Old Bay Tilapia, Sweet Potatoes and Veggies

Total Time
Prep 15 mins
Cook 45 mins

I'm not a huge fan of the classic sweet potato casserole, so I concocted this dish. The reds, oranges, and yellows are perfect for fall entertaining! Then I decided that the flavors would complement tilapia, orange roughy, or any white fish really well. It was a hit as both a vegetable side and as a full meal.

Ingredients Nutrition

  • 2 tablespoons olive oil
  • 3 large sweet potatoes
  • 1 red pepper
  • 1 yellow pepper
  • 1 medium red onion
  • 1 medium tomatoes
  • 2 teaspoons Old Bay Seasoning (more if you want it spicier!)
  • 12 teaspoon black pepper (again, you can add more)
  • 1 tablespoon parsley
  • 18 ounces tilapia fillets (about 3 filets) or 18 ounces other white fish (about 3 filets)


  1. Preheat oven to 350°F.
  2. Wash and scrub the sweet potatoes (or remove the skin, but I like to keep it). Cut them into cubes about 3/4 inch in size. Place in a 13x9 inch pan.
  3. Chop the onion and peppers into 1 inch by 1/4 inch slices. (I think that the dish look better when they are this size. It's really not important how large they are.) Add to the pan.
  4. Dice tomato. Add to pan with other veggies.
  5. Add olive oil, old bay seasoning, pepper, and parsley to taste. Stir well to coat veggies.
  6. Bake in oven for 25 minutes.
  7. Add tilapia filets to bottom of pan by scooping veggies aside and covering the fish with some of the veggies. Bake additional 20 minutes until fish flakes.

Excellent and easy -- my favorite combination! And this dish looked great, too. I used 3 tablespoons of Old Bay Seasoning and at least a teaspoon of black pepper. I had 4 sweet potatoes on hand and so I used them all. I did cook the vegetables a little longer than suggested and they were great with the tilapia. We loved this one -- thanks!

This was really good. I used orange roughy instead of tilapia. Other than that I followed the recipe as written using Old Bay Seasoning instead of commercial Old Bay Seasoning. Thankyou for posting. I'll be making this again.

Very good! I was looking for a tilapia recipe and a sweet potato recipe, and found yours instead -- a perfect solution. Flavors blended beautifully, and there was just enough flavor to be interesting, but not to be overpowering. We thought that the vegetables weren't cooked enough, though; we prefer 'em a little less crunchy. Next time I make it I'll cook 'em at 400 for at least 40 minutes, then drop the heat when I add the tilapia. But the tilapia turned out BEAUTIFULLY -- cooked to perfection! And it was a beautiful dish to look at -- the colors were spectacular. Sorry I didn't take a photo!
