How to Make Homemade Green Bean Casserole

Heat Oil: Begin by heating the vegetable oil in a pan over medium-high heat. Fry the shallots until they’re golden brown and crispy, which should take about 4-5 minutes. Once done, remove and drain them on paper towels.
Sauté Vegetables: In another pan, melt the unsalted butter over medium heat. Add the sliced baby bella mushrooms and minced garlic, sautéing until the mushrooms are soft and the garlic is fragrant, approximately 3-4 minutes.
Add Flour: Sprinkle the all-purpose flour over the sautéed mushrooms and stir to combine. Cook this mixture for 1-2 minutes, allowing the flour to soak up the flavors.
Whisk in Broth: Gradually whisk in the chicken broth, followed by the lemon juice, Dijon mustard, Worcestershire sauce, dried thyme, red pepper flakes, ground nutmeg, kosher salt, and freshly ground black pepper. Continue cooking until the mixture thickens, about 3-5 minutes.
Incorporate Green Beans: Stir in the fresh green beans and heavy whipping cream. Cook until the green beans are tender yet still vibrant, which should take about 8-10 minutes.
Transfer to Dish: Carefully transfer the creamy green bean mixture to a baking dish. Spread it out evenly and top with half of the freshly grated Parmesan, saving the rest for later.
Bake: Preheat your oven to 350°F (175°C). Bake the casserole for 25-30 minutes, or until it’s bubbly and the top is golden brown.
Garnish and Serve: Once out of the oven, serve the dish topped with the crispy fried shallots for an added crunch. Enjoy every bite!

Optional: For extra flavor, add a sprinkle of fresh herbs on top just before serving.

Tips for the Best Homemade Green Bean Casserole

Crispy Shallots Tip: Fry shallots in hot oil until golden brown and keep them on paper towels to absorb excess oil for that perfect crunch.

Thicken Wisely: Add flour slowly to the sautéed mushrooms to avoid lumps. This ensures a smooth, creamy sauce for your casserole.

Taste as You Go: Keep seasoning in check! Taste the mixture after adding chicken broth and adjustments to salt, pepper, and Creole seasoning is key for delicious homemade green bean casserole.

Green Beans Care: Do not overcook the green beans during the final cooking step; they should be tender but still have a vibrant color and slight crunch.

Layer It Right: When transferring to the baking dish, spread the mixture evenly and remember to reserve half the Parmesan for the topping, achieving the perfect cheesy finish!
