Recipe FAQ Section

Can I use a different type of pasta?

Yes, short pasta shapes like fusilli, penne, or rigatoni work well to hold the creamy sauce. Whole-wheat or gluten-free varieties can be used as needed.

How do I achieve perfectly caramelised onions?

Cook sliced onions in olive oil over medium heat, stirring occasionally for 15–20 minutes until they turn golden and sweet. Patience is key.

What can I substitute for feta cheese?

For a different flavor, try using a soft goat cheese or vegan feta alternative. Adjust seasoning to taste as needed.

Is it possible to add extra vegetables?

Absolutely! Toss in baby spinach or arugula just before serving for extra freshness and a nutritional boost.

How should leftovers be stored?

Let leftovers cool, then transfer to an airtight container and refrigerate for up to 2 days. Reheat gently, adding a splash of water if needed.
