Sauces & Condiments
This Assaggio House Salad Dressing Recipe delivers the perfect balance of umami depth and bright acidity that transforms ordinary salads into restaurant-worthy dishes. 🌟 The secret lies in the anchovy-inspired base—just a hint of those salty, savory notes—paired with aged parmesan for a rich, nutty finish that elevates every bite.

Ingredients for assaggio house salad dressing
Nine ingredients, one restaurant-worthy dressing that bridges bold and delicate flavors perfectly.
| Ingredient | Amount | Notes |
|---|---|---|
| Anchovy Fillets 🐟 | 2 tbsp | High-quality, finely chopped |
| Extra-Virgin Olive Oil 🫒 | ¾ cup | Fruity, high-quality preferred |
| White Wine Vinegar 🍷 | ¼ cup | Dry, crisp variety |

The anchovies are non-negotiable here—they're what gives this dressing that signature Italian trattoria umami. Look for high-quality fillets at specialty stores or the Italian market section of larger grocery chains. I always grab mine from Whole Foods or Eataly if I'm feeling fancy, but the regular supermarket stuff works fine if it's fresh. Freshly grated Parmesan is a must too—pre-grated tastes like sawdust in comparison. For the olive oil, California Olive Ranch or Colavita are my go-tos, but any fruity, high-quality EVOO will do. The tarragon and basil? Grab fresh from the store and chop them right before adding to the dressing—nothing beats the aroma of fresh herbs.
No anchovies? Fish sauce at half the amount gets you close, though it won't have that same salty depth. Running out of tarragon? Fresh thyme at the same quantity works in a pinch. The Dijon mustard is key for emulsification—don't skip it. If you're using pre-grated Parmesan, strain it through a fine-mesh sieve to remove the clumps. The honey balances the anchovy's intensity, so if you're avoiding it, agave nectar at the same amount is a good swap. For storage, I always keep mine in a clean, airtight jar—it stays fresh for 10 days in the fridge, and the flavors actually develop more over time.
This dressing is a meal prep dream—make a double batch and store it in the fridge for up to 10 days. The emulsification gets better with time, so it tastes even more luxurious after a day or two. I like to keep it in a small glass jar with a tight seal—shake it before each use to redistribute the oil. It's perfect for salads, roasted veggies, or even drizzled over grains. The Parmesan crystals add a satisfying crunch with every pour, making it feel like a special occasion dressing. Trust me, you'll want to make this all the time once you try it.

Step-by-step instructions for anchovy-inspired umami dressing
Here's how to craft a velvety, perfectly balanced dressing that elevates any salad.
👨🍳 Step 1: Soften the Anchovies and Mustard
Place the 2 tbsp anchovy fillets in a small bowl and cover with 1 tbsp Dijon mustard. Let them sit for 5 minutes while you prepare the rest. This step transforms the anchovies from salty bites into a smooth, umami-rich paste that dissolves seamlessly into the dressing.
Use a fork to gently mash the anchovies and mustard together until completely broken down. I like to press the fork down firmly—this ensures every tiny piece dissolves. The texture should be completely smooth, with no visible anchovy bits remaining. This prevents graininess in your final dressing.
🍳 Step 2: Whisk in Vinegar and Honey
In a medium bowl, combine the 0.25 cup white wine vinegar and 1 tsp honey. Whisk vigorously for 30 seconds until the honey dissolves completely. The vinegar should look completely clear with no visible honey strands—this means it's properly emulsified and ready for the next ingredients.
Here's the thing—adding the honey at this stage balances the acidity of the vinegar while preparing the dressing for the oil. The slight sweetness will complement the umami from the anchovies later. If you notice any undissolved honey, whisk for another 10 seconds to ensure complete integration.
🥘 Step 3: Incorporate the Herbs and Cheese
Add the 0.25 cup finely chopped fresh tarragon leaves and 0.25 cup finely chopped fresh basil leaves to the vinegar-honey mixture. Stir gently with a wooden spoon to distribute the herbs evenly. Then, fold in the 0.25 cup freshly grated aged Parmesan cheese using a spatula.
I always use a spatula for this step because it helps scrape up any cheese that might stick to the bottom. The herbs should be finely distributed—no large clumps. The Parmesan should melt into the mixture rather than sit as separate crystals. This creates that signature creamy texture that makes this dressing special.
🍳 Step 4: Slowly Emulsify the Olive Oil
With the motor running on low speed, slowly drizzle in the 0.75 cup extra-virgin olive oil over 2-3 minutes. This gradual addition is critical—it allows the dressing to emulsify properly rather than separating. You'll see the mixture thicken gradually as the oil incorporates.
Don't rush this step. If you add the oil too quickly, the dressing will break and separate. The key is patience—let the emulsifiers (mustard and Parmesan) work their magic. You should end up with a thick, velvety dressing that coats the back of a spoon. If it looks too thin, add 1 tsp more Parmesan to help thicken it.
🔪 Step 5: Season and Adjust
Add the 0.5 tsp Diamond Crystal kosher salt and 0.25 tsp freshly ground black pepper to the dressing. Taste immediately—this is the only way to get it perfect. The anchovies should provide deep umami, the vinegar should have a bright tang, and the Parmesan should add a salty richness.
If needed, adjust the balance: add 1 tsp more honey for sweetness, 1 tsp more vinegar for acidity, or 1 tsp more Parmesan for saltiness. The dressing should be perfectly balanced—no single flavor should overpower the others. Once satisfied, transfer to a clean jar and let it sit for 30 minutes before using. This resting time allows all the flavors to meld completely.
Pro Tips For Making Assaggio House Salad Dressing
- Mash Those Anchovies: Crush the fillets flat with the back of a spoon before adding them—this breaks down the texture and lets the salt and umami melt into the dressing instead of sitting in stubborn chunks. I learned this the hard way after tasting a dressing where I’d just tossed them in whole.
- Warm the Vinegar First: Heat the white wine vinegar in a small saucepan for 10 seconds—just enough to wake up its acidity. Cold vinegar dulls the dressing; warm vinegar cuts through the richness of the olive oil and mustard like it’s supposed to. (Yes, even if you’re impatient like me.)
- Skip the Pulse for Tarragon: Finely chop the tarragon leaves by hand instead of blending—you’ll get brighter flavor and avoid the bitter, pulpy texture that comes from over-processing. A sharp knife and a cutting board take 30 seconds; a blender ruins the whole thing.
- Balance the Mustard Slowly: Start with half the Dijon mustard called for, taste, then add the rest if needed. Mustard can overpower the anchovies and tarragon if you dump it all in at once. I was skeptical until I tried it—now I never go back.
Pro cooking tips for great assaggio house salad dressing
Emulsification Mastery
The key to a silky, clingy dressing lies in the slow emulsification technique. Start by whisking the vinegar and honey vigorously for 30 seconds—this creates a stable base before adding oil.
When incorporating the 0.75 cup extra-virgin olive oil, drizzle it in thin streams while using an immersion blender on low speed for 2-3 minutes. The mustard and Parmesan act as natural emulsifiers, binding the oil and vinegar together. 💫
Anchovy Integration
Never skip the 5-minute anchovy softening step—this transforms the fillets into a smooth paste rather than visible bits. Use a fork to press firmly against the bowl, breaking down every fragment.
The result should be a completely homogeneous mixture. If you rush this, your dressing will have an unpleasant grainy texture that ruins the experience.
Herb Freshness Matters
Fresh herbs make all the difference—tarragon and basil should be chopped just before adding to preserve their vibrant flavors. Use a sharp chef's knife and cut them into tiny pieces (almost like confetti) for even distribution.
Pre-chopped herbs lose potency quickly, so skip the jarred versions. The aroma alone will tell you if they're fresh enough.
Parmesan Texture Secrets
For that signature creamy yet slightly gritty texture, use freshly grated aged Parmesan—pre-grated cheese contains anti-caking agents that make the dressing taste dull. Grate it yourself using a microplane or fine grater, then strain through a fine-mesh sieve to remove any large crystals.
This ensures a smooth emulsion without sacrificing that satisfying Parmesan crunch in every bite.
Resting for Flavor Fusion
After assembly, let the dressing rest for 30 minutes before using. This allows the flavors to meld completely and the emulsion to stabilize. I've learned the hard way—skipping this step means the anchovy and Parmesan flavors don't integrate properly, leaving a disjointed taste.
Trust the process, and you'll be rewarded with a dressing that tastes even better the next day.
Adjusting on the Fly
Taste as you go! If the dressing tastes too acidic, add 1 tsp more honey or a pinch of salt. Need more umami? Stir in ½ tsp extra anchovy paste. The beauty of homemade dressing is that you can tweak it until it's perfect for your palate.
Store leftovers in a clean, airtight jar in the fridge for up to 10 days—shake well before each use to redistribute the oil.
Nutrition facts
Frequently asked questions
Can I make this dressing without anchovies?
Yes! For a vegetarian version, replace the anchovies with 1 tbsp fish sauce or ½ tsp soy sauce to maintain umami depth. The dressing will still develop rich flavor, though the texture will be slightly lighter. If avoiding both, try 1 tsp nutritional yeast for a cheesy, savory note instead.
How do I fix separated dressing?
If your dressing separates, simply whisk vigorously or use an immersion blender to re-emulsify. Add 1 tsp Dijon mustard or ½ tsp Parmesan to help stabilize it. For stubborn separation, combine equal parts dressing and warm water, whisk until smooth, then gradually add cold water while whisking continuously.
Can I use dried herbs instead of fresh?
Fresh herbs are ideal for maximum flavor, but you can substitute with ½ tsp dried tarragon and ½ tsp dried basil (about 1/5 the fresh amount). Toast the dried herbs briefly in a dry pan to enhance their aroma before adding. The dressing will taste different but still delicious—just less vibrant.
What's the best way to store leftovers?
Transfer to a clean, airtight glass jar and store in the fridge for up to 10 days. Always shake well before using as the oil may separate. For longer storage, freeze in 1-tablespoon portions—thaw overnight in the fridge before using. The flavors actually improve after 24 hours of resting!
Is this dressing good for grain bowls?
This rich, umami dressing works beautifully on grain bowls, especially with quinoa or farro. The Parmesan crystals add texture contrast while the anchovy base complements roasted vegetables perfectly. Use it as a base or drizzle lightly—just 1-2 tablespoons per bowl goes a long way.
