how to make Easy Classic Green Bean Casserole
Start by preparing the beans and the mushroom sauce. Boil the green beans until just tender, then drain them well. Cook onion and garlic until soft, then add mushrooms and let them release their juices. Add the broth and soy sauce and let the sauce simmer to deepen the flavor. Stir in nutritional yeast for a mild cheesy note, and season with salt and pepper. Mix the beans with the mushroom sauce so the beans soak up the flavor. Put the mix into a baking dish and spread breadcrumbs over the top. Bake until the crumbs are golden and the sauce bubbles.

FAQs
Q: Can I use canned green beans?
A: Yes. If you use canned beans, drain them well and skip the boiling step. Add them to the sauce and bake as directed. They will be softer, so watch the bake time.
Q: Can I make this ahead of time?
A: Yes. Prepare the casserole up to the point of baking. Cover and refrigerate for up to 24 hours. Bake when ready. For longer hold, keep the crumbs off until just before baking.
Q: Is this recipe vegan?
A: Yes. This version uses no dairy or meat. It uses nutritional yeast for a cheesy flavor and olive oil for richness.
Q: How do I make the top extra crispy?
A: Toast breadcrumbs first in a pan with a little olive oil. Add them to the top right before baking. You can broil for 1-2 minutes at the end, but watch closely so they do not burn.
Q: Can I add cheese?
A: If you are not vegan, you can stir in grated cheese into the sauce or sprinkle cheese on top before baking. Use a mild melting cheese so it blends well.
Q: What is a good substitute for nutritional yeast?
A: For a non-vegan option, grated Parmesan or a small amount of cream can add richness. Nutritional yeast adds a cheeselike flavor without dairy.
Q: How can I make it low sodium?
A: Use low-sodium vegetable broth and reduced-sodium soy sauce. Taste the sauce before baking and add salt only if needed.
Q: Can I use frozen green beans?
A: Yes. Thaw and drain frozen beans, or cook them briefly before using. Frozen beans can add extra water, so dry them well.
