Ingredients:
- 4 medium potatoes, thinly sliced
- 1 cup frozen peas, thawed
- 1 small onion, finely chopped
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 1 1/2 cups milk
- 1 cup shredded cheddar cheese
- 1/4 cup grated Parmesan cheese
- Salt and pepper to taste
- 1/2 teaspoon garlic powder
- 1/2 teaspoon dried thyme (optional)
- 1/4 cup breadcrumbs (optional, for topping)
Instructions:
- Preheat the oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.
- Cook the onion: In a medium saucepan, melt the butter over medium heat. Add the chopped onion and cook until soft and translucent, about 5 minutes.
- Make the sauce: Stir in the flour and cook for 1-2 minutes to eliminate the raw flour taste. Gradually whisk in the milk, continuing to stir until the sauce thickens, about 3-5 minutes. Add the cheddar cheese, garlic powder, thyme (if using), salt, and pepper. Stir until the cheese is melted and the sauce is smooth.
- Assemble the dish: Arrange half of the sliced potatoes in the prepared baking dish. Sprinkle with half of the peas, then pour half of the cheese sauce over the top. Repeat the layers with the remaining potatoes, peas, and cheese sauce.
- Top with Parmesan and breadcrumbs: Sprinkle the grated Parmesan cheese and breadcrumbs (if using) evenly over the top of the casserole.
- Bake: Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the top is golden and bubbly.
- Serve: Allow the dish to cool for a few minutes before serving.
