Heat the oven to 350 degrees F. Prepare the sausage and mushrooms as directed in the ingredient list. Let them cool slightly before proceeding with the recipe (they can be warm when added to the eggs, but not piping hot).
In a bowl, whisk the eggs with the half-and-half, flour (don't worry if the flour forms small lumps), salt, and several grinds of pepper.
Combine the sausage, mushrooms, Pecorino, basil, and garlic with the egg mixture, folding them in gently.
Heat the olive oil in a 10-inch ovenproof anodized aluminum or nonstick skillet over medium heat. When the oil is hot, add the egg mixture, spreading everything evenly. Reduce the heat to low, cover, and cook until the eggs are set about 1 inch in from the sides of the pan, 8 to 12 minutes.
Uncover the pan and transfer the frittata to the oven. Bake until the top is puffed and completely set, 15 to 25 minutes more.
Remove the pan from the oven and run a rubber spatula around the sides of the pan to loosen the frittata. Slip it out of the pan and onto a cutting board. Let the frittata cool for 10 minutes before cutting and serving. Or let it cool completely to room temperature.
