Traditionally made with butter, canned soup, canned green beans and canned French-fried onions, green bean casserole–a classic Thanksgiving side dish since its invention more than 55 years ago—is high in calories, sodium and saturated fat. When you make your own healthier version from scratch using the following tips, you'll agree this is one culinary icon that was ready for a re-invention. We bet you will never go back to the from-the-can version again.

Here are our 5 secrets for making classic green bean casserole healthier, and arguably more delicious. And don't miss 4 Mistakes That Ruin Green Bean Casserole (and How to Fix Them).

1. Make Your Own Sauce

While condensed cream of mushroom soup is classic in a traditional green bean casserole, it is seriously high in sodium. Making your own mushroom cream sauce, using fresh mushrooms, lessens the sodium and bumps up the fresh flavor. Plus, if you have dietary restrictions you can control the ingredients to make your own gluten-free or dairy-free cream of mushroom.

2. Use Fresh or Frozen Green Beans

Take a healthier shortcut than canned green beans by using frozen green beans instead. Frozen green beans are a great quick-cooking item to have on hand, and are frozen at the peak of ripeness so they maintain their fresh flavor and vital nutrients. If you have a little more time, buy fresh green beans, they take a little bit longer to prep and cook but the fresh flavor and crisp texture is worth it!

3. Try Low-Fat Dairy or a Dairy Alternative

The traditional recipe for green bean casserole calls for butter, full-fat milk and sour cream, which, while adding richness, bump up the saturated fat and calorie count. If that's a concern, reach for ingredients like low-fat milk, reduced-fat sour cream and even unsweetened almond milk (which has less sugar and calories than dairy milk) for a vegan version. You can also use tangy buttermilk powder to add depth of flavor but not a lot of calories or fat (look for it in the baking section of your supermarket).

4. Add Flavor with Sherry

Sherry adds great depth of flavor to homemade green bean casserole. Be careful when shopping, though: don't use the high-sodium "cooking sherry" sold in many supermarkets and instead look for dry sherry, sold with other fortified wines.

5. Skip the Canned Onions

Cut calories and make your green bean casserole extra special by skipping the canned fried onions and sautéing your own. Tossing fresh onion slices with flour (or even gluten-free flour!) and pan-frying or oven-frying them in just a small amount of oil gives you the texture and flavor of the canned version without all the calories. Plus, they're so easy to make!
