Many people reach for canned soups and frozen green beans when making casserole, but a homemade version delivers:

- Impressive presentation – A homemade casserole looks and tastes like it came from the chef’s table.
What You’ll Need: Ingredients Overview
Gathering quality ingredients is the first step toward a memorable casserole.
Fresh Green Beans
Choose bright, firm green beans with no brown spots. Trim the ends and blanch them briefly to keep color and crispness.
Mushrooms
White button or cremini mushrooms add earthiness. Sautéed mushrooms deepen flavor and blend beautifully with creamy sauce.
Onions
Yellow or sweet onions work best. Caramelizing them slowly brings out natural sweetness and adds rich flavor.
Cream Sauce Base
Instead of canned cream soup, you’ll make your own sauce using:
- Butter
- Flour (for thickening)
- Milk and/or heavy cream
- Garlic
- Black pepper
- Salt
This results in a silky, rich sauce without preservatives.
Topping Options
The classic topping is crispy fried onions, but you can also use:
- Panko breadcrumbs
- Parmesan cheese
- Crushed crackers or potato chips
Step‑by‑Step Instructions
Here’s how to make this casserole perfectly every time.
1. Prepare the Green Beans
Blanch fresh green beans in boiling salted water for 4–5 minutes, then plunge into ice water to stop cooking. This keeps them bright green and crisp‑tender.
2. Sauté the Aromatics
Heat butter over medium heat. Add finely chopped onions and cook until softened and caramelizing. Add minced garlic and mushrooms and continue to cook until mushrooms release moisture and brown slightly.
3. Make the Cream Sauce
Sprinkle flour over the vegetables and stir to coat. Slowly whisk in milk and heavy cream, making sure no lumps form. Simmer until thickened. Add salt, pepper, and a splash of Worcestershire sauce (optional) for depth.
4. Combine and Bake
Stir the blanched green beans into the creamy sauce. Transfer to a baking dish and spread evenly.
Top with crispy fried onions or your chosen topping. Bake in a 350°F (175°C) oven for 20–25 minutes, until hot and bubbling and the topping is golden brown.
Pro Tips for Perfect Texture
- Don’t overcook green beans before baking. They should be firm before going into the oven.
- Caramelize onions slowly ,this adds sweetness and depth.
- Use heavy cream sparingly to enrich without making the casserole too loose.
- Mix toppings ,try breadcrumbs + parmesan for extra crunch.
