There are two main methods of cooking Mexican Pot Roast in the Instant Pot. I’m not going to say which is best, because it depends on how much time you have and how important tradition is to you. I’m going to show you both methods and you can decide for yourself which you like better.

Mexican Pot Roasters are known for their meat, so I decided to share an easy recipe for traditional pot roast or Carnitas. These recipes allow you to cook the meat from the inside out. This allows for even cooking and that traditional succulent and flavorful flavor.

While the Instant Pot is a well known brand, many people may not be aware that this device comes in a slew of different models. The Instant Pot comes in two versions, the Duo and Duo Plus. The Duo Plus has a few extra features, including one that allows you to set a timer, which is useful if you are cooking for a family and want to make sure you do not leave them waiting for a long time. The Duo Plus also comes in a larger version, the Duo 8, which has all the same features of the Duo Plus, but with even more cooking space..

This Pot Roast in Mexico has delicate beef chunks in a delicious tomato-based sauce, similar to Ropa Vieja.

Ropa Vieja is a Cuban meal made with shredded meat, usually flank steak, with rice and black beans. I use a Chuck Roast for this variation and cook it in the Instant Pot, thus the name Mexican Pot Roast. 

The ultimate product is shredded tender, delicious beef served with steaming rice and black beans.

Seasonings and Ingredients

Beef Chuck Roast, Tomato Sauce, Chili Powder, Garlic, Onion, Bell Pepper, and Vinegar

The taste profile is extremely close to that of Cuban Ropa Vieja, as I previously said. I also like to finish with a splash of vinegar to give some brightness.

If you prefer olives, instead of vinegar, add a few spoonful of olives and the brine towards the end.

Chili Powder- I like the sweet and smokiness of ancho chili powder, but ordinary chili powder would suffice.

Garlic- Fresh minced garlic gives the greatest taste, although granulated garlic would suffice if you don’t have any. 

Bell Peppers- I prefer to cook the red bell peppers with the meat since they melt into the sauce, but if you want more crunch, add some sliced bell peppers towards the end. 

I used a delicious yellow onion, but I’ve also tried it with sliced white onion; both work, but the yellow onion adds a touch of sweetness.

What Kind of Beef Should You Use?

Roasted Chuck This is the cut of beef I used, and I tested the recipe with it. If there’s a lot of extra fat, I cut some of it off, but I leave the majority of it on for taste and moisture. 

I tried this recipe by chopping the chuck roast into large pieces while it was still whole. 

You may leave the chuck roast whole if it weighs less than 3 pounds and fits in the pot. If not, cut it into big pieces.

The majority of store-bought chuck roast servings weigh about 3 pounds. The cook times for the Instant Pot are shown below, along with the weight of the chuck roast. 

Weight of Chuck Roast with Instant Pot Cooking Times:

  • 3 lbs. – 65 minutes (High Pressure)
  • 70 minutes – 4 pounds (High Pressure)
  • 75 minutes if you weigh 5 pounds (High Pressure)

I turn the instant pot off when the timer goes off and let it alone for another 15 minutes. Then I turn the valve to venting over my kitchen hood using a cloth or wooden spoon.

Beef Roast, Rump Roast, Eye Round Roast, Stew Meat, or Chuck Shoulder were some of the other cuts of beef available. Because we’re boiling it for a long period to break down the tough tissue, any of these “difficult” meats will work.

What’s the best way to serve Mexican Pot Roast?

This delicious and tender Mexican pot roast comes out beautifully. Ropa Vieja is traditionally served with white rice and black beans, which we like. 

Tacos or Burritos—This beef is also delicious in tacos, with cilantro and chopped onion on top. You could make a bigger burrito using the Mexican Pot Roast, rice, and beans.

Salad or Bowls- A taco salad with fresh romaine or iceberg lettuce, sliced tomatoes, onions, cucumbers, and jalapenos for flavor is a wonderful nutritious choice. Cauliflower rice and avocado slices may also be used to create a low-carb dish.

The Mexican Pot Roast may be frozen in an airtight container for up to 3 months and tastes even better the following day.

Instructions 

Instructions for using the Instant Pot:

  • Toss the tomato sauce into the instant pot. Season both sides of the Chuck Roast with salt and pepper before placing it in the Instant Pot. If the Chuck Roast is too large to cover the bottom of the pot in an equal layer, chop it into pieces. 

  • Chili powder, chopped garlic, and sliced onions and bell peppers are equally distributed over the chuck roast. Set the valve to ‘Sealing’ on the Instant Pot’s lid.

  • Cook on high pressure for 3 minutes (3 lbs- 65 minutes, 4 lbs- 70 minutes, 5 lbs- 75 minutes), then naturally release pressure for 15 minutes. When you’re finished, release any residual pressure. 

  • Carefully remove the cover and shred the meat in the saucepan. Stir in the vinegar, or use olives and brine for the vinegar.

  • Serve with black beans and rice (regular or cauliflower for low carb).

Instructions for using the slow cooker are as follows:

  • Except for the vinegar, combine all ingredients in the order listed. Cook for 8 hours on low. Shred the meat in the saucepan after it’s done. Stir in the vinegar, or use olives and brine for the vinegar.

  • Serve with black beans and rice (regular or cauliflower for low carb).

Notes

I’ve never had a burn notice in my Instant Pot, but if you’re worried or receive it often, add 1 cup of water to the 1 cup of tomato sauce before adding the chuck roast.

 

I love Mexican-inspired recipes, so I was excited to learn about the Instant Pot and how it could help me to create delicious and authentic Mexican food.
