Preheat at the oven to 400℉. Lightly grease a 10" quiche pan.
Sprinkle the crumbled bacon on the bottom of the quiche pan. Then add the shredded Swiss cheese, diced onion, and asparagus pieces.
In a large bowl, beat the eggs with a fork. Add in the salt, pepper, and milk. Then stir in the Bisquick and stir until very, very smooth.
Pour the egg mixture over the cheese and veggies. Sprinkle paprika over the top. Bake for 35 minutes until the edges are set and a toothpick inserted into the center of the quiche comes out clean. Cool on a baking rack for 15 minutes to set the quiche. Serve immediately.
