This pork tenderloin recipe already comes with its own side of apples and onions, so you don't need to add much to make it a complete meal! Try pairing the pork tenderloin with a starch such as rice, crusty bread, and/or roasted potatoes (my recipe for air fryer fingerling potatoes would work great). Bonus points for drizzling the gravy overtop the potatoes as well! A green salad would also pair nicely, adding a fresh and crunchy element. Dutch oven pork tenderloin would also go well with my recipes for roasted brussels sprouts and carrots and lemon herb roasted asparagus.
