Ingredients for Pan-Seared Salmon with Mashed Sweet Potatoes

• Salmon fillets (about 6 oz each) — Pat dry, then season. They provide the main protein and a rich, buttery flavor when seared.
• Mashed sweet potatoes — The creamy base that balances the rich fish with natural sweetness and color.
• Olive oil — For the sear, helping achieve that crisp finish on the salmon.
• Lemon — Zest and a touch of juice brighten the dish and cut through the richness.
• Salt and black pepper — Build flavor and balance.
• Fresh herbs (dill or parsley) — Add a fresh, aromatic finish that pairs well with fish.
• Butter — Mixed into the mashed potatoes for extra creaminess and savory depth.

Step-by-Step Guide to Making Pan-Seared Salmon with Mashed Sweet Potatoes

1. Pat the salmon dry and season with salt, pepper, and a light lemon-squeeze if desired. Let it rest briefly while you prep the pan.
2. Heat a large skillet over medium-high heat. Add olive oil and swirl to coat the bottom.
3. Place the salmon fillets in the skillet, skin-side down if applicable. Sear for 3–4 minutes, until the edges look opaque and the skin is crisp.
4. Flip the fillets and cook for another 2–4 minutes, depending on thickness, until the salmon is cooked to your liking. Remove from the heat and drizzle with a little lemon juice if you’d like extra brightness.
5. Meanwhile, warm the mashed sweet potatoes until just heated through. Stir in the butter and a pinch of salt; add lemon zest if you enjoy a fresh tang.
6. To serve, spoon a generous bed of mashed sweet potatoes onto each plate, top with a salmon fillet, sprinkle with fresh herbs, and finish with a final pinch of pepper.

Frequently Asked Questions

Can I make this with skinless salmon?

Yes. Skinless salmon cooks a bit faster and still develops a nice crust if you sear it well. You might reduce the cooking time by 1–2 minutes per side to avoid overcooking.

What if I don’t have mashed sweet potatoes?

You can substitute with mashed potatoes or even a simple cauliflower mash for a lower-carb option. The lemon and herbs still brighten the dish.

How can I tell when the salmon is done?

Look for the flesh to be opaque and separate easily with a gentle flake. If you’re using a thermometer, 125–130°F (52–54°C) for medium-rare to medium is a good target; 145°F (63°C) is safe and fully cooked.
