Learn to Cook with Root Vegetables in a Gratin Recipe

I love a good gratin recipe. I’ve had some stomach issues in the past few years and I’ve turned to a more plant based diet. The only root vegetable I had regularly in my diet before was the potato. I’ve decided it was time to experiment with other root veggies, and learn just how delicious they are.

Not only am I learning how to cook the root vegetables in various recipes, I’m also learning how to grow them myself, and since I hate wasting food I have to find delicious and engaging recipes to keep my taste buds alive. One of the diets I had to do to reset my stomach was rather devoid of flavor, I’ve missed flavor, so I’ve been paying particular attention on the enjoyment of eating what I cook.

What I like about this recipe is that you can throw in a bunch of different root veggies, or just focus on one. And cheese. I love cheese. But besides the different ways you can eat a potato, what do you do with yams, beets, parsnips, turnips, rutabagas, carrots, yuca, kohlrabi, onions, garlic, celery root (or celeriac), horseradish, daikon, turmeric, jicama, Jerusalem artichokes, radishes, and ginger?

Finding ways to cook with turmeric and ginger also have the addition of health benefits. Both ginger and turmeric have anti-inflammatory benefits for the human body. If you know you have inflammation within your body, it might be something you want to check out.
