Step‑by‑Step Instructions for Vegan Sesame Yaki Udon Noodles
Step 1: Prepare the Protein
Begin by preparing your protein of choice for the Vegan Sesame Yaki Udon Noodles. If opting for homemade seitan, follow your preferred recipe to achieve strips or bites. Alternatively, marinate and bake tofu in the oven at 400°F for 25-30 minutes until golden. Set aside your protein while you move on to the next steps, ensuring everything is ready for a delightful stir-fry.
Step 2: Sauté the Aromatics
In a large skillet or wok, heat 2 tablespoons of sesame oil over medium heat. Once the oil shimmers, add one chopped yellow onion and sauté for 5 minutes until it turns translucent and fragrant. This step lays a flavor foundation for your Vegan Sesame Yaki Udon Noodles, inviting in the sweetness that onion brings to this savory dish.
Step 3: Cook the Vegetables
Add broccolini or your choice of seasonal vegetables to the skillet, followed by 2-3 tablespoons of water. Stir well and cover, allowing the mixture to cook for 6-8 minutes, until the vegetables soften and the water evaporates. This quick steam helps preserve the vibrant green color and nutrients, preparing the veggies to complement the chewy udon noodles.
Step 4: Prepare the Sauce
In a small bowl, combine soy sauce, agave nectar, and sambal oelek to create a luscious sauce. If using cornstarch for thickness, mix 1 tablespoon of it with a couple of tablespoons of the sauce to form a slurry. Set both the sauce and the slurry aside, as they will bring the Vegan Sesame Yaki Udon Noodles to life in the next steps.
Step 5: Add the Udon Noodles
Gently add your fresh udon noodles to the skillet, carefully folding them in with the sautéed vegetables. Cover the skillet and let it steam for 2-3 minutes, allowing the noodles to loosen and absorb some of the existing flavors. Afterward, toss the noodles with half of your prepared sauce, ensuring every strand is coated in deliciousness.
Step 6: Combine Protein and Sauce
Stir in the sautéed seitan or baked tofu, along with the remaining sauce and cornstarch mixture. Cook for another 3-4 minutes over medium heat, stirring frequently until the sauce thickens and clings beautifully to the vegan noodles. This step enhances the overall flavor profile of your Vegan Sesame Yaki Udon Noodles, making everything come together in harmony.
Step 7: Serve and Garnish
Once the sauce has reached your desired consistency, remove the skillet from heat. Transfer the indulgent Vegan Sesame Yaki Udon Noodles to bowls and garnish generously with chopped cilantro, sliced green onions, and a sprinkle of sesame seeds. These finishing touches burst with flavor and texture, readying your delightful meal for enjoyment.
