Whether you’re hosting a special occasion or simply want to enjoy a delicious meal without the last-minute hassle, this guide will provide you with everything you need to know about creating the perfect make-ahead potato casserole.

Ingredients

• Russet potatoes (peeled and thinly sliced)
• Onion (chopped)
• Garlic (minced)
• Butter
• All-purpose flour
• Milk
• Chicken broth
• Cheddar cheese (shredded)
• Monterey Jack cheese (shredded)
• Salt
• Black pepper
• Dried thyme
• Dried rosemary

Step-by-Step Instructions

1. Prepare the Potatoes: Peel and thinly slice the potatoes. Place them in a large bowl of cold water to prevent browning.
2. Sauté the Onion and Garlic: In a large skillet over medium heat, melt the butter. Add the onion and cook until softened. Stir in the garlic and cook for 1 minute more.
3. Make the Roux: Whisk the flour into the butter-onion mixture. Cook for 1 minute, or until the roux is golden brown.
4. Add Liquids: Gradually whisk in the milk and chicken broth until smooth. Bring the mixture to a boil, then reduce the heat and simmer for 5 minutes, or until thickened.
5. Season the Sauce: Add the salt, black pepper, thyme, and rosemary to the sauce. Taste and adjust seasonings as needed.
6. Assemble the Casserole: Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking dish. Drain the potatoes and layer them evenly in the bottom of the dish. Pour the sauce over the potatoes and spread it evenly.
7. Top with Cheese: Sprinkle the cheddar and Monterey Jack cheese over the casserole.
8. Bake: Cover the casserole with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the cheese is melted and bubbly.
9. Serve: Let the casserole rest for 10 minutes before serving.

Make Ahead Instructions

• Assemble the Casserole: Follow steps 1-7 as directed.
• Refrigerate: Cover the assembled casserole tightly with plastic wrap and refrigerate for up to 24 hours.
• Bake: When ready to serve, remove the casserole from the refrigerator and let it come to room temperature for 30 minutes. Preheat the oven to 350°F (175°C). Cover the casserole with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the cheese is melted and bubbly.

Variations

• Add Vegetables: Sautéed mushrooms, bell peppers, or broccoli can be added to the casserole for extra flavor and nutrition.
• Use Different Cheeses: Experiment with different types of cheese, such as Gruyère, Parmesan, or mozzarella, to create unique flavor combinations.
• Add Herbs: Fresh herbs, such as parsley, basil, or chives, can be added to the casserole for extra aroma and flavor.
• Make a Creamy Casserole: Add 1 cup of sour cream or heavy cream to the sauce for a richer and more decadent casserole.

Tips for Success

• Use Russet Potatoes: Russet potatoes have a higher starch content than other types of potatoes, which helps to thicken the sauce.
• Slice the Potatoes Thinly: Thinly sliced potatoes will cook more evenly and absorb the sauce better.
• Don’t Overcook the Sauce: The sauce should be thickened but not too thick. If it becomes too thick, add a little more milk or broth.
• Cover the Casserole: Covering the casserole with aluminum foil prevents the potatoes from drying out during baking.
• Let the Casserole Rest: Letting the casserole rest before serving allows the flavors to meld and the potatoes to absorb the sauce.
