In a small bowl, combine the sliced strawberries, granulated sugar, and lemon juice. Toss to coat and let sit for about 10 minutes to macerate.
In a shallow dish, whisk together the eggs, milk, vanilla extract, and ground cinnamon until well combined.
Heat a large skillet or griddle over medium heat and add the butter, allowing it to melt and coat the surface.
Dip each slice of bread into the egg mixture, ensuring both sides are well coated. Place the dipped bread onto the skillet and cook for about 2-3 minutes on each side, or until golden brown.
Once the French toast is cooked, remove it from the skillet and top with the macerated strawberries. Dust with powdered sugar if desired.
Serve immediately while warm.
