10 Ways To Keep Appetizers Warm

Serving cold food that SHOULD be warm is my ultimate fear when hosting a party. Unfortunately, keeping food warm for hours is NOT easy, especially when you have a crowd of people who are arriving at different times and eating throughout the party OR if you want to transfer food to another location.

You have temperature safe zones to consider plus the fact that food easily dries out over time the longer it's heated.

Since food, in my opinion, is the MOST important thing at a party, I wanted to share some valuable advice with you that I have learned so you don't make the same mistakes I've made!

Catering your party? Here is a list of appetizers perfect for catering!

Below I am sharing techniques caterers use to reheat foods and keep foods warm with and without electricity. Most are pretty simple and can be replicated at your next party whether it's indoor or outdoor!

Keep in mind, many of these tips may require purchasing items or equipment so think about what makes the most sense to purchase, what is the best investment for your future parties and most importantly, what works within your budget!

If you have company over more than once a year, investing in a good set of durable food warmers is one of the BEST investments you will make! They are worth every penny. Plus, they look nice and can allow you to set the food out way before the party starts! Stress-free entertaining? I'm all in!

1. Chafing Dishes

There's a reason this is the most popular type of food warmer! Chafing dishes are simply portable catering pans that sit over top of a frame or tripod. Water is poured underneath and then the water is heated using small flames like sternos. Check out my top chafing dish picks!

They are an investment and should be your number one choice for keeping food warm if you have electricity and room for them!

You can purchase inexpensive aluminum ones that will do the trick or invest in fancier ones that will last a lifetime. Either way, if you're hosting a party that where the food is served buffet style, this is the best option!

2. Electric Food Warmers

➡️This electric warmer (shown below) is my FAVORITE! Everyone that comes over my house tells me how much they love these and end up buying one.

Electric food warmers are awesome. They do not require any water or flames and are much easier to set up. The one con is that they require electricity to run. So you have to take the cost into consideration as well as the location where you want to set them up.

IMPORTANT! I did not realize when I purchased these food warmers how short the cords are. So make sure to grab some three prong extension cords!

Stainless Steel Warming Tray & Buffet Server

Because of the small trays, this one is perfect for warming sides or appetizers. The lids are clear so you can see through them plus they have a stand to place the lids on while serving yourself.

My favorite thing is the warming tray itself. You can remove the buffet trays and expose one single warming tray that is flat. This is great for placing casserole dishes on or foods you want to slightly warm while crisping the bottom like breads or finger foods.

Electric Slow Cooker With Triple Mini Crock Pots

These mini crock pots are awesome for serving dips or sides. They are ideal for a taco bar or any food bar where you want to heat multiple sides or toppings at once. IT really is such a fun warming station that does not take up much space.

3. Thermal Cookers

Thermos' are not just for your kid's lunch! They are great for keeping food warm for HOURS without needing any electricity or flame making them perfect for soups, stews or sauces. Best of all, they pour easily so they're ready to serve!

Thermal cookers are amazing. To use one, you do NOT need any electricity. It uses the insulated heat and keeps your food hot for many hours. Read more about how they work here.

This thermal cooker is one of the best out there. Stainless Steel Vacuum Insulated Thermal Cooker.

4. Coolers

Yes! Coolers can be used to keep foods HOT too!

You probably think of ice when the word cooler comes into mind but what we may forget is that coolers are great for insulating anything whether its cold OR hot.

What the pro's use:

You can turn your cooler into a HOT BOX or a 'Cambro'. Caterering companies use a Cambro all the time for weddings or large events.

How To Use A Cooler to Keep Food Warm For Hours:

You can keep food safely warm in a cooler for 4-6 hours if you take the proper steps to turn your cooler into a 'hot box'.

What you want to do is heat water up in a large pot on the stove. Then add the water to an empty cooler and let it sit for at least 5 minutes. This will bring the cooler's internal temperature up so when you place the food in, the cooler will not "steal" heat from the food. Then, when your ready to start insulating, pour out the hot water.

To properly insulate, line the cooler with heavy duty aluminum foil followed by a few towels. This will add extra insulation to the cooler. Then wrap your containers or dishes fully with more aluminum foil and a towel and place neatly inside the cooler with extra towels snuggled around the food so it does not shift or allow air flow.

*Keeping the lid closed until ready to serve the food will keep the heat in longer!

This cooler is one of the top rated coolers out here.

Three ways to add even MORE heat to your cooler next to your towels:

• Water Bottles: An extra way to maintain the heat in a cooler is to use water bottles. Just add very hot water to any water bottle you have in your house and close it up. Lay them around the sides, bottom and top of the cooler.
• Rice or Beans: Add some rice or beans to some large socks and tie them in a knot. Place them in the microwave for a few minutes or until hot. Place under and around your food. Rice and beans hold heat very well and are a cheap alternative to adding heat to your cooler.
• Hot bricks: Go to your local Home Depot or Lowes and purchase 4-6 unglazed bricks for super cheap. Then, wrap them in sturdy aluminum foil and heat the bricks in the oven at 400ºF for 30-40 minutes. Carefully remove them and place them on top of some moist towels on the bottom of your cooler. The moisture helps to maintain heat while the bricks help to retain heat.

Be careful stacking your food in a cooler! If you want to warm multiple dishes, you'll need to stack your food. To do this, use an empty cardboard box and cut a piece of cardboard as wide as the cooler.

This will be a make-shift 'shelf' to place the food on. OR, you can purchase these oven-safe casserole dishes which have sturdy lids allowing you to stack them easily without a mess!

5. Use Thermal Insulated Bags

Using coolers is a GREAT way to keep food warm for hours! These are great for both at home and traveling! They are easier to carry then large coolers and do a great job insulating food! You can use the same strategies I mentioned above to help lock in as much heat as possible.

Wrap your lasagna, vegetables meat, etc. in a few casserole dishes and wrap in tin foil. Stack them on top of each other and place them inside a bag. Your entire dinner will be nice and hot for when you (or your guests) arrive at the party!

6. Heat Lamps

Heat lamps are used in every single restaurant for good reason! Once the food is ready, chefs will place it under a heat lamp until the server comes to take it away. It does a great job at keeping food warm especially food that is meant to stay crispy! It is really great for appetizers!

7. A Slow Cooker/Crock Pot

Most of us have slow cookers (or crock pots) already however we don't think about using them to keep food warm for parties.

You can use your slow cooker to keep for warm as long as the temperature of the food stays above 140 degrees F. Here are some tips for using it for a party:

• Add WARMED food to your slow cooker. This way, the slow cooker wont need to spend time or energy heating itself AND the food. Warm the food up BEFORE adding it to your slow cooker if it was made prior to the party.
• If your food is already cooked, make sure to set your slow cooker to the 'WARM' setting so the food does not over-cook.
• Have a place to put the lid! It is hard to juggle a plate, spoon and a lid at once. Plus, we all know how much condensation forms on the inside of those lids so if guests are helping themselves, have a clean dish towel nearby for them to lay it on.
• Triple mini crock pots are so great for warming sides, dips or sauces! These here are beautiful!

8. Use A Thermal Cooker

A thermal cooker, also known as a thermal pot or a vacuum pot, is a fantastic appliance for keeping food warm for an extended period without using electricity. Here's how to use a thermal cooker to keep food warm:

1. Prepare the Food: Begin by cooking your food as you normally would, ensuring that it's thoroughly heated or cooked to your desired temperature.
2. Preheat the Thermal Cooker: Fill the inner pot of the thermal cooker with boiling water. This step is crucial to preheat the pot and ensure it's hot before adding your food. Allow the hot water to sit in the pot for a few minutes, then pour it out.
3. Transfer the Hot Food: Place the hot or freshly cooked food into the inner pot of the thermal cooker. Ensure that the food fills the pot as much as possible to minimize heat loss.
4. Seal the Pot: Close the lid of the inner pot securely to create an airtight seal. Some thermal cookers may have a locking mechanism to ensure a tight seal.
5. Insert the Inner Pot into the Outer Pot: The thermal cooker consists of an inner pot and an outer pot. Insert the sealed inner pot into the outer pot. The outer pot is designed to have excellent insulation, which will help retain the heat.
6. Leave it Undisturbed: Once the inner pot is placed inside the outer pot, do not open the thermal cooker for the duration you want to keep the food warm. Opening the cooker will release the heat, reducing its effectiveness.
7. Wait for the Food to Stay Warm: The insulation of the thermal cooker will keep the food hot for several hours, often up to 4-8 hours or more, depending on the model and the initial food temperature. This makes it an excellent tool for keeping food warm while you prepare other dishes, travel, or serve meals later.
8. Serve when Ready: When you're ready to serve, open the thermal cooker, remove the inner pot, and dish out the hot food. Remember that the food will be at or near the temperature it was when placed inside the cooker.

9. Aluminum Tins

Aluminum tins or foil containers are CHEAP and can be quite effective at keeping food warm, especially when used correctly. Here are some steps to help you use aluminum tins to keep your food warm:

1. Choose the Right Container:

   • Select an aluminum tin or foil container that is appropriate for the quantity and type of food you want to keep warm. Make sure it has a tight-fitting lid to seal in heat.

2. Prepare the Food:

   • Cook or heat your food to the desired temperature before placing it in the aluminum tin. Hot food will stay warm longer than food that's lukewarm.

3. Use Foil or Plastic Wrap:

   • To ensure a tight seal and prevent heat from escaping, cover the top of the aluminum tin with a layer of aluminum foil or plastic wrap before placing the lid on.

4. Fill the Container:

   • Carefully transfer your hot food into the aluminum tin. Leave some space at the top to avoid spillage and to allow for the expansion of steam.

5. Seal the Lid:

   • Securely close the aluminum tin with its lid. Ensure there are no gaps or openings that could allow heat to escape.

6. Wrap in Towels or Blankets:

   • To enhance insulation, you can wrap the aluminum tin in clean towels or blankets. This will help trap heat and keep the food warm for a longer period, especially during transportation.

10. Your Home Appliances

Take advantage of what you already have in your home.

The Oven!

This is one of the most POPULAR ways people like to keep food warm! It's free and does not require too much added effort! The 'warm' setting is about 200ºF. If you don't have a 'warm' setting, just set your oven's temperature to this setting and wrap food in tin foil before you place it in your oven. Don't set the temperature too high, or leave your food in too long or it will dry out! Aluminum foil will prevent the food from drying out too much so make sure to use some.

Tip* The warm setting temperature for your oven in Celsius is about 93ºC.

Your Toaster Oven!

Toaster ovens are great because they heat up much quicker than a regular sized oven! If your using one, set the temperature to the lowest 'BAKE' setting. This way your food wont burn or dry out. Toaster ovens are perfect for keeping items warm like bread, small appetizers or even dips!

Plan In Advance What Time Food Will Be Served

Time and food can be enemies especially when warming foods for long periods of time. You don't want your food to dry out. You also want to make sure your food never drops into the "danger zone" which is between 40ºF and 140ºF. Once it does, you have TWO hours before bacteria will start to grow.

With that said, it is important to determine how long your food will be left out without heat.

Two hours is not a long time so if you're serving a sit-down dinner, you want to keep the food over 140ºF until last minute and serve the food directly from the oven straight to the table.

If you're serving food buffet style, it is easiest to have food out the entire party so everyone can continue to help themselves throughout the day or night. If that's the case, you will need to make sure your food has time to heat up before guests help themselves and will stay heated until the end of the party.

Some chafing dishes can take over an hour to heat the food all the way through so make sure you take this time into consideration!

TIP* Starting with HOT water underneath your dish and using larger sternos are both smart tricks to get your food warmers ready faster!

And always, ALWAYS have backup sternos ready to go when one goes out!

Invest In A Quick Read Thermometer

If you are keeping food warm for longer than 2-3 hours, I highly recommend using a quick read thermometer to help you stay on top of the temperature of the food.

This way if you see something dropping too close to the danger zone, you can throw it in the oven or add another sterno to bring the temperature back up to the safe zone.
