How to Make Homemade Green Bean Casserole
Step 1: Prepare the Crispy Shallots
Start by heating the vegetable oil in a large skillet over medium-high heat. Add the sliced shallots and season with Creole seasoning. Fry them until they turn golden brown and crispy, which usually takes about 5-7 minutes. Remember to keep an eye on them; they can go from perfect to burnt quickly!
Step 2: Cook the Green Beans
In another pot, bring salted water to a boil and blanch the trimmed green beans for about 3-4 minutes until they are bright green but still crisp. This step locks in their color and keeps them crunchy. After blanching, quickly transfer them to an ice bath to stop the cooking process.
Step 3: Make the Mushroom Sauce
In your skillet from earlier, melt the butter over medium heat. Sauté the mushrooms until they’re soft and golden—about 5 minutes. Then add minced garlic and cook for another minute until fragrant. Sprinkle in the flour while stirring constantly; this will help thicken your sauce!
Step 4: Combine Everything
Gradually pour in the chicken broth while stirring continuously. Add lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes, nutmeg, salt, and pepper. Bring this mixture to a gentle simmer until it thickens slightly—this will take about 5 minutes.
Step 5: Assemble and Bake
Preheat your oven to 350°F (175°C). In a large mixing bowl, combine the blanched green beans with your creamy mushroom sauce. Gently fold in half of the grated parmesan cheese before transferring everything into a baking dish. Top with crispy shallots and sprinkle remaining parmesan on top.
Step 6: Enjoy!
Bake in your preheated oven for about 25 minutes or until bubbly and golden on top. Let it rest for a few minutes before serving—this will help set everything together nicely!
Now that you know how easy it is to whip up this delicious Homemade Green Bean Casserole, I can’t wait for you to try it! Your family will be raving about it long after they’ve cleared their plates!
Pro Tips for Making Homemade Green Bean Casserole
