A touch of toasted sesame oil and scallions at the end brings everything together with a nutty, fresh finish. Whether you're easing into a vegan diet or simply looking for a fast, flavorful dinner that happens to be good for your heart and blood sugar, this yaki udon delivers maximum comfort-food satisfaction with minimal effort.

Method

1. If using dried or semi-fresh udon, bring a large pot of water to a boil and cook noodles according to package directions until just tender. Drain in a colander and rinse briefly with cool water to stop cooking; set aside. If using pre-cooked vacuum-packed udon, simply loosen the noodles under warm water and set aside. 4:00
2. In a small bowl, whisk together the soy sauce, mirin, rice vinegar, maple syrup, and toasted sesame oil to make the glaze. Set aside.
3. Mince the garlic and ginger, slice the shiitake mushrooms, and slice the scallions, keeping the white and green parts separate. Crumble the tempeh into small, bite-sized pieces with your hands.
4. Heat 2 tablespoons of vegetable oil in a large nonstick skillet or wok over medium-high heat. Add the crumbled tempeh and spread into an even layer. Cook undisturbed for 2-3 minutes, then stir and continue cooking until golden and crisp on most sides, about 5-6 minutes total. 6:00
5. Push the tempeh to one side of the skillet, add the remaining tablespoon of oil, and add the sliced shiitake mushrooms. Saute for 3-4 minutes until softened and browned. 4:00
6. Add the minced garlic, ginger, and the white parts of the scallions to the skillet. Stir everything together and cook for 30-60 seconds until fragrant. 1:00
7. Add the cooked udon noodles to the skillet along with the soy-mirin glaze. Toss everything together using tongs or a spatula until the noodles are evenly coated and heated through, about 2-3 minutes. 3:00
8. Add the baby spinach and red pepper flakes, if using, and toss just until the spinach wilts into the noodles, about 1-2 minutes. 1:30
9. Remove the skillet from the heat and divide the yaki udon among bowls. Garnish with the reserved green scallion parts and toasted sesame seeds before serving hot.
