Preheat oven to 400°F and cut sweet potatoes into 1-inch cubes and green beans into 2-inch pieces; toss with 2 tbsp olive oil, salt, and pepper on a sheet pan and roast for 12 minutes.
Meanwhile, pat halal cod fillets dry and arrange on a second sheet pan, drizzle with 2 tbsp olive oil, season with paprika, salt, and pepper.
Add minced garlic to cod, squeeze lemon juice over top, and place in oven alongside vegetables for 10 minutes until cod flakes easily.
Check that vegetables are tender and cod is opaque throughout.
Divide cod, vegetables, and pan juices among plates and serve immediately.
