Instructions

Step 1: Boil the Pasta
Bring a large pot of salted water to a boil. Add pasta and cook according to package instructions until al dente. Reserve 1/2 cup pasta water, then drain pasta.
Step 2: Toast the Sunflower Seeds
While pasta cooks, toast sunflower seeds in a dry skillet over medium heat for 3–4 minutes until golden and fragrant. Let cool slightly.
Step 3: Pulse the Pesto
In a food processor, combine toasted sunflower seeds, basil, garlic, Parmesan, olive oil, lemon juice, salt, and pepper. Pulse until a coarse paste forms, scraping down sides as needed.
Step 4: Emulsify the Sauce
Add water and blend until smooth and creamy. Adjust consistency with more water if needed.
Step 5: Toss and Combine
Return drained pasta to the pot over low heat. Add pesto and cream, tossing to coat. Add reserved pasta water a little at a time until the sauce reaches your desired consistency.
Step 6: Finish and Season
Taste and adjust seasoning with salt, pepper, or lemon juice as needed. Serve immediately, garnished with extra Parmesan and fresh basil if desired.

Zusatztipps für die Zubereitung

To ensure the best results, do not skip toasting the seeds, as this releases their essential oils and provides the signature nutty flavor. When processing the pesto, remember to scrape down the sides of the bowl to ensure every seed is perfectly blended into the sauce.

Varianten und Anpassungen

For a vegan version, substitute the Parmesan cheese with nutritional yeast and use a plant-based cream. You can also boost the nutritional value by adding cooked vegetables like peas, spinach, or roasted cherry tomatoes. For those with dietary restrictions, this recipe works excellently with gluten-free pasta varieties.

Serviervorschläge

Serve this pasta warm, ideally in pre-heated bowls to maintain the sauce's creaminess. A garnish of fresh basil and extra cheese adds a final touch of elegance. This dish pairs exceptionally well with a crisp white wine such as Sauvignon Blanc.

Recipe FAQs

Can I make this pesto ahead of time?

Yes, the pesto can be prepared up to 2 days in advance and stored in an airtight container in the refrigerator. Keep a thin layer of olive oil on top to prevent browning. Prepare the pasta and combine just before serving for best texture.

What pasta shapes work best with this pesto?

Long, thin pasta like spaghetti or linguine works beautifully, as does penne or fusilli. Choose pasta with texture to help the pesto cling. Avoid very delicate shapes that might break under the creamy sauce.

How do I make this dairy-free?

Replace Parmesan cheese with nutritional yeast for a similar umami flavor, and swap heavy cream for unsweetened plant-based cream such as oat or cashew. The pesto will be equally delicious and creamy.

Why toast the sunflower seeds?

Toasting develops a deeper, richer flavor that enhances the nutty notes of the pesto. It takes just 3-4 minutes and significantly improves the overall taste and aromatic quality of your sauce.

Can I add vegetables to this dish?

Absolutely. Stir in cooked peas, fresh spinach, roasted cherry tomatoes, or sautéed mushrooms during the final tossing step. These additions boost nutrition and complement the pesto flavors beautifully.

What should I do if the sauce is too thick?

Add reserved pasta water gradually while tossing until you reach your desired consistency. Start with a tablespoon at a time. The pasta water's starch helps the sauce cling to noodles while maintaining proper texture.
