My Mother In Law's Slow Roasted Cheesy Green Bean Casserole

My Mother-in-law is known for her cheesy baked green bean casserole!

The crispy cheesy crust provides the perfect textural contrast which makes the whole dish irresistible!

Cheesy Baked Green Bean Casserole

Not going to lie, my Mother-in-law's cheesy green bean casserole is the bomb!

It's legit the only green bean casserole recipe that you'll ever need because it is complete perfection.

So what makes hers different from the rest?

Well, first of all it's loaded with sharp cheddar so you know it's going to be good.

Second of all, it's slow roasted which makes it very different than your traditional versions.

The slow roasting creates a creamy, jammy, melt-in-your-mouth texture that is completely irresistible.

The top has a crispy cheesy onion crust that provides the perfect textural contrast.

How to make Cheesy Green Bean Casserole

The one thing that I absolutely love about this green bean casserole (besides the flavor!) is how easy it is to make!

Like most traditional casserole recipes, we'll be relying on canned goods.

This one requires four cans of french cut green beans (drained), one can of cream of mushroom soup, one can of cream of celery soup, 1 block of grated sharp cheddar (I LOVE TILLAMOOK!), and one package of French's crispy fried onions.

Before you begin, preheat your oven to 375F degrees.

Get a large bowl and mix together the drained green beans, the soups, half of the cheddar and half of the fried onions. Add about ¼ tsp of salt and stir to combine.

Dump this mixture into a greased baking dish.

Now add the remaining cheddar and spread it evenly across the top. Top the cheddar with the remaining crispy fried onions and put it in the oven.

Let the casserole bake for an hour.

I like to turn it half way through just so the crust can develop an even golden-brown color and crispy texture.

Note: If your oven runs hot and you notice the top burning, simply cover with tinfoil and continue to bake. But to be honest, we like the top extra crispy!
