Your Complete Cooking Timeline
Step one, cook that fettucini noodles just till al dente. You follow package instructions cause it works real good. Drain 'em and set aside while you get to work on the steak.
Step two, season your steak with half the steak seasoning, about a tablespoon. Rub it in well.
Step three, heat up 2 tablespoons avocado oil in a skillet over medium-high. When it’s hot, add your steak and sear for 3 to 4 minutes each side till it’s cooked as you like. Take it off the heat and let it rest, gotta keep those juices.
Step four, in that same skillet, melt 3 tablespoons butter and toss in 5 cloves minced garlic. Sauté for a minute or two, till super fragrant and kinda golden.
Step five, pour in heavy cream and half and half, stir it up so it gets creamy. Add your remaining steak seasoning, cracked pepper, and green onions. Let it simmer, 5 to 7 minutes till sauce thickens a bit.
Step six, add in your cooked fettucini noodles, toss to coat each strand in that buttery sauce. Then slice your steak into bite-sized bits and stir them in.

Last step, add remaining butter, stir till melted and the sauce is all rich and smooth. Serve it up hot with extra green onions if you like. Dinner done in about 30 minutes, dang that’s fast!
Smart Shortcuts for Busy Days
- Grab pre-minced garlic to cut chopping time, it works real good and saves you some knife work.
- Use store-bought steak seasoning if you’re not in the mood to mix your own, it’s alright for a quick fix.
- Cook noodles the day before and refrigerate; toss ‘em in the sauce this recipe calls for when ready.
- Buy pre-sliced steak or leftover steak from the deli to save grilling or searing time.
- Use the pressure cooker to sauté garlic and make sauce right there instead of messy extra pans.
What It Tastes Like Fresh From the Pot
The first bite hits your tongue with that creamy buttery sauce soaking each noodle. You sense the garlic’s warmth but without being overpowering, just right. The parmesan adds a nutty, salty kiss that lingers delightfully.
Then you get a bit of juicy steak surprise in every forkful, tender and bold with seasoning love. The green onions give a fresh snap that kinda brightens the whole thing up, balancing richness with a slight oniony pop.
Everything melts together with a smooth buttery hint that sticks with you. You feel every flavor in a hug, rich but not too heavy. The sauce clings tight, distracting you from anything plain or boring.
Making It Last All Week Long
If you wanna save leftovers, store them in airtight containers with tight lids. That keeps the sauce creamy and the steak moist.
Refrigerate leftovers within 2 hours, keep them for up to 3 days. Reheat gently on stove or microwave to keep sauce from breaking.
You can also freeze portions in freezer-safe containers. Thaw overnight in the fridge and reheat slow so sauce stays silky.
Try storing the pasta and steak separately if you plan to freeze; that way you get less mushy noodles when reheated. It works better that way for longer storage.
Everything Else You Wondered About
- Can I use other types of pasta? Heck yeah, just adjust cooking time for noodles accordingly.
- What if my pressure cooker doesn’t have a float valve? You gotta watch for a pressure indicator light or sound instead. Every cooker’s a bit different.
- Can I swap out steak for chicken? Sure thing, but adjust cooking times cause chicken cooks faster inside a pressure cooker.
- Do I have to use avocado oil? Nope, olive oil works but watch the heat cuz it burns faster.
- Is natural release necessary? For this recipe, yes, it lets sauce thicken slow and keeps steak tender.
- How do I know when to replace the sealing ring? If you notice steam leaking out erratically or valve hiss sounds when it shouldn’t, that ring might need swapping.
