Put food on the all-white base (foam, paper or white cloth around it).
To be quite uneven lighting, use a reflector (styrofoam or paper) to reflect light in the window and put it in front of and beside the food.
To get the effect of blur in the back, use the setting aperture f / 4 or larger (f/3.5, f/2.8, … etc.)
Use a tripod to prevent the composition better and sharper results
If you are lucky enough to have 2 pieces of flash lights, play wear light and fill light behind the object in front and besides – could use a fill light reflector with materials as mentioned above
