FAQs

What pasta works best?

Elbow macaroni is traditional, but shells or cavatappi also work well.

Can I use pre-shredded cheese?

Yes, but block cheese melts better and gives a smoother sauce.

Is it spicy?

Not unless you add hot sauce or spicy cheese.

Do I need to drain the pasta?

No, the water is absorbed and helps create the sauce.

Can I double the recipe?

Yes, just be sure not to fill past the Instant Pot’s max line.

Is it creamy without cream?

Yes, whole milk gives a nice balance of richness and lightness.

Can I make it gluten-free?

Use gluten-free pasta and adjust cook time slightly.

How do I avoid clumps of cheese?

Add cheese in small handfuls and stir thoroughly.

What if it’s too thick?

Stir in more milk until it reaches your desired consistency.

Can I make it ahead?

Best served fresh, but you can prep and reheat with added milk.
