Place the dish in your preheated oven and bake uncovered for 30 minutes. The cheese will melt and the edges become bubbly which signals the flavors have melded together
Add crispy topping:
Carefully remove the dish and sprinkle the remaining half cup of French fried onions evenly over the surface. Return to the oven for five more minutes so the onions turn golden and crisp
Finish and serve:
Once finished take the casserole from the oven. Top generously with chopped parsley before serving hot for the brightest flavor and color contrast
French fried onions are my personal favorite ingredient in this dish. They provide that satisfying bite and finish which always impresses my guests. My son once snuck extra onions from the can before dinner just because he could not resist.
