How to Make Homemade Green Bean Casserole
Step 1: Prepare the Shallots
First things first—let’s get those crispy shallots ready! In a pan, heat the vegetable oil over medium-high heat. Once it’s hot, add your thinly sliced shallots. Fry them until they turn golden brown and crispy. This step is key because those crunchy shallots will add delightful texture to your casserole!
Step 2: Cook the Green Beans
While the shallots are frying, bring a large pot of salted water to boil. Add in your trimmed green beans and cook them for about 5-7 minutes until they’re bright green but still crisp. This blanching helps keep them vibrant and tender without becoming mushy.
Step 3: Make the Creamy Mushroom Sauce
In another pan, melt butter over medium heat. Add in sliced baby bella mushrooms and minced garlic. Sauté until they’re soft and fragrant, which enhances their natural umami flavor. Sprinkle flour over them and stir well; this helps thicken our sauce later.
Step 4: Combine Everything
Slowly whisk in chicken broth while stirring continuously to avoid lumps. Then add lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes if you’re using them, nutmeg, salt, and pepper. Finally, pour in heavy cream and half of your parmesan cheese. Mix everything until it’s creamy and smooth—this is where all the magic happens!
Step 5: Assemble the Casserole
In a baking dish, combine your blanched green beans with the creamy mushroom sauce. Give it a gentle stir to coat all those beautiful beans in goodness! Top with remaining parmesan cheese and your crispy shallots.
Step 6: Bake Until Golden
Preheat your oven to 375°F (190°C) if you haven’t already done so. Bake your casserole for about 25 minutes or until bubbly and golden on top. The aroma will fill your kitchen, making it hard to wait!
And there you have it—a delightful Homemade Green Bean Casserole that’s sure to impress! Enjoy every bite with loved ones around you!
