This was such an enormous hit we are all still talking about it!! This is one of the best things I've ever made, and for as complex as it tastes it really wasn't that much harder to cook than regular green bean casserole. It was also amazing leftover. We had a ham at our thanksgiving and it was great diced up in here too! All of us forgot mushrooms were in here or cajun seasoning, it somehow all blends together into an umami-rich dish!
The only change I would make which was in a lot of the comments is there is an abundance of sauce- so next time I would halve the sauce or double the veggies (the sauce could make a shoe taste delicious so I'd pick the latter!).
Ingredients:
Nonstick cooking spray
2.5 lbs haricots verts or French green beans, trimmed into 1 inch pieces
1 lb hen of the woods mushrooms (we got a wild mushroom mix with cremini, oyster, etc) cut into bite size pieces
2 large shallots, halved lengthwise and thinly sliced into half moons
4 garlic cloves, minced
2 tbsp EVOO
Salt and Pepper
2 tbsp unsalted butter
2 tbsp AP Flour
1 quart heavy cream or half and half (we did half heavy cream and half whole milk and were super glad with this combo)
1 tsp cajun seasoning
1/2 tsp each onion powder, garlic powder, chicken bouilion base
1/4 tsp ground nutmeg
1 3/4 cups shredded or grated parmesan
1 cup panko breadcrumbs
2 cups fried onions
Directions:
1. Heat oven to 400. Coat a 9x13 pan with nonstick cooking spray.
2. On a baking sheet combine green beans, mushrooms, shallots, garlic, EVOO, salt, pepper, and 3 tbsp of water. Roast for 45 minutes or until beans are soft.
3. Meanwhile, in a large saucepan over medium low heat, melt the butter then add the flour. Cook for 1-2 minutes until golden in color, whisking constantly.
4. Add heavy cream and whisk until it starts to thicken, about 6-8 minutes (ours took longer). Add seasonings and 1 1/2 cups parmesan, continuing to whisk constantly. Taste and adjust seasonings.
5. Add the roasted veggies to the mix and combine. Pour into the baking dish.
6. In a medium bowl, combine remaining 1/4 cup parmesan, bread crumbs and fried onions. Spread evenly over the top of the casserole.
7. Set the broiler to high, broil until brown and bubbly (don't walk away!), about 1-2 minutes. Serve hot.
