How do you increase green bean casserole for 50 servings?

Here's how to scale up a classic green bean casserole recipe for 50 servings:

Ingredients (50 Servings):

* Green Beans: 10 cans (14.5 ounces each) or 10 pounds fresh green beans, trimmed and cut into 1-inch pieces

* Mushrooms: 10 cans (4 ounces each) sliced mushrooms, drained

* French Fried Onions: 5 large cans (12 ounces each)

* Cream of Mushroom Soup: 5 cans (10.75 ounces each)

* Milk: 4 cups

* Salt and Pepper: To taste

* Optional: 1/2 cup grated Parmesan cheese

Instructions:

1. Pre-heat Oven: Preheat oven to 350°F (175°C).

2. Prepare Green Beans: If using canned green beans, drain them well. If using fresh green beans, steam or blanch them until tender-crisp.

3. Combine Ingredients: In a very large bowl (or multiple large bowls), combine the drained green beans, mushrooms, cream of mushroom soup, and milk. Stir well to combine.

4. Season: Season with salt and pepper to taste. You might need a little more seasoning for a larger batch.

5. Transfer to Baking Dishes: Divide the mixture evenly among large baking dishes (you might need 5-6 depending on size).

6. Top with Onions: Sprinkle the French fried onions evenly over the top of each dish.

7. Bake: Bake for 20-25 minutes, or until heated through and the onions are golden brown.

8. Serve: Let cool slightly before serving.

Tips for Scaling Up:

* Equipment: Use large mixing bowls and baking dishes to accommodate the larger quantities.

* Even Distribution: Make sure the green bean mixture and onions are evenly distributed throughout the dishes for consistent results.

* Baking Time: Keep an eye on the casserole as it bakes to ensure it doesn't overcook or burn.

* Freshness: If using fresh green beans, make sure they are blanched properly to maintain their vibrant color and texture.

* Storage: The casserole can be assembled ahead of time and refrigerated for up to 24 hours. Just bake it directly from the refrigerator, adding a few minutes to the baking time.

Additional Notes:

* You can easily customize this recipe by adding additional ingredients like chopped onions, garlic, or even cooked crumbled bacon.

* Consider using a stand mixer with a paddle attachment to help thoroughly combine the ingredients.

* Remember, these are general guidelines, adjust the seasoning and ingredients to your personal preferences.
