Beef Fajitas In the Oven? I know, it seems like a weird concept especially since they seem like something that should only come out on a sizzling plate at your favorite Tex-Mex place, but they are easy enough to make at home! Better yet? You can do them in the oven, on just one pan.
Let’s start with a few frequently asked questions:
The most common way to tenderize meat is to use a marinade. The other way to do it is to cut the meat across the grain – that is what we are doing with this recipe! You cook it hot and fast, not letting it set in juices. Above all, do NOT cook your meat in the microwave – that is certainly the way to get tough meat.
What makes a fajita a fajita?
From Wikipedia:
Fajita is a Tex-Mex, Texan-Mexican American or Tejano, diminutive term for little strips of meat cut from the beef skirt, the most common cut used to make fajitas. The word fajita is not known to have appeared in print until 1971, according to the Oxford English Dictionary. (The word faja is Spanish for “strip”, or “belt”, from the Latin fascia, “band”) Although fajita originally referred to these strips of beef skirt, fajitas now are made with a variety of fillings, such as green/red/yellow peppers, onions, chilies, and jalapeño peppers.
Soooo, these are strips of meat and veggies that are quickly cooked with a hot heat source.
What is the difference between Carne Asada and Fajitas?
While both Carne Asada and fajitas are made with skirt steak or flank steak, both are thinly sliced and usually marinated. Carne Asada is not served with grilled onions and peppers
Now let’s get to those Fajitas!
This is how dinner should be: Fast, easy, and full of flavor! You can have this tasty meal on the table in 30 minutes if needed, or you can marinate the steak ahead of time with some olive oil and the dried spices listed below for extra flavor.
For best results, use a three-quarter sized sheet pan for this recipe versus the more common 13” x 18” half sheet pan. This will allow extra room to spread the vegetables out into a single layer without overcrowding while roasting.
You can prep this in roughly 10 minutes, doing most of the work in advance – even a day or two! That makes it just a cook time of 15-20 minutes and before you know it? You have a great meal that serves 6 people.
Keep in mind that sheet pans come in several sizes. The most common – the half sheet pan – measures 13” x 18,” while the larger three-quarter sheet pan measures 15” x 21.” The three-quarter size works well for many recipes in this package because it allows extra room for the vegetables to be spread out in a single layer without overcrowding.
