Ingredients You’ll Need 🥔🧄🧈

Here’s what makes this dish unforgettable:

5 lbs Russet potatoes, sliced ⅛” thick 🥔
Russet potatoes are ideal for scalloped potatoes — they’re starchy enough to make the sauce thick and creamy without becoming mushy.
2 cups onions, chopped small 🧅
Sweet or yellow onions work best here for flavor depth.
6 cloves garlic, minced 🧄
Garlic brings a delicious aroma and warmth to the dish.
¼ cup butter (½ stick) 🧈
¼ cup flour
Helps create a smooth, velvety roux for the cheese sauce.
1½ cups vegetable broth
Adds moisture and balances the richness of the cream.
1½ cups heavy cream 🥛
Gives the sauce its decadent texture.
1 tablespoon salt
2 teaspoons pepper
2 teaspoons Slap Ya Mama® seasoning 🌶️
Adds a Southern-style kick and bold flavor. You can substitute with Cajun or Creole seasoning.
8 oz sour cream
3 cups cheddar cheese, grated, divided 🧀
Sharp cheddar gives the dish its signature flavor and melty goodness.
1 cup pepper jack cheese, grated 🌶️🧀
Adds just the right touch of spice.
1 cup freshly grated Parmesan cheese 🧀
Brings a salty, nutty finish to the top layer.

Step-by-Step Directions 👩‍🍳

1. Prepare the baking dish and potatoes

Preheat your oven to 400°F (200°C) and spray a 14 x 11½ x 2¼-inch baking dish with non-stick spray.

Peel and thinly slice your potatoes — a mandoline slicer works wonders for achieving even ⅛-inch slices. Place them in a large bowl of cold water to keep them from browning while you prepare the sauce.

2. Make the creamy garlic sauce

In a large skillet, melt the butter over low heat. Add the onions and garlic, and sauté gently for about 4–5 minutes, until softened and fragrant.

Sprinkle in the flour and stir constantly for a couple of minutes to create a roux. Once it turns lightly golden, slowly whisk in the vegetable broth to avoid lumps.

Add the heavy cream, salt, pepper, and Slap Ya Mama® seasoning. Stir until the sauce thickens slightly and becomes smooth and creamy — remove from the heat just before it starts to boil.

Now, stir in 2 cups of cheddar cheese until fully melted into the sauce. The result should be a rich, velvety cheese sauce that coats a spoon beautifully. 😋

3. Layer the potatoes

Drain the sliced potatoes and pat them dry.

Layer ⅓ of the potatoes on the bottom of your prepared dish. Spread ⅓ of the sour cream over the potatoes, then pour ⅓ of the cheese sauce evenly on top. Sprinkle with ⅓ of the Parmesan, ⅓ of the pepper jack, and ⅓ of the remaining cheddar cheese.

Repeat this process two more times, finishing with a generous layer of cheddar on top for that golden crust.

4. Bake to perfection

Cover the dish with foil and bake for 1½ to 2 hours, or until the potatoes are tender when pierced with a fork.

About 15–20 minutes before the end, remove the foil to let the cheese bubble and brown beautifully on top. That’s when the magic happens — you’ll see golden edges and smell the irresistible aroma of baked cheese and garlic filling your kitchen.

5. Rest and serve

Once baked, remove from the oven and let it rest for 15 minutes before serving. This allows the layers to settle, making it easier to cut neat portions.

Serve warm alongside your Christmas ham, turkey, or roast beef, and watch it disappear from the table. 🎄🍴

Tips for the Best Scalloped Potatoes 🔥

Use freshly grated cheese: Pre-shredded cheese can contain anti-caking agents that affect melting.
Don’t skip the resting time: It helps the sauce thicken and hold together.
Customize the flavor: Add chopped fresh herbs like thyme, parsley, or chives for a festive touch.
Make ahead: Assemble the dish the night before, cover, and refrigerate. Bake on Christmas Day for stress-free cooking.
Reheat beautifully: Cover leftovers with foil and warm in the oven at 350°F until bubbly again.

Serving Suggestions 🍗🥦🍷

This dish pairs wonderfully with:

Roast turkey or chicken – the creaminess balances savory meats.
Glazed ham – the salty-sweet glaze complements the cheesy richness.
Steamed broccoli or green beans – for a fresh pop of color and texture.
Cranberry sauce or a crisp green salad – adds brightness to the meal.

And for a truly indulgent holiday dinner, serve it alongside a glass of chardonnay or pinot noir, which pairs beautifully with creamy, cheesy dishes. 🍷

How to Store and Reheat Leftovers 🧊

Refrigerate: Store leftovers in an airtight container for up to 4 days.
Freeze: Wrap tightly and freeze for up to 2 months.
Reheat: Bake covered at 350°F until hot and bubbly, or microwave individual portions for a quick side dish.
