Caramelize the onions (optional). Caramelizing the onions will give some amazing bonus flavors, but it’s not required if you’re short on time. If you’ve never caramelized onions, this article tells you how to do it. You’ll also find the instructions in the recipe card at the bottom of the post.
Make the sauce. To make your sauce, add the remaining butter and chopped mushrooms to the cooking onions. Cook until the mushrooms have softened and released their water. Add the salt, pepper, Italian seasoning, and fresh garlic. If the mixture appears dry, add an additional 1-2 tablespoons of butter with the onions and mushrooms.
Assemble and Bake. Once you’ve reached the assembly stage, your casserole is practically finished! Preheat the oven to 375 degrees Fahrenheit and spray a large 9×13 inch baking dish with non-stick cooking spray. Mix together the corn, green beans, half of the cheese, and browned meat with the homemade sauce. Transfer to your prepared baking dish
