This classic green bean side dish is a must for me and my family at any big feast. It's universally loved and it comes out so well with the slow cooker.
Add the cream of mushroom soup, milk, sour cream, seasonings and shredded cheese to the bottom of the crockpot. Use a wooden spoon or spatula to stir the ingredients until well combined.
21 ounces condensed cream of mushroom soup, ¾ cup milk, ¼ cup sour cream, ½ teaspoon garlic powder, ½ teaspoon kosher salt, ½ teaspoon ground black pepper, ½ cup freshly shredded Parmesan cheese
Dump in the green beans and half of the french fried onions, stir until just mixed.
58 ounces green beans, 6 ounces French fried onions
Cover and cook on low for 2-3 hours.
Stir well and pour the remaining french fried onions on top of the casserole. Serve warm, enjoy!

Notes
Cooked in a 6-quart Crockpot.
To store, place leftovers in an airtight container in the refrigerator for 3-5 days.
To prep ahead, follow steps 1 and 2 and cover. You can refrigerate overnight (or up to 3 days) and add an additional 30 minutes of cooking time to step 3 when ready to slow cook.
If you plan to keep the dish warm until ready to serve, wait to add the French fried onions until just before serving to avoid the onions becoming too soggy.
If substituting with frozen green beans, thaw first.
You can double the recipe if using a 6-quart or larger slow cooker. Cook for 2.5-3 hours.
For non-mushroom lovers, substitute with condensed cream of chicken soup.
Storage: Store crockpot green bean casserole in an airtight container in the refrigerator for up to 5 days or in the freezer for up to 3 months.
