Enjoying Healthy Green Bean Casserole All Year Long

Green bean casserole is traditionally a holiday-based dish. Most people enjoy this casserole on Christmas, Thanksgiving, and maybe Easter, but forget about it for the rest of the year. It doesn’t have to be this way! Don’t limit your green bean casserole to just the holiday seasons. Instead, add it throughout the year! In fact, while green beans are harvested all year long, green beans reach their peak season from early summer through mid-fall.

While we love to integrate seasonal produce into our diets, frozen green beans are still full of nutritional value, and cook very well from frozen. When out of season, we love grabbing a big bag Costco, and keeping them in our freezer for use in various dishes and casseroles.

Is Organic Necessary?

With green beans in particular, we highly recommend choosing organic. That’s because along with strawberries and peppers, green beans are one of the most heavily sprayed crops in conventional agriculture. It may be hard to stomach, but understanding exactly what is on your conventional green beans is incredibly important.

Worried about insects on organic produce? Organic growers have a variety of “clean” methods for keeping insect pests under control, and it really does make a difference in health and taste to go the extra organic mile when buying green beans.

Swap to organic green beans instead, and you’ll not only reap health benefits, but you’ll notice a ginormous increase in flavor! Trust us, it’s worth it.

How to Make Green Bean Casserole

As for green bean casserole, I realize there are two types of people; those who love green bean casserole, and those who don’t. Whether or not you love green bean casserole could be based upon your personal palate and liking towards green beans, or it could simply be based off of the recipes you’ve tried!

Even before clean eating, I was never a particularly big fan of mushroom soup on top of green beans. If you didn’t know, this method grew in popularity in the 50’s due to Campbell’s soup. However, I have always loved a good homemade green bean casserole.

One of the reasons people love the “cream of mushroom soup” method is because of the creaminess it adds. Thankfully, you absolutely do not need cream of mushrooms soup, or even dairy at all to achieve this same result!

We gave up dairy years ago to reduce our inflammation, and optimize our health. By now, we are basically professionals in delicious dairy-free alternatives! By opting for cashew cream, alongside fresh mushrooms, this recipe emulates the same texture and flavor, without all of the preservatives, sodium, and unhealthy ingredients. It really is as simple as that!

Tips for How to Make Green Bean Casserole Amazing

Follow the basic recipe for this casserole, and you’re going to have a deliciously tasty outcome. Follow some our tips for optimizing flavor, and making the BEST Green Bean Casserole, and your mind will be blown.

Here are our top tips for How to Make Green Bean Casserole Amazing…

Use Whole Green Beans

Whether frozen or fresh, something about whole green beans (AKA string or snap beans instead of thin ones like Hericot Verts) just adds a totally different flavor! After switching to whole green beans, I’ve never been able to go back!

Presoak Your Cashews

Presoaking your cashews is not a requirement to make yummy cashew cream. However, presoaking them for around 4 hours before using them will make for an even creamier, and smoother cashew cream. We promise, it’s worth it!

Sneak In a Superfood

The pumpkin seeds I use for the crumbly topping add just as much in nutrition as they do in taste.

Pumpkin seeds have lots of fiber, protein, omega fats and magnesium. They are also rich in the amino acid tryptophan—richer in fact than turkey (by the way, tryptophan increases the brain’s levels of mood-improving serotonin.)

When processed in a food processor and mixed with gluten free panko crumbs, the subtly sweet flavor and chewy texture of pumpkin seeds makes them perfect for a crumbly casserole topping. In fact, the crumbly topping is my favorite part of the whole dish. I promise you won’t miss the greasy French fried onions one bit.

If you don’t want to buy a pre-made version, you can make the crumbly topping by putting gluten free bread in a blender, and then toasting the crumbs at 400 for about 10 minutes.

As a side note, you might want to double the recipe for the crumbly topping and use it for baked fish, as a topping for salads or even on top of tomato soup.

Don’t Spend Too Much Time Cutting the Mushrooms

If they come pre-chopped…great! However, if not, be sure to resist the urge to chop the mushrooms into military uniformity—breaking them up by hand keeps them from assuming that canned texture, and makes them look truly homemade. A simple trick that leaves a big impression on your guests!

Use Clean Cookware

One part of a delicious, clean recipe that is often overused is using clean cookware! After all, the materials used in our cookware is often being transferred to our food, so it’s important you choose toxin-free! We absolutely love Xtrema’s 100% ceramic cookware, and especially love using their baking pan for casseroles, and recipes like this one!

Using fresh green beans? You can test the freshness of a green bean simply by bending it; if it is dull in color, rubbery and limp then you know it is past its prime. You want a lively bright green bean that bends a bit and then snaps right in half, that’s how you know it is fresh.
