DIY: Slow-Cooker Probiotic Greek Yogurt

When it comes to choosing a healthy yogurt the supermarket can be a minefield. Most “healthy” yogurts (in fact, most “healthy” dairy products) are chock full of sugar. Especially bad are the ones with a low-fat stamp splashed across the packet. When fat is removed from a product, sugar is added to make up for loss of flavor.

So how to get around it? Make your own yogurt, of course!

Here's a super simple recipe to get you started!

Slow-Cooker Probiotic Greek Yogurt

Makes about 4 cups of yogurt


  • 8½ cups full-fat milk (preferably organic)
  • ½ cup full-fat organic, natural yogurt with live cultures, at room temperature

Special equipment

  • A slow cooker


Pour the milk into your slow cooker insert. Cover and cook on low for 2 1/2 hours. Allow mixture to sit for another 3 hours with the lid on.

Add yogurt to the milk and gently stir through, replace the lid. Wrap a bath towel around slow cooker and the lid. (Blocking out any light and keeping the cooker warm.) Leave the yogurt mixture in the slow cooker for 8-12 hours.

After 12 hours you will have slightly runny yogurt. Leave for a few hours longer if you want a thicker yogurt. For Greek-style yogurt, line a strainer with cheesecloth or with muslin. Place the strainer over a bowl (to catch excess whey) pour mixture into strainer and strain for at least one hour. The longer you strain, the thicker the yogurt will be.

Store in the fridge once desired consistency is achieved.

Tip: freeze the excess whey in ice cube trays and use for your next batch of yogurt. Simply remove from the freezer and allow to return to room temperature before adding to yogurt. Alternatively, add the whey to smoothies for a nice dose of probiotics.

Serving suggestions: sprinkle your yogurt with granola, cinnamon, brown rice syrup, cacao nibs or coconut flakes.
