Instructions

Step 1

Begin by preparing your slow cooker. If you have a 6-quart model, that’s perfect; a 4-quart will also work. Place the ground beef and chicken pieces directly into the slow cooker. There’s no need to brown the meat first—this saves time and allows the flavors to meld during the long, slow cooking process. The chicken will become incredibly tender and shred easily, while the ground beef will cook through and absorb all the seasoned liquid. Sprinkle the entire packet of taco seasoning evenly over the meat. Pour in the water or chicken broth—this helps create a flavorful cooking liquid that keeps the meat moist and helps the seasoning distribute evenly. Use a spoon or spatula to gently toss the meat with the seasoning and liquid, making sure everything is coated. Cover the slow cooker with its lid and set it to cook on LOW for 4 hours. If you’re short on time, you can cook on HIGH for 2 hours, but the low-and-slow method yields more tender, flavorful results. The meat is ready when the chicken reaches an internal temperature of 165°F (74°C) and shreds easily with a fork, and the ground beef is fully cooked and no longer pink.

Step 2

While the meat cooks, prepare your toppings. This is where you can get creative and set up a taco bar that everyone will love. Start by dicing the white onion into small, uniform pieces—about 1/4-inch dice. The sharpness of raw onion adds a beautiful crunch and bite that contrasts with the rich meat. Chop the cilantro finely, including the tender stems for extra flavor. If you’re making guacamole, mash 2 ripe avocados with a fork, then stir in 1 tablespoon of lime juice, 1/4 cup of diced tomato, 2 tablespoons of finely chopped onion, 1 tablespoon of chopped cilantro, and salt to taste. For a quick pico de gallo, combine 1 cup of diced tomatoes, 1/4 cup of diced onion, 2 tablespoons of chopped cilantro, 1 tablespoon of lime juice, and a pinch of salt. You can also prepare sour cream (or use Greek yogurt for a protein boost), shred some cheese (cotija or Monterey Jack are great), and cut lime wedges. Keep all toppings refrigerated until serving.

Step 3

When the cooking time is up, carefully remove the lid—watch out for the steam. Using tongs, transfer the chicken pieces to a cutting board. Let them rest for a few minutes until cool enough to handle. Then, using two forks, shred the chicken into bite-sized pieces. The meat should pull apart effortlessly; if it resists, it might need a bit more cooking time. Return the shredded chicken to the slow cooker with the ground beef. Give everything a good stir to combine the two meats and coat them in the seasoned juices. Taste the meat and adjust seasoning if needed—you might want a pinch of salt or an extra sprinkle of cumin. If the mixture seems too wet, you can leave the lid off for 10-15 minutes to let some liquid evaporate. The final texture should be moist but not soupy.

Step 4

Now it’s time to warm the tortillas. This step is crucial for authentic street tacos. Heat a dry skillet or griddle over medium-high heat. Working one at a time, place a corn tortilla in the hot skillet for about 30 seconds per side. You’ll see it puff up slightly and develop brown spots—that’s the char that adds smoky flavor. Alternatively, you can wrap a stack of tortillas in foil and warm them in a 350°F (175°C) oven for 10-15 minutes. The goal is pliable, warm tortillas that won’t crack when folded. Keep them covered with a clean kitchen towel to stay warm while you prepare the tacos.

Step 5

To assemble the tacos, place a warm tortilla on a plate or in your hand. Spoon about 2-3 tablespoons of the meat mixture into the center. Don’t overfill—street tacos are meant to be modest in size, allowing the flavors of the toppings to shine. Top with a sprinkle of diced onion and fresh cilantro. Add a dollop of sour cream, a spoonful of guacamole, and some pico de gallo if desired. Finish with a squeeze of fresh lime juice—the acidity brightens all the flavors. Serve immediately while the tortillas are still warm and the meat is hot. These tacos are best enjoyed fresh, but you can keep the meat warm in the slow cooker on the ‘keep warm’ setting for up to 2 hours.

For best results

  • For the most tender chicken, use boneless skinless thighs instead of breasts. Thighs have a higher fat content, which keeps them juicy during the long slow cook. If you prefer white meat, be careful not to overcook—check for doneness at 3 hours on low. The ground beef should be at least 85% lean; anything leaner may become dry. You can also substitute ground turkey or pork for a different flavor profile. If you want a thicker, more caramelized texture, you can brown the ground beef in a skillet before adding it to the slow cooker, but this step is optional and adds about 10 minutes to prep time.
  • Homemade taco seasoning is easy to make and lets you control the sodium and spice level. Combine 1 tablespoon chili powder, 1 teaspoon cumin, 1 teaspoon smoked paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon oregano, 1/4 teaspoon cayenne (optional), and 1 teaspoon salt. This equals about one packet. Store extras in an airtight jar for up to 6 months. Using homemade seasoning also allows you to adjust the heat—add more cayenne for a kick or reduce it for a milder family-friendly version.
  • To keep the tortillas from getting soggy, warm them just before serving and don't let the meat sit on them for too long before eating. If you're making a batch for a party, set up a taco bar where guests can assemble their own tacos. This way, the tortillas stay fresh and the meat stays hot in the slow cooker. You can also double the meat recipe and freeze half for later—the cooked meat freezes beautifully for up to 3 months. Thaw overnight in the fridge and reheat in a skillet or microwave.
  • For a smoky, charred flavor, you can char the tortillas directly over a gas flame using tongs. Hold each tortilla over the flame for about 15-20 seconds per side, watching closely so they don't burn. This method gives an authentic street taco taste that can't be beat. If you don't have a gas stove, a hot cast-iron skillet works well too. Just make sure the skillet is screaming hot before adding the tortilla.
  • Leftover meat can be repurposed in so many ways: use it as a filling for burritos, nachos, quesadillas, or taco salads. You can also mix it with scrambled eggs for a delicious breakfast hash. Store leftover meat in an airtight container in the refrigerator for up to 4 days. Reheat gently in a skillet with a splash of water or broth to restore moisture. The meat also freezes well—portion it into freezer bags and flatten for easy storage. Thaw in the fridge overnight before reheating.
  • If you want to add more vegetables to the slow cooker, consider adding diced bell peppers and onions during the last 30 minutes of cooking. They'll soften but still retain some texture. You can also stir in a can of drained and rinsed black beans or corn kernels for extra fiber and sweetness. Just be aware that adding too many veggies may dilute the seasoning, so you might need to adjust the spices accordingly.

Variations

  • For a vegetarian version, replace the meat with 2 cans (15 oz each) of black beans or pinto beans, drained and rinsed, plus 1 cup of frozen corn. Add the beans and corn to the slow cooker with the taco seasoning and 1/2 cup of vegetable broth. Cook on low for 2-3 hours until heated through. The beans will absorb the seasoning and become creamy. You can also add diced bell peppers, onions, and zucchini for more texture. Serve with all the same toppings—the result is a hearty, protein-packed vegetarian taco that even meat-lovers will enjoy.
  • For a spicy chipotle twist, add 2-3 chipotle peppers in adobo sauce (minced) along with the taco seasoning. This will give the meat a smoky, deep heat that pairs beautifully with a cooling crema made from sour cream and lime. You can also stir in a tablespoon of adobo sauce for extra flavor. If you're sensitive to spice, start with one pepper and taste before adding more. The chipotle adds complexity that elevates the dish from simple to extraordinary.
  • For a keto or low-carb option, skip the corn tortillas and serve the meat over lettuce wraps, in bell pepper halves, or on a bed of cauliflower rice. The meat itself is low-carb (especially if you use homemade seasoning without sugar), so it fits perfectly into a keto lifestyle. Top with cheese, avocado, sour cream, and salsa—just avoid tortillas and beans. You can also use the meat to make a taco salad: layer lettuce, meat, cheese, tomatoes, avocado, and a drizzle of ranch or chipotle dressing.
  • For a breakfast taco variation, use the leftover meat to fill warm tortillas and top with scrambled eggs, shredded cheese, and salsa. This makes a fantastic high-protein breakfast or brunch that comes together in minutes. You can also add crispy bacon or chorizo for extra indulgence. Breakfast tacos are a Texas tradition and a great way to repurpose leftovers in a creative way.

Common Questions

Can I use only ground beef or only chicken?
Absolutely! This recipe is designed to be flexible. If you want all beef, use 2 pounds of ground beef (or a mix of ground beef and ground pork). For all chicken, use 2 pounds of boneless chicken thighs or breasts. The cooking time remains the same. Just make sure the meat is fully cooked to safe internal temperatures: 160°F for beef, 165°F for chicken. Using a mix of meats adds variety in texture and flavor, but a single meat works just as well.
How do I store leftovers and how long do they last?
Store leftover meat in an airtight container in the refrigerator for up to 4 days. To reheat, place the meat in a skillet over medium heat with a splash of water or broth to prevent drying. Stir occasionally until heated through, about 5 minutes. You can also microwave it in a covered dish for 2-3 minutes. The meat can be frozen for up to 3 months—thaw overnight in the fridge before reheating. Tortillas and fresh toppings should be stored separately and assembled just before eating to maintain quality.
Can I make this recipe in an Instant Pot or pressure cooker?
Yes, you can adapt this recipe for an Instant Pot. Use the sauté function to brown the ground beef first (optional), then add the chicken, seasoning, and 1/2 cup broth. Pressure cook on high for 10 minutes (for chicken thighs) or 12 minutes (for chicken breasts) with a natural release of 10 minutes. Shred the chicken and stir with the beef. The total time is much shorter, but the slow cooker version allows for more hands-off cooking and deeper flavor development. Both methods yield delicious results.
What can I use instead of taco seasoning?
If you don’t have taco seasoning, you can make your own with common pantry spices. Mix 1 tablespoon chili powder, 1 teaspoon ground cumin, 1 teaspoon smoked paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon dried oregano, 1/4 teaspoon cayenne (optional), and 1 teaspoon salt. This blend closely mimics the flavor of store-bought packets. You can also use a combination of cumin, chili powder, and garlic powder as a base; adjust to taste. If you want a more authentic Mexican flavor, add a pinch of ground coriander and a teaspoon of dried Mexican oregano.
Are these tacos gluten-free?
Yes, as written this recipe is naturally gluten-free. Corn tortillas are typically gluten-free, but always check the package to ensure they are made from 100% corn and not a blend with wheat flour. The taco seasoning should also be checked—some brands may contain wheat flour as a filler. To be safe, use homemade seasoning or a certified gluten-free brand. All other ingredients (meat, vegetables, toppings) are naturally gluten-free. Serve with corn tortillas and enjoy!
Can I prepare the meat ahead of time for a party?
Definitely! The meat can be cooked up to 2 days in advance. After cooking, let it cool completely, then store it in the refrigerator in an airtight container. On the day of your party, reheat the meat in the slow cooker on low for 1-2 hours, adding a little water or broth if needed to restore moisture. You can also keep it warm in the slow cooker on the ‘keep warm’ setting for up to 2 hours. This makes party prep a breeze—just set out warm tortillas and toppings, and let guests build their own tacos.
