How to Make Homemade Green Bean Casserole
Step 1: Prepare the Fried Shallots
Start by frying those shallots! In a saucepan, heat the vegetable oil over medium heat. Once hot, add the sliced shallots and cook until they turn golden brown. This adds an incredible crunch and sweetness to your casserole. Remember to keep an eye on them – they can go from perfectly fried to burnt in no time!
Step 2: Cook the Green Beans
While your shallots are frying, bring a large pot of salted water to a boil. Add the trimmed green beans and blanch them for about 5 minutes until bright green but still crisp. Drain and set aside. Blanching helps retain their vibrant color and crunchiness in the final dish.
Step 3: Make the Mushroom Sauce
In a skillet, melt the unsalted butter over medium heat. Add sliced baby bella mushrooms and garlic; sauté until tender. Stirring frequently enhances their flavors. Sprinkle in flour to help thicken your sauce. Gradually whisk in chicken broth while cooking until smooth. Add lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes (if using), nutmeg, salt, pepper, heavy cream, and half of the parmesan cheese.
Step 4: Combine Everything
In a large baking dish, combine blanched green beans with your creamy mushroom sauce. Mix well so every green bean gets coated in that luscious sauce. Top with remaining parmesan cheese.
Step 5: Bake and Serve
Preheat your oven to 350°F (175°C) and bake your casserole for about 25 minutes until bubbly and golden on top. Finally, sprinkle those crispy fried shallots over the top just before serving for that delightful crunch!
And there you have it—a Homemade Green Bean Casserole that’s sure to impress at any gathering! Enjoy every delicious bite!
