French's Green Bean Casserole

In my younger years, I loved a heap of mac and cheese or mashed potatoes when presented with a spread of holiday sides.

But now, I couldn’t get enough of this green bean goodness even if I tried.

So, if you want to make everyone fall in love with the often-overlooked holiday side dish, this recipe is the key.

French’s Green Bean Casserole

Green bean casserole is a classic Thanksgiving staple that even non-green bean fans couldn’t do without.

The combination of green beans, cream of mushroom soup, cheese, and crispy French fried onions produces the most terrific tastes and textures!

The green beans may be the main feature of this casserole.

But the two things that make the dish a true star are melted cheese and crunchy French fried onions.

They really spruce up the rather bland green beans.

And here’s the kicker: this casserole is so easy to make, it’s almost embarrassing.

Your involvement is done in just 5 minutes. It’s mostly the oven that does the job.

French's Green Bean Casserole Ingredients


One thing I love the most about this recipe is how accessible, convenient, and inexpensive the ingredients are.

You only need 4 ingredients, which are so basic, it doesn’t make sense how it can produce a dish so holiday-worthy.

  • Green Beans – Many find canned green beans to be unpleasantly mushy, but I won’t judge if that’s what you use.

Just be sure that when using fresh or frozen green beans that you saute or blanch them in salted water first to soften them.

Frozen green beans also need to be thawed first.

My recipe calls for 2 (14.5-ounce) of canned green beans, which are equivalent to:

  • 1 1/2 pounds fresh green beans or
  • 16 ounces of frozen green beans
  • Condensed Cream of Mushroom SoupIt serves as a dressing to coat the beans, making them super creamy and delightful.

My preferred brand is Campbell’s (and no, this isn’t a paid advertisement) just because it has the best flavor and texture. Feel free to use your preferred brand.

Homemade cream of mushroom soup also isn’t that hard to make! I have a simple recipe for you in the tips section.

  • French Fried Onions – This is the reason why this casserole is called “French’s green bean casserole!” This show-stopping, crispy-crunchy topping makes all the difference. 
  • Shredded Cheddar Cheese – Shred the cheese yourself for maximum melt! But if you just don’t have the time, I won’t judge. I like to use those pre-shredded bags of cheese, too, from time to time.

Tips for the Best Casserole

  • You can use either fresh, frozen, or canned green beans for the recipe depending on your texture preference. Fresh ad frozen beans are crunchier, while canned beans are softer.
  • If you use fresh or frozen beans, either blanch or saute them beforehand to soften them. This’ll take about 8 minutes for fresh beans and 5 for frozen.
  • Add a can of chopped water chestnuts for extra crunch. This’ll also extend the servings of the casserole.
  • Speaking of more crunch, bacon bits will also wonderfully do the job.
  • My recipe calls for putting the onions on top, but you can also stir them into the casserole if you feel like it.
  • You can also stir all of the cheese (instead of just half), into the casserole. 
  • Don’t want to use the microwave? Here’s an alternative approach: bake the casserole, sans the toppings, for 30 to 35 minutes at 350 degrees Fahrenheit. Add the toppings and bake for 5 to 10 minutes more.
  • Feeding more hungry guests? Double the recipe and use a 9×13-inch casserole. Increase the baking time by 10 minutes.
  • This casserole isn’t just perfect for the holidays! Serve it any day with meatloaf or pork chops for a complete meal.
  • Or, make a whole meal just with side dishes. Dinner rolls, cranberry salad, and mashed potatoes all pair well with the casserole.

Storage and Make-Ahead Instructions

I doubt there’ll be any leftovers, but in case there is, cover them with foil or store them in an air-tight container. Refrigerate them for up to 3 to 5 days.

Reheat them in the microwave until warmed through. If you want the onions to crisp up once again, use either the oven or oven toaster.

To make ahead, microwave and assemble the ingredients in the casserole, but skip the toppings. 

Cover the casserole with plastic wrap and foil and refrigerate for up to 48 hours or freeze for up to two weeks.

If refrigerated, thaw at room temperature for 30 minutes, add the toppings, and bake as instructed.

If frozen, thaw the casserole in the fridge overnight, add the toppings, and bake as instructed.
