Steps
Tap an underlined word for a quick explanation.
the cheddar and set it aside.
Grate. Grating means rubbing food across the holes of a grater to make fine shreds or flakes. It spreads cheese, garlic or ginger evenly through a dish so it melts right in.
How you’ll know: Even shreds fall off the back of the grater, and you stop while the piece is still big enough to hold.
Put the macaroni, water, butter, salt and garlic powder in the Instant Pot, stir, and press the pasta under the water.
Scatter the frozen squash over the top. Don’t stir.
Lock the lid, set the valve to Sealing, and pressure cook on high for 4 minutes.
Timer: 4 min
Dolly’s tip: It takes about 10 minutes to come up to pressure before the countdown starts. That’s normal.When it beeps, carefully turn the valve to Venting with a long spoon, keeping your hand and face away from the steam.
Mash the squash into the pasta with a potato masher or the back of a big spoon until it into a sauce.
Melt. Melting means gently heating something solid, like butter or cheese, until it turns liquid. Low or medium heat keeps it from browning or burning.
How you’ll know: It’s smooth and liquid, and butter may foam a little but hasn’t turned brown.
Golden brown. Golden brown is the color of good toast, somewhere between yellow and light brown. It means the outside is cooked and crisp but not burnt.
How you’ll know: It looks like toast and smells toasty; dark brown with a bitter smell means it went too far.
Dolly’s tip: It melts right into the sauce. A few small bits left are fine.Stir in the milk, then the cheddar a handful at a time, until creamy. Serve right away.
