Mashed Potato Patties with Cheese and Onion

Everyone knows mashed potatoes (well, now you do!) are one of my all-time favorite foods! Have you ever met anyone who doesn't love mashed potatoes? I truly don't think I have. And turning them into cheese and onion mashed potato patties is a delicious way to use leftover mashed potatoes!

My mom would make me a version of these when I was little. So, when she recently suggested I try making them, I was all for it. And I'm so glad she did.

You can't go wrong with traditional mashed potatoes, but turning them into mashed potato patties is a delicious twist on the traditional form. You will not be disappointed!

A lot of people have been regrowing their green onions lately (myself included) so I figured this is another good way to use them up.

The ultimate comfort food in patty form with lots of ooey-gooey cheese, a mix of onions, so much flavor, and it feels like a warm hug for your mouth (if that's a thing?).

Just before everything gets mixed together.

These will become a staple in your kitchen and you'll be looking for any excuse to make them — not that you need one! They're a good recipe to have on hand after holidays, too. I can't think of a better way to use leftover mashed potatoes!

 

Feel free to get creative with what you add to these!

 

Want more cheese? Go for it!

Want to add other veggies or herbs? Give it a shot!

 

Just promise you'll report back to me when you do because I'd love to hear how they turn out!

How to Make Mashed Potato Patties

• Start with cooking white onions and garlic in a large pan with a bit of butter or oil.
• In a large bowl, combine cold mashed potatoes, cheese, green onions, Worcestershire sauce, egg, flour, salt and pepper, and herbs. 

• When the onion and garlic has cooked for 5-7 minutes, add it to the bowl with the mashed potatoes.
• Next, you'll melt more butter or oil in a pan on medium heat. Form the mashed potato "dough" into balls, using about ¼ cup of the mixture for each. Place 3 or 4 in the pan at the time, and gently flatten with your spatula.

• Cook your mashed potato patties on each side for at least 4 minutes, or until nice and golden and crispy. These are still soft-ish when they're done. But the outside gets a bit crispy which I just love! 

Now, time to dig in!

Ingredients Method Notes

Ingredients

  

1x2x3x?

• 2 cups cold mashed potatoes (leftovers, packaged, or pre-made)
• 1 egg
• 1 cup cheddar cheese shredded
• 1 tablespoon Worcestershire sauce*
• ½ large white onion diced
• ¼ cup green onion chopped, plus more for garnish
• 2 garlic cloves minced
• ½ cup flour**
• 2 tablespoon fresh basil*** (optional) chopped
• 2 tbsp fresh parsley*** chopped
• 1 teaspoon salt
• ½ teaspoon black pepper

Method

 

1. In a large bowl, mix all ingredients (EXCEPT white onion, garlic, and butter) until everything is well-incorporated.
2. In a large pan, sautee your white onion and garlic with a bit of olive oil or butter for about five minutes, or until soft and fragrant. Remove from pan and add to the potato mixture.
3. Melt 1 tbsp. of butter in your pan on medium heat.
4. Take about ¼ cup of potato dough (it's sticky!) for each patty, and work into a ball shape.
5. Put 3 or 4 patties into the hot pan, and flatten with a spatula until they're about ½-inch to ¾-inch thick. Then cook on each side for about four minutes until they're golden and beginning to get a bit crispy. Repeat until all of your mashed potato batter is used up.
6. Serve with sour cream and extra green onion (or top with hot sauce or ketchup - the options are endless!) or grab one and eat it cold out of the refrigerator the next day -- they keep really well in the fridge for a few days!

Notes

NOTES:

*I use a generic brand that doesn't have anchovies in it **This amount of flour was perfect for mine, but if your dough seems way too runny, you can try adding a bit more flour ***If using dried parsley and basil, use about half as much
