Ingredients

For the Rosemary Salmon

• 4 salmon fillets (about 6 ounces each), skin on
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 2 sprigs fresh rosemary
• 2 cloves garlic, minced
• 1 lemon (zest and juice)
• Salt and black pepper to taste

For the Mashed Potatoes

• 2 pounds Yukon Gold potatoes, peeled and cut into chunks
• 4 tablespoons unsalted butter
• ½ cup whole milk (or heavy cream if you like them extra creamy)
• Salt and pepper to taste
• 2 tablespoons sour cream (optional, for tang)

For the Fresh Garden Salad

• 4 cups mixed greens (romaine, spinach, or arugula)
• 1 cucumber, thinly sliced
• 1 cup cherry tomatoes, halved
• ½ red onion, thinly sliced
• 2 tablespoons extra virgin olive oil
• 1 tablespoon balsamic vinegar or lemon juice
• Salt and pepper to taste

Step-by-Step Instructions

1. Make the Mashed Potatoes

1. Place the potatoes in a large pot of cold salted water. Bring to a boil and cook for about 15 to 20 minutes, or until they’re tender when pierced with a fork.
   Pro tip: Starting with cold water helps the potatoes cook evenly.
2. Drain the potatoes well, then return them to the pot. Add the butter, warm milk, salt, and pepper. Mash until smooth and creamy. Stir in sour cream if using.
   Pro tip: Warm milk helps the potatoes stay silky instead of clumpy.

2. Cook the Rosemary Salmon

1. Pat the salmon fillets dry with paper towels. Season both sides with salt, pepper, and lemon zest.
   Pro tip: A dry surface gives you that crisp, golden sear.
2. Heat the olive oil in a skillet over medium-high heat. Place the salmon skin-side down and let it cook for 4 to 5 minutes without moving it. This will give you perfectly crispy skin.
3. Flip the salmon, lower the heat, and add the butter, rosemary sprigs, and minced garlic. Spoon the melted butter over the salmon as it cooks for another 3 to 4 minutes.
4. Squeeze lemon juice over the salmon before taking it off the heat.
   Pro tip: Don’t overcook. The salmon should flake easily with a fork and stay juicy inside.

If you prefer baking, you can also cook the salmon in the oven at 400°F for 12 to 15 minutes.

3. Assemble the Salad

1. In a large bowl, combine the greens, cucumber, tomatoes, and onion.
2. Drizzle with olive oil and balsamic vinegar (or lemon juice). Season with salt and pepper, then toss gently to coat.
   Pro tip: Dress the salad right before serving to keep it crisp.

4. Plate and Serve

Scoop a generous portion of mashed potatoes onto the plate. Add the salmon fillet next to it, then pile on some fresh salad. Garnish with rosemary or a lemon wedge if you like.

Tips for Success

1. Fresh salmon always tastes better than frozen.
2. Let the salmon sear undisturbed at first for the best skin.
3. Warm your milk before adding it to the potatoes for a smoother texture.
4. A splash of lemon or vinegar brightens the richness of the dish.
5. Serve the salmon right away so it stays moist and tender.
6. Dress the salad at the last minute so it doesn’t wilt.
7. Garnish thoughtfully for a restaurant-worthy presentation.

Variations & Substitutions

• Grilled salmon: Brush with rosemary butter and cook on the grill.
• Different herbs: Try thyme or dill if you don’t have rosemary.
• Low carb: Swap mashed potatoes for mashed cauliflower.
• Add heat: A pinch of red pepper flakes gives it a gentle kick.
• Dairy-free: Use olive oil instead of butter and plant-based milk.

What to Serve With Rosemary Salmon

• A slice of warm garlic bread to soak up the lemon butter.
• A glass of chilled Sauvignon Blanc or Chardonnay.
• Roasted asparagus or broccoli for extra greens.
• A light dessert like lemon sorbet or panna cotta.

Storage & Reheating

• Fridge: Store leftovers in airtight containers for up to 3 days. Keep salmon, potatoes, and salad separate.
• Freezer: The salmon and mashed potatoes can be frozen for up to a month. Wrap the salmon well to avoid freezer burn.
• Reheating: Warm salmon gently in a skillet or oven at 300°F for about 10 minutes. Add a splash of milk to the potatoes when reheating to keep them creamy.

Pro tip: Avoid over-microwaving salmon. It dries out fast.

Common Mistakes to Avoid

1. Overcooking the salmon. Take it off the heat when the center is just opaque.
2. Using cold milk and butter in mashed potatoes. This makes them heavy and lumpy.
3. Forgetting to pat the salmon dry before searing. Moisture keeps the skin from crisping up.
4. Dressing the salad too early, which makes it soggy.
5. Crowding the skillet and steaming the salmon instead of searing it.

FAQs

Can I use frozen salmon fillets?
Yes, just thaw them completely and pat them dry before cooking.

What potatoes are best for mashing?
Yukon Golds are great for creamy mash. Russets work well too if you prefer a fluffier texture.

How can I tell when the salmon is done?
It should flake easily with a fork and have an internal temperature of about 125–130°F.

Can I make this ahead of time?
Yes. You can prepare the mashed potatoes earlier in the day and keep them warm. Cook the salmon just before serving.

How can I make the mashed potatoes extra creamy?
Use warm heavy cream and extra butter. A potato ricer gives a really smooth finish.

Can I grill the salmon instead of pan-searing?
Absolutely. Brush it with rosemary butter and grill for 3 to 4 minutes per side.

How do I keep the salad fresh if prepping ahead?
Store the vegetables and dressing separately. Toss right before serving.
