Ingredients You’ll Need

The ingredients for this creamy garlic butter spaghetti recipe work together to create a sauce that’s velvety, flavorful, and perfectly balanced. Investing in good quality Parmesan makes a noticeable difference, and fresh garlic is key to getting that buttery, aromatic punch.

• Spaghetti: I recommend using a good-quality durum wheat pasta for that perfect al dente bite.
• Olive Oil: Adds a subtle fruity undertone and helps sauté the onions and garlic evenly.
• Unsalted Butter: The star of the sauce—make sure it’s unsalted so you can control the seasoning better.
• Onion: Chopped finely to melt into the sauce and add a mild sweetness.
• Garlic: Fresh and minced, crucial for that signature garlicky flavor.
• Salt and Pepper: To taste, seasoning is everything here to bring all the flavors together.
• Italian Seasoning: A blend of herbs that brings warmth and complexity.
• White Wine (such as Sauvignon Blanc): If you don’t drink wine, a splash of broth works too—this adds depth without overpowering.
• Heavy Cream: The key to richness and that silky texture in the sauce.
• Parmesan Cheese: Freshly grated for the best melt and flavor impact.
• Red Pepper Flakes: Just a pinch to add a subtle kick—adjust to your heat preference.

Variations

One of the best things about this creamy garlic butter spaghetti recipe is how easily you can make it your own. I often tweak it depending on what I have on hand or the mood in the kitchen, and you should too—it’s all about enjoying the process and flavors.

• Protein Boost: I love adding cooked shrimp or grilled chicken for extra heartiness—it turns this dish into a full meal.
• Dairy-Free Version: Swap out the heavy cream for coconut milk and use vegan butter and Parmesan alternatives for a creamy, dairy-free twist.
• Veggie Upgrade: Toss in some sautéed mushrooms, spinach, or cherry tomatoes to add color and nutrition.
• Spicy Kick-Up: If you really like heat, sprinkle more red pepper flakes or even a dash of cayenne—I’m all about bold flavors.

How to Make Creamy Garlic Butter Spaghetti Recipe

Step 1: Perfectly Cook Your Spaghetti

Start by bringing a large pot of salted water to a boil and cook the spaghetti according to package instructions until al dente. I usually aim for just a minute less than the package suggests because the pasta will finish cooking in the sauce—this helps avoid mushiness and keeps the texture right where you want it.

Step 2: Build Your Flavor Base

While the pasta cooks, heat olive oil and butter in a large skillet over medium heat. Add the chopped onions and cook until translucent and soft, about 5 minutes. Then stir in the minced garlic and Italian seasoning, letting it cook gently for another minute—don’t let the garlic burn or it’ll get bitter, so keep an eye on the heat.

Step 3: Deglaze with White Wine

Pour in the white wine and let it simmer for 2-3 minutes to reduce slightly and concentrate the flavors. This step adds a beautiful brightness and balances the richness from the butter and cream. No wine at home? No worries, replace it with chicken or vegetable broth and you’re good to go.

Step 4: Create the Creamy Sauce

Reduce the heat to low and stir in the heavy cream, followed by salt, pepper, and red pepper flakes. Let the sauce gently bubble for a few minutes until it thickens slightly. Then sprinkle in the freshly grated Parmesan and stir until melted and smooth. This part always feels like magic because the sauce turns silky and luscious with every stir.

Step 5: Combine Spaghetti and Sauce

Drain the spaghetti (reserving a little pasta water just in case) and toss it into the skillet with your creamy sauce. Mix well to coat every strand. If the sauce feels too thick, add a splash of the reserved pasta water to loosen it up—it helps the sauce cling to the pasta beautifully!

How to Serve Creamy Garlic Butter Spaghetti Recipe

Garnishes

I like to top this creamy garlic butter spaghetti with a sprinkle of fresh chopped parsley for color and a little extra zing. Sometimes I add a few more red pepper flakes or a dusting of extra Parmesan—it just amps up the flavor and makes it look restaurant-worthy right on your own table.

Side Dishes

My favorite sides with this dish are a crisp Caesar salad or garlic bread to soak up any leftover creamy sauce. Roasting some broccoli or asparagus on the side adds a fresh, slightly crunchy contrast that balances the indulgence perfectly.

Creative Ways to Present

For a casual dinner with friends, I like to twirl the spaghetti into neat nests on the plate and garnish with a fresh basil leaf or edible flower petals for a pop of color. Serving in shallow bowls also keeps things cozy and helps everyone scoop up every last bit of that creamy goodness.

Make Ahead and Storage

Storing Leftovers

I usually pop leftover creamy garlic butter spaghetti into an airtight container and refrigerate it for up to 3 days. The sauce thickens a bit as it cools, but don’t worry—you can easily get it back to creamy with a little reheating trick.

Freezing

Freezing this dish is possible but requires some care. I recommend freezing the pasta and sauce separately if you plan on freezing it for longer than a week. When thawing, gently reheat on the stovetop over low heat, adding a splash of cream or milk to revive the sauce’s creamy texture.

Reheating

I reheat leftover creamy garlic butter spaghetti slowly in a skillet over low heat, adding a tablespoon or two of cream or milk to loosen the sauce. This keeps the pasta from drying out and helps the sauce regain its silky texture—definitely avoid the microwave if you want the best results!
