1 tablespoon good-quality vegetable oil, plus more if needed
1 teaspoon sesame oil, plus more if needed
2ounces boneless beef sirloin, cut into bite-size pieces
1/2 large carrot, julienned or minced
1/2 small onion, thinly sliced and separated into rings
4 scallions, chopped
2ounces fresh spinach (or more if you like)
2ounces mushrooms, trimmed (preferably a mixture of oyster, shiitake, and enoki)
2 teaspoons chopped garlic
2ounces Korean sweet potato vermicelli or bean threads
2 teaspoons soy sauce, plus more to taste
1 tablespoon pine nuts, lightly toasted
1/4cup sesame seeds, lightly toasted
Instructions
Bring a medium saucepan of water to a boil and salt it. Put 1 tablespoon of vegetable oil and the sesame oil in a medium skillet over medium-high heat. When they’re hot, add the meat, sprinkle with salt and pepper, and cook, stirring occasionally, until browned, about 5 minutes. Transfer with a slotted spoon to a serving bowl. Cook the carrots in the same skillet, stirring occasionally, until they lose their crunch, about 3 minutes. Add to the meat.
Return the pan to medium-high heat and add the onion; cook, stirring occasionally, until it begins to brown, about 3 minutes. Transfer to the bowl with the carrots and meat. Raise the heat to high and add the scallions. Cook, stirring, until they soften, 2 to 3 minutes. Add to the bowl.
Add a little more vegetable and sesame oils to the skillet if necessary and stir-fry the spinach over medium heat until it softens, a minute or 2. Sprinkle with a little salt and add it to the bowl. Add the mushrooms and garlic to the pan and cook, stirring occasionally, until they soften, about 5 minutes. Add to the bowl.
Add the noodles to the boiling water and turn off the heat. Let them soak, stirring a couple times, until the noodles are tender but not mushy; start tasting after 3 minutes. Drain the noodles and add them to the bowl, along with the soy sauce. Toss until thoroughly combined, adding salt, pepper, and more sesame oil and/or soy sauce to taste. Garnish with the pine nuts and sesame seeds and serve at room temperature
