Step-by-Step Cooking Instructions

Now, let’s dive into how to make the Big Montana Casserole. Follow these steps, and you’ll have a flavorful, comforting dish ready in no time!
- Preheat your oven to 375°F (190°C).
- Lightly grease a 9x13-inch baking dish to prevent sticking.
- Cook the ground beef in a large skillet over medium heat.
- Break it up with a spoon and cook until browned, about 8-10 minutes. Season with salt, pepper, and Worcestershire sauce. Once cooked, drain excess fat and set aside.
- Sauté the onions, garlic, and carrots in butter for 4-5 minutes.
- Add the diced onions and carrots to the skillet with the butter and cook until softened. Add the minced garlic in the last minute of cooking to avoid burning.
- Prepare the potatoes by slicing them thinly.
- Use a mandolin slicer or a sharp knife to ensure even, thin slices. This will ensure they cook through and absorb all the flavors in the casserole.
- Make the creamy mixture by combining the cream of mushroom soup, sour cream, and beef broth in a bowl.
- Stir until smooth and well combined. This mixture will act as the creamy sauce for the casserole.
- Layer the ingredients in your prepared baking dish.
- Start by spreading a thin layer of the creamy sauce at the bottom of the dish. Then, layer half of the potato slices evenly. Add half of the ground beef mixture on top, followed by half of the sautéed vegetables, peas (or corn), and shredded cheese. Repeat the layers once more, ending with a final layer of cheese on top.
- Cover the dish with foil and bake in the preheated oven for 40-45 minutes.
- Covering the dish ensures that the potatoes cook through without drying out. After 40 minutes, remove the foil and bake for an additional 10-15 minutes, or until the top is golden and bubbly.
- Let the casserole rest for about 5-10 minutes before serving.
- This helps the layers to set and makes it easier to slice and serve.
How to Cook Big Montana Casserole: A Step-by-Step Guide
To make it even easier to follow, here’s a simplified guide for making the Big Montana Casserole:
- Preheat oven to 375°F (190°C).
- Brown the ground beef and sauté onions, garlic, and carrots.
- Slice potatoes thinly and prepare the creamy sauce.
- Layer: Start with sauce, followed by potatoes, beef, veggies, and cheese.
- Bake covered for 40-45 minutes, then uncover and bake for another 10-15 minutes.
- Let it rest before serving.
Common Mistakes to Avoid
Even with an easy recipe like this, there are a few common mistakes to avoid to ensure your casserole turns out perfectly:
- Undercooking the Potatoes: Make sure your potato slices are thin enough to cook through in the oven. If they’re too thick, they may stay undercooked.
- Not Draining the Ground Beef: Be sure to drain any excess fat from the beef to avoid a greasy casserole.
- Overcrowding the Dish: Don’t pack the ingredients too tightly, as this can affect even cooking. Layer everything evenly to ensure each part gets cooked properly.
Serving and Presentation Tips
Here are some great ways to serve and present your Big Montana Casserole:
- Garnish with Fresh Herbs: A sprinkle of fresh parsley or thyme on top adds a fresh burst of flavor and color.
- Serve with a Side Salad: Balance the richness of the casserole with a light, crisp side salad.
- Rustic Serving Style: Serve the casserole family-style, straight from the baking dish, for a cozy, homestyle meal.
How to Serve Big Montana Casserole
The Big Montana Casserole is a complete meal on its own, but you can serve it with a few sides to round out your dinner:
- Garlic Bread: Serve a warm, buttery slice of garlic bread to mop up the creamy sauce.

- Roasted Vegetables: Add some roasted vegetables like Brussels sprouts or green beans on the side for extra nutrients.
