π¨βπ³ Step-by-Step Instructions
π₯ Step 1: Prepare the Green Beans
1οΈβ£ Start by trimming the ends of the fresh green beans and cutting them into bite-sized pieces.
2οΈβ£ In a large pot, bring water to a boil. Add the green beans and cook them for about 3β4 minutes until tender but still slightly crisp.
3οΈβ£ Drain the green beans and set them aside.
π‘ Pro Tip: Blanching the green beans before baking helps keep their vibrant green color and crisp texture.
π Step 2: Make the Mushroom Sauce
1οΈβ£ In a large saucepan, melt 1 tablespoon of butter over medium heat.
2οΈβ£ Add the cream of mushroom soup, milk, garlic powder, and onion powder. Stir to combine and bring the mixture to a gentle simmer.
3οΈβ£ Add soy sauce, salt, and pepper, then continue to stir until the sauce is smooth and creamy.
4οΈβ£ Taste and adjust the seasonings to your preference.
π‘ Pro Tip: If you prefer a richer sauce, add a splash of heavy cream for extra creaminess. πΆ
π₯¬ Step 3: Combine the Green Beans and Sauce
1οΈβ£ In a large mixing bowl, combine the cooked green beans and the mushroom sauce. Stir until the green beans are well-coated in the creamy sauce.
2οΈβ£ Transfer the mixture to a greased 9Γ13-inch baking dish.
π§ Step 4: Add the Topping
1οΈβ£ Sprinkle fried onions evenly over the top of the casserole.
2οΈβ£ If youβre using shredded cheddar cheese, sprinkle it on top of the fried onions for a cheesy, melty finish. π§
π‘ Pro Tip: For extra flavor, add a few more fried onions for a crunchier topping. You can also use French fried onions for a classic touch!
π₯ Step 5: Bake the Casserole
1οΈβ£ Preheat your oven to 350Β°F (175Β°C).
2οΈβ£ Bake the casserole for about 25β30 minutes, until the top is golden brown and bubbly.
