Upgraded to one of these from the big black drawer type. Killer. We never fire the big oven up. This will do all kinds of things with the quartz rods in it top and below....
Chicken, smoked sausage, etc. etc.... I bought a dutch oven that will fit in it (7qt I think) from Amazon (their brand, great cast iron stuff and cheaper)... I put about four cans of the blue label navy beans, a couple onions, a pack of the smoked ham trimmings (dirt cheap) or thin sliced ham hocks (also dirt cheap), a couple of good size onions cut up, fresh ground black pepper, cover, and 2 hours @ 375º (air fry) and let er rip..... Killer and thick... Spoon will stand up in it.... Do NOT put salt. The canned beans have enough salt. I've done roast, potatoes, and onions in the same dutch oven too...
I'll also do sugar free pancake mix in muffin pan and they rise up like Yorkshire Pudding (ain't pudding)... Really pancake mix muffins.... I've done scrambled egg things in the muffin pan too...
Some things I use the silicone baking dishes and they work well and are easy to clean. Good bit less energy than big oven as the Ninja is basically a convection oven among other functions.... Air is constantly moving so stuff cooks faster as heat ain't just below rising up...
I love (well did until the plague and crap drove prices up) to get a pack of Kelley's smoked sausage, toss a few sections in the silicone dish, and then put wings on top...no batter, just spices and olive oil. Air fry and the smoked sausage below the wings add good flavor to the wings too. Wings will crisp up with no batter.... Haven't done it in a good while with same long flat of wings I used to get for ballpark seven bucks is now almost twenty bucks... Best investment I've made in a while I think... Love it...
Tip: Cast iron is the best in my book to cook stew, beans, etc., in.... Make sure it is seasoned. Before cooking in it, put a bit of olive oil in bottom, take a paper towel and coat all the inside with it. After cooking, to clean it, put water in it higher a touch than anything stuck to the sides. Bring to a good boil, stir water around to loosen everything. Turn eye off and let sit for several minutes. (You are gonna dump hot water in sink so you want it to cool a bit so you don't scald yourself by stupid human trick). Take a stiff dish brush and brush anything still stuck off and rinse several times with hot water. Wipe dry with paper towel, making sure everything is out of it. Then put a touch of olive oil in bottom, wipe entire inside down, then with another paper towel, wipe all excess oil out of inside. Done. No soap, brillo, etc.. I sit it back on stove where it is still pretty warm though off. That heats cast iron up a bit to make sure no water is still on it. Nonseasoned cast iron, when wet, you can almost watch it rust... Seasoned, used AND cleaned correctly, it ain't ever gonna rust and the seasoning will build up and it will become more and more nonstick as it ages... Think how fat in meat seasons cast iron grates in grill over time. Been a time when a rifle barrel, after changing from raw bright steel turned a brown patina, folks would take a tiny touch of bacon grease from breakfast cooked in pan over fire, on a rag corner, and wipe lock and barrel down. No more rust...
