• Pasta noodles – any shape works: spaghetti, penne, fusilli, or legume-based pastas for higher protein.
• Pesto – use store-bought or homemade. Basil, walnut, parsley or arugula pestos all work well.

2. Step 2: Drain the pasta and transfer it to a large bowl.

3. Step 3: Add the pesto and toss the noodles until well coated.

Top Tips:

• Avoid overcooking the pasta so it stays firm and holds the sauce.
• This dish is versatile—serve warm as a quick dinner or chilled as a salad for lunches.

Pesto pasta can be a healthy, balanced meal depending on the ingredients. Adding tuna or another protein and fresh vegetables boosts nutrition and makes it more filling.

Pesto pairs well with pasta, rice, fish, chicken and roasted vegetables. It also works as a spread, dip or pizza topping.

Freezing is not recommended; pasta can become mushy and the texture changes after thawing.

Store leftovers in an airtight container in the refrigerator for up to 5 days.
