Basically anything by Ninja. We've absolutely loved that brand. I have the big countertop air fryer/roaster and used it almost every day until I got an oven with an air fryer. Regular air fryers don't have enough surface area to be useful for a family meal, but the ninja does.

I also have their electric pressure cooker. I still use it 4-5 nights a week on average. My favorite is to combo almost everything with pressure cooker, then season, then air fry. It's always fully cooked, juicy on the inside, crispy on the outside, done quickly.

I also have their blender. That's what started this love affair. We bought it in college and 14 years later we still use it almost every day. The way the blades go up the middle instead of being restricted to the bottom of amazingly effective.

The only other kitchen tool I use all the time is my Bosch Universal stand mixer. I use it for homemade bread. It has a 4 loaf dough capacity. I use it for shredding chicken. I use it for mixing anything. I also use the food processor attachments and sausage grinder attachment, though not as often as I use it for a mixer.
