How to Make Mashed Potato Cheese Puffs
Step 1: Prep the Mixture
In a mixing bowl, combine mashed potatoes, cheddar, Parmesan, flour, and one beaten egg. Season with salt and pepper. Mix until smooth and chill for 15 minutes (this helps with shaping).
Step 2: Shape the Puffs
Scoop out tablespoon-sized portions and roll them into balls. If you’re adding a cheese cube or bacon piece inside, now’s the time to tuck it into the center.
Step 3: Set Up the Coating Station
Prepare two shallow bowls:
- Bowl 1: Beaten egg for dipping.
- Bowl 2: Breadcrumbs mixed with Parmesan.
Dip each puff into the egg wash, then coat it in the breadcrumb mixture, pressing gently for an even crust.
Step 4: Bake to Perfection
Place the coated balls on a lined baking sheet and bake at 400°F (200°C) for 18–20 minutes, or until golden and crisp.
Step 5: Serve and Enjoy
Let cool for a few minutes, then serve warm with your favorite dips—think marinara, ranch, or garlic aioli.
Easy Variations
- Herb it Up: Add chopped parsley, chives, or thyme for freshness.
- Bring the Heat: Mix in cayenne, smoked paprika, or chili flakes.
- Gluten-Free: Use GF breadcrumbs and flour.
- Air Fryer Method: Cook at 375°F (190°C) for 10–12 minutes, flipping halfway.
- Stuff It: Hide a surprise cube of mozzarella, bacon, or jalapeño inside each puff.
Pro Tips
- Chill First: If the mixture is too soft, refrigerate the shaped balls for 15–20 minutes before coating.
- Breadcrumb Boost: Homemade or panko breadcrumbs offer the crispiest results.
- Reheat Right: Store leftovers in the fridge (up to 2 days) and reheat in an oven or air fryer to keep them crispy.
Serving Ideas
- Elegant Starter: Garnish with microgreens or edible flowers.
- Brunch Favorite: Serve with coffee, fresh juice, or a fruit salad.
- Snack Board Hero: Add to a spread with sliders, veggie sticks, and dips.
