This simple old fashioned tender, melt in your mouth pot roast, morphs into some mighty fine slow cooked beef for tacos. Crockpot roast beef tacos are beautifully flavored with Mexican seasonings and finished with a crunch of cabbage. And what about that flavor? It definitely shows up for the party. Super easy weeknight taco recipe.

How about grabbing that crockpot for some easy, hassle free, feed a crowd roast beef tacos? What kind of beef is best for shredding? As we know, the humble pot roast (chuck roast) benefits dramatically either slow roasted in the oven, or steeping in a slow cooker all day. Tender texture and pure beefy flavor.
Once that beef is slow cooked, it practically shreds itself. But please use your super-clean hands or two forks to make quick work for shredded beef for tacos.
So let’s put that pot roast to work for some slow cooker shredded beef tacos. It truly doesn’t get any easier than this recipe. Let’s take a look.

Ingredients for Slow Cooker Beef Tacos
- Chuck Roast. Good old fashioned pot roast is a relatively inexpensive cut of beef that starts out ornery and tough, but when slow roasted, it becomes meltingly tender. It becomes a perfect canvas for these crockpot beef tacos, as the long slow cook, mingled with Mexican spices turns out incredibly flavorful.
- Olive Oil. Since we’re using the olive oil to sear the chuck roast before we slow cook it, there’s no need to use an expensive brand that you’d use for a delicate vinaigrette. I keep a big bottle of Costco Extra Virgin Olive oil on hand for these types of jobs.
- Onion and Garlic: Friends don’t let friends eat Mexican food without onion and garlic. Fine dice the garlic and simply slice an 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 and fire roasted is a plus.
- 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 Chimayo Chile Powder and Hatch Red Chile Powder on hand, but if you can’t find any, Ancho Chile powder is a great substitute. Don’t use Chili (with an “i”) powder, that’s a blend of spices and is used to flavor Beef Chili.
- Cayenne Pepper: A moderately hot chile powder to add just another layer of flavor to this slow cooked beef for tacos.
- Ground Cumin: Cumin is a popular spice for Asian and Middle East curries, and is also commonly used in Mexican Food. It has a warm earthy flavor and in my humble opinion makes about anything taste better.
- Bay Leaves: 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.
Crockpot Beef For Tacos, a lifesaver weeknight meal
This crockpot roast beef taco recipe was a life saver this week. So very easy and with plenty of leftovers for a couple of quick dinners.
Simple with seasoning and big on flavor, the meat went into the crock pot before I went to work and I arrived home to an aromatic party that filled every nook and cranny of our house.
I used a good ‘ol chuck roast, and as with any slow cooked meat, it was fall apart, melt in your mouth wonderful. This recipe is popular in this house because we’re fans of ancho chili powder. And simply adding cumin, cayenne and bay leaves, I knew the flavors would be to our liking.
Once this meat is cooled and the beef shredded, just serve with your favorite taco toppings.
- A crunch of shredded cabbage.
- A slice of avocado.
- Salsa. We served this with my homemade Roasted Tomatillo Salsa. Or a tomato based salsa like this Essential Mexican Restaurant Style Salsa would be fabulous.
- Cotija Cheese: A Mexican crumbling cheese with a wonderfully tangy salty flavor works well for these roast beef tacos.
HOW TO WARM AND SOFTEN CORN TORTILLAS
You could take the time to fry and shape your own corn tortillas into tacos. But to keep things weeknight easy just heated up soft white 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.
You an also wrap store bought corn tortillas in foil and pop them in a 350 degree oven for about 10 minutes.
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.

That sounds fantastic and yes, the leftovers rock. I could see putting a little of this, some diced veggies on a tostada and topping it with a fried egg for breakfast.
OMG, sounds like a winner. Wish I still had leftovers so I could do that.
Shredded beef with those wonderful seasonings sounds like something I would love. Tri tip always cooks up so nicely, too.
It’s so exciting to see the real estate market pick back up. I have always considered my home equity to be my golden ticket investment and was just sick when my best asset lost its ass. 🙂
I’m loving my Costco try-tips. Well, I’ve been buying them for years and years. I just did a Santa Maria Tri-tip and will be blogging about that one. So wonderful. Hopefully your equity is seeing better days. Always a roller coaster.
These sound perfect for a busy day – which I have plenty of these days with gardening season upon us! Burning up all of those calories I deserve a few tacos 🙂
I like how you think Susan. With us food bloggers, any calorie burned is worth a celebration.
So I’m totally craving beef tacos now, betch ya I have them before the end of the week. It’s such good news that the housing market is taking an upward turn!
More like a soar. It won’t last forever. Real Estate is a roller coaster. You should try this recipe, it’s a good one.
It’s the greatest thing to come home to a crock pot meal after a long day at work. The house smells so good and it’s like there was no work to it! This sounds like a really good recipe.
You’ve got that right. Thanks Karen.
That’s what it was like when we bought our house two years ago… we probably paid about $5-8K more than we should have, but what can you do…. guess just hope it’s the same way when it’s time to sell 🙂
This taco recipe sounds divine!! And love the simplicity of making it in the crock pot!
It’s all relevant Jenn. If it’s the house of your dreams, then that’s not much to worry about. 🙂
Looks and sounds delicious LA and glad to hear business is booming. My daughter is a realtor and says she has been very busy also. This is coming to you from an RV park in Sevierville, TN as we are finally having our maiden voyage.
I knew your daughter was a Realtor, and glad to hear things are good in Texas also. Can’t wait to hear about the maiden voyage.
So you’re the lady that knows the whole closing by heart. Just was there and she was amazing how she knew the answers to everything and explained up front anything that needed explanation.
Cooking the tacos in the crock pot sounds like a great idea. Wish I hadn’t given mine away. BTW, I can now follow you on Feedly and Bloglovin’, so when I disappear from your mail list, you’ll know what happened to me. Sure don’t want to miss any good eats as Alton Brown would say.
Sam
Actually, it’s our closers that are the expert, I sell them and their knowledge and expertise. I’ve got about 4 crockpots, I’d be glad to give you one. 🙂
Lea Ann,
We really enjoy tacos and I do need to use my crock pot more! Every day seems to be a busy day in our lives, even with every attempt to simplify! So glad to hear the real estate market is picking up. We have a condo that my husband inherited that is in Florida. It has been for sale for 2 years and only lookers. We keep lowering the price, putting money into it to update it, but still no takers! And it is right on the inter coastal waterway! I keep praying for this burden to be removed from our lives! Keep sending the positive vibes!
Yes, I have friends that own property in Florida and they’ve tried to sell it for years. Really a good time to buy there. I’m so sorry to hear it’s a burden. Darnit. Positive vibes are headed your way.
(Sure wish I’d sold when there was a buying frenzy. Although there are so many condos down here, they don’t sell as well as homes.)
My crock pot is long gone, Lea Ann. I’m always tempted when I see so many slow cooking recipes, but then my family is grown and moved out of this area, so when I see something I’d like to make, I adapt it to stovetop. So thanks in advance for that…this looks marvelous and I love Tyler recipes!
Sometimes you just can’t time major decisions like that at just the right time. You and Sam have both given up your crockpots. You need to get at least a small one. Great to hear from you Barbara.
I like Tyler Florence, he definitely has some wonderful recipes. Looks fantastic!
Happy Blogging!
