I want to tell you about the my lovely recipe.

For this meal Iyou need pasta, mushrooms, chicken, an onion, salt, peper, cream.

It's the my personal recipe, although it looks like thea classic Italian pasta.

The classic Italian pasta implies there is only one classic Italian pasta. Use “a” an indefinite article

First of all, I chop the chiken, the onion and mushrooms.

Then, I turn on a platthe stove and put on a pan.

You can turn on a stove or a hot plate

After that, I put on some olive oil withand fry the onion on the pan.

After 5 minutes, add chiken and mushrooms and friedy for about 15 minutes.

Fried is the past tense. Fry is present tense

Then, I put on the platstove a pot with water.

Add pasta in the pot when water hads boiled.

Cook the pastea for 5 or 7 minutes.

Finnaly Ially, add the pasta to the pan and mix it.

I want to tellalk about the my lovely recipe.

It's either "tell you" or "talk"; you cannot use "tell" by itself.

It's a recipe for pasta with chicken and mushrooms.

The recipe isn't the pasta, it's a *recipe for* the pasta.

For this meal I need pasta, mushrooms, chicken, anone onion, salt, pepper, and cream.

If you're telling us about the recipe, it's more natural to use "you." "You" here wouldn't be used as the regular 2nd person pronoun; it refers to people in general, much like the more formal "one."

Because this is a recipe, "one onion" is better than "an onion" (although both are correct).
You need "and" before the last item in a list.

ItThis isn't the classic pasta.

It's the my personal recipe, which looks like the classic Italian pasta.

You don't use articles before "my."

First of all, I chop the chicken, the onion, and the mushrooms.

You can also say "the chicken, onion, and mushrooms" because when you have a list, you can omit the "the" in subsequent items. However, if you choose to put "the" for "the onions," you also need to put it in front of "mushrooms."

Then, I turn on a platlight up the stove and put on a pan.

I'm assuming this is what you meant.

After that, I put on some olive oil withand the onion on the pan.

After 5 minutes, add the chicken and mushrooms and friedy for about 15 minutes.

Then, I put on the plate a pot with watera pot of water on the stove.

"I put on the stove a pot of water" is also fine, but rather formal.

AI add pasta into the pot when the water hadstarts boileding.

It should be "water has boiled," not "water had boiled"; however, both are kind of weird here.
"when the water comes to a boil" also works.

Cook the pastea for 5 tor 7 minutes.

5 or 7 = 5 minutes/7 minutes
5 to 7 = between 5 and 7 minutes

Finnally, I add the pasta to the pan and mix it.
