Ingredients for arigatos white sauce
Nine simple ingredients blend into restaurant-quality richness—no cooking required.
| Ingredient | Amount | Notes |
|---|---|---|
| Raw Cashews 🥜 | 1 cup | Unsalted, roasted for depth |
| Raw Almonds 🌰 | ½ cup | Unsalted, lightly toasted |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity variety |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed, strained |
| White Miso Paste 🍶 | 1 tbsp | Aged 2-3 years for umami |
| Sesame Oil 🫒 | 1 tsp | Toasted, for nutty aroma |
| Pure Maple Syrup 🍯 | 1 tbsp | Grade B for depth of flavor |
| Ground White Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain, for balanced seasoning |
| Filtered Water 💧 | ¼ cup | Room temperature |
The nuts are the heart of this sauce. Trader Joe's has the best-priced raw cashews and almonds in bulk bins—look for organic if you prefer. Toasting them lightly in a dry pan (just until fragrant) deepens their flavor without burning. White miso is key for that authentic umami—Miso Master brand is my go-to, but any aged 2-3 years works. The olive oil should be extra-virgin; California-based brands like Corto or Filippo Berio have the best balance of fruitiness and smoothness for this application. If you're short on time, skip toasting the nuts and just blend them raw—the sauce will still be creamy, just slightly less complex.
No white miso? Substitute with 1 tbsp vegan mayo plus 1/2 tsp nutritional yeast for umami, though it won't be identical. Swap sesame oil for toasted walnut oil at half the amount if you're avoiding sesame. The maple syrup can be swapped for agave nectar or date syrup, but maple's caramel notes complement the nutty profile perfectly. For a tangier sauce, add an extra tablespoon of lemon juice—just taste as you go. The water is just to help emulsify; if your blender is powerful, you can reduce it to 2 tablespoons. And if you're out of kosher salt, fine sea salt works 1:1.
This sauce keeps beautifully in an airtight jar for 7-10 days in the fridge—it actually tastes better as the flavors meld. For longer storage, freeze in 1-tablespoon portions (perfect for single use). Thicken it by chilling, or thin with a splash of water or plant milk if needed. The lemon juice means it won't curdle, so it's stable for reheating. I like to portion mine into small ramekins for easy grab-and-go drizzling over salads or grains. If it separates slightly after blending, just pulse again—it'll come back together.
Why You'll Love This Recipe
- Five-Ingredient Magic: I swear, this sauce comes together with just five things—no blender wars, no measuring chaos. Soak the nuts overnight (or pulse them dry if you’re impatient), then toss in olive oil, lemon, and miso. That’s it. No stress, no fuss, just smooth perfection in minutes.
- Umami-Packed Punch: Between us, white miso brings the flavor—salty, deep, and addictive in the best way. The raw nuts add creaminess without heaviness, while the lemon keeps it bright. It’s like a hug for your taste buds, but make that a savory hug.
- Sauce for Everything: Slather it on roasted veggies, drizzle it over noodles, or use it as a dip for crudités. It’s my go-to for weeknight dinners, potlucks, or even as a quick marinade. Honestly, I’ve lost track of how many ways I’ve repurposed this stuff—and it never lets me down.
- Budget-Friendly Luxury: Cashews and almonds stretch further than you’d think, and a little miso goes a long way. No fancy ingredients here, just smart swaps that taste like you spent hours in the kitchen. Plus, it keeps for days in the fridge, so you’re not scrambling to use it up.
Step-by-step instructions for Arigatos white sauce
Here's the no-cook method for velvety, nutty perfection—no stove required.
👨🍳 Step 1: Toast the Nuts for Maximum Flavor
Preheat your oven to 350°F and spread the 1 cup raw cashews and 0.5 cup raw almonds on a baking sheet in a single layer. Toast for 8-10 minutes until fragrant and just beginning to turn golden. Watch closely—they'll darken quickly after that initial color change.
This step builds depth of flavor that raw nuts can't provide. I like to shake the pan every 2-3 minutes to ensure even toasting. Remove from the oven and let cool for 5 minutes before processing—warm nuts release more oil during blending, which helps create that signature creamy texture.
🥘 Step 2: Blend the Base Ingredients
Transfer the toasted nuts to a high-speed blender along with the 0.5 cup extra-virgin olive oil, 2 tbsp lemon juice, 1 tbsp white miso paste, 1 tbsp pure maple syrup, 0.25 tsp ground white pepper, and 0.5 tsp diamond crystal kosher salt. Blend on high for 1-2 minutes until completely smooth, stopping to scrape down the sides as needed.
The miso paste is where the magic happens—it adds that unmistakable umami depth while keeping the sauce light. Here's the thing: the sauce should look like thick, pale yellow paint at this stage. If it's too thick, add 1 tablespoon of the 0.25 cup filtered water and blend again. If it's too thin, add another 1 tablespoon of toasted nuts and blend until smooth.
🍳 Step 3: Finish with Sesame Oil for Nutty Depth
With the blender running on low speed, slowly drizzle in the 1 tsp sesame oil through the feed tube. This gradual addition prevents the sauce from breaking and ensures even distribution of that toasty, nutty aroma. Taste and adjust seasoning—you might need a pinch more salt or a splash more lemon juice to balance the flavors.
Here's where it gets interesting: the sesame oil doesn't just add flavor—it creates that signature sheen and subtle nuttiness that makes this sauce stand out. For the smoothest texture, strain through a fine-mesh sieve into a clean jar if you prefer a completely silky finish. The sauce will keep in the refrigerator for up to 5 days, or you can freeze it for 3 months.
⏰ Step 4: Rest and Use for Perfect Consistency
Let the sauce sit at room temperature for 10-15 minutes before using. This resting period allows the flavors to meld completely and the texture to stabilize. You'll notice it becomes slightly thicker as it cools—this is normal and actually improves the sauce's clinging ability when used on dishes.
For best results, whisk vigorously before each use to re-emulsify any separated oils. This sauce works beautifully as a drizzle for noodles, a dressing for salads, or even as a creamy base for dips. The lemon juice keeps it bright while the miso and maple syrup create that perfect balance of sweet, salty, and umami that makes this sauce so versatile.
Pro Tips For Making Arigatos White Sauce
- SOAK NUTS 4+ HOURS: I learned this the hard way—skipping the soak or rushing it with hot water leaves you with a gritty, unblended mess. Cold water for 4+ hours (or overnight) guarantees smoothness, even with raw cashews and almonds.
- USE MISO LAST: Add the white miso paste after blending the nuts, oil, and lemon—mixing it in early can turn your sauce bitter. Stir it in at the end and let it bloom for 30 seconds for that deep umami kick without overpowering.
- BLEND IN BATCHES: If your blender struggles, split the soaked nuts into two rounds. Overloading it means you’ll burn out the motor and end up with a lumpy sauce. Start with half, then add the rest once it’s smooth.
- LEMON JUICE FIRST: Add the lemon juice before the olive oil—it emulsifies better that way. I was skeptical until I tried it: the acid cuts through the richness, and the sauce stays silky instead of separating. (Yes, even if you’re impatient like me.)
Storing and reheating your leftovers
Fridge Storage Tips
Store your Arigatos white sauce in an airtight glass jar—I love using Le Parfait containers with snap-on lids for easy access.
Keep it refrigerated at 40°F or below for up to 7-10 days, though I find the flavors actually deepen after 3-4 days as the miso and maple syrup meld together.
The sauce will thicken slightly when chilled, which is perfect for drizzling—just whisk before using to restore its silky texture. 💛
Freezer Preservation
For longer storage, freeze the sauce in 1-tablespoon portions using silicone mini molds or ice cube trays. Transfer to a freezer bag and label with the date—it stays fresh for 3 months without losing quality.
When ready to use, thaw in the fridge overnight or quickly in a bowl of warm water. The texture remains stable, though you may need to whisk briefly to re-emulsify any separated oils.
Reheating Methods
This sauce reheats beautifully—simply stir 1-2 tablespoons into a small saucepan with 1 tablespoon water and warm over low heat for 2-3 minutes. Avoid high heat, as it can break the emulsion and make the sauce separate.
For microwave reheating, use 30-second intervals on 50% power, stirring between each interval until fully warmed. The lemon juice prevents curdling, so you won’t lose that bright, creamy quality.
Texture Adjustments
If your sauce thickens too much after refrigeration, thin it with 1 teaspoon water or plant-based milk at a time until you reach your desired consistency. For a thicker version, simply chill it longer—it will naturally firm up.
If the sauce separates slightly, don’t panic! Just blend or whisk vigorously for 10-15 seconds to restore its smoothness. The sesame oil and olive oil blend back together beautifully with a little effort.
Portioning for Convenience
I like to portion my sauce into small ramekins or shot glasses for easy grab-and-go use. These make perfect single-serving drizzles for salads, noodles, or grilled proteins. Store them in the fridge, and they’ll keep for up to 5 days without needing to open the whole jar.
This method also makes it easy to experiment with different flavor variations—just keep a few ramekins on hand for quick adjustments.
Long-Term Flavor Stability
The white miso and maple syrup act as natural preservatives, helping the sauce maintain its rich, umami flavor even after storage. That said, for the best results, use it within 10 days of making it.
If you notice the sesame oil separating to the top, simply give it a good shake before using—it’ll blend right back in. The sauce’s bright lemon note ensures it stays fresh-tasting, unlike dairy-based sauces that can develop off-flavors over time. ✨
Nutrition facts
Frequently asked questions
Can I make this white sauce without toasting the nuts?
Yes, but the flavor will be less complex. Toasting the nuts enhances their natural oils and deepens their flavor, which is key to the sauce's richness. If you skip toasting, blend the raw nuts with an extra 1 tablespoon olive oil to compensate for the lost depth. The texture will still be creamy, but the nutty aroma will be subtler.
What if I don't have white miso paste?
No problem! For umami depth, substitute with 1 tbsp vegan mayo plus ½ tsp nutritional yeast. If you're avoiding mayo, try 1 tsp soy sauce or coconut aminos instead. The sauce will still taste delicious, though the flavor profile will shift slightly away from the traditional miso richness.
How can I make this sauce thicker or thinner?
To thicken, simply chill the sauce for 30 minutes—it naturally firms up. For a thinner consistency, add 1 tsp water or plant-based milk at a time while whisking. If the sauce separates after refrigeration, blend or whisk vigorously for 10-15 seconds to restore its smooth texture.
Is this sauce vegan?
This recipe is completely plant-based, relying on nuts, oils, and natural sweeteners instead of dairy or animal products. The white miso and maple syrup ensure it’s vegan-friendly while delivering that creamy, umami-rich flavor you’d expect from a traditional white sauce.
Can I use this sauce on hot dishes?
Yes, but add it at the end of cooking to preserve its texture. The sauce reheats well, but high heat can cause separation. For best results, drizzle it over dishes after they're served or warm it gently on low heat for 1-2 minutes while stirring constantly.
