What Is Campbell’s Green Bean Casserole?
This iconic dish was created in 1955 by Dorcas Reilly, a home economist working in Campbell’s test kitchen. The goal was simple: create an easy, delicious side dish using two pantry staples — Campbell’s Cream of Mushroom Soup and canned green beans.
It worked. Spectacularly.
Today, it’s estimated that over 20 million Campbell’s Green Bean Casseroles are made each year, particularly around Thanksgiving and Christmas. Its appeal is timeless: it’s creamy, savory, topped with those irresistible crispy fried onions, and — perhaps most importantly — it comes together in minutes.
It’s the original easy green bean casserole, and it’s been earning a spot at the holiday table ever since.
Ingredients for the Classic Recipe
This is what you’ll need for a standard 6-serving classic holiday casserole:
1 can (10.5 oz) Campbell’s Cream of Mushroom Soup
¾ cup whole milk
1 tsp soy sauce
¼ tsp black pepper
4 cups cooked cut green beans (fresh, frozen, or 2 cans)
1⅓ cups French’s Crispy Fried Onions, divided
Salt to taste
Optional: garlic powder (½ tsp)
Optional Healthier Substitutions
- Use Campbell’s Healthy Request Cream of Mushroom for lower sodium.
- Swap whole milk for unsweetened almond milk to reduce carbs.
- Use fresh green beans (blanched) instead of canned for better texture and nutrients.
- Replace fried onions with crushed pork rinds for a keto-friendly crunch.
Step-by-Step Instructions
This creamy green bean casserole recipe couldn’t be simpler. Here’s exactly how to make it:
1
Preheat Your Oven Set your oven to 350°F (175°C). Lightly grease a 1.5-quart baking dish.
2
Make the Creamy Base In a large bowl, stir together the Campbell’s Cream of Mushroom Soup, milk, soy sauce, and black pepper until smooth and well combined.
3
Add Green Beans & Onions Stir in the green beans and ⅔ cup of the crispy fried onions. Mix until everything is evenly coated in the creamy sauce.
4
Transfer & Bake Pour the mixture into your prepared baking dish and spread evenly. Bake uncovered for 25 minutes, until the casserole is hot and bubbly around the edges.
5
Add the Topping & Finish Remove from the oven and sprinkle the remaining ⅔ cup of crispy fried onions over the top. Return to the oven for another 5 minutes, until the onions are golden brown and perfectly crispy.
6
Rest & Serve Let the casserole rest for 5 minutes before serving. This allows the sauce to settle and thicken slightly. Enjoy!
Keto-Friendly Green Bean Casserole Variation
Love this dish but following a low-carb lifestyle? Good news: this classic holiday casserole is surprisingly easy to keto-fy with a few smart swaps.
🥦 Keto Swaps That Work
Replace canned soup with homemade mushroom cream sauce (heavy cream + sautéed mushrooms + garlic)
Use unsweetened almond milk or heavy cream instead of whole milk
Swap fried onions for crushed pork rinds mixed with parmesan — same crunch, zero carbs
Use fresh or frozen green beans (skip canned to avoid added sodium and starch)
Add crumbled bacon on top for extra fat and flavor
These tweaks make a delicious, satisfying keto-friendly version of the original — but if you’re serious about making keto work long-term, one modified recipe won’t cut it. You need a complete system.

Tips for the Best Green Bean Casserole
Cooking Tips
- Don’t overbake. The key to a creamy green bean casserole — not a dry one — is pulling it from the oven the moment it starts bubbling at the edges.
- Always add onions in two stages. Mixing some into the filling and topping with the rest ensures you get crispy onions throughout and on top.
- Use fresh green beans when possible. Blanch them for 5 minutes in salted boiling water, then shock in ice water. They hold their color and texture far better than canned.
- Season at every stage. Taste the sauce before baking and adjust salt, pepper, or garlic powder as needed.
Storage & Reheating
- Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
- Reheat in the oven at 350°F for 15–20 minutes. Avoid the microwave if you want to preserve the crispy topping — add fresh fried onions before reheating.
- This dish does not freeze particularly well once baked, but you can freeze the unbaked filling (without the onion topping) for up to 1 month. Add topping and bake directly from frozen, adding 15–20 extra minutes.
Why Meal Planning Matters More Than Any Single Recipe
Here’s a truth most food blogs won’t tell you: knowing one great recipe won’t change your health. What changes your health is consistency — and consistency comes from having a plan.
Without a plan, most of us fall into the same trap. We start the week with good intentions. By Wednesday, we’re exhausted, staring at an empty fridge, and ordering takeout. Again. The cycle repeats. Progress stalls. Frustration builds.
That’s not a willpower problem. That’s a planning problem — and it has a very straightforward solution.
The Done-For-You Difference
The 30-Day Keto Meal Plan for Busy Beginners eliminates the guesswork entirely. Here’s what’s included:
- A full 30 days of breakfast, lunch, dinner, and snack ideas — no repeating, no boredom
- Ready-to-use grocery lists organized by week so shopping takes minutes, not an hour
- Recipes designed for busy people — quick prep times, simple ingredients, real results
- A clear structure that removes decision fatigue and helps you stay consistent even on your hardest days
When you have a done-for-you system, you stop white-knuckling your diet and start actually enjoying what you eat. That’s the real secret to long-term success.

Frequently Asked Questions
Can I make it ahead?
Absolutely — and it’s a great idea for holidays. Prepare the full casserole (without the onion topping) up to 24 hours in advance, cover it tightly, and refrigerate. When ready to bake, add the onion topping and bake as directed, adding 5–10 extra minutes since it’s starting cold.
Can I freeze it?
Freeze the unbaked filling (without onion topping) for up to 1 month in a freezer-safe dish. When ready to use, thaw in the refrigerator overnight, top with onions, and bake as directed. Baked leftovers don’t freeze as well — the sauce can separate and the texture suffers.
How do I make it healthier?
Start with the substitutions in our ingredients section — fresh green beans, low-sodium soup, and almond milk are easy wins. For a full keto version, try our variation above. And if you’re committed to eating healthier consistently — not just for one recipe — the 30-Day Keto Meal Plan for Busy Beginners gives you a complete, structured approach to eating well without the stress of figuring it out yourself.
Why does my casserole turn out watery?
This usually happens when using canned green beans without draining them thoroughly, or when the casserole is slightly underbaked. Drain and pat dry your green beans before mixing, and make sure your casserole is genuinely hot and bubbly before adding the final onion topping.
Can I add other vegetables?
Yes! Sliced mushrooms, diced red bell pepper, or blanched broccoli florets all work wonderfully. They add color, nutrition, and texture without disrupting the classic creamy base.
