Make the Gochujang Sauce:In a small bowl, whisk together 2 tbsp gochujang, 1 tbsp low-sodium soy sauce, 1 tbsp brown sugar, 1 tsp white miso paste (optional), 1 tsp rice vinegar, and 1 tsp sesame oil. Set the sauce aside.
Sauté the Vegetables:Heat a 12-inch cast iron skillet (or large sauté pan) over medium-high heat. Add 2 tbsp of salted butter and let it melt. Once melted, add ½ cup diced yellow onion and sauté for about 1-2 minutes until softened.
Add Carrot, Edamame, Ginger, and Garlic: Stir in ½ cup shredded carrot, ½ cup shelled edamame, 2 tsp minced ginger, and 2 tsp minced garlic. Sauté for another 2-3 minutes, until the vegetables are tender and fragrant.
Incorporate the Rice: Add 3 cups of cooked jasmine rice to the pan. Stir to combine everything and ensure the rice is fully incorporated with the vegetables. Turn the heat to high.
Flatten and Sear the Rice: Flatten the rice into an even layer in the pan. Let it cook undisturbed for about 2 minutes to create a crispy texture on the bottom. Flip the rice, flatten it out again, and cook for another 2 minutes.
Scramble the Eggs: Push the rice to one side of the pan. Add the remaining 1 tbsp of salted butter to the empty side and pour in ¾ cup egg alternative. Quickly scramble the eggs, breaking them up as they cook. Once they are no longer liquid, mix them into the rice.
Add the Sauce and Cashews: Pour the prepared gochujang sauce over the rice, and toss everything together until well coated. Add 2-3 tbsp roasted or raw cashews and continue mixing until combined. Adjust salt as needed based on taste.
Serve: Serve immediately, and garnish with chopped green onions, sesame seeds, and a drizzle of spicy sesame oil if desired.
