  • Crock-Pot Green Bean Casserole

As soon as my kids were able to walk, they started following me around the kitchen and begging to help me cook. At first, I just let them assist with minor things like stirring pancake batter or cracking eggs. However, as they’ve gotten older, I’ve let them take on tasks that require a bit more precision, like measuring ingredients and using a dull-edged knife to chop certain ingredients. And if the recipe is super easy to follow, like this casserole, I’ll even let them make the whole dish themselves (with my supervision, of course). 

This green bean casserole is pretty foolproof, so it’s a great recipe to try if you’re a beginner in the kitchen or trying to teach your kiddos how to cook. Instead of a traditional casserole that’s baked in the oven, the ingredients simply get tossed into a crockpot and left to cook on low for a couple of hours. Despite its simplicity, it always comes out tasting amazing. It’s ultra-creamy, savory, and satisfying—and I love the contrasting textures between the soft green beans and the crispy fried onions. 

Cozy and comforting, it’s the perfect side dish to bring for potlucks and holiday gatherings. It only takes 10 minutes of prep, and then you can walk away and let the crockpot work its magic. Plus, cleanup couldn’t be easier, since it’s all made in one pot!

Make your own cream of mushroom soup

One of the biggest selling points of this dish is how easy it is to make. However, if you’re craving more of a homemade touch, you can certainly skip the canned cream of mushroom soup and make some from scratch. Begin by adding three tablespoons of oil or butter to a pan over medium-low heat. Add two cups of chopped fresh mushrooms, two cloves of minced garlic, and one-third cup of chopped shallots or onions. Sauté for several minutes until soft. Keep the heat low, and create a roux by stirring in one-quarter cup of flour. Slowly stir in one cup of milk until everything is well mixed. Add about 1 cup of vegetable broth, and simmer until thickened. This will make about two and a half cups of soup base, which is roughly the equivalent of two cans of cream of mushroom soup.

How do I store leftovers?

You’re in luck if you have leftovers, as this is one of those dishes that tastes great when reheated the next day. Allow your leftovers to cool completely, and then store them in an airtight container in the refrigerator for up to 4 days. To reheat, place the leftovers in a baking dish and warm in a 350°F oven for 15 to 20 minutes until they’re warmed through and the onions are crispy again. You can also freeze your leftovers for up to 3 months in an airtight container—just let it thaw overnight in the refrigerator before reheating.

Serving suggestions

For a hearty, satisfying meal, try serving this delicious green bean casserole alongside Braised Beef Short Ribs and Maple-Glazed Carrots. This dish is also a classic to serve at Thanksgiving dinner, so naturally it’d pair well with this Air-Fryer Turkey Breast, Garlic Mashed Potatoes, and Bread Stuffing.
