Bistek Tagalog: Calamansi Soy Beef with Onions
Recipe Guy
Filipino beef | Calamansi soy | Rice dinner
Onion rings deserve room in bistek Tagalog: their sweetness softens the sharp meeting of citrus and soy. Thin beef slices brown in batches, then finish in that savory sauce, leaving plenty to spoon over rice without burying the onions.
Why make it: This version gives U.S. cooks calamansi, lemon, and lime options, plus a tenderizing path for common supermarket beef cuts.

About This Recipe
Calamansi gives this beef its citrus edge; the listed equal-parts lemon and lime option keeps the recipe practical when calamansi is unavailable. The small amount of optional brown sugar rounds out the sauce rather than turning it into a sweet glaze.
Sirloin, flank, and skirt all benefit from thin slices across the grain. A wide skillet lets the surfaces brown before liquid is added. Once the onions and sauce join the pan, keep the finish gentle and check the beef instead of treating it like a long braise.
Cooking Notes
- Lift the beef from its marinade and blot it lightly before searing. Leave space between slices so the pan can brown them instead of collecting a pool of liquid.
- Slice the onions into rings of similar thickness. Stop their initial cooking when the edges soften; they will continue cooking once the reserved marinade and water enter the skillet.
Ingredient Notes
For the beef
Sirloin, flank, or skirt steak work if sliced thinly across the grain.
For the citrus
Calamansi is ideal. A half lemon, half lime blend is the easiest U.S. substitute.

Common Questions
Can I use lemon instead of calamansi?
Yes. Lemon plus a little lime gets closer to calamansi's bright flavor.
Why is my beef tough?
It may be sliced too thick or cooked too long. Use thin slices and simmer gently.
Can I use chicken?
Yes, but cook chicken fully and adjust the simmering time.
Can I make it saucier?
Add more water or broth and adjust soy and citrus at the end.
How should I slice flank steak for bistek?
Look for the long parallel lines in the meat and cut thinly across them, not along them. Keep the slices reasonably uniform so one batch does not contain both thick strips and thin scraps.
How can I loosen a bistek sauce that tastes too concentrated?
Use the listed water or beef broth to loosen it, choosing water if saltiness is the problem. Extra soy adds salt, while extra citrus makes the sauce sharper rather than less concentrated.
