- 8 oz spaghetti: Choose your favorite brand; al dente texture is key for that perfect bite.
- 4 tablespoons unsalted butter: Provides the rich, creamy base for the sauce without overpowering garlic’s subtlety.
- 4 cloves garlic, minced: The star player, infusing the dish with that signature vibrant aroma and taste.
- 1/4 teaspoon red pepper flakes (optional): Adds a gentle heat that lifts the whole dish without stealing the spotlight.
- Salt and freshly ground black pepper, to taste: Essential seasonings that enhance all the flavors naturally.
- 2 tablespoons chopped fresh parsley: Brings a fresh, green brightness and color contrast that’s as pleasing to the eye as to the palate.
- Grated Parmesan cheese, for serving: Adds a savory, nutty depth and creamy finish to every forkful.
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—this seasoning step is crucial to flavoring the pasta from the inside out. Cook the spaghetti exactly according to package instructions for al dente perfection. Before draining, scoop out about half a cup of the starchy pasta water; this golden liquid will help loosen and blend the sauce beautifully later.
Step 2: Prepare the Garlic Butter Sauce
Next, melt the butter in a spacious skillet set over medium heat. Add in your minced garlic and the red pepper flakes if using, and gently sauté just until the garlic is fragrant and turns a lovely light golden shade — be careful not to burn it because burnt garlic tastes bitter. This step brings that irresistible aroma to your kitchen and lays the saucy foundation for the dish.
Step 3: Toss the Pasta
Add the drained spaghetti directly into the bubbling garlic butter sauce. Toss well to coat every strand in that luscious, garlicky butter. If the sauce feels too thick or the pasta looks dry, gradually add a splash of the reserved pasta water, stirring and loosening until everything melds into a glossy, silky coating.
Step 4: Season and Add Fresh Herbs
Now it’s time to elevate the flavor—season with salt and freshly ground black pepper to your liking. Gently fold in the chopped fresh parsley, which instantly brightens the dish and adds a fresh aroma that balances the richness perfectly.
Step 5: Serve Immediately
Plate your masterpiece right away, topping each serving generously with grated Parmesan cheese. The cheese melts slightly over the warm pasta, adding a nutty, salty finish that makes every bite pure comfort.
How to Serve Easy Butter Garlic Spaghetti Recipe

Garnishes
Beyond the classic grated Parmesan and parsley, try adding a little lemon zest or a drizzle of extra virgin olive oil for a citrusy brightness or silky richness. Toasted breadcrumbs sprinkled on top bring a crunchy contrast that adds an exciting texture dimension.
Side Dishes
This Easy Butter Garlic Spaghetti Recipe pairs wonderfully with a crisp green salad tossed with a simple vinaigrette, or some roasted vegetables like asparagus or cherry tomatoes to bring freshness and color to your plate. A warm, crusty bread is perfect for soaking up every last bit of garlic butter sauce.
Creative Ways to Present
For a cozy dinner party vibe, serve spaghetti twirled neatly on the plate with a sprig of fresh parsley and a Parmesan wedge on the side. Alternatively, layering the pasta in a shallow bowl with a shower of herbs and pepper flakes gives it a rustic, inviting look. Drizzle a little chili oil for a stunning visual and extra zing.
Make Ahead and Storage
Storing Leftovers
After enjoying your easy butter garlic spaghetti, any leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Be sure to cool the pasta completely before sealing to keep the texture and flavors fresh.
Freezing
While this recipe is best enjoyed fresh, you can freeze the cooked pasta (without the cheese garnish) by placing it in freezer-safe containers or bags. For up to one month, your easy butter garlic spaghetti will keep nicely, though the texture may soften slightly once thawed.
Reheating
To reheat, gently warm the spaghetti in a skillet over low heat with a splash of water or broth to revive the sauce. Avoid the microwave if possible, as it can dry out the noodles. Finish with a sprinkle of fresh Parmesan and parsley to refresh the flavors.
FAQs
Can I use a different type of pasta?
Absolutely! While spaghetti works beautifully with this garlic butter sauce, feel free to experiment with linguine, fettuccine, or even penne. Just adjust cooking times accordingly for the best texture.
How do I make this recipe vegan?
Swap the unsalted butter for a plant-based margarine or olive oil, and omit the Parmesan cheese or use a vegan cheese alternative. The garlic and red pepper flakes will still give plenty of flavor.
Can I add protein to this dish?
Yes! Grilled chicken, sautéed shrimp, or even crispy bacon bits make excellent additions, transforming it into a heartier main course without losing the essence of the easy butter garlic goodness.
Why is reserved pasta water important?
The starchy pasta water helps thin out and bind the butter and garlic sauce to the spaghetti, giving it a silky and cohesive texture rather than a clumpy one. It’s a secret tip from every great pasta cook.
How spicy is this dish with red pepper flakes?
The red pepper flakes add a gentle warmth and mild heat that enhances the garlic flavor without overwhelming the dish. You can always adjust the amount or leave them out altogether for a milder version.
