Green Bean Casserole In A Skillet

Green Bean Casseroles are probably a classic and every cook probably has their favorite recipe stashed away in their repertoire. While some prefer using frozen and canned ingredients quickly tossed together with some green beans, I prefer a clean recipe with fresh ingredients and all made from scratch.

I find that using nice fresh ingredients is vital to achieving the flavors we’re going for today. This casserole is pretty dense, with super rich ingredients so we need some fresh bright flavors to lighten it all up. Try this side dish out for your next big holiday get together, believe me you won’t regret it.

My favorite thing about this incredible green bean casserole is the crispy fried onions, and the super rich base – and well I guess all of it. All in all, this casserole is my family’s favorite. A true comfort food that’s a must on your Thanksgiving table.

Ingredient Notes

Crispy onions

• Onions – Medium mild flavored onion like white or yellow onions.
• Dry ingredients – All purpose flour, salt, and panko bread crumbs.

Green beans

• Veggies – Fresh trimmed green beans and cremini mushrooms. Regular white mushrooms work as well.
• Butter – Unsalted so as to control the sodium content of our dish.
• Garlic – Essential to add flavor to our casserole.
• Flour – All purpose flour to help thicken our sauce.
• Nutmeg – Ground up adding the perfect flavor kick to our dish. There’s nothing like nutmeg in a nice creamy sauce.
• Liquids – Low sodium chicken broth and heavy cream. You can use half and half for a lighter version.
• Bacon – 3 slices of bacon fried up fresh and chopped up. This is an optional ingredients, but we know that bacon makes everything better.

How To Make Green Bean Casserole From Scratch

1. Onions: Add the flour, breadcrumbs and salt to a bowl and mix. Add the onions and toss them in the flour mixture. Spread the onions over the baking sheet and bake for 30 minutes or until crispy and golden brown. Reduce the oven heat to 400 F degrees.
2. Green Beans: Add about a gallon of water and a tsp of salt to a large pot and bring it to a boil. Add the green beans to the pot and blanch for 5 minutes. Remove the beans from the boiling water and plunge them into a large bowl of ice water, to stop the cooking. Drain and set aside.
3. Sauce: Melt the 2 tbsp of butter in a large skillet over medium heat. Add the mushrooms, season with salt and pepper and cook for about 5 minutes, stirring occasionally. Add the minced garlic and nutmeg to the skillet and cook for another minute or 2 until the garlic becomes fragrant. Sprinkle the 2 tbsp of flour over the mushrooms and stir to combine well. Add the chicken broth, stir with a wooden spoon and cook for a minute. Decrease the heat to medium-low and add the heavy cream. Continue cooking for another 6 to 8 minutes until the mixture thickens.
4. Assemble: Turn off the heat and add the green beans, chopped bacon and a quarter of the crispy onion. Stir well then top with remaining crispy onions. Place the skillet in the oven and bake for 15 minutes until bubbly.
