Preheat your oven to 400°F.
On a sheet tray place the tomatoes. Drizzle with olive oil and a sprinkling of salt and pepper. Once the oven is up to temperature, roast the tomatoes for 15 minutes or until nicely charred and almost bursting.
Meanwhile, bring a large stock pot of salted water up to a boil. Cook the pasta per package directions until al dente. Save 1½ cups of the cooking liquid before you drain the pasta. Drain pasta and set aside.
In the same pot you cooked the pasta in, add the butter and pepper and cook until melted. Next add in 1 cup of the pasta water, pasta and grated Parmesan cheese. Cook until the sauce is thickened and creamy, adding more pasta water if it gets too thick. Taste for seasoning, adding salt if needed.
Serve immediately with the roasted tomatoes on the side.
