SWEET AND CHEESY ONION CASSEROLE {PRINT THIS RECIPE}
3 tablespoons butter
2 tablespoons olive oil
8-9 large, sweet onions, medium diced
1 ½ teaspoons salt
½ teaspoon black pepper
1 tablespoon garlic powder
2 tablespoons granulated sugar
⅛ teaspoon freshly grated nutmeg
3 tablespoons flour (plus more if needed)
8 ounces, of shredded Monterey Jack cheese
8 ounces, of shredded sharp cheddar cheese
1 cup panko bread crumbs
¼ cup melted butter
-Preheat the oven to 350 degrees.
-Add the butter and olive to a large Dutch oven over medium/high heat to melt.
-Add in the onions, salt, pepper, garlic powder, and nutmeg. Cook, stirring occasionally until the onions become soft and slightly translucent (about 10-15 minutes).
-Stir in the granulated sugar and allow it to melt (about 2-3 minutes).
-Stir in the flour. Stir and cook for an additional few minutes. The onions should become thick and pasty at this point. If not, add a little bit more flour.
-Remove from the heat and stir in the grated cheeses until melted.
-Carefully spoon the onion cheese mixture into a round casserole dish that has been lightly sprayed with cooking spray.
-Cover the top of the onions with the bread crumbs and drizzle the top with the melted butter.
-Bake in a preheated oven for 35-40 minutes.
-Remove from the oven and allow it to cool about 10 minutes before serving.
I wish I had additional pictures to share of this heartwarming classic from around our holiday table but unfortunately, I don't.
We always dig in too fast, and before you know it it's just a loving distant memory. It's certainly a dish we'll dream sweet dreams of while napping on the couch, after the large holiday feast.
Having said that, don't save this recipe just for the holidays. It goes well during the summer with a big steak off the grill too. Oh, hey now. Doesn't that sound tasty?

O.K., I'll confess that I don't eat onions save for some finely chopped shallots in a salad but your casserole does look warm and inviting. I'm betting your tile will look just as lovely.

I'm going to make a confession here: I only order patty melt sandwiches at restaurants and diners for one reason - the cooked sweet onions and cheese that go on top. You have just given me a VAT of that awesomeness!
