This recipe is easy to make. They call it impossible pie because it makes its own crust. Was really doubtful when I fixed it the first time. Have run across many more recipes that are like this and I just love it.
Heat oven to 400 degrees. Grease a 10" pie plate. Sprinkle ham, cheese, and onion in the plate. Beat remaining ingredients until smooth, 15 seconds on high or 1 minute with mixer. Pour into plate over other ingredients. Bake until golden brown and knife inserted in center comes out clean. 35 to 40 minutes. Cool 5 minutes and serve.
