Why I Love This Recipe
This recipe is everything I want in a pasta dish: rich without being heavy, comforting yet fresh. The pistachios add a buttery depth that plays perfectly with the brightness of basil and lemon juice. It’s also a versatile base—delicious warm, room temp, or chilled for lunch the next day. Plus, it’s vegetarian-friendly, making it ideal for potlucks or dinner parties with mixed diets.
Ingredients
For the Pistachio Pesto:
- ½ cup shelled pistachios (unsalted)
- 1 cup fresh basil leaves
- 1 clove garlic
- ¼ cup grated Parmesan cheese
- ¼ cup extra virgin olive oil
- 1 tbsp lemon juice
- Salt & pepper to taste
For the Pasta:
- 12 oz pasta (spaghetti, penne, or your favorite shape)
- ½ cup reserved pasta water
- Extra Parmesan (for serving)
- Crushed pistachios (for garnish)
Ingredient Notes & Swaps
- Pistachios: If you’re out, try cashews or walnuts for a similarly rich texture.
- Cheese: A hard cheese like Pecorino Romano also works if you like a saltier bite.
- Garlic: Use roasted garlic for a sweeter, more mellow flavor.
- Basil: Sub in a mix of spinach and basil if you’re running low.
- Make it Vegan: Use nutritional yeast instead of Parmesan and skip any dairy garnish.
Step-by-Step Instructions
1. Cook the Pasta
Bring a large pot of salted water to a boil. Cook your pasta according to package directions until al dente. Reserve ½ cup of pasta water before draining.
2. Make the Pistachio Pesto
In a food processor, combine pistachios, basil, garlic, Parmesan, lemon juice, salt, and pepper. Blend until the mixture becomes a coarse paste. While the processor is running, slowly drizzle in olive oil until the pesto is smooth and creamy.
3. Combine Pasta & Pesto
Add the drained pasta to a large bowl or skillet. Toss with the pistachio pesto, gradually stirring in reserved pasta water until the sauce evenly coats the pasta and reaches your desired creaminess.
4. Serve & Enjoy
Plate the pasta, then top with additional Parmesan and crushed pistachios for that gourmet finish.
Tips for Success
- Use High-Quality Olive Oil: It’s a key player in the flavor of your pesto.
- Toast the Pistachios: Lightly toasting them enhances their natural oils and intensifies the flavor.
- Don’t Overcook the Pasta: A firm bite helps the sauce cling better.
