One pan dinners are my favorite during the week. This lemon pepper tilapia sheet pan dinner is not only quick and easy to prepare but also a cinch to clean up. It is also naturally Whole30 and Paleo compliant and also low carb so if you are on a low carb diet or just avoiding carbs in general, this sheet pan dinner recipe is a great option!
How to Make Lemon Pepper Tilapia
To make a sheet pan dinner I line a large baking sheet with aluminium foil and bake everything together. I like to drizzle olive oil, sea salt and freshly ground pepper on my vegetables before roasting so I start with those first. I gently toss the vegetables right on the baking sheet! Why clean more dishes than necessary?
How Long to Bake Tilapia
If you bake your tilapia in the oven at 400 degrees, it will take approximately 15 minutes to cook. Exact timing though really depends upon the size of your fish. For thicker filets it might take a bit longer and smaller filets a bit less. You’ll know your fish is done when it is nice and flaky. I like to broil my tilapia for a minute or two before taking it out of the oven.
I love the flavor of this lemon pepper tilapia and find it also tastes amazing served with rice. These roasted green beans still have a nice crunch to them while the tomatoes literally burst in your mouth. (If you loved roasted vegetables or are eating low carb, try my roasted radishes! They make a great potato substitute.)
I’ve made this meal twice in the past month because it is just so easy and delicious. It works great as leftovers for lunch the next day.
