Ingredients for Spaghetti with Lemon Garlic Butter Sauce

Here’s the beautiful part – you only need a handful of simple ingredients to make magic happen. I’ve learned through trial and error (and one disastrous “lemony” incident) that quality really matters here:

• 8 oz spaghetti – The dry weight measurement is key here; I grab my kitchen scale for accuracy
• 3 tbsp butter – Unsalted is my go-to so I can control the saltiness (and it browns beautifully)
• 3 garlic cloves, minced – Don’t you dare use that pre-minced stuff. Fresh makes all the difference
• 1 lemon – We’re using both the zest and juice for maximum citrus punch
• 1/4 cup grated parmesan – Freshly grated melts so much better than the pre-shredded kind
• 1/4 tsp each salt & black pepper – Start here, then adjust to taste
• 2 tbsp chopped parsley – Fresh herbs brighten everything up

See? Nothing fancy – just good ingredients treated right. Now let’s make some magic.

How to Make Spaghetti with Lemon Garlic Butter Sauce

Okay, let’s get cooking. This comes together so fast you’ll want everything prepped and ready to go. I’ve burned more than my share of garlic rushing around the kitchen, so learn from my mistakes – mise en place is your friend here.

Cook the Pasta

First things first – get that pasta water boiling. I use a big pot with plenty of salted water (it should taste like the sea). Toss in your 8 oz of spaghetti and cook it about 1 minute less than the package says – we want that perfect al dente bite. Here’s my pro tip: before draining, scoop out about 1/2 cup of that starchy pasta water. Trust me, it’ll be our secret weapon for adjusting the sauce later.

Prepare the Lemon Garlic Butter Sauce

While the pasta cooks, let’s make that magical sauce. Melt 3 tbsp butter in a large skillet over medium heat – you’ll know it’s ready when those little bubbles subside. Add your minced garlic and stir constantly for just about 30 seconds to 1 minute. We’re looking for fragrant and golden, not brown and bitter. Then zest your lemon right into the pan (about 1 tbsp) and squeeze in the juice (about 2 tbsp). The smell at this point? Absolute heaven.

Combine and Serve

Now for the best part – bring it all together. Add your drained spaghetti straight to the skillet and toss like your life depends on it. If the sauce seems too thick, splash in some of that reserved pasta water a tablespoon at a time. Sprinkle in the parmesan, give it another good toss, then taste and adjust with salt and pepper. Finish with a shower of chopped parsley for that fresh pop of color. Serve immediately while it’s still piping hot – this is one dish that doesn’t wait.

Tips for Perfect Spaghetti with Lemon Garlic Butter Sauce

After making this dish more times than I can count (and learning from some delicious mistakes), here are my can’t-miss tips for spaghetti that’ll have everyone asking for seconds:

• Fresh is best – That bottled lemon juice just doesn’t compare to the bright zing of fresh. Roll your lemon on the counter first to get every last drop.
• Watch that garlic – It goes from golden to bitter in seconds. Keep stirring and pull it off the heat the moment it becomes fragrant.
• Pasta water is magic – Start with 1/4 cup when combining, then add more as needed. That starchy liquid makes the sauce cling perfectly.
• Make it yours – A pinch of red pepper flakes adds heat, extra herbs bring freshness, or a handful of spinach makes it feel fancier.

Remember – great cooking is about tasting as you go. Love it lemony? Add more zest. Want it richer? Extra parmesan never hurt anyone.

Variations for Spaghetti with Lemon Garlic Butter Sauce

One of my favorite things about this recipe? It’s like a blank canvas waiting for your personal touch. Here are the variations I turn to most often when we want to mix things up:

• Garlic butter shrimp – Sauté a handful of shrimp in the butter before adding garlic for a protein-packed upgrade
• Roasted cherry tomatoes – Toss a pint with olive oil and roast while the pasta cooks, then fold them in at the end
• Baby spinach power move – Throw in a few handfuls right after draining the pasta – the residual heat wilts it perfectly

Sometimes I’ll even swap the parsley for fresh basil when summer rolls around – the possibilities are endless.

Serving Suggestions

This spaghetti shines brightest when paired with simple sides that don’t compete with its bright flavors. My family loves it with a crisp arugula salad (just greens, lemon vinaigrette, and shaved parmesan) – the peppery bite balances the rich pasta perfectly. For heartier appetites, I’ll throw together some quick garlic bread – just toast slices rubbed with garlic and brushed with olive oil. In summer, I often serve it alongside grilled zucchini or asparagus. The rule? Keep it fresh, keep it simple, and let that lemony pasta be the star.

Storage & Reheating

Here’s the good news – any leftovers (if you’re lucky enough to have them) keep beautifully. Just transfer to an airtight container and stash in the fridge for up to 3 days. When reheating, add a splash of water and warm gently over low heat, stirring often. The water helps bring that silky sauce back to life – I like to pretend it’s whispering “hello again” to my tastebuds.

Nutritional Information

Now, I’m no nutritionist, but here’s the scoop on what you’re getting in each satisfying bowl of this lemony goodness. These numbers are estimates (let’s be real – my Parmesan pours are never exactly measured), but per serving you’re looking at about 450 calories, 18g fat, 60g carbs, and 12g protein. The fresh ingredients make it feel light, while that glorious butter and pasta keep it comforting. Not bad for something that tastes this indulgent, right? Just don’t ask me to do the math after seconds.
