Ingredients
Scale
- 2 (15 oz) cans of cut green beans, drained (or 1 lb fresh/frozen green beans, blanched)
- 1 (10.5 oz) can condensed cream of mushroom soup (or homemade version)
- ¾ cup whole milk
- 1 (2.8 oz) can French fried onions (or homemade fried shallots)
- 2 tbsp butter (for homemade sauce)
- 1 cup button mushrooms, sliced (for homemade sauce)
- 2 cloves garlic, minced (for homemade sauce)
- 2 tbsp all-purpose flour (for thickening homemade sauce)
- 1 cup chicken stock (for homemade sauce)
- ½ cup heavy cream (for homemade sauce)
- 1 tbsp soy sauce (optional for umami boost)
- Salt and pepper to taste
- Fresh thyme or rosemary (optional for garnish)
Instructions
- Prep the Green Beans: If using fresh or frozen, blanch the green beans in boiling salted water for 2-4 minutes, then shock them in an ice bath. Drain and set aside. If using canned beans, simply drain them.
- Make the Mushroom Sauce (if Homemade):
- Melt butter in a skillet over medium heat. Add mushrooms and sauté for 5-7 minutes until golden brown.
- Stir in garlic and cook for 1 more minute.
- Sprinkle in flour and stir constantly to form a roux.
- Slowly pour in chicken stock and cream, whisking until the sauce thickens (about 5 minutes). Season with salt, pepper, and optional soy sauce.
- Combine Ingredients: In a large mixing bowl, combine the green beans, mushroom sauce (or canned soup), milk, and half the fried onions. Season with salt and pepper.
- Bake: Preheat the oven to 350°F. Transfer the mixture to a greased casserole dish and spread evenly. Bake for 25-30 minutes until hot and bubbly.
- Add Crispy Onion Topping: Remove the casserole from the oven and sprinkle the remaining fried onions on top. Bake for an additional 5-10 minutes until the onions are golden brown.
- Serve: Let it cool slightly before serving. Garnish with fresh thyme or rosemary, if desired.
Notes
- Make-Ahead Tip: Assemble the casserole (without the fried onion topping) up to 2 days in advance and store it in the fridge. Add the topping and bake when ready to serve.
- Customization Options: Add bacon, shredded cheese, or switch the soup to cream of chicken for a different flavor.
- Gluten-Free Option: Use gluten-free mushroom soup and gluten-free fried onions or crispy shallots.
