Ingredients
Scale
- 3 shallots, thinly sliced into rings
- 1 cup vegetable oil (for frying)
- Kosher salt + pinch of Creole/Cajun seasoning, to taste
- 24 oz fresh green beans, trimmed
- 8 oz baby bella mushrooms, sliced
- 1 shallot, finely chopped
- 4 tbsp unsalted butter
- 1 tbsp garlic, minced or paste
- 1 1/2 cups chicken broth
- 2 tbsp all-purpose flour
- 1/2 cup heavy whipping cream
- 1/2 cup Parmesan, finely grated
- 2 tsp Dijon mustard
- 1 tbsp Worcestershire sauce
- 1 tbsp fresh lemon juice
- 1 tsp dried thyme
- 1/4 tsp ground nutmeg
- 1/2 tsp red pepper flakes
- 1 tsp Creole/Cajun seasoning
- Kosher salt & freshly ground black pepper, to taste
Instructions
- Heat oil to 340°F and fry shallot rings 3–5 minutes until golden brown. Drain on paper towels and season.
- Blanch green beans in salted boiling water for 3–4 minutes, then shock in ice water. Drain well.
- In oven-safe skillet, melt butter. Cook mushrooms and chopped shallot 5–6 minutes. Stir in garlic, thyme, and red pepper flakes for 1 minute.
- Sprinkle flour, cook 1 minute. Slowly whisk in chicken broth. Add mustard, Worcestershire, lemon juice, nutmeg, Cajun seasoning, salt, and pepper. Simmer 3–4 minutes until thickened.
- Stir in cream and half the Parmesan until smooth. Fold in beans. Top with remaining Parmesan and half the crispy shallots.
- Bake at 375°F for 18–22 minutes until bubbly and lightly browned.
- Top with remaining crispy shallots just before serving.
Notes
For lighter version, swap heavy cream for half-and-half. Use baked onions instead of fried for healthier topping. To make vegetarian, use vegetable broth. Assemble ahead (without shallots) up to 2 days in advance.
