How to Make Homemade Green Bean Casserole
Step 1: Prepare the Crispy Shallots
Start by heating the vegetable oil in a deep skillet over medium heat. Add the sliced shallots and fry them until they turn golden brown. This process is essential as it adds an amazing crunch and sweetness to your casserole. Once cooked, drain them on paper towels and season lightly with Creole seasoning.
Step 2: Blanch the Green Beans
In another pot, bring salted water to a boil. Add your trimmed green beans and blanch them for about 3-4 minutes until they’re bright green but still crisp. This step keeps them vibrant and ensures they don’t become mushy when baked.
Step 3: Make the Creamy Mushroom Sauce
In a large saucepan over medium heat, melt the butter. Add the sliced mushrooms and sauté until they release their moisture and start to brown—this enhances their flavor. Then stir in garlic and cook for another minute before adding flour to create a roux. Gradually whisk in chicken broth while ensuring there are no lumps.
Step 4: Add Flavorful Ingredients
Once your sauce thickens slightly, mix in lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes (if using), nutmeg, salt, and pepper. Finally, stir in the heavy cream and half of the grated parmesan until well combined.
Step 5: Combine Everything Together
In a large mixing bowl, combine your blanched green beans with the creamy mushroom sauce. Stir gently until all beans are well coated. Transfer this mixture into a baking dish and sprinkle the remaining parmesan on top.
Step 6: Bake to Perfection
Preheat your oven to 350°F (175°C) and bake your casserole for about 25 minutes until bubbly and golden brown. In the last few minutes of baking, add those crispy shallots on top so they get warm but remain crunchy.
And there you have it! A comforting Homemade Green Bean Casserole that is sure to impress at any gathering while bringing smiles around the table. Enjoy every bite!
Pro Tips for Making Homemade Green Bean Casserole

Choose Fresh Green Beans: Opt for fresh green beans instead of frozen ones. They add a delightful crunch and vibrant color, enhancing the overall texture of your casserole.
