In a large pot, fill with salted water and set over high heat.

Once the water is boiling add pasta and cook till al dente, following box directions.

While the pasta is cooking start your sauce.

In a large skillet melt butter and olive oil over medium heat.

Add in onions and garlic. Sauté until the onions are translucent and the garlic is fragrant.

Add in tomatoes and capers and sauté until the tomatoes just start to soften. Remove from heat and set aside while your pasta finishes cooking.

Once the pasta is fully cooked, drain and add back to the pot.

Add sauce, Parmesan cheese, olives, and basil to the pasta. Toss to combine and drizzle with more olive oil if the pasta is too dry.

Season with salt and pepper if needed.

Serve warm with a sprinkle of extra grated Parmesan cheese if desired.
