Rigatoni with Flank Steak, Browned Mushrooms & Glossy Pan Sauce

Score: 8/10

A highly appealing, restaurant-style pasta dish that teaches solid pan-sauce techniques. Adjusting the mushroom cook time and adding a splash of acid will perfectly balance the final flavor profile.

Strengths

Properly instructs slicing the flank steak thinly across the grain to ensure tenderness.
Excellent use of reserved pasta water and butter to emulsify and create a glossy pan sauce.
Smart plating choice to place the sliced steak on top of the pasta, preserving its doneness and making for a beautiful presentation.

Issues

medium / flavor: The recipe lacks an acidic component to balance the rich umami, fat, and starch.
low / timing: Deeply browning 8 oz of mushrooms typically takes 8-10 minutes for the moisture to evaporate; 4-5 minutes is insufficient.
low / flavor: The recipe relies on soy sauce and broth for salt but fails to season the vegetables as they cook. Mushrooms and onions need a pinch of salt to draw out moisture and build base flavor.

Suggested fixes

Add 1 tablespoon of balsamic vinegar or a splash of dry red wine during the deglazing step to introduce much-needed acidity.
Increase the suggested mushroom cooking time to 7-8 minutes.
Instruct the cook to lightly season the mushrooms and onions with kosher salt as soon as they enter the skillet.
