Ingredients You’ll Need
Simple, fresh ingredients are the heart and soul of this Creamy Dill Sauce with Salmon or Trout Recipe. Each one plays an important role in balancing the creamy texture, zesty brightness, and herbal freshness that make the sauce unforgettable.
- Sour Cream: Provides a smooth, tangy base that makes the sauce luxuriously creamy.
- Dijon or Hot English Mustard: Adds a subtle kick and depth of flavor that complements the fish perfectly.
- Garlic Powder or Fresh Garlic: Brings a mild savory note that enhances the overall taste without overwhelming it.
- Fresh Dill: The star herb—its slightly grassy and lemony flavor pairs beautifully with salmon and trout.
- Lemon Zest and Juice: Introduce bright citrus notes that lighten and lift the sauce’s creamy richness.
- Milk or Olive Oil: Used to adjust the sauce’s consistency, making it just right for drizzling or dipping.
- Salt: Essential to enhance all the fresh flavors and bring balance.
- White Sugar: Just a touch to gently counterbalance the tartness of the lemon and sour cream.
- Oil for Cooking: To sear the fish beautifully, creating a crisp exterior while keeping the inside tender.
- Salmon or Trout Fillets: Fresh, skin-on fillets are perfect for frying and pairing with this summery sauce.
How to Make Creamy Dill Sauce with Salmon or Trout Recipe
Step 1: Prepare the Dill Sauce
Start by mixing together the sour cream, Dijon mustard, garlic (powder or minced), fresh dill, lemon zest, lemon juice, milk (or olive oil), salt, and sugar. Stir well to loosen the sour cream so the sauce becomes creamy but still thick enough to hold its shape. If you can, let the sauce rest for about 10 minutes; if using fresh garlic, 20 minutes helps the flavors meld perfectly.
Step 2: Season the Fish
Pat your salmon or trout fillets dry with a paper towel to ensure a nice sear, then sprinkle both sides generously with salt and pepper. This simple seasoning step is essential to build a balanced flavor foundation for your dish.
Step 3: Cook the Fish
Heat your favorite cooking oil in a skillet over medium-high heat until shimmering. Place the fillets skin side down carefully in the pan. You’ll want to cook for about 2 minutes on this side to get a crisp skin. Then flip and cook for another 1 1/2 minutes until the fish is just cooked through and flakes easily with a fork.
Step 4: Plate and Serve
Remove the fillets from the skillet and arrange them on serving plates. Spoon your creamy dill sauce on the side or over the top, and garnish with extra fresh dill and lemon wedges if you like. The combination of the hot, crispy fish with the cool, tangy sauce is nothing short of delicious!
How to Serve Creamy Dill Sauce with Salmon or Trout Recipe

Garnishes
Adding fresh dill sprigs and bright lemon wedges around your plated fish brings a lovely pop of color and boosts the fresh, citrusy aroma that invites you to dig right in.
Side Dishes
This sauce pairs beautifully with light, simple sides like roasted baby potatoes, steamed asparagus, or a crisp green salad. The creamy dill sauce acts as a luscious complement, uplifting any accompanying dishes without stealing the spotlight.
Creative Ways to Present
For a fun twist, try serving the fish and sauce over a bed of fluffy quinoa or herbed couscous. You can also serve the sauce as a dip alongside grilled vegetable skewers, turning it into a versatile companion at any dinner party or casual meal.
Make Ahead and Storage
Storing Leftovers
You can store any leftover creamy dill sauce in an airtight container in the refrigerator for up to 3 days. The flavors continue to deepen, making it even more delightful the next day!
Freezing
Because of the sour cream and lemon juice, freezing this sauce isn’t ideal as it could separate and lose its appealing texture once thawed. It’s best enjoyed fresh or refrigerated if storing.
Reheating
The sauce is best served cold or at room temperature. For the fish, gently reheat in a low oven or skillet for a few minutes to preserve its tender quality, then add sauce right before serving.
FAQs
Can I use dried dill instead of fresh?
Fresh dill is definitely preferred for its vibrant flavor and freshness, but if you must, substitute about one-third of the amount with dried dill. Just keep in mind the sauce will be less bright and aromatic.
Is there a way to make this sauce dairy-free?
Yes! Substitute the sour cream with a plant-based yogurt or cream, such as coconut or cashew cream, and use olive oil instead of milk to keep it creamy and tasty.
Can I prepare the sauce in advance?
Absolutely. Making the sauce at least 10 minutes ahead allows the flavors to develop. For best results, chill it in the refrigerator before serving.
What kind of mustard works best?
Dijon mustard gives a smooth, slightly tangy depth, but if you like a bit more heat and texture, hot English mustard is a fantastic alternative.
How do I know when the fish is perfectly cooked?
The fillets should have a crisp skin and be opaque all the way through. They will flake easily when tested with a fork but should still be moist inside.

Ingredients
Dill Sauce
- 3/4 cup sour cream
- 2 tsp Dijon or hot English mustard
- 1/2 tsp garlic powder or 1 small garlic clove, minced
- 2 1/2 tbsp fresh dill, finely chopped
- 1 tsp lemon zest
- 1 – 2 tbsp lemon juice
- 2 tbsp milk or olive oil (for richness)
- 1/4 – 1/2 tsp salt
- 1/2 tsp white sugar
Fish
- 4 salmon or trout fillets (125g / 4oz each)
- 1/2 – 1 tbsp oil (such as olive or vegetable oil)
- Salt and pepper to taste
Instructions
- Prepare the Dill Sauce: In a bowl, mix together sour cream, Dijon mustard, garlic (powder or fresh minced), fresh dill, lemon zest, lemon juice, milk or olive oil, salt, and sugar. Stir well to loosen the sour cream and combine all flavors. Adjust the thickness by adding more milk if needed and balance the tartness by adding more lemon juice to taste. Let the sauce sit for at least 10 minutes to let the flavors meld; if using fresh garlic, resting for 20 minutes is ideal.
- Season the Fish: Pat the salmon or trout fillets dry using a paper towel to remove excess moisture. Season both sides generously with salt and pepper. This will enhance the natural flavors and help achieve a good sear.
- Cook the Fish: Heat the oil in a skillet over medium-high heat until shimmering. Place the fillets skin-side down in the hot skillet. Cook undisturbed for 2 minutes to get a crispy skin and a good sear. Flip the fillets carefully and cook the other side for an additional 1 1/2 minutes until the fish is just cooked through and flakes easily.
- Serve: Transfer the cooked fish fillets onto serving plates. Serve the creamy dill sauce on the side for dipping or drizzling. Garnish with extra fresh dill sprigs and lemon wedges if desired for extra aroma and zest.
Notes
- Resting the sauce allows the garlic and herbs to infuse, enhancing the flavor.
- Use fresh dill if possible for the best herbal aroma.
- The cooking time may vary slightly depending on the thickness of the fish fillets.
- To keep the sauce dairy-free, substitute sour cream with coconut yogurt and milk with a plant-based alternative.
- Adjust lemon juice and zest to your preferred level of tartness.
- If skin-on fillets are unavailable, skip the skin-side down step but reduce cooking time to avoid overcooking.
