- 1/2 teaspoon fresh rosemary, chopped

Shopping List
- Produce: 1 pound Yukon Gold potatoes, 1 pound sweet potatoes, 1/2 pound parsnips, 1 teaspoon fresh thyme leaves, 1/2 teaspoon fresh rosemary
- Meat: 8 slices thick-cut bacon
- Dairy & Eggs: 4 tablespoons unsalted butter, 3 cups whole milk, 1 cup heavy cream, 1 1/2 cups Gruyère cheese, 1/2 cup Parmesan cheese
- Pantry: 4 tablespoons all-purpose flour, 1/4 teaspoon ground nutmeg, 1 teaspoon salt, 1/2 teaspoon black pepper
Instructions
- Preheat your oven to 375°F (190°C). Grease a 9×13 inch gratin dish or similar oven-safe baking dish.
- Cook the bacon: Lay bacon slices on a baking sheet and bake for 15-20 minutes, or until crispy. Remove, drain on paper towels, and once cool, crumble into pieces. Set aside.
- Prepare the root vegetables: Using a sharp knife or a mandoline slicer, thinly slice the peeled Yukon Gold potatoes, sweet potatoes, and parsnips to about 1/8-inch thickness. A mandoline is highly recommended for uniform slices, ensuring even cooking.
- Make the cream sauce: In a large pot or Dutch oven, melt the unsalted butter over medium heat. Whisk in the all-purpose flour and cook for 1-2 minutes, stirring constantly, to create a roux.
- Slowly whisk in the warm whole milk and heavy cream until no lumps remain and the mixture is smooth.
- Bring the sauce to a gentle simmer, stirring frequently, until it thickens, about 5-7 minutes.
- Remove from heat and stir in the chopped fresh thyme, rosemary, ground nutmeg, salt, and black pepper. Taste and adjust seasoning if needed.
- Assemble the gratin: Spread a thin layer of cream sauce on the bottom of the prepared gratin dish.
- Arrange a layer of mixed root vegetables (potatoes, sweet potatoes, parsnips) over the sauce, overlapping them slightly.
- Sprinkle a portion of the crumbled bacon and some of the shredded Gruyère cheese over the vegetable layer.
- Ladle another generous amount of cream sauce over the cheese and bacon.
- Repeat layers of vegetables, bacon, Gruyère, and sauce until all vegetables are used, ending with a layer of sauce.
- Cover the gratin dish tightly with aluminum foil.
- Bake for 60 minutes.
- Remove the foil. Sprinkle the remaining Gruyère and Parmesan cheese evenly over the top.
- Bake uncovered for another 15-20 minutes, or until the top is golden brown and bubbly, and the vegetables are tender when pierced with a fork.
- Let the gratin rest for 10-15 minutes before serving to allow the sauce to set.
Tips & Variations
- Achieving perfectly even slices for your root vegetables is crucial for uniform cooking. A mandoline slicer is a game-changer here, but if slicing by hand, just aim for consistent thickness.
- For the smoothest sauce, always warm your milk and cream before adding them to the roux. This simple trick helps prevent lumps and speeds up the thickening process.
- Don’t be afraid to customize! This gratin welcomes other root vegetables like carrots, celeriac, or even rutabaga. Just remember denser veggies might need a touch more baking time.
- While Gruyère and Parmesan are a classic duo, feel free to swap in your favorite melting cheeses like sharp cheddar, fontina, or a blend that suits your taste.
- To make entertaining a breeze, assemble this gratin up to a day in advance! Cover it tightly, refrigerate, and let it come to room temperature for about 30 minutes before baking. You might need to add an extra 10-15 minutes to the initial covered baking time.
Serving & Storage Suggestions
