There are a few things that every kitchen should have, that will make cooking easier. Not all appliances mentioned are necessary, as it will differ in the type of cooking/baking or other kitchen preparations you do. However, no matter which ones you elect to have, or not have - they are all helpful and serve a purpose in the kitchen.
Crockpot - This is a must for those that look to an appliance that does a lot of work with not a lot of effort. It is easy to drop all of the ingredients into a Crockpot, turn it on and leave for the day. Coming home to a sweet smelling meal has never been better. Crockpots are more typically used in the winter, but should definitely be considered in the summer. Not having to turn on the oven, means a much cooler kitchen while a family can still enjoy a hot home cooked meal.
Blender - A blender is useful for many things. Not only is it a good method for blending/mixing everything from drinks to cake batter, it can even chop veggies if the blender comes with that feature. It is important to look for a blender that has multi-functions to enable the chef to prepare more meals using this appliance. Multi-speeds are a must, interchangeable blades are a perk.
Oven/Stovetop - No kitchen would be complete without an oven and range. Most items are cooked using one of these two items, and cooking meals will be much more difficult without one. A stove top can hold up to four different items cooking at once, while an oven with multi-level racks can hold between two to four, depending on the size of the pan or dish inside.
Coffee Maker - This is an optional item that doesn’t necessarily fit within all kitchens. Drinking coffee is not a necessity to owning one, however a household that drinks coffee is more apt to have one. A coffee pot can boil water quickly, can create coffee OR tea, or can help brew coffee for a recipe. Many baked items call for coffee as an ingredient and having an inexpensive coffee maker will make this much easier to do.
Mixer - Mixer’s come in many styles. Some come with a bowl which makes mixing easier, but these can be pretty expensive. The perk of a bowl style mixer is that it can be turned on and left while other meal preparations are being made, all the while it is doing its job of mixing whatever is in the bowl. Having a hand mixer is equally as good, anything that makes mixing a bit quicker is better than trying to stir everything by hand.
Microwave - Microwaves are great. They can reheat leftovers, thaw frozen food and cook meals all by themselves. When it is time to purchase a microwave oven, it is important to look for a large capacity microwave, so that a single plate or larger can fit inside. This might be one of the most useful items in a kitchen.
Toaster Oven - A regular pop up toaster is great for a kitchen, but a toaster oven is a much better alternative. Smaller items can be cooked quickly inside a toaster oven and if a large meal is being prepared there is much less cooking time with this item.
There are about a dozen more appliances that would make kitchen duty a much easier job, but this is a good list to get started with. Especially if there is an interest in freezer cooking. These items all make a once a month cooking session a bit easier to get through.
