Ingredients

• 5 lbs Russet potatoes, peeled and sliced 1/8 inch thick
• 2 cups onions, chopped small
• 6 cloves garlic, minced
• 1/4 cup butter
• 1/4 cup flour
• 1 1/2 cups vegetable broth
• 1 1/2 cups heavy cream
• 1 Tbsp salt
• 2 tsp black pepper
• 2 tsp Slap Ya Mama seasoning
• 8 oz sour cream
• 3 cups cheddar cheese, grated (divided)
• 1 cup pepper jack cheese, grated
• 1 cup freshly grated Parmesan cheese

Step-by-Step Instructions

1. Preheat and prepare: Preheat your oven to 400°F (200°C). Spray a 14×11.5×2.25 inch baking dish with non-stick spray.
2. Slice potatoes: Peel the Russet potatoes and slice them thinly to about 1/8 inch thickness. Uniform slicing helps the potatoes cook evenly.
3. Sauté onions and garlic: In a large frying pan, melt the butter over low heat. Add the chopped onions and minced garlic, sautéing gently for 4–5 minutes until soft and fragrant but not browned.
4. Make the roux base: Sprinkle the flour over the sautéed onion and garlic mixture. Stir constantly and cook for about 2 minutes to remove the raw flour taste.
5. Add liquids and seasonings: Slowly pour in the vegetable broth while stirring continuously, then add salt, black pepper, Slap Ya Mama seasoning, and heavy cream. Continue stirring until the sauce thickens and just before it reaches boiling point, remove the pan from the heat.
6. Incorporate cheese: Stir in 2 cups of shredded cheddar cheese into the hot sauce until melted and smooth.
7. Layer the dish: Start by arranging one-third of the potato slices evenly along the bottom of the baking dish. Spread one-third of the sour cream over the potatoes, then pour one-third of the cheesy sauce over the sour cream layer. Sprinkle one-third of the Parmesan, pepper jack, and remaining cheddar cheeses evenly on top.
8. Repeat layering: Repeat this layering process two more times, ending with a generous layer of cheddar cheese on top.
9. Bake covered: Cover the baking dish tightly with foil and place it in the preheated oven. Bake for 1.5 to 2 hours, or until potatoes are tender and the sauce is bubbly.
10. Brown the top: Remove the foil 15-20 minutes before the end of baking to allow the cheese to brown and develop a crispy golden crust.
11. Rest before serving: Once baked, let the scalloped potatoes rest for 15 minutes before serving to allow the sauce to thicken and flavors to meld.

Pro Tips for Perfect Cheesy Garlic Scalloped Potatoes

• Slice evenly: A mandoline slicer can speed up and improve uniformity in slicing potatoes to a consistent thickness of about 1/8 inch.
• Don’t skip resting: Letting the dish rest post-baking helps the layers set, making it easier to serve without collapsing.
• Low and slow baking: Baking at 400°F ensures even cooking without drying out the cheesy sauce—resist turning up the heat to speed up baking.
• Use freshly grated cheese: Pre-shredded cheese often contains anti-caking agents which can affect melting quality; freshly grate your cheeses for creamier results.
• Season layers: Adding seasoning to the sauce and being generous with Slap Ya Mama seasoning imparts layers of flavor making each bite exciting.

Variations and Substitutions

• Healthier option: Substitute heavy cream with full-fat coconut milk or a mix of almond milk and cashew cream for a dairy-free twist without sacrificing creaminess.
• Cheese swaps: For a milder flavor, replace pepper jack cheese with mozzarella or Monterey Jack. For extra sharpness, add a bit of smoked gouda.
• Herbs and spices: Try mixing in thyme, chives, or rosemary into the sauce to add aromatic herb notes.
• Vegetable add-ins: Fold in blanched spinach, mushrooms, or roasted red peppers between layers for added texture and nutrition.
• Sodium adjustments: Reduce salt if using flavorful cheeses or broth, or opt for low-sodium vegetable broth.

Storage and Reheating Tips

Store any leftovers in an airtight container in the refrigerator for up to 4 days. When ready to reheat, cover the potatoes with foil and warm in a 350°F (175°C) oven for 25–30 minutes until heated through. To revive the crispy cheese crust, remove the foil for the last 5-10 minutes of reheating. Avoid microwaving as it can make the dish watery and unevenly heated.

FAQ

Can I use different types of potatoes?

Russet potatoes are ideal due to their starchy texture, which helps thicken the sauce naturally. Yukon Golds can be used but expect a slightly creamier and less fluffy texture.

Is it necessary to peel the potatoes?

Peeling ensures a smooth texture and uniform cooking, but if you prefer a rustic taste with added nutrients, you can leave the skins on, just be sure to wash them well.

Why does the recipe call for vegetable broth?

The vegetable broth adds depth of flavor and moisture without overpowering the cheesy garlic sauce, making it a perfect base for this vegetarian-friendly dish.

Can I prepare this dish ahead of time?

Yes! Assemble the casserole up to the baking step, cover tightly, and refrigerate overnight. When ready, allow it to come to room temperature before baking as directed, adding 10–15 extra minutes if needed.

How can I make this dish vegan?

Use plant-based butter, non-dairy milk such as oat or cashew cream for the sauce, and vegan cheese substitutes. Replace sour cream with vegan sour cream options.
