Ingredients

• 2 lbs (approx. 1 kg) rutabaga, peeled and cut into 1-inch cubes
• 1 cup (240ml) heavy cream (or half-and-half for a lighter version)
• 2 tablespoons unsalted butter, melted, plus 2 tablespoons cold butter, cubed (for topping)
• 1 large egg, lightly beaten
• 2 tablespoons dark molasses or maple syrup (or to taste, see notes)
• 1 teaspoon ground ginger
• ½ teaspoon ground nutmeg
• ¼ teaspoon white pepper (optional, but traditional)
• 1 teaspoon salt, or to taste
• ½ cup (approx. 50g) plain breadcrumbs (for topping, use gluten-free breadcrumbs for GF option)
• Fresh parsley, chopped (for garnish, optional)

Directions

1. Prep the Rutabaga: Preheat your oven to 375°F (190°C). Peel the rutabaga thoroughly, removing any waxy coating. Cut the rutabaga into uniform 1-inch cubes. Place the cubes in a large pot and cover with cold, salted water. Bring to a boil, then reduce heat and simmer until the rutabaga is very tender and easily mashable with a fork, about 20-30 minutes. Don't rush this step; undercooked rutabaga will result in a grainy casserole.
2. Drain and Steam-Dry: Once tender, drain the rutabaga thoroughly in a colander. Return the drained rutabaga to the hot, empty pot over low heat for 2-3 minutes, stirring occasionally. This step is crucial for evaporating excess moisture and preventing a watery casserole.
3. Mash the Rutabaga: Remove the pot from the heat. Mash the rutabaga until smooth or to your desired consistency. Some prefer a rustic mash with a few small lumps, while others aim for a completely smooth puree. A potato masher works well for a rustic texture; a food processor can achieve a smoother result.
4. Mix the Casserole Base: Stir the heavy cream, 2 tablespoons melted butter, beaten egg, molasses (or syrup), ginger, nutmeg, white pepper (if using), and salt into the mashed rutabaga. Taste and adjust seasoning as needed. The mixture should be lightly sweet, savory, and well-balanced. It should be thick, like a soft-serve ice cream or thick porridge, not runny.
5. Prepare for Baking: Transfer the rutabaga mixture into a lightly buttered 8x8-inch (or similar 2-quart) baking dish. Smooth the top with a spatula. Traditionally, you can score the top with the tines of a fork in a crosshatch or diagonal pattern for a classic Finnish look.
6. Add Topping and Bake: In a small bowl, combine the breadcrumbs with the remaining 2 tablespoons of cold butter cubes. Sprinkle this mixture evenly over the top of the rutabaga casserole.
7. Bake to Perfection: Bake for 50-60 minutes, or until the casserole is bubbling around the edges, the top is golden brown and crispy, and the internal temperature reaches at least 165°F (74°C). The casserole should be set and not jiggly in the center.
8. Serve: Let the Lanttulaatikko rest for 5-10 minutes before serving. Garnish with fresh parsley, if desired.
