Ingredients
Method
- Bring a large pot of water to a boil, salt it generously and cook the pasta al dente according to the directions on the package. Reserve a couple of cups of pasta water before draining.
- Meanwhile, heat the olive oil in a large, deep pan and melt the butter in it.
- Add the onion and cook for 2-3 minutes over medium heat.
- Stir in the garlic, lemon zest, red chili flakes and lemon juice and cook for another minute.
- Transfer the cooked pasta to the pan and use a pair of kitchen tongs to toss it. Add some of the reserved pasta water if the sauce looks too thick.
- Stir in the smoked salmon and fresh parsley, then season to taste and serve immediately.

Notes
Pasta Water: I cannot stress enough how important it is to reserve that pasta water.
That starchy liquid is my secret weapon for creating a silky, cohesive sauce that clings to every strand of linguine.
Don't skip it or you'll end up with a dry, clumpy dish.
Smoked Salmon Timing: Add the smoked salmon at the very end, just before serving.
If you cook it too long, it becomes tough and loses its delicate, silky texture.
I like to gently fold it in so it warms through but stays tender.
Lemon Zest First: Always zest your lemon before you juice it.
I learned this the hard way when I tried to zest a squishy, juiced lemon and ended up with a mess.
The zest adds a bright, aromatic pop that the juice alone can't provide.
Spice Adjustment: The red chili flakes give this pasta a gentle warmth, not a fiery kick.
If you're sensitive to heat, start with just a pinch.
For my family, I sometimes leave them out entirely and let everyone add their own at the table.
Make Ahead Tip: This pasta is best enjoyed immediately, but if you have leftovers, store them in an airtight container in the fridge for up to two days.
When reheating, add a splash of water or milk to bring back the creamy consistency, as the pasta will absorb the sauce overnight.
Serving Suggestion: I love to finish this dish with a generous sprinkle of fresh parsley and a few extra cracks of black pepper.
For a complete meal, I often serve it alongside a simple green salad with a lemon vinaigrette to echo the citrus flavors.
Pasta Shape: While linguine is my go-to here, any long pasta like spaghetti or fettuccine works wonderfully.
I've even used short pasta like penne in a pinch, and it was still delicious, though the sauce clings a bit differently.
