Updated 2019 with Instant Pot instructions
What is Tex-Mex?
Tex-Mex is a cuisine is also known as Mexican American cuisine, made famous from Tejanos from Texas. It’s popular in American/Mexico border states, particularly Texas. I love Tex-Mex food! For this recipe, I took my favorite Tex-Mex flavors and added them to a beef roast. That’s pretty much it. Simple yet very flavorful. The spice rub is a homemade mixture of spices that you probably have already in your pantry. While I wouldn’t call this spicy, it does have a little bit of a kick to it. If you’re concerned about that, I suggest you lower the chili powder amount and/or omit the red pepper flakes.
Searing The Roast
To sear or not to sear? That always seems to be the question. When I use the slow cooker, I usually don’t take the time to pan-sear my meat beforehand however as you can see in the pics, this time I was feeling feisty so I did this time. If you don’t have time for that step don’t worry, your roast will still taste good. For the pressure cooker, searing is a part of the process so it’s included in the step. Depending on how tough of a cut, your meat might take longer than usual. A chuck roast only took 40 minutes in the pressure cooker for me however a rump roast the exact same size took 60 minutes. One of my main rules of thumbs with slow cooking meats is that you should cook the meat until it’s so tender it falls apart easily with a fork. I like to keep cooking my roast until it’s that tender.
What Kind Of Roast To Use?
You can pretty much use your preferred cut of beef roast whether it be chuck roast, round roast, rump roast. I used a chuck roast when I made this in the slow cooker and a round roast for the electric pressure cooker (Instant Pot). Don’t have a roast? You can use a cut like brisket for even a couple of pound of flank steak. Since the beef is being shredded down here, you have a few options here.
If you’re looking to make this low-carb, paleo, or whole30, all you need to do is omit the corn and black beans and use compliant enchilada sauce (easy to find or make your own). Did I mention is one of those recipes that will have your entire kitchen smell amazing?? It will.Print
