Ingredients for Perfect Mashed Potato Muffins

Here’s everything you’ll need for this simple, delicious recipe.

The Core Ingredients:

· 3 cups leftover mashed potatoes — See Kelly’s Notes below for important tips!
· 1 large egg — Acts as a binder, holding the muffins together .
· 1 cup shredded cheddar cheese, divided — Sharp cheddar adds the most flavor, but any good melting cheese works .
· 3 tablespoons chopped fresh chives, divided — For color, freshness, and mild onion flavor .

Optional Add-Ins and Toppings:

· 4 slices bacon, cooked and crumbled — Because bacon makes everything better .
· ¼ cup sour cream or Greek yogurt — Adds tanginess and moisture .
· 2 green onions, sliced — Extra onion flavor and color .
· ¼ cup grated Parmesan cheese — For sprinkling on top before baking .
· Paprika or smoked paprika — For sprinkling on top and extra color .
· Salt and pepper to taste — Depending on how seasoned your potatoes already are .

Kelly’s Notes on Leftover Mashed Potatoes:

The type of leftover mashed potatoes you use makes a difference. Here’s what to keep in mind:

· Temperature: Cold, leftover mashed potatoes work best. They’re firmer and easier to mix than warm potatoes .
· Consistency: If your potatoes are very thin and runny (too much milk/cream), the muffins may be dense. If they’re thick and stiff, they’ll work perfectly .
· Seasoning: Factor in how seasoned your potatoes already are. If they’re heavily salted and buttered, you may need less added salt . Taste your potato mixture before adding more salt.
· Lumps are fine: Slightly lumpy mashed potatoes add texture and character to these muffins .
· Make fresh if needed: Don’t have leftovers? You can make a fresh batch of mashed potatoes specifically for this recipe. Just make sure they’re cooled slightly before mixing .

Step-by-Step Instructions

Follow these simple steps for perfect mashed potato muffins every time.

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C) . Generously grease a 12-cup muffin tin with butter, oil, or non-stick cooking spray. You can also use muffin liners, but greasing the pan gives those crispy edges that are so delicious .

Step 2: Mix the Base

In a large bowl, combine the cold leftover mashed potatoes and 1 large egg. Mix well until the egg is fully incorporated and the mixture is smooth . The egg acts as a binder, helping the muffins hold their shape.

Step 3: Add Cheese and Chives

Reserve about ¼ cup of the shredded cheddar cheese and 1 tablespoon of the chopped chives for topping. Add the remaining ¾ cup cheddar cheese and 2 tablespoons chives to the potato mixture. If you’re using any optional add-ins like bacon or sour cream, add them now .

Step 4: Season to Taste

Taste the mixture and adjust seasoning with salt and pepper if needed. Remember that your potatoes may already be well-seasoned, so go easy .

Step 5: Fill the Muffin Tin

Scoop the potato mixture evenly into the prepared muffin cups, filling them to the top. The mixture won’t rise much, so you can fill them generously . Use a spoon or small cookie scoop for even portions.

Step 6: Add Toppings

Sprinkle the reserved ¼ cup cheddar cheese over the tops of each muffin. Add the remaining 1 tablespoon chives. If using Parmesan or paprika, sprinkle those on now .

Step 7: Bake

Bake for 20-25 minutes, or until the muffins are golden brown on top and slightly firm to the touch. A toothpick inserted in the center should come out clean (though cheesy goodness may stick) .

Step 8: Cool and Serve

Let the muffins cool in the pan for 5-10 minutes before carefully removing them with a fork or small spatula . This resting time allows them to set and makes removal easier. Serve warm.

Pro Tips for the Best Mashed Potato Muffins

1. Use Cold Potatoes

Cold, leftover mashed potatoes are ideal. They’re firmer and easier to work with than warm potatoes, and they help the muffins hold their shape better during mixing and baking .

2. Don’t Overmix

Mix just until ingredients are combined. Overmixing can make the muffins dense and gummy instead of light and fluffy .

3. Grease the Pan Well

These muffins love to stick! Generously grease every nook and cranny of your muffin tin, or use silicone muffin liners for guaranteed easy release . The crispy edges that form where the muffin meets the pan are part of the magic.

4. Customize Your Cheese

While sharp cheddar is classic, feel free to experiment. Gruyère adds nutty elegance, pepper jack brings heat, and a mix of mozzarella and Parmesan creates a delightful stretchy-top situation .

5. Add Mix-Ins Thoughtfully

If your mashed potatoes are on the looser side, be cautious with add-ins that add more moisture (like sour cream). If they’re thick and stiff, you have more flexibility .

6. Make Them Mini

For appetizers or party snacks, use a mini muffin tin and reduce baking time to 12-15 minutes. Perfect for bite-sized entertaining !

7. Double the Batch

These muffins freeze beautifully, so consider making a double batch. They’re so handy to have on hand for quick breakfasts or side dishes.

Delicious Variations to Try

1. Loaded Baked Potato Muffins

Add ¼ cup sour cream to the mixture, fold in crumbled bacon and extra cheddar, and top with more bacon and chives before baking. Serve with an extra dollop of sour cream .

2. Garlic Parmesan Mashed Potato Muffins

Add 2 cloves minced garlic (roasted for extra sweetness) to the mixture. Use Parmesan cheese instead of cheddar, both in the muffins and on top. Sprinkle with Italian seasoning before baking .

3. Jalapeño Popper Muffins

Add ¼ cup diced pickled jalapeños, 4 oz softened cream cheese (cut into small cubes and gently folded in), and use pepper jack cheese instead of cheddar. The cream cheese creates pockets of melty goodness .

4. Herb and Onion Muffins

Add ¼ cup finely chopped onion (sautéed until soft and cooled) and increase the herbs—try fresh parsley, dill, and thyme alongside the chives. These are elegant and flavorful .

5. Broccoli Cheddar Muffins

Fold in ½ cup finely chopped cooked broccoli (leftover steamed broccoli works perfectly). Use extra cheddar cheese. It’s like broccoli cheddar soup in muffin form !

6. Breakfast Sausage Muffins

Add ½ cup cooked and crumbled breakfast sausage to the mixture. These are perfect for breakfast on the go.

7. Vegan Version

Use vegan mashed potatoes (made with plant-based milk and butter), substitute the egg with a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water), and use your favorite vegan shredded cheese .

Serving Suggestions

For Breakfast or Brunch

Serve warm alongside scrambled eggs, crispy bacon, and fresh fruit for a hearty breakfast . They’re also perfect with a simple green salad for brunch.

As a Side Dish

These muffins are incredible alongside roasted chicken, grilled steak, or baked fish . They replace both the starch and the vegetable if you add herbs or broccoli.

For Lunch

Pack them in lunchboxes—they’re delicious at room temperature . Pair with a thermos of soup for a satisfying meal.

With Dips

Serve these muffins with sour cream, ranch dressing, or even ketchup for dipping. They’re perfect for parties and game day spreads .

For Holiday Tables

These muffins are a wonderful addition to Thanksgiving, Easter, or Christmas dinner. They’re easier than making separate servings of mashed potatoes, and they look beautiful on a platter .

Storage and Reheating

Refrigerator Storage

Store leftover mashed potato muffins in an airtight container in the refrigerator for up to 4-5 days . Place parchment paper between layers to prevent sticking.

Freezer Instructions

These muffins freeze beautifully for up to 3 months .

1. Cool muffins completely.
2. Arrange in a single layer on a baking sheet and freeze until solid (about 1-2 hours).
3. Transfer frozen muffins to a freezer-safe bag or container, separating layers with parchment paper.
4. Label with date and contents.

Reheating Instructions

· Oven (Best method): Reheat on a baking sheet at 350°F for 8-10 minutes until warmed through and edges are crispy again .
· Air Fryer: Reheat at 350°F for 3-4 minutes .
· Microwave: Quick but will soften the crispy edges. Microwave for 30-60 seconds .
· Toaster Oven: Perfect for reheating 1-2 muffins at a time.
