Instructions

Step 1: Prepare the Potatoes

1. Preheat your oven to 375°F (190°C).

2. Lightly grease a 9 × 13-inch baking dish with butter.

3. Wash and peel the potatoes.

4. Slice the potatoes into thin, even rounds, approximately ⅛-inch thick.

5. Try to keep all slices similar in thickness so they cook evenly.

6. Place the sliced potatoes in a large bowl.

7. Season lightly with salt and black pepper.

8. Toss gently to distribute the seasoning.

Step 2: Prepare the Creamy Garlic Sauce

1. Place a medium saucepan over medium heat.

2. Add 3 tablespoons of butter and allow it to melt.

3. Add the minced garlic.

4. Cook for approximately 30–45 seconds until fragrant.

5. Sprinkle in the all-purpose flour.

6. Whisk continuously for about 1 minute to create a smooth mixture.

7. Slowly pour in the heavy cream while whisking.

8. Add the whole milk gradually.

9. Continue whisking until the sauce becomes smooth and creamy.

10. Add Italian seasoning, dried parsley, onion powder, salt, black pepper, and nutmeg.

11. Simmer gently for approximately 3–5 minutes until slightly thickened.

12. Add the grated Parmesan cheese.

13. Stir until the cheese melts completely.

14. Remove the saucepan from the heat.

Step 3: Arrange the Potatoes in the Baking Dish

1. Arrange the sliced potatoes in the prepared baking dish.

2. Slightly overlap the potato slices in neat rows or layers.

3. Continue arranging until the entire bottom of the dish is covered.

4. Add another layer of potatoes if necessary.

5. Make sure the slices are distributed evenly throughout the dish.

Step 4: Pour the Creamy Garlic Sauce

1. Take the prepared garlic Parmesan sauce.

2. Slowly pour the warm sauce over the sliced potatoes.

3. Distribute it evenly so the sauce reaches between the potato slices.

4. Use a spoon to gently move the potatoes if needed.

5. Make sure most of the potatoes are coated with the creamy mixture.

Step 5: Add the Cheese Topping

1. Sprinkle shredded mozzarella cheese over the potatoes.

2. Add grated Parmesan cheese evenly across the surface.

3. Sprinkle a little black pepper and dried parsley.

4. Make sure the cheese covers the top for a delicious golden finish.

Step 6: Bake Until Tender

1. Cover the baking dish tightly with aluminum foil.

2. Place it in the preheated oven.

3. Bake for approximately 35–40 minutes.

4. Carefully remove the foil.

5. Continue baking uncovered for another 20–25 minutes.

6. Check the potatoes by inserting a knife into the center.

7. They should be completely tender, and the sauce should be bubbling around the edges.

8. If the top needs more color, broil for 1–2 minutes, watching carefully.

Step 7: Rest and Garnish

1. Remove the baking dish from the oven.

2. Allow the potatoes to rest for approximately 10–15 minutes.

3. This helps the creamy sauce thicken and settle.

4. Sprinkle freshly chopped parsley over the top.

5. Add extra Parmesan cheese if desired.

6. Finish with freshly cracked black pepper.

Step 8: Serve and Enjoy

1. Carefully scoop out generous portions using a serving spoon or spatula.

2. Transfer the creamy potatoes onto individual serving plates.

3. Spoon some of the rich garlic Parmesan sauce over each serving.

4. Serve warm while the potatoes are tender and the sauce is creamy.

Tips for the Best Garlic Parmesan Potatoes

• Slice evenly: Thin, uniform potato slices cook more consistently.

• Choose Yukon Gold potatoes: They provide a naturally buttery flavor and creamy texture.

• Use fresh garlic: Freshly minced garlic gives the sauce a wonderful aroma.

• Grate Parmesan yourself: Fresh Parmesan melts more smoothly.

• Don’t skip the foil: Covering the dish initially helps the potatoes cook through.

• Allow resting time: Resting helps the sauce thicken before serving.

• Avoid boiling the cream: Keep the sauce at a gentle simmer.

Frequently Asked Questions (Q&A)

Q1: Can I use Russet potatoes instead of Yukon Gold?

Yes! Russet potatoes work very well and produce a soft, fluffy texture. Yukon Gold potatoes are slightly creamier and hold their shape better.

Q2: Do I need to boil the potatoes before baking?

No. Thinly sliced raw potatoes cook directly in the creamy sauce in the oven.

Q3: Can I prepare this recipe ahead of time?

Yes! You can prepare the sauce and slice the potatoes ahead of time. For the best color and texture, assemble shortly before baking. If assembling ahead, keep refrigerated and bake until fully tender.

Q4: Can I use milk instead of heavy cream?

Yes, but the sauce will be less rich. For a creamy result, use whole milk combined with a little extra butter.

Q5: What cheese works best for this recipe?

Parmesan and mozzarella are excellent choices. Gruyère, cheddar, and Monterey Jack also work beautifully.

Q6: How do I know when the potatoes are fully cooked?

Insert a sharp knife into the center. It should slide through the potato slices easily without resistance.

Q7: How can I make the sauce thicker?

Use the flour in the sauce as directed and allow the dish to rest for 10–15 minutes after baking.

Q8: Can I add onions or mushrooms?

Absolutely! Thinly sliced onions and sautéed mushrooms make delicious additions between the potato layers.

Q9: How should I store leftovers?

Store leftovers in an airtight container in the refrigerator for up to 3–4 days.

Q10: How do I reheat scalloped potatoes?

Reheat in the oven at 350°F (175°C), covered with foil, for approximately 15–20 minutes. Add a splash of milk or cream if needed.
