Add water to a pot or saucepan and bring it to a boil.
Add salt and add the tagliatelle pasta.
Also add one tablespoon of olive oil, stir well using a good quality spatula and cook in medium heat for about 4 to 6 minutes until the noodles is cooked to your preference. Make sure to stir in between as the pasta is cooked.
Once the noodles is cooked, turn off the heat and carefully drain the water. You may retain a little leftover water (about a cup) in the pot itself which will add a saucy texture once we add the remaining ingredients.
Add the remaining one tablespoon of olive oil and mix well to coat the tagliatelle pasta noodles.
Add the butter, turn on the stove again and saute the noodles in the butter sauce for another 1 to 2 minutes.
Also add the seasonings like parsley, black pepper, garlic and onion powders.Add the shredded cheese too and mix in with the pasta. Turn of the heat and transfer the prepared, buttered tagliatelle pasta to serving plates.
Top with red chili flakes (optional), and more parsley flakes.
Also add the tomato garlic sauce (or any sauce of your preference, alfredo sauce is another great choice!). Serve hot & enjoy!
Alternatively, you can toss the noodles in pasta sauce in a large skillet or pan, add little more olive oil (about ¼ cup) and stir fry the noodles in sauce for about 1 to 2 minutes for the best flavors!
