Ingredients
- Leftover Sloppy Joe Filling: The main filling for these hearty ground beef tacos.
- Taco Shells or Tortillas: Crispy shells, corn tortillas, or soft flour tortillas all work. Pick your favorite!
- Cheddar or Monterey Jack Cheese: Shredded cheese melts beautifully over the warm filling. Cheddar adds more bite, while Monterey Jack is more creamy.
- Lettuce, Tomatoes, and Red Onion: Classic taco fillings add freshness, flavor, and texture.
- Olives (Optional): Salty, briny olives complement the meaty filling.
- Sour Cream or Plain Greek Yogurt: The cool, creamy topping balances the robust beef filling.
- Avocado (Optional): Creamy avocado takes things up a notch. Add slices or mash it into a quick guacamole.
- Fresh Cilantro: Sprinkle it on top for a burst of freshness.
How to Make Leftover Sloppy Joes Tacos

- Add the toppings:
- Try a dollop of sour cream, sliced avocado, and a sprinkle of fresh cilantro.
- Serve the tacos:
- Serve warm, and enjoy.

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.

How to Store
Here’s how to keep your leftovers fresh.
- To Store: Place the leftover mixture and toppings in separate air-tight containers. Refrigerate for up to 3-4 days.
- To Freeze: Transfer the cooled mixture to a freezer-safe container or bag. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- To Reheat: Reheat the mixture in a skillet over medium-low heat, stirring frequently until warmed through. Add a splash of water if needed. Or, microwave in short intervals, stirring between each, until heated.
