From what we've found, the Ninja FG551 Foodi Smart XL 6-in-1 Indoor Grill is pretty solid when it comes to cooking steaks. It's got a bunch of features like air frying, baking, and broiling, but for grilling steaks, folks seem especially happy with it.
People really like how it can sear the steak nicely on the outside while keeping it juicy inside, thanks to the built-in smart thermometer and the high heat it can reach.
The manufacturer talks up its Smart Cook System—which is basically a thermometer that helps you get your steak cooked just the way you like it. So, whether you want your steak rare or well-done, it takes out the guesswork.
There is something to watch out for, though. To get the best results, the grill needs to be on a stable, level surface. We've seen mentions that if it tilts even a little, your steaks might not cook evenly since the unit could wobble or tip when you open the lid.
So, make sure your counter is nice and even or use a heat-resistant mat to sort it out.
All in all, if you set it up right, it sounds like the Ninja FG551 does a great job giving you those nice grill marks and a good crust. While there are the usual little quirks like stability to keep in mind, overall, it seems like a good pick for grilling steaks indoors.
Just stick to the setup tips in the manual, and you should be good to go with some tasty steaks!
