Tangy and creamy mustard dill sauce pairs easy and elegantly with baked salmon, but it can also be used as a condiment, salad dressing, or vegetable dip. It's a quick, easy, and healthy sauce that's ready in just 20 minutes.

I love the versatility of salmon - there are a million different ways to prepare it (like my miso butter salmon, spinach stuffed salmon, and gochujang salmon), and one of my favorite flavor pairings is with spicy mustard and fresh dill - the perfect foil for rich salmon.
Like my basil aioli and Sriracha aioli, mustard dill sauce is versatile, easy, healthy, and so delicious.
This is a very low effort recipe, but you can easily fool your guests with the beautiful presentation.

⭐️ Why This Recipe is the Best
- Dill mustard sauce is tangy, creamy, herby, with a slight mustardy kick
- Healthy and nutritious; excellent addition to a Mediterranean diet
- Quick & easy sauce for salmon that's ready in 20 minutes
- Uses simple whole foods
- Freezer-friendly recipe
🐟 Ingredient Notes
- Greek yogurt - Use a thick and tangy Greek yogurt for optimal flavor and creaminess.
- Fresh dill - I always recommend using fresh herbs whenever possible.
- Salmon - Depending on where you shop, salmon can be pricey. Wild-caught salmon is always the best, but I've purchased farmed salmon many times and it always tastes great.
- Garlic - I highly recommend using fresh garlic for optimal flavor.
📝 Sauce Variations & Substitutions
- Dill. Substitute 2 teaspoons of dried dill for fresh dill.
- Yogurt. Use your favorite brand of yogurt, although it won't be as thick as Greek yogurt.
- Mustard. I love a grainy and textured mustard, but you can use whichever type of mustard you prefer. If you're a mustard-lover, don't miss this apple gorgonzola salad featuring a mustard vinaigrette.
🔪 How To Make Mustard Dill Sauce with Baked Salmon
*See recipe card below for printable instructions.
Make dill mustard sauce: Whisk yogurt, dill, mustard, scallions, salt, and pepper in small bowl to blend. Let stand at room temperature for 30 minutes.
Preheat oven to 425°F. Place parchment paper on baking sheet.
Place salmon, skin side down, on prepared sheet. Sprinkle with garlic, salt and pepper. Bake salmon until just opaque in center, about 10-12 minutes. Drizzle ⅓ cup of sauce on salmon and serve remaining sauce on the side. Garnish with additional scallions and fresh dill.
🍽 How to Serve Dill Mustard Sauce

- Drizzle it over Japanese sweet potato fries or mashed potatoes
- Use it as a creamy salad dressing
👩🏼🍳 Expert Tips
- Storage: Place leftovers in an airtight container and store in the refrigerator for up to 4 days.
- How to freeze: Transfer completely cooled salmon to a freezer-safe container and freeze for up to 3 months. Freeze your sauce separately. To thaw, place in fridge overnight.
- How to reheat salmon: Gently reheat in the microwave, using the 30% power setting (3 or 4 will work) for 30 seconds on each side. Using the highest microwave setting may dry out your leftover salmon. Or read my post on how to reheat salmon!
- Use fresh dill. Since both mustard and dill are star players here, it's important to use fresh dill if possible.
- Don't overbake. Salmon thickness varies, but aim for 4 to 6 minutes per half-inch of thickness. You could also use an instant-read thermometer to check for doneness. The USDA recommends a minimum internal temperature of 145 degrees F. at the thickest part of the fillet.
- You can eat the salmon skin. It's actually very nutritious, so if you want to eat it, go for it! Baking salmon with the skin on also prevents the fillets from drying out while baking.
💬 Frequently Asked Questions
Use it on your favorite dishes! Any leftover sauce can be refrigerated for up to 4 days. Add it to portobello burgers, baked chicken, mashed potatoes, or meatballs for a tangy and zesty bite. Alternatively, you can use it as a condiment for sandwiches or as a sauce for sliced vegetables.
