Ingredients

To bring this beautiful dish to life, you’ll need these components:

• 2 large red onions, cut into 1/4-inch wedges
• 2 tablespoons olive oil
• 1 (10 ounce) package frozen artichoke hearts, thawed
• 1 cup small grape tomatoes
• 1 teaspoon grated lemon zest
• 1 garlic clove, minced
• 2 tablespoons chopped fresh parsley
• 4 (6 ounce) skinless tilapia fillets

Equipment Needed

For this recipe, you’ll find the following tools helpful:

• A 13×9-inch baking dish
• A small bowl
• An oven

Instructions

Embarking on this culinary journey is straightforward, resulting in a delightful and wholesome meal.

1. Begin by preheating your oven to 400°F (200°C). This initial temperature is crucial for coaxing the sweetness out of the red onions.
2. In your 13×9-inch baking dish, combine the cut red onions and the olive oil. Toss them gently to ensure the onions are lightly coated.
3. Spread the oiled onions in an even layer across the bottom of the baking dish.
4. Place the dish in the preheated oven and roast the onions until they are tender and have turned a beautiful golden hue. This typically takes about 35 minutes. Keep an eye on them; ovens can vary, and we’re aiming for that perfect caramelization.
5. Once the onions have reached their golden perfection, carefully remove the baking dish from the oven.
6. Now, stir in the thawed artichoke hearts and the grape tomatoes directly into the dish with the softened onions. Give everything a gentle mix to distribute the new additions.
7. In a small, separate bowl, combine the chopped parsley, grated lemon zest, and minced garlic. Mix these aromatic ingredients together and set this mixture aside; it will be our flavor boost at the end.
8. It’s time to elevate the oven temperature. Increase your oven temperature to 450°F (230°C). This higher heat is perfect for quickly cooking the fish and slightly blistering the vegetables.
9. Carefully push the vegetable mixture to one side of the baking dish, creating space for the tilapia.
10. Arrange the skinless tilapia fillets in the cleared section of the dish.
11. Gently spoon some of the roasted vegetables over the top of each tilapia fillet. This will infuse the fish with wonderful flavors as it cooks.
12. Sprinkle the reserved parsley, lemon zest, and garlic mixture evenly over the fish and vegetables.
13. Return the baking dish to the hot oven and roast until the fish is opaque and flakes easily with a fork. The cooking time here is brief and depends on the thickness of your fillets. For thinner fillets, this might take around 5 minutes, while thicker fillets could require 12 to 15 minutes. It’s essential not to overcook the tilapia to maintain its delicate texture.

Expert Tips & Tricks

To elevate your Roasted Tilapia experience even further, consider these professional insights:

• Thawing Artichoke Hearts: Ensure your frozen artichoke hearts are completely thawed. This allows them to roast and soften properly without releasing excess moisture into the dish. You can thaw them by placing them in a colander and running cool water over them, or by leaving them at room temperature for about 30 minutes.
• Selecting Tomatoes: While grape tomatoes are specified, feel free to use cherry tomatoes as well. The key is small, sweet tomatoes that will burst and release their juices as they roast.
• Doneness Test for Fish: The most reliable way to check if your tilapia is done is by gently inserting a fork into the thickest part of a fillet. If it flakes apart easily and the flesh is opaque throughout, it’s ready. If there’s any pinkness or resistance, give it another minute or two.
• Adjusting for Oven Variations: Every oven is a little different! It’s always a good idea to get to know your oven’s hot spots and tendencies. If you find your oven runs hot, you might want to reduce the initial roasting time for the onions slightly, or keep a closer eye on the fish during the final cooking phase.
• Prepping Ahead: You can pre-chop the red onions, mince the garlic, and zest the lemon a day in advance and store them in airtight containers in the refrigerator. This will significantly cut down on your prep time when you’re ready to cook.

Serving & Storage Suggestions

This dish is at its absolute best served piping hot, straight from the oven. The aromas alone are enough to make your mouth water! It pairs beautifully with a simple quinoa pilaf, a light green salad dressed with a lemon vinaigrette, or even some crusty baguette to soak up any delicious pan juices.

For leftovers, allow the dish to cool completely before transferring it to an airtight container. Store it in the refrigerator for up to 2 days. Reheating can be done gently in a low oven (around 300°F/150°C) or on the stovetop over low heat to prevent the tilapia from drying out.

Variations & Substitutions

While this recipe is wonderful as is, feel free to experiment with its core elements:

• Fish Variety: If tilapia isn’t your preference, other flaky white fish like cod, haddock, or snapper would also work beautifully in this preparation. Adjust the cooking time based on the thickness of your chosen fish.
• Vegetable Additions: Enhance the vegetable medley with other Mediterranean-inspired ingredients. Sliced kalamata olives, halved red bell peppers, or even some fresh spinach wilted in during the last few minutes of cooking would be fantastic additions.
• Herbal Touches: While parsley is classic, consider using fresh dill or oregano for a different herbaceous profile. A pinch of red pepper flakes added to the vegetable mix would provide a subtle warmth.
• Lemon Intensity: If you love a strong lemon flavor, you can add a squeeze of fresh lemon juice to the dish just before serving.

FAQs (Frequently Asked Questions)

Q: Can I use fresh artichoke hearts instead of frozen?
A: Absolutely! If using fresh artichoke hearts, you’ll need to trim them, remove the fuzzy choke, and possibly quarter them. They will then need to be cooked a bit longer during the initial onion roasting phase until tender.

Q: My tilapia fillets are very thin. Will they overcook quickly?
A: Yes, thin fillets will cook much faster. Keep a very close eye on them, and they might only need 5-7 minutes in the 450°F oven. A fork test is your best friend here.

Q: What kind of pan is best for this recipe?
A: A 13×9-inch baking dish is ideal because it provides ample surface area for the vegetables to roast evenly and for the fish to cook without overcrowding.

Q: Can I prepare the vegetable mixture ahead of time?
A: You can roast the onions and combine them with the artichoke hearts and tomatoes a few hours in advance. Store them covered in the refrigerator. Add the fish and parsley mixture just before baking.

Q: Is this recipe suitable for meal prep?
A: Yes, this dish holds up well for meal prep. Simply portion the leftovers into individual containers for easy lunches or dinners throughout the week.
