Get a big pot of water boiling. Toss in some salt. A simple rule of thumb is 1 liter of water and 10 g of coarse salt for every 100 g of pasta. Add the pasta to the boiling water and cook it following the packet's instructions, roughly 12 minutes. When it's ready, save 1 cup (250 ml) of the starchy cooking water, then drain the rest.

While the pasta cooks, pat the scallops dry with paper towels to remove excess moisture. Season both sides with salt and pepper. Heat 2 tablespoons of olive oil in a wide skillet over medium-high heat. Place the scallops into the hot pan, leaving a little space (about 2.5 cm) between each one to avoid crowding. If needed, cook them in batches. Let them brown on the bottom, about 2 minutes, then flip. If they stick, let them cook a few seconds longer before flipping. Once done on both sides, remove them from the pan and keep them aside.

In the same pan, turn the heat down to low. Add the remaining olive oil or butter, followed by the minced garlic. Stir gently as it cooks for about 1 minute. Then toss in the parsley and keep stirring for another minute.

Put the scallops back into the skillet. Stir so they soak up the garlic and parsley flavors. Add the pasta along with a splash of the starchy water (about 1/4 cup). Mix just enough to warm everything through. If it seems dry, add a bit more of the reserved cooking water.
