- 1/4 cup grated Parmesan cheese
- 1 (6oz) container crispy fried onions
- seasoning to taste (garlic powder, black pepper)
Instructions
-
Preheat oven to 350° F and grease a 1½-quart baking dish (9×9 or 7×11).

-
Bake on the center rack for 25 minutes. Add the crispy fried onions on top and bake 5 more minutes, or until the onions are crisp and golden.
Notes
- Feeding a crowd? Double the ingredients and use a 9×13 baking dish. Mix about a quarter of the crispy onions into the green bean mixture before baking and add the remaining onions on top during the final five minutes. You may need to increase the initial bake time by about 5 minutes.
- This recipe also works well with thawed broccoli or other vegetables that pair with Alfredo sauce.
- To make it heartier, stir in shredded rotisserie chicken or cooked sausage before baking.
