How to Make Homemade Green Bean Casserole
Step 1: Prepare the Shallots
Start by frying those shallots! Heat the vegetable oil in a skillet over medium heat. Once hot, add the sliced shallots and sprinkle them with Creole Cajun seasoning. Fry until they are golden brown and crispy. This step not only adds texture but also infuses that wonderful flavor throughout your casserole.
Step 2: Cook the Green Beans
While your shallots are crisping up, bring a pot of salted water to boil. Add in those fresh green beans and blanch them for about 5 minutes until they’re bright green and just tender. Shocking them in ice water afterward helps maintain that beautiful color and keeps them crisp!
Step 3: Make the Creamy Mushroom Sauce
In another pan, melt unsalted butter over medium heat. Add sliced mushrooms and sauté until they release their moisture and turn golden brown. Then stir in garlic, followed by flour to create a roux. Gradually whisk in chicken broth while simmering until thickened. Adding lemon juice, Dijon mustard, Worcestershire sauce, thyme, spices, cream, and half of your parmesan turns this into a creamy delight.
Step 4: Combine Everything
In a large bowl, combine the blanched green beans with your luscious mushroom sauce. Mix well so every bean gets coated! Transfer this mixture into a baking dish.
Step 5: Top it Off
Sprinkle the remaining parmesan over your casserole before adding those crispy fried shallots on top. This creates a wonderful contrast between creamy and crunchy textures.
Step 6: Bake
Pop your casserole into a preheated oven at 350°F (175°C) for about 25 minutes or until bubbly and golden on top. The aroma alone will have everyone gathering around!
