Why I Love This Recipe

This dish hits all the marks: it’s comforting yet lightcrispy yet tender, and infused with garlicky goodness and fresh thyme. It’s incredibly versatile—you can use cod, haddock, halibut, or even tilapia—and it pairs well with just about any veggie or dipping sauce you like. The layered lemon slices and fresh thyme add a gorgeous finish that’s as fragrant as it is tasty.


Ingredients

  • 4 skinless cod fillets (6 to 8 oz each)
  • 1 ½ lbs russet potatoes, sliced into ¼-inch rounds
  • 2 tablespoons olive oil
  • 3 garlic cloves, minced
  • 4 sprigs fresh thyme + 1 teaspoon minced thyme
  • 1 lemon, thinly sliced
  • Salt and pepper to taste

Swaps and Notes

  • Use sweet potatoes for a colorful and slightly sweeter twist.
  • Try rosemary or dill in place of thyme for a different flavor profile.
  • Add a side of green beans, asparagus, or peas for extra color and nutrition.

Step-by-Step Instructions

1. Prep the Oven & Potatoes

Preheat oven to 425°F. Toss potato slices with olive oil, garlic, minced thyme, salt, and pepper. Arrange on a lined or sprayed baking sheet in a single layer.

2. Roast the Potatoes

Bake the potatoes on the lower-middle rack for 35 minutes until golden and starting to crisp.

3. Season the Fish

Pat cod fillets dry and season with salt and pepper. Top with lemon slices and thyme sprigs.

4. Add the Fish & Bake

Place fish fillets on top of the roasted potatoes. Return to oven and bake for 20–25 minutes until the fish flakes easily with a fork.


Tips for Success

  • Slice the potatoes uniformly for even roasting.
  • Don’t overcrowd the pan—everything should lay flat to crisp up nicely.
  • Want more color? Broil the sheet pan for the last 2 minutes for a golden finish.
