Gather your ingredients. Measure out 2 cups fresh mango chunks (peel and pit fresh mangoes, or use thawed frozen mango), 1 cup Greek yogurt, 1/2 cup whole milk, 1/4 cup honey, 1/2 cup ice, 1/2 teaspoon vanilla, and a pinch of salt. Checkpoint: All ingredients should be at hand and measured before you start blending.
Add mango to blender. Pour 2 cups mango chunks into the blender jar first. This prevents yogurt and milk from sticking to the bottom during blending.
Add yogurt and milk. Scoop 1 cup plain Greek yogurt and pour 1/2 cup whole milk directly into the blender on top of the mango.
Add sweetener and flavorings. Drizzle in 1/4 cup honey (adjust to taste based on mango sweetness), add 1/2 teaspoon vanilla extract, and pinch of sea salt. The salt enhances the mango and yogurt flavors without making it taste salty.
Add ice. Pour 1/2 cup ice cubes into the blender. If using frozen mango instead of fresh, reduce ice to 1/4 cup to avoid overly thin smoothie. Checkpoint: All wet and dry ingredients should now be in the blender.
Blend until completely smooth. Secure the blender lid and blend on high speed for 60–90 seconds. Stop and check texture. If chunks remain, blend for another 30 seconds. You should see no visible mango particles; the smoothie will be thick, creamy, and pourable, not watery or grainy.
Taste and adjust. Pour a small spoonful into a cup. If too thick, add 2 tablespoons milk. If not sweet enough, add 1 more tablespoon honey and blend 10 seconds. If too sweet, add 2 tablespoons milk. Checkpoint: Flavor and texture should match your preference before pouring.
Pour into serving glasses. Divide smoothie evenly between 2–3 tall glasses (depending on how full you want them). Pour immediately while cold and thick.
Garnish and serve immediately. Top each smoothie with a fresh mint leaf, a thin mango slice, or a light sprinkle of chia seeds if desired. Serve with a wide straw or smoothie spoon while temperature is coldest, within 5 minutes of blending.
Optional boost: If using chia seeds, add 1 tablespoon before blending. They will thicken the smoothie slightly and add omega-3s and fiber. If adding protein powder for a post-workout smoothie, add 1/4 to 1/3 cup scoop of vanilla protein and blend an additional 10 seconds until fully incorporated.
