The Philly cheesesteak originated in the 1930s in Philadelphia’s South Street neighborhood and quickly became a working‑class staple. It represents the city’s love of beef, cheese, and simple, hearty sandwiches, and is often associated with sports venues and local pride.

In Pennsylvania you’ll find variations such as the “cheese whiz” version, a “provolone” version, and the “onion‑only” version. Some shops add sautéed mushrooms or hot peppers, but the core components remain thin‑sliced steak, a soft hoagie roll, and melted cheese.

Traditionally it is served on a soft, slightly crusty hoagie roll, topped with melted cheese (often cheese whiz) and optional sautéed onions. The sandwich is usually wrapped in paper to keep it warm and to allow the steam to meld the flavors.

Philly cheesesteaks are a go‑to food at sporting events, especially Philadelphia Eagles games, as well as at street fairs, market stalls, and casual gatherings. They’re also a popular late‑night snack after concerts or bar outings.

Flat‑iron steak offers a rare combination of tenderness comparable to filet mignon and rich beefy flavor similar to rib‑eye, while being more affordable and easier to slice thinly at home. This makes it ideal for both thin‑cut cheesesteaks and medium‑rare sandwich applications.

Traditional Argentine chimichurri uses parsley, garlic, oregano, red pepper flakes, red wine vinegar, and olive oil. Acceptable substitutes include using a mix of cilantro for a fresher twist, or swapping red wine vinegar with white wine vinegar, but the herb‑oil balance should remain.

Flat‑iron steak sandwiches pair nicely with classic sides like sweet potato fries, coleslaw, or a simple mixed green salad dressed with a light vinaigrette. A cold craft beer or a crisp cider also complements the beefy flavors.

Common mistakes include overcooking the thin steak strips, using too much oil which makes the sandwich soggy, and not wrapping the sandwich tightly enough, which lets steam escape and dries out the roll.

Sodium citrate acts as an emulsifier, preventing the cheese from separating and creating a smooth, pourable sauce that stays glossy as it cools. Without it, the cheese can become grainy or oily.

Yes. Cook the steak, let it cool, and store it in an airtight container in the refrigerator for up to 2 days. Keep the cheese sauce and chimichurri separate; reheat the steak gently and assemble just before serving.

The YouTube channel Ethan Chlebowski focuses on experimental home cooking, often testing ingredient variations and cooking techniques to determine the best methods for classic dishes, with a strong emphasis on meat preparation and flavor science.

Ethan Chlebowski combines scientific flavor frameworks (taste, aroma, texture, sight, physical, human factor) with side‑by‑side taste tests, whereas many other channels simply demonstrate a single recipe without systematic comparison of cuts or sandwich components.
