In a large mixing bowl, whisk together the eggs, milk, flour, salt, cinnamon, nutmeg, vanilla extract, and sugar until well combined.
Place a non-stick pan or griddle on medium heat and allow it to warm up. You can add a small pat of butter or drizzle of oil.
Dip the thick slices of bread into the egg mixture, coating both sides evenly. Allow excess batter to drip off.
Cook the bread slices for about 3-4 minutes on one side until golden brown. Flip gently and cook for an additional 3-4 minutes.
Transfer the Fluffy French Toast to a serving plate. Top with your favorite toppings such as fruits, whipped cream, or syrup.
