Ingredients
- 250 g (8.8 oz) pasta (e.g., spaghetti, fettuccine)
- 1 tablespoon (15 ml) olive oil
- 20 g (1 tablespoon) unsalted butter
- 1 medium onion, finely chopped
- 2 garlic cloves, finely chopped
- Juice of 1 lemon (approximately 30 ml or 2 tablespoons)
- 100 g (3.5 oz) pistachio kernels, chopped in a food processor (plus extra pistachios for garnishing, chopped with a knife)
- 200 ml (1 cup) double cream (heavy cream)
- 6 basil leaves, roughly shredded
- 30 g (¼ cup) grated parmesan (or vegetarian hard cheese)
- Rocket salad (arugula), a handful (approximately 30 g or 1 oz)
Instructions
- Bring a large pot of water to a rolling boil, ensuring it is generously salted before adding the pasta. Cook the pasta al dente according to the instructions on its package, as it will continue to cook slightly when combined with the sauce. Before draining, reserve approximately 120-180 ml (½-¾ cup) of the starchy pasta water; this will be crucial for adjusting the sauce's consistency.
- While the pasta cooks, begin preparing the sauce. Heat the olive oil in a large, deep skillet or pan over medium heat. Once shimmering, add the unsalted butter and allow it to melt completely. The combination of oil and butter helps prevent the butter from burning.
- Add the finely chopped onion to the skillet. Cook over medium heat for 3-4 minutes, stirring occasionally, until the onion softens and becomes translucent. Avoid browning the onion, as this will alter the delicate flavor profile of the sauce.
- Stir in the finely chopped garlic and continue to cook for another minute. You will notice a fragrant aroma developing; be careful not to burn the garlic, as it can quickly become bitter.
- Next, pour in the fresh lemon juice, which will add a bright, zesty counterpoint to the richness of the cream and pistachios. Immediately follow with the food processor-chopped pistachios and the double cream. Stir well to combine all ingredients.
- Lower the heat to a gentle simmer and cook for 1-2 minutes, stirring continuously, until the sauce begins to thicken slightly. The goal is a luscious, coat-the-back-of-a-spoon consistency.
- Stir in the roughly shredded fresh basil leaves. Their aromatic quality is best preserved by adding them at the end of the cooking process. Transfer the cooked al dente pasta directly into the pan with the sauce. Toss vigorously to ensure every strand of pasta is thoroughly coated. If the sauce appears too thick, add a dash of the reserved pasta water, a tablespoon at a time, until it reaches your desired consistency.
- Finally, remove the pan from the heat and stir in the grated Parmesan cheese and the handful of fresh rocket salad. The residual heat will wilt the rocket slightly and melt the cheese. Taste and season with salt and freshly ground black pepper as needed. Serve immediately, garnished with the knife-chopped pistachios for extra texture and visual appeal.
Tools You’ll Need
- Large pot for pasta
- Large, deep skillet or frying pan
- Food processor or chopper
- Colander
- Measuring spoons and cups
- Grater (for Parmesan)
- Sharp knife and cutting board
Essential Success Tips
- Always salt your pasta water generously; it's your first chance to season the pasta itself.
- Cook pasta to true al dente; it will absorb more sauce and finish cooking in the pan.
- Don't skip reserving pasta water; it's starchy liquid gold for emulsifying and loosening sauces.
- Toast pistachios lightly before processing for a deeper, more pronounced nutty flavor.
- Use fresh, high-quality basil and Parmesan for the best aromatic and savory notes.
Professional Cooking Secrets
- For an even richer sauce, toast the pistachios gently in a dry pan for a few minutes before chopping. This enhances their natural oils and flavor.
- Consider adding a tiny pinch of red pepper flakes with the garlic for a subtle warmth that complements the nuttiness of the pistachios.
- If you prefer a silkier, smoother sauce, you can briefly blend a portion of the finished sauce (before adding the pasta, cheese, and arugula) with an immersion blender to break down the pistachios further, then combine with the remaining sauce.
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 vegetable broth to loosen the sauce.
- Variations: For a richer, deeper flavor, you can briefly toast the whole pistachio kernels in a dry pan before processing. Add grilled chicken or shrimp for a non-vegetarian option.
- Vegetarian Option: Ensure to use a vegetarian hard cheese instead of traditional Parmesan if strict vegetarianism is required.
Frequently Asked Questions
Can I use pre-shelled pistachios?
Absolutely! Pre-shelled pistachios are perfect for this recipe and will save you preparation time. Just ensure they are unsalted.
What kind of pasta works best with this sauce?
Long pasta shapes like spaghetti, fettuccine, or linguine are excellent as they beautifully carry the creamy sauce. Short pasta like penne or fusilli can also work well if you prefer.
Can I make this sauce ahead of time?
While the sauce can be made a few hours in advance, it's best when prepared fresh and tossed immediately with hot pasta. The fresh basil and arugula are also best added right before serving for optimal flavor and texture.
