Your Simple Ingredient Checklist
- 1 lb sirloin or ribeye steak - cut into 1-inch cubes for tender bites.
- 10 oz rigatoni pasta - classic shape holds the sauce nice.
- 1 tablespoon Cajun seasoning - plus extra to sprinkle on top if you like heat.
- 2 tablespoon unsalted butter - divided to boost that buttery flavor.
- 1 tablespoon olive oil - helps get the perfect sear.
- 2 cloves garlic, minced - adds a punch of aroma to the sauce.
- 1 cup heavy whipping cream - makes the sauce rich and creamy.
- ¾ cup freshly grated Parmesan cheese - packed with sharp cheesy tang.
- ½ cup shredded mozzarella cheese (optional) - for extra gooeyness if you’re feeling fancy.
The Full Pressure Cooker Journey
First thing you wanna do is bring a big pot of salted water to a boil. Toss in the rigatoni and cook until al dente, following package instructions. Drain it well and set it aside while you work on the steak and sauce.
Next, season your steak cubes good with Cajun seasoning, plus a pinch of salt and black pepper. You want that flavor locked in from the start. Heat your skillet on medium-high and add olive oil and 1 tablespoon of butter.
Once the fat’s smoking hot, arrange the steak pieces in a single layer. Let ‘em sear for about 2 or 3 minutes per side until you get that nice brown crust. Pull the steak from the pan and set aside for now.
Lower the heat to medium and toss in the remaining butter. Add your minced garlic and sauté it just for 30 seconds or so until the kitchen smells amazing. Don’t burn it or you’ll get bitterness.
Pour in the heavy cream and bring it to a gentle simmer. Stir in Parmesan and mozzarella cheeses, mixing until the sauce looks smooth and velvety. This is the broth depth kicking in, making the base for your cheesy rigatoni.
Now, add your cooked rigatoni right to the sauce and give it a good stir so every noodle gets coated. Return those seared steak tips back to the skillet and toss everything gently to combine.
Give it one last taste. Add more Cajun seasoning, salt, or pepper if you wanna kick it up a notch. Serve it hot, maybe with some extra Parmesan sprinkled on top if you’re feeling generous.

Valve Hacks You Need to Know
- Make sure your sealing ring is snug before you start cooking — no steam escapes that way.
- Watch the steam cues carefully once you hit pressure build, it’s a sign your food is cooking right.
- If you’re in a hurry, do a quick release right after the timer goes off to speed up dinner.
- Let your pressure cooker natural release for a few minutes if you want your steak extra tender without drying out.
- Keep a kitchen towel handy when opening the lid to catch any last bursts of hot steam safely.
What It Tastes Like Fresh From the Pot
The first bite hits you with creamy cheesy goodness all over the rigatoni. You feel that smoky Cajun spice kinda sneak up and dance on your taste buds. It’s rich in flavor but balanced just right where the cream cools the heat down a bit.
The steak tips are tender with a slight crust from that sear, juicy and bursting with seasoning. Each piece kinda melts in your mouth but still holds texture. The sauce clings to both pasta and meat making every bite feel special.
You catch the Parmesan and mozzarella working together to make this sauce super smooth and gooey. It’s comfort food done right with a little spicy kick that keeps you guessing if you wanna another plate or just slow savor it.

Keeping Leftovers Fresh and Ready
Once your meal’s done, let it cool to room temp before storing. This keeps moisture just right so your rigatoni doesn’t get mushy or dried out.
Use airtight containers to keep the cheesy sauce from drying on your leftovers. You wanna keep that sauce creamy and flavorful when reheating.
For reheating, warm on low in the microwave or on the stovetop with a splash of milk or water to bring back creamy texture. Avoid overheating or your sauce might separate.
Your Most Asked Questions Answered
- Can I use other cuts of steak? Sure thing. Just pick cuts that cook tender and slice them into cubes for even cooking.
- What if I don’t have heavy cream? You can swap in half and half, but sauce won’t be quite as thick or rich.
- Can I make this spicier? Absolutely. Add more Cajun seasoning or toss in a pinch of cayenne pepper for extra heat.
- Can I cook everything together in the pressure cooker? Nope, pasta cooks quicker so it’s best done in the pot separately. Sauce and steak get all the love in the skillet.
- How do I know when my steak is done? Cooking times vary but searing the outside then finishing in skillet till it’s your preferred doneness works best.
- Can I freeze leftovers? Yep you can, but cheese sauces sometimes change texture after freezing. Thaw slow and reheat gently.
