1. Harry Potter and the Lack of Lamb Sauce

Hogwarts fantasy castle

The first Harry Potter crossover fanfiction that we will read today is a very unique crossover. 

This story is a crossover with the television shows Hell’s Kitchen and Master Chef. 

These shows are reality cooking competitions and create a unique Harry Potter crossover. 

This story takes place in Harry’s sixth year at Hogwarts. 

This is the year Professor Snape finally achieves his dream of being the defense against the dark arts teacher, so the position of potions master is available. 

The teacher who comes to fill the position is not at all who any of the students are expecting. 

The new potions master is none other than Gordon Ramsey. 

As you can imagine, this makes for some exciting lessons and a new take on the potions course. 

This story has nearly 700,000 hits and is a very popular Harry Potter crossover fanfiction.

2. Snipers Solve 99% of All Problems

Next up is a Harry Potter crossover fanfiction that incorporates the world of Full Metal Alchemist. 

This story focuses on Ed Elric from Fullmetal Alchemist, but there is still a large amount of Harry Potter content in this story. 

In this story, Ed is thrown into the Wizarding World and forced to reconcile a situation that has arisen. 

He is not happy about dealing with wizards and witches, and he finds them to be a bit nonsensical and loony. 

Nonetheless, he must help them rectify a situation, all while managing to deal with their magic and powers that he does not particularly care for. 

This is a great story that is full of humor and a bit of adult content. 

If you are looking for a story that glorifies the world of Harry Potter, this may not be the one for you, as it calls out many plot holes and mistakes in the series. 

3. On Punching Gods and Absentee Dads

In this Harry Potter crossover fanfiction, we get to enter the Marvel Cinematic Universe world, specifically focusing on Thor. 

This story opens with Harry learning that his father is alive and that he has been hiding since he was a child. 

Instead of being thrilled and excited by this news, Harry is furious and wants revenge on his father. 

Harry sets out to find his father, with his powers growing more robust and uncontrollable daily.

This story is dramatic and angsty, but it also contains a lot of great moments of friendship and love. 

Without giving too much away, this story has a pleasing ending and is not one to miss. 

4. He’s a Killer Queen, Sunflower, Guillotine

Up next is another Harry Potter crossover fanfiction with Fullmetal Alchemist. 

This story takes place at Hogwarts, and a new student has just arrived to shake things up. 

This new student, Edward Elric, is sorted into the Hufflepuff house, where he quickly finds that he does not quite fit in. 

The other Hufflepuffs are wary of him, and he does not exactly go out of his way to make friends or charm anyone. 

There are some original characters in this story and many existing characters that we know and love. 

There are a lot of fun interactions in this story between many different characters.

The author has done a great job of making their interactions feel authentic. 

5. Falling Leaves of Evergreen Trees

The next Harry Potter crossover fanfiction we will read is a crossover with the world of Naruto. 

This story does not have as much magic as many other crossovers, but it is just as captivating and enjoyable to read. 

This story has a lot of world-building and character development, and the author is a talented writer. 

Though many have tried, no one has been able to kill Harry Potter, at least not for long. 

Harry seems to keep returning from the dead, and each time he is more potent and harder to kill. 

This is a fascinating story with a unique plot.

There are currently 65 chapters in this story, with hopefully many more. 

6. Padfoot and Hound

Next up is another Naruto and Harry Potter crossover fanfiction. 

This story differs slightly from the last, primarily focusing on Sirius Black. 

In this story, the ANBU Hound wakes up in England in 1993, where he finds a half-starved dog. 

Sirius wants to find his godson and avoid getting captured, while Kakashi intends to return to his country. 

The two team up to achieve their goals for a unique pairing you won’t find anywhere else. 

This story has a lot of angst and turmoil, but there is also some humor and great storytelling.

7. Yuu and the Power of Magic

In this Harry Potter crossover fanfiction, we experience Twisted Wonderland’s world

This video game plays on many of the elements of Alice in Wonderland but with some interesting new takes. 

In this story, Yuu is a fifth-year student at Hogwarts. 

On the first day of school, she wakes up in an unfamiliar world called Twisted Wonderland, not at Hogwarts. 

Of course, this is jarring and frightening, but Yuu is charmed by this world and its strange charms. 

Nonetheless, Yuu knows she needs to return to the Wizarding World, but this is not as simple as it may seem. 

This lengthy story is still a work in progress, and it follows all of the twists and turns that Yuu faces on her journey back to Hogwarts. 

8. Business

The next Harry Potter crossover fanfiction is a fusion with the world of Sherlock Holmes. 

This short story is only 12,000 words, but it is just as captivating as the others on this list. 

We see a different side to Harry in this story; he is dark, cunning, and incredibly confident. 

He is the opposite of the young, inexperienced boy we know him to be. 

These darker traits can be traced back to the Dursleys and how they raised him. 

Everything Harry did while growing up was wrong.

Meanwhile, everything that Dudley did was right. 

Harry’s upbringing has lasting effects on him and the person he grows up to be. 

This is an exciting and well-written story you may want to read repeatedly.

9. Cupboards and Cryogenics

Up next is another Harry Potter crossover fanfiction with the Marvel Cinematic Universe. 

This story has countless cameos from various Marvel characters but primarily focuses on Captain America and Iron Man. 

This fanfic opens with HYDRA sending The Winter Soldier to retrieve four-year-old Harry Potter. 

The outcome of this mission is not what anyone expected. 

This is an excellent choice if you are looking for an exciting story. 

We get to see many different characters interact with and care for young Harry, and they are delightful to read. 

This story is still a work in progress, so there is plenty of great content for now.

10. Breathe (Don’t Falter)

The final Harry Potter crossover fanfiction that we will read is another crossover with the world of Naruto. 

This story deals heavily with mental health and goes into great detail about some common mental health issues. 

This story is unique because, in this story, Harry is a girl named Jasmine Potter. 

This small change makes a difference, and seeing how it all plays out is fun. 

The author of this story has written a great crossover that flawlessly combines many of the best elements of both Harry Potter and Naruto

It is not necessarily easy, but this author is very skilled.
