Pro Tips for the Perfect Ultimate Green Bean Casserole
- Render, then reserve: Cook bacon low and slow so the fat renders cleanly. Then reserve about 2 tablespoons of drippings to flavor the vegetables.
- Sweat before sear: Soften onions gently first; then raise the heat to brown mushrooms. Consequently, you’ll build deep flavor without watery sauce.
- Thicken smartly: Stir the soup and milk until smooth before adding cheese. Thus, the casserole bakes creamy rather than curdled or greasy.
- Fold, don’t mash: Gently fold in drained green beans. Otherwise, over-mixing can break them and thin the sauce.
- Crisp timing: Add the fried onions right before baking. Finally, bake uncovered so the topping stays shatter-crisp.

Ingredients:
- 6 strips bacon
- ½ yellow onion (finely diced)
- 1 ½ cups chopped button mushrooms
- 3 cloves garlic (minced)
- 2 (10.5-ounce) cans cream of mushroom soup
- ¼ cup milk
- 1 cup shredded Monterey Jack cheese
- Salt and pepper
- 4 (14.5-ounce) cans cut green beans (drained)
- 1 ½ cups French fried onions
Directions:
- Preheat and prep the dish: Preheat the oven to 350°F and lightly spray a 9×13-inch baking dish with nonstick cooking spray. Meanwhile, set out paper towels for draining bacon.
- Crisp the bacon: In a large skillet, cook the bacon over medium-low heat until crisp. Remove to drain on paper towels, then crumble. Drain away all but about 2 tablespoons of the bacon grease, then return the pan to medium heat.
- Build the flavor base: Add the onions and cook, stirring occasionally, about 5 minutes or until translucent. Add the mushrooms and cook, stirring occasionally, for 5 minutes or until the mushrooms are golden brown. Add the garlic and cook for 1 minute, or just until fragrant.
- Stir in the creamy elements: Stir in the undiluted mushroom soup and add the crumbled bacon back. Stir to combine. Stir in the milk and cheese. Stir until the cheese is melted. Add salt and pepper to taste.
- Fold in the beans: Fold in the drained green beans until well combined, keeping the mixture creamy and the beans intact. Taste and adjust seasoning.
- Top and bake: Pour the mixture into the prepared dish. Top with the fried onions. Bake, uncovered, for 30 minutes or until the casserole is hot and bubbly, and the onions are deeply crisp.
