Bring a large pot of salted water to a boil and cook the pappardelle according to package directions until al dente.
While the pasta cooks, finely dice the onion, carrot, and celery to create a traditional mirepoix.
Heat the olive oil in a large skillet over medium heat and sauté the onion, carrot, and celery until softened and fragrant, about 5 minutes.
Add the ground beef to the skillet, breaking it up with a wooden spoon, and cook until browned and no longer pink.
Stir in the minced garlic, sea salt, black pepper, and dried oregano, cooking for another minute until the spices are toasted.
Pour in the crushed tomatoes and reduce the heat to low, allowing the sauce to simmer for 10 minutes to develop deep flavors.
Reserve a small splash of pasta water, then drain the pappardelle and add it directly to the skillet with the sauce.
Toss the pasta gently to coat every ribbon, adding a bit of pasta water if needed to reach a glossy consistency.
Serve immediately garnished with chopped fresh basil for a bright, herbal finish.
