Ingredients and substitutions
- Olive oil – use any neutral oil to replace olive oil in this recipe. I recommend canola oil or vegetable oil.
- Beef broth – vegetable broth can also be used. If you’re in a pinch, use a beef bouillon cube with water.
- Flank steak – flank steak is the star of this recipe but feel free to substitute it out for a different cut of steak or if you’re in a pinch, ground beef. Cooking time may vary based on the substitute.
- Salt & pepper (to taste)
- Soy sauce – tamari or coconut aminos
- Lime juice – fresh or bottled lime juice will work. Use lemon juice in place of lime juice.
- Taco seasoning – use store-bought taco seasoning for easy cooking or make your own seasoning by combining chili powder, garlic powder, onion powder, crushed red pepper flakes, dried oregano and paprika.
- Garlic – fresh or jarred minced garlic is recommended but in a pinch, use garlic salt or garlic powder.
- Corn tortillas – flour tortillas or hard shell corn tortillas can be used to serve the tacos.
- Pico de gallo – use store-bought pico de gallo or make your own fresh. Another option would be to use any salsa. Guacamole, sour cream or any other crema will also work well.
- Red cabbage – use any topping of your choice.
- Avocado – use any topping of your choice.
- Cilantro (to garnish)
Which steak cut is best for tacos?
The best steak cut for tacos is flank steak! Flank steak is one of the leanest cuts of steak to purchase and is known as the most versatile cut of meat. It’s versatile because it can be grilled, broiled or sautéed super easily. If you aren’t able to get your hands on flank steak, the next best options to use for this recipe are skirt steak, hanger steak and sirloin steak.

Storing and reheating
If you have leftovers, store your toppings in a meal prep container. It is best to store them prepared and ready for easy assembly. You will want to the flank steak in a separate container because it is the only ingredient that you will want to warm up. When stored separately, the meat and toppings stored separately in the fridge will last up to 5 days!
When you’re ready to enjoy your tacos, warm up your tortillas in the microwave for a few seconds or on the stove and then warm your meat in the microwave for 1-2 minutes. Once the tortillas and meat are warmed, you can assemble your tacos and enjoy!
Freezing leftover steak
Leftover flank steak will freeze well in an airtight container or freezer bag for around 3 months. To keep the steak as fresh as possible, make sure it is stored with little to no air exposure. This will ensure that the steak doesn’t dry out, lose its flavour or get exposed to freezer burn. To reuse the frozen steak, begin by defrosting it in the fridge overnight then heat in the microwave or using the reheating instructions listed above.
