Whether you’re a seasoned home cook or a curious beginner, this guide will help you unlock the secrets to making delicious yogurt right in your slow cooker.

Steps to Make Yogurt in a Slow Cooker

Making yogurt in a slow cooker involves a controlled process of heating, cooling, and incubating milk to allow the beneficial bacteria to ferment the lactose into lactic acid, which thickens the milk and develops the characteristic tangy flavor. The slow cooker provides a stable, warm environment ideal for this fermentation.

First, choose high-quality milk—whole milk produces creamier yogurt, but you can also use low-fat or skim milk depending on your preference. Pour the milk into the slow cooker and heat it to approximately 180°F (82°C). This step is essential to denature the proteins, which helps create a thicker final product and eliminates any competing bacteria.

After heating, remove the slow cooker insert and allow the milk to cool down to about 110°F (43°C). This temperature is optimal for the yogurt cultures to thrive without killing the beneficial bacteria. At this stage, you add the starter culture, which can be a few tablespoons of plain store-bought yogurt containing live active cultures or powdered yogurt starter.

Mix the starter thoroughly but gently into the cooled milk. Then, return the insert to the slow cooker base, and cover it with the lid. To maintain an ideal incubation temperature, you can wrap the slow cooker with a towel or blanket to retain heat, especially if your slow cooker does not have a “yogurt” setting.

The incubation period lasts between 6 to 12 hours, depending on the desired tartness and consistency. Longer incubation leads to tangier and thicker yogurt. Avoid disturbing the slow cooker during this time to ensure proper fermentation.

Once the yogurt has set, transfer the slow cooker insert to the refrigerator and chill the yogurt for several hours to stop fermentation and allow further thickening. Homemade yogurt can be stored in the refrigerator for up to two weeks.

Tips for Successful Slow Cooker Yogurt

Achieving consistent results when making yogurt in a slow cooker depends on attention to detail throughout the process. Here are key tips to enhance your yogurt-making experience:

  • Use fresh, high-quality milk and starter culture with live active bacteria.
  • Ensure accurate temperature control, especially during heating and incubation.
  • Avoid overheating the milk above 185°F to prevent a burnt taste.
  • Cool the milk properly before adding the starter to preserve bacterial viability.
  • Incubate in a warm, stable environment to promote fermentation.
  • Do not open the lid during incubation to maintain temperature.
  • For thicker yogurt, strain the finished product through cheesecloth to remove whey.
  • Experiment with incubation times to adjust tartness to your preference.

Using a Slow Cooker to Make Yogurt

Making yogurt in a slow cooker is a practical and effective method, leveraging the appliance’s ability to maintain consistent, low temperatures over several hours. This environment is ideal for the bacterial cultures in yogurt to ferment milk properly, resulting in creamy, tangy yogurt.

The process generally involves three key stages: heating the milk, cooling it to the optimal inoculation temperature, and incubating it to allow bacterial fermentation. Slow cookers can simplify the incubation phase due to their controlled heat settings.

Essential Equipment and Ingredients

  • Slow Cooker: Preferably with a low or “keep warm” setting that maintains temperatures between 100°F to 110°F (38°C to 43°C).
  • Milk: Whole milk is most common for creamy texture, but 2% or skim milk can also be used.
  • Yogurt Starter: Either a few tablespoons of plain yogurt with live active cultures or a commercial yogurt starter powder.
  • Thermometer: A kitchen thermometer is essential to monitor milk temperature accurately.
  • Optional Additions: Flavorings such as vanilla, sweeteners, or powdered milk to improve texture and taste.

Step-by-Step Process

Step Description Temperature & Time
Heat the Milk Pour milk into the slow cooker and heat it with the lid off until it reaches about 180°F (82°C). This step kills any unwanted bacteria and alters milk proteins for better yogurt texture. 180°F (82°C), approx. 1-2 hours
Cool the Milk Turn off the slow cooker and let the milk cool down to approximately 110°F (43°C), the ideal temperature to add the yogurt starter without killing the beneficial cultures. 110°F (43°C), cooling time varies (~30-60 minutes)
Add the Starter Mix a small amount of the cooled milk with the yogurt starter until smooth, then stir this mixture back into the slow cooker thoroughly. Maintain 110°F (43°C)
Incubate Cover with the lid and set the slow cooker to “keep warm” or the lowest setting to maintain temperature. Incubate for 6-12 hours depending on desired tartness and thickness. 100-110°F (38-43°C), 6-12 hours
Chill and Store Once incubation is complete, transfer the yogurt into containers, refrigerate for at least 4 hours to set completely, and enhance flavor. Refrigerator temperature, 4+ hours

Tips for Optimal Results

  • Temperature Control: Use a thermometer frequently to avoid overheating or underheating, as improper temperatures can inhibit bacterial growth or kill cultures.
  • Insulation: Wrap the slow cooker in a towel during incubation to help maintain consistent warmth, especially if your slow cooker does not have a “keep warm” setting.
  • Starter Quality: Use fresh yogurt with live active cultures for best fermentation results. Avoid flavored or sweetened yogurt as starters.
  • Milk Type: Higher fat content yields creamier yogurt, but adding powdered milk can improve texture regardless of milk fat percentage.
  • Flavoring: Add sweeteners or extracts only after fermentation to avoid interfering with bacterial activity.
