoons unsalted butter

• 3 cloves garlic, finely minced

• 1 tablespoon olive oil (for searing)

• 1 tablespoon fresh lemon juice (plus wedges for serving)

• 1 teaspoon lemon zest

• 1/2 teaspoon smoked paprika (or regular paprika)

• 1/4 teaspoon red pepper flakes (optional heat)

• 2 tablespoons fresh parsley, chopped

• Salt and black pepper, to taste

• Lemon slices (optional, for pan-roasting aroma)

Step-by-Step Instructions

• Pat the salmon dry with paper towels. Season both sides with salt, pepper, and smoked paprika. Dry fish equals better sear. Science wins.
• Heat a large oven-safe skillet over medium-high. Add 1 tablespoon olive oil. When shimmering, place salmon skin-side down. Don’t poke it—let the crust form for 3–4 minutes.
• While it sears, melt 4 tablespoons butter in a small saucepan over low heat. Add minced garlic and cook 30–45 seconds until fragrant (not browned). Stir in lemon juice, lemon zest, and red pepper flakes.
• Flip the salmon carefully. Spoon half the garlic butter over the tops. If using, tuck a few lemon slices into the pan around the fillets for aroma.
• Transfer skillet to a preheated 400°F (205°C) oven and roast 6–8 minutes, depending on thickness, until the salmon flakes easily or hits 125–130°F in the thickest part for medium. FYI, it will carryover-cook a bit.
• Remove and spoon the rest of the garlic butter over the fish. Sprinkle with fresh parsley. Let it rest 2 minutes to reabsorb juices. Serve with lemon wedges and your favorite keto sides.

How Long Does It Keep?

Cooked salmon keeps 3 days in the fridge in an airtight container. Reheat gently on low heat in a skillet with a splash of water or butter to avoid drying it out.

It’s also delicious cold over a salad because, let’s be honest, cold leftover salmon and garlic butter is dangerously good. Freezing?

Possible, but texture suffers—eat it fresh if you can.

Healthy Reasons to Try This

• Omega-3 powerhouse: Salmon is loaded with EPA and DHA to support brain and heart health.
• Keto-aligned fats: Butter and olive oil boost satiety and flavor without carbs.
• Protein-forward: Each serving delivers high-quality protein to support muscle and recovery.
• Low inflammation ingredients: Garlic, olive oil, and lemon play nicely with a real-food, low-carb approach.

Common Mistakes to Avoid

• Starting with wet fish: Moisture kills sear.
  

  Pat dry like you mean it.

• Overcooking: Salmon turns chalky past 140°F. Pull at 125–130°F for silky texture.
• Burning the garlic: Garlic goes from fragrant to bitter fast.
  

  Keep it on low heat in butter.

• Skipping the rest: Two minutes off heat lets juices redistribute. Don’t rush greatness.
• Underseasoning: Salt matters.
  

  You’re cooking salmon, not whispering to it.

Creative Twists

• Cajun Kick: Swap paprika for Cajun seasoning and add a squeeze of lime instead of lemon.
• Herb Garden: Stir chopped dill, chives, and basil into the butter for a green, summery vibe.
• Browned Butter Upgrade: Let the butter cook until golden and nutty before adding garlic—next-level flavor.
• Sheet Pan Mode: Add asparagus or broccolini to the pan and roast with the salmon. One pan, zero drama.
• Lemon-Caper Finish: Stir a tablespoon of capers into the butter for briny punch.

FAQ

Can I use frozen salmon?

Yes.

Thaw it overnight in the fridge or under cold running water in sealed packaging. Pat extremely dry before searing.

Frozen fish can release more moisture, so a little extra time in the pan helps build that crust.

Skin-on or skinless?

Skin-on is best. It protects the flesh during sear and bakes up crispy.

If you’re not into eating the skin, cook with it on, then slide it off after—it still did its job.

What pan works best?

A heavy stainless-steel or cast-iron skillet handles high heat and creates a better crust. Nonstick is fine in a pinch, but don’t crank it to oblivion.

Oven-safe is ideal so you can finish in the oven without pan juggling.

How do I know it’s done without a thermometer?

Gently press the top—if it flakes easily and the center is translucent-to-opaque, you’re there. Another hint: the albumin (that white protein) should be minimal; if it’s gushing out, you’ve gone too far, unfortunately.

Is this dairy-free if I switch to ghee?

Ghee removes milk solids and is often tolerated by people who avoid dairy, but it’s still derived from butter.

If you need fully dairy-free, use olive oil and finish with a squeeze of lemon and fresh herbs. Flavor will be lighter but still excellent.

What sides are keto-friendly?

Try roasted asparagus, garlic green beans, sautéed zucchini, cauliflower mash, or a crisp arugula salad with olive oil and Parmesan.

Keep it simple and let the salmon flex.
