How to Make Homemade Green Bean Casserole
Step 1: Prepare the Shallots
Start by frying those shallots! Heat vegetable oil in a skillet over medium heat. Add the sliced shallots and fry until they turn golden brown and crispy, about 5-7 minutes. This step adds a crunchy topping that contrasts beautifully with the creamy casserole below.
Step 2: Cook the Green Beans
While your shallots are frying, bring a pot of salted water to a boil. Blanch the trimmed green beans for about 3-4 minutes until they are bright green but still crisp. This process keeps them vibrant while ensuring they don’t become mushy in the casserole.
Step 3: Make the Mushroom Sauce
In another pan, melt butter over medium heat. Add sliced mushrooms and sauté until they’re golden brown, about 5 minutes. Then add garlic and cook for an additional minute. Stir in flour and cook for another minute before slowly whisking in chicken broth. The sauce should thicken nicely—this is where all that creamy goodness comes from!
Step 4: Combine Everything
Once your mushroom sauce has thickened, add in lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes (if using), nutmeg, salt, pepper, cream, and half of your parmesan cheese. Mix well until everything is combined.
Step 5: Assemble and Bake
In a baking dish, combine blanched green beans with the creamy mushroom sauce. Top with crispy fried shallots and sprinkle remaining parmesan cheese on top. Bake in a preheated oven at 350°F for about 25 minutes until bubbly and golden brown.
And there you have it! Your Homemade Green Bean Casserole is ready to shine on your dining table! Enjoy every delicious bite!
