Cook spaghetti, or noodle of choice. Drain and set aside in a large bowl.
1 pound spaghetti
Add sesame oil, avocado oil, and red pepper chili flakes to a saucepan over medium heat. Cook for just a few minutes or until the chili flakes begin to pop. The longer the chili flakes pop, the spicer the noodles will be.
1/2 cup sesame oil, 1/3 cup avocado oil or canola oil, 2 tsp. red pepper chili flakes
Turn the heat down to low and add the soy sauce, honey, chili garlic sauce, and rice vinegar. Stir and bring the sauce to a simmer.
1/2 cup soy sauce, 1/3 heaping cup honey, 2 Tbsp. chili garlic sauce, 2 tsp. rice vinegar
Optional to thicken the sauce add in cornstarch slurry: Start with 1 Tbsp. cornstarch mixed with 1 Tbsp. water and whisk into sauce. You will notice the consistency change. If you want it thicker, add more cornstarch slurry. I don't like my sauce very thick (but that's up to you!)
1 Tbsp. cornstarch + 1 Tbsp. water
Combine the cooked noodles with the sauce.
Add in the peanuts, cilantro, green onions, and sesame seeds. Toss to combine. Garnish with more sesame seeds and green onions. Taste and adjust any seasonings to taste. Enjoy warm or chilled!
3/4 cup unsalted roasted peanuts, chopped, 1/2 cup fresh cilantro, chopped, 1/2 cup green onions, chopped, 2 Tbsp. toasted sesame seeds
