You sense that tender pull, the way the macaroni swells and the broccoli softens just right under pressure. That smell creeping out from the pot is enough to make you forget about your day real quick. This here is definitely one of those meals that feels like a warm hug after a long day of city noise and rushing errands.

How It All Comes Together Step by Step

Start by melting your butter on medium heat right inside your big pot. You gotta get a nice base going before anything else.
Toss in your diced onion and carrot. Sauté them about 5 to 7 minutes till they soften up and start smelling sweet and cozy.
Next, stir in the minced garlic with your dry mustard, and nutmeg or chili flakes if you’re using those. Let that cook just a minute so the flavors wake up.
Sprinkle in the flour while stirring all the time so you don’t get lumps. After a minute or two you got yourself a roux. That’s gonna thicken the whole soup real good.
Slowly whisk in the vegetable broth, making sure it’s smooth and lump-free. Bring that up to a simmer, and then add your garlic powder.
Close your lid and seal that sealing ring tight. Lock it up and bring to pressure. Your float valve will pop up telling you it’s sealed and cooking. Cook for about 6 minutes, then do a quick release to drop the pressure fast.
Open the lid carefully and stir in elbow macaroni and broccoli pieces. Put the lid back on and cook under pressure for another 3 minutes.
Quick release again and open to find beautifully tender pasta and broccoli.
Pour in the half and half and stir in your sharp cheddar cheese till it melts all creamy smooth. Season with salt and pepper and you’re ready to dig in.
Time Savers That Actually Work
Pre-diced veggies from the store can be your best friend here, especially onions and carrots. No chopping means you’re already halfway done before you start cooking.
Use your pressure cooker’s quick release method to avoid standing around waiting for pressure to drop naturally. It saves you a bunch of time when you’re hungry.
If you wanna speed up the melting, shred your cheese while the pressure is building. Then when it’s ready, just dump it in and stir fast.
That First Bite Moment

You scoop up that creamy bowl and notice how the smooth cheddar melts in your mouth with a velvety richness. It’s the kinda comfort you just can’t fake.
The little nubs of broccoli peek through, giving a fresh gentle crunch that makes each mouthful less heavy.
You kinda feel that background warmth from the mustard and pinch of chili flakes with every bite, it’s subtle but it works real good.
Every forkful reminds you this is the kind of lunch or dinner you’ll wanna cozy up with on a slow weekend or cold night.
Keeping Leftovers Fresh and Ready
Portion your leftovers into airtight containers so they stay fresh in the fridge for up to 3 days. It keeps the soup from drying out or picking up fridge smells.
You can freeze individual portions too for longer storage. Just thaw in the fridge overnight and reheat gently on the stove or microwave.
If reheating, add a splash of broth or half and half to bring back that creamy softness. Stir it around so it heats evenly without drying.
