Recipe Details

- Cook time: N/A
- Servings: N/A
Ingredients
- Cooking spray or olive oil for greasing
- 6 thin frozen white fish fillets (3-4 oz each) – tilapia, cod, or flounder work perfectly
- 1 teaspoon kosher salt, separated
- 1 teaspoon freshly cracked black pepper, separated
- 1 teaspoon dried dill (or your favorite herb blend), separated
- 1 bag (10-12 oz) frozen mixed vegetables
- 2 tablespoons unsalted butter, diced into small pieces
- 2 tablespoons extra virgin olive oil
- 1 bag (14 oz) frozen potato pieces (diced, sliced, or hash browns)
Instructions
- Prepare your oven and dish: Heat oven to 475°F. Generously coat a 9×13-inch baking dish with cooking spray or brush with olive oil to prevent sticking.
- Layer the fish foundation: Place frozen fish fillets in a single layer across the bottom of your prepared dish, skin-side down if applicable. If fillets are too large, simply break them into smaller pieces to fit. Season evenly with half the salt, pepper, and dill.
- Add the vegetable layer: Scatter frozen mixed vegetables directly over the seasoned fish without mixing. Sprinkle with remaining salt, pepper, and dill. Dot the surface with butter pieces and drizzle olive oil evenly across the vegetables.
- Top with potatoes: Spread frozen potatoes in an even layer over everything, creating your final top layer. Resist the urge to stir – the layering is key to proper cooking!
- Bake to perfection: Slide into the preheated oven and bake for 35 minutes, until fish flakes easily with a fork and potatoes are golden. Serve family-style by scooping portions that include all layers.
Tips & Variations
Pro tip: Don’t skip the high oven temperature – 475°F ensures the potatoes get crispy while the fish stays tender. For extra flavor, try swapping dill for Italian seasoning, garlic powder, or even a Cajun spice blend. This recipe is incredibly forgiving, so feel free to use whatever frozen vegetables you have on hand – broccoli, cauliflower, and bell pepper mixes all work wonderfully!
