Ingredients

Gathering your ingredients is a breeze for this one. You’ll likely have most of them in your pantry already!

• 2 lbs fresh green beans, trimmed: This is the star! Make sure they’re washed and have those little stringy ends removed. Fresh makes all the difference here.
• 1 can (10.5 oz) cream of mushroom soup: The creamy, savory backbone of our casserole. No need for fancy brands; the classic works perfectly!
• 1/2 cup heavy cream: This adds an extra layer of richness and silkiness to the sauce. It makes it feel extra special.
• 1/2 cup grated Parmesan cheese: Hello, cheesy goodness! Parmesan brings a delightful salty, nutty flavor that complements the mushrooms beautifully.
• 1 cup fried onions: These are your crunchy topping! You can usually find them in the canned vegetable aisle. They’re the secret weapon for that irresistible texture.
• Salt and pepper, to taste: Just a little sprinkle to bring all the flavors together.

How to Make It

Alright, let’s get this magic started! You’ll be amazed at how simple it is.

1. Toss it all in: Grab your slow cooker. Trim your green beans if you haven’t already, then add them right into the pot. Pour in the can of cream of mushroom soup, the heavy cream, and the grated Parmesan cheese. Give it a gentle stir to make sure everything is coated nicely.
2. Season it up: Now’s the time to add your salt and pepper. I usually start with a good pinch of each and then taste it later to adjust if needed. Remember, the fried onions will add some saltiness too, so don’t go overboard at this stage!
3. Let the slow cooker work its magic: Put the lid on your slow cooker. You have two options here: cook on low for 4-6 hours or on high for 2-3 hours. The goal is for the green beans to be nice and tender. I usually opt for the low setting if I have time, as it tends to develop the flavors even more.
4. The grand finale: About 10-15 minutes before you’re ready to serve, open up that slow cooker. Stir in most of your fried onions – save a few for sprinkling on top for that extra crunch. Give it a final taste and add more salt and pepper if you think it needs it. Then, serve it up hot and watch it disappear!

Substitutions & Additions

While this recipe is fantastic as is, feel free to get creative! It’s your kitchen, after all!

• For a richer flavor: Swap out half of the cream of mushroom soup for cream of celery or cream of chicken soup for a slightly different but equally delicious profile.
• Add some umami: A tablespoon or two of Worcestershire sauce can add a fantastic depth of flavor.
• Cheesy variations: Feel free to mix in some shredded cheddar or Gruyere cheese along with the Parmesan for an extra cheesy kick.
• Fresh herbs: A sprinkle of fresh thyme or parsley stirred in at the end can add a lovely fresh note.
• Make it dairy-free/vegan: Use a dairy-free cream of mushroom soup alternative and a plant-based cream or milk. For the topping, you can find dairy-free crispy fried onions or make your own by breading and baking shallots.

Tips for Success

A few little tricks to ensure your Crockpot Green Bean Casserole is absolutely perfect every time.

• Don’t overcook the beans: While you want them tender, you don’t want them mushy. Keep an eye on them, especially if you’re using the high setting.
• The onions go in last: Adding the fried onions too early will make them soggy. Stirring them in right before serving keeps them perfectly crispy.
• Prep ahead: You can trim your green beans and mix the soup, cream, and cheese mixture the night before and store them in the fridge separately. Then, just dump them into the slow cooker in the morning!
• Adjusting consistency: If you find your casserole is a bit too thick, stir in a splash more heavy cream or a little milk. If it’s too thin, you can leave the lid ajar for the last 30 minutes of cooking to let some liquid evaporate.

How to Store It

Leftovers are the best, aren’t they? This casserole stores beautifully.

Once cooled, transfer any leftovers to an airtight container and store them in the refrigerator. It will stay fresh and delicious for about 3-4 days. To reheat, you can gently warm it up in the microwave or in a saucepan over low heat. If you like that crispy onion topping, I recommend adding fresh fried onions when you serve the leftovers!

FAQs

• Can I use frozen green beans? Yes, you can! Just make sure to thaw them completely and drain off any excess water before adding them to the slow cooker. You might need to adjust the cooking time slightly.
• Can I make this ahead of time and reheat it? Absolutely! You can assemble the entire casserole (minus the fried onions) and refrigerate it for up to 24 hours. Then, just add the fried onions before serving.
• What can I serve with this green bean casserole? It’s a fantastic side for almost any meal! It’s especially wonderful alongside roasted turkey, ham, roasted chicken, or even a hearty steak.
