Ingredients You’ll Need
The magic behind this Cheesy Mashed Potato Patties Recipe lies in a handful of simple, everyday ingredients that come together to create the perfect balance of flavor and texture. Each item has a role, from the creamy mashed potatoes that form the base to the sharp cheddar cheese that adds a melty richness.
- 2 cups cold leftover mashed potatoes: Using cold potatoes helps the patties hold their shape better while frying.
- 1/2 cup shredded cheddar cheese: Adds melty goodness and a sharp, tangy flavor that complements the potatoes perfectly.
- 1/4 cup chopped green onions: Brings a fresh, slightly pungent bite and a pop of color.
- 1/4 cup all-purpose flour: Helps bind the mixture together for firm patties that don’t fall apart.
- 1 large egg: Another binding agent that ensures a smooth, cohesive texture.
- Salt and pepper to taste: Enhances all the flavors and adds just the right seasoning.
- 2 tablespoons vegetable oil: Used for frying to create that crispy, golden crust everyone loves.
How to Make Cheesy Mashed Potato Patties Recipe
Step 1: Mix the Ingredients
Start by placing your cold leftover mashed potatoes in a large bowl. Add in the shredded cheddar cheese, chopped green onions, all-purpose flour, egg, salt, and pepper. Use a spoon or your hands to mix everything thoroughly until the mixture comes together and holds well. This step is key because you want the patties to stay intact during cooking.
Step 2: Form the Patties
Once your mixture is well combined, scoop out about 2 tablespoons at a time and shape them into small, even patties. Aim for consistency in size so they cook evenly. If the mixture feels too sticky or loose, refrigerate it for 10-15 minutes to firm up.
Step 3: Heat the Oil and Fry
Heat the vegetable oil in a large skillet over medium heat until shimmering. Carefully add the patties in batches, making sure not to overcrowd the pan. Fry each side for about 3 to 4 minutes until they turn golden brown and develop a beautiful crispy crust. Adjust the heat as necessary to avoid burning. Use a slotted spatula to transfer them to paper towels to drain any excess oil.
How to Serve Cheesy Mashed Potato Patties Recipe

Garnishes
Sprinkle your hot patties with freshly chopped herbs like parsley or chives for an added layer of freshness and vibrant green color. A dollop of sour cream or a drizzle of spicy aioli complements the cheesy interior superbly, giving every bite a creamy kick.
Side Dishes
While these patties can hold the spotlight on their own, pairing them with a crisp green salad or tangy coleslaw cuts through the richness nicely. For a heartier meal, serve alongside grilled meats or a comforting bowl of soup for contrast and balance.
Creative Ways to Present
Turn these patties into sliders by sandwiching them between mini buns with lettuce, tomato, and your favorite sauce. Alternatively, top each patty with a spoonful of salsa or guacamole for a fun twist. You could even assemble a breakfast plate by adding a fried egg on top for a decadent morning treat.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, cool them completely before storing in an airtight container. They’ll keep well in the refrigerator for up to 3 days, making for a quick snack or side anytime you want a cheesy potato fix.
Freezing
To freeze, lay the patties out on a baking sheet lined with parchment paper and freeze until solid. Then transfer them to a freezer-safe bag or container. Frozen patties can last up to 2 months and are perfect to keep on hand for last-minute meals or snacks.
Reheating
For reheating, the best way to restore their crispiness is to pop them in a hot skillet with a little oil for a few minutes per side. You can also use your oven or toaster oven at 375°F (190°C) for about 10 minutes. Avoid microwaving if you want to keep that delightful crunch.
FAQs
Can I use fresh mashed potatoes instead of leftovers?
Absolutely! Just make sure the mashed potatoes are well chilled and not too watery. You can refrigerate freshly made mash before making the patties to help them firm up.
What other cheeses can I use?
Feel free to try different cheeses like mozzarella for a gooey stretch or pepper jack to add some heat. Mixing cheeses can also create interesting flavors and textures.
Can I bake the patties instead of frying?
Yes, baking is an option for a lighter version. Place patties on a parchment-lined baking sheet, spray lightly with oil, and bake at 425°F (220°C) for 15-20 minutes, flipping halfway through for even browning.
How do I make these gluten-free?
Just swap the all-purpose flour for a gluten-free alternative like rice flour or almond flour. The patties will still hold together nicely with these substitutions.
Can I add other mix-ins to the patties?
Definitely! Cooked bacon bits, sautéed mushrooms, or finely chopped herbs all make wonderful additions. Just be careful not to add too much moisture, which can make shaping the patties tricky.
