Instructions
- Prepare the Soup Mixture: In a large bowl, stir together the condensed cream of mushroom soup, milk, ground black pepper, and salt until smooth and well combined.
- Sauté the Vegetables: Heat butter and olive oil in a sauté pan over medium heat. Once hot, add the sliced sweet onion and mushrooms. Cook, stirring occasionally, until the vegetables become soft and golden brown. Remove from heat.
- Combine Ingredients: Add the drained green beans, sautéed onions, and mushrooms to the bowl with the soup mixture. Stir until everything is evenly coated.
- Add Cheese: Fold in 1 cup of shredded pepper jack cheese and mix well until evenly incorporated into the casserole mixture.
- Assemble the Casserole: Transfer the mixture to a 3-quart casserole dish, spreading it out evenly and leaving the dish uncovered.
- Bake the Casserole: Bake in a preheated oven at 350°F (175°C) for 25 minutes, or until the bean mixture is hot and bubbling.
- Add Toppings and Finish Baking: Stir the bean mixture gently, then sprinkle the top with crispy fried onions and the remaining 1/4 cup of pepper jack cheese. Return the dish to the oven and bake for an additional 5 minutes, or until the onions are golden brown.
Notes
- For a milder cheese flavor, substitute pepper jack cheese with mild cheddar.
- Drain the green beans well to avoid a watery casserole.
- Use fresh mushrooms and sweet onion for the best flavor.
- This casserole is best served warm immediately after baking.
- Leftovers can be refrigerated in an airtight container for up to 3 days.
