Lemon Salmon & Zucchini Noodles
I used to think pasta night was non-negotiable. Like, structurally. You get home tired on a Tuesday, the answer is pasta. That was the deal.
Then I found out the jarred lemon cream sauce I’d been using every week had 14g of sugar in it. In a sauce. That tasted savoury. I checked the label three times. I was not misreading it.
This is the swap that made me stop missing pasta. Zucchini ribbons take two minutes with a peeler, the salmon goes in a hot pan while you make the sauce, and the whole thing is done faster than the pasta would have been anyway. My husband calls it “the better version.” I’m choosing to take it as a compliment.

Ingredients
Serves 2 · Scale as needed
- 2 salmon fillets (approx. 150g each), skin on
- 2 ⇄ large zucchini, peeled into ribbons ⇄ the swap
- 2 tbsp extra virgin olive oil
- 2 tbsp capers, drained
- 3 tbsp fresh lemon juice (about 1 large lemon)
- ½ tsp lemon zest
- 1 small garlic clove, finely minced
- 1 tbsp cold unsalted butter
- Sea salt and black pepper
- Fresh parsley or dill, to finish
Instructions
-
1
Use a vegetable peeler to peel the zucchini lengthways into wide, flat ribbons. Stop when you hit the seedy core. Pat them gently with paper towel and set aside. Don’t salt them yet — that draws water and makes them soggy.
-
2
Pat the salmon fillets completely dry with kitchen paper. Season generously with sea salt and black pepper on both sides. Dry fish = crispy skin. Wet fish = sad steamed fish.
-
3
Heat 1 tbsp olive oil in a heavy pan over medium-high heat until shimmering. Place salmon skin-side down and press gently for the first 30 seconds. Cook 4–5 minutes without touching it. Flip and cook 2 more minutes. Rest on a plate.
-
4
In the same pan on low heat, add remaining oil, garlic, and capers. Cook 1 minute. Add lemon juice and zest, stir. Take off the heat and swirl in the cold butter until the sauce looks glossy and slightly thickened. This is the French trick. It takes 30 seconds.
⇄ Swap NoteThe cold butter replaces the cream and thickens the sauce beautifully without any added sugar. The jarred version uses sugar to balance acidity — fresh lemon and butter don’t need it.
-
5
Add the zucchini ribbons to the pan with the sauce, off the heat. Toss gently for 30 seconds — just warm, still with bite. Zucchini waits for no one: serve immediately.
-
6
Twist the zucchini ribbons into nests on each plate. Place the salmon on top, skin-side up so it stays crispy. Spoon remaining sauce over. Scatter fresh parsley or dill.
Why I Made This Swap
The sugar in jarred lemon cream sauce is there to balance acidity — but when you make it yourself with good olive oil, real lemon, capers, and a knob of cold butter, you don’t need it. The flavour is brighter and cleaner. Zucchini ribbons reduce the total carbohydrates significantly, but honestly I did it because I wanted something that didn’t leave me horizontal on the sofa afterwards. Both reasons are valid.
Common Mistakes
- Cooking the zucchini too long. 30 seconds in residual heat. That’s it. Any longer and you have a puddle.
- Skipping the dry pat on the salmon. Moisture is the enemy of crispy skin. Pat it dry or it steams instead of sears.
- Using bottled lemon juice. This dish has four ingredients of flavour. The lemon has to be real.
Storage
Best eaten immediately. If you have leftovers, store the salmon separately from the zucchini — the ribbons release water overnight. Reheat the salmon gently in a pan and toss the zucchini fresh with a squeeze of lemon.

Frequently Asked Questions
Can I use a spiralizer instead of a peeler?
Yes, but ribbons are better with this sauce — they catch more of the lemon-butter. Spiralized noodles are thinner and wilt faster. Either works, ribbons are my preference.
Can I use a different fish?
Sea bass, cod, or trout all work well. You want a fish with enough body to stand up to the bold lemon-caper sauce.
Is this actually filling without pasta?
Yes — 34g of protein per serving is what keeps you full. I was sceptical too. Make it on a Tuesday night and see if you miss the pasta. I genuinely don’t.
