Mashed Potato Muffins

Honestly, leftover mashed potatoes are one of those things I never want to throw away, but eating the same bowl of potatoes two days in a row can get a little boring. That’s why I love making these mashed potato muffins! They turn simple leftover mashed potatoes into something completely different, with golden, crispy edges, a soft and fluffy center, and plenty of melted cheddar cheese.

The first time I made these, I was just looking for a quick way to use up the mashed potatoes sitting in my refrigerator. I pressed the mixture into a muffin tin, added some extra cheese, and popped everything into the oven. The result? Little savory potato muffins that looked beautiful, smelled amazing, and disappeared from the kitchen surprisingly fast!

What I especially love about this recipe is how simple it is. You only need three main ingredients, and you probably already have them in your kitchen. There’s no complicated preparation, no fancy equipment, and very little cleanup.

These cheesy mashed potato muffins are perfect for breakfast, brunch, holiday dinners, weeknight meals, or even an afternoon snack. I usually make a batch whenever I have leftover mashed potatoes, and sometimes I find myself making mashed potatoes specifically for this recipe!

If you love crispy potato edges and gooey cheddar cheese, this easy recipe is definitely worth saving.

Why You’ll Love These Mashed Potato Muffins

• Only 3 main ingredients: Leftover mashed potatoes, one egg, and shredded cheddar cheese are all you need.
• Crispy on the outside: Baking the potatoes in a muffin tin creates delicious golden edges.
• Soft and cheesy inside: The centers stay tender while the cheese melts into the potatoes.
• Perfect for leftovers: Give yesterday’s mashed potatoes a fresh, delicious makeover.
• Easy to customize: Add herbs, garlic powder, cooked bacon, or your favorite seasonings.
• Great for meal prep: Make them ahead and reheat them for a quick side dish or snack.

Ingredients for Mashed Potato Muffins

This recipe makes approximately 12 standard-size muffins, depending on the size of your muffin tin and how generously you fill each cup.

Ingredients

• 3 cups leftover mashed potatoes: Cold mashed potatoes work well because they’re easy to scoop and shape. Plain or lightly seasoned potatoes are ideal.
• 1 large egg: Helps bind the mixture together so the muffins hold their shape after baking.
• 1 cup shredded cheddar cheese, divided: Adds a rich, cheesy flavor and creates a delicious golden topping.

Optional Ingredients for Extra Flavor

The basic recipe is wonderfully simple, but I sometimes add a little extra seasoning when I want to change things up.

• 2 tablespoons chopped fresh chives or green onions
• ¼ teaspoon garlic powder
• ¼ teaspoon black pepper
• 1 tablespoon chopped fresh parsley
• A pinch of smoked paprika
• Cooking spray or a little butter for greasing the muffin tin

A quick note about the potatoes: If your leftover mashed potatoes already contain butter, milk, cream, or seasoning, that’s perfectly fine. Just remember that very loose or watery mashed potatoes may need a little extra care to help the muffins hold their shape.

How to Make Mashed Potato Muffins

These cheesy potato muffins are easy enough for beginner cooks. The key is mixing everything well, greasing your muffin tin, and giving the tops enough time to become beautifully golden.

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C).

Lightly grease a standard 12-cup muffin tin with cooking spray or butter. I recommend greasing the sides and bottoms thoroughly because mashed potatoes and melted cheese can stick, especially around the crispy edges.

If your muffin tin tends to stick, don’t skip this step!

Step 2: Prepare the Potato Mixture

Add the 3 cups of leftover mashed potatoes to a large mixing bowl.

Stir in the large egg and mix until everything is evenly combined. Add about ¾ cup of the shredded cheddar cheese, reserving the remaining ¼ cup for the tops.

If you’re using garlic powder, black pepper, chives, or other seasonings, mix them in now.

I usually start with the basic ingredients and taste a tiny bit of the potato mixture before adding extra salt. Leftover mashed potatoes are often already seasoned, and cheddar cheese adds plenty of flavor on its own.

The mixture should be thick enough to scoop into the muffin tin. If your potatoes are unusually soft, avoid adding extra liquid.

Step 3: Fill the Muffin Tin

Divide the mashed potato mixture evenly among the prepared muffin cups.

Fill each cup nearly to the top, then gently press the mixture down with the back of a spoon. You can smooth the tops or leave them slightly uneven for more crispy edges.

Sprinkle the remaining ¼ cup of cheddar cheese over the muffins.

For extra texture, I like to leave a few small ridges on top instead of smoothing everything completely flat. Those little edges can turn deliciously golden as they bake.

Step 4: Bake Until Golden

Place the muffin tin in the preheated oven and bake for approximately 25–35 minutes, or until the tops are golden brown and the edges look crisp.

Oven temperatures and mashed potato consistency can vary, so start checking around the 25-minute mark.

If the muffins look pale, give them a few extra minutes. You’re looking for lightly browned edges, melted cheese, and centers that feel set rather than wet.

For an extra-crispy finish, you can broil them briefly at the end, watching carefully to prevent the cheese from burning.

Step 5: Let Them Rest

Remove the muffin tin from the oven and let the potato muffins rest for about 5–10 minutes.

This is an important step! The muffins will be delicate while they’re piping hot, but they firm up as they cool slightly.

Run a thin silicone spatula or butter knife carefully around the edges if needed, then lift each muffin out of the tin.

Serve warm and enjoy those crispy edges and cheesy centers.

Tips for Perfect Mashed Potato Muffins

A few small details can make a big difference in how your potato muffins turn out.

1. Start With Thick Mashed Potatoes

The consistency of your mashed potatoes matters. Thick, creamy potatoes generally produce muffins that hold together better than very loose mashed potatoes.

If your mixture seems too soft to scoop, chill it for 20–30 minutes before filling the muffin tin.

2. Use Freshly Shredded Cheese

I usually prefer shredding cheddar from a block because it melts nicely and gives the muffins a delicious cheesy texture. Pre-shredded cheese also works if that’s what you have on hand.

Sharp cheddar is especially good because it adds a stronger flavor without needing lots of extra ingredients.

3. Grease the Muffin Tin Generously

Potatoes and cheese can stick to the pan, especially after the cheese browns. Greasing each cup well makes removing the muffins much easier.

A good-quality nonstick muffin tin also helps.

4. Don’t Remove Them Too Soon

It’s tempting to pull the muffins out immediately, but giving them a few minutes to rest helps them set. If you try to remove them while they’re extremely hot, they may break apart.

5. Don’t Overmix

Mix just until the egg, potatoes, and cheese are combined. You want an even mixture without unnecessarily working the potatoes.

6. Make Them Your Own

This recipe is easy to customize. Try adding cooked, crumbled bacon, diced ham, sautéed onions, chopped broccoli, or fresh herbs.

Just be careful with watery vegetables, as too much moisture can make the muffins softer.

7. Check Your Muffin Tin Size

Smaller muffin cups will cook faster, while larger cups may need extra baking time. Keep an eye on the tops and edges rather than relying on the timer alone.

What to Serve With Mashed Potato Muffins

One of my favorite things about this recipe is how many different ways you can serve it. These little potato muffins fit right into almost any meal.

For Breakfast or Brunch

Serve them with scrambled eggs, fried eggs, turkey sausage, fresh fruit, or sautéed vegetables. They’re a fun alternative to hash browns and make a hearty addition to a weekend brunch spread.

With Dinner

These muffins are a natural match for roasted chicken, grilled steak, baked fish, meatloaf, or pork chops. Add a green salad or roasted vegetables for a complete meal.

For Holidays and Family Gatherings

Instead of serving mashed potatoes in a large bowl, offer individual potato muffins at Thanksgiving, Christmas, Easter, or Sunday dinner. They’re easy to portion and look lovely on a serving platter.

As a Snack or Appetizer

Serve them warm with sour cream, Greek yogurt, ranch dressing, or a sprinkle of chopped chives.

For a party, you can make them in a mini muffin tin for bite-sized portions. Just reduce the baking time and check them frequently.

Variations to Try

Once you’ve made the original version, it’s easy to experiment with different flavors.

Bacon Cheddar Potato Muffins: Stir in cooked, crumbled bacon for a smoky, savory twist.

Garlic Herb Potato Muffins: Add garlic powder, parsley, chives, and a little black pepper.

Broccoli Cheddar Potato Muffins: Fold in finely chopped, cooked broccoli for extra color and flavor. Make sure it’s well drained.

Spicy Potato Muffins: Add a pinch of cayenne pepper or finely diced jalapeños.

Parmesan Potato Muffins: Replace some of the cheddar with grated Parmesan for a sharper, saltier flavor.

Loaded Baked Potato Muffins: Add bacon, green onions, cheddar, and a little sour cream on the side for serving.

Storage, Freezing, and Reheating

These mashed potato muffins are great for making ahead, especially if you want an easy side dish ready for busy days.

How to Store Leftovers

Let the muffins cool, then place them in an airtight container and refrigerate within two hours of cooking. Store them in the refrigerator for up to 3–4 days.

Can You Freeze Mashed Potato Muffins?

Yes! Allow the muffins to cool completely, then arrange them in a single layer and freeze until firm. Transfer them to a freezer-safe container or bag, separating layers with parchment paper if necessary.

For best quality, use within 2–3 months.

Thaw them in the refrigerator before reheating, or reheat directly from frozen until hot throughout.

How to Reheat Them

• Oven: Heat at 350°F (175°C) for about 10–15 minutes, or until warmed through.
• Air fryer: Reheat at 350°F (175°C) for approximately 4–7 minutes, checking frequently.
• Microwave: Heat in short intervals until warm. The texture will be softer and less crispy.

Honestly, I prefer the oven or air fryer because the edges become crisp again instead of turning soft.

Frequently Asked Questions

1. Why are my mashed potato muffins falling apart?

This usually happens when the potato mixture is too loose or the muffins haven’t had enough time to set. Make sure you use the egg, avoid adding excess liquid, and let the muffins rest for 5–10 minutes after baking. Chilling a very soft mixture before baking can also help.

2. Can I make mashed potato muffins without eggs?

Yes, although the texture may be more delicate because the egg helps bind the ingredients together. You can experiment with a commercial egg replacer, but the results may vary. Be sure to grease the pan well and allow the muffins to cool before removing them.

3. Can I use instant mashed potatoes?

Yes. Prepare the instant potatoes according to the package instructions, but keep them fairly thick rather than adding extra milk or water. Let them cool before mixing in the egg and cheese.

Since the moisture level can differ from homemade mashed potatoes, you may need to adjust the consistency slightly.

4. Can I make these mashed potato muffins ahead of time?

Absolutely! You can bake them a day or two ahead and refrigerate them in an airtight container. Reheat them in the oven or air fryer before serving to bring back some of their crispiness.

You can also prepare the potato mixture ahead of time, keep it refrigerated, and bake it later. For food safety, refrigerate promptly and bake the mixture within 1–2 days.

5. How do I get extra-crispy mashed potato muffins?

Start with thick mashed potatoes, grease the muffin tin well, and bake at 400°F (200°C) until the edges are golden brown. Avoid overcrowding the muffin cups, and allow the muffins to rest before removing them.

For an extra-crispy finish, a few minutes in the air fryer can work wonders.
