Instructions
- Prepare Ingredients: Finely slice all onions and potatoes into thin coins. If no mandoline, use a sharp knife. Slice evenly (~¼” thick).
- Shred Cheeses: Grate Gruyere and sharp white cheddar.
- Make Cheese Sauce: Heat pot, melt butter, whisk in flour and milk to make roux. Add in cheeses, salt, onion dip mix, onion powder, and Worcestershire sauce. Whisk until smooth.
- Assemble: Preheat oven. Layer ⅓ of cheese mixture in a greased casserole dish. Stack potatoes and onions, pour cheese sauce over, and top with remaining gruyere.
- Bake: Cover and bake at 350°F for 45 mins. Broil uncovered for 3-5 mins until golden.
- Garnish and Serve: Top with rosemary and green onion. Serve warm.
Notes
- If using a round dish, arrange potatoes in a circular pattern. For square or rectangle dishes, align in columns.
- Use a larger dish or split into two pans to prevent cheese overflow. Place a tray under for spillage.
- Spray foil with cooking spray to prevent cheese sticking. Store covered in the dish for up to 4 days or freeze for up to 3 months.
