What Makes This Recipe The Best?

I used to be a big fan of traditional green bean casseroles until I read the ingredients on the back of a can of cream of mushroom soup. Some manufacturers include monosodium glutamate, a controversial additive.

I'm not a canned soup hater, and I still use the chicken flavor in several dishes as long as it's free of MSG. But, after making this homemade casserole without condensed soup, I'm a believer. Y''s so fresh, tasty, and creamy...I'll never go back to the old way again.

Why You'll Love It

This made-from-scratch recipe is truly the best Green Bean Casserole I've ever eaten. And, you'll love the addition of soy sauce, an ingredient that gives the mushroom sauce its extraordinary flavor.

It's also nice to free up your oven during the holidays which is why I love making this recipe in my cast iron skillet. (ad) If you don't have a skillet, feel free to bake it in a regular 9 x 13 inch dish.

How to Make Green Bean Casserole

There are 6 easy steps to follow when making this homemade recipe.

  1. Sauté mushrooms and onions in butter until tender.
  2. Add soy sauce, dried parsley and garlic. Continue to sauté.
  3. Stir in flour mixed with water, followed by milk and heavy cream.
  4. Add green beans and pepper. Stir gently.
  5. Top beans with parmesan cheese.
  6. Sprinkle casserole with fried onions and bake at 350 degrees for 20 minutes until onions are golden brown.

What are Haricots Verts?

Haricots Verts is the french name for fine green beans. They're normally thinner and more tender than regular green beans, which allows a quicker cook time. The tenderness also makes them an excellent choice for casseroles and other dishes.

I use frozen Haricots Verts in this recipe, mainly so the beans don't need to be blanched. If you decide to use fresh green beans, be sure to trim and blanch them in advance or they'll be tough and need more time to cook.

Can I Use Canned Green Beans?

Grocery stores carry canned french green beans, but I don't recommend using them. I promise you'll be more pleased with the outcome if you use fresh or frozen french green beans. They cook in a snap, and the homemade taste is hard to beat!

Serving Tips

Skillet Green Bean Casserole is best when served hot out of the oven while the fried onions are still crispy. Try not to cover this dish with a lid or foil because the steam will cause the onions to lose their crispiness.
