How to Make Homemade Green Bean Casserole
Step 1: Prepare the Shallots
Start by frying the shallots until they are golden brown and crispy. This step adds an irresistible crunch on top of your casserole. The process may take about 5-7 minutes, but trust me—it’s worth every second!
Step 2: Cook the Green Beans
Blanch your fresh green beans in boiling water for 3-4 minutes until they are bright green but still crisp. This keeps them vibrant and prevents them from getting mushy in your casserole.
Step 3: Make the Creamy Sauce
In a saucepan, melt unsalted butter over medium heat, then sauté sliced mushrooms until they are soft. This brings out their rich umami flavor! Next, add garlic, flour, and gradually whisk in chicken broth along with lemon juice, Dijon mustard, Worcestershire sauce, thyme, nutmeg, salt, and pepper. Stir until thickened; this will be your luscious sauce.
Step 4: Combine Everything
In a large mixing bowl, combine blanched green beans with your creamy mushroom sauce. Make sure every bean gets coated well! Then fold in half of your grated parmesan cheese for that extra cheesy goodness.
Step 5: Assemble and Bake
Transfer the mixture into a greased baking dish. Top it off with remaining parmesan cheese and those crispy fried shallots we made earlier. Bake at 350°F (175°C) for about 25 minutes until bubbly and golden brown on top!
And there you have it—a Homemade Green Bean Casserole that’s bound to become a staple at your table! Enjoy every bite!
