🥛 Why Lux Models Can Still Make Yogurt
If you own an Instant Pot Lux, you've probably noticed it doesn't have a "Yogurt" button. Most online tutorials simply say "press the Yogurt button" — which leaves Lux users stuck. But here's the good news: the Yogurt button is essentially just a low-temperature timer.
Its job is simple:
- Heat milk to 180°F–185°F for pasteurization
- Hold at about 110°F for several hours to ferment
The Lux model can do both of these manually using its Sauté function and passive insulation. All you need is a digital thermometer and a thick towel or blanket.

🌡️ The Science of Yogurt Making: Why Temperature Is Everything
Regardless of which Instant Pot model you own, yogurt success depends on hitting three critical temperature points:
| Stage | Target Temp | Purpose |
|---|---|---|
| Heat & Pasteurize | 180°F – 185°F | Kills unwanted bacteria and denatures milk proteins for thicker yogurt |
| Cool & Inoculate | 110°F – 115°F | Safe temperature for adding live cultures without killing them |
| Ferment | 100°F – 110°F | Warm environment where lactic acid bacteria multiply and thicken milk |

👩🍳 Step-by-Step Instructions
1 Heat the Milk to 180°F
Pour half a gallon of whole milk into your Instant Pot inner pot.
Select the Sauté function and set it to Low or Normal. Stir occasionally with a whisk to prevent the milk from scorching on the bottom.
Keep heating until the thermometer reads 180°F – 185°F. This usually takes about 30–40 minutes.
Once you hit the target temperature, press Cancel to stop heating.
2 Cool the Milk to 110°F
Remove the inner pot from the Instant Pot and let it cool on the counter. For faster cooling, place the pot in an ice water bath.
Your target is 110°F – 115°F. Monitor closely with your thermometer.
As it cools, a skin may form on the surface. Simply skim it off with a spoon.
3 Add the Starter Culture
When the milk reaches 110°F:
- Scoop about ½ cup of the warm milk into a small bowl
- Add 2 tablespoons of plain yogurt with live active cultures
- Whisk until completely smooth
- Pour the mixture back into the main pot and whisk thoroughly
4 Insulate and Ferment (8–12 Hours)
This is where the Lux model differs from models with a Yogurt button. Since you don't have an active warming mode, you'll rely on passive insulation:
- Place the inner pot back into the Instant Pot
- Cover with a lid (the regular Instant Pot lid or a glass lid)
- Turn the Instant Pot OFF — completely unplugged or powered down
- Wrap the entire Instant Pot in a thick towel or blanket
The towel traps heat, keeping the inside at the ideal fermentation range of 100°F – 110°F. The heavy stainless steel inner pot helps hold that warmth for hours.
Let it sit undisturbed for 8–12 hours. Do not open the lid or move the pot.
- 8 hours: Mild, slightly tangy, softer set — great for beginners
- 10 hours: Balanced tang and thicker texture
- 12 hours: Thick, tangy, and rich — closer to Greek yogurt
5 Chill and Set
After fermentation, open the lid. You should see a firm, pudding-like consistency.
Place the inner pot (covered) in the refrigerator and chill for at least 6 hours, preferably overnight. Chilling stops fermentation and thickens the yogurt further.
🥣 How to Make Greek Yogurt (Thicker & Higher Protein)
Want ultra-thick, protein-packed Greek yogurt? Just add one extra step:
- Line a fine-mesh strainer with 2–3 layers of cheesecloth
- Pour the chilled yogurt into the cheesecloth
- Set the strainer over a large bowl
- Refrigerate and let it drain for 2–4 hours
The longer it drains, the thicker it becomes. The yellowish liquid that drips out is whey — don't throw it away!
🔧 Troubleshooting Guide
| Problem | Possible Cause | Solution |
|---|---|---|
| Yogurt is runny / didn't set | Weak starter, temperature too low, or not enough time | Use fresh starter with live cultures; cool milk to 110°F before adding; ferment longer |
| Grainy or lumpy texture | Starter added when milk was too hot, or starter not mixed evenly | Cool milk below 110°F; whisk starter with a little warm milk before adding to the pot |
| Yellow liquid on top | Whey separation — completely normal | Stir it back in, or strain it out for thicker yogurt |
| Bitter or off flavor | Contaminated tools or too long fermentation | Sanitize all tools; reduce fermentation time; discard and start fresh |
| Still thin after fermentation | Not enough insulation; towel too thin | Wrap with extra towels or a blanket; place in a warm, draft-free spot |
❓ Frequently Asked Questions
Yes, but the yogurt will be thinner. For a creamier result, add 2–4 tablespoons of powdered milk or a splash of heavy cream.
Yes, but choose a plant yogurt with live cultures as your starter (or buy vegan yogurt cultures). Soy and coconut milk work best, though the texture will be thinner.
You can use your own yogurt as a starter for up to 3–5 batches. After that, the cultures weaken and you should "reset" with a fresh store-bought starter.
Stored in an airtight container in the refrigerator, it keeps for 1–2 weeks.
The Lux has no active "Yogurt" warming mode. Insulation is what holds the pot at fermentation temperature for 8+ hours. A thick towel or blanket is essential.
Yes — the same temperature principles apply. Heat milk to 180°F on high, cool to 110°F, wrap in towels, and let sit for 8–12 hours.
