Perfect for a casual dinner or a festive gathering, these tacos combine savory beef fillet with the fragrant flavors of chili powder and oregano.

Instructions:

1. Prepare the Beef:
- Slice the beef fillet into thin strips or bite-sized pieces for easier cooking and eating in tacos.

2. Season the Beef:
- In a small bowl, mix together the chili powder, dried oregano, sugar, and 1/2 teaspoon of salt.
- Rub this spice mixture all over the beef strips to ensure they are well coated. Set aside to marinate for at least 15 minutes.

3. Prepare the Onion:
- Peel and slice the onion into thin rings or half-rings, depending on your preference.

4. Cook the Beef:
- Heat the vegetable oil in a large skillet over medium-high heat.
- Once the oil is hot, add the seasoned beef strips. Cook for about 5-7 minutes, stirring occasionally, until the beef is browned and cooked through.
- Remove the cooked beef from the skillet and set aside.

5. Cook the Onion:
- In the same skillet, add the sliced onion and the remaining 1/4 teaspoon of salt.
- Cook, stirring frequently, until the onion is softened and lightly caramelized, about 5 minutes.

6. Warm the Tortillas:
- While the onions are cooking, warm the tortillas. You can do this by heating them in a dry skillet over medium heat for about 30 seconds on each side or by wrapping them in a slightly damp cloth and microwaving them for about 30 seconds until warm and pliable.

7. Assemble the Tacos:
- Lay each tortilla flat and place a portion of the cooked beef in the center.
- Top with a generous amount of the caramelized onions.
- Optional: Add any additional toppings you like such as chopped fresh cilantro, sliced jalapeños, or a squeeze of lime juice.

8. Serve:
- Serve the steak tacos immediately while everything is warm and enjoy!

Steak tacos with oregano and onion FAQ:

What’s the best way to ensure my steak is cooked to the right doneness?

For steak tacos, aim for medium to medium-rare doneness, which is typically around 130-145°F (54-63°C). Use a meat thermometer to check the internal temperature of the beef while cooking.

Can I make these steak tacos in advance?

Yes, you can prepare the beef and onions ahead of time. Cook them, then store them separately in the refrigerator for up to 3 days. Reheat them in a skillet before assembling the tacos.

What type of tortillas work best for these tacos?

Corn tortillas are traditional and add great flavor, but you can also use flour tortillas if you prefer. Both work well when warmed before serving.

What can I use instead of beef fillet?

You can substitute beef fillet with flank steak, skirt steak, or even chicken if you prefer. Adjust cooking times as needed based on the thickness of the meat.

How should I store leftover cooked steak tacos?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat the beef and onions before serving again, and warm the tortillas separately.

Tips:

- For the best results, let the beef fillet rest at room temperature for about 30 minutes before cooking. This ensures even cooking.

- Use fresh, soft tortillas for the best texture and flavor. Warm them up on a dry pan before serving.

- Be sure to thinly slice the onion; this helps it cook quickly and caramelize beautifully.

- After cooking the beef, let it rest for a few minutes before slicing to keep it juicy.

- Customize your tacos with additional toppings like fresh cilantro, lime wedges, or a sprinkle of cheese to add extra flavor.
