Happy Cooks Speak Up

“The soup is delightfully flavored and so simple , thank you.”CAROL

Is This Stew the Same as Posole?

Yes, they are essentially the same. Posole (aka”pozole”) is traditionally made with pork, but sometimes chicken is substituted. Posole always contains hominy, just like this recipe.

Do You Want To Cook This Recipe in Your Instant Pot?

I’m a gadget person who likes things to happen fast. That’s why I’m in love with my Instant Pot(paid link).

If you are new to this type of cooking, be warned that it takes longer than 7 minutes (the amount of time you set on the timer) to cook the soup. First, the pot must reach a certain pressure level before the timer kicks in. How much time this process takes depends on the temperature of the ingredients when you put the lid on.

How Can I Speed Up the Process When Using an Instant Pot?

Heat all liquids before adding them to the Instant Pot when you need dinner on the table as fast as possible. Pop them into the microwave.

Also, avoid putting any frozen ingredients into your cooker. You don’t HAVE to do this, it’s just a shortcut for helping your Instant Pot get up to pressure faster. This will hasten the cooking of your food under full pressure.

Directions for Making This Leftover Pork Roast Recipe on Top of the Stove

Don’t feel left out if you don’t have a pressure cooker of some kind. First, follow step 1 using a large pot on top of the stove. Like step 2, add the remaining ingredients and simmer for 30-40 minutes.

You could also make this in a slow cooker and let it cook all day, but I would only do that if it’s convenient since long cooking is not really necessary.

FAQ About Leftover Pork Roast

  • 2-3 (122 g) carrots, finely diced
  • 1 tablespoon fresh garlic, minced
  • 1 15-1/2 ounce can (440 g) hominy, drained
  • 4 cups (908 g) chicken broth
  • 1 14-1/2 ounce (411 g) can fire-roasted diced tomatoes or substitute regular diced tomatoes

  • ½ teaspoon fresh oregano finely chopped (or substitute 1/4 teaspoon dried)
  • 1 tablespoon chili powder
  • 1 teaspoon ground cumin
  • ½ teaspoon salt
  • ½ teaspoon freshly ground pepper
  • 2 teaspoons fresh cilantro, chopped


  • Press the Sauté button and allow to preheat until it says HOT. Add 2 tablespoons vegetable oil and 1 (110 g) medium onion, finely diced and cook for about 3-4 minutes, stirring frequently until onions are softened.
  • Add 1 (40 g) stalk celery, finely diced, 2-3 (122 g) carrots, finely diced, 1 tablespoon fresh garlic, minced ,1 15-1/2 ounce can hominy, drained ,4 cups (908 g) chicken broth ,1 14-1/2 ounce (411 g) can fire-roasted diced tomatoes2-3 cups (270-405 g) roast pork, diced, 1/2 teaspoon fresh oregano, 1 tablespoon chili powder, 1 teaspoon ground cumin, 1/2 teaspoon salt, and 1/2 teaspoon freshly ground pepper to Instant Pot and stir to combine. Place the lid on and close the pressure valve. Press the “Manual” button and then adjust the time by using the + or – button to set it for 7 minutes on HIGH Pressure.
  • When finished, use a quick release. Alternatively, allow pot to lose pressure naturally (do nothing) and it will automatically keep your soup warm until you are ready to eat.
  • Add 2 teaspoons fresh cilantro, chopped when serving.


If you don’t have a pressure cooker, follow steps 1-3 in a large pot on top of the stove. Instead of step 4, you will add all the ingredients to the pot and and simmer for about 30-40 minutes.
If you are really in a hurry, heat the broth in the microwave while you are cooking the vegetables so that Instant Pot will come to full pressure faster.

    1. The soup is delightfully flavored and so simple , thank you. It would be good to have the on the stove recipe to print for me and many others. I understand the instapots are very helpful but I like to cook on my stove top, step by step. I do not need another appliance.

      1. Hi Carol,

        The stove top directions are in the notes of the recipe. The notes will print out on the bottom of the recipe. Hope that helps.
