Creating Creamy Gochujang Pasta with Tofu is simple! Follow these steps for a delicious outcome:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve 1 cup of pasta water, then drain and set aside.
2. Prepare the Tofu: In a skillet over medium heat, add vegetable oil. Once hot, add the cubed tofu and sauté until golden brown on all sides, about 5 minutes. Remove the tofu from the skillet and set aside.
3. Sauté the Aromatics: In the same skillet, add minced onion and garlic. Sauté until the onion becomes translucent and fragrant, about 3-4 minutes.
4. Create the Sauce: Add gochujang to the skillet. Stir until well combined with the onions and garlic. Gradually pour in the heavy cream while stirring to create a smooth sauce.
5. Flavor the Sauce: Add soy sauce, sesame oil, and sugar (if using) to the sauce. Mix well and let the sauce simmer for 2-3 minutes.
6. Combine Everything: Add the cooked pasta and sautéed tofu to the skillet. Toss everything together, adding reserved pasta water gradually until you reach your desired sauce consistency.
7. Season: Taste and adjust with salt and pepper if necessary.
8. Garnish: Serve hot, garnished with chopped green onions and sesame seeds.

These steps will guide you in creating a delicious, creamy, and spicy meal that will impress everyone at your table.
