Preparing the Prime Rib:
1. Room Temp: Remove prime rib from fridge 2-3 hours prior. Pat dry.
2. Prepare Rub: Combine olive oil, minced garlic, rosemary, thyme, salt, pepper. Rub generously.
3. Sear (Optional): Preheat large skillet. Sear roast on all sides until browned (2-3 mins/side).
4. Roast: Preheat oven 450°F (230°C). Place seared prime rib, fat-side up, on rack. Roast 15 mins, then reduce oven to 325°F (160°C). Roast until thermometer reaches 120-125°F (49-52°C) for medium-rare (1.5-2.5 hours).
5. Rest: Transfer roast to carving board, tent with foil, rest 20-30 minutes for juicy results.
Preparing the Scalloped Potatoes:
1. Preheat & Dish: Preheat oven 375°F (190°C). Butter a 9×13 inch baking dish.
2. Make Béchamel: In saucepan, melt butter. Whisk in flour 1 min. Gradually whisk in warmed milk/heavy cream until thick (5-7 mins). Stir in salt, white pepper, nutmeg. Remove from heat; stir in 1 cup Gruyère/Parmesan until melted.
3. Layer: Arrange 1/3 sliced potatoes, pour 1/3 sauce. Repeat twice more.
4. Bake: Cover dish with foil; bake 45 mins. Remove foil, sprinkle remaining 1/2 cup Gruyère. Bake uncovered 25-35 mins, until tender and golden.
5. Rest: Let potatoes rest 10-15 minutes before serving.
Expert Tips
Perfection hinges on details. Prime rib: use meat thermometer, pull slightly before target temp. Carve against grain. Potatoes: slice uniformly thin (mandoline helps). Warm milk/cream for lump-free béchamel. Don’t rush sauce. Allow both to rest; vital for succulent meat and set potatoes, enhancing flavor/texture.
Variations
Personalize your feast. Prime rib: consider marjoram/smoked paprika rub, or a horseradish crust. Scalloped potatoes: experiment with sharp white cheddar, Fontina, or cheese blend. Caramelized onions or sautéed mushrooms add richness. Garlic powder in sauce amplifies warmth. Fresh chives/parsley adds color.

Conclusion
Bringing together majestic prime rib and creamy scalloped potatoes creates a meal that transcends the ordinary – a symphony of textures and flavors. This dinner is an experience, a celebration. With these instructions and tips, you’re equipped to create a masterpiece. Gather ingredients, embrace the process, and savor every exquisite bite. Happy cooking!
