What is Cadillo?
Caldillo, or Mexican Green Chile Steak Soup is a hearty soup recipe.
It’s really more of a stew with hearty strips of London Broil, potatoes, and rich smoldering spices of cumin, chili powder and garlic.
Mexican Steak Soup Ingredients
- London Broil steak or Sirloin steak
- Olive Oil
- White Distilled Vinegar
- All-Purpose Flour (regular or gluten-free)
- Garlic Powder
- ground Cumin
- ground Black Pepper
- ground Chipotle Chile Powder (regular chili powder may be substituted)
- Beef Stock
- Yellow Onion
- canned Diced Tomatoes
- canned Mild Green Chilies
London Broil steak
London Broil is used in this steak soup.
It’s the top pick for the flavor, texture and that it would tenderize as the soup simmered for a few hours.
It is an affordable cut of meat and comes from the same area where Round Steak originates.
It does not contain much marbling or fat.
My butcher pointed out that due to its appearance people often mistake it for the type of steak to be grilled and served as a whole individual steak.
This does not favor the best qualities of London Broil.
It is perfect for longer cooking and should always be sliced across the grain.
If London Broil is not available, Sirloin Steak can be substituted.
Regular all-purpose flour may be used or a gluten-free flour blend.
The purpose of the flour is to help the spices stick to the steak and add slight thickening to the soup.
This recipe calls for Chipotle Chile Powder. This specific type of chili powder adds an earthy, smoky flavor along with spiciness.
Chipotle chile powder should be available in most spice sections at the grocery store or online.
If unavailable regular chili powder may be substituted.
Using canned green chilies saves time and they are also already cooked giving the best flavor.
The original recipe calls for using canned roasted whole green chilies, sliced lengthwise.
TIME SAVING TIP: I have also used diced Mild Green Chilies. The flavor is the same and there is no preparation involved!
How to Make Mexican Steak Soup – Step-by-Step
Detailed instructions can be found at the end of the blog post in the printable recipe card.
Instructions to make Cadillo on the stove top, in an Instant Pot and slow cooker are included.
Preparation Methods & Tools
The recipe step photos below are made in the Instant Pot. A 6-quart Instant Pot was used to develop this recipe.
The steps are the same if making the spicy soup in a Dutch oven on the stove.
STEP 1: In a small mixing bowl combine the flour, garlic powder, cumin and pepper (photo 1). Mix together.
STEP 2: Place the sliced steak in a large mixing bowl and pour the vinegar onto the steak. Massage vinegar into the steak with your hands (photo 2).
STEP 3: Sprinkle the flour-spice mixture onto the steak and toss with hands to fully coat the steak. None of the flour mixture should be remaining in the bowl (photo 3).
STEP 4: (For the Instant Pot): Turn on the Saute function and add the olive oil to the Instant Pot insert (photo 4). (For Stovetop) Heat a large Dutch oven over medium-high heat and add the olive oil.
STEP 5: Add the steak and brown lightly (5-7 minutes) (photo 5).
STEP 6: INSTANT POT ONLY: Remove the steak from the Instant Pot. With the Instant Pot still on SAUTE mode, pour in the beef broth. Scrap the bottom of the Instant Pot insert to dislodge any food particles that are sticking (photo 6). This is called deglazing the pan and ensures there will not be a burn warning when cooking the soup.
STEP 7: Add the remaining ingredients: chili powder, onion, diced tomatoes, green chilies, potatoes (and the beef broth if cooking on the stove top). Add the steak back to the Instant Pot (photo 7).
For the Instant Pot: Secure the lid and venting to closed, cook on the SOUP function for 40 minutes. Allow a 10 minute natural release then release any remaining pressure manually.
For Stovetop: Bring to a low boil, lower the temperature so the soup is simmering. Simmer 1-2 hours until the potatoes and meat are cooking.
Topping and Serving Steak Soup
Grated cheddar cheese, torn cilantro or a dollop of sour cream are all great choices for topping this spicy steak soup.
NOTE: dairy products mute the heat from spicy ingredients.
Adding sour cream for anyone that doesn’t love much spicy heat is a great strategy!
Serve with this delicious Cornbread recipe.
Can this steak soup recipe be made in the slow cooker?
Yes it can but from our testing we feel the results are not as good as when cooking it on the stove top or in the Instant Pot.
The meat does not retain the same flavor as with the preferred two methods.
To make it in the slow cooker:
- Follow the instructions under For All Cooking Methods in the recipe card below.
- Perform steps 1 and 2 under the Stove Top method in the recipe card.
- Add the steak to the slow cooker (a 6 quart slow cooker recommended) followed by the remaining recipe ingredient; stir to combine.
- Cook on LOW for 7-8 hours until the potatoes are completely cooked and the meat is soft.
How to Store Leftover Soup
In the Refrigerator
Store leftover soup in airtight containers in the refrigerator for up to 3-5 days.
In the Freezer
Allow soup to cool.
Place in a freezer-safe airtight container leaving 3/4-inch head space for expansion.
Head space is the room above the surface of the soup and the top of the container.
NOTE: adding too much head space risks ice crystals forming on the soup which will affect the flavor.
Store for up to 6 months.
Thaw in the refrigerator or microwave and heat to taste.
NOTE: soup can be frozen in individual serving size containers following the directions above.
