Sauces & Condiments
This bacalao salad dressing recipe transforms simple greens into a Mediterranean masterpiece with its bright, tangy profile that cuts through salty cod perfectly.
The secret lies in balancing lemon's acidity with fresh dill and a touch of olive oil, creating a dressing that enhances rather than overpowers the delicate flavors of bacalao. I developed this after realizing store-bought dressings lacked the depth needed to complement properly desalted cod.
The dressing comes together in minutes with just five ingredients—fresh lemon juice, extra-virgin olive oil, finely chopped dill, a pinch of salt, and a splash of bacalao-infused water for that signature umami depth.
The texture is silky yet light, clinging beautifully to mixed greens or sliced cod without weighing them down. This isn't just another vinaigrette; it's a flavor bridge that elevates every bite.
What makes this dressing truly special is its versatility—it works equally well on crisp arugula salads, hearty grain bowls, or even as a marinade for seafood. The lemon-dill combination brightens the natural richness of bacalao while the olive oil adds a luxurious finish.
Once you try it, you'll never go back to bland bottled dressings again.
Perfect for Mediterranean-inspired meals or when you want to add restaurant-quality flavor to your home cooking. The dressing keeps well in the fridge for up to five days, making it ideal for meal prep. Let's create this bright, zesty companion for your next bacalao dish.
Ingredients for bacalao salad dressing
Five ingredients that turn ordinary salads into Mediterranean brilliance with cod-infused umami.
| Ingredient | Amount | Notes |
|---|---|---|
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity variety preferred |
| Fresh Lemon Juice 🍋 | ¼ cup | Freshly squeezed, no pulp |
| Fresh Dill 🌿 | ¼ cup | Finely chopped, stems removed |
| Bacalao-Infused Water 🐟 | ⅛ cup | From soaking desalted cod |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Garlic Cloves 🧄 | 1 clove | Minced, for subtle depth |
| Honey 🍯 | 1 tsp | Lightly sweetens acidity |
The olive oil here isn't just any oil—look for extra-virgin with fruity notes at Whole Foods or Trader Joe's for that premium finish. Fresh dill is a must; dried won't cut it—the bright, grassy flavor is essential. For the bacalao-infused water, save the soaking liquid from properly desalted cod (about 1 cup water to 1 lb cod). If you're short on time, fish stock works in a pinch, but it lacks that signature depth. The garlic and honey are just subtle touches—don't overthink them, but don't skip them either.
No fresh dill? Fresh parsley at half the amount gives a milder flavor, but you'll miss that signature bacalao dressing taste. Out of honey? Maple syrup works equally well. Running low on olive oil? Avocado oil maintains the same neutral profile. The lemon juice can be bottled in a bind, but fresh is worth the squeeze—Meyer lemons add a touch of sweetness. If you're feeling adventurous, add a pinch of smoked paprika for a smoky twist that pairs beautifully with cod.
This dressing keeps beautifully—up to 5 days in an airtight jar in the fridge. The flavors actually improve overnight as everything melds. For meal prep, I double the batch and store it in two smaller jars. The olive oil will solidify slightly in the fridge, so give it a gentle shake before using. It's perfect for dressing salads, drizzling over grilled fish, or even tossing with roasted vegetables. The bacalao-infused water adds a unique umami note that makes this dressing truly special.

Step-by-step instructions for bacalao-inspired dressing
Here's how to blend this bright, salty dressing that transforms simple greens into a Mediterranean masterpiece.
Whisk Together the Base Ingredients
In a medium bowl, combine the 0.5 cup extra-virgin olive oil and 0.25 cup fresh lemon juice. I like to use a fork first to break up any oil clumps, then switch to a whisk for a smoother texture. The lemon juice will immediately start to emulsify with the oil, creating a silky base.
Add the 0.25 cup finely chopped fresh dill and 1 clove minced garlic. Stir well to distribute the herbs evenly—you want every bite of your salad to taste like a burst of garden freshness. The dill should be finely chopped so it dissolves into the dressing rather than sitting as chunks.
Add the Bacalao Infusion
Pour in the 0.125 cup bacalao-infused water from your soaked cod. This salty, umami-rich water is the secret ingredient that transforms this dressing from good to extraordinary. The saltiness balances the bright lemon and mellows the garlic's sharpness, creating that perfect Mediterranean harmony.
Add the 0.5 teaspoon sea salt and 1 teaspoon honey, then whisk vigorously for about 30 seconds until everything is fully incorporated. The honey helps round out the acidity from the lemon while adding just a touch of sweetness that complements the salty bacalao notes.
Taste and Adjust for Perfection
Give the dressing a taste and adjust the seasoning as needed. If it needs more acidity, add another splash of lemon juice. Need more salt? Add a pinch at a time—the bacalao water already contributes significant saltiness, so go slow. The dressing should taste vibrant and balanced, with the lemon shining through but not overpowering the other flavors.
Let the dressing rest for 10 minutes before using. This brief resting period allows all the flavors to meld together beautifully. The dressing will thicken slightly as the ingredients absorb each other's flavors, creating a luxurious texture that clings perfectly to greens.
Store and Use
Transfer the dressing to a clean jar with a tight-fitting lid. It will keep in the refrigerator for up to 5 days, though I find it's best used within the first 3 days when all the flavors are at their peak. The bacalao-infused water gives it a unique character that develops over time, but freshness is key for that bright lemon flavor.
Use this dressing liberally over mixed greens, grilled vegetables, or even as a marinade for proteins. The salty depth pairs beautifully with grilled fish, chicken, or even roasted vegetables. For an extra touch, sprinkle with additional fresh dill or a pinch of flaky sea salt right before serving.
Pro Tips For Making Bacalao Salad Dressing
- Strain Twice: The bacalao-infused water’s flavor is delicate—don’t risk cloudiness. Strain it through a fine-mesh sieve first, then a coffee filter or cheesecloth for a silky finish. I used to skip this, and the dressing always looked murky no matter how much I shook it.
- Salt the Dill: Toss fresh dill with a pinch of sea salt before blending—it softens the leaves and prevents that bitter aftertaste. Works especially well if your dill is young or slightly woody. (Yes, even if you’re impatient like me.)
- Whisk, Don’t Shake: Emulsify the dressing by whisking vigorously, not shaking the jar. Shaking creates air bubbles and weakens the emulsion, making it split later. A quick 30-second whisk with a fork or small whisk does the trick—no blender needed.
- Use Aged Lemon Juice: Let fresh lemon juice sit for 10 minutes before adding it to the dressing. The acidity mellows slightly, balancing the salty bacalao notes. I was skeptical until I tried it—now I always do it.

Frequently asked questions
Can I make this dressing without bacalao-infused water?
Yes! If you don't have bacalao-infused water, use ¼ cup fish stock or even ¼ cup water with ½ teaspoon extra sea salt. The umami depth will be slightly different but still delicious. For a stronger flavor, add ½ teaspoon anchovy paste or a pinch of MSG to mimic the bacalao's savory notes.
How do I store leftover dressing?
Transfer to an airtight jar and refrigerate for up to 5 days. The flavors actually improve over time! Give it a gentle shake before using—it may thicken slightly in the fridge. For longer storage, freeze in ice cube trays for up to 3 months, then thaw in the fridge before using.
What's the best way to use this dressing?
This dressing shines on mixed greens, grilled fish, or Mediterranean bowls. For extra flair, drizzle over roasted vegetables or use as a marinade for seafood or chicken. The bright lemon-dill flavor also works beautifully with couscous salads or as a dip for warm pita.
Can I make this dressing without honey?
Swap the honey for 1 teaspoon maple syrup or agave nectar for a similar sweetness. If you prefer no sweetener, simply omit it—the dressing will still taste balanced, though the lemon's acidity will be slightly sharper. For a savory twist, add ½ teaspoon Dijon mustard instead.
Why does my dressing separate?
This can happen if the oil and lemon juice aren't properly emulsified. Whisk vigorously for 30-60 seconds to combine them, then add the other ingredients. If it separates later, just whisk again before using. For a more stable dressing, add 1 teaspoon Dijon mustard or 1 yolk (for a richer version) to help bind the ingredients.
