Add the butter and olive oil to a non-stick skillet or pan. Once melted, add the sliced garlic, then the broccolini, and sauté them for 7-8 minutes, adding a few spoonfuls of water halfway through to prevent burning, if needed.
Remove from the heat and serve with sliced lemon and a sprinkle of red pepper flakes.
Notes
TO STORE: Store leftovers in an airtight container in the fridge for up to 4 days. TO REHEAT: Reheat broccolini in the microwave at 30-second intervals until heated through or you can reheat it on the stove over medium heat.
