Step-by-Step Method:

Prepare the Pasta

Bring a large pot of salted water to a rolling boil. Add the pasta and cook until al dente (check package instructions for timing). Reserve 1 cup of pasta water before draining.

Melt the Butter

In a large mixing bowl, add the butter. Pour a few tablespoons of the hot reserved pasta water over it to melt it into a creamy consistency.

Combine

Toss the drained pasta into the butter. Add half of the Parmigiano-Reggiano and a splash of pasta water. Mix vigorously to coat every strand, creating a creamy sauce. Add more pasta water, a little at a time, to reach your desired consistency.

Finish with Cheese

Add the remaining Parmigiano-Reggiano and continue to mix until smooth. Adjust seasoning with salt and optional black pepper.

Serve Immediately

Plate the pasta while hot and garnish with extra cheese if desired.

Variations & Tips:

Variations:

Add a pinch of nutmeg for a slightly nutty flavor.

Incorporate sautéed mushrooms or peas for texture and variety.

Replace butter with olive oil for a lighter version.

Dietary Substitutions:

For a dairy-free version, use vegan butter and a plant-based cheese alternative.

Gluten-free pasta works well for those avoiding gluten.

Tips:

Use the highest quality butter and cheese for the best flavor.

Work quickly to keep the pasta hot for optimal sauce emulsification.
