You’ll start this recipe by preheating the oven to 350 degrees.
.Using a small skillet, add the beef and onions to the skillet and cook them until the meat shows no pink and breaks apart easily. You’ll drain the excess liquids.
At that point, you’ll be adding in the taco seasoning and water. Be sure to stir it in well and bring the water to a boil. Afterward, bring down the heat, let the mixture sit uncovered, and wait for 5 minutes.
Once you’re done waiting, remove the mixture from the skillet and add ½ cup of cheese.
For the tart shells, lay them in an ungreased baking pan, about 15 by 10 by 1 inch. You’ll add the taco mixture by laying it in the shells.
Bake these for 6 minutes and add however much cheese you’d like. Once the cheese is melted to your satisfaction it’s done.
Let the dish cool for a bit and serve!
