Ingredients:
– 1 medium onion

– 3/4 cup (45g) panko breadcrumbs
– 1/2 teaspoon salt
– 1/4 teaspoon ground black pepper
– 1 large egg
– 1 Tablespoon (15ml) milk
– 1 Tablespoon + 1 teaspoon salt, divided
– 1 pound fresh green beans, rinsed, ends trimmed, and halved
– 2 Tablespoons (28g) unsalted butter
– 8 ounces sliced mushrooms
– 1/2 teaspoon ground black pepper
– 2 cloves garlic, minced
– 2 Tablespoons (15g) all-purpose flour
– 3/4 cup (180ml) chicken or vegetable broth
– 1 and 1/4 cups (300ml) half-and-half
How to Make Creamy Green Bean Casserole from Scratch
Step 1: Preheat the Oven
Preheat your oven to 450°F (232°C). Line a large baking sheet with parchment paper or a silicone baking mat. Set aside.
Step 2: Prepare the Onion Topping
- Thinly slice the onion and separate the slices.
- In one bowl, pour flour; in another bowl, mix panko breadcrumbs with salt and pepper; in a third bowl, whisk together egg and milk.
- Using one hand for dry ingredients and one hand for wet ingredients:
- Dip onion slices into the flour.
- Then dip into the egg mixture.
- Finally, coat well with panko breadcrumbs before placing them on the baking sheet.
- Bake until golden brown for about 20 minutes, flipping twice during baking. Set aside after baking.
Step 3: Blanch the Green Beans
Reduce oven temperature to 400°F (204°C).
* Bring a gallon of water with 1 tablespoon of salt to boil in a large saucepan.
* Add green beans and boil them for 5 minutes.
* Fill a large bowl with ice water nearby. Drain beans and immediately transfer them into ice water to stop cooking. Drain again once cooled.
Step 4: Make the Gravy Sauce
In an ovenproof skillet over medium-high heat:
* Melt butter, then add mushrooms along with 1 teaspoon salt and pepper. Cook until mushrooms release moisture—about 5 minutes.
* Stir in minced garlic; cook for another 2 minutes.
* Sprinkle flour over mushrooms; stir until combined. Add chicken broth and simmer for about 3 minutes.
* Reduce heat to medium-low; slowly add half-and-half while stirring occasionally until thickened—about 10 minutes.
Step 5: Combine Ingredients
Remove from heat:
* Add about one-quarter of baked onions along with all blanched green beans. Stir thoroughly to combine everything well.
* If not using an oven-safe skillet or transferring to a casserole dish, move mushroom/gravy mixture into a greased dish now.
Step 6: Bake the Casserole
Top the mixture with remaining onions:
* Bake until bubbling around edges—approximately 15 minutes.
* Remove from oven before serving warm.
Step 7: Storing Leftovers
Leftovers can be stored in an airtight container in the refrigerator for up to four days. Reheat as desired.

Common Mistakes to Avoid

-
Using Frozen Green Beans: Fresh green beans bring a better texture and flavor. If you use frozen ones, they may release excess water, making the dish soggy.

-
Not Seasoning Properly: Overlooking salt and pepper can result in a bland casserole. Always taste your sauce and adjust seasoning before assembly.
-
Using Too Much Flour for Thickening: Adding excess flour can make the gravy too thick and pasty. Measure your flour accurately for the right consistency.
-
Rushing the Baking Time: Baking allows flavors to meld and enhances texture. Don’t skip or rush this step; it’s crucial for achieving that perfect finish.
-
Not Storing Properly: Improper storage can lead to spoilage. Ensure your leftovers are in an airtight container to maintain freshness.
