What You’ll Need
So what’s in this dish? The sour cream sauce is made without any canned soup, but it’s just as easy as any other casserole recipe. Here’s what you’ll need:
- Butter: Salted or unsalted, it’s up to you.
- Onion: Just a small amount of chopped onion adds a ton of flavor.
- Garlic: Freshly minced garlic is the best, but garlic powder will also work.
- Flour: A spoonful of flour thickens the cream sauce.
- Frozen Green Beans: I love the french-style green beans for this. Make sure they’re thawed and drained.
- Seasonings: Salt, pepper, and a pinch of nutmeg. Don’t worry – the nutmeg enhances the creamy sauce, but it won’t taste like gingerbread!
- Sour Cream: Creamy sauces are often made with milk, but the thick and tangy taste of sour cream really brings out the best in this recipe.
- Bacon Bits: Cook and crumble a few strips of bacon, or buy pre-cooked bacon at the store and chp it finely.
- Cheese: Shredded cheddar is my go-to! If you want to change it up, you could try using another strongly-flavored cheese like colby jack.
- Cornflakes: Crumbled for topping.
- Parmesan: For serving.
How to Make This Cheesy Green Bean Casserole
The creamed green bean base for this casserole is quick to make, and comes together in one pan for a simple cleanup.
- Get the Oven and Baking Dish Ready. You’ll want to start off by preheating the oven to 400°F. Spray a 1-quart, oven-safe baking dish with cooking spray, or grease it with oil.
- Cook the Onions, Garlic, and Green Beans. Next, melt a tablespoon of butter in a saute pan, and cook the onions and garlic in the melted butter for 2 minutes. Stir in the green beans, and cook all three for another 4 minutes, stirring occasionally.
- Make the Roux. Use a spatula or wooden spoon to scoot the green beans to the edges of the pan. In the center of the pan, melt another tablespoon of butter. Once it melts, sprinkle the flour, nutmeg, salt, and pepper on the melted butter, and stir gently to combine. Cook for 1 minute.
- Add the Sour Cream. Scoop your sour cream into the pan, and stir everything well to combine.
- Assemble the Casserole. Pour the hot green bean mixture into your greased baking dish. Sprinkle the bacon bits and cheese on top. Then melt the last tablespoon of butter and pour it over the cornflakes, toss to combine, and spread the buttered cornflakes over the casserole.
- Bake. Transfer the baking dish to the oven, and let it bake for 20 minutes. (Cover the casserole with foil if the cornflakes are browning too quickly.)
- Enjoy! Take the green beans out of the oven, and grate some fresh parmesan cheese over the top before serving.
Tips and Tricks
Not only is this a scrumptious recipe, it’s also easy to make, especially when you know a few helpful tips and tricks. Here are my best pieces of advice for making this yummy dish.
- Using Foil: You can cover the baking dish with foil for the first 10 minutes of baking time, so that the cornflakes don’t brown too much. Then, remove the foil for the final 10 minutes, to get a perfectly crispy result.
- Topping Options: Lays potato chips are a great alternative to cornflakes! Just omit the final tablespoon of butter, since the chips don’t need it. French fried onions are also a great choice.
- About the Beans: I use frozen green beans, but you can substitute canned or fresh green beans if you prefer. Just make sure to drain whatever kind you use well, before adding them to this recipe, so the cheesy green bean casserole doesn’t get watered down.
I would usually serve a dish like this as part of a holiday spread or family feast. You can also serve as an easy weeknight meal with…
- Chicken: One of our hands-down favorite dinners is this easy Baked Honey Mustard Chicken. It’s loaded with sweet and tangy flavor, and goes with everything.
- Salmon Patties: There’s just something about Crispy Salmon Patties and green beans – a savory, healthy combo that is familiar and yet different from a routine meal.
- Ham: Get that extra ham you bought when they were on sale out of the freezer, and let it become the basis for a few hearty meals! This Crockpot Ham recipe is a great, hands-off way to cook a ham.
- Turkey: And of course, if it’s the holidays, these creamed green beans go perfectly with a gorgeous Thanksgiving Turkey!
How to Store and Reheat Your Leftovers
Store leftovers in an airtight container in the refrigerator for up to 5 days.
Reheat in the microwave, or better yet, the oven. A quick bake at 400°F will not only warm up the casserole, it will also re-crisp the cornflake topping. Win-win!
Freezing and Making Ahead
Creamed green beans do not freeze well, so I recommend enjoying cheesy green bean casserole fresh. However, even though it doesn’t freeze well, you can still make it ahead!
To do this, fully assemble the dish, but don’t bake it. Instead, cover it with foil and refrigerate for up to 48 hours. Remove it from the fridge for 1 hour before baking, to let it come to room temperature. Then bake according to the recipe directions.
