Boil Noodles: Bring a large pot of water to a boil and cook 10-12 ounces pappardelle pasta to al dente per the package instructions.
Tomato Mixture: Meanwhile, bring a large cast iron skillet to medium-high heat. Add 3-4 tablespoons butter and let melt. Continue to let the butter simmer 3-5 minutes until it starts to brown and the smell becomes almost nutty. Add 2 tablespoons garlic and move around the hot pan until it becomes fragrant, about 30 seconds. Add onion and move around to soften. Season with ½ teaspoon kosher salt and ⅛ teaspoon ground black pepper. Add 1 pint cherry tomatoes and move around the pan until they just start to burst - about 5-10 minutes.
Finish Pasta: Once pasta is done cooking, drain, and add to skillet with butter/tomato mixture. Toss to coat pasta. Taste and season with additional salt or pepper.
Serve: Divide pasta between 2-4 bowls. Add roasted garlic, fresh basil, burrata cheese and shaved parmesan to each bowl. Enjoy!
Notes
Roasted Garlic: the roasted garlic is definitely optional - if you don't feel like taking this extra step don't worry about it, but it does add tons of extra flavor!
