Add the ground beef to a large skillet and start it cooking over medium heat, breaking it up as it cooks.
Add the diced potato and onion to the ground beef once the beef starts to turn brown. Cook the beef and potatoes together for about 5 minutes until the potatoes start to soften.
Spoon off any excess fat, leaving behind about 2 tablespoons of fat, then add the green bell pepper and garlic. Cook an additional 2-3 minutes.
Season the mixture with cumin, salt, and pepper and stir well.
Simmer the Carne Molida on low heat for 10 minutes allowing the flavors to combine.
Mix in the chopped cilantro and squeeze in the lime juice, then serve and enjoy!
Notes
Chef Jenn's Tips
I use 80/20 ground beef and just spoon off the extra fat. This ensures lots of beefy flavor.
You can make this ahead of time and keep it in the fridge for 3-4 days, making it a great choice for meal prepping. It also freezes like a dream!
