How to Make Easy Butter Garlic Spaghetti Recipe
Step 1: Cook the Spaghetti
Start by bringing a large pot of salted water to a rolling boil. Cook the spaghetti according to the package instructions until just al dente—this ensures the pasta has a little bite that holds up beautifully to the luscious garlic butter sauce. Don’t forget to reserve 1/2 cup of the pasta cooking water before draining; that starchy liquid will be your secret weapon for loosening the sauce to just the right consistency.
Step 2: Prepare the Garlic Butter Sauce
While the pasta cooks, melt the unsalted butter in a large skillet over medium heat. Once melted, add the minced garlic and optional red pepper flakes. Cook for 1 to 2 minutes, stirring frequently, until the garlic is aromatic and just turning golden. This step is crucial because you want to coax the garlic’s flavor out without burning it, which would create bitterness.
Step 3: Toss the Pasta in the Sauce
Transfer the cooked spaghetti directly into the skillet with your garlic butter sauce. Toss to ensure every strand is coated with that glossy, fragrant mixture. If the sauce feels too thick, add the reserved pasta water a little at a time to loosen it. This technique helps the sauce cling perfectly to the pasta and creates a silky, luscious coating.
Step 4: Season and Add Fresh Parsley
Now it’s time to season your dish. Sprinkle salt and freshly ground black pepper to taste, then fold in the chopped fresh parsley. The parsley adds brightness and a fresh green contrast that elevates the overall appearance and taste of this simple pasta delight.
Step 5: Serve Immediately with a Parmesan Finish
Plate your spaghetti while it’s warm and top generously with grated Parmesan cheese. The salty, nutty cheese melts into the warm pasta, completing the dish with a perfect finishing touch that keeps you coming back for more.

Side Dishes
This dish pairs wonderfully with a crisp green salad dressed with lemon vinaigrette, adding a refreshing balance to the richness. Garlic bread or a crusty baguette is also a perfect side, perfect for soaking up any leftover buttery garlic sauce. For a heartier meal, a simple roasted vegetable medley or grilled chicken breast complements the pasta beautifully.

Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers (though probably rare!), transfer the pasta into an airtight container and refrigerate. It will stay fresh for up to 3 days, maintaining most of its buttery, garlicky goodness.
Freezing
While freezing butter garlic spaghetti is possible, it’s not ideal as the texture of the pasta might change upon thawing. If you do freeze it, store it in a freezer-safe container for up to 2 months and expect to use it in baked dishes or casseroles rather than reheating straight.
Reheating
When ready to enjoy, gently reheat the spaghetti in a skillet over low heat, adding a splash of water or broth to revive the sauce’s silky texture. Avoid microwaving without moisture as it can dry out the pasta and sauce.
FAQs
Can I use a different type of pasta in the Easy Butter Garlic Spaghetti Recipe?
Absolutely! While spaghetti is classic, you can substitute with linguine, fettuccine, or even penne. Just keep cooking times in mind and adjust accordingly to ensure your pasta stays perfectly al dente.
Is the red pepper flakes ingredient necessary?
Not at all! Red pepper flakes add a gentle heat that balances the richness but are completely optional. Feel free to leave them out or adjust the amount based on your spice preference.
Can I make this recipe vegan?
Yes! Replace the butter with a plant-based margarine or olive oil, and use a vegan Parmesan alternative or nutritional yeast to keep the cheesy flavor without any animal products.
How do I make sure the garlic doesn’t burn?
Cook the garlic on medium to medium-low heat, stirring frequently. As soon as it turns golden and releases its aroma, remove from heat to prevent bitterness caused by burning.
What’s the purpose of reserved pasta water?
The reserved pasta water contains starch released during cooking which helps loosen and bind the sauce to the pasta, making it silky and cohesive rather than dry or clumpy.
