Ingredients

- sweet potato 1/2 medium
- olive oil 1 tbsp
Method

Prepare the Sweet Potato.
Preheat your oven to 400°F (200°C). Wash the sweet potato thoroughly and prick it several times with a fork to allow steam to escape. Place it on a baking sheet and bake for about 25-30 minutes, or until tender when pierced with a fork.
Tip: You can start baking the sweet potato first since it takes the longest. -
Prepare the Spinach.
While the sweet potato is baking, rinse the spinach leaves under cold water and drain well. Heat half a tablespoon of olive oil in a large skillet over medium heat. Add the spinach and sauté for 3-4 minutes until wilted but still bright green. Season lightly with salt and pepper if desired. Remove from heat and set aside.
Tip: Avoid overcooking spinach to keep its vibrant color and nutrients. -
Season the Tuna Steak.
Pat the tuna steak dry with paper towels. Lightly brush both sides with the remaining half tablespoon of olive oil. Season with a pinch of salt and freshly ground black pepper.
Tip: Drying the tuna helps achieve a nice sear. -
Sear the Tuna Steak.
Heat a non-stick skillet or cast-iron pan over medium-high heat until very hot. Place the tuna steak in the pan and sear for about 2 minutes on each side for medium-rare doneness. Adjust time slightly if you prefer it more cooked. Remove from heat and let it rest for 2 minutes before slicing.
Tip: Avoid moving the tuna while searing to get a good crust. -
Plate and Serve.
Slice the tuna steak against the grain into thick slices. Place the sautéed spinach and baked sweet potato halves on the plate alongside the tuna. Optionally, drizzle a little extra olive oil over the spinach or sweet potato for added flavor.
Tip: Serve immediately to enjoy the tuna at its best texture and flavor.
Pro tips
- Use a very hot pan to sear the tuna quickly and lock in moisture.
- Let the tuna rest briefly after cooking to retain juices.
