How to Cook Lemon Spaghetti with Toasted Walnuts

Cooking Lemon Spaghetti with Toasted Walnuts is quite straightforward and allows you to enjoy the process. The key is to time everything perfectly, so each component is ready at the same moment. Let’s dive into the steps!
- Start by bringing a large pot of water to a boil. Add a generous amount of salt; it should taste like the sea! Once boiling, add your spaghetti and cook according to the package directions, usually around eight to ten minutes for al dente. As the pasta cooks, it will absorb the salt, which will enhance the flavor of the dish.
- While the pasta cooks, heat a small sauté pan over medium-high heat. Once hot, add the walnuts. Toast them for about five minutes, stirring occasionally, until they are golden brown and fragrant. Be careful not to let them burn; you want that perfect nutty aroma!
- Once the walnuts are ready, remove them from the heat and set them aside. This will allow them to cool slightly while you finish the pasta.
- When the spaghetti is cooked to your liking, reserve about half a cup of the cooking water, then drain the pasta. This starchy water will help bind the sauce.
- Return the drained spaghetti to the pot over low heat. Add in the butter, olive oil, and kosher salt. The heat will melt the butter and combine it with the olive oil to create a rich sauce.
- Next, stir in the zest and juice from the lemons, along with the toasted walnuts. Toss everything together to coat the pasta evenly. The aroma of lemon will fill your kitchen!
- If the sauce seems too thick, gradually add the reserved pasta water, a little at a time, until you reach your desired consistency. You want it creamy but not runny.
- Once everything is well combined and heated through, take the pot off the heat. Give it one last gentle toss to ensure every strand of spaghetti is coated.
- Serve immediately in warm bowls, garnishing with a few more toasted walnuts and a sprinkle of lemon zest if desired. Enjoy your Lemon Spaghetti with Toasted Walnuts!
Things Worth Knowing
- Don’t overcook the pasta: Keep an eye on the spaghetti; it should be al dente for the best texture.
- Toasting nuts makes a difference: Always toast your walnuts before adding them; it enhances their flavor immensely.
- Use fresh lemons: Fresh lemons yield the best flavor, so avoid the bottled juice if possible.
- Adjust the seasoning: Feel free to taste and adjust the kosher salt or add a pinch of black pepper for more flavor.
