Your Favorite Slow Cooker Pot Roast, with a Mexican

I’m telling you now…this slow cooker pot roast recipe could set the record for fastest and easiest clean-up of a dinner recipe ever.

The reason there’s hardly any clean up is thanks to Reynolds Slow Cooker Liners. The liners fit any 3- to 6.5-quart slow cookers and come in handy when making a recipe that needs to be lifted out of the Crockpot to serve (like cakes or egg dishes) or when cooking a recipe that could bake onto the sides of the crock (like this cheesy buffalo dip or this chicken fajita chili) or when you have a soupy broth to strain, like today’s Mexican pot roast recipe.

Reynolds liners are BPA-free and are made with a special heat resistant material that holds in the ingredients without puncturing or tearing, so feel free to use for your heartiest meals too.

As for this insanely tender, super juicy, fall-apart pot roast that’s infused with a little Mexican flair — I just know you’re going to love it, too.

Enjoy!

Ingredients for Mexican pot roast

Heidi’s Tips for Recipe Success

Brown the roast to add lots more flavor. Browning the chuck roast before slow cooking it adds lots of flavor without dirtying too many dishes.

Beef chuck roast makes for the most tender pot roast. I’ve experimented with various cuts of beef over the years, and I always fall pack on the humble chuck roast to make pot roast. It’s well marbled without being too fatty, and as the collagen in the meat breaks down it becomes fall-apart tender like you wouldn’t believe.

You can cook it on ‘high,’ but ‘low’ is best. Chuck roast needs to cook longer than other cuts of beef to become super tender. I’ve made this recipe in about 4 hours on high and it does work, but cooking it for 8+ hours on low is so much better. The longer cook time gives the tough connective tissues time to soften and really break down and for the flavors to develop.

What’s in This Recipe?

Adding the ingredients to a slow cooker to make pot roast.
(I used the slow cooker function of my Instant Pot this time)

The full recipe, with amounts, can be found in the recipe card below.

  • Boneless chuck beef roast — You’ll want one that’s 2.5 to 3 pounds.
  • Mexican spices — I flavored the pot roast with a blend of smoked paprika, ground cumin, and chili powder to add a subtle Mexican flavor.
  • Vegetables — The pot roast is slow cooked with onion, celery, garlic, and carrots, all of which add tons of aromatic flavor.
  • Beef bouillon — This is my secret ingredient for making intensely beefy-tasting pot roast.
  • Oil — I used olive oil when browning the chuck roast, but any cooking oil will do.

How to Make Mexican Pot Roast in a Slow Cooker

  1. Brown the chuck roast on all sides. I know it’s one extra step, but this causes what’s known as the Maillard reaction, which is a fancy way of saying that all of the color the beef develops when seared translate to rich, savory FLAVOR.
  2. Line your slow cooker insert with a Reynolds Slow Cooker Liner. Then, add in all the ingredients.
  3. Cook until the pot roast is fall-apart tender. After the meat is cooked, I shred it and mix the broth back into the meat for even more flavor.
  4. Garnish and serve! A sprinkling of cilantro adds to the Mexican theme and a few warm tortillas on the side take the place of traditional Sunday dinner rolls for wrapping.

And after that? The liner is tossed in the trash, the plates go into the dishwasher and we.are.done.

FAQs

How long does pot roast need to cook in a slow cooker?

I cook this Crockpot roast for 4 hours on high or 8 hours on low. Personally, I think the longer cook time at the lower heat delivers the juiciest, fork-tender texture, though.

Can I make this in an Instant Pot?

You can make this homemade pot roast using the slow cooker function on your Instant Pot (that’s what I did this time actually!).

However, I haven’t tested this recipe using the pressure cooker function so I can’t speak to whether this recipe will work that way.

How can you tell when pot roast is done cooking?

You’ll know the pot roast is finished cooking when it’s tender enough to shred with two forks. You can also shred it in a stand mixer, but I prefer using two forks.

Is this spicy?

Don’t be mislead to think this recipe is spicy or overpowered with Mexican chile heat. In fact, you won’t find a chile in it, except for the ground chili powder mixed with ground cumin and a touch of smoked paprika that delivers all of that Mexican flavor.

Can I make this without the Mexican spices? (i.e. a “normal” pot roast)

Yes! If you’re looking for a classic pot roast recipe, I suggest making my mom’s family-famous pot roast recipe instead. It can be made in the slow cooker, too!

My Favorite Pot Roast Sides

Unsure what to serve with your Mexican-style pot roast? These buttery potatoes are my go-to, but I have a few other sides I cycle through. Here are a few of my favorites:

Storage Tips

Pot roast will last up to 5 days in the fridge or 3 months in the freezer (the meat is so tender and juicy, which makes it freeze amazingly well). If you freeze the pot roast, be sure to add some of the broth to the freezer container as well so the meat doesn’t dry out.

Leftovers are especially delicious in soups and sandwiches, and you can also use the shredded pot roast to make beef tacos!

    Came out perfectly! I checked my roast at 3 hours and it was done. Definitley will make again. Never would have thought OJ would be the secret ingredient here. Sooo flavorful!

  3. Kevin

    I’m making this tomorrow for someone who can’t handle spice. So I’m gonna leave out the chile powder and sub in a tomato. Should I leave out the cumin as well?

    • Heidi Larsenheidi

      Hi Kevin, the cumin doesn’t add heat, only flavor. So if you’re worried about the spiciness in that way, leaving cumin in would be fine.

    I think this is one of the most significant information for me. And i’m glad reading your article. But should remark on some general things, The web site style is perfect, the articles is really great : D. Good job, cheers

  5. Judy

    As much as I LUV eating the onions and celery I always add to roasts and big pots of chicken, I always leave a few and use my immersion blender to make the broth even better~yes, I’ve been known to drink it from a cup or bowl!!

  6. Mahiuddin Sharif

    The Mexican roast looks tasteful. I am an enthusiast to try this recipe for my family. Sooth to say, I actually love this slow cooker recipe. Thank your so much for this awesome food ideas.

  7. Susan

    When you say 2 teaspoons of beef boullion which form of beef boullion are you referring to? Powder, granules? I plan on making this tomorrow but I am going to use “Better Than Bouillon” instead so I am trying to figure out the conversion! Thanks!!!

  8. Trisha

    This is a delicious recipe, but I’ll admit I was a bit turned off by the beef bouillon, as I like to keep MSG out of our food at home. For those who share my concerns, I’m happy to report that replacing the water + bouillon with one cup of unsalted beef broth worked just fine & I intend to make this recipe over & over again!

  16. Kim | a little lunch

    To me, washing out a crock pot is a small price to pay for the convenience of having dinner at the ready (teasing me with its aromas on the countertop all day), but hey — I’ll give those liners a try! Thanks for your review and recipe.

  18. Kay

    I use those slow cooker liners ALL the time! Never a Crock-Pot to clean with those on hand. I always have a spare box because I don’t ever want to run out!

  21. jude

    oh yum……this looks so good
    But I’m confused. The pictures all show small red potatoes but the recipe doesn’t mention them.

    • Heidi Larsenheidi

      Good eye Jude! I have that recipe coming up separately and served them on the side (didn’t cook them with the pot roast), so stay tuned!!

  22. Jill

    I confess, I haven’t even read the full post yet – I rushed to comment so I could say that I LOVE these liners. I only learned about them in the last year, and they are AMAZING. I made a big roast on the weekend for my family (all 11 of us), and I think my mother-in-law was willing to fight me for the remaining liners in the box. She’d never heard of them, nor had my sister-in-law. Seriously giving them as stocking stuffers for those two this year.

    Okay. Back to the recipe ;)
