Key Ingredients

The main ingredients for our Perfect Linguine with Creamy Arugula Walnut Pesto include linguine pasta, fresh arugula, walnuts, garlic, parmesan cheese, olive oil, salt, and pepper. For the pesto, you’ll also need grated parmesan and a squeeze of lemon juice. Practical substitutions can be made for some ingredients – for example, using pine nuts instead of walnuts or spinach instead of arugula, though the flavor and texture might slightly differ. Having high-quality ingredients, especially the freshness of the arugula and the quality of the parmesan, will significantly impact the final taste of your dish.

Instructions

1. Step 1: Begin by preparing your ingredients. Rinse the arugula and pat it dry, peel the garlic, and grate the parmesan cheese. Measure out the walnuts and olive oil. Bring a large pot of salted water to a boil for the linguine.
2. Step 2: Cook the linguine according to the package instructions until it’s al dente. Reserve a cup of pasta water before draining the linguine. This water can be used later to thin out the pesto if needed.
3. Step 3: Make the creamy arugula walnut pesto. In a food processor, combine the arugula, walnuts, garlic, parmesan cheese, salt, and pepper. Process until the mixture is well combined and slightly smooth. With the processor running, slowly pour in the olive oil through the top. Add a squeeze of lemon juice to taste. If the pesto seems too thick, add a bit of the reserved pasta water.
4. Step 4: Combine the cooked linguine and the pesto sauce. Toss everything together until the pasta is well coated. If the sauce seems too thick, add a bit more pasta water. Season with additional salt, pepper, or lemon juice if needed. Serve immediately, topped with additional parmesan cheese and any desired toppings such as cherry tomatoes or toasted walnuts.

Handy Tips

• To avoid over-processing the pesto, which can make it too smooth and lose its texture, stop the food processor occasionally and scrape down the sides with a spatula.
• For an extra creamy pesto, you can add a tablespoon or two of plain Greek yogurt or sour cream towards the end of processing.
• Always taste as you go and adjust the seasoning. The pesto can be quite strong, so it’s better to add ingredients gradually and taste frequently.

Heat Control

When cooking the linguine, it’s crucial to control the heat to achieve the perfect al dente texture. Start with high heat to bring the water to a boil, then reduce the heat to a simmer once the linguine is added. The ideal temperature for cooking pasta is between 195°F and 205°F. Cooking time will vary based on the type of linguine, but generally, it takes between 8 to 12 minutes. The pasta is done when it still has a bit of bite or chew to it. Overcooking can result in a mushy, unappetizing texture.

Crunch Factor

The crunch factor in this dish comes from the walnuts in the pesto and any optional crunchy toppings like toasted walnuts or cherry tomatoes. To achieve the perfect crunch, ensure that your walnuts are fresh and not rancid. If using toasted walnuts for topping, toast them lightly in a pan over medium heat, stirring frequently, until they are fragrant and slightly browned. This adds depth and texture to the dish. The arugula also provides a peppery freshness that complements the crunch of the walnuts beautifully.

Pro Kitchen Tricks

• For a more vibrant pesto, add a handful of ice cubes to the food processor along with the arugula. The cold temperature helps preserve the green color of the arugula.
• Use a high-quality extra virgin olive oil for the best flavor in your pesto.
• To prevent the pesto from oxidizing and turning brown, press plastic wrap directly onto the surface of the pesto if you’re not using it immediately.

Storage Tips

• The creamy arugula walnut pesto can be stored in an airtight container in the refrigerator for up to a week. Give it a good stir before using.
• Cooked linguine can be stored in the fridge for up to 3 days. Reheat it by tossing it in a pan with a bit of olive oil or by microwaving it with a splash of water.
• For longer storage, the pesto can be frozen for up to 6 months. Simply thaw it overnight in the fridge when you’re ready to use it.

Gift Packaging Ideas

If you’re considering gifting this dish, a beautiful way to present it is by filling a decorative jar with the creamy arugula walnut pesto, topping it with a layer of olive oil to preserve it, and including a packet of linguine and a wedge of parmesan cheese on the side. Wrap the jar in a ribbon and include a recipe card with instructions on how to prepare the linguine and combine it with the pesto. This makes for a thoughtful and unique gift for any food lover.

Flavor Variations

• Different spices: Consider adding a pinch of red pepper flakes for a spicy kick or some dried basil for an Italian twist.
• Creative toppings: In addition to cherry tomatoes and toasted walnuts, other toppings could include grilled chicken, roasted vegetables, or sautéed mushrooms.
• Ingredient swaps: Instead of walnuts, you could use almonds or pistachios for a different flavor profile. Spinach or kale could be used in place of arugula for a milder taste.

Troubleshooting

• Texture problems: If your pesto turns out too thick, add a bit of pasta water or olive oil. If it’s too thin, add more arugula or parmesan cheese.
• Ingredient replacements: If you can’t find arugula, spinach or kale can be used as substitutes, though the flavor will be milder.
• Over/undercooking signs: Check your linguine frequently during the last few minutes of cooking. It should have a bit of bite to it. If it’s mushy, it’s overcooked. If it’s too hard, it’s undercooked.

FAQs

• Can I freeze it? Yes, the pesto can be frozen for up to 6 months. Simply thaw it overnight in the fridge when you’re ready to use it.
• Is it gluten-free? The pesto itself is gluten-free, but the linguine is not. You can substitute the linguine with gluten-free pasta to make the dish gluten-free.
• Can I double the recipe? Yes, you can easily double or triple the recipe for a larger crowd. Just be sure to adjust the cooking time of the linguine accordingly and use a larger food processor for the pesto.
