A stir-fry is the most practical meal in a solo cook's repertoire: fast, one pan, uses up fridge odds and ends, and produces a real dinner rather than a snack. The technique takes a few tries to get right - but once it clicks, this becomes the meal you make on autopilot.
A wok is ideal but not necessary. A 20-22cm frying pan with high sides works fine for a single portion. The key is heat: get the pan properly hot before anything goes in. Oil should shimmer and move freely when you tilt the pan. Cold pan = steamed veg instead of stir-fried veg, which is a different and less good dish.
For what pan size and material works best for solo cooking generally, see the solo kitchen toolkit guide.
Every stir-fry is: protein + aromatics + veg + sauce + starch base. The components are interchangeable, which is what makes this the ideal use-it-up meal.
For a reliably crispy result with a vegetable stir-fry, this broccolini and mushroom stir-fry uses the same technique and is a good one to run through once before improvising.
1 tbsp soy sauce, 1 tsp sesame oil, 1 tsp rice vinegar, half a tsp sugar. Works with everything. ~30 kcal.
1.5 tbsp oyster sauce, 1 tsp soy sauce, splash of water. Richer, more umami, particularly good with beef or mushrooms. ~35 kcal.
Extra ginger (grated, a full teaspoon), two sliced spring onions added with the veg, finish with soy and a squeeze of lime. Lighter than the soy-based version. ~25 kcal.
1 tbsp peanut butter thinned with 1 tbsp hot water, 1 tsp soy, a squeeze of lime, half a tsp chilli flakes. Best with tofu or chicken and noodles rather than rice. ~80 kcal.
Stir-fries don't keep especially well - the veg softens and the sauce continues to cook into everything. Make fresh. What you can prep ahead: pre-slice the protein and store it raw in the fridge for up to two days, pre-mix the sauce and keep it in a small jar, and have cooked rice ready in the fridge (reheated with a splash of water in the microwave is fine).
