Key Ingredients & Substitutions
Potatoes: Use starchy potatoes like Russets or Yukon Golds for the best texture. If you’re short on time, pre-sliced frozen potatoes work too, but they might release extra moisture.
Cheddar Cheese: Sharp cheddar gives a nice tang. You can try medium cheddar for a milder flavor or even a mix of cheeses like Monterey Jack or Gouda. Just remember to use cheese that melts well!
Milk: Whole milk makes the sauce creamy, but you can switch to 2% or even almond milk for a lighter version. If you’re avoiding dairy, look for a plant-based milk that has added protein.
Onion and Garlic: These ingredients add depth to the sauce, but if you’re not a fan of onions, you can skip them. Shallots or leeks can also be great substitutes for a different flavor profile.
Herbs: Dried thyme is standard, but feel free to use fresh herbs like rosemary or parsley for a different taste. Oregano would also be a nice addition if you like a Mediterranean twist.
How Do I Get a Smooth Cheese Sauce?
The key to a velvety cheese sauce is the roux, which is a mixture of butter and flour. Follow these steps to nail it:
- Melt the butter in your saucepan over medium heat, then add the chopped onion if you’re using it.
- Sauté until the onion is soft; then add minced garlic for flavor.
- After the garlic is fragrant, sprinkle in the flour and stir it for about 1-2 minutes. This helps to cook off the raw flour taste.
- Gradually pour in the milk while whisking constantly to avoid lumps. Keep stirring as it heats up.
- When the sauce thickens and bubbles gently, take it off the heat and mix in the cheese until melted into a creamy consistency.
Be sure to whisk well at every step. If it’s too thick, add a splash more milk until you reach your desired consistency!
How to Make Cheesy Scalloped Potatoes Bake
Ingredients You’ll Need:
For the Potato Bake:
- 4 cups thinly sliced potatoes (about 4-5 medium potatoes)
- 2 cups shredded sharp cheddar cheese
- 3 cups whole milk
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 1 small onion, finely chopped (optional)
- 2 cloves garlic, minced
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme or 1 tablespoon fresh thyme leaves
- 1/2 cup grated Parmesan cheese
- Fresh thyme sprigs for garnish (optional)
How Much Time Will You Need?
This delightful dish takes about 15 minutes to prepare. You’ll need an additional 1 hour and 5 minutes to bake—45 minutes covered and another 20-25 minutes uncovered. Altogether, you’re looking at around 1 hour and 20 minutes from start to serving!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 375°F (190°C). While that’s warming up, grab a 9×13 inch baking dish and grease it with butter or spray it with cooking spray to prevent sticking.
2. Make the Cheese Sauce:
In a large saucepan, melt the butter over medium heat. If you’re using it, add the chopped onion and sauté for about 3-4 minutes until it becomes translucent. Next, add the minced garlic and cook for another minute until it’s fragrant.
3. Create the Roux and Sauce:
Now, sprinkle in the flour, stirring constantly for about 1-2 minutes until it’s well combined, forming a roux. Gradually whisk in the milk, making sure to break up any lumps. Keep whisking and cooking until the sauce thickens and begins to bubble gently, which should take about 5-7 minutes.
4. Add Cheese and Seasonings:
Remove the saucepan from heat and stir in 1 1/2 cups of the shredded cheddar cheese until it’s melted and smooth. Sprinkle in the salt, pepper, and thyme to season the cheese sauce.
5. Layer the Potatoes:
Now it’s time to layer! Start by arranging half of the potato slices evenly in the prepared baking dish. Pour half of the cheese sauce over the potatoes, spreading it out evenly.
6. Repeat the Layers:
Next, layer the remaining potato slices on top, followed by the rest of the cheese sauce. Sprinkle the grated Parmesan and the remaining cheddar cheese evenly over the top to get that nice, cheesy crust you love!
7. Bake:
Cover the dish tightly with aluminum foil and bake for 45 minutes. After that time, carefully remove the foil and let it bake for another 20-25 minutes, or until the top is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
8. Cool and Serve:
Once baked, let the scalloped potatoes cool for about 5-10 minutes before serving. This will help the layers set a little more. If you’d like, garnish with fresh thyme sprigs for a lovely presentation. Serve warm and enjoy this creamy, cheesydelight!
Can I Use Different Types of Potatoes?
Absolutely! While Russet or Yukon Gold potatoes are ideal for their creaminess, you can also try red potatoes or even sweet potatoes for a different flavor. Just remember that sweeter varieties may change the dish’s overall taste!
Is It Possible to Make This Recipe Gluten-Free?
Yes, you can easily make this dish gluten-free by substituting the all-purpose flour with a gluten-free flour blend or cornstarch. Just make sure to whisk it well with milk to avoid any lumps.
Can I Prepare Cheesy Scalloped Potatoes in Advance?
Definitely! You can assemble the dish ahead of time and refrigerate it (without baking) for up to 24 hours. When you’re ready to serve, simply pop it in the oven; you may need to extend the baking time slightly if it’s chilled.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in the oven or microwave, stirring occasionally to ensure even heating and keep it creamy.
