Pierogi Casserole Delight: A Comfort Food Classic

Ingredients

Main Components

• 12 frozen potato‑and‑cheese pierogi (about 3 cups)
• 6 slices thick‑cut bacon, chopped
• 1 cup shredded sharp cheddar cheese
• ½ cup grated Parmesan cheese

Custard & Sauce

• 4 large eggs
• 1 ½ cups whole milk
• ½ cup sour cream
• 2 Tbsp melted butter

Seasonings & Garnish

• 1 small onion, finely diced
• 1 red bell pepper, diced
• ¼ tsp smoked paprika
• Salt and freshly ground black pepper to taste
• 2 Tbsp fresh chives, chopped (for garnish)

Instructions

Building the Base

1. Sauté aromatics. Add the diced onion and red bell pepper to the bacon‑fat‑laden skillet. Cook, stirring occasionally, for 3‑4 minutes until softened and lightly caramelized. This step infuses the fat with sweet, savory notes that will permeate the entire casserole.
2. Combine cheese. Sprinkle the shredded cheddar and grated Parmesan into the skillet, stirring until the cheeses melt into a cohesive, glossy mixture. The melted cheese forms the base of the sauce, ensuring every pierogi bite is coated in richness.
3. Mix custard. In a separate bowl, whisk together the eggs, whole milk, sour cream, melted butter, smoked paprika, salt, and pepper until smooth. The custard will set the casserole, creating a tender, custardy interior.
4. Assemble layers. Lightly grease a 9‑x‑13‑inch baking dish. Spread half of the pierogi evenly across the bottom, then pour half of the cheese‑and‑bacon mixture over them. Sprinkle half of the crispy bacon pieces, then repeat with the remaining pierogi, custard, and bacon. Finish by sprinkling the remaining cheddar on top for a golden crust.
5. Bake to perfection. Place the dish in the preheated oven and bake for 25‑30 minutes, or until the custard is set, the top is bubbling, and the cheese has turned a deep golden brown. A quick visual cue: the edges should be slightly crisp while the center jiggles gently when the dish is nudged.
