Why White Sauce Penne Pasta Is So Popular

White sauce pasta has roots in classic French cuisine, where béchamel is one of the five “mother sauces.” Over time, it traveled across Europe and into Italian-inspired kitchens worldwide. Today, it’s a staple in home cooking, especially for those who enjoy creamy textures without tomato-based acidity.

Penne is the ideal pasta shape for white sauce. Its tubular form and ridged surface trap sauce inside and out, ensuring every bite is coated. Unlike long noodles, penne is easy to serve, easy to eat, and perfect for thick, creamy sauces.

Ingredients for White Sauce Penne Pasta

Penne pasta
Unsalted butter
All-purpose flour
Garlic cloves (minced)
Milk (warm, full-fat preferred)
Heavy cream (optional, for extra richness)
Grated parmesan cheese
Salt
Black pepper
Italian seasoning or dried oregano
Red chili flakes (optional)
Fresh parsley (for garnish)

Step-by-Step Instructions

Cook the pasta
Bring a large pot of salted water to a boil. Add penne pasta and cook until al dente according to package instructions. Reserve ½ cup of pasta water, then drain and set aside.
Prepare the roux
In a wide pan over medium heat, melt the butter. Once melted and slightly bubbling, add the flour and whisk continuously for 1–2 minutes until it smells lightly nutty but hasn’t browned.
Add garlic
Stir in the minced garlic and cook for 30 seconds, just until fragrant. Avoid browning.
Add milk gradually
Slowly pour in warm milk while whisking constantly to avoid lumps. The mixture will thicken gradually.
Season the sauce
Add salt, black pepper, Italian seasoning, and chili flakes if using. Stir well.
Add cream and cheese
Pour in heavy cream (if using) and grated parmesan. Stir until cheese melts and the sauce becomes smooth and glossy.
Adjust consistency
If the sauce is too thick, add reserved pasta water a little at a time until desired consistency is reached.
Combine pasta and sauce
Add cooked penne to the sauce and toss gently until fully coated.
Final taste and garnish
Taste and adjust seasoning. Garnish with fresh parsley and extra parmesan before serving.

Pro Tips for Perfect White Sauce Pasta

Always use warm milk to prevent lumps.

Pasta water is your best friend for adjusting texture.
Grate cheese finely so it melts smoothly.
