Begin by bringing large pot of salted water to a rapid boil.
While waiting for the water to boil, heat a large nonstick pan over medium heat.
Once boiling, cooke the pappardelle pasta until it floats, then drain and set aside. If using boxed pasta, follow box instructions.
Once the pan is heated, add the tomato paste and use a rubber spatula to spread it around.
Toast it until it begins to darken and look dried out. Then, add garlic and onion powder and mix to combine.
Deglaze the pan by adding the rosé wine. Use the rubber spatula to scrape the tomato paste off the bottom of the pan.
Continue to stir over medium heat until the rosé is smooth and has a sort of ketchup-like consistency.
Then, pour in the heavy cream and stir until there are no more clumps of tomato paste.
Add the cooked pasta to the sauce and toss to combine.
Add grated parmesan and cold butter and stir until both are fully incorporated.
Season with salt and pepper to taste, then serve hot and enjoy!
