Make Ahead Tip: Prepare and stuff potatoes. Cover and refrigerate for up to 2 days. Microwave and serve.
Vegetarian variation: Replace the ground beef with a soy-based substitute or omit the beef altogether and increase the broccoli to 1 1/2 cups and the cheese to 1 1/4 cups.
No microwave? No problem: Preheat oven to 400°F. Pierce potatoes in several places with a fork. Bake directly on the center rack until tender, 45 to 60 minutes. Fill the potato as directed and bake the stuffed potatoes on a foil-lined baking sheet until the filling is hot, about 15 minutes.
