Ingredients You’ll Need (Serves 6)

Here’s what you’ll need to create this luscious lemon butter pasta sauce:

Basic Ingredients:

• 1 pound (450g) spaghetti or fettuccine (or pasta of choice)
• 6 tablespoons unsalted butter
• Zest of 1 large lemon
• Juice of 2 large lemons (about 5–6 tablespoons)
• 3 cloves garlic, finely minced
• Salt and black pepper to taste

Optional Flavor Boosters:

• ¼ cup grated Parmesan cheese (optional, for richness)
• 1 teaspoon crushed red pepper flakes (for a gentle heat)
• 2 tablespoons chopped fresh parsley or basil (for garnish)
• 1–2 tablespoons reserved pasta water (for emulsifying the sauce)

The Perfect Pasta Pairing

This lemon butter pasta sauce works beautifully with a variety of pasta types:

• Spaghetti: The classic go-to; lets the sauce shine.
• Fettuccine or Tagliatelle: Great for a more decadent, silky finish.
• Angel Hair: Light and delicate, ideal for summer meals.
• Penne or Fusilli: Good choices if you want the sauce to tuck into crevices.

Step-by-Step Instructions

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Cook the pasta until al dente according to package instructions. Reserve about 1 cup of pasta water, then drain and set aside.

Step 2: Sauté the Garlic

In a large skillet over medium heat, melt 6 tablespoons of butter. Once it starts to foam, add the minced garlic and sauté for about 1 minute until fragrant. Don’t let it brown.

Step 3: Add Lemon

Add the lemon zest and lemon juice to the skillet. Stir gently to combine with the butter and garlic. Let it simmer for 1–2 minutes to marry the flavors.

Step 4: Emulsify the Sauce

Add a tablespoon or two of reserved pasta water to the pan and stir. This helps emulsify the sauce so it clings to the pasta. Season with salt and black pepper to taste.

Step 5: Toss the Pasta

Add the drained pasta directly into the skillet. Toss everything together over low heat until the noodles are coated with the glossy sauce.

Step 6: Finish and Serve

(Optional) Stir in Parmesan cheese and red pepper flakes for added flavor. Serve hot, garnished with parsley or basil, and an extra twist of lemon zest if desired.

Chef Tips for Success

• Use fresh lemons. Bottled juice won’t give you the same vibrant citrus flavor.
• Don’t skip the zest! It adds that aromatic lemony kick.
• Adjust the butter-to-lemon ratio if you like it more buttery or more tart.
• Pasta water is your friend. It helps create a silky texture without cream.

Variations to Try

This lemon butter pasta sauce is wonderfully flexible. Here are a few variations:

1. Lemon Garlic Shrimp Pasta

Add sautéed shrimp in the last minute of cooking for a quick seafood upgrade.

2. Creamy Lemon Butter Sauce

Stir in ¼ cup of heavy cream and Parmesan cheese for a richer, Alfredo-like twist.

3. Lemon Butter Chicken Pasta

Toss with grilled or roasted chicken for a hearty, protein-packed meal.

4. Vegan Version

Swap the butter for vegan butter and skip the cheese. Add nutritional yeast for a nutty, cheesy note.

What to Serve With Lemon Butter Pasta

This dish is delicious on its own but also shines when served with:

• Grilled asparagus or green beans
• Arugula salad with lemon vinaigrette
• Garlic bread or sourdough toast
• A crisp white wine like Pinot Grigio or Sauvignon Blanc

Why Lemon Butter Sauce Works for Every Season

Summer:

Lemon gives this sauce a bright, citrusy profile that pairs well with lighter meals, grilled vegetables, or chilled white wines. Serve it with fresh herbs for an outdoor lunch or dinner.

Winter:

The butter base brings cozy warmth, while the lemon cuts through richness. Perfect for when you want comfort food that doesn’t feel too heavy.

Make Ahead and Storage Tips

• Make Ahead: You can prep the sauce (without the pasta) a few hours ahead and reheat gently.
• Storage: Store leftovers in an airtight container for up to 3 days.
• Reheating: Warm over low heat with a splash of water or broth to loosen the sauce.

Common Questions

Can I use bottled lemon juice?

Fresh is best. Bottled lemon juice can taste flat or sour and lacks the aromatic oils of fresh zest.

Can I make it gluten-free?

Absolutely! Just use your favorite gluten-free pasta.

What if I don’t have Parmesan?

The sauce is delicious without it. But you can add nutritional yeast or Pecorino as a substitute.
