Bring a large pot of water to a rolling boil. Cook the ramen noodles according to package directions until tender, about 3-5 minutes. Drain well.
Meanwhile, heat a large skillet over medium-high heat. Add 6 tablespoons of salted butter and 4 cloves of minced garlic. Cook, stirring occasionally, until the garlic turns golden and caramelized, about 2-3 minutes. Stir in 2 teaspoons of grated ginger and cook for another minute.
Add the grated zucchini to the skillet and cook for 2-3 minutes, stirring, until the zucchini has wilted into the garlic butter sauce.
Add the drained ramen noodles, 1/4 cup of soy sauce, and 1/2 cup of fresh basil to the skillet. Gently toss all the ingredients together to combine evenly. Remove the skillet from the heat immediately.
Divide the garlic butter ramen noodles among individual serving bowls. Top each bowl with toasted sesame seeds and, if desired, a soft-boiled or fried egg. Serve and enjoy immediately!
