Ingredients

• 4 salmon fillets (about 6 ounces each), skin-on or skinless
• 2 tablespoons olive oil (or avocado oil)
• 2 tablespoons unsalted butter or ghee
• 2 cloves garlic, finely minced
• Zest of 1 lemon
• Juice of 1 lemon (about 2 tablespoons)
• 1 tablespoon fresh parsley, chopped
• 1 tablespoon fresh dill, chopped (or 1 teaspoon dried)
• 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
• 1/2 teaspoon sea salt, plus more to taste
• 1/4 teaspoon black pepper
• Optional: 1/4 teaspoon red pepper flakes for gentle heat
• Lemon slices, for garnish

Step-by-Step Instructions

1. Prep the oven and pan: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment or lightly oil a cast-iron skillet if you plan to bake or finish in the oven.
2. Pat the salmon dry: Use paper towels to remove excess moisture.

   This helps the salmon sear better and prevents steaming.

3. Make the lemon herb mixture: In a small bowl, combine olive oil, melted butter or ghee, garlic, lemon zest, lemon juice, parsley, dill, thyme, salt, pepper, and red pepper flakes if using.
4. Season the fillets: Place salmon on the prepared sheet or in the skillet. Spoon or brush the lemon herb mixture evenly over the tops. Tuck a lemon slice on each fillet if you like.
5. Bake: Cook for 10–12 minutes, depending on thickness.

   The salmon should flake easily with a fork and reach an internal temperature of about 125–130°F for medium (or up to 145°F if you prefer well-done).

6. Optional broil: For a lightly caramelized top, broil for 1–2 minutes at the end. Watch closely to prevent overcooking.
7. Rest and serve: Let the salmon rest for 2–3 minutes. Spoon any pan juices over the top.

   Garnish with extra herbs and a squeeze of lemon.

Storage Instructions

• Refrigerator: Store leftovers in an airtight container for up to 3 days.
• Freezer: Cooked salmon can be frozen for 2–3 months. Wrap tightly and store in a freezer-safe bag or container.
• Reheating: Warm gently at 275–300°F (135–150°C) for 10–12 minutes, or microwave in short bursts at 50% power to avoid drying out. Add a small pat of butter or a squeeze of lemon to refresh.
• Cold serving: Flaked cold salmon is excellent over greens with olive oil, lemon, and capers.

Benefits of This Recipe

• Keto-aligned macros: High in healthy fats and protein, virtually no carbs.
• Omega-3 rich: Salmon supports heart, brain, and joint health.
• Clean ingredients: No added sugars or processed thickeners—just herbs, citrus, and whole foods.
• Meal prep friendly: Cooks fast and holds up well for lunches and quick dinners.
• Versatile pairing: Works with simple sides like roasted asparagus, sautéed zucchini, or a crisp salad.

Pitfalls to Watch Out For

• Overcooking: Salmon turns dry quickly.

  Start checking at 8–9 minutes if your fillets are thin.

• Too much lemon juice up front: Excess acidity can “cook” the fish and make it mushy. Stick to the amounts, then add more at the end if needed.
• Wet surface: Not patting the fish dry can prevent browning and create a watery bake.
• Old herbs: Tired or brown herbs will dull the flavor. Use fresh or good-quality dried.
• Uneven thickness: If some fillets are thinner, pull them out earlier or fold thinner ends under for even cooking.

Variations You Can Try

• Air fryer: Cook at 390°F (200°C) for 7–10 minutes, depending on thickness.
• Pan-seared then oven-finished: Sear skin-side down in a hot skillet with oil for 3–4 minutes, flip, add lemon herb mixture, and finish in a 400°F oven for 5–7 minutes.
• Herb switch: Swap dill for basil, parsley for cilantro, or add chives for a gentle onion note.
• Garlic butter caper sauce: Stir 1 tablespoon capers into the butter for briny brightness.
• Spice it up: Add a pinch of smoked paprika or Aleppo pepper for warmth.
• Dairy-free: Replace butter with more olive oil or dairy-free ghee.
• Sheet pan supper: Add asparagus or broccolini tossed with olive oil and salt to the pan; roast alongside the salmon.

FAQ

Can I use frozen salmon?

Yes.

Thaw it in the fridge overnight or in a sealed bag under cold running water. Pat dry very well before seasoning to avoid a watery bake.

Skin-on or skinless—what’s better?

Skin-on helps keep the fillet moist and releases easily from a hot surface. You can remove the skin after cooking if you prefer.

How do I know when salmon is done?

Look for opaque flesh that flakes easily with a fork.

For best texture, aim for an internal temperature around 125–130°F for medium. It will rise a bit as it rests.

Is this recipe gluten-free?

Yes, it’s naturally gluten-free. Just check that your butter, ghee, or seasonings contain no additives with gluten.

What sides go well with this?

Try roasted asparagus, sautéed spinach with garlic, zucchini ribbons, cauliflower mash, or a simple arugula salad with olive oil and lemon.

Can I make this on the grill?

Absolutely.

Oil the grates well, cook skin-side down over medium heat for 6–8 minutes, then finish for 2–4 minutes on the other side. Brush with the lemon herb mixture as it cooks.
