In a skillet over medium-high heat, warm the olive oil. Add minced garlic and optional red pepper flakes, sautéing for 30-60 seconds until the aroma is released.
Place the broccoli florets into the skillet, seasoning with salt and pepper. Pour in the water or chicken broth, then cover the skillet. Let it cook for 3 minutes.
Uncover the skillet and continue cooking the broccoli for 2-3 minutes, or until the water has fully evaporated and the edges of the broccoli start to brown.
