This Cajun steak pasta is what I make when I want something that feels a little bougie but tastes like comfort food.
A rich, garlicky cream sauce coats every ridge of the rigatoni, and seared sirloin tips with a dark Cajun crust cut right through all that richness.
It’s the kind of dinner that feels like a splurge and comes together in about thirty minutes, which is exactly the balance I want on a night when I’m not going out but I still want dinner to feel like an occasion.
The steak is what makes it work. Sirloin gets seared hard for 60 to 90 seconds a side and pulled at 135°F, so it’s tender when it goes into the pasta and still tender after reheating — lean cuts turn rubbery fast, and the timing is what protects it.
The Cajun seasoning builds a crust that becomes the flavor base for the whole sauce, and the fond it leaves in the pan gets deglazed with beef broth.
And the sauce is the part that surprised me. It’s built on light cream cheese instead of heavy cream, which sounds like a compromise and isn’t — cream cheese holds its emulsion through the microwave, so the pasta is still glossy on day three instead of sitting in a pool of separated fat.
It’s creamy and spicy and a little tangy from the lemon at the end, and it’s the version I’d hand you first if you told me creamy pastas never survive the fridge.
Why This Recipe Works
Searing the sirloin in a single layer over high heat builds the crust. Crowding the pan drops the temperature and steams the meat instead of searing it. Cook in two batches, 60 to 90 seconds per side, to build a dark Cajun crust that becomes the flavor base for the whole sauce.
Pull the steak at 135°F to keep it tender. Sirloin is lean, and lean meat overcooks fast. Pulling it at 135°F with carryover to about 145°F gets you medium, which is the sweet spot for sirloin, and the steak finishes warming in the sauce rather than cooking further.
Light cream cheese helps the sauce survive reheating. Heavy cream breaks when microwaved—the fat separates and pools. Cream cheese is a stabilized emulsion that holds together through the microwave and stays glossy across four days.
Add the Parmesan over low heat so it melts smoothly. If you heat Parmesan too hard, it turns grainy and stringy. Turning the pan to low and adding it gradually is what makes the sauce silky instead of clumpy.
Cooking the pasta 2 minutes under the package time lets it finish in the sauce. Pasta absorbs liquid as it sits, and pasta that starts fully cooked in the sauce turns to paste by day two. Two minutes under means it lands at the right texture and stays there.
Ingredients That Matter
Top sirloin or sirloin cap, cut into 1-inch cubes against the grain. Sirloin is lean and can be tough if it’s a cheaper grade or cut with the grain. Top sirloin is the best choice, and cutting against the grain shortens the muscle fibers so it stays tender.
Low-sodium Cajun seasoning, or half the amount if it’s regular. Cajun seasoning blends vary a lot in salt, and regular blends can overpower the whole dish. Start with the low-sodium version and taste before adding more.
Light cream cheese (Neufchâtel), softened. The sauce depends on it. Cold cream cheese in a hot pan seizes into lumps, so let it sit out while the pasta cooks and whisk it in thoroughly.
How to Make It
1. Cook the pasta. Bring a large pot of salted water to a boil and cook 8 oz of high-protein rigatoni for 2 minutes, according to the package directions. Reserve ½ cup of pasta water, drain, and set aside.
2. Season the steak. Pat 1.75 lbs of sirloin cubes dry with paper towels, then toss with 1½ tablespoons low-sodium Cajun seasoning until evenly coated.
3. Sear the steak. Heat 1 tablespoon of avocado oil in a large skillet over high heat until shimmering. Add the steak in a single layer, working in two batches, and sear 60 to 90 seconds per side, until a dark crust forms and the internal temperature reaches 135°F. Transfer to a plate and keep the juices.
4. Build the sauce. Reduce the heat to medium. Add 4 cloves of minced garlic and cook for 30 seconds. Pour in ¾ cup of low-sodium beef bone broth, scraping up the browned fond. Whisk in 6 oz softened cream cheese until smooth, then simmer for 2 minutes.
5. Add the Parmesan. Turn the heat to low and gradually whisk in ¾ cup of freshly microplaned Parmesan until melted and glossy. Whisk in ¼ cup of the reserved pasta water to thin the sauce to a silky consistency that coats the back of a spoon.
6. Toss and finish. Add the rigatoni, the steak tips, and the pan juices. Toss gently for 60 seconds, until the pasta is coated and the steak is warmed through. Off the heat, stir in 1 teaspoon lemon juice, 2 tablespoons parsley, and black pepper. Taste and adjust salt.
7. Serve. Serve immediately, topped with toasted panko for crunch, or divide among 4 containers and refrigerate.
Tips and Troubleshooting
The sauce turned grainy. The Parmesan went in over too much heat. Turn the pan to low before adding it, and whisk it in gradually.
The sauce broke on reheating. You used heavy cream instead of cream cheese. Cream cheese is what makes the sauce survive the microwave.
The steak came out tough. It was cooked past 135°F, or it was cut with the grain. Pull it at 135°F and slice against the grain.
The pasta dried out in the container. It wasn’t cooked for the package time, or it wasn’t tossed in enough sauce. Cook it 2 minutes under and use the full ¼ cup of pasta water in the sauce.
It tastes too salty. Cajun seasoning, broth, and parmesan all carry salt. Use low-sodium versions of each and taste before adding anything.
The pasta turned mushy. Chickpea and lentil pasta go soft faster than wheat. Fold them in close to serving rather than hours ahead.
The leftovers are dry. The sauce thickens when cold. Reheat covered with a splash of broth for 75 to 90 seconds.
Storage and Reheat
Store in an airtight container in the refrigerator for up to 4 days.
The sauce thickens as it chills, so reheat covered with a splash of broth for 75 to 90 seconds.
The pasta and sauce freeze for up to 3 months, though the pasta softens on thawing and the steak loses some texture. Best within three days.

FAQ
Can I use a different cut of steak? Yes. Ribeye and strip work but are fattier. Flank and skirt work but need to be sliced thin against the grain. Top sirloin is the best balance of leanness and tenderness.
Can I make this with chicken instead? Yes — it works as a Cajun chicken pasta. Use 2 lbs of chicken breast cut into 1-inch pieces, sear to 160°F, and keep the rest of the recipe the same.
Can I use regular rigatoni instead of high-protein? Yes, but the protein drops from 48g to about 38g per serving. The high-protein pasta is doing a lot of work here.
Can I add sausage? Yes. Brown 8 oz of sliced andouille or Cajun sausage with the garlic and reduce the Cajun seasoning slightly, since sausage is already seasoned. It’s a good way to make a creamy Cajun sausage pasta.
Why did my sauce separate? Heavy cream was used, or the Parmesan went in over too much heat. Cream cheese and low heat are the fixes.
Can I make this ahead for meal prep? Yes — it holds up for four days. Cook the pasta 2 minutes under, pack it in containers, and reheat with a splash of broth.

Closing
The flash-sear and the cream cheese sauce are the two things that make this pasta work — everything else is Cajun seasoning and Parmesan.
It’s the one I’d hand you first when you want a creamy pasta that doesn’t fall apart in the container.
Make it once, and tell me whether you ate it fresh or saved it for day three.
