Ingredients
- Short or long pasta (whatever you have)
- A large handful of fresh spinach
- 1 small garlic clove
- Olive oil
- A small handful of nuts or seeds (pine nuts, walnuts, or sunflower seeds)
- Finely grated hard cheese
- Salt and black pepper
- A splash of pasta cooking water
Ingredients Overview
- Spinach
Creates a softer, milder pesto compared to traditional basil. - Garlic
Adds a sharp note that balances the greens. - Nuts or seeds
Bring texture and a subtle richness to the sauce. - Olive oil
Helps blend everything into a smooth, cohesive pesto. - Grated cheese
Adds depth and a slightly salty finish.
Why This Recipe Works
- Quick blending keeps flavor fresh
Minimal processing prevents the spinach from becoming dull or heavy. - Pasta water binds the sauce
The starch helps the pesto coat the pasta evenly without separating. - Warm pasta absorbs flavor better
Tossing immediately helps the sauce cling and distribute evenly.
Instructions
- Bring a pot of salted water to a boil and cook the pasta until just tender. Scoop out a little pasta water before draining.
- While the pasta cooks, place the spinach, garlic, nuts or seeds, and grated cheese into a blender or food processor.
- Add a pinch of salt and blend briefly. Drizzle in olive oil until the pesto becomes loose but still textured.
- Transfer the drained pasta back to the warm pot. Add the spinach pesto and a splash of reserved pasta water.
- Toss gently until the pasta is coated and glossy. Adjust seasoning with salt and black pepper.
- Serve immediately, plain or with a little extra cheese on top. For extra freshness, stir in a small handful of raw spinach right before serving.
Tips for Best Results
- Use a generous amount of spinach
It reduces significantly when blended, so don’t be afraid to add more. - Add olive oil gradually
This helps control the texture and prevents the pesto from becoming too thin. - Taste before mixing with pasta
Adjust salt and cheese early for better overall balance.
Common Mistakes to Avoid
- Over-blending the pesto
It can become too smooth and lose its fresh texture. - Using too little pasta water
The sauce may feel dry and not coat properly. - Adding pesto to very hot, dry pasta
Without a bit of water, it can clump instead of spreading evenly.
Substitutions & Variations
- Swap spinach for arugula or mixed greens
Adds a slightly more peppery flavor. - Use different nuts or go nut-free
Sunflower seeds or pumpkin seeds work well. - Add protein
Grilled chicken or chickpeas can turn it into a fuller meal.
Storage & Leftovers
- Store in the fridge up to 2 days
Keep in an airtight container to preserve freshness. - Add a splash of water when reheating
Helps loosen the sauce and restore texture. - Best eaten fresh
The pesto is brightest right after making.
