Loaded Scalloped Potatoes are a comforting, creamy dish featuring tender slices of potatoes baked in a rich cheese sauce with crispy bits of bacon and green onions scattered throughout. It’s a hearty side that feels like a warm hug on a plate, perfect for family dinners or holiday gatherings.
I love making this dish when I want something easy but with that wow factor. The combination of gooey cheese and bacon gives it such a delicious flavor that everyone always asks for seconds. My secret? Adding a bit of garlic powder to the sauce—it gives just the right hint of extra flavor without overpowering the creamy goodness.
Serving Loaded Scalloped Potatoes alongside roasted chicken or a fresh green salad makes for a balanced meal that’s sure to please. I also like to let it cool a little before serving so the sauce thickens just enough to hold every cheesy, bacon piece perfectly on the fork. It’s one of those dishes that’s better the next day, too!
Key Ingredients & Substitutions for Loaded Scalloped Potatoes
Russet Potatoes: These starchy potatoes are perfect as they become soft while baking. If needed, Yukon Golds work too, but they hold their shape more.
Bacon: Adds smoky, salty flavor. You can swap with turkey bacon or smoked sausage for a leaner or different twist.
Sharp Cheddar Cheese: Gives a nice tang and meltiness. Try Colby Jack or Monterey Jack for a milder taste.
Heavy Cream & Milk: The combo creates a rich sauce. Whole milk or half-and-half can be used, but reduce cream a bit to keep it creamy without being too heavy.
Onion & Garlic: They build the base flavor. If fresh garlic isn’t handy, garlic powder works in a pinch.
How Do You Make a Smooth, Thick Cheese Sauce Without Lumps?
Making the cheese sauce is key here. Follow these simple steps to get a creamy sauce:
- Melt butter over medium heat, then cook onions and garlic until soft but not browned.
- Add flour and stir constantly for 1-2 minutes to form the roux — this thickens the sauce and removes the raw flour taste.
- Slowly add cream and milk while whisking. Keep whisking so no lumps form. The sauce will thicken in about 5 minutes.
- Remove from heat, then stir in cheese gradually so it melts smoothly. Season with salt, pepper, and smoked paprika if you like.
Patience and constant whisking help avoid lumps and give you a velvety sauce perfect for coating the potatoes.
Equipment You’ll Need
- 9×13-inch baking dish – I like this size because it holds all the layers without spilling over.
- Saucepan – useful for making the cheese sauce, ensuring everything cooks evenly.
- Sharp knife and cutting board – for peeling and slicing potatoes thinly so they cook evenly.
- Mixing spoon or whisk – helps you stir the sauce smoothly and combine ingredients.
- Aluminum foil – keeps the potatoes moist while baking and prevents over-browning.
Flavor Variations & Add-Ins
- Swap bacon for cooked pancetta or chorizo for a different smoky flavor.
- Add sautéed mushrooms or cooked spinach between layers for more veggies and earthiness.
- Mix in diced jalapeños or hot sauce for a spicy kick.
- Replace smoked paprika with cayenne pepper for extra heat or leave it out for a milder dish.
Loaded Scalloped Potatoes
Ingredients You’ll Need:
- 4 large russet potatoes, peeled and thinly sliced
- 6 slices bacon, cooked and crumbled
- 2 cups shredded sharp cheddar cheese
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 2 cups heavy cream
- 1 cup whole milk
- 3 tbsp unsalted butter
- 3 tbsp all-purpose flour
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp smoked paprika (optional)
- 1/4 cup fresh parsley, chopped (for garnish)
How Much Time Will You Need?
Plan for about 15 minutes of prep time to slice potatoes and prepare the sauce, then around 70-75 minutes for baking. This adds up to nearly 1 hour and 30 minutes from start to finish.
Step-by-Step Instructions:
1. Preparing Your Oven and Dish
Start by preheating your oven to 350°F (175°C). While it heats, grease a large baking dish with butter or non-stick spray to keep the potatoes from sticking.
2. Making the Cheese Sauce
In a saucepan over medium heat, melt the butter. Add the chopped onion and minced garlic, cooking them until soft and fragrant, about 3 to 4 minutes. Stir in the flour and cook for 1 to 2 minutes, stirring constantly to form a roux without burning. Slowly whisk in the heavy cream and milk, whisking continuously until the sauce thickens, about 5 minutes. Remove the sauce from heat and stir in 1 ½ cups of shredded cheddar cheese, salt, pepper, and smoked paprika until the sauce is smooth and creamy.
3. Assembling the Layers
Place half of the sliced potatoes in the bottom of the prepared baking dish. Pour half of the cheesy sauce evenly over the potatoes, then sprinkle half of the crumbled bacon on top. Repeat the layers with the remaining potatoes, sauce, and bacon. Finally, sprinkle the remaining ½ cup of shredded cheddar cheese evenly over the top.
4. Baking and Finishing Touches
Cover the baking dish with aluminum foil and bake for 45 minutes. Then, remove the foil and bake uncovered for an additional 25 to 30 minutes until the potatoes are tender and the top is golden brown and bubbly. Let the dish cool for about 5 minutes, then garnish with fresh chopped parsley before serving. Enjoy your warm, loaded scalloped potatoes!
Can I Use Frozen Potatoes for This Recipe?
It’s best to use fresh potatoes for scalloped potatoes to ensure they cook evenly and don’t release extra moisture. If you must use frozen, thaw completely and pat dry before slicing and layering.
How Should I Store Leftover Scalloped Potatoes?
Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm gently in the oven at 350°F until heated through to maintain the creamy texture.
Can I Make Loaded Scalloped Potatoes Ahead of Time?
Yes! Assemble the dish and cover it tightly with foil, then refrigerate for up to 24 hours before baking. You may need to add an extra 10-15 minutes to the baking time if baking cold.
What Can I Substitute for Heavy Cream?
You can use half-and-half or a mixture of milk and sour cream for a lighter sauce, but the texture won’t be quite as rich and creamy.
