Step‑by‑Step Instructions for Homemade Skinny Basil Pesto
Step 1: Prepare Ingredients
Begin by washing 2 cups of packed fresh basil leaves under cool water, then gently pat them dry with a clean towel. Peel and chop 2-3 cloves of garlic, ensuring no large pieces remain. Make sure your food processor is ready as we’ll use it to blend these vibrant ingredients into a smooth sauce.
Step 2: Blend Basil and Cheese
In your food processor, combine the fresh basil leaves, ½ cup of grated Pecorino Romano cheese, and the chopped garlic. Pulse the mixture until it’s coarsely chopped, about 10-15 seconds. Scrape down the sides with a spatula as needed to ensure every bit of basil is incorporated into our Homemade Skinny Basil Pesto base.
Step 3: Add Olive Oil
With the food processor running on low, slowly drizzle in up to ⅓ cup of extra virgin olive oil. Keep blending until the mixture becomes a smooth and creamy consistency, which should take about 20-30 seconds. You may need to adjust the oil to reach your desired thickness—if it’s too thick, feel free to add a touch more oil!
Step 4: Season to Taste
Once the pesto reaches a silky smooth texture, add salt and freshly cracked black pepper to taste. Start with a pinch of salt and a few turns of the grinder, blending again for about 5 seconds. Taste and adjust the seasoning as needed, ensuring the bold flavors of your Homemade Skinny Basil Pesto shine through.
Step 5: Store or Serve
Transfer your vibrant pesto into a clean, airtight container. If you plan to use it later, drizzle a thin layer of olive oil on top to keep it fresh. This nut-free basil pesto can be stored in the refrigerator for 3-4 days or frozen in small portions for up to 3 months, perfect for adding flavor to future meals.
