Why You’ll Love This Campbells Green Bean Casserole

This dish is more than a holiday side—it’s a weeknight lifesaver, a potluck hero, and the easiest way to wow a crowd without stressing. Here’s why it’ll win over your table:

• It’s fast: You only need 15 minutes of prep before the oven takes over.

• It’s nostalgic: Campbell’s cream of mushroom soup brings that classic flavor we grew up with.
• It’s picky-eater friendly: Even the veggie-adverse tend to cave for crispy fried onions.

Ingredients You’ll Need

The Casserole Base

• 1/2 cup milk (whole milk gives the creamiest texture)
• 1/4 tsp black pepper
• 1 tsp soy sauce (mild umami boost—trust me on this one)
• 1 can condensed cream of mushroom soup (Campbell’s for that iconic taste)
• 4 cups green beans (fresh, frozen, or canned)

The Crispy Topping

• 1 1/3 cups crispy fried onions (French’s is traditional!)

How to Make Campbells Green Bean Casserole

Let’s keep this simple, cozy, and totally doable—even if your brain clocked out an hour ago.

Step 1: Prep the Green Beans

• Frozen? Thaw and drain.
• Fresh? Trim, cut, blanch, drain.
• Canned? Just drain well.
  Preheat your oven (or air fryer!) to 350°F.

Set aside 1/3 cup of your fried onions for topping later. Hide them if needed—someone will try to snack on them.

Step 2: Make the Creamy Base

In a large bowl, whisk together the cream of mushroom soup, milk, and soy sauce.
The soy sauce adds depth without stealing the show—think of it as the quiet friend who always knows exactly what to say.

Step 3: Mix It All Together

Fold in the green beans, black pepper, and 2/3 cup fried onions.
Stir gently—you want those onions to stay crispy for their grand finale.

Step 4: Bake Until Bubbly

Spread into a 9×9-inch casserole dish and bake for 25 minutes (or 10 minutes in an air fryer).
You’re looking for bubbly edges and a heavenly aroma.

Step 5: Add the Crispy Topping

Give the casserole a light stir, sprinkle on the remaining fried onions, and bake 5 more minutes (2 minutes in the air fryer).
This final step? It’s what turns “yum” into “YAAAAS.”

How to Make Campbells Green Bean Casserole in the Slow Cooker

If your oven is packed to the brim (hello, holiday chaos!) or you simply love a true set-it-and-forget-it dish, you’ll be happy to know this Campbells Green Bean Casserole works beautifully in the slow cooker. The flavor stays creamy and comforting, and it frees up precious oven space.

Slow Cooker Instructions

1. Prep the green beans just as you would for the original recipe:
   • Frozen → thaw and drain
   • Fresh → trim, cut, and blanch
   • Canned → drain well
2. In a bowl, whisk the cream of mushroom soup, milk, and soy sauce until smooth.
3. Fold in the green beans, black pepper, and 2/3 cup of fried onions.
4. Transfer everything into a lightly greased 4–6 quart slow cooker.
5. Cover and cook on:
   • Low for 4–5 hours, or
   • High for 2–3 hours
     until the mixture is hot and bubbling gently around the edges.
6. When ready to serve, sprinkle the remaining crispy fried onions over the top.
   Tip: If you like them extra crispy, toast them for a minute in a skillet or, if your slow cooker insert is oven-safe, pop it under the broiler for 2 minutes.

Slow Cooker Tips

• Keep the lid off for the last 15 minutes if you want the sauce a little thicker.
• Switch to Warm once cooked — this casserole holds beautifully on a buffet table.
• Never add the final onions early! They lose their crispiness (and we definitely want that crunch).

This method is perfect when you want the same creamy, nostalgic flavor of the classic casserole, but with the convenience of hands-off cooking.

Tips for the Best Results

• If your sauce looks thick: Don’t stress—it’s just extra comfort waiting to happen.
• Fresh beans: Blanch just long enough to keep them bright and snappy.
• Doubling the recipe: Totally easy—just use a 9×13 dish and add a few minutes to the bake time.
• Serving idea: Pair with roasted chicken, baked ham, or honestly? A big cozy sweater and a spoon.

And here’s a little personal confession: this exact recipe saved me during a week when my calendar looked like a game of Tetris… but with deadlines. Tossing everything together and letting the oven work its magic felt like winning a tiny battle.
