Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Penne rigate pasta: Forms the bulk of the dish and holds the sauce in its ridges.
Alfredo sauce: Provides the creamy, rich body that coats the pasta.
Mushrooms: Add moisture and savory, earthy flavor as they release and brown.
Roasted pepper strips: Add sweetness and soft texture to the sauce.
Parmesan cheese: Adds salty, savory depth and helps thicken the sauce as it melts.
Garlic: Contributes pungent aroma that mellows as it cooks in the oil.

The step that matters

Sautéing the onion, garlic, and pepper flakes. Cook over medium-high heat only until golden; burnt garlic turns bitter and taints the whole sauce, while the oil carries the aromatic flavors through the dish.
