Tips for making your green bean casserole the BEST…

Here is what we recommend for how early can you make Thanksgiving sides. You can also use our Thanksgiving non perishable foods list to help you with shelf stable cooking.

• Don’t use purple onions when making fried onions as they turn out a bit dark and unpleasant looking. Stick with white or yellow onions.
• Prepare the homemade fried onions up to three days in advance to save yourself time on Thanksgiving. Be sure to let them fully cool to room temperature before storing them in an airtight container or ziplock bag.
• Use Pacific brand cream of mushroom or chicken soup as it is gluten-free and not too thin in consistency.
• Be sure to season both the fried onions batter and the casserole itself with a bit of cracked black pepper. It adds a great depth of flavor!

Fresh or Canned Green Beans?

You may wonder why I use canned green beans instead of fresh. The truth is that I love a classic green bean casserole and the fresh just don’t give it that same flavor that grandma’s did.

What can I say, I am a very nostalgic person. If you like fresh green beans, most certainly feel free to use them.

No matter which you choose, one thing is certain. Everyone will love this dish! I dare you not to eat all those homemade fried onions before you get them into the casserole.
