Instructions
Prepare the Potatoes
- Wash the potatoes thoroughly and peel them if desired.Cut the potatoes into evenly sized pieces, approximately 1-inch cubes. Keeping the pieces similar in size helps them cook evenly.Place the potatoes in a large pot and cover them with cold water.Add 1 teaspoon of salt.Bring the water to a boil, then reduce the heat slightly and simmer for approximately 8–12 minutes, or until the potatoes are tender but still firm enough to hold their shape.Do not overcook the potatoes because they will continue cooking in the oven.Drain well and set aside.
Cook the Bacon
- Place the chopped bacon in a large skillet over medium heat.Cook until the bacon becomes crisp and golden, stirring occasionally.Transfer approximately two-thirds of the cooked bacon to a plate lined with paper towels.Leave a small amount of bacon fat in the skillet for cooking the onions.
Caramelize the Onions
- Add the diced onion to the skillet.Cook for approximately 5–7 minutes, stirring occasionally, until the onions become soft and lightly caramelized.Add the minced garlic and cook for another 30–60 seconds.Be careful not to burn the garlic.
Prepare the Dressing
- Reduce the heat to medium-low.Sprinkle the flour over the onion mixture and stir well.Cook for approximately 1 minute.Slowly pour in the chicken broth while whisking to prevent lumps.Add the apple cider vinegar, Dijon mustard, whole-grain mustard, brown sugar, smoked paprika, salt, and black pepper.Stir until the sauce begins to thicken.
Add the Creamy Ingredients
- Remove the skillet from the heat.Allow the mixture to cool slightly for a minute or two.Stir in the sour cream and mayonnaise until smooth.The sauce should be creamy, tangy, savory, and slightly sweet.
Transfer to the Baking Dish
- Preheat the oven to 375°F (190°C).Lightly grease a 9 × 13-inch baking dish.Transfer the potato mixture into the dish and spread it evenly.Sprinkle the optional Swiss cheese or Gruyère over the top.Add the remaining crispy bacon.
Bake the Casserole
- Place the casserole in the preheated oven.Bake uncovered for approximately 25–30 minutes, or until hot and bubbling around the edges.The top should become lightly golden.For an extra-crispy top, place the casserole under the broiler for 1–2 minutes at the end.Watch carefully because the topping can brown quickly.
Garnish and Serve
- Sprinkle the casserole with fresh parsley and sliced green onions.Add a few extra crispy bacon pieces on top.Serve the Hot German Potato Salad Casserole warm.
Notes
- Do not overcook the potatoes: They should be tender but firm because they will cook again in the oven.
- Use waxy potatoes: Yukon Gold and red potatoes hold their shape especially well.
- Cook the bacon until crisp: Crispy bacon provides the best contrast to the soft potatoes.
- Balance the vinegar: Apple cider vinegar provides the characteristic tang, but adjust slightly according to taste.
- Add the sour cream off the heat: This helps prevent the sauce from becoming grainy.
- Do not overmix: Gentle folding keeps the potato pieces intact.
- Cheese is optional: Traditional German potato salad does not require cheese, but it works well in this casserole-style version.
- Serve warm: The flavors and texture are best when the casserole is served hot or warm.
