🥕 Ingredients (Fresh + From-Scratch)

• 2 lb fresh green beans, trimmed and halved
• 3 tbsp unsalted butter
• 1 small shallot (or ½ small onion), finely chopped
• 3 cloves garlic, minced
• 8 oz cremini or button mushrooms, finely chopped
• 3 tbsp all-purpose flour
• 1½ cups low-sodium chicken or vegetable broth, warm
• 1½ cups milk (whole or 2%), warm
• ½ tsp dried thyme (or 1 tsp fresh)
• ½ tsp kosher salt (plus more to taste)
• ¼ tsp black or white pepper
• Pinch of nutmeg (optional, cozy lift)
• 2 to 2½ cups crispy fried onions (homemade or store-bought)
• Optional: ½ cup finely grated Parmesan for extra savory depth

Little lift: a tiny pinch of nutmeg warms the creamy base without stealing the show.

🍳 How to Make It

1. Blanch the beans.
   Big pot of salted water to a boil.
   Add green beans; cook 4–5 minutes until bright and crisp-tender.
   Drain and plunge into ice water; drain again and pat dry.
2. Build the flavor.
   In a wide skillet or Dutch oven, melt butter over medium.
   Add shallot and a pinch of salt; cook until soft and glossy.
   Stir in garlic for 30 seconds.
3. Sauté the mushrooms.
   Add mushrooms; cook until they release liquid and it cooks off.
   The pan should smell deep and savory.
4. Make the creamy base.
   Sprinkle flour over the pan and stir 60–90 seconds.
   Slowly whisk in warm broth, then warm milk, stirring until smooth.
   Simmer 3–5 minutes until the sauce coats a spoon.
5. Season to perfection.
   Stir in thyme, salt, pepper, and nutmeg if using.
   Taste and adjust.
   (Add Parmesan here if you’d like a gently savory finish.)
6. Combine.
   Fold in green beans until every piece is glossy and coated.
   If the sauce feels thick, loosen with a splash of warm milk; if thin, simmer 1–2 minutes more.
7. Top and bake.
   Heat oven to 375°F (190°C).
   Transfer to a 9×13 (or similar) baking dish.
   Crown generously with crispy onions.
   Bake 15–18 minutes until bubbling at the edges and the top is deep golden.
8. Rest and serve.
   Let it sit 5 minutes so layers settle, then scoop big and enjoy.
