Grilled Lemon Mustard Salmon With Sour Cream

The first time I tasted salmon prepared this way, it was at a summer barbecue hosted by my aunt, a legendary figure in our family for her effortless entertaining. The scent of the smoky grill mingled with the bright, citrusy aroma of the marinade, and the first bite was an explosion of flavors. The tender, flaky salmon, infused with lemon and mustard, paired perfectly with the cool, tangy sour cream sauce. To this day, that meal represents the joy of simple, fresh ingredients cooked with love and shared with family. I’ve tweaked it a little over the years, but it always brings me back to her sun-drenched patio.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 10-17 minutes
• Total Time: 20-27 minutes
• Servings: 4
• Dietary Type: Pescatarian

Ingredients

For the Salmon:

• 2 tablespoons olive oil
• 2 tablespoons lemon juice
• 2 teaspoons Dijon mustard
• 1 garlic clove, minced
• 1 lb salmon fillet

For the Sour Cream Dill Sauce:

• ½ cup sour cream
• 1 tablespoon fresh dill, chopped
• 1 tablespoon fresh chives, chopped
• 1 teaspoon Dijon mustard
• 1 teaspoon lemon juice

Equipment Needed

• 8-inch square baking dish (or large resealable plastic bag)
• Small bowl
• Whisk or fork
• Grill

Instructions

1. In an 8-inch square baking dish, or a large resealable plastic bag, combine the olive oil, lemon juice (2 tablespoons), Dijon mustard (2 teaspoons), and minced garlic. Blend the ingredients thoroughly.
2. Add the salmon fillet to the marinade, turning it to coat all sides. This ensures even flavor distribution throughout the fish.
3. Cover the baking dish or seal the plastic bag, and refrigerate for 1 to 2 hours. Turn the salmon once or twice during marination to further enhance flavor penetration.
4. While the salmon is marinating, prepare the Sour Cream Dill Sauce. In a small bowl, combine the sour cream, chopped fresh dill, chopped fresh chives, Dijon mustard (1 teaspoon), and lemon juice (1 teaspoon). Mix well.
5. Cover the sauce and refrigerate it to allow the flavors to meld together. The longer it sits, the better it will taste.
6. Heat your grill to medium-high heat. If using a gas grill, preheat it with the lid closed for at least 10 minutes. If using a charcoal grill, ensure the coals are glowing and covered with a light ash.
7. When the grill is ready, oil the grill rack. This prevents the salmon from sticking and ensures a clean release. A high-heat oil like grapeseed or avocado oil works best.
8. Place the salmon fillet, skin side down, on the preheated grill. If using a gas grill, cook over medium-high heat. If using a charcoal grill, position the salmon 4 to 5 inches from the medium-high coals.
9. Cook the salmon for 10 to 17 minutes, or until the fish flakes easily with a fork. Turn the salmon once during cooking, being careful not to break it apart. The cooking time will vary depending on the thickness of the fillet and the heat of your grill. A digital thermometer inserted into the thickest part of the salmon should read 145°F (63°C).
10. Once cooked, remove the salmon from the grill and cut it into 4 pieces. Serve immediately with a generous dollop of the chilled Sour Cream Dill Sauce.

Expert Tips & Tricks

• Don’t Overcook the Salmon: Salmon is best when cooked to medium. Overcooked salmon will be dry and less flavorful. Use a digital thermometer to ensure perfect doneness.
• Marinate Smart: While the recipe calls for 1-2 hours of marinating time, you can marinate the salmon for up to 4 hours for an even stronger flavor. Avoid marinating for longer than that, as the acid in the lemon juice can start to break down the texture of the fish.
• Grill Pan Alternative: If you don’t have a grill, you can use a grill pan on your stovetop. Heat the grill pan over medium-high heat and cook the salmon as directed, ensuring good ventilation in your kitchen.
• Skin-On vs. Skinless: Leaving the skin on the salmon while grilling helps to keep the fish moist and adds flavor. The skin can be easily removed after cooking, if desired.
• Add Some Heat: For a spicy kick, add a pinch of red pepper flakes to the salmon marinade or the sour cream sauce.

Serving & Storage Suggestions

This Grilled Lemon Mustard Salmon is delicious served hot, right off the grill. It pairs well with a variety of sides, such as grilled asparagus, roasted vegetables, quinoa, or a simple green salad. The bright flavors of the salmon and sauce complement these sides perfectly.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the salmon in a low oven (around 275°F or 135°C) or in a skillet over low heat. Avoid microwaving, as this can dry out the fish. The sour cream sauce is best served cold and should be stored separately. It’s not recommended to freeze the cooked salmon, as freezing can affect the texture of the fish.

Variations & Substitutions

• Herb Variations: Experiment with different fresh herbs in the sour cream sauce. Try tarragon, parsley, or even a hint of mint for a unique flavor profile.
• Citrus Swap: While lemon is classic, you could substitute lime or orange juice for a different citrusy twist.
• Mustard Options: If you don’t have Dijon mustard, whole-grain mustard or even a mild yellow mustard can be used as a substitute, though the flavor will be slightly different.
• Dairy-Free Option: Use a plant-based sour cream alternative made from cashews or coconut for a dairy-free version. Ensure the plant-based sour cream is unflavored for best results.
• Honey Glaze: For a touch of sweetness, whisk a tablespoon of honey into the marinade. This creates a lovely glaze on the salmon as it grills.

FAQs (Frequently Asked Questions)

Q: How do I know when the salmon is cooked through?
A: The salmon is done when it flakes easily with a fork and the internal temperature reaches 145°F (63°C). Use a digital thermometer inserted into the thickest part of the fillet for accuracy.

Q: Can I use frozen salmon for this recipe?
A: Yes, but make sure to thaw the salmon completely before marinating. Pat it dry with paper towels to remove excess moisture.

Q: Can I make the sour cream sauce ahead of time?
A: Absolutely! In fact, the sauce benefits from sitting in the refrigerator for at least 30 minutes to allow the flavors to meld together. You can prepare it up to a day in advance.

Q: What if I don’t have fresh dill or chives?
A: Dried dill and chives can be used as a substitute, but use about one-third the amount. Fresh herbs provide a brighter, more vibrant flavor.

Q: Can I bake the salmon instead of grilling it?
A: Yes, you can bake the salmon in a preheated oven at 400°F (200°C) for 12-15 minutes, or until it flakes easily with a fork.
