Salmon Fillets with Vibrant Green Sauce

• Serving platter

Instructions

1. Prepare the Salmon Marinade: In a mixing bowl, whisk together the dry white wine, olive oil, lemon juice, salt, pepper, thyme, marjoram, and 2 tablespoons of chopped fresh parsley. Ensure all ingredients are well combined.
2. Marinate the Salmon: Place the salmon fillet in a shallow dish or zip-top bag. Pour the marinade over the salmon, ensuring it is fully coated. Marinate in the refrigerator for at least three hours, turning the salmon occasionally to ensure even marination. This step infuses the salmon with flavor and helps to keep it moist during cooking.
3. Preheat the Oven: While the salmon is marinating, preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
4. Prepare the Green Sauce: This vibrant sauce is best made while the salmon is marinating. In a food processor, combine the spinach leaves, remaining parsley sprigs, watercress leaves, and green onions. Pulse until finely chopped. You may need to scrape down the sides of the bowl a few times to ensure even processing.
5. Add Flavor Boosters: Add the lemon juice, dry mustard, dry basil, and Tabasco sauce to the food processor. Blend again until the mixture is smooth and well combined.
6. Emulsify the Sauce: Add the mayonnaise to the food processor and blend until the sauce is creamy and uniform in color.
7. Fold in the Capers: Transfer the green sauce to a bowl and gently fold in the rinsed and drained capers. Be careful not to overmix, as this can cause the sauce to become thin.
8. Adjust Seasoning: Taste the green sauce and adjust the seasoning as needed. You may want to add a pinch more salt or a squeeze of lemon juice to brighten the flavors.
9. Chill the Sauce: Cover the bowl with plastic wrap and refrigerate the green sauce until ready to serve. Chilling allows the flavors to meld and the sauce to thicken slightly.
10. Bake the Salmon: Remove the salmon from the marinade and place it on a baking sheet lined with parchment paper or foil. Discard the marinade.
11. Cook the Salmon: Bake the salmon in the preheated oven for 15-20 minutes, or until it is cooked through and flakes easily with a fork. The cooking time will vary depending on the thickness of the salmon fillet.
12. Check for Doneness: To check for doneness, insert a fork into the thickest part of the salmon and gently twist. If the salmon flakes easily, it is done. Alternatively, you can use a meat thermometer; the internal temperature should reach 145 degrees Fahrenheit (63 degrees Celsius).
13. Serve: Remove the salmon from the oven and let it rest for a few minutes before serving. Spoon a generous amount of the chilled green sauce over the baked salmon fillets. Serve immediately and enjoy!

Expert Tips & Tricks

• Don’t Skip the Anchovy Paste: The anchovy paste adds a subtle umami flavor to the green sauce that complements the salmon beautifully. Don’t be afraid to use it, even if you’re not a fan of anchovies!
• Fresh Herbs are Key: The flavor of the green sauce relies heavily on fresh herbs. Use the freshest ingredients you can find for the best results. If you can’t find watercress, arugula makes a good substitute.
• Marinating Time: The salmon benefits from a long marinating time. If you’re short on time, marinate for at least one hour, but longer is better for maximum flavor.
• Prevent Overcooking: Overcooked salmon is dry and unappetizing. Keep a close eye on the salmon while it’s baking and remove it from the oven as soon as it’s cooked through.
• Skin-On or Skin-Off: Cooking salmon with the skin on helps to keep it moist and adds flavor. If you prefer, you can remove the skin after cooking.

Serving & Storage Suggestions

This Salmon Fillets with Green Sauce is delicious served with steamed broccoli, small wedges of baked squash, a tossed salad, and crusty French bread to soak up the flavorful green sauce.

Leftover salmon and green sauce should be stored separately in airtight containers in the refrigerator. The salmon will keep for up to 3 days, and the green sauce will keep for up to 4 days.

To reheat the salmon, gently warm it in the oven or microwave. Be careful not to overcook it, as it can become dry. The green sauce is best served cold, but can be warmed slightly if desired.

FAQs (Frequently Asked Questions)

Q: Can I use dried parsley instead of fresh parsley?
A: While fresh parsley is highly recommended for its vibrant flavor, you can substitute with dried parsley. Use about 1 tablespoon of dried parsley for every 2 tablespoons of fresh.

Q: Can I make the green sauce ahead of time?
A: Absolutely! The green sauce can be made up to 2-3 days in advance and stored in the refrigerator. The flavors will actually meld together even more over time.

Q: I don’t have a food processor. Can I still make the green sauce?
A: Yes, you can. Finely chop all the herbs and green onions by hand and then whisk together with the remaining ingredients. The texture won’t be as smooth, but the flavor will still be delicious.

Q: Can I grill the salmon instead of baking it?
A: Yes, grilling is a great alternative. Preheat your grill to medium-high heat and grill the salmon for about 4-6 minutes per side, or until cooked through.

Q: Can I freeze the leftover green sauce?
A: Freezing the green sauce is not recommended, as the mayonnaise may separate and become watery upon thawing. It’s best enjoyed fresh.
