Bring water to a boil in a big pot with some salt & 1 tsp.oil.

Once the water starts to boil, add 3 cups of uncooked pasta into the boiling water.

Let the pasta cook for around 7-8 minutes & check whether the pasta is almost cooked.

Pasta should be almost cooked (al-dente). Rest of the cooking will happen when we mix the pasta with sauce.

Once it is almost cooked, drain the pasta through colander to remove water & add 1 tsp. oil to pasta and mix very well. This avoids pasta from sticking to each other.

Keep the cooked pasta aside & let us start preparing the sauce.

In a saucepan, add 4 tbsp. butter. Make sure the saucepan is in low medium flame.

Once the butter is melted, add 4 tbsp. all purpose flour to it.

Mix them very well, so that there are no lumps.

Keep stirring for around 2-3 minutes, till the raw aroma of uncooked all purpose flour goes off. You have to whisk the mixture continuously to avoid lump formation. It should form a smooth paste.

Add 1/3 milk and continue stirring making sue no lumps are present.

Go on adding 1/3 milk at a time and continue whisking.

Once the entire milk is added & whisked properly, add 120 grams of grated cheese & mix continuously until entire cheese melts & forms a thick sauce.

Add 2 tsp. mixed herbs, 1 tsp. chilli flakes and salt to taste.

Add the cooked pasta into sauce & mix well.

Cook the pasta for 2-3 minutes. Adjust any spices, if required.

Notes - Adjust the spices according to your taste.

Notes - Add more cheese if you prefer more cheesy flavor.

Notes - Serve the pasta immediately, as pasta sauce turns thick & cold and it does not tastes good.

Notes - If having pasta next day, add some milk & cheese to pasta mixture, to make sauce to a thinner consistency.
