1. Preheat your oven to 375°F and grease a 9×13 inch casserole dish. Don’t skip the greasing or you’ll regret it later.
2. In a skillet over medium heat, cook the ground turkey, diced onion, and minced garlic until the turkey is actually browned (not just gray) and the onion is soft, about 8-10 minutes. Break up the meat as you go.
3. Stir in the thyme, salt, and pepper. Let those flavors get to know each other for a minute.
4. Add the chicken broth and let it simmer for about 5 minutes until slightly reduced. This creates that flavorful base. Remove from heat.
5. While that’s simmering, trim the tops from your radishes and set them aside. Slice the radishes as thinly as you can—think paper-thin. Chop the radish tops like you would spinach.
6. In your prepared casserole dish, layer half of those sliced radishes on the bottom. They’ll overlap and that’s totally fine.
7. Spoon the turkey mixture evenly over the radishes, spreading it out to cover them.
8. Top with the remaining radish slices and then all those chopped radish tops.
9. Pour the heavy cream over the whole thing—it’ll look like a lot but trust the process.
10. Sprinkle that shredded cheddar cheese generously over the top.
11. Cover the dish with foil and bake for 30 minutes. Then remove the foil and bake for another 15 minutes until it’s bubbly and golden on top.
12. Let it rest for 5 minutes before serving. This lets everything settle and makes it easier to portion.

The radish tops are surprisingly nutritious, packed with vitamins A, C, and K. This casserole provides a good balance of protein from the turkey and beneficial nutrients from the radishes and greens.

Notes:

• Slice those radishes thin. Thick slices won’t cook through properly and you’ll end up with crunchy spots.
• Check your radish greens. Only use fresh, vibrant tops. Wilted or yellowing greens taste bitter.
• Every oven runs differently, so trust your eyes. Some ovens might need a few extra minutes to get that golden top.
• Don’t skip the resting time. Hot casserole straight from the oven is too liquidy to serve nicely.
• The radishes will soften and taste mild when cooked. If you think you don’t like radishes, try this—they’re nothing like raw ones.

Storage Tips:

Refrigerator: Store covered in the fridge for up to 4 days. The flavors actually develop more overnight, so leftovers are fantastic.

Reheating: Microwave individual portions for 2-3 minutes, or reheat the whole casserole covered with foil in a 350°F oven for 20 minutes.

Don’t freeze this casserole. The cream and radishes don’t freeze well. You’ll end up with a watery, separated mess when you thaw it. Trust me, I learned this the hard way.

Make-ahead: Assemble completely and refrigerate up to 24 hours before baking. Add 10-15 minutes to the covered baking time.

Serving Suggestions:

• With Crusty Bread: A good sourdough or French bread is perfect for soaking up the creamy sauce.
• Simple Side Salad: Balance the richness with a light mixed green salad dressed with lemon vinaigrette.
• Roasted Vegetables: Serve alongside roasted Brussels sprouts or green beans for a complete meal.
• Over Rice or Quinoa: Spoon this over grains to stretch it further and soak up every bit of that sauce.

Mix It Up (Recipe Variations):

Cheesy Turkey Radish Casserole: Double the cheese and mix half into the turkey layer before topping with the rest. Use a combination of cheddar and gruyere for extra richness.

Spicy Turkey Casserole: Add 1/2 teaspoon red pepper flakes to the turkey mixture and swap cheddar for pepper jack cheese. Perfect for those who like heat.

Herbaceous Radish Top Casserole: Mix in 1/4 cup fresh chopped herbs (parsley, dill, or chives) with the radish tops for bright, fresh flavor.

Dairy-Free Turkey Radish Casserole: Use coconut cream instead of heavy cream and skip the cheese or use vegan cheese. The texture changes slightly but it’s still delicious.

What Makes This Recipe Special:

This turkey and radish top casserole celebrates the zero-waste cooking philosophy by transforming typically discarded radish greens into a star ingredient. Radish tops have been eaten in European and Asian cuisines for generations but are often overlooked in modern American cooking. The layering technique creates distinct flavors in each bite while allowing the radishes to soften and sweeten during baking, completely transforming their raw peppery taste into something mild and comforting.
