High-Protein Smoothie Without Protein Powder

Before you start

You do not need powder for a filling, protein-rich smoothie. Strained Greek yogurt is the anchor: it is thick, tangy and carries far more protein per spoon than regular yogurt. Milk adds more and makes it drinkable, while peanut butter and hemp seeds contribute both protein and the richness that keeps a smoothie from tasting thin. With typical label values for plain Greek yogurt and dairy milk, this build comes out above 20 g of protein per glass; check your own labels, since brands vary widely.

Because there is no powder thickening it, frozen fruit does that job. Frozen berries and half a frozen banana give body without ice, which would dilute both flavor and protein. Taste before adding sweetener: Greek yogurt is tart, and a ripe banana is often enough.

Ingredients

• 200 g (¾ cup) plain Greek yogurt — 2% or whole milk, strained style
• 180 ml (6 oz) dairy milk — or ultra-filtered milk for more protein
• 120 g (1 cup) frozen mixed berries
• ½ (about 60 g) frozen banana — sliced before freezing
• 1 tbsp (16 g) natural peanut butter
• 2 tbsp (about 20 g) hemp hearts — shelled hemp seeds
• 1 to 2 tsp honey or maple syrup — optional
• 1 pinch cinnamon — optional

Method

1. Pour the milk into the blender first so the blade has liquid to grip. Add the Greek yogurt and peanut butter next.
2. Add the hemp hearts and cinnamon, then the frozen berries and banana on top.
3. Blend on low for 10 seconds to break up the fruit, then on high for 40 to 60 seconds, until the smoothie is completely smooth and no seed bits or berry skins are visible.
4. Taste and adjust. Add honey if it is too tart, or a splash more milk if it is too thick to pour. Blend for a few seconds after each change.
5. Pour into a glass and drink right away while it is thick and cold.

Tips for success

• To total the protein yourself, add up the grams per serving on each label for the amounts you actually use. Yogurt and milk do most of the work.
• Freeze ripe banana slices flat on a tray, then bag them. They blend into a creamy base far better than a whole frozen banana.
• If you are sensitive to tartness, choose a milder whole-milk Greek yogurt rather than nonfat, which tastes sharper.

Substitutions

Greek yogurt

Skyr is similar in protein and slightly milder. Blended cottage cheese also works and adds a light saltiness. Regular yogurt makes a thinner smoothie with noticeably less protein.

Dairy milk

Soy milk is the closest plant milk for protein. Almond and oat milks are much lower in protein, so the total will drop.

Peanut butter

Almond butter or sunflower seed butter work one-for-one. Sunflower seed butter is a peanut-free option.

Hemp hearts

Chia seeds or ground flaxseed add body and fiber but will thicken the smoothie as it sits, so drink it promptly.

Variations

Chocolate peanut butter

Replace the berries with a whole frozen banana and add 1 tbsp unsweetened cocoa powder.

Green version

Add a handful of spinach and swap berries for frozen mango.

Troubleshooting

It is too sour

Greek yogurt is tangy. Add half a banana more, a teaspoon of honey, or use a whole-milk yogurt next time.

It is too thick to blend

Add milk 2 tablespoons at a time and use the tamper or a spatula between pulses.

There are gritty bits

Hemp or berry seeds were not fully broken. Blend 30 seconds longer, or switch to a smaller blender jar that keeps ingredients near the blade.

Storage

Drink immediately for the best texture. You can refrigerate it in a sealed jar for up to 24 hours; it will thicken and separate, so shake or re-blend before drinking. Do not leave a dairy smoothie at room temperature for more than 2 hours.
