Why it works: Arugula and olive work together. They rank in the top 7% of all ingredient pairs, and 655 recipes mention both. Both carry 2-hexenal, which smells green, leafy. The science ↓
The recipe
4 servingsIngredients
Contains: milk, tree nuts, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Preheat the oven to 400°F (200°C) and place a rack in the center.
Make the pesto: in a food processor, combine 3 cups arugula, the minced garlic, chopped pecans, 1/4 cup Parmigiano-Reggiano, the black pepper, a dash of lemon juice and a pinch of sea salt. Pulse while slowly drizzling in the olive oil until a coarse paste forms.
Pat the tilapia fillets dry and season both sides lightly with sea salt to taste.
Arrange the fillets in a baking dish and spread the pesto evenly over the top of each fillet.
Bake for 12 to 15 minutes, until the fish reaches 145°F (63°C) in the thickest part and flakes easily with a fork.
While the fish bakes, toss the 1/2 cup arugula with the 1 tablespoon Parmigiano-Reggiano and a small splash of lemon juice.
Serve each fillet topped with a small handful of the dressed arugula salad.
