Make Ahead Tips

How to Make Parmesan Mashed Potato Puffs
Step 1: Preheat the Oven and Prep the Muffin Tin
Preheat your oven to 400°F. Spray all 12 cups of your muffin tin with non-stick spray to prevent sticking.
Step 2: Mix the Wet Ingredients
In a large bowl, add 2 cups cold mashed potatoes, 2 large eggs, ¼ cup whole milk, and 2 tablespoons sour cream. Stir until smooth.

Step 3: Add Cheeses and Seasonings
Add 1 cup shredded sharp cheddar, ½ cup grated parmesan, ¼ tsp garlic powder, ¼ tsp onion powder, ¼ tsp black pepper, and 2 tablespoons chopped chives. Stir gently until just combined.

Step 4: Fill the Muffin Tin
Scoop the mixture evenly into the 12 muffin cups, filling each about ¾ full. Smooth the tops lightly with the back of a spoon.

Step 5: Bake Until Golden and Set
Bake in the preheated oven for 25 minutes, or until tops are golden and edges look crispy. Let cool 5 minutes in the pan before serving.

Why This Recipe Works (Quick Science)
Eggs and cheese help bind the cold mashed potatoes and give structure while baking. The fats in the cheese and sour cream create richness and crisp edges. Baking in a muffin tin gives each puff even browning and that perfect golden crust.
Common Mistakes
- Using warm mashed potatoes — they make the mix too runny
- Not greasing the muffin tin enough — cheese sticks easily
- Overbaking — they can dry out quickly, so check at 23 minutes
- Under-seasoning — taste your mashed potatoes first
What to Serve With
- Roasted chicken or turkey
- A crisp green salad
- Soup like tomato or broccoli cheddar
- Breakfast sausage or bacon
- Steamed veggies
FAQ
Can I use instant mashed potatoes?
Yes, just make them thicker than usual so the mix holds its shape.
Can I freeze these?
Yep! Bake, cool, then freeze. Reheat in oven for best texture.
Do I have to use chives?
Nope! Try parsley, green onions, or skip entirely.
What if I don’t have sour cream?
Use plain Greek yogurt or even cream cheese.
Leftovers and Storage
Store in an airtight container in the fridge for up to 3 days. Reheat in the oven or toaster oven at 350°F for 8–10 minutes to bring back the crisp edges. You can also freeze them — just thaw and reheat in the oven.
