  • Olives (Optional): Salty, briny olives complement the meaty filling.
  • Sour Cream or Plain Greek Yogurt: The cool, creamy topping balances the robust beef filling.

Tips for the Best Leftover Sloppy Joes Tacos

If you want to make your tacos even more irresistible, follow these tips.

  • Make ‘em crispy. For a crispy taco shell, lightly fry the tortillas in a bit of oil until golden before filling them.
  • Put in some elbow grease. Use freshly grated cheese for the best results. It tastes better and melts more readily than the pre-shredded stuff.
  • Use a slotted spoon. When transferring the Sloppy Joe mixture, use a slotted spoon to prevent excess liquid from making the tacos soggy.
  • Brighten them up. Squeeze a lime wedge over the assembled tacos to brighten the flavors and make them pop.
  • Mix things up! Try other cheeses like queso fresco or pepper jack. Or, serve with a side like black beans, queso dip, roasted veggies, or chips and salsa.
