Is the Instant Pot hard to learn for first-time users?

No, the core pressure cooking function requires three steps regardless of model: add ingredients and liquid, seal the lid (turn to lock position until the valve drops), and press Pressure Cook, set time, and press Start. The unit builds pressure over 10 to 15 minutes, cooks for the set time, then beeps. Release pressure via the quick release valve or wait for natural release. This sequence is the same across all Instant Pot models. The learning curve is primarily around pressure release timing (quick vs natural) and adjusting recipe cook times from conventional to pressure, which every standard pressure cooker recipe already specifies. Most beginners make one or two test batches before pressure cooking becomes intuitive.

What should I cook first in a new Instant Pot?

Hard-boiled eggs: the most forgiving and most demonstrative first use. Place 1 cup of water in the insert, add eggs on the trivet, seal the lid, and pressure cook on High for 5 minutes followed by 5-minute natural release. The eggs peel easily and are consistently cooked, demonstrating the pressure cooker's advantage over stovetop boiling. Second recipe: dried lentil soup. Dried lentils, diced vegetables, broth, and spices, seal and pressure cook on High for 15 minutes, natural release 10 minutes. No pre-soaking, done in under 30 minutes total, and the result is proof that pressure cooking genuinely saves time compared to the 45-minute stovetop alternative.
