How to Make Homemade Green Bean Casserole
Step 1: Prepare the Shallots
Start by frying those shallots until they’re golden brown. Heating them slowly in vegetable oil will draw out their natural sweetness and give you that perfect crispy topping. It’s worth it!
Step 2: Blanch the Green Beans
While your shallots are frying away, bring a pot of water to boil. Blanch your green beans for about 5 minutes until they’re bright green but still crisp. This step keeps them vibrant and crunchy when baked!
Step 3: Make the Creamy Sauce
In a large skillet, melt butter over medium heat. Sauté sliced mushrooms until they are tender. Then add garlic and flour, stirring continuously until combined. Gradually whisk in chicken broth while cooking until thickened—it’s the heart of our delicious casserole.
Step 4: Combine Everything
Add lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes, nutmeg, salt, pepper, cream, and half of your parmesan cheese to the mushroom mixture. Stir well before adding the blanched green beans.
Step 5: Bake
Transfer everything into a baking dish and top with crispy fried shallots and remaining parmesan cheese. Bake at 350°F for about 25 minutes until bubbly and golden on top.
And there you have it—a beautiful Homemade Green Bean Casserole that will surely become a cherished recipe in your home! Enjoy every bite!
