Bring your favorite magical book series to life with this incredible Harry Potter bangers and mash recipe! It's inspired by a meal at Hogwarts in the Great Hall. Fluffy mashed potatoes are topped with savory onion gravy, served with your favorite spicy, mild, or meatless sausage.

Traditional British Bangers and Mash

The word "bangers" does not just apply to a really dance-able song. It also refers to sausages. But not just any old sausage, my friends. "Bangers" is an old a term used to describe the sausages during World War I that would be packed with cheap fillers like water. Because they were so waterlogged, they would bang, pop and explode while being cooked! Hence, bangers.

Traditional bangers or sausages are made from veal, pork, or beef. For ease, I reach for store-bought sausages instead. But if you're feeling adventurous, go ahead and make your own bangers at home! Just don't fill them with water like they did in the 20th century. No one wants exploded sausage on their ceiling...

My Grandma was British, and while I'm not certain if she ever made bangers and mash herself, my Dad makes the best mashed potatoes in the world. He adds a dash of nutmeg, which most people would never think to add. And of course, a generous amount of butter and half-and-half never hurt.

A Hearty Dinner, Inspired by Harry Potter

Harry Potter ate bangers and mash for dinner before the very first meeting with Dumbledore's Army in book five, Harry Potter and the Order of the Phoenix. Did I feel like I was about to sneak under Umbridge's nose to learn the Patronus charm in the room of requirement after eating Harry Potter Bangers and Mash? Yes, yes I did.

And in case you hadn't noticed, I am a bit of a Harry Potter fan. Have I read all the books more than thrice? Do I have a permanent Harry Potter-themed tattoo? Do I have even more Harry Potter recipes from this magical series to share with you? Yes, yes, and of course, yes. Stay magical, and don't let the muggles get you down!

Ingredients
  

Bangers (Sausages)

  • 6 sausages (mild, spicy, or meatless)

Mash (Mashed Potatoes)

  • 6 medium Yukon Gold or Russet potatoes
  • 2 teaspoons salt
  • 4 Tablespoons unsalted butter (½ stick)
  • 1 cup whole milk (or half-and-half)
  • ½ teaspoon ground black pepper
  • ¼ teaspoon ground nutmeg

Onion Gravy

  • 3 Tablespoons olive oil
  • 1 medium yellow onion, finely diced
  • 3 Tablespoons all-purpose flour
  • 2 cups low-sodium vegetable broth
  • salt, to taste, depending on the saltiness of your broth

Instructions
 

Mashed Potatoes

  • Peel and quarter the potatoes. Place them in a pot and fill it with water to cover the potatoes by about an inch of water. Bring the pot to a boil on high heat, then reduce the heat to medium-low and simmer for about 25 minutes, or until a fork easily pierces the potatoes.
  • Drain the potatoes into a colander. Add the potatoes back into the pot along with the salt, butter, milk, black pepper and nutmeg. Mash the potatoes with a potato masher or a large fork just until they are light and fluffy, being careful not to overmix.

Onion Gravy

  • Heat the oil in a saucepan on medium-low heat and add the diced onion. Cook until the onions are golden and caramelized, after about 20-30 minutes.
  • Add the flour to the saucepan and whisk until everything becomes smooth.
  • Increase the heat to medium and add the broth. Whisk constantly until it forms a thick and bubbling gravy. Take a taste test and add more salt if needed.

Bangers and Mash

  • To serve, place a few large dollops of your mashed potatoes on a plate. Add one or two sausages and a hearty serving of onion gravy over everything. Enjoy!

Notes

  • Don't over-mix the potatoes once they come together, which can cause the starch in the potatoes to create a gluey, gross mess.

    🤤 I love Harry Potter! I've been wanting to read the books with my son but he isn't interested at all! He is all sports stuff so I guess I will be rereading the books in my own. Congrats on your engagement and have a blast on your honeymoon! Please let me know how the trip goes. I want to make a trip there as well!

      I wonder if he would get into the books of you first read him a passage about qudditch since that's fairly sports-related? I finally got my fiancé into Harry Potter so now I can make all the inside jokes to him 😂 I hope you get to make a trip to Harry Potter world soon - I'll let you know how mine goes and pass on any tips and tricks!! 🥰
