Roasted radishes might sound unusual, but they bring a sweet, mellow flavor that pairs beautifully with tender baby potatoes and sharp cheddar cheese in this cheesy bake. This dish is the kind of comforting, simple recipe that works well for weeknights or a laid-back weekend meal. By parboiling the potato slices first, you ensure they cook evenly and become perfectly tender in the oven without a long baking time. The addition of Greek yogurt gives the bake a creamy tang without heaviness, making the texture light yet indulgent. If you enjoy cheesy vegetable casseroles like the baked chicken and potato casserole with creamy cheese topping, you’ll find this a fresh twist that’s equally satisfying.

Ingredients
- 1 pound (450 g) baby potatoes, thinly sliced
- 2 cups (about 200 g) radishes, halved
- 1 small onion, thinly sliced
- 2 large eggs
- 3/4 cup (180 ml) plain Greek yogurt
- 1 cup (100 g) shredded mature cheddar cheese
- 1 teaspoon dried thyme
- 1/2 teaspoon salt
Ingredient Notes
Baby potatoes are ideal here because their thin slices cook quickly and become creamy without breaking apart. Radishes, when roasted, lose their peppery bite and become pleasantly sweet—so don’t skip this step if you want balanced flavors. Greek yogurt works better than sour cream in this recipe since it holds its structure when baked and adds a nice tang. Mature cheddar melts well and provides that rich, sharp cheesiness essential for a golden crust. For herbs, dried thyme gives depth, but fresh thyme or rosemary can work as well if you want a slightly different aromatic profile.
Kitchen Tools Needed
- 9-inch (23 cm) baking dish
- Large saucepan for simmering potatoes
- Mixing bowl
- Whisk or fork
- Sharp knife and chopping board
- Measuring cups and spoons
Step-by-Step Instructions
- Preheat your oven to 375°F (190°C). While the oven heats, bring a large pot of salted water to a boil.
- Add the thinly sliced baby potatoes to the boiling water and simmer for 6 minutes. This partial cooking ensures they will be tender in the final bake without drying out or requiring extra oven time.
- Drain the potatoes thoroughly, allowing them to cool just enough so you can handle them safely.
- Grease a 9-inch (23 cm) baking dish lightly with butter or oil. Arrange the parboiled potato slices, halved radishes, and thinly sliced onion evenly in the dish.
- In a separate bowl, whisk together the eggs, Greek yogurt, dried thyme, and salt until smooth and combined. Pour this mixture carefully over the vegetables, making sure it spreads evenly to coat them.
- Scatter the shredded mature cheddar cheese evenly across the top of the dish.
- Bake in the preheated oven for 35 to 40 minutes. You’ll know it’s done when the radishes are tender (test with a fork), the center is set and no longer jiggly, and the cheese on top has turned a lovely golden brown.
- Remove from the oven and let the bake rest for about 10 minutes — this resting time helps the custard set and makes slicing easier without the filling running out.
Pro Tips
- Don’t slice the potatoes too thick or they won’t cook through evenly—aim for about 1/4 inch (6 mm).
- Make sure to drain potatoes well after simmering; excess water could make the bake watery.
- For best texture, evenly layer the vegetables without overpacking the dish.
- You can swap dried thyme for fresh thyme or Italian herb mix if preferred—just use about a tablespoon of fresh instead of a teaspoon dried.
- Adding a little garlic powder or minced fresh garlic to the egg mixture can deepen the flavor if you like.
- If you want a richer dish, try mixing a bit of grated Parmesan into the cheddar topping before baking.
Radishes roasting in this dish add a surprising sweetness to complement the potatoes, and it’s wonderful served along with a hearty salad or some roast chicken. If you enjoy vegetable bakes, this recipe shares a spirit with the comforting flavors found in the broccoli and cauliflower bake with roasted peppers and cheese, but with its distinct twist on root vegetables.
Common Mistakes
- Skipping the parboil step results in undercooked potatoes while the radishes and onions soften well.
- Not draining the potatoes thoroughly can leave the dish soggy.
- Using thick potato slices that don’t cook through during baking.
- Adding too much salt before tasting, especially as the cheese topping adds more seasoning.
- Rushing to cut immediately out of the oven—letting it rest allows it to firm up.
Variations
- Swap radishes for turnips or white asparagus for different seasonal twists.
- Use crème fraîche or sour cream instead of Greek yogurt for a richer custard.
- Add cooked bacon or pancetta pieces for a smoky, savory bite.
- Stir in fresh herbs like parsley or chives after baking for freshness.
Serving Suggestions
This bake makes a fantastic side for roast meats like pork or chicken but is comforting enough to enjoy as a vegetarian main with a crisp green salad. It pairs especially well with tangy condiments like chutney or a drizzle of mustard vinaigrette. Leftovers are great for packed lunches or reheated as a quick dinner.
Storage Instructions
Store any leftovers cooled completely in an airtight container in the refrigerator. It will keep well for 3 to 4 days. Avoid freezing, as the texture of the yogurt and vegetables can become watery and lose their structure when thawed.
Reheating Tips
Reheat gently in a 350°F (175°C) oven for about 15–20 minutes to warm through thoroughly and crisp the top again. Using a microwave can work in a pinch but may cause the bake to lose its creamy texture.

Frequently Asked Questions
Can I use regular yogurt instead of Greek yogurt?
Regular yogurt tends to be thinner and more watery, which could affect the bake’s consistency. Greek yogurt works best because it’s thicker and creamier, helping the custard set nicely.
Is it necessary to parboil the potatoes?
Yes, parboiling ensures the potatoes cook through evenly with the radishes and don’t dry out during baking.
What if I don’t have baby potatoes?
Use any waxy potato sliced thinly, but be sure to adjust cooking time if the slices are thicker or from larger potatoes.
Can I prepare this dish ahead of time?
You can assemble it a few hours ahead and keep it in the fridge until ready to bake. Just let it come close to room temperature before baking for best results.
Can I add other vegetables?
Yes, thinly sliced carrots or zucchini can work, but adjust baking time to ensure all vegetables are tender.
Enjoy experimenting with this cozy, cheesy bake, a great way to bring radishes out of their usual salad role and into a warm and cheesy centerpiece on your table.
