Kohlrabi
Petra’s LifeFuel Tip: Meet Kohlrabi – Your New Favorite Veggie
Kohlrabi might look a little unusual if you’re not familiar with it, but don’t let its alien-like shape fool you—it’s a nutritional powerhouse! A proud member of the cruciferous vegetable family (think broccoli, cabbage, and kale), kohlrabi is rich in antioxidants, vitamin C, and fiber, supporting immunity, gut health, and overall well-being.
What’s even better? Kohlrabi is as versatile as it is healthy. While it shines in this creamy casserole, it’s also delicious raw—think crisp, slightly sweet, and refreshing, almost like a mix of apple and mild radish. Slice it into sticks for snacking, add it to slaws, or toss it into salads for a satisfying crunch. If kohlrabi is new to your kitchen, you’re about to fall in love!

Tips for Best Flavor & Substitutions
Steam the kohlrabi first: Don’t skip this step! Steaming the kohlrabi for 15–20 minutes in a steamer pot is the secret to achieving that soft, potato-like texture that makes this casserole so comforting. I’ve tried baking it raw, and no matter how long it stayed in the oven, the texture just didn’t compare.
Short on time? Steam the kohlrabi in a pressure cooker (like an Instant Pot) instead—3–5 minutes on high pressure with a quick release works beautifully. Just be careful not to overcook—it should be tender, not mushy.
Want a potato twist? Craving the classic version? Replace the top layer of kohlrabi with thinly sliced potatoes (about ¼ inch thick) for an extra comforting touch.
Sauté the chicken first: A quick 3–5 minute sauté with onions and spices before baking enhances flavor and reduces bake time. No need to cook it fully—it will finish in the oven.
Season generously: The spice amounts in the recipe are my personal favorite balance, but feel free to adjust them to your taste. For the boldest flavor, lightly season each kohlrabi layer with a pinch of salt, caraway, and cumin as you assemble the casserole.
Optional cheesy finish: If you’re not avoiding dairy, sprinkle grated Gouda or cheddar on top during the last 10–15 minutes of baking for a delicious golden crust. Even without cheese, this casserole is pure comfort.
Protein swap: Prefer pork? Simply use thinly sliced pork loin instead of chicken.
Choose the best ingredients: Whenever possible, opt for organic, locally grown vegetables and pasture-raised poultry. If you can find biodynamic produce, even better—your body (and the planet) will thank you.
Petra’s LifeFuel Tip: How to Prep Kohlrabi Like a Pro
Kohlrabi’s tough outer skin can seem intimidating, but prepping it is simple:
1. Trim the leaves and stems – they’re edible, so save them for soups or sautés.
2. Slice off both ends to create a stable base.
3. Peel away the thick outer layer with a sharp knife or vegetable peeler until you reach the pale, tender flesh.
Now your kohlrabi is ready to shine—whether you steam it for this casserole or enjoy it raw for extra crunch!

Petra’s LifeFuel Tip
One of my favorite ways to enjoy this casserole is alongside a crisp leafy green salad tossed in a simple, nourishing dressing—perfect for one portion. I make it by whisking together 1 tablespoon of olive oil, 1 teaspoon of flaxseed oil, 1 tablespoon of fresh lemon juice, 1 clove of garlic (minced), and a pinch of salt to taste. For an extra boost of creaminess and healthy fats, I top the salad with about ½ of a ripe avocado, cubed—it pairs beautifully with the casserole’s creamy texture.
Storage Tips
Whether you’re saving leftovers for tomorrow’s lunch or stocking the freezer for busy days, this casserole keeps beautifully. Here’s how to store it for the best flavor and texture:
Petra’s LifeFuel Tip
This casserole freezes well thanks to its creamy coconut-mustard sauce, but keep in mind that the kohlrabi may soften a bit after thawing. For the best texture, freeze in airtight containers soon after baking, then thaw in the refrigerator overnight before reheating. The flavors will still be delicious—the texture will just be slightly more tender.

Low-Carb Chicken Kohlrabi Casserole
Creamy, flavorful, and packed with veggies, this low-carb casserole is a comforting dish you’ll want to make again and again.
- Total Time: 1 hour 25 minutes
- Yield: 6 1x
Ingredients
- 3 lbs kohlrabi (about 5–6), peeled and sliced 1/4-inch thick
- 1 lb boneless, skinless chicken breast, cut into 1/4-inch strips
- 6 oz onion, halved lengthwise and thinly sliced
- 6 oz baby spinach, chopped
- 2 tbsp ghee or extra virgin olive oil, divided
- 4–6 cloves garlic, minced, divided
- 2 tsp ground caraway seeds, divided (plus extra for sprinkling)
- 1 1/2 tsp ground cumin, divided (plus extra for sprinkling)
- 2 tsp sea salt, divided
- 1/4 tsp freshly ground black pepper
- 1 1/2 cups full-fat coconut milk (12 oz)
- 3 tbsp Dijon mustard (1.5 oz)
Instructions
Steam the Kohlrabi
Steam the sliced kohlrabi in a steamer pot for 15–20 minutes, until tender but not mushy. Alternatively, use a pressure cooker (such as an Instant Pot): cook on high pressure for 3–5 minutes, then quick release. Be careful not to overcook—the slices should be fork-tender but still hold their shape.
Preheat Oven
Preheat the oven to 350 degrees Fahrenheit (175°C).
Sauté Chicken
In a medium skillet, heat 1 tablespoon of ghee or extra virgin olive oil over medium heat. Add the onion and cook for 2–3 minutes, until translucent. Add the chicken along with ½ teaspoon of salt, ½ teaspoon of ground caraway, ½ teaspoon of ground cumin, and half of the garlic. Sauté for about 3 minutes—no need to cook the chicken all the way through, as it will finish baking in the oven.
Prepare Coconut Milk Mixture
In a small bowl, whisk the coconut milk, Dijon mustard, remaining garlic, 1½ teaspoons of ground caraway, 1 teaspoon of ground cumin, ½ teaspoon of salt, and ¼ teaspoon of freshly ground black pepper. Mix until well combined.
Assemble the Casserole
Once the kohlrabi is steamed, transfer it to a large bowl and toss with the remaining 1 tablespoon of ghee. In a large baking dish (about 9×13 inches), begin layering:
- First layer: kohlrabi slices, lightly seasoned with a pinch of salt, ground caraway, and cumin.
- Second layer: sautéed chicken.
- Third layer: more kohlrabi, again lightly seasoned.
- Fourth layer: chopped spinach, lightly salted.
- Final layer: remaining kohlrabi, seasoned with another pinch of salt, caraway, and cumin.
Add the Sauce
Pour the coconut milk mixture evenly over the layered casserole. Tilt the dish gently from side to side so the sauce seeps through all layers.
Bake the Casserole
Bake uncovered for 45–55 minutes, until the top is lightly golden and the sauce is mostly absorbed. If you’re adding cheese, sprinkle grated Gouda or cheddar over the top about 15–20 minutes before the baking time is up, then return to the oven to melt and lightly brown.
