Ingredients
For the Green Beans:

1 teaspoon salt (for blanching water)
For the Creamy Cheese Sauce:
2 tablespoons butter
1 small onion, finely chopped
3 cloves garlic, minced
2 tablespoons all-purpose flour
1 1/2 cups milk (whole milk preferred)
1/2 cup heavy cream
1 cup shredded cheddar cheese
1/2 cup grated parmesan cheese
1/2 teaspoon black pepper
1/2 teaspoon paprika
Salt to taste
For Topping:
1 1/2 cups crispy fried onions
1/2 cup shredded mozzarella or cheddar cheese (optional extra topping)
Instructions
Preheat oven to 375°F (190°C) and lightly grease a medium baking dish.
Bring a large pot of salted water to a boil and blanch green beans for 3–4 minutes until bright green and slightly tender.
Drain beans and immediately rinse under cold water to stop cooking. Set aside.
In a large skillet, melt butter over medium heat and sauté chopped onion for 3–4 minutes until soft.
Add minced garlic and cook for about 30 seconds until fragrant.
Sprinkle flour into the skillet and stir continuously for 1–2 minutes to form a light roux.
Slowly whisk in milk and cream, cooking until the mixture thickens into a smooth sauce.
Stir in cheddar cheese, parmesan, pepper, paprika, and salt until melted and creamy.
Combine green beans with the cheese sauce and transfer mixture to the prepared baking dish.
Top with crispy onions and optional extra cheese, then bake for 25–30 minutes until bubbly and golden.
Tips
Blanching green beans helps maintain their bright color and crisp texture.
Use freshly shredded cheese for smoother melting and better flavor.
Stir sauce constantly when adding milk to prevent lumps.
If sauce becomes too thick, add a splash of milk before baking.
Taste and adjust seasoning before assembling casserole.
Add half the crispy onions during baking and the rest at the end for extra crunch.
Avoid overcooking beans before baking to prevent mushy texture.
Use whole milk or cream for the richest sauce consistency.
Let casserole rest for 5 minutes after baking to help it set.
Broil for 1–2 minutes at the end for a crisp golden topping.
Variations
Add sautéed mushrooms for a classic flavor combination.
Mix in cooked bacon pieces for a smoky twist.
Use Gruyère or Swiss cheese instead of cheddar for deeper flavor.
Add red chili flakes for a subtle spicy kick.
Replace half the green beans with broccoli florets.
Make it gluten-free by using gluten-free flour and topping.
Add crushed crackers or panko for extra crunch.
