How to Make Homemade Green Bean Casserole
Step 1: Prepare the Crispy Shallots
Start by heating the vegetable oil in a large skillet over medium heat. Once hot, add the sliced shallots. Fry them until they turn golden brown and crispy. This step is key because crispy shallots give that delightful crunch on top of your casserole!
Step 2: Cook the Green Beans
While the shallots are frying, bring a pot of salted water to a boil. Blanch your trimmed green beans in boiling water for about three minutes until they are bright green but still crisp. This helps maintain their vibrant color and crunchiness.
Step 3: Make the Mushroom Sauce
In another skillet, melt butter over medium heat. Add sliced mushrooms and minced garlic; sauté until they’re tender. This step builds flavor! Sprinkle in flour and stir well. Gradually whisk in chicken broth while cooking until thickened. Then add lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes (if using), nutmeg, salt, pepper, cream, and half of your parmesan cheese.
Step 4: Assemble Your Casserole
In a large mixing bowl, combine blanched green beans with your creamy mushroom sauce. Mix well so every bean is coated in that luscious goodness! Transfer everything into a baking dish and top with remaining parmesan cheese and those crispy shallots.
Step 5: Bake
Preheat your oven to 350°F (175°C) and bake your casserole for about 25 minutes until bubbly and golden brown on top. The aroma will fill your kitchen—trust me; it’s irresistible!
Now you’re ready to serve up this delightful Homemade Green Bean Casserole! Enjoy every delicious bite with your loved ones!
