Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
-
4 tilapia fillets (about 1 lb)
-
2 tablespoons fresh lemon juice
-
3 garlic cloves, minced
-
3 tablespoons extra virgin olive oil
-
2 cups assorted vegetables (bell peppers, zucchini, broccoli)
-
1 teaspoon salt
-
1/2 teaspoon black pepper
Directions
-
I start by preheating my oven to 400°F (200°C).
-
I spray a large baking dish with nonstick cooking spray.
-
In a small bowl, I whisk together olive oil, lemon juice, minced garlic, salt, and pepper. Then I place the tilapia fillets in the dish and drizzle the mixture over them, making sure they’re well coated.
-
I chop the vegetables into bite-sized pieces and arrange them around the fish. Any leftover mixture gets drizzled on top.
-
I bake everything for about 20–25 minutes until the tilapia flakes easily and the vegetables are tender with a slight caramelization.
-
Finally, I plate everything and often squeeze a little extra lemon juice on top before serving.

Variations
Sometimes I swap the tilapia with other mild white fish like cod or haddock, and it works beautifully. I also like experimenting with different vegetables—cherry tomatoes and asparagus are great substitutes. For an extra kick, I sprinkle a little paprika or dill over the fish before baking.
Storage/Reheating
When I have leftovers, I store them in an airtight container in the fridge for up to 3 days. To reheat, I prefer using the oven so the fish stays moist, but the microwave works fine for a quicker option.

FAQs
Can I use frozen tilapia for this recipe?
Yes, I sometimes use frozen tilapia. I just make sure to thaw it completely before cooking so it bakes evenly.
What sides pair well with Lemon Garlic Tilapia?
I often serve it with rice, quinoa, or even mashed potatoes. A light salad on the side also works nicely.
How do I know when the tilapia is done cooking?
I check by gently pressing with a fork—the fish should flake easily, and the flesh should turn opaque.
Can I marinate the tilapia ahead of time?
Yes, I like to marinate it for about 30 minutes before baking. It gives the fish extra flavor and makes it even more tender.
Can I cook this dish on the stovetop instead of the oven?
Absolutely. I sometimes pan-sear the tilapia in a skillet and roast the veggies separately in the oven for a slightly different texture.
Conclusion
I love making this Lemon Garlic Tilapia with Roasted Veggies because it always feels like a plate full of sunshine. The flavors are light yet satisfying, and the whole dish comes together in just about 30 minutes. Whether I’m cooking for myself on a weeknight or hosting a small dinner, this recipe is always a winner.
