  • 1 can mushroom soup
  • 1 can French fried onion rings

Instructions

  1. Preheat the oven to 325°F (163°C).

  3. Pour the mushroom soup over the green beans.
  4. Spread the French fried onion rings on top of the soup-covered beans.

Tips & Substitutions

For a creamier texture, consider adding a splash of milk or sour cream to the mushroom soup before pouring it over the beans. If you prefer a crispy topping, try using panko breadcrumbs in place of French fried onion rings. This dish can also be made using fresh green beans if you blanch them first. For added flavor, season with garlic powder or onion powder.

Serving Suggestions

This green bean casserole pairs beautifully with roasted turkey or glazed ham, making it a perfect side for holiday meals. Consider serving it alongside mashed potatoes or a fresh salad for a well-rounded dinner. For a vegetarian option, make sure to choose a mushroom soup that is free from meat-based broth.

Storage & Reheating

To store leftovers, let the casserole cool completely before transferring it to an airtight container. It can be refrigerated for up to 3 days. When reheating, place it in the oven at 325°F (163°C) for about 15-20 minutes, covered with foil to prevent drying out, or microwave individual portions until heated through.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can assemble the casserole a day in advance. Just cover it tightly with foil and store it in the refrigerator. When ready to bake, allow it to sit at room temperature for about 30 minutes before placing it in the oven to ensure even cooking.

What can I use instead of French fried onion rings?

If you don't have French fried onion rings, you can substitute with crushed potato chips or make your own by frying thinly sliced onions until golden brown. Alternatively, panko breadcrumbs mixed with melted butter can add a nice crunch on top.

Is this recipe suitable for vegan diets?

To make this green bean casserole vegan, use a plant-based mushroom soup and check the ingredient list of the French fried onion rings to ensure they are dairy-free. This way, you can enjoy a delicious vegan version of this classic dish.
