Old Bay Tilapia with Sweet Potatoes and Roasted Vegetables

I’ve always believed that the best dishes emerge from happy accidents or a genuine desire to tweak the familiar into something uniquely yours. For me, that journey started with a lingering apprehension towards the often overly sweet, marshmallow-laden classic sweet potato casserole. I wanted something that celebrated the natural sweetness of sweet potatoes, balanced with savory elements, and packed with vibrant color, especially as the autumn leaves began to turn. This vision led me to combine sweet potatoes with a medley of bell peppers and red onion, all kissed by the irresistible aroma of Old Bay Seasoning. The vibrant reds, oranges, and yellows that emerged from the oven were a feast for the eyes, and I knew this could stand beautifully on its own as a side. It wasn’t long before I thought, “What if this could be a complete meal?” And thus, the humble tilapia fillet found its place, nestled amongst these roasted jewels, transforming a simple side into a complete, satisfying dish that quickly became a go-to in my kitchen.

• Cook Time: 45 minutes
• Total Time: 1 hour 5 minutes

• Yield: One 13×9 inch pan
• Dietary Type: Gluten-Free, Dairy-Free

Ingredients

This recipe is a symphony of simple, wholesome ingredients that come together to create a dish that’s both comforting and exciting. The star, of course, is the Old Bay Seasoning, a blend that conjures seaside breezes and backyard barbecues with just a sprinkle.

• 2 tablespoons olive oil
• 3 large sweet potatoes, washed and scrubbed
• 1 red bell pepper, cored, seeded, and chopped
• 1 yellow bell pepper, cored, seeded, and chopped
• 1 medium red onion, peeled and chopped
• 1 medium tomato, diced
• 2 teaspoons Old Bay Seasoning (feel free to add more if you love a spicier kick!)
• 1/2 teaspoon black pepper (again, adjust to your preference)
• 1 tablespoon chopped fresh parsley
• 18 ounces tilapia fillets (about 3 fillets), or any other firm white fish like orange roughy

Equipment Needed

While this dish is delightfully unfussy, a few basic kitchen tools will ensure a smooth cooking experience:

• A sturdy knife for chopping vegetables.
• A cutting board.
• A large baking pan (a 13×9 inch pan is ideal).
• A large bowl for tossing the vegetables.
• A spoon or spatula for stirring and arranging.

Instructions

Bringing this vibrant dish to life is a straightforward process, allowing the natural flavors of the ingredients to shine. The gentle roasting of the vegetables brings out their inherent sweetness, while the Old Bay seasoning provides a savory counterpoint.

1. Preheat your oven to 350°F (175°C). Getting the oven to the right temperature is the first crucial step for even cooking.
2. Prepare the sweet potatoes. Wash and scrub the sweet potatoes thoroughly. For this recipe, I personally love leaving the skins on for added texture and nutrients, but you’re welcome to peel them if you prefer. Cut the sweet potatoes into cubes approximately 3/4 inch in size. Place these seasoned cubes into your 13×9 inch baking pan.
3. Add the other vegetables. Chop the red onion and both bell peppers into slices that are roughly 1 inch by 1/4 inch. While the exact size isn’t critical to the success of the dish, I find this size provides a pleasing visual appeal and ensures they cook through nicely alongside the sweet potatoes. Dice the tomato and add it to the pan with the other chopped vegetables.
4. Season the vegetables. Drizzle the olive oil over the vegetables in the pan. Sprinkle in the Old Bay Seasoning, black pepper, and chopped parsley. Using your hands or a large spoon, stir everything together well, ensuring that all the vegetables are evenly coated with the oil and seasonings. This even coating is key to developing those beautiful roasted flavors.
5. Initial Bake. Place the pan into the preheated oven and bake for 25 minutes. This initial baking period allows the vegetables to soften and begin to caramelize, building a delicious base for the fish.
6. Add the tilapia. After 25 minutes, carefully remove the pan from the oven. Gently scoop the roasted vegetables aside to create space at the bottom of the pan. Place the tilapia fillets directly onto the bottom of the pan, nestled amongst the vegetables. Then, cover the fish with some of the surrounding vegetables and seasonings.
7. Final Bake. Return the pan to the oven and bake for an additional 20 minutes, or until the tilapia is opaque and flakes easily with a fork. The exact time may vary slightly depending on the thickness of your fillets and your oven, so keep an eye on it during these last minutes.

Expert Tips & Tricks

• Don’t Overcrowd the Pan: Ensure there’s a bit of breathing room between the vegetable pieces. Overcrowding will cause them to steam rather than roast, which will result in a less desirable texture. If your pan seems too full, consider using a slightly larger one or splitting the ingredients between two pans.
• Uniform Cubes for Even Cooking: While I’ve mentioned it’s not critical, cutting your sweet potatoes into roughly uniform 3/4-inch cubes will ensure they all cook at the same rate. This prevents some from being mushy while others are still firm.
• Adjust Old Bay to Your Palate: Old Bay Seasoning has a unique blend of spices. Start with the recommended amount and taste your vegetables after the initial bake. You can always add a touch more before adding the fish if you desire a more pronounced flavor.
• Checking for Doneness: For the fish, a quick test is to gently press the thickest part with a fork. If it flakes apart easily and is no longer translucent, it’s perfectly cooked. Overcooked fish can become dry and tough.

Serving & Storage Suggestions

This Old Bay Tilapia with Sweet Potatoes and Roasted Vegetables is a beautiful dish that stands proudly on its own. Serve it directly from the baking pan, allowing the vibrant colors to be the star of your table. It’s wonderful as a light, satisfying meal.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm individual portions in a microwave or a covered skillet over low heat, being careful not to overcook the fish. The roasted vegetables will continue to deepen in flavor as they sit.

Variations & Substitutions

While this recipe is delightful as is, feel free to explore its versatility:

• Spice it Up: For a spicier kick, add a pinch of cayenne pepper or red pepper flakes to the vegetable seasoning mix.
• Other White Fish: As mentioned, other white fish like cod, haddock, or halibut work wonderfully. Adjust the cooking time slightly based on the thickness of the fillets.
• Seasonal Vegetables: In warmer months, consider adding zucchini or yellow squash, ensuring they are cut into similar sizes for even cooking.
• Herb Swap: If fresh parsley isn’t available, a teaspoon of dried parsley can be used, though fresh adds a brighter note.

FAQs

Q: Can I prepare the vegetables ahead of time?
A: Yes, you can chop the sweet potatoes, bell peppers, and onion a day in advance and store them in an airtight container in the refrigerator. Add the diced tomato and seasonings just before baking to prevent them from becoming watery.

Q: My tilapia fillets are very thin. How do I avoid overcooking them?
A: If your fillets are particularly thin, check them for doneness after about 15 minutes of the final bake. They cook very quickly, and it’s better to err on the side of undercooking slightly and letting residual heat finish the job than to end up with dry fish.

Q: What kind of pan is best for this recipe?
A: A standard 13×9 inch baking pan works perfectly. Any oven-safe pan of similar size that allows for even heat distribution will be suitable.

Q: Is this dish suitable for meal prep?
A: Absolutely! This dish reheats quite well, making it an excellent option for lunches or weeknight dinners. Just be sure to store it properly in the refrigerator.

Q: Can I add other spices besides Old Bay?
A: While Old Bay is key to the flavor profile, feel free to experiment. A pinch of garlic powder or onion powder can complement the existing flavors, but be mindful not to overpower the star seasoning.
