Ingredients List for Big Montana Casserole
To make this crowd-pleasing casserole, you’ll need the following ingredients:
- 1 ½ pounds ground beef (lean or ground chuck)
- 1 medium onion, chopped (for flavor and texture)
- 2 cloves garlic, minced (for extra depth of flavor)
- 1 cup frozen corn (or any other frozen veggies like peas, carrots, or mixed vegetables)
- 1 can cream of mushroom soup (10.5 oz; for the creamy base)
- ½ cup beef broth (to enhance the beefy flavor)
- 1 teaspoon Worcestershire sauce (for added umami)
- 4 cups mashed potatoes (use leftover mashed potatoes or make fresh)
- 1 ½ cups shredded cheddar cheese (for that gooey, cheesy top)
- Salt and pepper (to taste)
- 1 tablespoon olive oil (for sautéing)
- ½ teaspoon smoked paprika (optional, for a smoky flavor)
- ½ teaspoon dried thyme (optional, for a herby touch)
Substitutions and Variations
The beauty of the Big Montana Casserole is that it’s highly customizable, allowing you to adapt the ingredients based on what you have on hand or dietary preferences. Here are some substitution ideas:
- Ground Beef: You can swap the ground beef for ground turkey, chicken, or pork for a lighter option. For a vegetarian version, use crumbled plant-based meat or cooked lentils.
- Mashed Potatoes: Instead of mashed potatoes, you can use sweet potatoes for a different flavor. If you're pressed for time, you can use instant mashed potatoes.
- Vegetables: Feel free to add any vegetables you love! While corn is a classic, you can use green beans, peas, or even sautéed mushrooms.
- Cream Soup: If you prefer, you can swap cream of mushroom for cream of chicken or cream of celery soup.
- Cheese: While cheddar is the traditional choice, you can try using pepper jack for a spicy kick, or Swiss cheese for a milder flavor.
- Dairy-Free Option: If you’re avoiding dairy, use plant-based mashed potatoes, dairy-free cheese, and a non-dairy cream soup.
Step-by-Step Cooking Instructions

Follow these simple steps to make your Big Montana Casserole:
- Preheat the Oven: Set your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish with cooking spray or butter.
- Cook the Ground Beef: In a large skillet, heat the olive oil over medium heat. Add the chopped onion and minced garlic and sauté until soft, about 3-4 minutes. Then, add the ground beef and cook until browned, breaking it up with a spoon as it cooks. Drain any excess fat.
- Season the Beef: Stir in the Worcestershire sauce, salt, pepper, smoked paprika, and thyme. Add the frozen corn (or other vegetables), cream of mushroom soup, and beef broth. Stir to combine and let the mixture simmer for 5 minutes, allowing the flavors to meld.
- Prepare the Mashed Potatoes: While the beef mixture simmers, prepare your mashed potatoes if you haven’t already. You’ll need about 4 cups. You can use leftovers, make fresh from boiled potatoes, or use instant mashed potatoes for convenience. Season with salt and pepper to taste.
- Assemble the Casserole: Spread the beef and vegetable mixture evenly in the prepared casserole dish. Then, gently spread the mashed potatoes over the beef layer, using a spatula to smooth it out.
- Top with Cheese: Sprinkle the shredded cheddar cheese generously over the top of the mashed potato layer.
- Bake: Bake the casserole in the preheated oven for 20-25 minutes, or until the cheese is melted, golden, and bubbly, and the casserole is heated through.
- Garnish and Serve: Remove the casserole from the oven and let it rest for 5 minutes before serving. Garnish with fresh herbs like parsley or chives, if desired, for added color.
How to Cook Big Montana Casserole: A Step-by-Step Guide
- Step 1: Brown the Ground Beef: Start by cooking the ground beef with onions and garlic in a skillet, then add seasoning and vegetables.
- Step 2: Prepare the Potatoes: While the beef mixture simmers, either make fresh mashed potatoes or use leftovers. Instant mashed potatoes work in a pinch.
- Step 3: Layer the Casserole: Spread the beef mixture into a greased baking dish, then top with a thick layer of mashed potatoes.
- Step 4: Add Cheese: Sprinkle cheddar cheese on top for a gooey, golden finish.
- Step 5: Bake and Serve: Bake the casserole at 375°F until the cheese is melted and golden, then serve hot.
Common Mistakes to Avoid
- Not Draining the Beef: If you don’t drain the excess fat after browning the ground beef, the casserole can become greasy.
- Undercooking the Vegetables: Be sure the frozen vegetables are fully cooked through while the beef mixture simmers to avoid biting into cold or undercooked veggies.
- Overbaking: Keep an eye on the casserole as it bakes. Overbaking can lead to dry potatoes and tough cheese. The goal is to just melt the cheese and heat the casserole through.
Serving and Presentation Tips
The Big Montana Casserole is a hearty meal on its own, but it pairs well with a few simple sides. Consider the following serving suggestions and presentation ideas:
- Side Dishes: Serve with a crisp green salad or roasted vegetables for a balanced meal. Rolls or crusty bread make excellent sides for sopping up any extra sauce.
- Condiments: Offer sour cream or gravy on the side for extra richness. Hot sauce or ketchup can also be served for those who like to spice things up.
- Beverage Pairing: A cold beer or glass of red wine complements the savory flavors of the casserole.
