Storage/Reheating
Store leftover cheese puffs in an airtight container in the refrigerator for up to 3 days.
To reheat, place them in an oven or air fryer at 350°F (175°C) for 5–8 minutes until heated through and crispy again. Avoid microwaving if possible, as it may make them soft instead of crisp.
You can also freeze cooked cheese puffs for up to 2 months. Reheat directly from frozen in the oven until hot and crispy.
FAQs
Can I use instant mashed potatoes?
Yes, as long as they are thick and not too watery. If the mixture feels too soft, add a little extra flour to help bind it.
What type of cheese works best?
Cheddar and mozzarella are popular choices, but you can use any good melting cheese such as Monterey Jack or Colby.
Why are my cheese puffs falling apart?
The mixture may be too wet. Try adding a bit more flour or chilling the mixture for 20–30 minutes before shaping.
Can I bake these instead of frying?
Yes, bake them at 400°F (200°C) for about 18–22 minutes, flipping halfway through for even browning.
Can I make the mixture ahead of time?
Yes, you can prepare the mixture and refrigerate it for up to 24 hours before shaping and frying.
How do I know when the oil is ready for frying?
The oil should reach about 350°F (175°C). If you don’t have a thermometer, drop in a small piece of the mixture—if it sizzles and rises to the top, the oil is ready.
Can I air fry these cheese puffs?
Yes, air fry at 375°F (190°C) for about 10–12 minutes, shaking or turning halfway through.
What dipping sauces pair well with these?
Ranch dressing, sour cream, marinara sauce, spicy aioli, or honey mustard are all great options.
Can I freeze them before frying?
Yes, shape the puffs and freeze them on a baking sheet. Once solid, transfer to a freezer bag and fry directly from frozen, adding a few extra minutes to the cooking time.
How can I make them gluten-free?
Substitute the all-purpose flour with a gluten-free flour blend designed for baking.
