Ninja 3-in-1 Cooking System - Model MC700/MC700C

© 2012 Euro-Pro/Ninja
An appliance that combines slow-cooking (like a crockpot), baking, browning, and roasting all in one machine sounds like a dream come true. Does it live up to the hype? Here is my review of the test results.


• Measurements: 18" length including handles, 13-1/2" width including knobs, 12" tall with lid on.

• Function dial switches between Stovetop, Slow Cook, and Oven allowing browning, sauteeing, slow cooking, steam cooking, and baking or roasting.

• Easy cleanup, non-stick interior surface. Apple juice completely evaporated and burnt to a crisp in the bottom lifted right out. Use non-stick plastic or silicone utensils.

• Includes a fine-mesh chrome roasting rack with handles, which is also surprisingly easy to clean, even with blackened, burnt bits.

• Use as a mini-oven during hot seasons to avoid heating up kitchen, much like a stand-alone roaster or crockpot.

• Can brown foods in the same base pot as roasting, baking, or slow-cooking, thus saving cleaning time.

• Browning meats and poultry will naturally reduce cooking time, so keep this in mind when converting your favorite recipes to this unit.

• Removable roasting pan is lightweight, unlike heavy slow-cooker crocks.

• Entire unit is lightweight, about 6 pounds.

• Unlike a sealed crockpot, the lid contains a small vent-hole. This is beneficial for roasting meats, as it helps avoid that "boiled" texture common with crockpots. (See Cons below.)

• Steam roasting is optimum for fish, seafood, vegetables, and puddings.

• When roasting, the temperature gauge toggles into a timer.

• Stovetop settings are Low, Medium, and High. Medium is suggested for sauteeing vegetables, while High is for browning. (See Cons below.)

• Lid handle stays cool to the touch. (See Cons below.)

• When steaming, plan on a cup of water lasting about 10 minutes before evaporating. You may need to replenish water often with some recipes. Water must not come higher than the bottom of the roasting rack.

• Base roasting pan is dishwasher safe, however, the roasting rack and lid are not. They are so easy to clean, I don't even bother with the dishwasher.

• The unit may be used as a buffet server to keep foods warm for 30 minutes up to 12 hours.

• 8-inch square glass baking dishes will fit the cooking pan and rack. Small, toaster-oven size foil baking pans will fit. Most 9-inch loaf pans are fine. There is a listing of miniature baking accessories with sizes that will fit.

• A small cookbook with 25 recipes is included. The Ninja website package includes a larger recipe book with 150+ recipes, although the price is higher than retail outlets. There is also a limited collection of recipes on the website.

• Some recipes are also included for making an entire meal in the unit, such as a main dish, side dish, and vegetable.

• Ninja Helpline for questions: 1 (877) 646-5288.


• Exterior of the unit gets very hot when in use. Be careful not to bump into it.

• There is no buzzer, beeper, chime, or any other auditory sound when the timer runs out. In the bake mode, the heat will turn off after about 60 seconds. In slow-cook mode, it will automatically switch to a warm setting.

• As with crockpot recipes, in order to get any color on the food, it must be browned first.

• Placing the roasting rack into the hot base, and removing it, is awkward due to the handle design on the rack. You will need silicone oven mitts to avoid getting burned.

• Although the manual says no pre-heating is required, I found the stovetop High setting took a very long time to get hot. I resorted to using the oven setting at 425 F. for browning. Even so, it will not get as hot as a skillet, so browning will take longer than the traditional skillet method.

• Foods will get quite browned and crunchy when cooked directly in the base pan without the roasting rack. This is due to the roasting pan resting directly on the heating unit. This can be detrimental to some roasts, so I suggest using the roasting rack inside the pan for meats. However, it is a positive feature for those who like browned, crunchy-edged vegetables or macaroni and cheese.

• When slow-cooking and steam-roasting, you may need to add water because the vent-hole allows moisture to escape. This can be a nagging babysitting ordeal with some recipes.

• The unit must be used on an open counter due to the vent-hole. Do not use it pushed back under overhead cabinets and be sure the vent-hole in the lid is facing outward.

• Baked desserts must be inverted to show any color or choose recipes that will be frosted with icing or topped in some manner to cover pale tops.

• When using for baking cupcakes, individual silicone baking cups must be used in order to fit the rack. Maximum of 6 cupcakes at a time, which could mean multiple batches for most standard recipes.

• Largest baking pan to fit roasting rack is 9" x 8"; without the rack the size is 10" x 8".

• Maximum width is 8" so a pie pan will not fit.

• When trying some of the recipes in the cookbooks, I found that many needed cooking time adjustments, both up and down.

The Bottom Line

You have to admit, being able to bake, roast, steam, and slow-cook all using the same unit is a pretty cool concept. It does live up to its claims for the most part, albeit perhaps not in the exact way to which you are accustomed.

I like this appliance best as a roaster. If the price were less, I'd recommend it for that purpose alone. It works great for roasting chickens, beef, pork, and lamb without heating up the kitchen and uses much less energy. Most of all, clean-up is a dream. Don't even waste room in your dishwasher.

I doubt I'll use the stove-top mode much. It just doesn't get hot enough to replace a skillet without adding cooking time. I probably won't use it to steam-bake either, although it functions fine. It's nice to have the option. Although I tried some recipes for baked goods, it just can't compete with a traditional oven for that purpose. Space is limited, necessitating smaller batches and equipment.

The one-pot meal options, using a layering effect with the rack, were just okay. Due to the nature of the design, whatever is on the bare bottom (under the rack) is going to get brown and crusty. This can be fine for some foods, like potatoes and casseroles, but doesn't work as well for pasta dishes with the protein layered on the rack.

I'm on the fence about the unit replacing my crockpot slow cooker. It boils down, so to speak, to the vent-hole which allows moisture to escape. It does the job as a slow cooker, but may need a watchful eye to be sure you don't lose too much moisture with some traditional crockpot recipes. This rather defeats the purpose of setting and forgetting, to borrow a phrase. On the other hand, if you like your roasts well done, use the rack and let it go. When using the rack, you won't have to worry about the bottom getting too crusty, and you won't get that boiled texture as with a crockpot. Be forewarned that you may notice a burning smell as the juices drip to the bottom, evaporate, and burn. Good thing clean-up is a snap.

Overall, the unit performs as advertised, with the caveats listed above. I'm using it a lot as a roaster, but I won't be giving up my skillets or crockpot anytime soon. The other options are nice, but may not work as well as you expect. Your mileage may vary.

Sailor takes to remote Island, Member navy4you2

I am in the Navy and have been stationed on a very remote island. I brought the Ninja as the only source for cooking. (since it is just a small room) I have used it for many things. I love being able to make the spaghetti and frozen meatballs (made the meatballs myself and froze them), I have baked a loaf of bread in it, cooked chicken and a steamed potato, meatloaf, bbq pulled pork with 1/2 of a 19# pork butt, sauteed onions and I have even made dumplings in it. I think this is the most versatile system that I could have gotten and for the money it is price perfectly. (Watch for sales too.) I hope that if you get this and try it out, don't try to steam things all day, and make sure if you are using anything other than the crock pot part that you watch it just like you would being at home with the oven or stove top. I said it a couple of times and I will say it again.... I love this thing. I can't say enough about it.
