Slow Cooker Root Beer Sloppy Joe Sliders Recipe Tips

  • Use full-flavored root beer (not diet) for the best sweet and tangy taste.
  • Browning the ground beef before adding it to the slow cooker enhances flavor and texture.
  • Stir the sauce well to coat all the meat and vegetables evenly.
  • Adjust seasoning to taste, add more salt, pepper, or mustard if desired.
  • For thicker Sloppy Joes, cook uncovered for the last 30 minutes to reduce excess liquid.
  • Optional toppings like cheddar cheese or pickles add extra flavor and texture.

Storing Instructions

Store leftover Sloppy Joe mixture in an airtight container in the refrigerator for up to 4 days. Reheat in a skillet over medium heat or in the microwave, adding a splash of root beer or ketchup if the mixture is too thick. Keep slider buns stored separately and warm just before serving.

Slow Cooker Root Beer Sloppy Joe Sliders Recipe Faqs

Can I use a different type of soda? Yes, you can substitute another sweet, carbonated soda like cola or cream soda, though root beer gives the best sweet-tangy flavor.

Can I make this with ground turkey or chicken? Absolutely! Ground turkey or chicken works well; adjust cooking time slightly and ensure it’s fully cooked.

Can I prepare this ahead of time? Yes, assemble the ingredients in the slow cooker the night before and refrigerate. Cook the next day, adding about 30 extra minutes if needed.

Can I freeze leftovers? Yes, store cooled Sloppy Joe mixture in an airtight container in the freezer for up to 3 months. Thaw in the refrigerator before reheating.

How can I thicken the sauce if it’s too runny? Stir in a small amount of quick-cooking oatmeal, cornstarch, or cook uncovered for the last 30 minutes to reduce excess liquid.

Can I make this on the stovetop instead of a slow cooker? Yes, cook the beef, vegetables, and sauce in a large skillet over medium heat, simmering until thickened and fully cooked.

What can I serve with these sliders? They’re perfect on slider buns, sandwich rolls, or even over rice or mashed potatoes for a hearty meal.
