- 1 pie shell (I prefer Pillsbury’s)
- 1 yellow onion, chopped
- 1 lb. asparagus, woody ends broken off
- 3 tbsp unsalted butter
- 3 large eggs
- 1 cup half and half (can use fat-free if you like)
- 3/4 tsp sea salt, finely ground
- ½ tsp pepper, freshly ground
- ¾ cup shredded Gruyere cheese
- ½ cup finely grated Parmesan cheese
Melt your butter in a large skillet and add the chopped onions, sauteing for about 3 minutes. Next add the asparagus pieces and sauté for another 3 minutes. Remove the onions and asparagus from the heat and set aside.
Next, spread the onions and asparagus over the cheese.
Sprinkle the remaining cheese over the asparagus onion mixture.
Now you’re ready to pour the egg and half and half mixture – slowly pour the custard mixture over the top of your cheese, asparagus and onion mixture. If there are any asparagus tips poking out, gently push them down into the custard. Bake on the center rack for 25 to 30 minutes, until the custard is set and the top is golden and slightly puffy.
Slice, serve and enjoy!
