Save to Pinterest The first time I made this lemon spinach spaghetti, it was actually a Tuesday night rescue mission. I had half a bag of wilting spinach, a lonely lemon on the counter, and zero energy for anything elaborate. Now it is become my go-to when I want something that feels fancy but honestly takes less than half an hour from start to finish.
Last spring my sister came over for a catch up dinner and I threw this together at the last minute. She actually stopped mid conversation, fork hovering in the air, and asked what was in the sauce because it tasted like something from a restaurant. That moment of watching someone genuinely enjoy food you just threw together is pretty hard to beat.
Ingredients
- Thin spaghetti: The thinner surface area catches more of that silky sauce, though regular spaghetti works fine too
- Salt: Generously salt your pasta water until it tastes like the sea
- Fresh baby spinach: Baby spinach is tender and wilts beautifully without any tough stems to remove
- Garlic: Freshly minced garlic releases more oils and flavor than pre-chopped
- Lemon zest and juice: Both are essential, the zest brings aromatic brightness while the juice adds tang
- Unsalted butter: Starting with unsalted lets you control exactly how salty the final dish becomes
- Heavy cream: Creates that luscious restaurant style texture that milk simply cannot achieve
- Grated Parmesan: Freshly grated melts into the sauce better than pre-shredded which has anti-caking agents
- Black pepper: Freshly cracked makes a huge difference here
Instructions
- Cook the pasta to perfection:
- Bring a large pot of generously salted water to a rolling boil, add the spaghetti, and cook until al dente. Before draining, scoop out about 120ml of that starchy pasta water and set it aside.
- Build the aromatic base:
- While the pasta bubbles away, melt the butter in a large skillet over medium heat. Add the minced garlic and let it soften for just one minute until fragrant, watching carefully so it does not brown or turn bitter.
- Wilt the spinach:
- Toss in the fresh spinach and stir for 2 to 3 minutes until it has completely wilted down. Stir in the lemon zest so those citrus oils can bloom in the heat.
- Create the creamy sauce:
- Pour in the heavy cream and bring everything to a gentle simmer. Add the lemon juice and Parmesan, stirring until the cheese melts and the sauce thickens enough to coat a spoon.
- Bring it all together:
- Add the drained spaghetti directly to the skillet and toss vigorously to coat every strand. If the sauce seems too thick, gradually add splashes of that reserved pasta water until it turns silky and clings to the pasta.
- Season and serve:
- Taste and add generous black pepper plus salt if needed. Plate immediately while the sauce is glossy and hot, finishing with extra lemon zest and Parmesan.
Save to Pinterest This recipe has saved me countless times when unexpected guests arrive or I just need comfort food that does not require hours of effort. There is something about the combination of bright lemon and warm cream that makes people pause and savor every bite.
Making It Your Own
Sometimes I add a handful of frozen peas during the last minute of pasta cooking for pops of sweetness. Other times I sprinkle in red pepper flakes if I want a little warmth that balances the cream.
Perfect Pairings
A crisp white wine like Sauvignon Blanc cuts through the richness beautifully. For a complete meal, serve with a simple green salad dressed in vinaigrette to balance the creamy pasta.
Getting Ahead
You can zest the lemon and grate the Parmesan up to a day ahead. The garlic can also be minced and stored in a small container.
- Keep the lemon juice fresh by squeezing it just before cooking
- Warm your serving bowls in the oven for a few minutes
- Have your garnish prepped so you can serve immediately
