This commercial pesto contains rapeseed oil (canola oil), a highly inflammatory seed oil that damages health. Our clean version uses 100% organic extra virgin olive oil instead, plus eliminates the potato starch stabilizer for a truly natural pesto with superior flavor and nutrition.

Why This Recipe is Seed Oil Free
Commercial Finest Pesto With Fresh Basil from Tesco often contains inflammatory seed oils like canola, soybean, or sunflower oil. This homemade version replaces them with healthier fats like butter, ghee, coconut oil, or avocado oil — giving you the same great taste without the processed oils.

Instructions
Step 1. Toast the pine nuts: Spread 200g organic pine nuts in a dry skillet over medium-low heat. Stir constantly for 3-4 minutes until fragrant and lightly golden. This develops their buttery flavor and prevents the pesto from tasting flat. Transfer to a plate and cool completely - warm nuts will melt the cheese and create a greasy texture.
Step 2. Prepare the garlic: Peel 6-8 garlic cloves (about 30g total) and roughly chop them. If your garlic is very pungent, start with 4 cloves and taste-test later. The garlic will mellow during processing but shouldn't overpower the basil.
Step 3. Wash and dry the basil: Gently wash 500g fresh organic basil leaves in cool water, then spin in a salad spinner or pat completely dry with paper towels. Any water will dilute the pesto and cause it to separate. Remove any thick stems but small tender stems are fine.
Step 4. Start the base: In a food processor, pulse the toasted pine nuts and chopped garlic together 8-10 times until roughly chopped but not powdered. You want some texture remaining. Add 15g Redmond Real Salt and pulse 2-3 more times to distribute.
Step 5. Add basil gradually: Add about 1/3 of the basil leaves to the processor and pulse 5-6 times. Add another 1/3, pulse again, then add the remainder. This prevents the basil from turning into mush. Scrape down sides as needed. The mixture should look roughly chopped but cohesive.
Step 6. Stream in the oil: With the processor running, slowly drizzle in 700ml organic extra virgin olive oil through the feed tube over 60-90 seconds. The slow addition creates proper emulsification. Stop when the mixture forms a thick, spreadable paste with some texture - it shouldn't be completely smooth.
Step 7. Fold in cheeses and finish: Transfer pesto to a large bowl. Finely grate 250g Parmigiano-Reggiano and 150g Pecorino Romano using a microplane or fine grater - pre-grated cheese has anti-caking agents that affect texture. Fold cheeses into pesto by hand with a wooden spoon. Add 30ml fresh lemon juice and taste for balance. Adjust salt if needed.
Step 8. Final storage and usage: Transfer to clean glass jars, pressing plastic wrap directly onto the surface to prevent oxidation. Top each jar with a thin layer of olive oil for extra protection. Store refrigerated for up to 10 days or freeze in ice cube trays for 6-month storage. Use 1-2 tablespoons per serving of pasta, or spread on bread, mix into grain bowls, or use as a marinade for proteins.
Storage
Store in refrigerator for up to 10 days with plastic wrap pressed against surface and thin oil layer on top. Freeze in ice cube trays for 6-month storage. The color will darken slightly but flavor remains excellent.
