So let’s put a humble chuck roast beef to work for some crock pot roast beef tacos. It truly doesn’t get any easier than this recipe. Let’s take a look.
Ingredients for Roast Beef Tacos

- Chuck Roast: Good old fashioned pot roast (chuck roast) is the best choice for crock pot roast beef tacos. It’s a relatively inexpensive cut of beef that starts out ornery and tough. But when slow cooked in the crock pot, the long cooking time allows the connective tissues to break down into rich geletin. it becomes meltingly tender and becomes a perfect canvas for taco shells. The long slow cook, mingled with Mexican spices turns out incredibly flavorful.
- Neutral Oil. Canola oil or vegetable oil work well here. And don’t be afraid to use lard.
- Onion and Garlic: Friends don’t let friends eat Mexican food without onion and garlic. Fine dice the garlic and simply slice a lare onion to flavor these roast beef tacos. Easy!
- Canned Tomatoes: Canned tomatoes are a miracle product for the home cook. Especially during those Winter months when the stores only offer sad flavorless hot house tomatoes. Choose canned tomatoes that are chopped or diced. The smaller chop, the more they’ll break downinto the sauce.
- New Mexico Chile Powder: Red Chile powder from New Mexico is a pure treat. Beautiful in color and flavor and just right spicy. I keep a supply of New Mexico Chimayo Chile Powder and Hatch Red Chile Powder on hand, but if you can’t find them, Ancho Chile powder is a great substitute. Don’t use Chili (with an “i”) powder, it’s a blend of spices used to flavor Beef Chili style recipes.
- Ground Cumin: Cumin is a popular spice for Asian and Middle East curries, and is also commonly used in Mexican Southwest recipes. It has a warm earthy flavor and in my humble opinion makes about anything taste better.
- Bay Leaf: Add such a distinctive flavor for roast beef. Pungent and herbal, it adds a lovely depth of flavor to this dish. Just don’t forget to remove them after cooking. They’re sharp and remain sharp even after an all day cook in the crockpot.
Best Beef Cuts For Roast Beef Tacos
As I mentioned above, I prefer a good old fashioned chuck roast. Here are other options and the trade-offs.
- Beef Brisket will work well here. Rather than purchasing a whole brisket, look for a point cut brisket. A whole brisket can be cut into two sections, the flat point, and the point. The point is a thicker piece of meat which will work better for this long-cook recipe. The trade off is price. Brisket is a more expensive cut of meat that a chuck roast.
- Rump Roast: You can use a rump roast, but keep in mind it comes from the hindquarter of the animal and is a leaner cut of meat. It is better for sliced roast beef options. Save this cut to make your Sunday Pot Roast dinner.
The Only Crock Pot Roast Beef Taco Recipe You’ll Need
Easy Step by Step Instructions


- Step 1: Season all sides of the beef with a fair amount of salt and pepper and flour both sides. In a large Dutch oven, or skillet heat 2 tablespoons of oil over moderately high heat. Add the pot roast and brown. Get a nice brown crust on each side of the beef.
- Step 2: Get a good brown crust on the two large flat sides of the meat.
Pro Tip: Don't skip searing the meat. This is a crucial step in getting the most flavor out of this meal. Searing creates what is technically called Maillard reaction. Maillard reaction is the process where a crust is created. Simply stated, it's responsible for the complex flavors and aroma that makes bread taste toasty, and a grilled or seared burger taste charred. It's a technique that brings science to your cooking skills.


- Step 3: Place the beef in the crockpot. Sprinkle the garlic and onion over the beef. Add the crushed tomatoes, water and spices. Cook in crock pot on low for 6 – 8 hours.
- Step 4: Let meat cool in the liquid. Use forks to shred meat and set aside.
Shredding and Finishing – Texture Matters
- Shredding: I personally feel that using two forks is the best way to shed roast beef. As I mentioned above, if cooked properly, the beef will practically shred its self. You can also use your hands as quick tools.
- Crisping: If you want a crispier taco, once the meat is shredded, place it on a sheet pan and broil the meat for just a couple of minutes in the oven.
Toppings and Sauces That Work Well for Roast Beef Tacos

Once the chuck roast is cooled and the beef shredded, just serve with your favorite taco toppings.
- A crunch of shredded cabbage. Cabbage is used commonly for a taco topping.
- A slice of avocado or some homemade Chunky Guacamole.
- Salsa is always welcome. We love these Mexican pulled beef tacos with a drizzle Roasted Tomatillo Salsa. Or a tomato based salsa like this Essential Mexican Restaurant Style Salsa works well here.
- I love sliced raw jalapeno peppers or chopped raw onions.
- Cotija Cheese: A Mexican crumbling cheese with a wonderfully tangy salty flavor works well for these shredded beef tacos.
- Chopped cilantro: Yes please.
- Lime Wedges: Serve tacos with a side of lime wedges. A splash of lime juice will brighten the flavors of any taco.
- Mexican Pickled Onions are always a good choice for any taco and they’re so easy to make.
- Tortillas: Serve shredded beef on either yellow corn, white corn, or even small street style flour tortillas.
Tips For Success
- Adjusting the spice level: New Mexico Red Chile Powder can deliver quite a punch of heat. This recipe calls for using 1 – 2 Tablespoons. Start out the lesser amount. Once the meat is done cooking in the crockpot, you can always sprinkle on some more once you start shredding the meat.
- Use The Right Cut Of Meat: Chuck roast is easy to find in the grocery store. And it’s usually a cheaper cut of meat. I prefer it for this recipe. But please don’t hesitate to try a small brisket, or even flank steak.
- After shredding the beef, make sure to strain out the onions, tomatoes and some of the sauce to mix into the meat.
Storage
- Store any leftovers in an airtight container in the refrigerator for up to five days. I like to heat any left over shredded beef in the microwave in 15-30 second increments. Small bursts of heat in the microwave, and using the 50% power feature won’t compromise the tender texture.
- Meat for shredded beef tacos can be frozen for up to 6 months. I like to use freezer safe zip-lock style baggies, that way you can store them flat to optimize freezer space. Let the meat thaw in the refrigerator overnight.
How To Warm Corn Tortillas
You can’t just take a corn tortilla out of the package and use it. You must warm it to make it pliable for these shredded beef tacos.
You could take the time to fry and shape your own corn tortillas into tacos. But to keep things weeknight easy just heatup soft white or yellow corn tacos.
Warming corn tortillas in the microwave:
- Drizzle about three tablespoons of water over a clean kitchen towel.
- Wrap your corn tortillas in the towel.
- Slide the package into a gallon sized plastic bag. Don't seal the bag.
- Microwave the tortillas at 50% power for four minutes.
- This creates a steamy packet. Let sit 2 -3 minutes inside package before using.
Warming corn tortillas in the oven: You an also wrap store bought corn tortillas in foil and pop them in a 350 degree oven for about 10 minutes.
Warming torn tortillas stove top: My favorite way! Place individual tortillas directly on the grate of your gas stovetop. Turn the flame so it’s the exact size of the tortilla. Toast them for about 15 seconds per side, or until the edges are starting to brown.
Or you can purchase this incredible microwave tortilla warmer that works like magic. I have two because they work well for serving tacos to a crowd. You can heat corn tortillas in one and flour in the other – then get that taco party started.
Flour tortillas are easily warmed in the microwave to make them soft, steamy and pliable. No need to use the corn tortilla bag method, just place them on a plate and heat until warm.
Questions You May Have
To prepare roast beef tacos stovetop, start by searing the beef, adding the spices and canned tomatoes. I would add a cup of beef broth to prevent it from drying out. Cover and cook over low heat until the chuck roast is very tender. About 3 hours. Monitor the level of liquid as you may likely need to add more broth. This is especially important when using a heavy Dutch oven like a Le Creuset.
You can reduce the cooking time by half, by using the “high” setting on your crock pot. But I simply wouldn’t recommend it. Cooking a chuck roast low and slow in the crock pot will insure that the meat will be fall apart tender and very shreddable. A quicker cook time may compromise the texture of the meat.
I love those little Street Taco flour tortillas. So the answer is a resounding yes. If you use flour tortillas, be sure to drizzle them with salsa verde, the flavors are spot on. As far as flour vs. corn tortillas, they’re both delicious options for any taco.
There’s only one easy answer. It’s not been cooked long enough. Keep cooking until the meat is fall apart tender.
