Ingredient Notes & Substitutions

Spinach

Fresh baby spinach gives the sauce its bright green color and mild flavor. Frozen spinach can work, but thaw and squeeze it very well before blending.

Spaghetti

Spaghetti is perfect for this sauce because the creamy green mixture coats every strand. Linguine, fettuccine, or bucatini can also be used.

Parmesan

Freshly grated Parmesan gives the sauce a savory, nutty flavor and a smoother texture.

Heavy Cream

Heavy cream makes the sauce richer and creamier. For a lighter version, use half-and-half.

Lemon Juice

Fresh lemon juice adds brightness and balances the richness of the Parmesan and cream.

Olive Oil

Use a good-quality extra-virgin olive oil for the best flavor because it is part of the sauce.

Equipment You’ll Need

• Large pot
• Colander

How to Make Green Spaghetti Pasta

Step 1: Cook the Spaghetti

Bring a large pot of generously salted water to a boil.

Add the spaghetti and cook according to the package directions until al dente.

Before draining, reserve ½ cup of pasta water.

Drain the spaghetti and set aside.

Step 2: Prepare the Green Sauce

Add the following ingredients to a blender:

• Fresh baby spinach
• Garlic
• Parmesan cheese
• Olive oil
• Heavy cream
• Lemon juice
• Black pepper
• Salt

Blend until completely smooth and creamy.

If the sauce is too thick, add a tablespoon or two of the reserved pasta water and blend again.

Step 3: Warm the Sauce

Heat a large skillet over low heat.

Pour the blended green sauce into the skillet.

Warm gently for about 2 minutes, stirring occasionally.

Don’t let the sauce boil, as high heat can cause the Parmesan and cream to separate.

Step 4: Add the Spaghetti

Add the cooked spaghetti directly to the skillet.

Use tongs to gently toss the pasta with the green sauce.

Add reserved pasta water a little at a time until the sauce coats the spaghetti beautifully.

Step 5: Adjust the Flavor

Taste the pasta and adjust the seasoning.

Add more Parmesan for a richer flavor, lemon juice for brightness, or red pepper flakes for a little heat.

Step 6: Garnish

Transfer the pasta to serving bowls.

Top with:

• Freshly grated Parmesan
• Fresh basil
• Lemon zest
• Cracked black pepper

Step 7: Serve

Serve the Green Spaghetti Pasta immediately while warm and creamy.

For a complete dinner, pair it with garlic bread, a simple salad, or grilled chicken.

Expert Tips

Use fresh baby spinach for the brightest green color and mildest flavor.

Don’t boil the green sauce. Gentle heat keeps the sauce smooth and vibrant.

Reserve pasta water. The starch helps loosen the sauce and makes it cling beautifully to the spaghetti.

Blend until completely smooth. A smooth sauce creates the best creamy texture.

Add lemon at the end. Fresh lemon juice brightens the spinach and Parmesan flavors.

Use freshly grated Parmesan. It melts more easily and gives the sauce better flavor.

Serve immediately. The sauce naturally thickens as it sits.

Storage & Reheating

Store leftover Green Spaghetti Pasta in an airtight container in the refrigerator for up to 3 days.

Stir gently until warmed through and creamy again.

You can also microwave individual portions in 30-second intervals, stirring between each interval.

For the best texture and color, freezing is not recommended.

• Forgetting to reserve pasta water.
