- Cutting board and knife
- Vegetable peeler
- Cheese grater
- Aluminum foil

Step-by-Step Preparation
- Preheat the Oven
Set your oven to 350°F (177°C) and butter an 8×8-inch baking dish thoroughly. - Cook Aromatics and Vegetables
Melt the butter in a large saucepan over medium heat. Add minced garlic and cook for about 30 seconds until fragrant. - Add Main Ingredients
Stir in sliced potatoes, broccoli stems, heavy cream, chopped thyme, a pinch of nutmeg, salt, and pepper. Bring to a gentle boil over medium-high heat. Continue cooking and stirring for 1-2 minutes until the potatoes absorb cream and the mixture thickens slightly. - Add Cheese
Remove the pan from heat and mix in 1 cup of the grated Gruyere cheese until evenly distributed. - Assemble and Bake
Pour the mixture into the prepared baking dish, making sure potatoes and broccoli stems are spread evenly. Top with the remaining 1 cup Gruyere. Cover with foil and bake for about 35 minutes, or until potatoes are just fork-tender. - Finish Baking Uncovered
Remove the foil. Continue to bake for an additional 15 minutes, until the top is deliciously brown and bubbly. - Rest and Serve
Let the gratin cool for 10 minutes before serving, allowing the creamy interior to settle and flavors to meld.
