I’ve always wanted to make a Green Bean Casserole from scratch. I can finally say I have… the result? Nothing short of amazingness.

Now, let me be frank – I won’t ever hate on the canned variety of green bean casserole, because that’s what I grew up on and still thoroughly enjoy it. However, THIS my friends is incredible. Homemade is THE way to go. Especially with my beloved onion straws on top… err and throughout (Ya, I may have gone a little heavy handed on the onion straws… but that’s how I roll. hah)

The actual filling on this is super fast and easy. It’s the onion straws that take the most time since you have to do them in batches. Do them the night before and crisp them up on a cookie sheet the day of (I’ve done this before). Or make this a semi-homemade recipe and make the filling yourself, but top it with the canned onion straws (I won’t hate).

Regardless, you should probably make this ASAP (if not for Thanksgiving, dog ear/bookmark it for Christmas)… it’s delicious. Excuse me while I go crawl into an onion straw a coma now…

Happy Thanksgiving week everyone!

What are YOUR plans for celebrating?!

Green Bean Casserole from Scratch

Yield: 8 servings

Prep Time: 10-15 minutes

Cook Time: 1 hour

Total Time: 1 hour 15 minutes


1.25 pounds fresh green breans, rinsed, ends trimmed, and cut in half
2-3 tablespoons salted butter
12 ounces mushrooms, wiped clean and sliced
3/4 teaspoon salt
1/2 teaspoon black pepper
2 large cloves garlic (or 3 small), grated
dash of cayenne
3 tablespoons flour
1 cup low sodium chicken broth
1 cup half and half
1/2 batch of homemade Onion Straws (or 2-3 cups canned onion straws)


Bring a pot of water to a boil (salt the water if you'd like) and blanch the green beans for 5-8 minutes. Strain and set aside.

Preheat oven to 350° F and spray a casserole dish with non-stick cooking spray. Melt the butter in a large cast iron skillet over medium high heat. Add the mushrooms, salt and pepper and saute until mushroom are soft and have released some of their moisture (about 5-8 minutes). Add the garlic and cayenne and saute for another minute (stirring constantly).

Dust the mixture with the flour and stir until combined (about 1 minute). Add the chicken broth and bring to a simmer (2-3 minutes). Add the half and half and simmer until thickened (8-10 minutes). Stir in the green beans and 2 cups of the onion straws.

Pour entire mixture into prepared casserole dish and sprinkle with additional onion straws (as many as your heart desires!). Bake for 20-25 minutes until hot and bubbly.
