These pork tenderloin sliders are coated in a maple-mustard glaze and topped with slow-caramelized onions. Ready in 30 minutes, they're simple, flavorful, and perfect for parties or casual family dinners.
Trim the silverskin from the tenderloin, slice it into 1/2-inch medallions, and season them on both sides with salt and pepper.
Heat 1-1/2 tablespoons of oil in a large skillet over medium-high heat. Working in batches and adding more oil if needed, sear the pork medallions until barely browned, about 1-1/2 minutes per side. Transfer to a plate and set aside.
Wipe any remaining oil from the pan, and reduce the heat to medium. Add the butter, maple syrup, and mustard, and stir until the mixture is bubbly and slightly thickened.
Return the pork to the pan. Using tongs, turn each slice in the sauce several times to coat. Add a sprinkle of black pepper and remove from the heat.
While the pork finishes in the sauce, lightly toast the slider buns in the oven until golden.
To assemble, place a pork medallion on each roll and top with caramelized onions. Drizzle with a little extra sauce and serve warm.
Notes
MAKE AHEAD TIPS: Pan-sear the pork and prepare the onions up to a day ahead. Refrigerate separately. When ready to serve, reheat the onions over low heat and warm the pork briefly in the sauce before assembling.
