This hearty and flavorful frittata is a perfect breakfast or brunch dish. Start by sautéing chopped asparagus and bacon in a cast-iron skillet until they are tender and lightly browned. Whisk together eggs, cream, and grated Parmesan cheese, then pour the mixture over the asparagus and bacon in the skillet. Bake until the frittata is set and the top is golden brown.
