How to Make Homemade Green Bean Casserole
Step 1: Prepare the Shallots
Start by heating the vegetable oil in a medium pan over medium heat. Once hot, add in those thinly sliced shallots. Fry them until they turn golden brown and crispy. This step is vital because these shallots will add a delightful crunch and sweetness to your casserole.
Step 2: Cook the Green Beans
In another pot of boiling salted water, blanch the fresh green beans for about 5 minutes until they’re bright green but still crisp. This ensures they maintain their vibrant color and crunchy texture when baked.
Step 3: Sauté the Mushrooms
In a large skillet, melt the unsalted butter over medium heat. Add the sliced mushrooms along with minced garlic. Sauté until they’re tender and fragrant. This step builds layers of flavor that make your casserole truly irresistible!
Step 4: Make the Creamy Sauce
Sprinkle in the flour over the sautéed mushrooms, stirring well to combine. Gradually whisk in chicken broth, followed by lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes (if using), nutmeg, salt, and pepper. Simmer until thickened—this creamy mixture is what makes your casserole so comforting.
Step 5: Combine Ingredients
In a large bowl, mix together the blanched green beans, creamy mushroom sauce, and half of the grated parmesan cheese. Stir until everything is well coated.
Step 6: Bake Your Casserole
Transfer your mixture into a baking dish and sprinkle with remaining parmesan cheese on top. Bake in a preheated oven at 350°F (175°C) for about 25 minutes until bubbly and golden brown.
Step 7: Top with Crispy Shallots
Once baked, remove from the oven and top generously with those crispy fried shallots you prepared earlier. They add that final touch of crunch that’s simply irresistible!
Now you’re ready to enjoy your delicious Homemade Green Bean Casserole! Serve it warm alongside your favorite dishes—it’s sure to become a family favorite!
