What is alfredo sauce?
The Alfredo sauce has Italian origins, and it's traditionally associated with fettuccine pasta. In its original form, it was made only with butter, parmesan cheese and residual pasta water, but the variation with double cream/heavy cream is quite common now.

Ingredients overview

- spaghetti - the amounts listed are for 2 generous portions
- raw king prawns / shrimp - or indeed any other seafood
- double / heavy cream - it's what makes the sauce super creamy
- garlic - the more, the merrier
- black pepper - freshly ground is just the best!
- grated parmesan cheese - parmesan adds a gorgeous sharp kick to the sauce
- salt - to taste
- chopped parsley - I used fresh, dried all ok
- butter - either salted or unsalted, I prefer salted as it adds extra flavour
Easy swaps
The alfredo sauce works with pretty much any pasta shape, so if you don't have spaghetti, you could use tagliatelle, linguine, and so on.
I used raw prawns, but if you use ready-cooked prawns, you can just add them at the same time you add the cream, so they can heat up, no need to cook them any further, otherwise they will become rubbery.
Parmesan cheese can be swapped for Pecorino Romano, or any other hard cheese of your choice - I do recommend using cheese though, it adds a lot of flavour.
Step-by-step photos and instructions
- cook the pasta according to the packet instructions
- once it's ready, reserve 2 tablespoons of the pasta water and drain the rest
- melt the butter, add the prawns, season them with salt and pepper, and add the chopped garlic

- cook the prawns until they turn pink, then remove them from the pan
- add the cream and grated parmesan, and season with black pepper
- toss the pasta in, give everything a good mix and garnish with chopped parsley

Expert tips
I don't usually cook with wine, but if you do, you can add a splash of white wine to the pan before adding the cream, although the dish is absolutely beautiful without it too.
When the prawns turn pink on one side, flips them onto the other side, and remove them from the pan once it's completely pink, if you leave it for longer, it texture becomes quite rubbery.
We want it al dente, so the pasta is cooked, but not too soft, as it cooked further once it's added to the hot sauce.
Other alfredo recipes
I absolutely love this shrimp alfredo, it's rich, it's comforting, and so easy to make. If you are not a big fan of shrimp/prawns, there are so many other variations you can try.

Or, why not, just have it without any fish/meat or meat alternative added, just the pasta and sauce, it's still delicious!

Notes
- You can season the shrimp before adding it to the pan, some garlic granules or a bit of chilli are a nice choice, but otherwise, just salt and pepper will do.
- I don't usually cook with wine, but if you do, you can add a splash of white whine to the pan before adding the cream, although the dish is absolutely beautiful without it too.
- The parmesan gives a nice flavour, and cuts the richness of the cream and butter, so you use it. If you don't have parmesan, choose any other strong-flavoured hard cheese, for that extra sharpness.
