How It All Comes Together Step by Step
Step one, melt your butter or your olive oil-butter combo in the cooker on sauté mode. You gotta see that sizzle and smell the start of dinner.
Dump in your chopped onion and cook it till it gets soft and see-through, usually around 5 minutes. You spot the edges start to curl like it’s ready to go.
Add minced garlic next. Stir it for 1 or 2 minutes so it releases that garlicky punch without burning it.
Sprinkle in the flour now. Stir steady for a couple minutes to form that roux. This helps make the soup creamy and holds everything together.
Slowly pour in the broth while whisking. Scrape the bottom so nothing gets stuck or burnt. That’s where the flavor hides!
Drop in your cubed potatoes. Give a gentle mix and then put the lid on tight. Set your pressure cooker to high pressure for 10 minutes.
Once it’s done, hit quick release to stop the cook fast and keep potatoes just right. The sealing ring and steam cues keep everything perfect while that happens.
Open the lid, mash some potatoes for texture using a masher or immersion blender. Pour in milk and cream then gently stir to heat through. Add cheese, herbs, salt, pepper, and any cayenne or paprika if you're feeling bold. Stir till cheese melts and soup gets thick and creamy. You're ready to dig in!
Smart Shortcuts for Busy Days
- Use pre-minced garlic or garlic paste saved in fridge if you’re short on time but want flavor.
- Grab pre-chopped onions from your grocery’s produce section to skip that cutting step.
- Make the soup base ahead and freeze it; pressure cook later for a few mins just to heat up quick.
- Use shredded cheese bought fresh in bulk and freeze in portions so you always got some ready.
