What makes this dish special
The first time I tried dan dan noodles in Los Angeles, I was not impressed. It wasn't until I flew across the world to Taiwan and tried their dan dan noodles that I was blown away. Turns out the first one I had was a fraud, a noodle dish attempting and failing miserably to be dan dan noodles. The true noodle dish is bursting with umami and spicy yet still balanced with a little sweetness.
Inspired by these noodles, I made a very loosely based version. These sesame chili udon noodles are reminiscent of dan dan noodles but have a savory crumbled tofu topping, crushed peanuts, and pickled cucumbers to tie it all together. It's not traditional, but it's pretty darn delicious.
Since dan dan noodles are usually vegetarian, I also decided to make my sesame chili udon noodles vegetarian. However, I have seen some versions with crumbled pork, so I topped my dish with crumbled tofu. It's like the best of both worlds, you get a protein, but it's still vegetarian.

Add back tofu along with Shaoxing wine, soy sauce, hoisin, sugar, and five spice powder. Mix to combine and simmer for 2 minutes. Season with salt and pepper and keep warm.
- Make sauce for noodles. Whisk together boiling water with chili oil, sesame paste, soy sauce, sugar, and Sichuan peppercorns until well combined.
- Cook udon noodles according to directions on package. Drain and immediately add as much as sauce as you like, stirring to combine.
- Portion noodles into bowls and top with crumbled tofu. Garnish with pickled cucumber, chopped peanuts, and cilantro. Serve immediately.
Notes
Step-by-step instructions
Step 1: Pickle the cucumbers
The noodles come together fairly quickly, so let's start with the item that takes the longest, the pickled cucumbers. Combine boiling water with rice vinegar, sugar, and salt, stirring until the sugar dissolves.
I always use boiling water to speed up the process.

Add the sliced cucumbers and let them sit for at least 30 minutes or overnight. Keep in mind that if you slice the cucumbers too thickly, they will take longer to pickle.
Step 2: Prepare tofu topping
Next, make the crumbled tofu. To get the best texture, use extra-firm tofu if possible. Drain the tofu and wrap it in paper towels. Place a weight on top of the tofu, like a small Pyrex container, and let it sit for 10 minutes. You want to drain as much of the water as possible.
Then, crumble the protein into small chunks so that it almost looks like ground meat (the operative word being "almost").

Heat oil in a saute pan and cook the tofu, letting it sit undisturbed for five minutes so that it can get nice and golden brown.
Once the tofu is browned, remove it from the pan and move on to the mushrooms. Finely chop the mushrooms either by hand or with the help of a food processor.

Then, saute the mushrooms until browned. Add back the tofu along with all of the seasonings and stir everything together.
For the seasonings, if you can't find Shaoxing wine, substitute it with sherry wine.

Keep the savory topping warm while you prepare the rest of the dish.
Step 3: Cook noodles
For the sauce, combine boiling water with sesame paste, chili oil, soy sauce, sugar, and ground Sichuan peppercorns until well mixed. I used S&B chili oil with crunchy garlic, which is mild chili oil. However, you can use any other type of chili oil.
For the sesame paste, I used Wang Zhihe Pure Sesame Paste, but you can also use tahini, which is also made from sesame seeds.

Cook the udon noodles according to the directions on the package and drain well. Toss the noodles with the sauce - go generous, it adds all the flavor - and top with the crumbled tofu, crushed peanuts, cilantro, and pickled cucumbers.
I didn't tell my husband at first that these sesame chili udon noodles were based on dan dan noodles. The original Chinese noodles are one of his favorite dishes, so I didn't want to disappoint him with my version. Luckily, he thoroughly enjoyed this dish, and I did as well!

- Make-ahead: The pickled cucumbers and sauce for the noodles can be prepared the day before. You can also cook the crumbled tofu the day before, and reheat it before serving.
- Store: Keep leftovers in an airtight container in the refridgerator for up to 4 days.
