Why Green Beans?

Green beans are a great option for catering weddings, family gatherings, parties, or business dinners! The nutritional value and simple preparation make them a perfect side to whatever you plan on serving as your main course. Whatever the occasion, you have picked the right side to serve with your meal!

Canned green beans are one of the simplest dishes to prepare. After removing the lid, they can be drained and warmed, or sauteed in a pan. There is no snapping or cutting the beans involved. This saves time and makes using canned green beans much easier to work with compared to other vegetables that require more preparation.

Green beans are also an adaptable dish. Whether you want to serve them plain or add a touch of bacon or mushrooms, you can create a dish that is personalized and delicious. Adding your own touch can turn something that is easy to prepare into a fancy dish that is sure to be a big hit.

As well as being adaptable, this side is healthy! Green beans are a great source of fiber, and they are both cholesterol-free and fat-free. They are high in vitamin K, which helps regulate blood calcium levels. They are fairly low in calories (with about 15 calories in one serving of drained beans) yet account for part of the required amount of vegetables a day. An adult should consume anywhere between 1 and 3 cups of vegetables a day, depending on their activity level.

Del Monte

Del Monte brand is one of the most popular brands of green beans and one of the most well-known brands, standing for quality, freshness, and reliability. Del Monte was the first major US food processor to add nutritional labeling to their products, helping make it easier for times like this when you are planning to feed a big crowd. This brand of green beans will not disappoint.

For Del Monte green beans, one serving size is 1/2 a cup of green beans. In a 14.5 oz can, there are approximately 3.5 servings. For one serving per person, this would require about 43 cans. At Walmart, this brand of green beans costs about $1.18 per can or $5.70 for a pack of 6 cans. 43 cans of Del Monte green beans would cost about $50.74 for individual cans and $45.60 for 8 packs of 6 cans.


Krasdale, established in 1908, is a leading food packing company and distributor which distributes food to New York City and other areas. Krasdale is a family-owned business and was one of the first businesses recruited to the Hunts Point Food Distribution Center. It is a company known for distributing vegetables and other foods.

The green beans they use are typically softer but are great for feeding large crowds and are easy to prepare. Just like Del Monte, a serving size is 1/2 c from a 14.5 oz can of green beans. A group of 150 people would also require about 43 cans of beans.

These beans can be purchased for $1.09, making them 9 cents cheaper than the Del Monte brand. For 43 cans of green beans, this would cost about $46.87. However, this brand of beans may be more difficult to find in local grocery stores. If this option is the one for you, you may have to check online or search stores near you. Shipping costs may make it a bit more expensive as well.

Green Giant

Green Giant is known for its US-grown vegetables. They do their best to harvest at the perfect time so that the vegetables on your table are as fresh as they can be. Green Giant knows the benefits of canned vegetables, including cost-effectiveness, convenience, and nutrition. They also know that canning vegetables can help reduce waste from uncanned vegetables.

Green Giant offers several styles of green beans, including cut green beans salted, unsalted, with 50% less sodium, french style, kitchen sliced, and green beans in a vegetable mix. They are the experts when it comes to feeding canned veggies to your family and friends.

Other Factors

When preparing to feed a group of 150 people or more, it is important to consider other factors, such as servings per person (maybe your party loves green beans!), how you are going to prepare the beans (drained or undrained), whether or not you want leftovers, and the size of the can you want to buy. There are usually larger can options if you want them, meaning you can pay for fewer individual cans in favor of a few larger ones.

According to Whitney Fredin Catering and Events, who serves out of Boise and Meridian, Idaho, at a typical catering event, they plan for one serving per person. However, if you are planning to serve seconds or want to be on the safe side, it may be better to plan for a few extra cans!

2 servings per person: 86 cans of green beans

The serving size of green beans may also change depending on whether or not the green beans are drained. When containing liquid, the serving size is 1/2 a cup. After the liquid is drained, one serving size of green beans is about 1/3 cup. While the amount of green beans ends up being about the same, it does alter the serving size slightly, according to the Food and Drug Administration.

One way to save money (and also time) is to buy your green beans in a larger-sized can. 28 oz cans of green beans can be purchased at Walmart, Amazon, or Albertsons, and contain approximately 7 servings. This would lower your total number of cans to 22. At Walmart, the cost of 28 oz of green beans costs $2.14.

Flavoring Ideas and Recipes

If you know you want to serve green beans at your event but are unsure of how to prepare them, let’s take a look at some different ideas for your green beans.

Depending on your guest list, it may make a difference in the way you season and flavor your beans. If many children are present, you might pick a flavor that most kids like, such as garlic butter or bacon. If you are serving a more mature group, beans and mushrooms may add a nice savory flavor to your plate.

Ideas for flavoring your green beans include salt, pepper, and butter, bacon bits, mushrooms, cheese, lemon glaze, garlic butter, and other seasonings.

It is important to note that depending on what you add to your green beans, the serving size may change. Adding sauce, cremes, bacon, other vegetables, or onions can decrease the serving size of green beans that you need to serve.

This means that you may need to purchase fewer cans of beans and purchase some other ingredients. Fewer cans of beans can leave room for other ingredients in your dish. Or, if you don’t purchase fewer cans, you might be preparing for when the guests at your event are coming back for more.

Let’s take a look at an easy recipe that you can make at your next event!
