→ For the Pasta & Base

• Pasta: 1 pound of an uncooked short pasta. I love how a shape like Mezze Rigatoni or fusilli grabs onto the pesto.
• Broccoli Florets: 2 1/2 cups. These will be the delicious, secret base of our green sauce.

→ For the Lemony Broccoli Pesto

• Fresh Basil Leaves: 1 tightly packed cup. An essential, aromatic component of any great pesto.
• Parmesan Cheese: 1 cup, freshly-grated. For that salty, nutty, umami flavor that brings everything together.
• Pine Nuts or Slivered Almonds: 1/3 cup, toasted. Toasting them first is a quick step that makes a huge difference in flavor!
• Fresh Baby Spinach: A large handful, to add even more vibrant green color and nutrients.
• Garlic: 2 large cloves.
• Lemon: 1 large one. We’ll use both the zest and the juice for maximum bright, citrusy flavor.
• Extra-Virgin Olive Oil: 1/2 cup. Use a good quality one for the best taste.
• Salt & Pepper: To season everything perfectly.

Let’s Cook! Your Guide to a Perfect 30-Minute Dinner

The beauty of this recipe is its efficiency. The pesto comes together entirely in the time it takes for the pasta to cook. Let’s get started!

Phase 1: Cook the Pasta and Broccoli (Time: ~15 minutes)

This first step is a brilliant two-for-one, cooking our veggies and pasta in the same pot!

1. Boil the Water. Bring a large stockpot of generously-salted water to a rolling boil over high heat.
2. Blanch the Broccoli. Add the broccoli florets to the boiling water and cook for just 3 minutes, until they are bright green and tender-crisp. Use a spider strainer or a large slotted spoon to transfer the broccoli directly to the bowl of a food processor. Leave the water boiling in the pot.
3. Cook the Pasta. Add your pasta to the same pot of boiling water and cook according to the package directions until it is just al dente (still has a slight bite).

Phase 2: Create the Vibrant Pesto (Time: ~5 minutes)

While the pasta cooks, we’ll transform our blanched broccoli into a luscious, creamy pesto.

4. Combine Pesto Ingredients. To the food processor with the hot broccoli, add the basil, Parmesan, toasted pine nuts, spinach, garlic, lemon zest, lemon juice, salt, and pepper.
5. Blend Until Smooth. Pulse the mixture a few times to break it down. Then, with the processor running, slowly drizzle in the olive oil until the mixture is mostly smooth.
6. The Secret Ingredient! Just before your pasta is done cooking, carefully scoop out about 1/4 cup of the starchy, boiling pasta water. Add this directly to the food processor and pulse again until the pesto is super-smooth and creamy.

Phase 3: The Final Toss (Time: ~2 minutes)

Now we bring everything together for the grand finale!

7. Reserve More Pasta Water. Before you drain the pasta, scoop out another 1/2 cup of the starchy pasta water and set it aside. This is your insurance for a perfect sauce!
8. Drain and Toss. Drain the pasta and immediately return it to the hot stockpot. Pour the broccoli pesto over the top and use tongs to toss everything together until every piece of pasta is coated in the vibrant green sauce.
9. Adjust and Serve. If the pesto seems too thick or dry, add a splash of your reserved starchy water and toss again until it reaches a perfect, luscious consistency. Serve warm, garnished with extra Parmesan cheese and a final twist of black pepper.

WiseRecipes’ Top Tips for Perfect Pesto Pasta!

• Don’t Overcook the Broccoli: A quick 3-minute blanch is all it needs. This keeps it bright green and full of nutrients. Overcooking will result in a dull, olive-colored pesto.
• Starchy Pasta Water is Liquid Gold: This is the number one secret to amazing pasta sauces. The starch in the water helps the sauce emulsify and cling to the pasta, creating a creamy texture without any actual cream. Always save more than you think you’ll need!
• Toast Your Nuts: It’s a small step that makes a huge difference! Toasting your pine nuts or almonds in a dry skillet for a few minutes until fragrant brings out their nutty, complex flavor.
• Zest Your Lemon First: Always zest your lemon before you juice it. It’s much easier! The zest contains all the aromatic oils and provides an incredible burst of lemon flavor.
• Serve Immediately: This pesto is at its most vibrant and delicious when served fresh and hot. The colors will be at their peak!

Creative Twists: Delicious Ways to Customize Your Pasta!

• Add a Protein: This dish is a perfect base for adding some protein. Toss in some cooked, shredded chicken, sautéed shrimp, or a can of rinsed white beans.
• Make it Spicy: Add a generous pinch of red pepper flakes to the pesto in the food processor for a little bit of warmth.
• Add More Veggies: Stir in a cup of green peas (you can cook them with the pasta) or some sautéed asparagus tips at the end.
• Make it Vegan: For a delicious vegan version, use nutritional yeast in place of the Parmesan and ensure you have no other non-vegan ingredients.
• Get Nutty: If you don’t have pine nuts, toasted walnuts, pistachios, or even sunflower seeds are fantastic substitutes.
• For an Extra Creamy Kick: While the pasta water does a great job, you can make this extra decadent by stirring in a few tablespoons of heavy cream, crème fraîche, or cream cheese at the very end.

Method

 

Cook Broccoli and Pasta

1. Bring a large stockpot of generously-salted water to a boil. Add the broccoli and cook for 3 minutes until tender-crisp. Use a slotted spoon to transfer the broccoli to a food processor, leaving the water boiling.
2. Add the pasta to the same stockpot and cook according to package directions until just al dente.

3. Serve warm, garnished with extra Parmesan and a twist of black pepper.

Notes

Pasta Water is Magic: The starchy pasta water is the secret ingredient that helps the pesto emulsify and become a creamy sauce that clings to the noodles without any heavy cream.

Don’t Overcook Broccoli: A quick 3-minute blanch is all the broccoli needs to become tender-crisp and maintain its vibrant green color.

Nut-Free Option: For a nut-free version, simply substitute the pine nuts with toasted sunflower seeds or pepitas.

Make Ahead: The pesto can be made a day in advance. Store it in an airtight container with plastic wrap pressed against the surface to prevent browning. You may need a little extra pasta water to loosen it up when tossing with the hot pasta.

Keep it Fresh! Storing Your Leftover Pesto Pasta

While this pasta is at its absolute best when served fresh, leftovers still make for a delicious and easy lunch!

Refrigerator Storage

Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. Be aware that the pesto may darken slightly in color as it oxidizes, but it will still be delicious.

Reheating

Gently reheat the pasta in a skillet over medium-low heat. Add a splash of water or broth to help loosen up the pesto and bring back its saucy consistency. You can also reheat it in the microwave.

FAQs: Your Lemony Pesto Pasta Questions, Answered!

Can I use frozen broccoli for this recipe?

Yes, absolutely. You can add the frozen broccoli florets directly to the boiling pasta water. They may only need 2-3 minutes to become tender-crisp since they have been blanched already.

How do I make this recipe nut-free?

Easily! For a nut-free version, simply substitute the pine nuts or almonds with toasted sunflower seeds or pepitas (pumpkin seeds). They will provide a similar rich, toasty flavor and texture.

Why isn’t my pesto as bright green?

The most common culprit for a dull-colored pesto is overcooking the broccoli. A quick 3-minute blanch is all it takes to cook it through while keeping it vibrant. Using very fresh basil and spinach also helps maintain a beautiful color.

Can I make the pesto ahead of time?

You can! You can make the pesto and store it in an airtight container in the fridge for up to 2 days. To prevent it from browning, press a piece of plastic wrap directly onto the surface of the pesto before sealing the container. You’ll just need to cook your pasta and reserve some fresh pasta water to thin out the cold pesto when you toss it all together.

This Lemony Broccoli Pesto Pasta is a true weeknight champion.
