Bring a large pot of salted water to a rolling boil. Once bubbling, add the linguine and cook according to the package instructions until al dente. Make sure not to overcook it; nobody wants mushy pasta! Reserve a cup of the pasta water before draining. This liquid will help adjust the sauce's consistency later.
While the pasta cooks, heat the olive oil in a large skillet over medium heat. Add the whole garlic cloves, letting them sizzle and infuse the oil for around 2 minutes. Your kitchen will start to smell heavenly. Next, toss in the chopped anchovies, stirring until they melt into the oil. This method helps release their flavor without overwhelming the dish.
Now it’s time for chili peppers, capers, and diced tomatoes. Stir everything together and let it bubble gently. Season with oregano, sea salt, and black pepper. Let this simmer for about 10 minutes. Allowing the flavors to meld beautifully is key; patience makes perfect!
Once the sauce has thickened a bit, return to the reserved pasta water. Toss in the drained linguine, stirring to coat every strand thoroughly. You can add a bit more pasta water if it looks dry.
Finally, fold in the sliced Kalamata olives and chopped parsley. This provides an extra layer of color and flavor. Mix it gently, ensuring all components are well-distributed.
Serve immediately, garnishing with more parsley and a drizzle of olive oil if desired. Enjoy every mouthful!
