How to Make Homemade Green Bean Casserole
Step 1: Prepare the Crispy Shallots
Start by heating the vegetable oil in a skillet over medium heat. Once hot, carefully add the sliced shallots. Fry them until they turn golden brown and crispy, about 5-7 minutes. This step adds an irresistible crunch to your casserole! Once done, transfer them to paper towels to drain excess oil.
Step 2: Cook the Green Beans
Bring a large pot of salted water to boil. Add your trimmed fresh green beans and cook them until they are bright green but still crisp, about 3-4 minutes. Blanching helps retain their vibrant color and crunch. Drain them well and set aside.
Step 3: Make the Creamy Mushroom Sauce
In the same skillet used for shallots, melt unsalted butter over medium heat. Sauté sliced baby bella mushrooms until they’re golden brown—this brings out their earthy flavor! Add minced garlic and cook until fragrant. Then sprinkle in flour, stirring for about a minute before pouring in chicken broth while continuously whisking to avoid lumps.
Step 4: Combine Everything
Once your sauce has thickened nicely, stir in lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes, nutmeg, salt, and pepper. Finally, add heavy cream and half of your grated parmesan cheese. Mix well until everything is combined.
Step 5: Assemble and Bake
In a greased baking dish, combine the blanched green beans with the creamy mushroom sauce. Top with remaining parmesan cheese and those crispy fried shallots we made earlier. Bake at 350°F (175°C) for about 20-25 minutes until bubbly and golden on top.
And there you have it—a delightful Homemade Green Bean Casserole that’s sure to warm hearts around your table! Enjoy every bite!
