How to Make Baked Rutabaga Casserole
-
Peel and Slice: Start by peeling the rutabaga and cutting it into thin crescent slices. Also, slice the onion into thin rings to ensure even cooking.
-
Sauté Onions: Preheat an oven-safe pan over medium heat. Add the Earth Balance or margarine, and when it melts, toss in the onion slices. Sauté for about 10 minutes until they’re golden brown. Set them aside in a small bowl.
-
Layer Rutabaga: In the same pan, arrange the rutabaga slices in a single layer, topping them with the sautéed onions. Finish with another layer of rutabaga on top. Cover the pan with a lid and cook on medium heat for 10-15 minutes, or until the bottom layer is brown and the middle slices are tender.
-
Preheat Oven: While the casserole is cooking, preheat your oven to 375°F using the grill setting. This will help achieve that perfect golden topping.
-
Add Eggs: Once the bottom rutabagas are browned, pour the whisked eggs over the top layer. Transfer the pan to the preheated oven and bake for about 5 minutes, checking frequently, until the eggs are set and browned slightly on top.
-
Season and Serve: Finally, sprinkle the casserole with salt and freshly ground pepper. Serve it warm alongside a fresh side salad for a delightful meal!
Optional: Fresh herbs like parsley or chives make a lovely garnish.

Expert Tips for Baked Rutabaga Casserole
Prep Rutabaga Properly: Slice the rutabaga evenly for even cooking; uneven pieces may cook at different rates and lead to a less consistent texture.

Use Quality Ingredients: Opt for high-quality margarine or butter and fresh eggs for the best flavor result. Fresh ingredients make all the difference in this comforting dish!

Baked Rutabaga Casserole Recipe FAQs
How do I choose the right rutabaga?
Absolutely! When selecting a rutabaga, look for ones that are firm and heavy for their size, with smooth skin. Avoid any that have dark spots or soft spots, as these indicate overripeness. A good rutabaga will have a slightly sweet aroma and be free from blemishes.
How long can I store leftovers in the fridge?
You can store your Baked Rutabaga Casserole in an airtight container for up to 3 days in the fridge. It’s best to let it cool completely before sealing it up to preserve its freshness. When you’re ready to eat, just reheat it gently to enjoy that comforting flavor once more.
Can I freeze the Baked Rutabaga Casserole?
Absolutely! To freeze, first let the casserole cool completely. Then, wrap it tightly in plastic wrap followed by aluminum foil. This method prevents freezer burn and keeps it delicious. It can stay fresh in the freezer for up to 2 months. When you’re ready to enjoy it, thaw the casserole overnight in the fridge and then reheat gently in the oven at 350°F for about 20-25 minutes.
What should I do if my rutabaga doesn’t cook evenly?
Very! If you encounter uneven cooking, it likely stems from uneven slicing. For future attempts, be sure to slice the rutabaga into uniform crescent slices to ensure even cooking. If you find that some pieces are undercooked, you can always pop the casserole back on the stove or in the oven for a few more minutes until everything is tender.
Is this recipe suitable for people with allergies?
Yes, but! This Baked Rutabaga Casserole contains eggs and can be modified for vegans by using a substitute like flax egg (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water, let sit for 5 minutes).
