Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Cut the sweet potato into thin wedges and toss them in a bowl with 1 teaspoon of olive oil, salt, and pepper.
Spread the sweet potato wedges on the baking sheet and roast for 15 minutes.
While the potatoes roast, combine the almond flour, smoked paprika, and garlic powder in a shallow dish.
Pat the cod fillet dry with a paper towel, brush the top with the remaining teaspoon of olive oil, and press the almond flour mixture firmly onto the fish.
Remove the baking sheet from the oven, move the potatoes to one side, and add the green beans and the crusted cod.
Return the sheet to the oven and bake for an additional 12-15 minutes until the cod is opaque and flakes easily with a fork.
Serve immediately with a fresh squeeze of lemon over the fish.
