Prep and Cook Time

• Preparation: 20 minutes
• Cooking: 35 minutes
• Total Time: 55 minutes

Yield

• Serves 6-8 people generously

Difficulty Level

• Medium – friendly for home cooks with some experience

Ingredients

• 1 ½ pounds fresh green beans, trimmed and halved
• 2 tablespoons unsalted butter
• 8 ounces cremini mushrooms, finely chopped
• 1 small onion, finely diced
• 2 cloves garlic, minced
• 2 tablespoons all-purpose flour
• 1 cup whole milk, warmed
• 1 cup low-sodium chicken broth
• ½ cup grated sharp cheddar cheese
• ½ cup French fried onions (plus extra for garnish)
• Salt and freshly ground black pepper, to taste
• 1 teaspoon fresh thyme leaves
• 1 tablespoon olive oil

Instructions

1. Blanch the Green Beans: Bring a large pot of salted water to a boil. Add the green beans and blanch for 2-3 minutes until they turn bright green and just tender but remain crisp. Immediately transfer them to an ice bath to halt cooking and preserve color. Drain and set aside.
2. Prepare the Mushroom Sauce: In a large skillet, melt butter with olive oil over medium heat. Add finely chopped onions and sauté until translucent, about 4 minutes. Stir in minced garlic and cook for an additional minute.
3. Cook Mushrooms: Toss in the mushrooms and sauté until golden and their moisture evaporates, about 7-8 minutes. Season with salt, pepper, and thyme to infuse fragrant layers.
4. Make the Roux: Sprinkle flour evenly over the mushroom mixture and stir continuously for 2 minutes to cook out the raw taste, thickening the base of the sauce.
5. Add Liquids: Gradually whisk in warm milk and chicken broth. Continue stirring until the sauce thickens smoothly and coats the back of a spoon, about 5-7 minutes.
6. Combine with Green Beans: Remove from heat and gently fold in the blanched green beans, half of the French fried onions, and the grated cheddar cheese for a creamy, silky texture.
7. Bake to Perfection: Preheat your oven to 350°F (175°C). Transfer the mixture into a buttered casserole dish, spreading evenly. Top with remaining fried onions. Bake uncovered for 20-25 minutes until bubbling and golden on top.
8. Rest and Serve: Let rest for 5 minutes before serving. This allows the flavors to meld and the casserole to slightly set, ensuring each scoop holds its character.

Tips for Success

• Freshness Matters: Selecting crisp, bright green beans is essential for a vibrant dish. Choose beans that snap easily when bent and have no blemishes.
• For a Creamier Sauce: Substitute whole milk with half-and-half or add a splash of heavy cream for richness without overpowering the fresh flavors.
• Make-Ahead Magic: Prepare the mushroom sauce and blanched beans up to a day ahead; assemble and bake just before serving to keep the topping crisp.
• Go Gluten-Free: Use a gluten-free flour blend for the roux to accommodate dietary preferences without losing the sauce’s luxurious texture.
• Boost Umami Depth: Add a splash of soy sauce or Worcestershire sauce to the mushroom sauce for an even deeper savory punch that complements the veggies.

Serving Suggestions

This refreshing twist on a classic casserole pairs beautifully with roasted turkey or grilled chicken for an impressive holiday or family dinner centerpiece. Serve with a crisp green salad dressed lightly with lemon and olive oil to complement the creamy richness. Garnish with freshly chopped parsley or thyme sprigs for a burst of color and herbal aroma that brightens every bite.
