Ingredients You’ll Need

With just a handful of everyday ingredients, you can create a Dill Mustard Sauce that absolutely bursts with flavor. Each element plays its own delicious role, so don’t skip a thing!

Dijon Mustard: The creamy backbone of the sauce, lending tangy depth and a little sharpness.
Honey (or maple/agave syrup): Balances the pungency of the mustard with a hint of natural sweetness; use maple or agave for a vegan twist.
Cider Vinegar: Adds bright acidity and balances out the richness of the olive oil.
Lemon Juice: Freshly squeezed is best for clean, citrusy zing that really makes the flavors pop.
Extra-Virgin Olive Oil: Gives the sauce a silky, luscious texture while mellowing its sharpest notes.
Fresh Dill: The star herb—dill delivers that signature fresh, aromatic bite.
Fresh Parsley: Adds a green, grassy brightness and balances the bolder dill flavor.

Variations

This sauce is wonderfully customizable, so go ahead and put your own spin on it! Whether you’re accommodating dietary needs or just craving a new twist, these variations are foolproof.

Add Yogurt or Sour Cream: For a creamier, more luscious version, swirl in a tablespoon of Greek yogurt or sour cream.
Spice It Up: Stir in a pinch of crushed red pepper or a dab of horseradish for an extra kick.
Go All-Herb: Try adding chopped chives or tarragon to amp up the herbaceous notes even further.
Make It Vegan: Use your favorite plant-based syrup (like maple or agave) instead of honey to keep this sauce fully vegan.

How to Make Dill Mustard Sauce

Step 1: Gather and Prep Your Ingredients

Before you start, chop your fresh dill and parsley and have everything measured and ready to go. This means you can whip up your Dill Mustard Sauce in one smooth, stress-free swoop—perfect for a speedy weeknight dinner or last-minute brunch!

Step 2: Combine and Whisk

Add the Dijon mustard, honey (or your chosen sweetener), cider vinegar, lemon juice, and olive oil to a mixing bowl. Toss in your freshly chopped dill and parsley. Now whisk everything together energetically until the mixture is creamy, emulsified, and flecked with those gorgeous green herbs.

Step 3: Taste and Adjust

This is your moment to make the Dill Mustard Sauce truly your own! Give it a taste. If you like it tangier, add a touch more lemon juice or vinegar. For extra sweetness or if your mustard is quite sharp, an extra dab of honey works wonders. Season with a pinch of salt and black pepper if desired.

Pro Tips for Making Dill Mustard Sauce

Herb Freshness Matters: Always use fresh dill and parsley—dried herbs won’t deliver that same punchy flavor or lovely color.
Whisk for Creaminess: Vigorously whisking helps emulsify the olive oil, creating a lusciously smooth and glossy sauce.
Flexible Sweetness: Dijon brands can vary in strength, so start with less honey (or syrup), then adjust to taste after whisking.
Let It Mingle: For maximum flavor, let your Dill Mustard Sauce rest in the fridge for 30 minutes so the herbs infuse the sauce.

How to Serve Dill Mustard Sauce

Garnishes

Give your Dill Mustard Sauce a final flourish with a sprinkle of extra fresh dill, a little zest of lemon, or a dusting of cracked black pepper. These simple touches don’t just make it look restaurant-worthy—they add even more freshness to every bite.

Side Dishes

This sauce turns even the simplest side into something special! Spoon it over new potatoes or grilled asparagus, swirl it into a bowl of quinoa, or serve as a dip with crisp, raw veggies for a light but flavor-packed lunch.

Creative Ways to Present

For a show-stopping appetizer, try drizzling your Dill Mustard Sauce on a platter of smoked salmon, or offer it in small jars as a dipping sauce for an elegant crudité board. For picnics, pack it in a mason jar to bring bright flavor to wraps, salads, or grain bowls on the go.

Make Ahead and Storage

Storing Leftovers

Simply transfer any leftover Dill Mustard Sauce to an airtight container and pop it in the refrigerator. It keeps beautifully for up to a week—just give it a quick stir before serving, as natural separation may occur.

Freezing

While this sauce is best fresh, you can freeze it if needed. Pour into a small container or ice cube tray, cover tightly, and freeze for up to one month. Thaw in the fridge, then whisk well, as the herbs and oil may separate a bit.

Reheating

Dill Mustard Sauce is designed to be served chilled or at room temperature, so there’s no need to reheat it! If it’s come straight from the fridge, just stir well and let it sit out for a few minutes to take the chill off before using.

FAQs

Can I make Dill Mustard Sauce ahead of time?

Absolutely! In fact, making it ahead gives the flavors time to meld and deepen. Just store it in a covered jar in the fridge and stir before serving.
What can I use instead of fresh dill?

If fresh dill isn’t on hand, use half the amount of dried dill, though the flavor will be milder. You can also swap in chives or tarragon for a different herbal note.
Is this sauce vegan and gluten-free?

When you use maple or agave syrup instead of honey, Dill Mustard Sauce is entirely plant-based and naturally gluten-free, making it perfect for sharing with a crowd.
How can I thicken my Dill Mustard Sauce?

If you want a thicker, creamier consistency, whisk in a spoonful of Greek yogurt or sour cream, or use a bit less olive oil to concentrate the flavors.
