Nothing says “home” to me quite like the smell of Campbell’s Green Bean Casserole baking in the oven. This classic American dish has been the star of our family Thanksgiving table for as long as I can remember – my grandma always made it, my mom perfected it, and now I get to share my own little tricks with you. There’s something magical about how those crispy fried onions mingle with the creamy mushroom sauce and tender green beans.

After testing this recipe more times than I can count (sometimes with “help” from my kids sneaking extra onions), I’ve learned all the secrets to making Campbell’s Green Bean Casserole that’ll have everyone asking for seconds. It’s the ultimate comfort food that comes together with just five simple ingredients, yet tastes like you spent hours in the kitchen. Whether it’s your first time making it or you’re looking to improve your family’s favorite version, I’m excited to walk you through every step!

Ingredients for Campbell’s Green Bean Casserole

Here’s everything you’ll need to make this classic dish just right – I promise it’s all simple stuff you can find at any grocery store! The key is using Campbell’s Condensed Cream of Mushroom Soup (two 10.5 oz cans) – it’s the secret to that rich, creamy base we all love. You’ll also need:

  • 1 cup milk (whole milk makes it extra creamy, but any kind works)
  • 1/2 tsp black pepper (freshly cracked if you’ve got it!)
  • 4 cups cooked cut green beans (fresh, frozen, or canned all work – I’ll share my prep tips later)
  • 1 1/3 cups French’s Crispy Fried Onions (trust me, no substitutes here!)

That’s it! Five simple ingredients that transform into pure comfort food magic.

How to Make Campbell’s Green Bean Casserole

Okay, let’s get cooking! This recipe is so simple, but I’ve got some little tricks to make it extra special. First things first – preheat that oven to 350°F (175°C). I can’t tell you how many times I’ve forgotten this step and had to wait impatiently while my oven heats up!

  1. Mix the base: Grab a 1 1/2-quart baking dish (I use my trusty oval CorningWare) and stir together the Campbell’s soup, milk, and black pepper until smooth. No lumps allowed!
  2. Add the beans: Fold in your cooked green beans gently – you want them coated but not smashed. If using canned beans, drain them well first. Frozen? Thaw and pat dry.
  3. First onion layer: Sprinkle in 2/3 cup of those glorious French’s onions and mix just until distributed. The smell alone will make your mouth water!
  4. Bake: Pop it in the oven for 25 minutes. You’ll know it’s ready when the edges are bubbly and the center is hot – I always do the spoon test (careful, it’s hot!).
  5. The grand finale: Top with the remaining onions and bake 5 more minutes until they’re golden brown and crispy. Watch closely – they go from perfect to burnt fast!

Baking Tips for Perfect Campbell’s Green Bean Casserole

For the best results, bake on the middle oven rack – this gives even heat distribution. If your onions start browning too quickly, tent with foil. The casserole is done when it’s bubbling around the edges and a spoon comes out hot when dipped in the center. Want extra crispy onions? Add them in two batches – half at the beginning, then the rest in the last 5 minutes. And whatever you do, don’t stir after adding that final onion layer – we want those beauties crisp and proud on top!

Why You’ll Love This Campbell’s Green Bean Casserole

This isn’t just any green bean casserole – it’s the one that’ll have your family begging for the recipe! Here’s why it’s my go-to dish year after year:

  • Creamy dreamy texture – That perfect blend of Campbell’s soup and milk creates a velvety sauce that coats every green bean
  • Crunch you can’t resist – Those golden fried onions add the most satisfying crispy contrast to the creamy base
  • 5-minute prep magic – Seriously, it takes longer to preheat the oven than to mix everything together!
  • Universal crowd-pleaser – From picky kids to foodie grandparents, everyone comes back for seconds of this classic

It’s the kind of simple, comforting dish that makes holiday meals feel like home.

Ingredient Notes & Substitutions

Okay, let’s talk ingredients – because I know someone’s always wondering “Can I use…?” First, that Campbell’s Cream of Mushroom Soup is non-negotiable for me (it’s in the recipe name for a reason!). The generic brands just don’t have the same rich flavor. And heads up – low-sodium versions will make your casserole taste flat, so stick with the original.

For the green beans, here’s my cheat sheet: Fresh beans? Blanch them first (3 minutes in boiling water, then ice bath). Frozen? Thaw and pat dry to avoid extra moisture. Canned? Drain well – nobody wants a watery casserole!

Now about those onions – I’m team French’s all the way, but in a pinch, any crispy fried onions will do. Just don’t try making your own for this recipe – the texture won’t be the same. Trust me, I learned that the hard way!

Make-Ahead & Storage Instructions

Here’s my favorite thing about this casserole – you can prep it a whole day ahead! Just assemble everything (without the final onion topping), cover tightly, and refrigerate for up to 24 hours. When you’re ready, pop it in the oven (add 5-10 minutes to the bake time since it’s cold) and finish with those crispy onions.

Leftovers? They’ll keep in the fridge for 3-4 days. Reheat in a 350°F oven until warmed through (about 20 minutes) – microwaving makes the onions soggy. I don’t recommend freezing though – the creamy sauce separates and the onions lose their crunch. But let’s be honest – leftovers rarely last that long in my house anyway!

Serving Suggestions for Campbell’s Green Bean Casserole

This casserole is the ultimate team player at any meal! Of course it’s perfect with holiday turkey or glazed ham, but don’t wait for special occasions – it’s amazing with weeknight pot roast or grilled chicken too. For Thanksgiving, I love pairing it with mashed potatoes, cranberry sauce, and my grandma’s famous dinner rolls. The creamy, crunchy combo makes it the ideal side for rich meats – the tangy crispness cuts through all that savory goodness. Pro tip: Make extra fried onions for sprinkling at the table (my family fights over them!).

Common Questions About Campbell’s Green Bean Casserole

I’ve gotten so many great questions about this recipe over the years – here are the ones that come up most often!

Can I make this gluten-free? Absolutely!

Use gluten-free cream of mushroom soup (Pacific Foods makes a good one) and gluten-free fried onions. Just double-check all labels to be safe.

How do I double the recipe?

Easy – just use a 9×13 inch dish and double all ingredients. You might need an extra 5-10 minutes baking time. And yes, you’ll want to double those onions too – nobody ever complains about too many crispy bits!

Can I add fresh mushrooms?

Sure thing! Sauté 8oz sliced mushrooms in butter first, then mix them in with the green beans. It gives an extra earthy flavor that’s delicious.

Any vegan options?

Use plant-based cream of mushroom soup, almond milk, and vegan fried onions. The texture won’t be quite the same, but it’s still tasty!

How do I get perfect onion coverage?

My trick? Sprinkle half the onions in the mix, then press the rest lightly into the top before the final bake – they’ll stay crisp and cover every bite!
