How to Make Homemade Green Bean Casserole
Step 1: Prepare the Shallots
Start by heating the vegetable oil in a skillet over medium heat. Once hot, add your sliced shallots. Fry them until they turn golden brown and crisp. This step is essential because those crispy shallots will provide a delightful texture contrast in your casserole!
Step 2: Blanch the Green Beans
While your shallots are frying, bring a pot of salted water to boil. Add your trimmed green beans and blanch them for about 5 minutes until they are bright green but still crisp. This helps maintain their vibrant color and keeps them from getting mushy in the oven.
Step 3: Create the Mushroom Sauce
In a separate saucepan, melt butter over medium heat. Add sliced mushrooms and garlic, sautéing until they’re tender. Then sprinkle in flour and stir well to create a roux. Gradually whisk in chicken broth along with lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes (if using), nutmeg, salt, and pepper. Stir until smooth; let it thicken for about 5 minutes.
Step 4: Combine Everything
Once your mushroom sauce is ready, add blanched green beans into the mixture along with half of the grated parmesan cheese. Gently fold everything together to ensure those beautiful green beans are coated in that rich sauce.
Step 5: Bake Your Casserole
Transfer everything into a greased baking dish. Top with remaining parmesan cheese and those crispy fried shallots we made earlier. Bake at 350°F (175°C) for about 25 minutes or until bubbly and golden on top.
And there you have it! Your Homemade Green Bean Casserole is ready to enjoy! Serve it warm as a perfect side dish at your next meal—it’s sure to be loved by everyone around the table!
