Instructions

Prepare the Potato and Cauliflower Layer: In a large pot, bring salted water to a boil over medium-high heat. Add the diced potatoes and cook for approximately 10 minutes. Then, add the chopped cauliflower to the pot and continue cooking for another 5 minutes, or until the vegetables are tender when pierced with a fork.
Drain and Mash: Remove the pot from the heat and carefully drain the water. Using a potato masher or even just a fork, roughly mash the potatoes and cauliflower. I recommend leaving it a bit chunky for a more rustic texture.
Season and Set Aside: Add the milk, butter, salt, and pepper to the mashed potato and cauliflower mixture. Stir well to combine and set aside.
Cook the Bacon: In a medium saute pan, add the chopped bacon and saute over medium heat until crisp.
Drain the Bacon: Remove the cooked bacon from the pan and place it on a plate lined with paper towels to drain the excess grease.
Sauté the Vegetables: Leave approximately 1 teaspoon of bacon drippings in the pan (drain off any excess – you don’t want the casserole to be oily). Add the diced onion and red pepper to the pan and saute until tender.
Add Scallions and Season: Once the onion and red pepper are cooked, add the diced scallions to the pan. Season with salt and pepper to taste. Remove the pan from the heat and set aside. Drain any excess grease if necessary.
Prepare the Cheese and Crumb Mixture: In a small bowl, combine the melted butter, Italian seasoned breadcrumbs, and shredded Swiss cheese. Mix well to ensure the breadcrumbs are evenly coated with the melted butter and cheese.
Assemble the Casserole: Preheat the oven to 375°F (190°C). Lightly spray a casserole dish with non-stick cooking spray.
Layer the Ingredients: Begin layering the ingredients in the casserole dish. First, spread half of the potato and cauliflower mixture evenly over the bottom of the dish. Next, add half of the bacon, pepper, and onion mixture on top of the potato and cauliflower layer. Finally, sprinkle half of the cheese and breadcrumb mixture over the bacon and vegetable layer.
Repeat the Layers: Repeat the layering process: spread the remaining potato and cauliflower mixture, followed by the remaining bacon, pepper, and onion mixture. Top with the remaining cheese and breadcrumb mixture.
Bake the Casserole: Place the casserole dish in the preheated oven and bake for 30 minutes, or until the top is golden brown and bubbly. The casserole should be heated through and the cheese should be melted and slightly browned.
Cool Slightly and Serve: Remove the casserole from the oven and let it cool for a few minutes before serving. This will allow the casserole to set slightly, making it easier to cut and serve.

Expert Tips & Tricks

Don’t Overcook the Vegetables: Be careful not to overcook the potatoes and cauliflower, as they will become too mushy. They should be tender but still hold their shape slightly.
Crisp Bacon is Key: Make sure the bacon is cooked until crispy. This will add a nice textural contrast to the creamy casserole.
Cheese Variations: Feel free to experiment with different types of cheese. Gruyere, cheddar, or a blend of cheeses would also work well in this casserole.
Make Ahead: The casserole can be assembled ahead of time and stored in the refrigerator for up to 24 hours before baking. Just add a few extra minutes to the baking time if baking from cold.
Browning: If the top of the casserole is browning too quickly, cover it loosely with aluminum foil for the last 10-15 minutes of baking.
