Green Protein Smoothie

Green Protein Smoothie

Whole-Food • High-Protein • High-Fibre • Vegan • Vegetarian • Plant-Based • Dairy-Free • Gluten-Free Option • No Added Sugar

Introduction

This Green Protein Smoothie is a creamy, nourishing plant-based drink made with silken tofu, spinach, banana, peanut butter, ground flaxseed and unsweetened oat milk.

Instead of relying on protein powder, this smoothie gets much of its protein naturally from silken tofu and peanut butter, while spinach and flaxseed add extra nutrients and fibre. Banana provides natural sweetness and a creamy texture, meaning there's no need for added sugar.

The combination of protein, carbohydrates, fats and fibre makes this smoothie a more substantial option than a simple fruit smoothie. It's perfect for breakfast, after exercise or as a quick plant-based snack when you want something nutritious but easy to prepare.

Benefits of All the Ingredients

Unsweetened Oat Milk

Oat milk creates a smooth consistency and provides a mild flavour that works well with banana and peanut butter.

The nutritional profile varies considerably between brands. Fortified oat milks may provide nutrients including calcium, vitamin D and vitamin B12.

Choosing an unsweetened variety avoids unnecessary added sugar.

If preparing this smoothie for someone with coeliac disease, use oat milk made from certified gluten-free oats, as standard oats can be cross-contaminated with gluten-containing grains.

Silken Tofu

Silken tofu gives this smoothie its particularly creamy texture while providing a valuable source of plant-based protein.

Tofu is made from soybeans and provides complete plant protein containing all nine essential amino acids.

It can also provide iron, magnesium and other minerals. Calcium content varies depending on the coagulant used during production, so calcium-set tofu can provide considerably more calcium than some other varieties.

Its neutral flavour makes silken tofu especially useful in smoothies because it increases the protein content without overpowering the fruit.

Spinach

Spinach adds leafy greens while having a relatively mild flavour once blended with banana and peanut butter.

It provides vitamin K, folate, provitamin A carotenoids and vitamin C, alongside magnesium and fibre.

Spinach also naturally contains carotenoids including lutein and zeaxanthin.

Banana

Banana provides natural sweetness and helps create a thick, creamy smoothie without adding refined sugar.

It provides potassium, vitamin B6, vitamin C and dietary fibre.

Using a ripe banana produces a naturally sweeter smoothie, while a frozen banana can create an even thicker, colder texture.

Peanut Butter

Peanut butter adds richness, protein and a satisfying nutty flavour.

It provides plant-based protein and predominantly unsaturated fats, alongside magnesium, niacin and vitamin E.

For a whole-food-focused smoothie, choose natural peanut butter made primarily or entirely from peanuts without added sugar or hydrogenated oils.

Ground Flaxseed

Ground flaxseed adds fibre and healthy fats without significantly changing the flavour of the smoothie.

Flaxseed is particularly notable for providing alpha-linolenic acid (ALA), an essential plant-based omega-3 fatty acid.

It also provides dietary fibre, plant-based protein, magnesium and naturally occurring compounds called lignans.

Using ground rather than whole flaxseed makes its nutrients more accessible during digestion.

Together, the tofu, peanut butter, flaxseed, fruit and leafy greens make this Green Protein Smoothie a nourishing plant-based option with protein, fibre, healthy fats and a variety of micronutrients.
