Over medium heat, heat olive oil in a frying pan and add the garlic and kale. Add a splash of water and cook until it’s softened and fragrant, about 5 minutes. Remove from the heat.
In a food processor, pulse the kale until it’s chopped into tiny pieces.
Meanwhile, cook noodles according to package instructions until al dente, about 7-9 minutes. Drain and set aside.
In a large pot over medium heat, melt butter with 1 cup evaporated milk.
When butter is melted and mixture is hot and steaming, turn the heat down to low. Add the cooked pasta to the saucepan and stir well.
Add about a quarter of the shredded cheese. Stir until melted and combined. Repeat until all of the cheese is added and noodles are coated with cheese sauce.
Stir in the chopped kale. Add remaining 1/2 cup of evaporated milk to make it creamier.
Add salt and pepper to taste, if desired. Serve warm.
