A handy tip from what we've found is to let the parts cool down a little before washing, as this helps loosen any stuck-on bits, making them easier to remove. The splatter shield, which does a good job controlling smoke, is also removable and can go in the dishwasher, which is super convenient.

The manufacturer points out that these features aim to offer the benefits of outdoor grilling without the usual mess. They also suggest using a soft sponge and skipping abrasive pads to keep the non-stick surface in good shape.

Our research shows that people appreciate how this grill makes cleaning straightforward, fitting well with its user-friendly design. The idea of cleaning a multifunctional device might sound a bit overwhelming, especially after grilling, broiling, or air frying, but the easy-clean design ensures it doesn't become a chore.

Yep, you can definitely use olive oil with the Ninja FG551 Foodi Smart XL 6-in-1 Indoor Grill. This grill is super flexible, acting as a grill, air fryer, roaster, baker, broiler, and dehydrator.

Olive oil can add some nice flavor, especially when you're grilling or air frying. Just keep in mind that olive oil can smoke at high temperatures, so a light brush might be all you need.

The grill does a great job with a mix of meats and veggies, so if you're playing around with different flavors, olive oil could be a tasty option. Plus, the Smart Cook System, with its built-in thermometer, helps you nail the right doneness for meats.

Just remember, the grill cooks everything at the same temperature, so you'll need to time things well when cooking different types of foods together. It might take some trial and error, but according to our research, folks find it a great all-in-one solution for a small kitchen.

If you often need to cook foods at different temps simultaneously, you might want to look at options like a dual-basket air fryer, such as the Ninja Foodi 6-in-1 10-qt. XL 2-Basket Air Fryer, which gives you that flexibility.

So, go ahead and use olive oil with your Ninja FG551. It's a great choice for ramping up the flavors, whether you're grilling, air frying, or roasting. Just keep an eye on your cooking to get the best results from this multi-tasking gadget.

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!
