Ingredient Rundown
- 12 ounces dry pasta (I used gemelli, but any pasta shape will work wonderfully)
- 4 cups arugula (packed, I used baby arugula for a milder flavor)
- ¾ cup olive oil (a good quality extra virgin olive oil enhances the flavor)
- 3 cloves garlic (peeled and ready to go)
- ¾ cup walnuts (toasted for added depth of flavor)
- ¾ cup Parmesan cheese (grated, for that rich umami kick)
- 1 teaspoon salt (or to taste)
- ½ teaspoon pepper (or to taste)
Before You Start: Equipment
- Large pot (for boiling pasta)
- Food processor (to make the pesto smooth and creamy)
- Measuring cups and spoons (for accurate ingredient amounts)
- Colander (to drain the pasta)
- Large mixing bowl (to combine pasta and pesto)
Arugula Walnut Pesto Pasta Made Stepwise

Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a boil. Add the 12 ounces of dry pasta and cook according to package instructions until al dente. Reserve about ½ cup of the pasta cooking water before draining the pasta.
Step 2: Prepare the Pesto
While the pasta is cooking, grab your food processor. Add the 4 cups of packed arugula, ¾ cup of walnuts, 3 cloves of garlic, ¾ cup of grated Parmesan cheese, 1 teaspoon of salt, and ½ teaspoon of pepper. Pulse the ingredients until they are coarsely chopped.
Step 3: Add Olive Oil
With the food processor running, slowly drizzle in the ¾ cup of olive oil until the pesto reaches a smooth and creamy consistency. You might need to scrape down the sides to ensure everything is well combined.
Step 4: Combine Pasta and Pesto
In a large mixing bowl, toss the drained pasta with the pesto. If the mixture seems too thick, add a little of the reserved pasta cooking water until you achieve your desired consistency.
Step 5: Serve
Serve the Arugula Walnut Pesto Pasta warm, garnished with extra grated Parmesan cheese and a sprinkle of freshly ground black pepper. Enjoy this delicious dish with your favorite side salad or crusty bread.
Swap Guide

- Pasta: Feel free to use gluten-free pasta or whole wheat pasta for a healthier option.
- Cheese: For a dairy-free alternative, try nutritional yeast or a vegan Parmesan substitute.
- Walnuts: If you’re not a fan of walnuts, pine nuts or almonds work beautifully in pesto.
- Garlic: To mellow the garlic flavor, use roasted garlic instead of raw.
Notes on Ingredients
The freshness of your ingredients is key to making a vibrant Arugula Walnut Pesto Pasta. Opt for freshly grated Parmesan cheese instead of pre-grated for a creamier texture and better flavor. If you’re using regular arugula instead of baby arugula, you might want to adjust the amount as the flavor will be stronger.
Leftovers & Meal Prep
This Arugula Walnut Pesto Pasta makes great leftovers! Store any uneaten pasta in an airtight container in the refrigerator for up to 3 days. When reheating, you might need to add a splash of olive oil or reserved pasta water to bring it back to life. If you plan to meal prep, consider keeping the pesto separate from the pasta to prevent it from getting soggy.
