Instructions
Preheat oven to 375° F.
Rinse and trim green beans. Cook according to your texture preference. For a more crisp green bean, boil for 5 minutes. For a softer green bean, boil for 10 minutes or cook in the Instant Pot for '0' minutes. Once cooked, place green beans in a 9x9 baking dish.
Sauce
Melt butter in a saucepan over medium-low heat. Whisk in flour and continue whisking until the mixture is smooth and bubbly, making a roux.
Remove the saucepan from heat and slowly add in chicken broth and milk, whisking continuously. Whisk until combined, then return to the heat. Add in 2 tbsp chopped onion and all the mushrooms.
Bring to a gentle boil and simmer for 5-10 minutes, until thickened. Mixture will continue to thicken as it cools. Salt and pepper to taste. Stir in shredded cheese until melted.
Crispy Onion Topping
Saute onions in 1 tbsp of butter until they are soft. Set onions aside.
In the same pan, add remaining butter and saute the panko until browned. Stir the onions and panko together.
Time to assemble! Stir the creamy sauce and green beans together and place in your baking dish. Sprinkle the crispy onion topping on top.
Place in the oven, uncovered, and bake for 25-30 minutes, until the top is golden brown. Serve warm.
