Ingredients

Scale

Meat and Vegetables

  • 6 strips bacon
  • 1/2 yellow onion (finely diced)
  • 1 1/2 cups chopped button mushrooms
  • 3 cloves garlic (minced)
  • 4 (14.5-ounce) cans cut green beans (drained)

Dairy

  • 1/4 cup milk
  • 1 cup shredded Monterey Jack cheese

Canned Goods

  • 2 (10.5-ounce) cans cream of mushroom soup

Other

  • Salt and pepper, to taste
  • 1 1/2 cups French fried onions

Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 350°F (175°C) and lightly spray a 9×13-inch baking dish with nonstick cooking spray to prevent sticking.
  2. Cook Bacon and Onions: In a large skillet over medium-low heat, cook the bacon strips until crisp. Remove and drain on paper towels, then crumble. Drain all but about 2 tablespoons of the bacon grease from the skillet and return the pan to medium heat. Add the finely diced onion and cook, stirring occasionally, for about 5 minutes until the onion is translucent.
  3. Sauté Mushrooms and Garlic: Add the chopped button mushrooms to the skillet and cook, stirring occasionally, for 5 minutes until golden brown. Add minced garlic and cook for an additional 1 minute until fragrant.
  4. Combine Soup and Dairy: Stir in the undiluted cream of mushroom soup. Return the crumbled bacon to the skillet and mix well. Add milk and shredded Monterey Jack cheese; stir until the cheese is fully melted and incorporated. Season with salt and pepper to taste.
  5. Add Green Beans: Fold the drained green beans gently into the mixture until well combined.
  6. Assemble and Bake: Pour the combined mixture into the prepared baking dish and spread evenly. Top with French fried onions. Bake uncovered for 30 minutes or until the casserole is hot and bubbly and the topping is nicely golden.

Notes

  • Draining the bacon grease to just 2 tablespoons enhances flavor without excess fat.
  • Using undiluted cream of mushroom soup ensures the casserole has a creamy, rich texture.
  • For extra crispiness, you can add additional French fried onions during the last 5 minutes of baking.
  • Feel free to substitute Monterey Jack cheese with cheddar for a sharper flavor.
  • This casserole can be prepared ahead of time and refrigerated before baking; just increase baking time slightly.
