Ground beef stir-fry is one of those dinners that looks like nothing on paper and then becomes the meal everyone asks for again. The beef browns fast, the sauce takes 30 seconds to mix, and the whole thing is done before the rice finishes cooking. At under $3 per serving, it's also one of the cheapest weeknight options around.
Mix the soy sauce, oyster sauce, hoisin, and sesame oil together in a small bowl before you start cooking. This is the move that separates a stir-fry that comes together smoothly from one where you're fumbling with bottles over a hot pan. The cornstarch slurry goes in at the end to thicken everything.
The vegetables are entirely flexible - frozen peas, corn, shredded cabbage, bok choy, mushrooms, and snap peas all work. Add a teaspoon of chilli paste to the sauce for adults; keep a mild portion for kids and add heat at the table. Swap ground beef for ground turkey or ground pork with no other changes needed.
The stir-fry reheats well over medium heat in a skillet with a splash of water to loosen the sauce. Microwave works in a pinch but the veg softens. Cooked rice keeps for 4 days in the fridge - batch-cooking it on Sunday is the single biggest time-saver for a recipe like this. Day-old rice actually fries better than fresh, so leftovers improve the next batch.
