Loose meat sliders featuring finely crumbled, seasoned ground beef cooked tender and piled onto homemade slider rolls, finished with yellow mustard, diced onion, and pickle chips in the style of a classic Midwestern sandwich.
Add baking soda and water to a small bowl and whisk until dissolved.
Add the mixture to the ground beef and mix until just combined. Set aside for 15 minutes.
Set aside 1/3 cup diced onion for topping. Heat olive oil in a skillet over medium heat, add remaining onion and 1/4 tsp salt, and cook until softened.
Add the beef to the skillet along with pepper, onion powder, and salt to taste. Cook, breaking it into small crumbles, until fully browned.
Discard most of the fat from the skillet.
Stir in ketchup, yellow mustard, and Worcestershire sauce. Cook until the liquid is absorbed.
Spoon the meat onto slider rolls and top with yellow mustard, reserved diced onion, and pickle chips.
Notes
Do not skip the baking soda: This step helps keep the ground beef tender and loose rather than dense as it cooks.
Do not overmix the beef: Mix just until combined to avoid compacting the meat and changing the final texture.
Drain fat carefully: Leave a small amount in the pan to keep the meat from drying out while preventing a greasy finish.
Cook sauce until absorbed: The mixture should be moist but not wet before serving to maintain the correct texture.
Toppings not included in nutrition: Yellow mustard and pickle chips used for topping are not included in nutritional calculations.
