Preheat oven to 350 degrees F.
In a large bowl, crack eggs and whisk in half and half, 1/2 teaspoon each of salt and pepper, and goat cheese. Set aside.
Heat roughly two tablespoons of olive oil in an oven-safe 10" non-stick skillet. Add shallot and sauté for a few minutes until translucent. Add asparagus and continue to sauté another few minutes until cooked through.
Remove skillet from heat. Pour in egg mixture with sautéed vegetables. Stir slightly to evenly distribute the asparagus and shallot.
Place skillet into oven and bake about 20 minutes until the center of the frittata is set but not browned.
Top with things like microgreens, fresh herbs, more goat cheese, flakey sea salt, a drizzle of olive oil, freshly cracked black pepper, and sliced radish if desired.
