Ingredients
6 large russet potatoes washed and sliced into thick rounds
3 tablespoons butter
2 tablespoons olive oil
2 large onions finely chopped
6 cloves garlic minced
2 pounds ground beef
1 pound smoked sausage sliced into rounds
2 teaspoons salt
1 teaspoon black pepper
1 teaspoon smoked paprika
1 teaspoon chili powder
1 teaspoon dried oregano
1 teaspoon thyme
1 teaspoon crushed red pepper
2 cups mushrooms sliced
2 bell peppers chopped
2 cups corn kernels
2 cups cooked kidney beans
3 tablespoons flour
4 cups milk
2 cups heavy cream
4 cups shredded cheddar cheese
2 cups mozzarella cheese
1 cup parmesan cheese
1 cup sour cream
2 tablespoons mustard
2 tablespoons Worcestershire sauce
1 tablespoon hot sauce
2 cups crushed crackers
1 cup breadcrumbs
2 tablespoons melted butter
Fresh parsley chopped
Green onions sliced
Instructions
Begin by preparing the potatoes. Wash them carefully and slice them into thick rustic rounds. Place the potatoes into a large bowl filled with cold water and allow them to soak for at least thirty minutes. This removes extra starch and helps them become crisp during baking. Drain the potatoes and dry them thoroughly with clean towels.
Heat a large skillet over medium heat and add olive oil together with butter. Add the onions and cook slowly until soft and golden brown. Stir often so they caramelize gently without burning. Add minced garlic and continue cooking for another minute until fragrant.
Add the ground beef to the skillet and break it apart using a wooden spoon. Cook until browned and rich in color. Add smoked sausage slices and continue cooking until slightly crispy around the edges. Season the mixture with salt, black pepper, smoked paprika, chili powder, oregano, thyme, and crushed red pepper. Stir carefully to coat everything evenly.
Add mushrooms and bell peppers into the skillet. Cook slowly until the vegetables soften and release moisture. Add corn and kidney beans and stir until fully combined. Reduce heat to low and allow the mixture to simmer gently while preparing the creamy cheese sauce.
In another large saucepan melt butter over medium heat. Add flour and whisk continuously for several minutes until smooth and lightly golden. Slowly pour in milk while whisking constantly to prevent lumps. Add heavy cream and continue stirring until the sauce thickens into a silky texture.
Add cheddar cheese, mozzarella cheese, and parmesan cheese gradually while stirring. Continue mixing until completely melted and smooth. Stir in sour cream, mustard, Worcestershire sauce, and hot sauce. Taste the sauce and adjust seasoning if needed.
Preheat the oven to 375 degrees Fahrenheit. Grease a very large baking dish generously with butter or oil.
Arrange one layer of potato slices across the bottom of the dish. Spoon some beef and sausage mixture over the potatoes. Pour part of the cheese sauce over the layer. Repeat the process again and again until all ingredients are used, creating several thick layers of potatoes, meat, vegetables, and creamy sauce.
In a small bowl combine crushed crackers, breadcrumbs, and melted butter. Sprinkle this mixture evenly over the top of the casserole. Add extra cheddar cheese if desired.
Cover the dish loosely with foil and bake for one hour. Remove the foil and continue baking for another thirty to forty minutes until the top becomes deeply golden brown and bubbling at the edges. The potatoes should be tender when pierced with a knife.
Allow the casserole to rest for at least fifteen minutes before serving. This helps the layers settle and become easier to cut into large portions.
Top with fresh parsley and sliced green onions before serving.
Michigan Rocks can be served with warm bread, roasted vegetables, pickles, creamy coleslaw, or a cold salad. The leftovers become even richer the next day because the flavors continue blending together overnight.
For an extra smoky version you can add bacon between the layers. For a spicier version add jalapeños and extra chili powder. For a more northern-style comfort variation use smoked whitefish together with the beef and potatoes for a Great Lakes inspired flavor.
Cooking slowly is the secret to this recipe. The long baking time allows the potatoes to absorb the creamy sauce while the cheese forms a rich crust on top. Every bite becomes soft, smoky, creamy, crispy, and deeply comforting.
This giant Michigan Rocks recipe is designed for very large portions and can feed a big family gathering, holiday table, or celebration meal with plenty of leftovers for later enjoyment.
