The Story Behind Thanh Long Restaurant
San Francisco Roots
The Thanh Long garlic noodles recipe didn’t come from a traditional Vietnamese cookbook. Rather, it began in the kitchen of Thanh Long, a family-run eatery that soon rose to fame in the neighborhood, in San Francisco in the 1970s. The dish was created by Helene An, the chef known as the “mother of fusion cuisine,” who blended Vietnamese techniques with Western ingredients in creative, unexpected ways.
Chef Helene An and the Crustacean Legacy
Over time, this buttery garlic noodle dish became the restaurant’s most talked-about item. When the An family opened Crustacean, their upscale spin-off restaurant, they carried the recipe with them. People came not only for the seafood, but also for the addictive noodles served on the side. The thanh long garlic noodles recipe may seem simple, but it’s layered with decades of culinary history and cultural fusion — and that’s what makes it unforgettable.
Key Ingredients in This Garlic Noodle Recipe
Here’s what you’ll need to make this rich and flavorful thanh long garlic noodles recipe:

Ingredients
- ½ tsp, Ground black pepper
- 12 oz, Fresh egg noodles (or use spaghetti if needed)
- 5 tbsp, Unsalted butter
- 6 cloves, Garlic, finely minced
- 1 tbsp, Oyster sauce
- 1 tbsp, Soy sauce

Best Noodle Choices for This Dish
Traditionally, this dish is made with fresh wheat noodles, but if you can’t find them, don’t worry. Regular spaghetti or linguine works just fine. What matters most is that the noodles are firm and slightly chewy — they need to hold up under the thick sauce.
The innovation is that the dish is finished with a little grated Parmesan cheese. The nutty, salty flavor may seem out of the ordinary, yet it unifies everything and gives depth. That’s the beauty of the thanh long garlic noodles recipe — it’s a fusion dish that breaks the rules and still comes out delicious.
Step-by-Step Cooking Instructions
Prepping the Ingredients
To guarantee a seamless cooking experience, collect all of your items before you begin. For the thanh long garlic noodles recipe, you’ll need:
- Noodles: Fresh egg noodles are ideal, but spaghetti works well too.
- Garlic: Mince it finely to release its full flavor.
- Butter: With unsalted butter, you can regulate the amount of salt.
- Sauces: Oyster sauce, soy sauce, and a touch of fish sauce provide umami depth.
- Sugar: A small amount balances the savory elements.
- Parmesan Cheese: Adds a nutty finish.
- Scallions: For garnish and a fresh bite.
Before you start cooking, make sure all the ingredients are prepped and measured.
Making the Sauce and Noodles
- Noodles should be cooked by boiling them as directed on the package until they are al dente. After draining, set away.
- To make the sauce, melt the butter in a big skillet over a medium heat. Add the minced garlic and cook for about 30 seconds, or until fragrant.
- Add Sauces: Stir in the oyster sauce, soy sauce, fish sauce, and sugar. To blend the flavors, thoroughly mix and simmer for one minute.
- Combine Noodles and Sauce: Add the cooked noodles to the skillet. Toss them in the sauce until they’re evenly coated and heated through.
- Finish with Cheese: Sprinkle grated Parmesan over the noodles and toss again to combine.
- Garnish and Serve: Serve right away after garnishing with chopped scallions.
This method ensures that each strand of noodle is infused with the rich, garlicky sauce, delivering the authentic taste of the thanh long garlic noodles recipe.
Cooking Tips & Substitutions

Avoiding Common Mistakes
To perfect the thanh long garlic noodles recipe, consider these tips:
- Don’t Burn the Garlic: Sauté just until fragrant to prevent bitterness.
- Use Fresh Ingredients: Fresh garlic and quality sauces make a significant difference.
- Balance the Flavors: Taste the sauce before adding noodles to adjust seasoning as needed.
Substitutions for Dietary Needs
If you have dietary restrictions, here are some substitutions:
- Vegetarian: Replace oyster and fish sauces with mushroom sauce or a combination of soy sauce and a dash of hoisin.
- Gluten-Free: Swap out the soy sauce for tamari and use gluten-free noodles.
- Dairy-Free: Substitute butter with plant-based alternatives and omit the Parmesan or use a dairy-free cheese.
By making these adjustments, you can enjoy a version of the thanh long garlic noodles recipe that suits your dietary preferences without compromising on flavor.
Serving Suggestions
Pairing with Proteins like Crab, Shrimp, or Tofu
One of the best things about the thanh long garlic noodles recipe is how well it pairs with other dishes. Traditionally, it’s served with roasted Dungeness crab, but you don’t have to stop there. Grilled shrimp, pan-seared scallops, or even crispy tofu make excellent additions. These proteins absorb the sauce beautifully and turn the dish into a full meal.
Simple Side Dish Ideas
To round out your meal, try something light and fresh. A simple cucumber salad, sautéed bok choy, or steamed edamame can balance the rich flavors of the noodles. If you prefer something heartier, garlic bread or a side of stir-fried veggies can work too. No matter what you pair with it, this thanh long garlic noodles recipe will shine as the centerpiece.
Storage and Reheating
How to Store Leftovers Properly
If you happen to have leftovers, let the noodles cool first. After that, store them in the refrigerator for up to three days in an airtight container. The flavors will continue to develop, making the next day’s bite just as satisfying.
Best Way to Reheat Without Losing Flavor
To reheat, use a nonstick skillet over medium heat. Add a splash of water or a tiny bit of butter to loosen the noodles as they warm. Stir often to avoid sticking. Microwaving works too, but be sure to cover the noodles and stir halfway for even heating. This way, your thanh long garlic noodles recipe stays delicious even the next day.
FAQs
Q: What Type of Noodles Did Thanh Long Use?
Originally, Thanh Long used fresh egg noodles, which are chewy and soak up sauce really well. But if you can’t find them, don’t worry. Spaghetti, linguine, or even ramen noodles make great substitutes. Just be sure not to overcook them, so they hold their texture in the sauce.

Definitely. You can make the sauce ahead and store it in the fridge for up to three days. Just reheat it gently before tossing with fresh noodles. This trick is great for saving time during busy weeknights.

It’s very similar. Crustacean is owned by the same family as Thanh Long, and they use a nearly identical noodle recipe. While their full version is a secret, this homemade thanh long garlic noodles recipe gets incredibly close to the real thing.
