Step‑by‑Step Instructions for Mashed Potato Muffins
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Mashed Potato Muffins cook evenly and achieve a beautiful golden-brown crust. While the oven is heating, gather your ingredients and equipment, including a mixing bowl and a muffin tin, so you’re ready to dive into the fun of baking these delightful treats.
Step 2: Prepare the Muffin Tin
Grease a muffin tin generously with butter or cooking spray to prevent your muffins from sticking. Ensure that each cup is well-coated; this step is crucial for easy release after baking. A standard muffin tin will yield about 12 muffins. Having a well-prepared tin sets the stage for your savory success!
Step 3: Mix the Wet Ingredients
In a large mixing bowl, combine your mashed potatoes, milk, sour cream, and eggs. Use a whisk or spatula to thoroughly mix these ingredients until they reach a smooth and creamy consistency. This mixture will serve as the flavorful base for your Mashed Potato Muffins, so make sure everything is blended well with no lumps.
Step 4: Combine the Dry Ingredients
Next, gently fold in the all-purpose flour, baking powder, garlic powder, onion powder, salt, and pepper. Stir these ingredients with a spatula or wooden spoon just until combined; be careful not to overmix, as this can lead to dense muffins. The goal is to create a unified batter that holds all the flavors together.
Step 5: Add Cheese and Optional Green Onions
Once your batter is formed, it’s time to add the shredded cheese and chopped green onions, if using. Fold these ingredients into the mixture gently, ensuring even distribution without overworking the batter. The cheesy goodness will melt beautifully, enhancing the flavor of your Mashed Potato Muffins, while green onions add a touch of freshness.
Step 6: Fill the Muffin Cups
Using a spoon or scoop, fill each muffin cup about three-quarters full with the batter. This allows room for the muffins to rise without overflowing. Smooth the tops of each muffin slightly for an even appearance. Don’t worry; a little mess is part of the fun as you prepare your tasty creations!
Step 7: Bake to Perfection
Place the muffin tin in the preheated oven and bake for 20-25 minutes. Keep an eye on them; they should turn a lovely golden color and rise beautifully. To check for doneness, insert a toothpick into the center of a muffin; if it comes out clean, your Mashed Potato Muffins are ready to shine!
Step 8: Cool and Serve
Once baked, remove the muffin tin from the oven and allow the muffins to cool for about 5 minutes. This resting time helps them set and makes them easier to remove. Afterward, gently lift the muffins out of the tin and transfer them to a wire rack to cool completely. Enjoy these delightful Mashed Potato Muffins warm or at room temperature!

Tips for the Best Mashed Potato Muffins
-
Mix Gently: Avoid overmixing the batter to ensure your Mashed Potato Muffins stay fluffy. Overmixing can lead to dense, heavy muffins that lack texture.

-
Custom Add-Ins: Feel free to personalize your muffins! Incorporate cooked bacon bits, sautéed vegetables, or even different cheeses for a unique flavor twist.
-
Check Freshness: Ensure your baking powder is fresh for the best rise. Old baking powder may prevent your muffins from achieving that lovely fluffy texture.
-
Store Properly: Keep any leftovers in an airtight container in the fridge for up to three days. Reheating them in the oven will restore their delightful texture and flavor.
Make Ahead Options
These Mashed Potato Muffins are perfect for meal prep! You can make the batter and refrigerate it up to 24 hours in advance, allowing the flavors to meld together beautifully. Simply mix the mashed potatoes, milk, sour cream, and eggs with the dry ingredients, and then fold in the cheese and green onions as directed.

Mashed Potato Muffins Recipe FAQs
How do I choose the best mashed potatoes for this recipe?
Absolutely! The best mashed potatoes for these muffins are those that are well-seasoned and fluffy. Ideally, they should be leftover from a previous meal. If you’re making them fresh, avoid adding too much liquid or butter, as the muffins rely on a thicker consistency for the perfect texture.
How long can I store Mashed Potato Muffins in the refrigerator?
Very! You can store your Mashed Potato Muffins in an airtight container in the refrigerator for up to 3 days. They’ll hold their fluffy texture, but it’s best to reheat them in the oven or microwave just before serving for maximum enjoyment!
Can I freeze Mashed Potato Muffins? If so, how?
Yes, you can! Start by allowing the muffins to cool completely after baking. Then, wrap each muffin in plastic wrap or foil and place them in a freezer-safe container or bag. They can be frozen for up to 3 months. When ready to enjoy, simply reheat from frozen in the microwave or bake them at 350°F (175°C) for about 10-15 minutes.
What if my muffins are too dense?
If your muffins turn out dense, it may be due to overmixing the batter. Be sure to combine the ingredients only until they’re just incorporated and avoid using too much flour. For extra fluffiness, you can also try adding an additional teaspoon of baking powder to the mix next time.
Can I make these muffins dairy-free or gluten-free?
Absolutely! To make the muffins dairy-free, simply use plant-based milk and substitute the sour cream with dairy-free yogurt. For gluten-free muffins, you can use a 1:1 gluten-free flour blend, ensuring your baking powder is also gluten-free. They will be just as delicious!
Are there any considerations for pets or allergies with this recipe?
Very! While the ingredients are generally safe for human consumption, keep in mind that onions—especially raw or cooked—can be toxic to pets, including dogs and cats. If you plan to share these muffins with furry friends, it’s best to omit the chopped green onions or any other potentially harmful ingredients.
