How to Make Homemade Green Bean Casserole
Step 1: Prepare the Fried Shallots
Start by frying those shallots! Heat the vegetable oil in a skillet over medium heat. Once hot, add the sliced shallots. Fry them until they become golden brown and crispy. This step is crucial as these crunchy bits will be sprinkled on top of your casserole, adding texture and flavor that everyone will love.
Step 2: Blanch the Green Beans
While your shallots are frying, bring a large pot of salted water to boil. Add your trimmed green beans and blanch them for about 3-4 minutes until they’re bright green and slightly tender but still crisp. This helps keep their vibrant color and crunch in the final dish!
Step 3: Make the Creamy Mushroom Sauce
In another large skillet, melt the butter over medium heat. Add sliced mushrooms and cook until they’re browned and their moisture has evaporated. Then stir in garlic, followed by flour. Cooking these together forms a roux that thickens your sauce beautifully. Gradually whisk in chicken broth until smooth. Finally, add lemon juice, dijon mustard, Worcestershire sauce, thyme, red pepper flakes if using, nutmeg, salt, black pepper, heavy cream (or half-and-half), and half of your parmesan cheese.
Step 4: Combine Everything Together
In a large mixing bowl or directly in your skillet (if it’s big enough), combine your blanched green beans with the creamy mushroom sauce. Mix well so every bean is coated in that luscious sauce!
Step 5: Bake Your Casserole
Transfer everything into a greased baking dish. Top with remaining parmesan cheese and those crispy fried shallots you made earlier. Bake at 350°F (175°C) for about 25-30 minutes until bubbly and golden brown on top.
And there you have it—a beautiful Homemade Green Bean Casserole ready to impress your family or guests! Enjoy every bite!
