To prepare a vegetarian beetloaf recipe, you will first need to prepare your ingredients. You will need: Beets: Peel, cut, and shred. Parsley: Finely chop the parsley and add it to the bowl with the thyme. Salt and pepper to taste. Brown the ground beef in the olive oil. Add the chopped onions and cook until the onions are translucent, about 5 minutes. Then add the flour and mix until it's just combined. Pour the dry ingredients into the wet ingredients and stir until they're evenly coated. Cook the mixture over medium heat, stirring constantly, until thickened. Remove the pan from the heat and set aside to cool.
