How to Make Turnip Casserole

Preheat the Oven:
Start by placing an 8-inch square or 2-quart baking dish on the middle rack of your oven and preheat to 400°F. This ensures even cooking once you’re ready to pop your casserole in.
Sauté the Onions:
Carefully remove the baking dish and add the sliced onion, olive oil, ¼ teaspoon salt, and ⅛ teaspoon pepper. Toss well to coat. Cover with foil and return to the oven, baking and stirring every 10 minutes until golden and tender, about 30 minutes.
Prepare the Turnips:
While the onions bake, peel and slice your turnips into ⅛-inch thick rounds. For safety and stability, cut them in half before slicing into thick half moons.
Make the Sauce:
In a medium saucepan, melt 2 tablespoons of butter over medium heat. Whisk in the flour, cooking for 1-2 minutes until lightly golden. Gradually add warmed milk and half-and-half, stirring until bubbling and thickened, about 5 minutes. Mix in thyme, remaining salt, and pepper, then remove from heat.
Layer the Casserole:
Take the onions out of the oven and transfer them to a bowl. Lower the oven temperature to 350°F. In the baking dish, layer half of the turnips followed by half of the sautéed onions. Spread half of the creamy sauce over the top and sprinkle with half of the cheese. Repeat these layers and cover the dish with foil.
Bake Until Tender:
Bake the casserole for about 50 minutes, or until the turnips are tender when pierced with a knife tip.
Prepare the Topping:
While the casserole bakes, melt the last tablespoon of butter in a small bowl in the microwave. Stir in the panko and paprika, crushing with a fork until the mixture is evenly moistened.
Add the Crunch:
After the initial baking time, sprinkle the panko mixture over the top. Return to the oven and bake uncovered for an additional 15 to 20 minutes, until the topping is golden and crunchy. Once done, let the casserole cool for 15 minutes before serving. Finish with a sprinkle of freshly chopped parsley!

Optional: Drizzle with a bit more olive oil before serving for an extra touch of flavor.

Expert Tips for Turnip Casserole

Choosing Turnips: Select firm, unblemished turnips; avoid soft or sprouted ones for the best flavor and texture in your Turnip Casserole.
Consistent Slicing: Slice the turnips evenly to ensure uniform cooking. Uneven pieces can result in some turnips being undercooked while others are mushy.
Layering Technique: Start with a layer of onions at the bottom. This prevents sticking and adds moisture while baking, enhancing the overall texture of your casserole.
Sauce Thickness: Whisk continuously when making the sauce to prevent lumps. A well-mixed sauce is key to your Turnip Casserole’s creamy consistency.
Panko Perfection: For an extra crunchy topping, mix the panko with a bit of olive oil or melted butter. It can prevent the topping from burning and adds more flavor.
Let it Rest: Allow the casserole to cool for 15 minutes before serving. This helps it set, making it easier to serve and enhancing the flavors!
