Mince beef round into small pieces, roughly 1/4″ cubes
Heat a large sauté pan to medium high heat
Add oil
In batches, sauté the beef until the surface is well caramelized, stirring occasionally
When each batch is done, add to slow cooker
Vegetables
Add more oil and onions to the pan. Sauté until soft and golden. This will deglaze the pan, rescuing all of the tasty bits.
When the onion is close to done, add the jalapenos and sauté until they are softened
Add the garlic and sauté for just a minute or two to release the fragrance
Transfer the onion mixture to the slow cooker
Spices
Add the spice blend to the slow cooker
Add enough water to almost cover the contents
Cooking
Cook the mixture on low for about 5 hours or more. This will make the meat very tender and flavorful
If in a hurry, it can be cooked on high for a shorter time
If the mixture is too moist, partially remove the slow cooker cover and cook on high until obtaining the desired consistency.
Recipe Notes
This could also be cooked in the oven on low heat in a small stock pot I like Muir Glen tomatoes I used olive oil for sautéing the meat and veges. Any oil will do.
