Spinach Pesto Orzo is my go-to dish when I want something green and creamy in under half an hour. It is light yet satisfying and always earns enthusiastic requests at picnics or as a fresh main for a busy weeknight.

I first whipped this up on a spring evening with random greens from the fridge and was floored by how much flavor you get from a handful of spinach. Since then I have served it for family birthdays and quick lunches alike and it never disappoints.

Ingredients

  • Orzo pasta: This rice shaped pasta cooks quickly and soaks up pesto beautifully Choose a brand with a short cook time and good texture
  • Fresh baby spinach: The star green gives bright color and loads of nutrients Tender leaves blend down smoothly and are less bitter than mature spinach
  • Fresh basil leaves: Classic pesto flavor comes from sweet earthy basil Pick vibrant bunches with no black spots
  • Grated Parmesan cheese: Adds salty nuttiness Opt for real Parmigiano Reggiano for best flavor
  • Toasted pine nuts or walnuts: These provide irresistible richness Toast just until golden for full flavor
  • Garlic: Two cloves add essential aromatic punch Use firm fresh cloves for the least bitterness
  • Extra virgin olive oil: Makes everything lush and creamy Use a flavorful brand you like on salads
  • Lemon juice: The acidity lifts the pesto and keeps it bright
  • Salt and black pepper: Balance all the flavors Freshly cracked pepper is best at the end
  • Optional extra Parmesan and pepper: to finish because more cheese is always welcome

The olive oil in the pesto brings everything together and makes each bite silky with a subtle peppery bite I have always loved watching my niece sprinkle her own parmesan on top because it tells me kids and adults both really adore this dish My favorite part is seeing the orzo grab onto every speck of green sauce

Storage Made Simple

Store any leftovers in a well sealed container in the fridge for up to three days For best texture let it come up to room temperature or give it a gentle zap in the microwave If the sauce thickens stir in a drizzle of olive oil or splash of water to refresh
