Instructions

1. Blanch the Green Beans

  • Bring 2 quarts of water and 2 tablespoons of salt to a boil.

  • Prepare an ice bath in a large bowl.

  • Add green beans to boiling water; cook for 1½–2 minutes until tender-crisp.

  • Transfer beans to the ice bath to halt cooking.

  • Once cooled, drain, pat dry, and cut into 2-inch pieces. Set aside.

2. Prepare the Herbed Croutons

  • In a bowl, combine torn bread pieces with chopped thyme and 1 tablespoon olive oil.

  • Gently toss to coat evenly. Set aside.

3. Cook Bacon and Shallots

  • In a cast iron Oval Roaster, off heat, mix bacon, shallots, and 1 teaspoon olive oil.

  • Place over medium-low heat; cook, stirring often, until bacon fat renders and both bacon and shallots are browned and crisp (8–10 minutes).

  • Use a slotted spoon to transfer to a paper towel-lined plate. Reserve drippings in the roaster.

4. Sauté Leeks and Mushrooms

  • Add butter to the reserved drippings; melt over medium heat until foamy.

  • Add leeks and mushrooms; season with salt.

  • Cook, stirring, until leeks are soft and mushrooms release their juices (about 5 minutes).

5. Combine and Simmer

  • Pour in turkey or chicken stock; simmer for 2 minutes to slightly reduce.

  • Fold in the blanched green beans; stir until heated through.

  • Season with additional salt and pepper to taste.

6. Assemble and Broil

  • Preheat broiler.

  • Crumble goat cheese over the vegetable mixture.

  • Top with prepared herbed croutons.

  • Place the roaster under the broiler; cook until cheese melts and croutons are golden brown and crispy (about 90 seconds). Watch closely to prevent burning.

7. Garnish and Serve

  • Remove from broiler; sprinkle reserved crispy bacon and shallots over the top.

  • Serve immediately.

Frequently Asked Questions

Can I use regular green beans instead of French green beans?
Yes, regular green beans can be used. Just ensure they are trimmed and cooked to a tender-crisp texture.

What can I substitute for goat cheese?
Feta cheese or a soft cream cheese can be used as alternatives, though they will alter the flavor profile slightly.

Is there a vegetarian version of this casserole?
Absolutely. Omit the bacon and use vegetable stock instead of turkey or chicken stock.

Can I prepare this dish in advance?
You can prepare the components ahead of time and assemble just before broiling to maintain the crispness of the croutons.

What other mushrooms can I use?
Button mushrooms or portobello mushrooms can be used if shiitake and cremini are unavailable.

How do I store leftovers?
Store in an airtight container in the refrigerator for up to 3 days. Reheat in the oven to retain crispness.
