First, melt 2 tablespoons of butter in a large skillet over medium heat. This is where the cooking journey starts.
Add in the minced garlic, sauté it for about a minute until you catch that amazing fragrance filling the kitchen.
Stir in the sliced mushrooms and cook them for 5 to 7 minutes. You want ‘em browned and tender but not mushy — get that perfect color.
Now add your green beans and the remaining 2 tablespoons of butter to the skillet. Give everything a good stir so the butter coats the veggies.
Transfer this mix into your pressure cooker. Seal it up tight with the sealing ring properly in place to avoid any leaks.
Set your pressure cooker to cook under high pressure for about 4 minutes. Wait for the pressure build and that satisfying valve hiss to let you know it’s working.
Once time's up, carefully use steam cues to do a quick release — watch out for that steam vent! You wanna keep the green beans still crisp, so don’t overdo it.
Open the cooker, season everything with kosher salt and freshly ground black pepper. Sprinkle with minced fresh parsley if you want a fresh twist before serving.
Notes
Serve fresh with a sprinkle of parsley for added flavor.
