It's quite possibly the cheesiest day of the year.

Not too mention the meatiest.

It's National Cheesesteak Day and we're all about it here at PennLive. Keep on reading and you'll see how to make the perfect Philadelphia cheesesteak, where you can nab a free one and where to get a delicious one in the Harrisburg-area.

We'll even share with you where the best cheesesteak in the state is (and it pains this Philadelphia-based reporter to share that it isn't in Philly).

But first, the history of the cheesesteak (because you ought to be an informed cheesesteak eater).

VisitPhilly puts its origin in the 1930s, when Pat Olivieri put some beef on his grill and made a steak sandwich for a taxi driver. The driver liked it, word spread and Pat's King of Steaks became a thing. So where does the infamous Geno's, Pat's rivalry come in? Well, both claim to have put cheese on the steak sandwich first.

You can make your own cheesesteak by following the instructions in the video below.

Not sure what kind of cheese, meat or bread to get for your cheesesteak? Let us break it down for you.

What's better than a cheesesteak? A free one.

But you'll have to travel to New Jersey for it.

Tony Luke Jr. (of Tony Luke's fame) will be giving out free cheesesteaks at the chain's Sicklerville, New Jersey store from noon-6 p.m. (or until they run out). Can't make it to the Sicklerville locale? A portion of the day's proceeds from all of the Tony Luke's locations will be donated to the HollyRod Foundation to help autism awareness.

For the die-hard Geno's Steaks fans, the restaurant is giving away Geno gear in a Twitter scavenger hunt all day. Simply follow @GenosSteaks to get a clue for a location where you can go to score a bag of Geno's swag. You can also follow #CheesesteakChase17.

The important thing on National Cheesesteak Day is to not settle for anything less than delicious. With that in mind, here's a list of the best cheesesteaks in the state. And, spoiler alert, the number one spot goes to a shop in Pittsburgh.

If you're in central Pennsylvania, you can still nab a delicious cheesesteak. There's lots of great options, including Shugar's Deli in New Cumberland and The Jackson House in Harrisburg.

And if you really can't live without a Philly cheesesteak from Philadelphia and are nowhere near, you can always order one online. Both Jim's and Campo's will ship a cheesesteak anywhere in the United States -- but for a hefty prize. A four-pack of cheesesteaks from Jim's is $99 from goldbely.com; while a package with two Campo's cheesesteaks, soft pretzels, Tastycakes, peanut chews and Herr's chips is $74.95 from foodydirect.com.
