Ingredients:

For the Potato Layer:

2 lbs Russet potatoes, peeled and cubed
1/4 cup milk (any kind works, I prefer whole milk for richness)
4 tablespoons butter, melted
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon garlic powder

For the Broccoli Layer:

1 large head of broccoli, cut into florets (about 4 cups)
1 tablespoon olive oil
1/4 teaspoon salt
1/8 teaspoon black pepper

For the Cheese Sauce:

4 tablespoons butter
4 tablespoons all-purpose flour
3 cups milk (again, whole milk is great, but 2% works too)
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon garlic powder
1/4 teaspoon onion powder
1/4 teaspoon ground nutmeg (optional, but adds a lovely warmth)
4 cups shredded cheddar cheese (sharp cheddar is my favorite!)

For the Topping (Optional):

1/2 cup breadcrumbs (panko or regular)
2 tablespoons melted butter
1/4 cup shredded Parmesan cheese

Preparing the Potato Layer:

Okay, let’s start with the foundation of our casserole the potatoes! This is a super simple mashed potato layer, but it adds so much comfort.

Boil the Potatoes: Place the peeled and cubed potatoes in a large pot. Cover them with cold water and add a pinch of salt. Bring the water to a boil over high heat, then reduce the heat to medium and let the potatoes simmer until they are fork-tender. This usually takes about 15-20 minutes. You should be able to easily pierce them with a fork.
Drain the Potatoes: Once the potatoes are cooked, carefully drain them in a colander. Make sure to get rid of all the water!
Mash the Potatoes: Return the drained potatoes to the pot. Add the milk, melted butter, salt, pepper, and garlic powder. Use a potato masher (or an electric mixer for extra smooth potatoes) to mash everything together until you reach your desired consistency. I like mine a little bit chunky, but you can make them as smooth as you like.
Taste and Adjust: Give the mashed potatoes a taste and adjust the seasoning as needed. You might want to add a little more salt, pepper, or garlic powder depending on your preference.

Preparing the Broccoli Layer:

Next up, we’re going to quickly prepare the broccoli. Roasting it brings out the best flavor, in my opinion, but you can also steam it if you prefer.

Preheat the Oven: Preheat your oven to 400°F (200°C).
Prepare the Broccoli: In a large bowl, toss the broccoli florets with olive oil, salt, and pepper. Make sure the broccoli is evenly coated.
Roast the Broccoli: Spread the broccoli florets in a single layer on a baking sheet. Roast for 15-20 minutes, or until the broccoli is tender-crisp and slightly browned. Keep an eye on it, as ovens can vary! You want it cooked but not mushy.

Making the Cheese Sauce:

Now for the star of the show the creamy, cheesy sauce! This is a classic cheese sauce, and it’s what really brings this casserole together.

Melt the Butter: In a medium saucepan, melt the butter over medium heat.
Add the Flour: Whisk in the flour and cook for 1-2 minutes, stirring constantly. This creates a roux, which will thicken the sauce. Be careful not to burn the flour!
Whisk in the Milk: Gradually whisk in the milk, about 1/2 cup at a time, making sure to whisk out any lumps before adding more. Continue whisking until all the milk is incorporated and the sauce is smooth.
Simmer the Sauce: Bring the sauce to a simmer, stirring constantly. Reduce the heat to low and continue to simmer for 5-7 minutes, or until the sauce has thickened slightly. It should be thick enough to coat the back of a spoon.
Add the Seasonings: Stir in the salt, pepper, garlic powder, onion powder, and nutmeg (if using).
Melt the Cheese: Remove the saucepan from the heat and stir in the shredded cheddar cheese until it is completely melted and the sauce is smooth and creamy. This is important! Make sure all the cheese is melted for the best texture.
Taste and Adjust: Taste the cheese sauce and adjust the seasoning as needed. You might want to add a little more salt, pepper, or cheese depending on your preference.

Assembling the Casserole:

Time to put everything together! This is the fun part.

Preheat the Oven: Preheat your oven to 350°F (175°C).
Grease the Baking Dish: Grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the casserole from sticking.
Layer the Potatoes: Spread the mashed potatoes evenly in the bottom of the prepared baking dish.
Layer the Broccoli: Spread the roasted broccoli florets evenly over the mashed potatoes.
Pour the Cheese Sauce: Pour the cheese sauce evenly over the broccoli. Make sure everything is nicely covered.
Prepare the Topping (Optional): In a small bowl, combine the breadcrumbs, melted butter, and Parmesan cheese. Sprinkle the mixture evenly over the cheese sauce. This adds a nice crunchy texture.

Baking the Casserole:

Almost there! Just a little bit of baking time and we’ll be ready to enjoy this delicious casserole.

Bake the Casserole: Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the topping (if using) is golden brown.
Let it Rest: Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the cheese sauce to set up a bit and makes it easier to serve.
