Shredded Beef Tacos that are Full of Flavor

The best, shredded beef taco is inspired by your favorite, down-home dinner recipe.

But this isn’t your typical Beef Roast recipe. Instead of the traditional carrots, potatoes, and gravy, we’re slow cooking the beef with taco seasonings, peppers, and lime for some mega delicious tacos!

Serrano and jalapeno peppers are used to give the meat a kick of heat and extra flavor. If heat isn’t your thing, don’t worry, leave them out and carry on with the recipe. The tacos will still be UH-MAZING!

How to Make Slow Cooker Beef

Like all slow cooker recipes, this one involves minimal effort for a delicious meal. Set the roast in the slow cooker dish, top with the veggies, peppers, and seasonings and cook on low for 8 to 10 hours for the perfect, tender, fall apart roast.

If you’re pressed for time, you can also cook it on high for 4 to 6 hours but I always get the best results when I let beef, pork, and chicken cook low and slow. It gives the meat time to cook and soak in its own juices.

What to Put on Tacos

I’m sure all of us here are professional taco eaters, and if you’ve been following the Taco Tuesday series on my YouTube Channel, you know the elements of the perfect taco:

  • Tortilla
  • Meat or Vegetarian option (eggs, beans, mushrooms etc.)
  • Veggies
  • Cheese
  • Sauce

Once you have the meat down, it’s time to choose how you’ll top your taco and there are A TON of incredible options like:

  • Cotija cheese, shredded cheese, Goat cheese, feta
  • Fresh salsa
  • Pico de Gallo
  • Sour Cream
  • Guacamole
  • Avocado
  • Lettuce
  • Sauteed peppers and onions
  • Black Olives

For these Slow Cooker Shredded Roast Beef Tacos I chose shredded Cheddar cheese, avocado, and fresh pico de gallo. The pico gives these beef tacos a refreshing element while the cheese does it’s thing and gets all melted and gooey.

You’ll notice this recipe doesn’t have a sauce, but that because the juice from the roasted beef is a sauce all on its own!

If you like a little more oomph! in your tacos, the Taco Tuesday Cookbook has you covered with ideas like roasted peppers and onions, Curried Cauliflower, a fried egg, Cilantro Lime Dressing, Pineapple Salsa, Cilantro Chimichurri, Sriracha Lime Dressing, Thai Peanut Sauce – we definitely kick Tuesdays up a notch.
