Instructions

Preheat the oven to 350°F (175°C). Blanch the green beans in boiling water for 3–4 minutes until tender-crisp, then transfer to ice water. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add garlic and onion, cooking 3–4 minutes until fragrant and translucent.
Sprinkle flour over the onions and garlic, stirring for 1–2 minutes to form a roux. Gradually whisk in vegetable broth and heavy cream until thickened. Add salt, pepper, and thyme. Stir in shredded cheese if desired.
Add the green beans to the sauce, tossing to coat evenly.
Transfer the mixture to a greased 9×13-inch baking dish and smooth the top.
Sprinkle crispy fried onions evenly over the casserole. Bake uncovered for 25–30 minutes until bubbly and golden brown.
Allow the casserole to cool slightly before serving.

Notes

Fresh green beans give the best texture, but frozen can be used if thawed and drained.
Make-ahead tip: Prepare the mixture a day in advance and refrigerate; add onions just before baking.
Adjust garlic to taste; roasting it adds a sweet, deep flavor.
For extra crunch, use homemade fried onions or toasted breadcrumbs.
