What You’ll Need

You don’t need any fancy gadgets for this dish, just a few kitchen basics.

• A big pot for boiling the pasta.
• A large skillet for the sauce. A wide skillet works best because you’ll have plenty of room to mix everything together.
• A spatula or wooden spoon for stirring and breaking up the cream cheese.
• A colander or strainer for the pasta.

Can I Prep This Ahead of Time?

This dish tastes best when you eat it right away. But you can save some time by prepping a few things. You can chop your onion a day ahead and keep it in an airtight container in the fridge.

The sauce can also be made 1-2 days in advance. Just store it in the refrigerator, and when you’re ready to use it, gently reheat it on low heat. Add a little milk or water to loosen it up before you toss it with freshly cooked pasta.

Ingredients

Every great dish starts with good ingredients. This list is short, but every single item plays a key role in creating that signature creamy texture.

• 1/2 box spaghetti: This is the foundation of our dish. The thin strands are perfect for holding onto that delicious sauce.
• 1 tablespoon salt: For the pasta water. Don’t skip this! This is your only chance to season the pasta itself. It’s crucial for the final flavor.
• 1/2 stick butter: We use this to sauté the onion and add a rich, buttery flavor to the sauce.
• 1/4 onion, diced: The subtle, sweet flavor of the onion provides a perfect base. A white or yellow onion works great here.
• 1 cream cheese package (8 ounces): The secret ingredient for that incredibly rich and velvety texture. Use full-fat cream cheese for the best results.
• 8 ounces sour cream (or crema mexicana): Mexican crema is a bit thinner and tangier than regular sour cream. That’s why it works so well in this sauce. If you use regular sour cream, the sauce will be slightly thicker, but it will still be delicious.
• 1/2 teaspoon salt: To season the sauce itself. We’ll taste and adjust it later, but this is a great place to start.
• Parsley and Parmesan cheese (optional toppings): These are great for a fresh finish and a final savory note.

A quick note on substitutions:

• Sour Cream: No sour cream? No problem. You can use Greek yogurt for a tangier and healthier option, or even crème fraiche for a luxurious flavor.
• Onion: If you’re a garlic fan, feel free to add a minced garlic clove to the skillet with the onion.
• Butter: You can use olive oil instead, but the butter really gives the sauce a richer, more authentic flavor.

Step-by-Step Method

Alright, let’s get cooking! I’ll walk you through each step just as if we were in the kitchen together.

Step 1: The Pasta’s Grand Entrance

First, get your biggest pot and fill it with water. Put it on the stove and bring it to a rolling boil—you know, when the water is bubbling like crazy. Now, add your salt. Don’t be shy! This is your only shot at seasoning the pasta.

Next, add your spaghetti. Cook it according to the package directions until it’s “al dente.” That means “to the tooth”—it should be firm, not mushy.

Pro Tip: Before you drain the pasta, scoop out about a cup of that starchy pasta water. We won’t use it in this recipe, but it’s a great habit to get into. That water can rescue a sauce that’s too thick.

Once your pasta is ready, drain it and set it aside.

Step 2: Building the Velvety Sauce

While the pasta is boiling, we’ll start on the sauce. Put your large skillet on the stove over medium heat and add the butter. As it melts, add the diced onion. Stir and cook for about a minute. You’ll know it’s ready when the onion is translucent and the kitchen smells amazing.

Now, add the cream cheese. Break it up with your spatula and stir it into the buttery onions. It won’t fully melt into a liquid. It’s more like it will soften and break down into a creamy, lumpy mixture. This takes about 3-4 minutes. Keep stirring so it doesn’t stick to the bottom of the pan.

Next, it’s time for the sour cream and salt. Add them to the skillet and stir for just a minute. The sour cream will loosen the mixture and make it silky smooth. This is your chance to taste and adjust the salt. Remember, we salted the pasta water, so be careful not to overdo it!

Step 3: The Grand Finale

Here’s where the magic happens! Turn the heat off. This is a crucial step to prevent the sauce from breaking or separating. Add your cooked spaghetti directly into the skillet with the sauce.

Using tongs or two large spoons, toss the pasta with the sauce until every single strand is coated in that amazing creamy goodness. The leftover heat from the pasta and the skillet will be just enough to bring everything together perfectly. You’ll know it’s ready when the pasta goes from glossy to a beautiful, velvety white.

Variations & Customization

This dish is a fantastic canvas for your own creativity. Don’t be afraid to make it your own!

• For a spicier kick: Sauté a finely diced jalapeño or serrano pepper with the onion. Or add a pinch of cayenne pepper to the sauce for a subtle warmth.
• Protein power: This dish is often a side, but it can easily be the main event. Sauté some chopped ham, bacon, or shredded chicken and stir it in at the end. The savory, salty notes from the meat pair perfectly with the creamy sauce.
• Add some veggies: Stir in some roasted corn or poblano peppers, or sauté some sliced mushrooms with the onion. It’s a great way to add more texture and nutrients.

Serving & Storage

Congrats, your Mexican White Spaghetti is ready to be enjoyed!

Plating & Serving:

Serve the spaghetti immediately in a warm bowl. Garnish with a sprinkle of fresh parsley for a pop of color and a generous dusting of Parmesan cheese for a salty, savory finish. This dish goes great with grilled chicken, steak, or even a side of roasted vegetables.

Storage & Reheating:

While it’s best fresh, leftovers are still fantastic. Store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to reheat, the sauce might look a little thick. Just place it in a skillet over low heat and add a splash of milk or a little water, stirring constantly until it gets that luscious, creamy consistency again.

I wouldn’t recommend freezing this dish, since the dairy-based sauce tends to separate when it freezes and thaws.
