FAQs
Can I make these tacos ahead of time?
Absolutely! You can prepare the filling in advance and store it in the fridge for a day. Just assemble the tacos and bake when ready. This is a great way to save time on busy evenings.
Can I freeze cooked tacos?
Yes! If you have leftovers, you can freeze them for future meals. Just wrap them well to prevent freezer burn. They can be reheated in the oven directly from frozen.
How do I reheat leftover tacos?
Reheat your tacos in the oven at 350°F (175°C) for about 15-20 minutes, or until heated through. This keeps the shells crispy rather than soggy.
What can I use instead of taco seasoning?
If you don’t have taco seasoning, a mix of chili powder, cumin, paprika, and garlic powder can work well. Adjust the amount to your taste!
What are some common mistakes to avoid with tacos?
Make sure not to overfill the taco shells, as they can break easily. It’s also better to warm your shells for a minute in the oven before filling to avoid sogginess.
