Creamy Cajun Steak Fettuccine
Ever had steak and pasta on the same plate and thought, yes, this is exactly the level of unnecessary I was hoping for?
This creamy Cajun steak fettuccine brings juicy sliced steak, silky pasta, and a peppery sauce with enough heat to keep the whole bowl from feeling flat.
Have you ever looked at a bowl of creamy pasta and decided it needed steak on top?
Fair enough.
The fettuccine gets coated in a Cajun cream sauce with garlic, black pepper, and just enough spice to give it some edge.
Then the steak goes on in thick slices so you still get that proper seared crust instead of losing it in the sauce.
A few blistered tomatoes or peppers work really well here too, especially against all that richness.
The main thing is keeping the steak juicy and the sauce loose enough to cling to the pasta without turning gluey.
Once both of those are right, there really isn’t much left to argue with.

Ingredient Notes
Steak
Sirloin works really well here because it cooks quickly and slices nicely.
Ribeye is also great if you want something a little richer.
Just do not use a very thin cut, because it can overcook too fast and lose that juicy texture.
Roasted Red Peppers
You can use jarred roasted red peppers or roast your own.
Jarred peppers are absolutely fine for this recipe and keep things easier.
Make sure you drain them well and slice them into strips.
Cajun Seasoning
Different Cajun blends vary a lot in salt and heat.
Taste as you go, especially when seasoning the sauce.
You can always add more, but it is harder to fix a sauce that has gone too far.
How to Make Creamy Cajun Steak Fettuccine
1. Cook the pasta
- Bring a large pot of well salted water to a boil.
- Add the fettuccine and cook until al dente according to the package instructions.
- Before draining, scoop out about 1 cup of the pasta water.
- Drain the pasta and set it aside.
2. Season the steak
- Pat the steak dry with paper towels.
- Rub it with the olive oil.
- Sprinkle over the Cajun seasoning, garlic powder, salt, and black pepper.
- Rub the seasoning in well on both sides.
3. Sear the steak
- Heat a large skillet over medium high heat.
- Once hot, add the steak.
- Cook for about 3 to 4 minutes per side for medium rare, depending on thickness.
- If you prefer medium, cook it a little longer.
- Transfer the steak to a plate and let it rest for at least 5 to 10 minutes.
4. Start the sauce
- In the same skillet, lower the heat to medium.
- Add the butter.
- Once melted, stir in the garlic and cook for about 30 seconds.
- Add the sliced roasted red peppers.
- Stir in the Cajun seasoning, smoked paprika, and chilli flakes if using.
- Cook for 1 to 2 minutes so the flavours wake up.
5. Make it creamy
- Pour in the chicken stock and stir, scraping up any browned bits from the bottom of the pan.
- Add the cream and bring it to a gentle simmer.
- Stir in the parmesan a little at a time.
- Let the sauce cook for 2 to 3 minutes until smooth and slightly thickened.
- Add black pepper and taste for salt.
6. Add the pasta
- Tip the cooked fettuccine into the sauce.
- Toss until the pasta is fully coated.
- If the sauce looks too thick, add a splash of the reserved pasta water.
- Keep tossing until it looks glossy and silky.
7. Slice the steak
- Slice the rested steak against the grain into strips.
- Try not to slice it too early or all the juices will run out onto the board.
8. Assemble and serve
- Divide the creamy fettuccine between bowls.
- Arrange the sliced steak over the top.
- Scatter over chopped parsley.
- Finish with extra parmesan if you like.
- Serve straight away while everything is hot and glossy.
Tips for the Best Result
Do not overcook the steak
This pasta is much better with juicy steak than with grey, overdone steak.
Remember that it keeps cooking slightly as it rests.
A little pink in the middle works beautifully here.
Save that pasta water
A splash of pasta water can rescue the whole texture of the sauce.
It helps the sauce loosen up without turning watery and makes it cling to the fettuccine much better.
Grate your own parmesan
Pre grated parmesan does not always melt as smoothly.
Freshly grated parmesan gives you a silkier sauce and a better flavour.
Use a big enough skillet
Once the pasta goes in, space matters.
You want enough room to toss everything properly so the fettuccine gets coated instead of clumping together.
Easy Variations
You can tweak this recipe without ruining what makes it good.
Here are a few easy swaps.
Swap the steak
- Use chicken breast or boneless chicken thighs
- Use prawns for a quicker version
- Use sliced smoked sausage for something heartier
Add vegetables
- Baby spinach
- Mushrooms
- Sweetcorn
- Sautéed onions
Make it spicier
- Add extra chilli flakes
- Use a hotter Cajun seasoning
- Stir in a tiny spoonful of hot sauce
Lighten it a little
- Use half cream and half milk
- Use less parmesan
- Add extra roasted peppers to keep the sauce feeling full
What to Serve With It
This pasta does not need much on the side because it is already a full meal.
Still, if you want to round it out, these work well.
- Garlic bread
- A crisp green salad
- Roasted broccoli
- Simple sautéed green beans
- Extra roasted peppers on the side
Storage and Reheating
To Store
Let the pasta cool, then transfer it to an airtight container.
Store in the fridge for up to 3 days.
If possible, store the sliced steak separately so it stays a little nicer when reheated.
To Reheat
Reheat gently in a skillet or saucepan over low heat.
Add a splash of milk, cream, or stock to loosen the sauce.
Stir often until warmed through.
Avoid blasting it over high heat because the sauce can turn too thick and the steak can go tough.
Frequently Asked Questions
Can I use another type of pasta?
Yes.
Tagliatelle, linguine, or even penne will work.
Fettuccine is especially good because the wide noodles hold onto the creamy sauce so well.
What cut of steak is best?
Sirloin is a solid choice.
Ribeye is richer and more tender.
Strip steak also works nicely.
Just pick a cut that sears well and can be sliced thinly after resting.
Is this very spicy?
Not really.
It has warmth and a gentle kick, but the cream and parmesan mellow everything out.
If you are sensitive to heat, start with less Cajun seasoning and skip the chilli flakes.
Can I make it ahead?
This is best eaten fresh.
The sauce is at its glossiest right after cooking.
If you need to prep ahead, cook the steak and slice the peppers in advance, then make the sauce and pasta closer to serving.
Can I use milk instead of cream?
You can, but the sauce will be lighter and not as velvety.
If you use milk, a little cream cheese or extra parmesan can help give the sauce more body.
Final Thoughts
This creamy Cajun steak fettuccine really earns its place in the dinner rotation.
It has that rich, restaurant style feel, but the method is straightforward and the ingredient list is not fussy.
The steak gives it substance, the roasted red peppers bring sweetness, and the creamy parmesan sauce pulls the whole thing together in the most comforting way.
It is bold without being too heavy handed.
And once those ribbons of fettuccine are coated in that sauce, it is very hard to stop at one bowl.
