Steak sandwich made with thinly sliced leftover steak, beetroot and caramelised onion

The best leftover steak recipes slice the cooked steak thin, across the grain, and add it at the very end so it heats through without overcooking. That simple rule turns last night's steak into sandwiches, quesadillas, salads, fried rice, stir fries and a weekend breakfast hash.

Below are 10 quick ideas grouped by style, a table matching each to the best leftover cut, and a short guide to how long cooked steak keeps in the fridge and how to reheat it safely.

Sandwiches and Wraps

The Ultimate Aussie Steak Sandwich

Thin slices of leftover steak warmed briefly in a hot pan with caramelised onion, then piled into a toasted roll with beetroot, lettuce, tomato and cheese. Rump and porterhouse both work, and slicing them thin keeps every bite tender.

Steak Sandwich Salad

All the flavours of a steak sandwich, served as a salad. The steak sandwich salad recipe is written for freshly seared rump or porterhouse, but cold sliced leftovers suit the rocket, roasted tomatoes, croutons, beetroot relish and mustard mayo too.

Roast Beef Sandwich with Horseradish Mayo

A deli-style sandwich of thinly sliced beef, peppery horseradish mayo, rocket and pickles on good bread. Swap the roast beef for cold leftover steak sliced as thin as you can. Eye fillet and scotch fillet leftovers stay especially tender served cold.

Steak Quesadillas

Chopped leftover steak with cheese, capsicum, spring onion and a little chilli, toasted between tortillas until crisp and melting. The steak heats through as the cheese melts, so it stays juicy. Any cut works, and they are ready in about 15 minutes.

Salads and Bowls

Steak fried rice made with diced leftover steak, egg, peas and spring onion

Thai Beef Salad

Cold leftover steak sliced thin and tossed with mint, coriander, cucumber, chilli and a sharp lime and fish sauce dressing. Lean rump suits it best, because the bright dressing loves its beefy flavour. There is no reheating, so the steak stays tender.

Steak Fried Rice

Day-old rice and diced leftover steak stir-fried with egg, peas, spring onion and soy. Fry the rice and vegetables first, then add the steak for the last minute so it heats through without drying out. Marbled scotch fillet leftovers add extra flavour.

Hot Pan Dinners

Steak fajitas made with sliced leftover steak, charred capsicum and onion

Beef and Broccoli Stir Fry

Broccoli and onion stir-fried in a glossy oyster sauce, with thinly sliced leftover steak tossed through at the end. The hot sauce does the reheating, so the beef stays tender. Rump or porterhouse leftovers suit it, ready in the time the rice takes.

Steak Fajitas

Capsicum and onion charred in a hot pan with fajita spices, then sliced leftover steak added for the final minute or two. Pile it into warm tortillas with salsa, avocado and sour cream. Rump leftovers slice into neat strips and suit it best.

Roast Beef Stroganoff

A roast beef stroganoff is made for leftover roast beef or fresh rump, and thinly sliced leftover steak fits right in. Mushrooms, onion, paprika, Dijon and sour cream make the sauce in about 30 minutes; stir the beef in last so it just heats through.

Steak and Egg Breakfast Hash

Crispy diced potato fried with onion and capsicum, topped with chopped leftover steak and a fried or poached egg. Add the steak once the potatoes are golden so it heats through without toughening. A hearty weekend breakfast that uses up any cut.

How Long Leftover Steak Keeps and How to Reheat It

Cooked steak keeps in the fridge for two to three days. The Food Safety Information Council advises cooling leftovers quickly in a shallow container, refrigerating them once the steam stops rising, using or freezing them within two to three days and reheating them until steaming hot. Thin slices get there in a minute or two in a hot sauce, which keeps them tender. Those two to three days assume you are storing meat safely, and how long steak lasts in the fridge shrinks quickly if you are not.
