- 1/2 small onion, finely chopped (about 1/4 cup)
- 1 small garlic clove, minced
- 1/2 cup low-sodium vegetable broth
- 1/4 cup low-fat milk or unsweetened oat milk
- 1 teaspoon cornstarch mixed with 1 tablespoon cold water
- 1 tablespoon olive oil or unsalted butter
- 1/3 cup plain breadcrumbs or panko
- 1 teaspoon olive oil for topping
- 1/4 teaspoon dried thyme or 1/2 teaspoon fresh chopped
- Freshly ground black pepper, to taste
- Optional: 1 to 2 tablespoons grated low-sodium Parmesan or nutritional yeast

Step-by-Step Recipe

- Preheat the oven to 375 F and lightly oil a small 1-quart baking dish or an oven-safe skillet.
- If using fresh beans bring a small pot of water to a boil. Add the beans and cook 4 to 6 minutes until just tender. Drain and set aside. For softer beans simmer 6 to 8 minutes.
- In a small skillet warm 1 tablespoon olive oil over medium heat. Add the onion and cook 3 to 4 minutes until soft.
- Add the mushrooms and cook 4 to 5 minutes until they release liquid and soften. Add the garlic and cook 30 seconds more.
- Stir in the low-sodium broth and milk and bring to a gentle simmer. Whisk in the cornstarch slurry and simmer 1 to 2 minutes until the sauce thickens. Season with black pepper and thyme.
- Add the blanched green beans to the sauce and mix to coat. Transfer everything to the prepared baking dish and spread evenly.
- Mix breadcrumbs with 1 teaspoon olive oil and a pinch of thyme. Sprinkle evenly over the casserole and add the optional grated Parmesan if using.
- Bake 12 to 15 minutes until the topping is lightly golden and the casserole is bubbly. For a softer top cover loosely with foil and bake 10 minutes then uncover for the last 2 minutes. Let rest 3 minutes before serving.

FAQ
Can I use canned green beans?▶
Yes. Rinse canned green beans well and heat briefly. They will be softer and faster to use in this small-batch casserole.
Is there a stovetop-only option?▶
Yes. Skip the oven and simmer the topped casserole on low with a lid until warmed. For a crisp top toast the breadcrumbs briefly in a dry pan or under a broiler for about 1 minute if you like crisping.
