Ingredients
Instructions
- Adjust rack to top position and preheat oven to 450°F. Wash and dry produce. Peel and dice sweet potato into ½-inch pieces.
- Toss sweet potato on one side of a baking sheet with a drizzle of oil, half the garlic powder, salt and pepper. Roast on top rack until beginning to soften, about 10 minutes.
- While sweet potato roasts, in a small bowl, combine harissa aioli and yogurt. Reserve half the harissa-yogurt sauce in a separate small bowl for serving. Finely chop pepitas. Quarter lemon. Roughly chop cilantro. In a third small bowl, combine panko, pepitas, remaining garlic powder, a drizzle of oil, salt and pepper. Pat tilapia dry with paper towels; season all over with salt and pepper.
- Once sweet potato has roasted 10 minutes, remove sheet from oven; carefully add tilapia, skin sides down, to empty side of sheet. Evenly top tilapia with remaining harissa-yogurt sauce and mound with panko mixture, pressing to adhere. Return to top rack and roast until sweet potato is tender and tilapia is cooked through, 8-10 minutes more.
- In a large bowl, whisk together juice from one lemon wedge, a drizzle of oil, salt and pepper. Once sweet potato is done roasting, transfer to bowl along with mixed greens. Toss to combine.
- Divide sweet potato salad and tilapia between plates. Drizzle reserved harissa yogurt sauce over tilapia and sprinkle with cilantro. Serve with remaining lemon wedges on the side.
Recipe Tips
For extra crunch, toast the panko mixture lightly before adding to the fish.
If you prefer a milder spice, use less harissa aioli or mix with extra yogurt.
Make sure the sweet potato pieces are evenly sized for uniform roasting.

Can I make this recipe dairy-free?
