Make the roasted garlic
Preheat the oven to 400°F. Cut the top ¼ inch off two heads of garlic. Drizzle with 2 tablespoons olive oil and sprinkle with salt. Wrap in foil, set on a
sheet pan, and roast for 45 minutes to 1 hour, or until soft and caramelized. (The garlic is done when a center clove is completely soft when pierced with a paring knife.) Let the garlic cool slightly, then squeeze from the bottom of the bulb to push the cloves out of their paper into a bowl.
Make the crispy garlic garnish
For easy-to-peel garlic, add the remaining unpeeled head of garlic to a microwave-safe small bowl. Cover with cold water and microwave for 30 seconds to 1 minute. Carefully remove from the hot water and chop off the bottom (root end) of the bulb. The cloves should immediately separate and peel easily without any sticky, papery mess.
Roughly chop the garlic using a knife or food processor. Add ¾ cup neutral oil and the chopped garlic to a small
saucepan. Place over medium-high heat and cook, stirring, until the mixture begins to bubble, about 3 minutes. Continue cooking, stirring frequently and scraping down the sides to prevent sticking, until the garlic turns pale golden brown, 6–8 minutes longer. Immediately remove from the heat and strain into a fine-mesh sieve over a bowl—if you wait, it will overcook.
Let the crispy garlic drain on a paper towel–lined plate. Once cooled, store the garlic oil separately in a jar or resealable container in the fridge for up to 3 weeks. (It will solidify when chilled; bring to room temperature or gently heat to use.)
Cook the shrimp
While the garlic is roasting, heat a
wok or
large skillet over medium heat. Season the shrimp with 1 tablespoon garlic oil, 1 teaspoon kosher salt, ¼ teaspoon white pepper, and ¼ teaspoon Chili Garlic seasoning, if using. Add another tablespoon of garlic oil to the skillet, add the shrimp in a single layer, and cook for 2 minutes. Flip and cook for another 2 minutes, or until pink and opaque, working in batches if needed. Transfer the shrimp to a plate and set aside. Wipe out the skillet to finish the dish.
Make the sauce
Smash the roasted garlic with a fork, then add the oyster sauce, soy sauce, brown sugar, Maggi seasoning, fish sauce, sesame oil, and Chili Garlic sauce. Stir to combine and set aside.
Finish the noodles
Boil the noodles according to package directions. (Fresh noodles take 2–5 minutes; dried noodles take 8–10 minutes.) Heat the same skillet or wok over medium heat and melt the butter. Add the noodles and toss so every strand is coated. Let sit and crisp for 3 minutes. Add the sauce and toss thoroughly, then add the shrimp and toss again. Garnish with crispy garlic and cilantro and serve.
