Meatloaf is an American classic. It's quick and simple enough for a hearty dinner any night of the week. Cooking meatloaf in a pressure cooker cuts the time in half, and the result tastes the same as oven baked.
Combine all ingredients and shape into a loaf. Smother with ketchup.
Apply cooking spray to the bottom of the pressure cooker. Place meatloaf in the pressure cooker and brown for 2 minutes on high heat. Flip and repeat for the other side.
Add water. Close the pressure cooker, following the manufacturer's instructions. Set the cooker to 15 pounds pressure, or turn the stove to high heat until the gauge starts to vibrate. Then, turn it down to medium. The gauge should make a consistent noise. If it gets erratic, reduce the heat and/or briefly remove the pressure cooker from the stove. Cook for 15 minutes.
Remove the pressure cooker from the heat and wait about 15 minutes for it to cool. To be safe, run tap water over the lid and under the bottom of the cooker. If you do not hear hissing noises, nudge the gauge to make sure no steam is escaping. Open the pressure cooker according to the manufacturer's instructions, keeping your face away from the cooker. Use a potholder to remove the lid.
Remove the meatloaf and serve.
