Delicious Broccoli Cheddar Mashed Potato Cakes

Meta Description: Learn how to turn leftover mashed potatoes into crispy, cheesy broccoli cheddar cakes. This easy recipe is a perfect way to reinvent a classic side dish into a delicious new meal.

My family has a serious love for mashed potatoes. They’re a classic for a reason—creamy, comforting, and an essential part of almost every holiday meal. But no matter how hard we try, there are always leftovers. And for years, those leftovers would just sit in the fridge, waiting for a purpose they never found. I was determined to stop the food waste and turn the humble leftover mashed potato into something exciting and new. I wanted a dish that felt just as comforting but had a different texture, something with a satisfying crunch.

My solution was these broccoli cheddar mashed potato cakes. They are everything a great leftover recipe should be: simple, delicious, and a total crowd-pleaser. We’re taking the classic, cheesy broccoli and potato combo and turning it into a crispy, golden-brown patty. The cakes are tender on the inside, with a beautiful crust on the outside, and they’re perfect for a quick lunch, a light dinner, or a fun side dish. This recipe has completely changed the way I think about leftovers, and I have a feeling it will change yours, too.

🌟 The Magic of Leftover Mashed Potatoes

The secret to these delicious potato cakes is that they start with cold, leftover mashed potatoes. This is key because cold potatoes are firmer and hold their shape better when you form them into patties. Trying to make potato cakes with fresh, warm mashed potatoes would be a soggy, frustrating mess. So, next time you have a bowl of leftover mashed potatoes in your fridge, don’t throw it out! It’s the perfect ingredient for a delicious new meal.

We’re also adding a few other simple ingredients to the mix. The broccoli cheddar potato cakes get their incredible flavor from a blend of sharp cheddar cheese and finely chopped broccoli florets. The cheddar provides a savory, nutty richness that melts into the potatoes, while the broccoli adds a nice bit of texture and a pop of freshness. A little bit of flour and an egg help to bind everything together, ensuring that the cakes stay in one piece when you pan-fry them. The result is a simple, rustic, and incredibly satisfying dish that feels both new and familiar.

✅ Ingredients You’ll Need

This recipe uses a handful of simple, accessible ingredients that you likely have in your kitchen right now, especially after a big meal.

For the Potato Cakes:

• 3 cups cold leftover mashed potatoes
• 1 cup shredded sharp cheddar cheese
• 1 cup finely chopped broccoli florets, blanched or steamed
• 1 large egg, lightly beaten
• 1/4 cup all-purpose flour
• 2 tablespoons chopped fresh chives (optional)
• 1/2 teaspoon kosher salt
• 1/4 teaspoon black pepper
• 2 tablespoons vegetable oil or butter for frying

For Serving (Optional):

• Sour cream
• Extra chives for garnish

📝 Step-by-Step Instructions

Total Preparation and Cooking Time: 25 minutes

1. Prep the Broccoli: If you’re using fresh broccoli, you’ll need to blanch it first. Bring a small pot of salted water to a boil. Add the broccoli florets and cook for 1-2 minutes until they are bright green and tender-crisp. Immediately drain the broccoli and transfer it to an ice bath to stop the cooking process. Drain again and pat dry before finely chopping. If you’re using leftover cooked broccoli, just make sure it’s chopped and dry.
2. Combine the Ingredients: In a large bowl, combine the cold mashed potatoes, shredded cheddar cheese, finely chopped broccoli, lightly beaten egg, all-purpose flour, chives (if using), salt, and pepper. Use your hands or a large spoon to mix everything together until it’s just combined. Don’t overmix!
3. Form the Cakes: Scoop about a quarter-cup of the mixture at a time and gently form it into a patty, about 1-inch thick. The mixture will be a little sticky, but that’s okay. Place the patties on a plate or a baking sheet.
4. Cook the Cakes: Heat the vegetable oil or butter in a large non-stick skillet over medium-high heat. Carefully place the potato cakes in the hot skillet, making sure not to overcrowd the pan. Cook for about 4-5 minutes per side, until they are golden brown and have a nice crispy crust. The inside will be heated through and tender.
5. Serve and Garnish: Once the cakes are cooked, carefully transfer them to a plate. Serve the cheesy mashed potato cakes immediately with a dollop of sour cream and a sprinkle of fresh chives on top. Enjoy your delicious and easy meal!

😋 Creative Variations and Serving Suggestions

This easy potato cake recipe is a fantastic base for all sorts of delicious creations. You can easily adapt it to fit your taste or to use up ingredients you have on hand.

• Add a Protein: To make this a heartier meal, you can add some cooked, crumbled bacon or diced ham to the mixture before you form the patties. This would make them a more substantial dinner.
• Try Different Cheeses: While cheddar is a classic choice, a mix of Gruyère and Swiss would be fantastic. You could also use a little bit of Monterey Jack for a milder, meltier finish.
• Try a Different Vegetable: You can easily swap out the broccoli for other vegetables. Cooked corn kernels, sautéed mushrooms, or even some grated carrots would all be delicious additions. Just make sure to cook and drain them first!
• Make them Gluten-Free: To make these potato cakes gluten-free, simply swap the all-purpose flour for a gluten-free all-purpose flour blend. You can also use almond flour or a gluten-free breadcrumb as a binder.
• Serving Ideas: These potato cakes are a great side dish for a variety of meals, but they are also a perfect light lunch or dinner. They pair wonderfully with a simple green salad, grilled chicken, or a side of sausage. A little extra shredded cheddar cheese on top would also be a great idea.

❓ Frequently Asked Questions (FAQ)

Can I use fresh mashed potatoes?

For this recipe, it’s best to use cold, leftover mashed potatoes. Fresh, warm mashed potatoes are too soft and will likely fall apart when you try to form them into patties. The cold potatoes help the starch molecules firm up and hold their shape better.

How do I store and reheat leftovers?

Leftover potato cakes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, you can pop them in a toaster oven, a preheated oven, or an air fryer to get them crispy again. The microwave will work, but it may make the cakes a little soft and lose their crunch.

Why are my cakes falling apart?

Cakes that fall apart are usually the result of not having enough of a binder, or using mashed potatoes that are too thin. The egg and flour are crucial here. If your mashed potatoes were a little on the thin side to begin with, you can add a little extra flour to the mixture to help them hold their shape.
