2tablespoonschopped fresh parsleyplus additional for serving
1small or 1/2 large shallot
½teaspoonkosher saltplus additional for seasoning
¼teaspoonground black pepper
4cupslightly packed tender salad greenslike spinach, arugula, radicchio, or even mixed greens
Place a rack in the center of your oven and preheat the oven to 425 degrees F.
In a small bowl, add the Land O Lakes® Butter with Canola Oil, garlic, parsley, shallot, 1/2 teaspoon salt, and pepper. Zest the lemon right into the bowl (reserve the whole lemon). With a fork, mash the butter with canola oil to smoothly combine all of the ingredients. Cut the whole lemon into thin slices (you will need 8 slices total for the recipe).
Assemble the Packets: Tear off 4 squares of parchment that are at least 12 inches on each side. Lay the sheet flat on a work surface. Place 1 cup of salad greens in the center of a sheet, leaving space at the top and bottom. On top of the greens, place 1 fish fillet so that it runs vertically top to bottom. Lightly sprinkle the fish with salt. With the back of a small spoon, spread one-quarter of the butter mixture on top of the fish. Lay 2 slices of lemon on top of the butter mixture and scatter 6 tomato halves around the fish.
Fold the Parchment Packets: Lift the right and left sides of the paper up and towards the center, directly above the fish. Touch the two sides together and tightly roll them, folding as you go, until you reach the fish. Now, roll and crimp the top and bottom ends, rolling them towards the counter, away from the center of the fish. When you reach the end, tuck the end underneath the fish. Place the packet on a rimmed baking sheet, using the weight of the fish to hold the ends in place (you don't want the packet to come unsealed as it bakes). Repeat with remaining three packets. Reserve any remaining lemon slices for serving.
Place in the oven and bake for 12 to 15 minutes, until the fish is fully cooked through and flakes easily with a fork. Serve warm with reserved lemon slices and additional fresh parsley as desired.
TO STORE: Place leftovers in an airtight storage container in the refrigerator for up to 2 days.
TO REHEAT: Gently reheat fish in a nonstick skillet over medium heat, adding a squeeze of fresh lemon juice to revitalize the flavors. You can also rewarm the fish in the microwave until warm.
TO FREEZE: Store leftover fish in an airtight freezer-safe storage container in the freezer for up to 2 months. Let thaw overnight in the refrigerator before reheating.
TO MAKE AHEAD: Prepare the parchment packets as directed up to 4 hours ahead, and store them in the refrigerator. Bake as directed.
