Start by preheating your oven to 350 degrees. This is essential for getting those sliders nice and toasty.
In a large skillet, brown the ground beef and onion together. As they cook, the onion will become translucent and sweet, infusing the beef with flavor. Make sure to break the beef into small pieces so it cooks evenly.
Once the beef is browned, drain the excess fat. You want the meat to be moist, but not greasy.
Next, stir in the Velveeta cheese and the onion soup mix. Cook this mixture over low heat until the cheese melts completely. This should take around five minutes. The result will be a creamy, cheesy filling that’s simply irresistible.
Take your slider rolls and slice them in half horizontally. This creates the perfect little nests for our delicious filling.
Spread the cheesy beef mixture generously on the bottom half of each roll. I find using a cupcake scooper makes this step a breeze!
Carefully place the tops of the rolls over the filling, creating little sandwiches. This is where the magic happens!
Arrange the filled sliders on a baking dish lined with parchment paper. This helps with easy cleanup and prevents sticking.
You can choose to wrap the whole pan in foil or each slider individually. This helps to keep the moisture in as they bake.
Slide the baking dish into your preheated oven and bake for 15 to 20 minutes. You’ll know they’re done when the tops are golden brown and crispy.
Once out of the oven, remove the foil and top each slider with a dill pickle slice. This adds a nice crunch and flavor contrast that ties everything together.
Serve the sliders immediately, optionally with ketchup and mustard on the side for that extra zing!
