Start by preparing your ingredients. Rinse the broccoli florets thoroughly under cold water. Make sure they’re clean, as you want the freshest flavors in your pesto. Cut them into smaller pieces to fit into your food processor easily.
If you're using parsley, give it a quick rinse too. You can also substitute it with basil if you prefer a different flavor profile. Once cleaned, roughly chop the leaves to help them blend more smoothly.
Now it’s time to assemble everything in your food processor. Add the cleaned broccoli and parsley (or basil if using) to the food processor bowl. You want to start with these two as they form the base of your pesto.
Next, add the rest of your ingredients: lemon zest, lemon juice (if using), olive oil, Parmesan cheese, and sunflower seeds. This combination is where all the magic happens!
Secure the lid on your food processor and pulse the mixture a few times to start breaking down the ingredients. You want to mix it until it starts to combine but not completely smooth just yet.
After the initial pulses, scrape down the sides of the bowl with a spatula. This ensures everything is getting blended evenly. It’s crucial to stop and scrape down a few times to achieve that perfect pesto consistency.
Continue blending the mixture until you achieve a uniform paste, which may take about 60 to 90 seconds. If it looks too thick, you can add a bit more olive oil to help it blend better. You want it creamy but still have some texture.
Once blended, taste your pesto and season it with salt to your liking. I often find that I don’t need much, but it’s all about personal preference!
To serve with pasta, prepare your favorite pasta according to the package directions. Start by tossing about ½ cup of the pesto with the cooked pasta and add more if needed to coat it well. It’s a great way to enjoy this vibrant sauce!
If you’re looking to use it as pizza sauce, spread about ½ cup of the pesto over your raw pizza dough. It gives a delightful twist to your usual pizza. Store any leftover pesto in an airtight container in the fridge for up to 5 days. You can also freeze it in a bag for up to 6 months!
