How to Make a Quick Potato, Broccoli, and Ham Casserole with Hollandaise

This quick potato broccoli ham casserole layers tender parboiled potatoes, crisp-tender broccoli florets, and savory diced ham in a baking dish. Smothered in creamy hollandaise sauce and topped with shredded cheese, it bakes at 350°F (180°C) for 15 to 20 minutes until bubbling and golden brown.
Why Hollandaise Elevates the Classic Potato Casserole
Traditional weeknight casseroles often rely on heavy cream, flour roux, or canned condensed soups for their moisture. Replacing standard cream sauces with rich hollandaise sauce introduces a buttery, slightly tangy profile that cuts through the starchiness of potatoes and highlights the fresh flavor of broccoli.
Parboiling the potatoes and broccoli beforehand ensures that the vegetables reach optimal tenderness while keeping overall oven time under 20 minutes. Combined with savory cooked ham and a melted cheese topping, this dish creates an ideal balance of comfort, convenience, and rich flavor.

Ingredients and Pantry Essentials
Casserole Base Ingredients
- Potatoes: 600 grams (peeled and cut into bite-sized cubes).
- Broccoli: 1 head fresh broccoli (cut into small florets).
- Cooked Ham: 150 grams (sliced into strips or bite-sized cubes).
Sauce and Topping Ingredients
- Hollandaise Sauce: 1 cup (store-bought or homemade).
- Shredded Cheese: 100 grams (Gouda, Cheddar, or Mozzarella work best).
- Salt & Pepper: To taste for vegetable boiling water.
Step-by-Step Cooking Instructions
1.Prep and Parboil the Vegetables:Parboil for optimal texture.
Peel 600 grams of potatoes and cut them into uniform cubes. Boil in salted water for 8 to 10 minutes until slightly tender. In a separate pot of salted boiling water, cook the broccoli florets for 3 to 4 minutes until crisp-tender. Drain both thoroughly.
2.Assemble the Casserole Dish:Layer evenly for full coverage.
Preheat your oven to 350°F (180°C) convection. Spread the drained potato cubes evenly across the bottom of a greased baking dish. Layer the cooked broccoli florets over the potatoes, then scatter 150 grams of ham strips evenly across the top.
3.Add Sauce and Cheese:Rich coating and golden crust.
Pour 1 cup of hollandaise sauce generously over the layered vegetables and ham, covering the dish evenly. Sprinkle 100 grams of shredded cheese over the top layer.
4.Bake to Golden Perfection:Bake until bubbly.
Bake in the preheated oven for 15 to 20 minutes. The casserole is ready when the sauce is bubbling around the edges and the cheese forms a golden-brown crust on top. Remove and let cool for 5 minutes before serving.

Frequently Asked Questions
Can I use frozen broccoli instead of fresh?
Yes, frozen broccoli florets work well. Thaw and drain them completely before layering to prevent extra moisture from watering down the hollandaise sauce.
What are the best potatoes to use for casseroles?
Yukon Gold or yellow potatoes hold their shape well after parboiling and baking without becoming excessively mushy.
Can I prepare this casserole in advance?
You can assemble the boiled potatoes, broccoli, ham, and sauce in the baking dish up to 24 hours in advance. Cover and refrigerate, then add the cheese and add 5 minutes to the baking time.
Can I substitute the ham with another protein?
Diced cooked chicken breast, turkey bacon, or smoked tofu work as great alternatives to cooked ham in this recipe.
