Introduction: Cheesy Onion Casserole: Best Thanksgiving Side Dish Ever!

No Thanksgiving is complete without a casserole and this one is literally as easy to make as it is to eat. With only a few ingredients and 30 minutes cooking time, it can easily be made between all the other more complicated Thanksgiving dishes.

Thanksgiving is a day of total hedonism where we gorge ourselves silly and have enough left overs for an army! Cheesy Onion Casserole, a family favorite, is so delicious the left overs are always fought over and we have to evenly and judiciously distribute or else the army is at war.

Simple and tasty dish.

This a go to holiday dish at my house. I keep misplacing the recipe so I have to come on here and refresh my brain. I add a little wine and beef stock when sauteing the onions and it takes just like french onion soup in a pan! LOVE LOVE this recipe.

I add a box of croutons to the mix before baking.

can it be made ahead without getting too soggy?

Interesting recipe! I've never seen something like this before, but it sounds scrumpious!

It sounds kind of like A chicken version of French onion soup, only in a casserole.

Why does the bread look toasted before it is added to the baking dish? Was this step skipped in the instructions?

The bread toasted during 1st 15 minutes. The picture shows the bread being pushed down under the sauce and topped with the remaining cheese and baking for 15 more minutes.

What does the bread do for this recipe? Soggy bread of any kind just grosses me out.........Can it be made without the bread topping?
