How to Make Green Bean Casserole
-
Preheat the oven to 400°F. Lightly grease a 9×13-inch baking dish to ensure nothing sticks, making cleanup a breeze later on.
-
Blanch the green beans in a large pot of salted boiling water for 4 minutes. This quick cook will keep them vibrant and tender. Immediately plunge them into a bowl of ice water to stop the cooking process, then drain and dry.
-
Sauté the mushrooms! In a large skillet over medium heat, heat the olive oil and add the sliced mushrooms. Cook for 8 to 10 minutes until they’re soft and fragrant.
-
Combine flavors by stirring in the tamari, garlic, and thyme. Sprinkle the flour over the mixture and stir well to create a roux.
-
Whisk in the milk and Dijon mustard. Let this simmer for 15 to 20 minutes, whisking often, until thickened to a creamy perfection.
-
Add the finishing touches by stirring in Parmesan cheese and black pepper to give your sauce that delightful flavor boost.
-
Layer the casserole by spreading ⅓ of the rich sauce at the bottom of your prepared baking dish. Evenly distribute the drained green beans on top, then pour over the remaining sauce.

Sprinkle the crispy onions generously over the top. Cover with foil and bake for 10 minutes. Remove the foil and bake uncovered for an additional 10 minutes until golden brown.
-
Garnish with extra Parmesan if desired. Serve hot and enjoy the symphony of flavors!
Optional: Try adding a sprinkle of crispy bacon for an extra crunchy twist!

How to Store and Freeze Green Bean Casserole
Fridge: Store leftover green bean casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350°F until warmed through.
Freezer: If you want to prepare ahead, freeze your baked green bean casserole, tightly wrapped in plastic wrap and aluminum foil, for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: For the best results, reheat baked casserole in the oven rather than the microwave to maintain its creamy texture and crispy topping. Cover loosely with foil while reheating to prevent the onions from burning.
Serving Suggestion: Before serving your reheated green bean casserole, consider sprinkling with extra Parmesan cheese for an additional touch of flavor!
Expert Tips for the Best Green Bean Casserole
-
Perfectly Blanched Beans: Make sure to immediately plunge your blanched green beans into ice water. This stops the cooking and retains their vibrant color and crispness, preventing them from becoming mushy.
-
Flavorful Mushrooms: Don’t rush the sautéing process! Allow the mushrooms to cook until they’re truly soft and caramelized, which adds depth to your green bean casserole.
-
Thick Sauce: If your sauce is too thin, let it simmer longer without the lid. Make sure to whisk frequently to avoid lumps. The right thickness will coat your green beans beautifully.
-
Avoid Overbaking: When baking, keep an eye on the crispy onions. If they start to brown too quickly, re-cover the casserole to prevent burning while the inside heats up properly.
-
Homemade Crispy Onions: For an extra touch, try making your own crispy baked onions. They add a personal and delicious touch to your green bean casserole!
