Understanding Kohlrabi: A Brief Overview
Before we dive into the cooking process, let’s take a moment to understand what kohlrabi is and its nutritional benefits. Kohlrabi is a cruciferous vegetable, belonging to the same family as cabbage, broccoli, and cauliflower. It’s a cool-season crop, typically grown in the spring or fall, and is characterized by its bulbous stem and leafy greens.
Kohlrabi is an excellent source of essential vitamins and minerals, including:
- Vitamin C: Boosts immune function and antioxidant properties
- Vitamin K: Essential for blood clotting and bone health
- Fiber: Supports healthy digestion and satiety
- Potassium: Helps regulate blood pressure and promotes overall cardiovascular health
Preparing Kohlrabi for Oven Roasting
To bring out the best flavor and texture of kohlrabi, it’s essential to prepare it properly before roasting. Here’s a step-by-step guide to get you started:
Choosing the Right Kohlrabi
When selecting kohlrabi, look for bulbs that are firm, compact, and have a vibrant green color. Avoid those with signs of wilting, yellowing, or soft spots. You can choose from two main varieties: green and purple. The green variety tends to be milder in flavor, while the purple variety has a slightly sweeter and nuttier taste.
Peeling and Trimming
Peel the kohlrabi bulb using a vegetable peeler, removing any tough, woody skin. Trim the ends and remove any leaves, as they can be a bit bitter. You can use the leaves in soups or sauté them as a side dish, but for oven roasting, it’s best to focus on the bulb.
Cutting and Slicing
Cut the peeled kohlrabi bulb into your desired shape and size. You can slice it into:
- Wedges: Cut the bulb into 1-inch thick wedges, perfect for roasting as a side dish.
- Cubes: Dice the kohlrabi into 1-inch cubes, ideal for adding to soups, stews, or casseroles.
- Slices: Thinly slice the kohlrabi, great for using in salads or as a topping for sandwiches.
