How to Make Homemade Green Bean Casserole
Step 1: Prepare the Crispy Shallots
Start by heating your vegetable oil in a skillet over medium-high heat. Once hot, carefully add your sliced shallots. Fry them until they are golden brown and crispy—this step is key because those shallots will add a delightful crunch to your casserole.
Step 2: Cook the Green Beans
While your shallots are crisping up, bring a large pot of salted water to a boil. Add in your fresh green beans and cook them until just tender but still bright green. This ensures they maintain their crunch when baked later.
Step 3: Make the Creamy Mushroom Sauce
In another pan, melt your butter over medium heat. Sauté the sliced mushrooms until they’re browned and fragrant. Add the minced garlic next; cooking until it’s aromatic enhances the flavor of your sauce.
Step 4: Combine Everything
Now, stir in flour to create a roux, followed by chicken broth and let it simmer until thickened. Don’t forget to add your lemon juice, Dijon mustard, Worcestershire sauce, thyme, red pepper flakes (if using), nutmeg, salt, and pepper. Finally, mix in that lovely cream!
Step 5: Assemble and Bake
In a baking dish, combine the cooked green beans with your creamy mushroom sauce. Top generously with crispy shallots and half of your grated parmesan. Bake until bubbly—your kitchen will smell heavenly!
And there you have it! Your Homemade Green Bean Casserole is ready to be enjoyed! It’s rich in flavors and textures while being easy enough for any night of the week. Enjoy!
Pro Tips for Making Homemade Green Bean Casserole
Creating the perfect Homemade Green Bean Casserole is all about the details, and these pro tips will help you elevate your dish to new heights!
-
Use Fresh Green Beans: Fresh beans not only enhance the flavor but also maintain a delightful crunch that adds texture to your casserole. Look for vibrant green beans that snap easily when bent.
-
Make Your Own Fried Shallots: While store-bought options are convenient, homemade fried shallots have superior flavor and crispiness. Plus, they’re easy to make and can be adjusted with seasoning to suit your taste.
-
Don’t Skip the Lemon Juice: A splash of fresh lemon juice brightens the flavors in your creamy sauce, balancing richness while adding a subtle zing that will keep everyone coming back for seconds.

Experiment with Cheese Varieties: While parmesan is traditional, feel free to mix in other cheeses like Gruyère or cheddar for a unique twist. This can add a depth of flavor that makes your casserole stand out.
-
Let It Rest Before Serving: Allowing your casserole to sit for about 10 minutes after baking helps it set up nicely. This ensures clean slices and easier serving, making it look as good as it tastes!
