How to Make Green Bean Casserole Homemade
1. Caramelize the Onions and Mushrooms
- Heat 4 tablespoons butter in a large skillet over medium-high.
- Add chopped onion and cook, stirring often, for 7-8 minutes until golden and tender.
- Stir in mushrooms and cook 4 more minutes.

2. Make the Creamy Sauce
- In the same skillet, add remaining 4 tablespoons butter and melt over medium.

3. Prep the Green Beans
- Bring a large pot of water to a boil. Add green beans and cook for 6-7 minutes until just tender.

4. Assemble the Casserole
- Preheat oven to 350°F (175°C).
- Stir the onion-mushroom mixture into the cream sauce.
- Add green beans and toss to coat. Add Parmesan if using.
- Pour into a 9x9-inch (or similar) baking dish.

5. Bake and Top
- Bake for 25 minutes or until bubbling.
- Remove from oven, sprinkle fried onions evenly over the top.
- Bake 5 more minutes until onions are golden and crispy.

6. Serve
- Let cool a couple minutes, then serve hot and creamy!

Tips & Variations
- Short on time? Use high-quality frozen green beans (thawed and drained).
- Canned green beans? They'll work in a pinch; just skip the boiling step.
- Add-ins: Stir in cooked bacon, sautéed bell peppers, or a handful of shredded cheese for your own twist.
- Make ahead: Assemble up to the point of adding fried onions, cover and refrigerate up to 2 days. Add onions and bake just before serving.
