What cut of steak is best for steak bites?
Sirloin is the weeknight champ: flavorful, affordable, and easy to cube. Ribeye is the luxurious option with more marbling. Tenderloin is very tender but milder and usually pricier.
How do I keep steak bites from getting tough?
Three rules: pat dry before seasoning, do not crowd the pan, and do not overcook. Because the pieces are small, carryover cooking is modest. Pull them just under your target doneness and let them finish while they get tossed in the hot sauce.
Quick temp guide (pull temps): rare 120 to 125°F, medium-rare 125 to 130°F, medium 135 to 140°F. The exact finish depends on cube size and how hot your pan runs.
Can I make these without a cast iron skillet?
Yes. Any heavy-bottomed stainless steel skillet works great. Nonstick is not ideal for searing, and you will miss out on the browned bits that make the sauce taste expensive.
Is the sauce very lemony?
It is bright, not sour. Start with 1 tablespoon lemon juice, taste, then add the last tablespoon if you want more tang. This is your kitchen, not a test.
Can I make this dairy-free?
Yes. Swap butter for a good olive oil or dairy-free butter and keep everything else the same. The sauce will be a little less silky, but still bold and tangy.
Any ingredient notes for dietary needs?
Worcestershire sauce typically contains anchovies, so it is not vegetarian and may not work for some fish allergies. If needed, swap in a vegetarian Worcestershire or use a splash of soy sauce plus an extra squeeze of lemon. (Also note: soy sauce contains soy and often wheat.)
