Ingredients
- 250 g (8.8 oz) dried pasta (such as spaghetti, linguine, or fettuccine)
- 1 tablespoon olive oil
- 20 g (1 tablespoon) unsalted butter
- 1 medium onion, very finely chopped
- 2 cloves garlic, finely chopped or minced
- Juice of 1 fresh lemon (approximately 30 ml)
- 100 g (3.5 oz) pistachio kernels, processed into a coarse meal in a food processor
- 20 g (0.7 oz) extra pistachio kernels, roughly chopped with a knife, for garnishing
- 200 ml (1 cup) double cream (heavy cream)
- 6 fresh basil leaves, roughly shredded
- 30 g (¼ cup) grated Parmesan cheese (or a vegetarian hard cheese equivalent)
- A generous handful of fresh rocket salad (arugula), about 50 g (1.7 oz)
- Salt and freshly ground black pepper, to taste
Instructions
- Begin by bringing a large pot of water to a vigorous boil. Once boiling, season generously with salt – the water should taste like the sea, as this is the only chance to season the pasta itself. Add the 250 g (8.8 oz) of pasta and cook according to the package instructions until it reaches a perfect al dente texture, meaning it should still have a slight bite to it. Before draining, carefully reserve approximately 120 ml (½ cup) of the starchy pasta water; this will be essential for achieving the ideal sauce consistency.
- While the pasta is cooking, turn your attention to crafting the luxurious pistachio sauce. Heat the 1 tablespoon of olive oil in a large, deep skillet or frying pan over medium heat. Add the 20 g (1 tablespoon) of unsalted butter and allow it to melt and combine with the olive oil. This fat base provides a rich foundation for the aromatics.
- Introduce the finely chopped medium onion to the skillet. Cook gently for 3-4 minutes, stirring occasionally, until the onion softens and becomes translucent without taking on any significant color. This slow sautéing extracts the natural sweetness from the onion, building a foundational flavor.
- Stir in the 2 finely chopped garlic cloves. Continue to cook for just another minute until the garlic releases its fragrant aroma. Be vigilant at this stage to prevent the garlic from browning or burning, as scorched garlic can impart a bitter taste to the sauce.
- Pour in the fresh juice of 1 lemon. The bright acidity from the lemon will provide a crucial counterpoint to the richness of the cream and pistachios. Immediately follow by adding the 100 g (3.5 oz) of food processor-chopped pistachio kernels and the 200 ml (1 cup) of double cream. Stir all these ingredients thoroughly to combine.
- Lower the heat to a gentle simmer and allow the sauce to cook for 1-2 minutes, stirring occasionally. During this time, the sauce will begin to thicken slightly as it heats through and the flavors meld together. If you find the sauce becoming too thick, a small splash of the reserved pasta water can be added now to thin it.
- Remove the skillet from the heat. Stir in the 6 roughly shredded fresh basil leaves; adding them at the end preserves their vibrant color and delicate aroma. Using tongs, transfer the al dente cooked pasta directly into the pan with the sauce. Toss the pasta vigorously to ensure every strand is beautifully coated in the creamy pistachio sauce. If the sauce appears too dense or clings too much to the pasta, add a dash more of the reserved pasta water, a tablespoon at a time, until the desired consistency is achieved.
- Finally, stir in the 30 g (¼ cup) of grated Parmesan cheese (or vegetarian hard cheese) and the generous handful of fresh rocket salad (arugula). The cheese will melt slightly, adding a wonderful savory depth, while the rocket offers a refreshing, peppery bite. Taste the dish and adjust the seasoning with salt and freshly ground black pepper as needed. Serve immediately, garnished with the extra knife-chopped pistachios for added texture and visual appeal.
Tools You’ll Need
- Large pot for cooking pasta
- Large, deep skillet or frying pan
- Food processor (optional, for chopping pistachios)
- Sharp knife
- Cutting board
- Measuring cups and spoons
- Lemon juicer (optional)
- Tongs or pasta server
Essential Success Tips
- Toasting your pistachios lightly before processing can enhance their nutty flavor even further, adding a deeper dimension to the sauce.
- Always salt your pasta water generously; this is the primary way to season the pasta itself and greatly impacts the final taste of the dish.
- Don't overcook the garlic! It should be fragrant, not browned, to avoid any bitterness.
- Reserve enough pasta water; it's a chef's secret weapon for emulsifying sauces and adjusting consistency.
- Add fresh herbs like basil at the very end to preserve their vibrant flavor and color, as excessive heat can diminish their quality.
Professional Cooking Secrets
- For an extra layer of complexity, infuse your olive oil with a crushed garlic clove or a pinch of chili flakes before adding the onion; strain it out before the butter for subtle background notes.
- If you want to intensify the pistachio flavor and color, blanch the pistachios for a minute, then rub off their skins before processing. This yields a brighter green and purer pistachio taste.
- To make the sauce even silkier, consider adding a tablespoon of crème fraîche along with the double cream. Its slight tanginess can add another dimension of flavor and luxurious texture.
Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stovetop with a splash of water or cream.
- Variations: For a richer sauce, you can add a tablespoon of mascarpone cheese. For a lighter version, use single cream and a bit more pasta water.
- Vegetarian Option: Ensure your hard cheese is suitable for vegetarians if catering to those dietary needs.
Frequently Asked Questions
Can I use pre-shelled pistachios?
Yes, absolutely! Pre-shelled pistachio kernels are perfect for this recipe. Just ensure they are unsalted so you can control the seasoning of the sauce yourself.
What kind of pasta works best with this sauce?
Long pasta shapes like spaghetti, linguine, fettuccine, or even tagliatelle work wonderfully as they allow the creamy sauce to cling beautifully to each strand. Shorter shapes like penne or fusilli can also be used.
Can I make this sauce ahead of time?
The sauce can be prepared a few hours in advance and gently reheated. However, for the best flavor and texture, especially with the fresh basil and rocket, it's recommended to combine the sauce with freshly cooked pasta just before serving.
