Bring a large pot of salted water to a boil for the pasta.
Prepare ingredients: chop garlic, chili, parsley, and crush stale bread into coarse crumbs.
Pat scallops dry between paper towels and season with salt and pepper.
Preheat two sauté pans over low heat for about 3 minutes.
Cook pasta in salted water, setting a timer for 1 minute less than the package instructions. Stir once every minute.
When pasta has cooked about 5 minutes, heat 3 Tbsp olive oil in one pan and add scallops. Sear without moving for 3-4 minutes.
Flip scallops and cook about 90 seconds more. Remove them to a paper towel-lined plate.
In the second pan heat 1/4 cup olive oil. Add anchovies, garlic, and chili and cook until fragrant.
When garlic begins to turn lightly golden, add parsley and about 1/4 cup pasta water.
Drain pasta when al dente and add it to the sauce with breadcrumbs and reserved anchovy liquid.
Toss well and adjust seasoning with salt and pepper if needed.
Twirl pasta into bowls and arrange scallops around the pasta. Spoon pan juices over the scallops.
