Pin This This bright and flavorful Lemon Butter Tilapia Sheet Pan dinner is my favorite pick when I need something healthy, fast, and fuss, free on a busy weeknight. Tender flaky fish roasts alongside colorful vegetables, all coated in a zippy lemon butter sauce. It is so easy to prepare and cleanup is a breeze—I turn to this meal every time I need dinner on the table in under thirty minutes.
The first time I threw this meal together I just needed to use up what was in my fridge—now it is my go-to for those what-do-I-make nights and I always get requests for seconds.

Instructions
- Preheat the Oven:
- Set your oven to four hundred twenty five degrees Fahrenheit or two hundred twenty Celsius and let it fully heat up. Line your large rimmed sheet pan with parchment or foil so nothing sticks and cleaning up is easier.
- Roast the Potatoes:
- In a mixing bowl toss your halved baby potatoes with a tablespoon of olive oil salt and pepper until coated thoroughly. Spread them in a single even layer on your sheet pan and pop them in the oven to roast for ten minutes. This gives them a head start so they are creamy inside and crisp outside.
- Make the Lemon Butter Sauce:
- In a small bowl whisk together the melted butter remaining olive oil lemon juice lemon zest minced garlic dried Italian herbs and chopped fresh parsley. Make sure everything gets evenly combined the zesty butter and herbs will cling to both fish and veggies for big flavor.
- Add More Vegetables:
- After your potatoes have roasted for ten minutes carefully take the pan from the oven. Add the broccoli bell peppers and red onion right onto the pan. Drizzle about half of the lemon butter sauce over the top and toss everything gently so all the veggies are lightly coated.
- Season and Add the Tilapia:
- Pat the tilapia fillets dry with a paper towel and sprinkle both sides with salt and pepper. Nestle the seasoned fish among the vegetables right on the sheet pan. Spoon the rest of the lemon butter sauce evenly over the fillets making sure each one gets some buttery glaze.
- Roast Everything Together:
- Return your sheet pan to the hot oven and bake for another ten to twelve minutes. The tilapia will cook fast so keep an eye out—it is ready when it flakes easily with a fork and the vegetables are perfectly tender.
- Garnish and Serve:
- Finish with a sprinkle of fresh parsley and serve your tilapia with a few lemon wedges on the side. The fresh citrus makes every bite pop. Enjoy right away for the very best texture.
Pin This Broccoli is always my favorite because it soaks up the lemon butter and gets a little crispy on the edges. The first time I served this my brother ate every last piece of potato before anyone else had seconds and now it is a running joke in our family.
Storage Tips
Store leftovers in an airtight container in the fridge for up to two days. To keep the fish from drying out reheat gently in the oven covered with foil. Avoid microwaving the fish if you can because it can turn rubbery. If you want to prep ahead you can chop the vegetables and mix the sauce the night before.
Ingredient Substitutions
Swap tilapia for any mild white fish like cod or haddock. Salmon is also a fun richer option but will need an extra few minutes of bake time. You can replace potatoes with sweet potatoes for a touch of sweetness or swap in asparagus green beans or zucchini when in season. For dairy-free just use a plant-based butter or extra olive oil.
Serving Suggestions
Serve atop fluffy steamed rice quinoa or even cauliflower rice to soak up all the extra sauce. For a more elaborate meal I love adding a side salad with arugula and a simple vinaigrette. Warm crusty bread makes sure no drop of the lemony butter goes to waste.
Cultural and Historical Context
Sheet pan meals have deep roots in busy American kitchens where quick cleanup is key. Tilapia is a mild affordable fish eaten around the world and its delicate flavor pairs perfectly with Mediterranean flavors like lemon fresh herbs and olive oil. I always feel like I am on vacation when I cook with such bright and fresh ingredients.
Seasonal Adaptations
Add fresh baby carrots or snap peas in spring for extra crunch Try sliced zucchini or yellow squash in summer for a lighter veggie mix Root vegetables like parsnips or sweet potatoes are cozy options for fall and winter
Pin This Friends always tell me this recipe made them fans of cooking fish at home even if they were hesitant before. My aunt says she made it with frozen broccoli and it still turned out perfect.
