How to Make Homemade Green Bean Casserole
Step 1: Prepare the Shallots
Start by heating the vegetable oil in a deep skillet over medium heat. Once hot, add the sliced shallots carefully. Fry them until they’re golden brown and crispy. This step is crucial because those crispy shallots will add a delightful crunch on top of your casserole!
Step 2: Cook the Green Beans
While the shallots fry, bring a pot of salted water to boil. Add the trimmed green beans and cook them for about 5-7 minutes until they are tender yet still crisp. This helps maintain their vibrant color and fresh texture.
Step 3: Make the Mushroom Sauce
In another pan, melt the butter over medium heat. Add the sliced mushrooms and garlic, sautéing until they are soft and fragrant. Then sprinkle in the flour and stir well. This creates a roux that will help thicken your creamy sauce!
Step 4: Combine Ingredients
Slowly whisk in the chicken broth while stirring constantly. Then add lemon juice, Dijon mustard, Worcestershire sauce, dried thyme, red pepper flakes, nutmeg, salt, and pepper. Once everything is combined and bubbling gently, stir in the heavy cream and half of your parmesan cheese.
Step 5: Assemble the Casserole
In a large baking dish, combine the cooked green beans with your creamy mushroom sauce. Mix well so every bean gets coated! Top with remaining parmesan cheese and those crispy shallots we made earlier.
Step 6: Bake
Preheat your oven to 350°F (175°C) and bake for about 25 minutes until bubbly and golden on top. The aroma wafting through your kitchen will be absolutely irresistible!
And there you have it—a comforting Homemade Green Bean Casserole that’s sure to become one of your favorites too! Enjoy every delicious bite!
