Lean pepper steak and celery stir-fry with lemon, garlic, soy, and a small butter finish for a high-protein weeknight bowl.
This lemon pepper steak celery stir-fry is built around lean sirloin, crisp celery, garlic, scallions, soy sauce, and a bright squeeze of lemon. It keeps the fast seared-beef feel of a classic pepper steak but swaps heavier sweet glazes for a sharper, cleaner finish.
The small amount of butter is used as a finishing ingredient, not the base of the sauce. That gives the pan juices a glossy texture while keeping the dish practical for a high-protein, lower-cholesterol dinner.
Chilling the beef briefly makes it easier to slice thinly, which is the biggest factor in a tender stir-fry. Cornflour helps the sirloin brown quickly and gives the soy, lemon, and butter enough body to cling to the steak.
Celery works especially well here because it stays crisp and fresh under high heat. Lemon peel adds fragrance while the juice, added off the heat, keeps the final flavour bright instead of flat.
Use the widest skillet or wok you have and sear the beef in two batches. If the pan is crowded, the sirloin will steam and lose the browned edges that make this simple sauce taste deep.
The celery only needs a short cook. Aim for glossy and crisp-tender rather than soft, then return the steak with soy sauce, a splash of water, and a small knob of butter to pull everything together.
One serving is 1 bowl: a quarter of the steak and celery mixture with about 180 g cooked rice. For a training day, add 50 g extra cooked rice or 1 piece of fruit on the side. For a rest day, reduce the rice by about 50 g and add extra celery or another vegetable.
For a leaner protein swap, use thinly sliced chicken breast or prawns. Tofu also works if pressed well and seared before the celery goes in. Good vegetable swaps or additions include broccoli, green beans, spinach, peas, mushrooms, onions, courgette, frozen mixed veg, or tenderstem broccoli.
Store leftovers in airtight containers for up to 3 days. Reheat in a hot skillet with a splash of water so the sauce loosens and the celery keeps more texture than it would in the microwave.

Set the sirloin in the freezer for 10 minutes so it firms slightly, then slice it thinly against the grain.
Toss the beef with a light pinch of salt, black pepper, cornflour, and brown sugar until evenly coated.
Heat a large skillet or wok over high heat. Add 1 teaspoon oil, then sear half the beef in a single layer for about 2 minutes without stirring. Flip for 20 to 30 seconds, then transfer to a plate. Repeat with the remaining beef.
Add the remaining oil, celery, garlic, spring onion whites, and lemon peel strips to the pan. Stir-fry for 1 to 2 minutes, just until the celery turns glossy but still has crunch.
Return the beef to the pan with soy sauce, water, and butter. Toss for 30 to 60 seconds until the sauce turns glossy and lightly coats the steak and celery.
Turn off the heat, squeeze in lemon juice to taste, and scatter over the spring onion greens.
Serve straight away over cooked jasmine rice, spooning any glossy pan sauce over the top.
