Save There's something truly magical about a meal that's both incredibly simple yet bursting with fresh, vibrant flavors. These Lemon Garlic Tilapia Packets are the epitome of easy elegance - delicate white fish bathed in zesty citrus and aromatic garlic, steamed to perfection alongside crisp green beans. The foil packet cooking method not only locks in moisture and flavor but also makes cleanup a breeze. Perfect for busy weeknights when you want something nutritious without spending hours in the kitchen.
Save This recipe takes advantage of tilapia's mild nature, allowing the lemon and garlic to shine. The green beans and red onion not only add nutritional value but also absorb the aromatic marinade as everything steams together. When you open those foil packets at the dinner table, the rush of fragrant steam will make your mouth water instantly. It's a sensory experience that belies the dish's simple preparation.
- 4 tilapia fillets (4 oz / 115 g each), fresh or thawed
- 12 oz (340 g) fresh green beans, trimmed
- 1 small red onion, thinly sliced
- 1 lemon, thinly sliced
- 3 tablespoons fresh lemon juice (from about 1 lemon)
- 2 tablespoons olive oil
- 2 large garlic cloves, minced
- 1 teaspoon dried oregano (or Italian seasoning)
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 2 tablespoons chopped fresh parsley (optional, for garnish)
- Prepare the oven and marinade
- Preheat oven to 400°F (200°C). In a small bowl, whisk together lemon juice, olive oil, garlic, oregano, salt, and black pepper.
- Assemble the foil packets
- Lay out 4 large sheets of aluminum foil. Divide green beans evenly among the centers of each sheet. Top green beans with sliced red onion.
- Add the tilapia
- Pat tilapia fillets dry. Place one fillet on top of each pile of vegetables.
- Season everything
- Drizzle each fillet with the prepared lemon-garlic marinade. Top each fillet with 2–3 lemon slices.
- Seal the packets
- Fold the foil over fish and vegetables, sealing tightly to form a packet. Place packets on a baking sheet.
- Bake to perfection
- Bake for 18–20 minutes, until tilapia is opaque and flakes easily with a fork.
- Serve
- Carefully open packets (steam will be hot). Garnish with fresh parsley and serve immediately.
For the best results, make sure your foil sheets are large enough to fully enclose the fish and vegetables with room for the steam to circulate. If your green beans are particularly thick, consider blanching them for 2 minutes before adding to the packets to ensure they cook through completely. The packets can be assembled up to 4 hours ahead and refrigerated until you're ready to bake them, making this an excellent make-ahead meal option.
This versatile recipe welcomes many variations. Swap the tilapia for cod, sole, or another mild white fish if desired. For a Mediterranean twist, add a few kalamata olives and a sprinkle of feta cheese (though this will add calories and dairy). Vegetable options are endless - try adding cherry tomatoes, zucchini slices, or yellow squash. For those who enjoy a hint of heat, add a pinch of chili flakes to the marinade. The recipe remains gluten-free and low-calorie with these modifications.
Serve these tilapia packets straight from the foil for a rustic presentation, or carefully transfer the contents to plates for more elegant dining. While the meal is complete on its own at 295 calories per serving, you might consider adding a side of quinoa or brown rice for a heartier meal. A simple lemon wedge on the side allows diners to add an extra squeeze of brightness if desired. For a special touch, sprinkle with additional fresh herbs like dill or chives just before serving.
