How to Make a Smoothie Thicker: 8 Fixes, From Less Liquid to the Order You Load the Blender

Most thin smoothies have too much liquid, not too little fruit. Cut the liquid to about half a cup per serving, use frozen fruit instead of fresh, and add one thickener such as Greek yogurt, rolled oats or chia seeds. Load the blender with liquid first and frozen ingredients last, and blend in short bursts. Those four changes fix almost every watery smoothie.

Here are eight fixes in detail, with USDA nutrition figures for the thickeners so you know what each one adds.

1. Start with less liquid

This is the fix that matters most. Many recipes call for a full cup or more of milk or juice per serving, which gives you something closer to a drink than a smoothie. Start with half a cup. You can always add a splash more if the blades stall, but you can't take liquid out.

Our starting point: roughly 1 part liquid to 2 parts solid ingredients by volume for a drinkable but thick smoothie. For a spoonable smoothie bowl, go lower still. Remember that yogurt and juicy fruit count partly as liquid, so if a recipe has both, trim the milk further.

2. Use frozen fruit, not fresh

Frozen fruit is the easiest thickener there is. It chills the smoothie, gives it a frosty texture and holds air as it blends. If you only have fresh fruit, freeze it in a single layer on a tray for a few hours, then bag it.

Two of the best frozen fruits for body, per USDA FoodData Central:

Mango, peaches and pineapple also freeze well and blend thick.

3. Add a creamy base

A spoonful of something creamy changes the texture more than extra fruit does.

| Thickener | Amount | Calories | Protein (g) | Fat (g) | Fiber (g) |
|---|---|---|---|---|---|
| Greek yogurt, plain nonfat | about 1/2 cup, 120 g | 71 | 12.2 | 0.5 | 0 |
| Soft or silken tofu | about 1/2 cup, 124 g | 76 | 8.9 | 4.6 | 0.2 |
| Avocado | 1/4 fruit, 50 g | 80 | 1.0 | 7.3 | 3.4 |
| Peanut butter, smooth | 2 tbsp, 32 g | 188 | 7.0 | 15.9 | 1.8 |
| Canned coconut milk | 2 tbsp, 30 g | 59 | 0.6 | 6.4 | n/a |

All values calculated from USDA FoodData Central (SR Legacy) per-100 g figures for the amounts shown.

Which creamy base to pick

The table points to different choices for different goals. For protein, Greek yogurt leads by a wide margin at about 12 g per half cup, with soft tofu next and a good dairy-free option. For a richer, dessert-style texture, avocado and coconut milk bring fat, which makes a smoothie feel thicker on the tongue; avocado also adds 3.4 g of fiber. Peanut butter is the most filling but also the most calorie-dense: two tablespoons carry about 188 calories, more than two and a half times the yogurt serving. Use one tablespoon if you mostly want flavor.

4. Use chia seeds or oats

Both soak up liquid and turn it into body.

If you're not used to fiber-rich smoothies, add these gradually. Our guide to smoothie fiber and bloating explains how to build up without discomfort.

5. Sneak in frozen vegetables

Frozen cauliflower and zucchini thicken a smoothie with almost no flavor. Half a cup of frozen cauliflower (66 g) has about 16 calories and 1.5 g of sugar, and half a cup of chopped zucchini (62 g) about 11 calories. Use them alongside a strongly flavored fruit such as berries or mango so the fruit carries the taste.

6. Load the blender in the right order

The order you add ingredients changes how evenly they blend. Vitamix's guidance for full-size containers is liquids first (it counts yogurt here), then softer ingredients such as tofu, then juicy fruits and vegetables, firmer produce, frozen fruit and finally ice. Its tips page explains why: heavier frozen items on top weigh the lighter ingredients down and prevent cavitation, the air pocket that forms around spinning blades. That air pocket is exactly what tempts people to pour in more milk.

For its 20-ounce personal cups and 8-ounce bowls, which are blended upside down, Vitamix reverses the order: ice and frozen ingredients go in first, so they end up next to the blades once the cup is flipped.

7. Blend less, and use the tamper

Over-blending warms the smoothie and thins it out as frozen fruit melts. Vitamix recommends starting on low and quickly ramping up to the highest speed, noting that blending on high shortens blend time. Stop as soon as it's smooth. For thick or frozen blends, Vitamix also says to use the tamper to move ingredients from the corners toward the blades, rather than adding liquid. If your blender has no tamper, switch it off, stir with a spatula, and blend again.

A weak blender is one of the most common reasons people add too much liquid. If yours struggles every morning, our roundup of blenders for smoothies compares options.

8. Rescue a smoothie that's already too thin

Already blended and it's watery? Try one of these:

Four habits that make smoothies thin

A thick everyday formula

Use this as a template for one serving:

  1. Liquid: 1/2 cup milk, plant milk or water.
  2. Creamy base: 1/2 cup Greek yogurt or soft tofu, or 1/4 avocado.
  3. Frozen fruit: 1 to 1 1/2 cups.
  4. Booster (optional): 1 tablespoon chia seeds or 1/4 cup oats.
  5. Flavor: a few mint leaves, cinnamon, vanilla, cocoa or citrus zest.

Load in that order, blend in short bursts, and adjust with a splash of liquid only if you need to.

Thick smoothies and sugar

A thick smoothie can be just as sugary as a thin one. Frozen fruit, dates and juice add up quickly. The UK's NHS counts the sugars in smoothies as free sugars and suggests no more than 150 ml of juice and smoothies combined a day. Building thickness from yogurt, tofu, avocado, oats, chia or frozen vegetables keeps the texture without leaning on extra fruit.
